Eye-movement control during reading depends on foveal and parafoveal information. If the parafoveal preview of the next word is suppressed, reading is less efficient. A linear mixed model (LMM) reanalysis of McDonald (2006) confirmed his observation that preview benefit may be limited to parafoveal words that have been selected as the saccade target. Going beyond the original analyses, in the same LMM, we examined how the preview effect (i.e., the difference in single-fixation duration, SFD, between random-letter and identical preview) depends on the gaze duration on the pretarget word and on the amplitude of the saccade moving the eye onto the target word. There were two key results: (a) The shorter the saccade amplitude (i.e., the larger preview space), the shorter a subsequent SFD with an identical preview; this association was not observed with a random-letter preview. (b) However, the longer the gaze duration on the pretarget word, the longer the subsequent SFD on the target, with the difference between random-letter string and identical previews increasing with preview time. A third pattern-increasing cost of a random-letter string in the parafovea associated with shorter saccade amplitudes-was observed for target gaze durations. Thus, LMMs revealed that preview effects, which are typically summarized under "preview benefit", are a complex mixture of preview cost and preview benefit and vary with preview space and preview time. The consequence for reading is that parafoveal preview may not only facilitate, but also interfere with lexical access.

Theories of preview benefit in reading hinge on integration across saccades and the idea that preview benefit is greater the more similar the preview and target are. Schotter (2013) reported preview benefit from a synonymous preview, but it is unclear whether this effect occurs because of similarity between the preview and target (integration), or because of contextual fit of the preview—synonyms satisfy both accounts. Studies in Chinese have found evidence for preview benefit for words that are unrelated to the target, but are contextually plausible (Yang, Li, Wang, Slattery, & Rayner, 2014; Yang, Wang, Tong, & Rayner, 2012), which is incompatible with an integration account but supports a contextual fit account. Here, we used plausible and implausible unrelated previews in addition to plausible synonym, antonym, and identical previews to further investigate these accounts for readers of English. Early reading measures were shorter for all plausible preview conditions compared to the implausible preview condition. In later reading measures, a benefit for the plausible unrelated preview condition was not observed. In a second experiment, we asked questions that probed whether the reader encoded the preview or target. Readers were more likely to report the preview when they had skipped the word and not regressed to it, and when the preview was plausible. Thus, under certain circumstances, the preview word is processed to a high level of representation (i.e., semantic plausibility) regardless of its relationship to the target, but its influence on reading is relatively short-lived, being replaced by the target word, when fixated.

Synonyms Provide Semantic Preview Benefit in English

2013-01-01

While orthographic and phonological preview benefits in reading are uncontroversial (see Schotter, Angele, & Rayner, 2012 for a review), researchers have debated the existence of semantic preview benefit with positive evidence in Chinese and German, but no support in English. Two experiments, using the gazecontingent boundary paradigm (Rayner, 1975), show that semantic preview benefit can be observed in English when the preview and target are synonyms (share the same or highly similar meaning, e.g., curlers-rollers). However, no semantic preview benefit was observed for semantic associates (e.g., curlers-styling). These different preview conditions represent different degrees to which the meaning of the sentence changes when the preview is replaced by the target. When this continuous variable (determined by a norming procedure) was used as the predictor in the analyses, there was a significant relationship between it and all reading time measures, suggesting that similarity in meaning between what is accessed parafoveally and what is processed foveally may be an important influence on the presence of semantic preview benefit. Why synonyms provide semantic preview benefit in reading English is discussed in relation to (1) previous failures to find semantic preview benefit in English and (2) the fact that semantic preview benefit is observed in other languages even for non-synonymous words. Semantic preview benefit is argued to depend on several factors—attentional resources, depth of orthography, and degree of similarity between preview and target. PMID:24347813

Flipping organic chemistry course: Possibilities and challenges

NASA Astrophysics Data System (ADS)

Cha, J.; Kim, H. B.

2016-06-01

The flipped classroom approach was applied to an introductory organic chemistry course. A total of 76 video clips (15 hours of running time) were developed and delivered to 41 sophomores (21 females and 20 males) through Youtube in addition to the university's learning management system. The students were asked to preview the lecture contents before each class by watching a pre-class video. For in-class activities, exercise problems were presented to groups of 3-5 students. An instructor and a teaching assistant guided each group to solve problems cooperatively, monitored the students’ group activity and answered their questions. At the end of every chapter, the students were asked to evaluate their group work and personal preparedness for the class and also to write a short reflective journal. The muddiest point of each chapter, i.e., the topic posing the most difficulty to students’ understanding, was surveyed through Google Forms®. The students liked watching the videos before each class and performing student-centered, in-class group activities but a few limitations were also found and reported.

Semantic preview benefit during reading.

PubMed

Hohenstein, Sven; Kliegl, Reinhold

2014-01-01

Word features in parafoveal vision influence eye movements during reading. The question of whether readers extract semantic information from parafoveal words was studied in 3 experiments by using a gaze-contingent display change technique. Subjects read German sentences containing 1 of several preview words that were replaced by a target word during the saccade to the preview (boundary paradigm). In the 1st experiment the preview word was semantically related or unrelated to the target. Fixation durations on the target were shorter for semantically related than unrelated previews, consistent with a semantic preview benefit. In the 2nd experiment, half the sentences were presented following the rules of German spelling (i.e., previews and targets were printed with an initial capital letter), and the other half were presented completely in lowercase. A semantic preview benefit was obtained under both conditions. In the 3rd experiment, we introduced 2 further preview conditions, an identical word and a pronounceable nonword, while also manipulating the text contrast. Whereas the contrast had negligible effects, fixation durations on the target were reliably different for all 4 types of preview. Semantic preview benefits were greater for pretarget fixations closer to the boundary (large preview space) and, although not as consistently, for long pretarget fixation durations (long preview time). The results constrain theoretical proposals about eye movement control in reading. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

Communicating headings and preview sentences in text and speech.

Lorch, Robert F; Chen, Hung-Tao; Lemarié, Julie

2012-09-01

Two experiments tested the effects of preview sentences and headings on the quality of college students' outlines of informational texts. Experiment 1 found that performance was much better in the preview sentences condition than in a no-signals condition for both printed text and text-to-speech (TTS) audio rendering of the printed text. In contrast, performance in the headings condition was good for the printed text but poor for the auditory presentation because the TTS software failed to communicate nonverbal information carried by the visual headings. Experiment 2 compared outlining performance for five headings conditions during TTS presentation. Using a theoretical framework, "signaling available, relevant, accessible" (SARA) information, to provide an analysis of the information content of headings in the printed text, the manipulation of the headings systematically restored information that was omitted by the TTS application in Experiment 1. The result was that outlining performance improved to levels similar to the visual headings condition of Experiment 1. It is argued that SARA is a useful framework for guiding future development of TTS software for a wide variety of text signaling devices, not just headings.

Semantic preview benefit in reading English: The effect of initial letter capitalization.

PubMed

Rayner, Keith; Schotter, Elizabeth R

2014-08-01

A major controversy in reading research is whether semantic information is obtained from the word to the right of the currently fixated word (word n + 1). Although most evidence has been negative in English, semantic preview benefit has been observed for readers of Chinese and German. In the present experiment, we investigated whether the discrepancy between English and German may be attributable to a difference in visual properties of the orthography: the first letter of a noun is always capitalized in German, but is only occasionally capitalized in English. This visually salient property may draw greater attention to the word during parafoveal preview and thus increase preview benefit generally (and lead to a greater opportunity for semantic preview benefit). We used English target nouns that can either be capitalized (e.g., We went to the critically acclaimed Ballet of Paris while on vacation.) or not (e.g., We went to the critically acclaimed ballet that was showing in Paris.) and manipulated the capitalization of the preview accordingly, to determine whether capitalization modulates preview benefit in English. The gaze-contingent boundary paradigm was used with identical, semantically related, and unrelated previews. Consistent with our hypothesis, we found numerically larger preview benefits when the preview/target was capitalized than when it was lowercase. Crucially, semantic preview benefit was not observed when the preview/target word was not capitalized, but was observed when the preview/target word was capitalized.

Reversed preview benefit effects: Forced fixations emphasize the importance of parafoveal vision for efficient reading

PubMed Central

Schotter, Elizabeth R.; Leinenger, Mallorie

2016-01-01

Current theories of eye movement control in reading posit that processing of an upcoming parafoveal preview word is used to facilitate processing of that word once it is fixated (i.e., a foveal target word). This preview benefit is demonstrated by shorter fixation durations in the case of valid (i.e., identical or linguistically similar) compared to invalid (i.e., dissimilar) preview conditions. However, we suggest that processing of the preview can directly influence fixation behavior on the target, independent of similarity between them. In Experiment 1, unrelated high and low frequency words were used as orthogonally crossed previews and targets and we observed a reversed preview benefit for low frequency targets—shorter fixation durations with an invalid, higher frequency preview compared to a valid, low frequency preview. In Experiment 2, the target words were replaced with orthographically legal and illegal nonwords and we found a similar effect of preview frequency on fixation durations on the targets, as well as a bimodal distribution in the illegal nonword target conditions with a denser early peak for high than low frequency previews. In Experiment 3, nonwords were used as previews for high and low frequency targets, replicating standard findings that “denied” preview increases fixation durations and the influence of target properties. These effects can be explained by forced fixations, cases in which fixations on the target were shortened as a consequence of the timing of word recognition of the preview relative to the time course of saccade programming to that word from the prior one. That is, the preview word was (at least partially) recognized so that it should have been skipped, but the word could not be skipped because the saccade to that word was in a non-labile stage. In these cases, the system pre-initiates the subsequent saccade off the upcoming word to the following word and the intervening fixation is short. PMID:27732044

An Empirical Human Controller Model for Preview Tracking Tasks.

van der El, Kasper; Pool, Daan M; Damveld, Herman J; van Paassen, Marinus Rene M; Mulder, Max

2016-11-01

Real-life tracking tasks often show preview information to the human controller about the future track to follow. The effect of preview on manual control behavior is still relatively unknown. This paper proposes a generic operator model for preview tracking, empirically derived from experimental measurements. Conditions included pursuit tracking, i.e., without preview information, and tracking with 1 s of preview. Controlled element dynamics varied between gain, single integrator, and double integrator. The model is derived in the frequency domain, after application of a black-box system identification method based on Fourier coefficients. Parameter estimates are obtained to assess the validity of the model in both the time domain and frequency domain. Measured behavior in all evaluated conditions can be captured with the commonly used quasi-linear operator model for compensatory tracking, extended with two viewpoints of the previewed target. The derived model provides new insights into how human operators use preview information in tracking tasks.

Effects of workload preview on task scheduling during simulated instrument flight.

PubMed

Andre, A D; Heers, S T; Cashion, P A

1995-01-01

Our study examined pilot scheduling behavior in the context of simulated instrument flight. Over the course of the flight, pilots flew along specified routes while scheduling and performing several flight-related secondary tasks. The first phase of flight was flown under low-workload conditions, whereas the second phase of flight was flown under high-workload conditions in the form of increased turbulence and a disorganized instrument layout. Six pilots were randomly assigned to each of three workload preview groups. Subjects in the no-preview group were not given preview of the increased-workload conditions. Subjects in the declarative preview group were verbally informed of the nature of the flight workload manipulation but did not receive any practice under the high-workload conditions. Subjects in the procedural preview group received the same instructions as the declarative preview group but also flew half of the practice flight under the high-workload conditions. The results show that workload preview fostered efficient scheduling strategies. Specifically, those pilots with either declarative or procedural preview of future workload demands adopted an efficient strategy of scheduling more of the difficult secondary tasks during the low-workload phase of flight. However, those pilots given a procedural preview showed the greatest benefits in overall flight performance.

A Drastic Change in Background Luminance or Motion Degrades the Preview Benefit.

PubMed

Osugi, Takayuki; Murakami, Ikuya

2017-01-01

When some distractors (old items) precede some others (new items) in an inefficient visual search task, the search is restricted to new items, and yields a phenomenon termed the preview benefit. It has recently been demonstrated that, in this preview search task, the onset of repetitive changes in the background disrupts the preview benefit, whereas a single transient change in the background does not. In the present study, we explored this effect with dynamic background changes occurring in the context of realistic scenes, to examine the robustness and usefulness of visual marking. We examined whether preview benefit in a preview search task survived through task-irrelevant changes in the scene, namely a luminance change and the initiation of coherent motion, both occurring in the background. Luminance change of the background disrupted preview benefit if it was synchronized with the onset of the search display. Furthermore, although the presence of coherent background motion per se did not affect preview benefit, its synchronized initiation with the onset of the search display did disrupt preview benefit if the motion speed was sufficiently high. These results suggest that visual marking can be destroyed by a transient event in the scene if that event is sufficiently drastic.

Using the lead vehicle as preview sensor in convoy vehicle active suspension control

NASA Astrophysics Data System (ADS)

Rahman, Mustafizur; Rideout, Geoff

2012-12-01

Both ride quality and roadholding of actively suspended vehicles can be improved by sensing the road ahead of the vehicle and using this information in a preview controller. Previous applications have used look-ahead sensors mounted on the front bumper to measure terrain beneath. Such sensors are vulnerable, potentially confused by water, snow, or other soft obstacles and offer a fixed preview time. For convoy vehicle applications, this paper proposes using the overall response of the preceding vehicle(s) to generate preview controller information for follower vehicles. A robust observer is used to estimate the states of a quarter-car vehicle model, from which road profile is estimated and passed on to the follower vehicle(s) to generate a preview function. The preview-active suspension, implemented in discrete time using a shift register approach to improve simulation time, reduces sprung mass acceleration and dynamic tyre deflection peaks by more than 50% and 40%, respectively. Terrain can change from one vehicle to the next if a loose obstacle is dislodged, or if the vehicle paths are sufficiently different so that one vehicle misses a discrete road event. The resulting spurious preview information can give suspension performance worse than that of a passive or conventional active system. In this paper, each vehicle can effectively estimate the road profile based on its own state trajectory. By comparing its own road estimate with the preview information, preview errors can be detected and suspension control quickly switched from preview to conventional active control to preserve performance improvements compared to passive suspensions.

Parafoveal preview during reading: Effects of sentence position

PubMed Central

White, Sarah J.; Warren, Tessa; Reichle, Erik D.

2011-01-01

Two experiments examined parafoveal preview for words located in the middle of sentences and at sentence boundaries. Parafoveal processing was shown to occur for words at sentence-initial, mid-sentence, and sentence-final positions. Both Experiments 1 and 2 showed reduced effects of preview on regressions out for sentence-initial words. In addition, Experiment 2 showed reduced preview effects on first-pass reading times for sentence-initial words. These effects of sentence position on preview could result from reduced parafoveal processing for sentence-initial words, or other processes specific to word reading at sentence boundaries. In addition to the effects of preview, the experiments also demonstrate variability in the effects of sentence wrap-up on different reading measures, indicating that the presence and time course of wrap-up effects may be modulated by text-specific factors. We also report simulations of Experiment 2 using version 10 of E-Z Reader (Reichle, Warren, & McConnell, 2009), designed to explore the possible mechanisms underlying parafoveal preview at sentence boundaries.

Dissociating parafoveal preview benefit and parafovea-on-fovea effects during reading: A combined eye tracking and EEG study.

PubMed

Niefind, Florian; Dimigen, Olaf

2016-12-01

During reading, the parafoveal processing of an upcoming word n+1 can influence word recognition in two ways: It can affect fixation behavior during the preceding fixation on word n (parafovea-on-fovea effect, POF), and it can facilitate subsequent foveal processing once word n+1 is fixated (preview benefit). While preview benefits are established, evidence for POF effects is mixed. Recently, it has been suggested that POF effects exist, but have a delayed impact on saccade planning and thus coincide with preview benefits measured on word n+1. We combined eye movement and EEG recordings to investigate and separate neural correlates of POF and preview benefit effects. Participants read lists of nouns either in a boundary paradigm or the RSVP-with-flankers paradigm, while we recorded fixation- or event-related potentials (FRPs/ERPs), respectively. The validity and lexical frequency of the word shown as preview for the upcoming word n+1 were orthogonally manipulated. Analyses focused on the first fixation on word n+1. Preview validity (correct vs. incorrect preview) strongly modulated fixation times and electrophysiological N1 amplitudes, replicating previous findings. Importantly, gaze durations and FRPs measured on word n+1 were also affected by the frequency of the word shown as preview, with low-frequency previews eliciting a sustained, N400-like centroparietal negativity. Results support the idea that POF effects exist but affect word recognition with a delay. Lastly, once word n+1 was fixated, its frequency also modulated N1 amplitudes in ERPs and FRPs. Taken together, we separated immediate and delayed effects of parafoveal processing on brain correlates of word recognition. © 2016 Society for Psychophysiological Research.

Trans-saccadic parafoveal preview benefits in fluent reading: a study with fixation-related brain potentials.

PubMed

Dimigen, Olaf; Kliegl, Reinhold; Sommer, Werner

2012-08-01

During natural reading, a parafoveal preview of the upcoming word facilitates its subsequent recognition (e.g., shorter fixation durations compared to masked preview) but nothing is known about the neural correlates of this so-called preview benefit. Furthermore, while the evidence is strong that readers preprocess orthographic features of upcoming words, it is controversial whether word meaning can also be accessed parafoveally. We investigated the timing, scope, and electrophysiological correlates of parafoveal information use in reading by simultaneously recording eye movements and fixation-related brain potentials (FRPs) while participants read word lists fluently from left to right. For one word-the target-(e.g., "blade") parafoveal information was manipulated by showing an identical ("blade"), semantically related ("knife"), or unrelated ("sugar") word as preview. In boundary trials, the preview was shown parafoveally but changed to the correct target word during the incoming saccade. Replicating classic findings, target words were fixated shorter after identical previews. In the EEG, this benefit was reflected in an occipitotemporal preview positivity between 200 and 280 ms. In contrast, there was no facilitation from related previews. In parafoveal-on-foveal trials, preview and target were embedded at neighboring list positions without a display change. Consecutive fixation of two related words produced N400 priming effects, but only shortly (160 ms) after the second word was directly fixated. Results demonstrate that neural responses to words are substantially altered by parafoveal preprocessing under normal reading conditions. We found no evidence that word meaning contributes to these effects. Saccade-contingent display manipulations can be combined with EEG recordings to study extrafoveal perception in vision.

Cooperative global optimal preview tracking control of linear multi-agent systems: an internal model approach

NASA Astrophysics Data System (ADS)

Lu, Yanrong; Liao, Fucheng; Deng, Jiamei; Liu, Huiyang

2017-09-01

This paper investigates the cooperative global optimal preview tracking problem of linear multi-agent systems under the assumption that the output of a leader is a previewable periodic signal and the topology graph contains a directed spanning tree. First, a type of distributed internal model is introduced, and the cooperative preview tracking problem is converted to a global optimal regulation problem of an augmented system. Second, an optimal controller, which can guarantee the asymptotic stability of the augmented system, is obtained by means of the standard linear quadratic optimal preview control theory. Third, on the basis of proving the existence conditions of the controller, sufficient conditions are given for the original problem to be solvable, meanwhile a cooperative global optimal controller with error integral and preview compensation is derived. Finally, the validity of theoretical results is demonstrated by a numerical simulation.

Parafoveal preview benefit in unspaced and spaced Chinese reading.

PubMed

Cui, Lei; Drieghe, Denis; Bai, Xuejun; Yan, Guoli; Liversedge, Simon P

2014-01-01

In an eye movement experiment during reading, we compared parafoveal preview benefit during the reading of Chinese sentences either in the familiar, unspaced format or with spaces inserted between the words. Single-character words or the first of a two-character word were either presented normally or were replaced by a pseudocharacter in the preview. Results indicate that word spacing increased the parafoveal preview benefit but only for the one-character target words. We hypothesized that the incorrect preview of the first character of the two-character word prevented parafoveal processing of the ensuing character(s), effectively nullifying any benefits from the spacing. Our results suggest that word boundary demarcation allows for more precise focusing of attention.

Measuring Memory and Attention to Preview in Motion.

Objective Use perceptual-motor responses to perturbations to reveal the spatio-temporal detail of memory for the recent past and attention to preview when participants track a winding roadway. Background Memory of the recently passed roadway can be inferred from feedback control models of the participants' manual movement patterns. Similarly, attention to preview of the upcoming roadway can be inferred from feedforward control models of manual movement patterns. Method Perturbation techniques were used to measure these memory and attention functions. Results In a laboratory tracking task, the bandwidth of lateral roadway deviations was found to primarily influence memory for the past roadway rather than attention to preview. A secondary auditory/verbal/vocal memory task resulted in higher velocity error and acceleration error in the tracking task but did not affect attention to preview. Attention to preview was affected by the frequency pattern of sinusoidal perturbations of the roadway. Conclusion Perturbation techniques permit measurement of the spatio-temporal span of memory and attention to preview that affect tracking a winding roadway. They also provide new ways to explore goal-directed forgetting and spatially distributed attention in the context of movement. More generally, these techniques provide sensitive measures of individual differences in cognitive aspects of action. Application Models of driving behavior and assessment of driving skill may benefit from more detailed spatio-temporal measurement of attention to preview.

This study examined the role of route previewing strategies on climbing fluency and on exploratory movements of the limbs, in order to understand whether previewing helps people to perceive and to realize affordances. Eight inexperienced and ten experienced climbers previewed a 10 m high route of 5b difficulty on French scale, then climbed it with a top-rope as fluently as possible. Gaze behavior was collected from an eye tracking system during the preview and allowed us to determine the number of times they scanned the route, and which of four route previewing strategies (fragmentary, ascending, zigzagging, and sequence-of-blocks) they used. Five inertial measurement units (IMU) (3D accelerometer, 3D gyroscope, 3D magnetometer) were attached to the hip, both feet, and forearms to analyze the vertical acceleration and direction of each limb and hip during the ascent. We were able to detect movement and immobility phases of each IMU using segmentation and classification processes. Depending on whether the limbs and/or hip were moving, five states of behavior were detected: immobility, postural regulation, hold exploration, hold change, and hold traction. Using cluster analysis we identified four clusters of gaze behavior during route previewing depending on route preview duration, number of scan paths, fixations duration, ascending, zigzagging, and sequence-of-blocks strategies. The number of scan paths was positively correlated with relative duration of exploration and negatively correlated with relative duration of hold changes during the ascent. Additionally, a high relative duration of sequence-of-blocks strategy and zigzagging strategy were associated with a high relative duration of immobility during the ascent. Route previewing might help to pick up functional information about reachable, graspable, and usable holds, in order to chain movements together and to find the route. In other words, route previewing might contribute to perceiving and realizing nested affordances.

Coordination of Word Recognition and Oculomotor Control During Reading: The Role of Implicit Lexical Decisions

PubMed Central

Choi, Wonil; Gordon, Peter C.

2013-01-01

The coordination of word-recognition and oculomotor processes during reading was evaluated in two eye-tracking experiments that examined how word skipping, where a word is not fixated during first-pass reading, is affected by the lexical status of a letter string in the parafovea and ease of recognizing that string. Ease of lexical recognition was manipulated through target-word frequency (Experiment 1) and through repetition priming between prime-target pairs embedded in a sentence (Experiment 2). Using the gaze-contingent boundary technique the target word appeared in the parafovea either with full preview or with transposed-letter (TL) preview. The TL preview strings were nonwords in Experiment 1 (e.g., bilnk created from the target blink), but were words in Experiment 2 (e.g., sacred created from the target scared). Experiment 1 showed greater skipping for high-frequency than low-frequency target words in the full preview condition but not in the TL preview (nonword) condition. Experiment 2 showed greater skipping for target words that repeated an earlier prime word than for those that did not, with this repetition priming occurring both with preview of the full target and with preview of the target’s TL neighbor word. However, time to progress from the word after the target was greater following skips of the TL preview word, whose meaning was anomalous in the sentence context, than following skips of the full preview word whose meaning fit sensibly into the sentence context. Together, the results support the idea that coordination between word-recognition and oculomotor processes occurs at the level of implicit lexical decisions. PMID:23106372

Semantic parafoveal-on-foveal effects and preview benefits in reading: Evidence from Fixation Related Potentials.

PubMed

López-Peréz, P J; Dampuré, J; Hernández-Cabrera, J A; Barber, H A

2016-11-01

During reading parafoveal information can affect the processing of the word currently fixated (parafovea-on-fovea effect) and words perceived parafoveally can facilitate their subsequent processing when they are fixated on (preview effect). We investigated parafoveal processing by simultaneously recording eye movements and EEG measures. Participants read word pairs that could be semantically associated or not. Additionally, the boundary paradigm allowed us to carry out the same manipulation on parafoveal previews that were displayed until reader's gaze moved to the target words. Event Related Potentials time-locked to the prime-preview presentation showed a parafoveal-on-foveal N400 effect. Fixation Related Potentials time locked to the saccade offset showed an N400 effect related to the prime-target relationship. Furthermore, this later effect interacted with the semantic manipulation of the previews, supporting a semantic preview benefit. These results demonstrate that at least under optimal conditions foveal and parafoveal information can be simultaneously processed and integrated. Copyright © 2016 Elsevier Inc. All rights reserved.

Subset selective search on the basis of color and preview.

PubMed

Donk, Mieke

2017-01-01

In the preview paradigm observers are presented with one set of elements (the irrelevant set) followed by the addition of a second set among which the target is presented (the relevant set). Search efficiency in such a preview condition has been demonstrated to be higher than that in a full-baseline condition in which both sets are simultaneously presented, suggesting that a preview of the irrelevant set reduces its influence on the search process. However, numbers of irrelevant and relevant elements are typically not independently manipulated. Moreover, subset selective search also occurs when both sets are presented simultaneously but differ in color. The aim of the present study was to investigate how numbers of irrelevant and relevant elements contribute to preview search in the absence and presence of a color difference between subsets. In two experiments it was demonstrated that a preview reduced the influence of the number of irrelevant elements in the absence but not in the presence of a color difference between subsets. In the presence of a color difference, a preview lowered the effect of the number of relevant elements but only when the target was defined by a unique feature within the relevant set (Experiment 1); when the target was defined by a conjunction of features (Experiment 2), search efficiency as a function of the number of relevant elements was not modulated by a preview. Together the results are in line with the idea that subset selective search is based on different simultaneously operating mechanisms.

Extrafoveal preview benefit during free-viewing visual search in the monkey

PubMed Central

Krishna, B. Suresh; Ipata, Anna E.; Bisley, James W.; Gottlieb, Jacqueline; Goldberg, Michael E.

2014-01-01

Abstract Previous studies have shown that subjects require less time to process a stimulus at the fovea after a saccade if they have viewed the same stimulus in the periphery immediately prior to the saccade. This extrafoveal preview benefit indicates that information about the visual form of an extrafoveally viewed stimulus can be transferred across a saccade. Here, we extend these findings by demonstrating and characterizing a similar extrafoveal preview benefit in monkeys during a free-viewing visual search task. We trained two monkeys to report the orientation of a target among distractors by releasing one of two bars with their hand; monkeys were free to move their eyes during the task. Both monkeys took less time to indicate the orientation of the target after foveating it, when the target lay closer to the fovea during the previous fixation. An extrafoveal preview benefit emerged even if there was more than one intervening saccade between the preview and the target fixation, indicating that information about target identity could be transferred across more than one saccade and could be obtained even if the search target was not the goal of the next saccade. An extrafoveal preview benefit was also found for distractor stimuli. These results aid future physiological investigations of the extrafoveal preview benefit. PMID:24403392

Parafoveal preview benefit in reading is only obtained from the saccade goal.

PubMed

McDonald, Scott A

2006-12-01

Previous research has demonstrated that reading is less efficient when parafoveal visual information about upcoming words is invalid or unavailable; the benefit from a valid preview is realised as reduced reading times on the subsequently foveated word, and has been explained with reference to the allocation of attentional resources to parafoveal word(s). This paper presents eyetracking evidence that preview benefit is obtained only for words that are selected as the saccade target. Using a gaze-contingent display change paradigm (Rayner, K. (1975). The perceptual span and peripheral cues in reading. Cognitive Psychology, 7, 65-81), the position of the triggering boundary was set near the middle of the pretarget word. When a refixation saccade took the eye across the boundary in the pretarget word, there was no reliable effect of the validity of the target word preview. However, when the triggering boundary was positioned just after the pretarget word, a robust preview benefit was observed, replicating previous research. The current results complement findings from studies of basic visual function, suggesting that for the case of preview benefit in reading, attentional and oculomotor processes are obligatorily coupled.

-The Influence of Scene Context on Parafoveal Processing of Objects.

PubMed

Castelhano, Monica S; Pereira, Effie J

2017-04-21

Many studies in reading have shown the enhancing effect of context on the processing of a word before it is directly fixated (parafoveal processing of words; Balota et al., 1985; Balota & Rayner, 1983; Ehrlich & Rayner, 1981). Here, we examined whether scene context influences the parafoveal processing of objects and enhances the extraction of object information. Using a modified boundary paradigm (Rayner, 1975), the Dot-Boundary paradigm, participants fixated on a suddenly-onsetting cue before the preview object would onset 4° away. The preview object could be identical to the target, visually similar, visually dissimilar, or a control (black rectangle). The preview changed to the target object once a saccade toward the object was made. Critically, the objects were presented on either a consistent or an inconsistent scene background. Results revealed that there was a greater processing benefit for consistent than inconsistent scene backgrounds and that identical and visually similar previews produced greater processing benefits than other previews. In the second experiment, we added an additional context condition in which the target location was inconsistent, but the scene semantics remained consistent. We found that changing the location of the target object disrupted the processing benefit derived from the consistent context. Most importantly, across both experiments, the effect of preview was not enhanced by scene context. Thus, preview information and scene context appear to independently boost the parafoveal processing of objects without any interaction from object-scene congruency.

2017-05-01

Human computer interfaces make computational science more comprehensible and impactful. Complex 3D structures such as proteins or DNA are magnified by digital representations and displayed on two-dimensional monitors. Augmented reality has recently opened another door to access the virtual three-dimensional world. Herein, we present an augmented reality application called ChemPreview with the potential to manipulate bio-molecular structures at an atomistic level. ChemPreview is available at https://github.com/wallerlab/chem-preview/releases, and is built on top of the Meta 1 platform https://www.metavision.com/. ChemPreview can be used to interact with a protein in an intuitive way using natural hand gestures, thereby making it appealing to computational chemists or structural biologists. The ability to manipulate atoms in real world could eventually provide new and more efficient ways of extracting structural knowledge, or designing new molecules in silico.

2017-08-01

Optoelectronic Instruments is a comprehensive professional course for senior students majored in optical engineering and similar specialties. Due to the low lecturer/ student ratio, typically less than 1:100, most of the students gave up the chance of one-to-one communication with the lecturers even when they were confused about the principle or applications of the instruments. A smart phone App Rain Classroom associated with messaging App Wechat is introduced. It enables the lecturers to receive instant feedback from students through bullet screen, push preview and review materials and post in-class quiz. Investigation also shows that 76% of the students enjoyed the new interactive tool, acknowledging its help in understanding the topic better, improving in-class interaction, and after class communications.

Parafoveal processing during reading is reduced across a morphological boundary

Drieghe, Denis; Pollatsek, Alexander; Juhasz, Barbara J.; Rayner, Keith

2010-01-01

A boundary change manipulation was implemented within a monomorphemic word (e.g., fountaom as a preview for fountain), where parallel processing should occur given adequate visual acuity, and within an unspaced compound (bathroan as a preview for bathroom), where some serial processing of the constituents is likely. Consistent with that hypothesis, there was no effect of the preview manipulation on fixation time on the 1st constituent of the compound, whereas there was on the corresponding letters of the monomorphemic word. There was also a larger preview disruption on gaze duration on the whole monomorphemic word than on the compound, suggesting more parallel processing within monomorphemic words. PMID:20409538

Cosmic Times is a series of curriculum support materials and classroom activities for upper middle school and high school students which teach the nature of science by exploring the history of our understanding of the universe during the past 100 years. Starting with the confirmation of Einstein's theory of gravity in 1919 to the current conundrum posed by the discovery of dark energy, Cosmic Times examines the discoveries, the theories, and the people involved in this changing [understanding] of the universe. Cosmic Times takes the form of 6 posters, each resembling the front page of a newspaper from a particular time in this history with articles describing the discoveries. Each poster is accompanied by 4-5 classroom lessons which enable students to examine the science concepts behind the discoveries, develop techniques to improve science literacy, and investigate the nature of science using historical examples. Cosmic Times directly connects with the IYA theme of Astronomy in the Classroom, as well as the general theme of the impact of astronomy history. Cosmic Times has been developed with a freelance writer to write the articles for the posters, a group of teachers to develop the lessons, and evaluator to provide testing of the materials with a group of rural teachers in underserved communities. This poster presentation previews the Cosmic Times materials, which are posted on http://cosmictimes.gsfc.nasa.gov/ as they become available. Cosmic Times is funded in part via a NASA IDEAS grant.

Parafoveal processing in silent and oral reading: Reading mode influences the relative weighting of phonological and semantic information in Chinese.

PubMed

Pan, Jinger; Laubrock, Jochen; Yan, Ming

2016-08-01

We examined how reading mode (i.e., silent vs. oral reading) influences parafoveal semantic and phonological processing during the reading of Chinese sentences, using the gaze-contingent boundary paradigm. In silent reading, we found in 2 experiments that reading times on target words were shortened with semantic previews in early and late processing, whereas phonological preview effects mainly occurred in gaze duration or second-pass reading. In contrast, results showed that phonological preview information is obtained early on in oral reading. Strikingly, in oral reading, we observed a semantic preview cost on the target word in Experiment 1 and a decrease in the effect size of preview benefit from first- to second-pass measures in Experiment 2, which we hypothesize to result from increased preview duration. Taken together, our results indicate that parafoveal semantic information can be obtained irrespective of reading mode, whereas readers more efficiently process parafoveal phonological information in oral reading. We discuss implications for notions of information processing priority and saccade generation during silent and oral reading. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

The effect of contextual constraint on parafoveal processing in reading

PubMed Central

Schotter, Elizabeth R.; Lee, Michelle; Reiderman, Michael; Rayner, Keith

2015-01-01

Semantic preview benefit in reading is an elusive and controversial effect because empirical studies do not always (but sometimes) find evidence for it. Its presence seems to depend on (at least) the language being read, visual properties of the text (e.g., initial letter capitalization), the type of relationship between preview and target, and as shown here, semantic constraint generated by the prior sentence context. Schotter (2013) reported semantic preview benefit for synonyms, but not semantic associates when the preview/target was embedded in a neutral sentence context. In Experiment 1, we embedded those same previews/targets into constrained sentence contexts and in Experiment 2 we replicated the effects reported by Schotter (2013; in neutral sentence contexts) and Experiment 1 (in constrained contexts) in a within-subjects design. In both experiments, we found an early (i.e., first-pass) apparent preview benefit for semantically associated previews in constrained contexts that went away in late measures (e.g., total time). These data suggest that sentence constraint (at least as manipulated in the current study) does not operate by making a single word form expected, but rather generates expectations about what kinds of words are likely to appear. Furthermore, these data are compatible with the assumption of the E-Z Reader model that early oculomotor decisions reflect “hedged bets” that a word will be identifiable and, when wrong, lead the system to identify the wrong word, triggering regressions.

Cross-language parafoveal semantic processing: Evidence from Korean-Chinese bilinguals.

Wang, Aiping; Yeon, Junmo; Zhou, Wei; Shu, Hua; Yan, Ming

2016-02-01

In the present study, we aimed at testing cross-language cognate and semantic preview effects. We tested how native Korean readers who learned Chinese as a second language make use of the parafoveal information during the reading of Chinese sentences. There were 3 types of Korean preview words: cognate translations of the Chinese target words, semantically related noncognate words, and unrelated words. Together with a highly significant cognate preview effect, more critically, we also observed reliable facilitation in processing of the target word from the semantically related previews in all fixation measures. Results from the present study provide first evidence for semantic processing from parafoveally presented Korean words and for cross-language parafoveal semantic processing.

Too little or too much? Parafoveal preview benefits and parafoveal load costs in dyslexic adults.

PubMed

Silva, Susana; Faísca, Luís; Araújo, Susana; Casaca, Luis; Carvalho, Loide; Petersson, Karl Magnus; Reis, Alexandra

2016-07-01

Two different forms of parafoveal dysfunction have been hypothesized as core deficits of dyslexic individuals: reduced parafoveal preview benefits ("too little parafovea") and increased costs of parafoveal load ("too much parafovea"). We tested both hypotheses in a single eye-tracking experiment using a modified serial rapid automatized naming (RAN) task. Comparisons between dyslexic and non-dyslexic adults showed reduced parafoveal preview benefits in dyslexics, without increased costs of parafoveal load. Reduced parafoveal preview benefits were observed in a naming task, but not in a silent letter-finding task, indicating that the parafoveal dysfunction may be consequent to the overload with extracting phonological information from orthographic input. Our results suggest that dyslexics' parafoveal dysfunction is not based on strict visuo-attentional factors, but nevertheless they stress the importance of extra-phonological processing. Furthermore, evidence of reduced parafoveal preview benefits in dyslexia may help understand why serial RAN is an important reading predictor in adulthood.

Third and fifth graders' processing of parafoveal information in reading: A study in single-word recognition.

PubMed

Khelifi, Rachid; Sparrow, Laurent; Casalis, Séverine

2015-11-01

We assessed third and fifth graders' processing of parafoveal word information using a lexical decision task. On each trial, a preview word was first briefly presented parafoveally in the left or right visual field before a target word was displayed. Preview and target words could be identical, share the first three letters, or have no letters in common. Experiment 1 showed that developing readers receive the same word recognition benefit from parafoveal previews as expert readers. The impact of a change of case between preview and target in Experiment 2 showed that in all groups of readers, the preview benefit resulted from the identification of letters at an abstract level rather than from facilitation at a purely visual level. Fifth graders identified more letters from the preview than third graders. The results are interpreted within the framework of the interactive activation model. In particular, we suggest that although the processing of parafoveal information led to letter identification in developing readers, the processes involved may differ from those in expert readers. Although expert readers' processing of parafoveal information led to activation at the level of lexical representations, no such activation was observed in developing readers.

Visual working memory simultaneously guides facilitation and inhibition during visual search.

PubMed

Dube, Blaire; Basciano, April; Emrich, Stephen M; Al-Aidroos, Naseem

2016-07-01

During visual search, visual working memory (VWM) supports the guidance of attention in two ways: It stores the identity of the search target, facilitating the selection of matching stimuli in the search array, and it maintains a record of the distractors processed during search so that they can be inhibited. In two experiments, we investigated whether the full contents of VWM can be used to support both of these abilities simultaneously. In Experiment 1, participants completed a preview search task in which (a) a subset of search distractors appeared before the remainder of the search items, affording participants the opportunity to inhibit them, and (b) the search target varied from trial to trial, requiring the search target template to be maintained in VWM. We observed the established signature of VWM-based inhibition-reduced ability to ignore previewed distractors when the number of distractors exceeds VWM's capacity-suggesting that VWM can serve this role while also representing the target template. In Experiment 2, we replicated Experiment 1, but added to the search displays a singleton distractor that sometimes matched the color (a task-irrelevant feature) of the search target, to evaluate capture. We again observed the signature of VWM-based preview inhibition along with attentional capture by (and, thus, facilitation of) singletons matching the target template. These findings indicate that more than one VWM representation can bias attention at a time, and that these representations can separately affect selection through either facilitation or inhibition, placing constraints on existing models of the VWM-based guidance of attention.

Müller-Lyer figures influence the online reorganization of visually guided grasping movements.

PubMed

Heath, Matthew; Rival, Christina; Neely, Kristina; Krigolson, Olav

2006-03-01

In advance of grasping a visual object embedded within fins-in and fins-out Müller-Lyer (ML) configurations, participants formulated a premovement grip aperture (GA) based on the size of a neutral preview object. Preview objects were smaller, veridical, or larger than the size of the to-be-grasped target object. As a result, premovement GA associated with the small and large preview objects required significant online reorganization to appropriately grasp the target object. We reasoned that such a manipulation would provide an opportunity to examine the extent to which the visuomotor system engages egocentric and/or allocentric visual cues for the online, feedback-based control of action. It was found that the online reorganization of GA was reliably influenced by the ML figures (i.e., from 20 to 80% of movement time), regardless of the size of the preview object, albeit the small and large preview objects elicited more robust illusory effects than the veridical preview object. These results counter the view that online grasping control is mediated by absolute visual information computed with respect to the observer (e.g., Glover in Behav Brain Sci 27:3-78, 2004; Milner and Goodale in The visual brain in action 1995). Instead, the impact of the ML figures suggests a level of interaction between egocentric and allocentric visual cues in online action control.

Is orthographic information from multiple parafoveal words processed in parallel: An eye-tracking study.

PubMed

Cutter, Michael G; Drieghe, Denis; Liversedge, Simon P

2017-08-01

In the current study we investigated whether orthographic information available from 1 upcoming parafoveal word influences the processing of another parafoveal word. Across 2 experiments we used the boundary paradigm (Rayner, 1975) to present participants with an identity preview of the 2 words after the boundary (e.g., hot pan ), a preview in which 2 letters were transposed between these words (e.g., hop tan ), or a preview in which the same 2 letters were substituted (e.g., hob fan ). We hypothesized that if these 2 words were processed in parallel in the parafovea then we may observe significant preview benefits for the condition in which the letters were transposed between words relative to the condition in which the letters were substituted. However, no such effect was observed, with participants fixating the words for the same amount of time in both conditions. This was the case both when the transposition was made between the final and first letter of the 2 words (e.g., hop tan as a preview of hot pan ; Experiment 1) and when the transposition maintained within word letter position (e.g., pit hop as a preview of hit pop ; Experiment 2). The implications of these findings are considered in relation to serial and parallel lexical processing during reading. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Processing the in the parafovea: are articles skipped automatically?

PubMed

Angele, Bernhard; Rayner, Keith

2013-03-01

One of the words that readers of English skip most often is the definite article the. Most accounts of reading assume that in order for a reader to skip a word, it must have received some lexical processing. The definite article is skipped so regularly, however, that the oculomotor system might have learned to skip the letter string t-h-e automatically. We tested whether skipping of articles in English is sensitive to context information or whether it is truly automatic in the sense that any occurrence of the letter string the will trigger a skip. This was done using the gaze-contingent boundary paradigm (Rayner, 1975) to provide readers with false parafoveal previews of the article the. All experimental sentences contained a short target verb, the preview of which could be correct (i.e., identical to the actual subsequent word in the sentence; e.g., ace), a nonword (tda), or an infelicitous article preview (the). Our results indicated that readers tended to skip the infelicitous the previews frequently, suggesting that, in many cases, they seemed to be unable to detect the syntactic anomaly in the preview and based their skipping decision solely on the orthographic properties of the article. However, there was some evidence that readers sometimes detected the anomaly, as they also showed increased skipping of the pretarget word in the the preview condition.

Distinct subsystems for the parafoveal processing of spatial and linguistic information during eye fixations in reading.

Inhoff, Albrecht W; Radach, Ralph; Eiter, Brianna M; Juhasz, Barbara

2003-07-01

Two experiments examined readers' use of parafoveally obtained word length information for word recognition. Both experiments manipulated the length (number of constituent characters) of a parafoveally previewed target word so that it was either accurately or inaccurately specified. In Experiment 1, previews also either revealed or denied useful orthographic information. In Experiment 2, parafoveal targets were either high- or low-frequency words. Eye movement contingent display changes were used to show the intact target upon its fixation. Examination of target viewing duration showed completely additive effects of word length previews and of ortho-graphic previews in Experiment 1, viewing duration being shorter in the accurate-length and the orthographic preview conditions. Experiment 2 showed completely additive effects of word length and word frequency, target viewing being shorter in the accurate-length and the high-frequency conditions. Together these results indicate that functionally distinct subsystems control the use of parafoveally visible spatial and linguistic information in reading. Parafoveally visible spatial information appears to be used for two distinct extralinguistic computations: visual object selection and saccade specification.

Visuospatial working memory mediates inhibitory and facilitatory guidance in preview search.

PubMed

Barrett, Doug J K; Shimozaki, Steven S; Jensen, Silke; Zobay, Oliver

2016-10-01

Visual search is faster and more accurate when a subset of distractors is presented before the display containing the target. This "preview benefit" has been attributed to separate inhibitory and facilitatory guidance mechanisms during search. In the preview task the temporal cues thought to elicit inhibition and facilitation provide complementary sources of information about the likely location of the target. In this study, we use a Bayesian observer model to compare sensitivity when the temporal cues eliciting inhibition and facilitation produce complementary, and competing, sources of information. Observers searched for T-shaped targets among L-shaped distractors in 2 standard and 2 preview conditions. In the standard conditions, all the objects in the display appeared at the same time. In the preview conditions, the initial subset of distractors either stayed on the screen or disappeared before the onset of the search display, which contained the target when present. In the latter, the synchronous onset of old and new objects negates the predictive utility of stimulus-driven capture during search. The results indicate observers combine memory-driven inhibition and sensory-driven capture to reduce spatial uncertainty about the target's likely location during search. In the absence of spatially predictive onsets, memory-driven inhibition at old locations persists despite irrelevant sensory change at previewed locations. This result is consistent with a bias toward unattended objects during search via the active suppression of irrelevant capture at previously attended locations.

Visual search guidance is best after a short delay

PubMed Central

Schmidt, Joseph; Zelinsky, Gregory J.

2011-01-01

Search displays are typically presented immediately after a target cue, but in the real-world, delays often exist between target designation and search. Experiments 1 and 2 asked how search guidance changes with delay. Targets were cued using a picture or text label, each for 3000ms, followed by a delay up to 9000ms before the search display. Search stimuli were realistic objects, and guidance was quantified using multiple eye movement measures. Text-based cues showed a non-significant trend towards greater guidance following any delay relative to a no-delay condition. However, guidance from a pictorial cue increased sharply 300–600 msec after preview offset. Experiment 3 replicated this guidance enhancement using shorter preview durations while equating the time from cue onset to search onset, demonstrating that the guidance benefit is linked to preview offset rather than a more complete encoding of the target. Experiment 4 showed that enhanced guidance persists even with a mask flashed at preview offset, suggesting an explanation other than visual priming. We interpret our findings as evidence for the rapid consolidation of target information into a guiding representation, which attains its maximum effectiveness shortly after preview offset.

Design of an optimal preview controller for linear discrete-time descriptor systems with state delay

NASA Astrophysics Data System (ADS)

Cao, Mengjuan; Liao, Fucheng

2015-04-01

In this paper, the linear discrete-time descriptor system with state delay is studied, and a design method for an optimal preview controller is proposed. First, by using the discrete lifting technique, the original system is transformed into a general descriptor system without state delay in form. Then, taking advantage of the first-order forward difference operator, we construct a descriptor augmented error system, including the state vectors of the lifted system, error vectors, and desired target signals. Rigorous mathematical proofs are given for the regularity, stabilisability, causal controllability, and causal observability of the descriptor augmented error system. Based on these, the optimal preview controller with preview feedforward compensation for the original system is obtained by using the standard optimal regulator theory of the descriptor system. The effectiveness of the proposed method is shown by numerical simulation.

Capturing the complexity: Content, type, and amount of instruction and quality of the classroom learning environment synergistically predict third graders’ vocabulary and reading comprehension outcomes

2014-01-01

We examined classrooms as complex systems that affect students’ literacy learning through interacting effects of content and amount of time individual students spent in literacy instruction along with the global quality of the classroom-learning environment. We observed 27 third grade classrooms serving 315 target students using two different observation systems. The first assessed instruction at a more micro-level; specifically, the amount of time individual students spent in literacy instruction defined by the type of instruction, role of the teacher, and content. The second assessed the quality of the classroom-learning environment at a more macro level focusing on classroom organization, teacher responsiveness, and support for vocabulary and language. Results revealed that both global quality of the classroom learning environment and time individual students spent in specific types of literacy instruction covering specific content interacted to predict students’ comprehension and vocabulary gains whereas neither system alone did. These findings support a dynamic systems model of how individual children learn in the context of classroom literacy instruction and the classroom-learning environment, which can help to improve observations systems, advance research, elevate teacher evaluation and professional development, and enhance student achievement.

Optimal preview control for a linear continuous-time stochastic control system in finite-time horizon

NASA Astrophysics Data System (ADS)

Wu, Jiang; Liao, Fucheng; Tomizuka, Masayoshi

2017-01-01

This paper discusses the design of the optimal preview controller for a linear continuous-time stochastic control system in finite-time horizon, using the method of augmented error system. First, an assistant system is introduced for state shifting. Then, in order to overcome the difficulty of the state equation of the stochastic control system being unable to be differentiated because of Brownian motion, the integrator is introduced. Thus, the augmented error system which contains the integrator vector, control input, reference signal, error vector and state of the system is reconstructed. This leads to the tracking problem of the optimal preview control of the linear stochastic control system being transformed into the optimal output tracking problem of the augmented error system. With the method of dynamic programming in the theory of stochastic control, the optimal controller with previewable signals of the augmented error system being equal to the controller of the original system is obtained. Finally, numerical simulations show the effectiveness of the controller.

The influence of visual contrast and case changes on parafoveal preview benefits during reading.

PubMed

Wang, Chin-An; Inhoff, Albrecht W

2010-04-01

Reingold and Rayner (2006) showed that the visual contrast of a fixated target word influenced its viewing duration, but not the viewing of the next (posttarget) word in the text that was shown in regular contrast. Configurational target changes, by contrast, influenced target and posttarget viewing. The current study examined whether this effect pattern can be attributed to differential processing of the posttarget word during target viewing. A boundary paradigm (Rayner, 1975) was used to provide an informative or uninformative posttarget preview and to reveal the word when it was fixated. Consistent with the earlier study, more time was spent viewing the target when its visual contrast was low and its configuration unfamiliar. Critically, target contrast had no effect on the acquisition of useful information from a posttarget preview, but an unfamiliar target configuration diminished the usefulness of an informative posttarget preview. These findings are consistent with Reingold and Rayner's (2006) claim that saccade programming and attention shifting during reading can be controlled by functionally distinct word recognition processes.

Real-world visual search is dominated by top-down guidance.

PubMed

Chen, Xin; Zelinsky, Gregory J

2006-11-01

How do bottom-up and top-down guidance signals combine to guide search behavior? Observers searched for a target either with or without a preview (top-down manipulation) or a color singleton (bottom-up manipulation) among the display objects. With a preview, reaction times were faster and more initial eye movements were guided to the target; the singleton failed to attract initial saccades under these conditions. Only in the absence of a preview did subjects preferentially fixate the color singleton. We conclude that the search for realistic objects is guided primarily by top-down control. Implications for saliency map models of visual search are discussed.

2005-07-01

There are growing needs for quick preview of video contents for the purpose of improving accessibility of video archives as well as reducing network traffics. In this paper, a storyboard that contains a user-specified number of keyframes is produced from a given video sequence. It is based on hierarchical cluster analysis of feature vectors that are derived from wavelet coefficients of video frames. Consistent use of extracted feature vectors is the key to avoid a repetition of computationally-intensive parsing of the same video sequence. Experimental results suggest that a significant reduction in computational time is gained by this strategy.

Looking at practice: revealing the knowledge demands of teaching data handling in the primary classroom

NASA Astrophysics Data System (ADS)

Leavy, Aisling

2015-09-01

In the evolving field of mathematics education, there is the need to maintain the relationship between what is presented in college level preparation courses and the skills required to teach mathematics in classrooms. This research examines the knowledge demands placed on 73 pre-service primary teachers as they use lesson study to plan and teach data handling in primary classrooms. Pre-service teachers are observed as they plan, teach and re-teach data lessons in classrooms. Problems of practice are identified and categorized using the Ball, Thames and Phelps (2008) subdomains of common content knowledge (CCK), specialized content knowledge (SCK), knowledge of content and students (KCS) and knowledge of content and teaching (KCT). The results provide insights into the specific knowledge demands placed on early career teachers when teaching data and statistics and identifies foci area that can be addressed in teacher preparation programs. The results illustrate that development of understandings in one knowledge subdomain can motivate and impact learning in another subdomain. These interrelationships were found to exist both within and between the domains of content and pedagogical content knowledge.

Words, shape, visual search and visual working memory in 3-year-old children.

PubMed

Vales, Catarina; Smith, Linda B

2015-01-01

Do words cue children's visual attention, and if so, what are the relevant mechanisms? Across four experiments, 3-year-old children (N = 163) were tested in visual search tasks in which targets were cued with only a visual preview versus a visual preview and a spoken name. The experiments were designed to determine whether labels facilitated search times and to examine one route through which labels could have their effect: By influencing the visual working memory representation of the target. The targets and distractors were pictures of instances of basic-level known categories and the labels were the common name for the target category. We predicted that the label would enhance the visual working memory representation of the target object, guiding attention to objects that better matched the target representation. Experiments 1 and 2 used conjunctive search tasks, and Experiment 3 varied shape discriminability between targets and distractors. Experiment 4 compared the effects of labels to repeated presentations of the visual target, which should also influence the working memory representation of the target. The overall pattern fits contemporary theories of how the contents of visual working memory interact with visual search and attention, and shows that even in very young children heard words affect the processing of visual information. © 2014 John Wiley & Sons Ltd.

Swindle, Taren M; Ward, Wendy L; Whiteside-Mansell, Leanne

2018-01-01

This study investigated the use of Facebook to deliver health-related education materials to augment a preschool classroom-based obesity prevention curriculum. Cross-sectional, mixed methods (descriptive and interviews). Head Start classrooms administered by 2 large agencies (1 rural and 1 urban). Convenience sample of parents in 13 classrooms (cohort 1, 3 classrooms; cohort 2, 10 classrooms). Delivery of nutrition education curriculum content using social media (Facebook). Qualitative interviews assessed barriers and facilitators to Facebook use. Parent views, likes, and comments were measured to reflect parent engagement with Facebook. Content analyses (qualitative data) and descriptive statistics (quantitative data). Family access (views) and interaction (comments and likes) with the posts varied based on type and content of posts. Rural families were more active. Barriers to parental Facebook engagement included a desire to see more posts from classroom teachers, lack of time, and misunderstanding about privacy protections. Facilitators of parental Facebook engagement included perceived utility of the content and social support. Facebook was found to be a feasible platform to provide nutrition education and facilitated varying levels of parental engagement. Lessons learned and implications for prevention and intervention programming are offered. Copyright © 2017 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

No differences in grades or level of satisfaction in a flipped classroom for neuroanatomy.

PubMed

Whillier, Stephney; Lystad, Reidar Petter

2015-10-01

The intensive nature of a 5- or 6-week teaching block poses unique problems for adequate delivery of content. This study was designed to compare the delivery of a unit of undergraduate neuroanatomy in a short summer school period, as a traditionally taught unit, with a rendition given in the form of the "Flipped Classroom." The aim was to evaluate the effectiveness of the flipped classroom in the intensive mode classroom. The flipped classroom encompassed the same learning outcomes, but students were responsible for covering the content at home in preparation for tutorials that applied their acquired knowledge to higher levels of thinking. The main outcome measures were the final course grades and the level of satisfaction with the course. There were no significant differences between the 2 cohorts in final grades (p = .259), self-rated knowledge (p = .182), or overall satisfaction with the course (p = .892). This particular design of the flipped classroom did not add value to the intensive mode experience. It may be that this mode of delivery is ill suited to intensive classes for subjects that carry a lot of content. The use of the flipped classroom requires further research to fully evaluate its value.

Flexible Feature-Based Inhibition in Visual Search Mediates Magnified Impairments of Selection: Evidence from Carry-Over Effects under Dynamic Preview-Search Conditions

Is attention confined to one word at a time? The spatial distribution of parafoveal preview benefits during reading.

PubMed

Wang, Chin-An; Inhoff, Albrecht W; Radach, Ralph

2009-10-01

Eye movements were recorded while participants read declarative sentences. Each sentence contained a critical three-word sequence with a three-letter target word (n), a spatially adjacent post-target word (n+1), and a subsequent nonadjacent post-target word (n+2). The parafoveal previews of words n and n+2 were manipulated so that they were either fully visible or masked until they were fixated. The results revealed longer word n and word n+1 viewing durations when word n had been masked in the parafovea, and this occurred irrespective of whether the target was skipped or fixated. Furthermore, masking of word n diminished the usefulness of the preview of word n+2. These results indicate that the effect of a parafoveally available target preview was not strictly localized. Instead, it influenced target viewing and the viewing of the two subsequent words in the text. These results are difficult to reconcile with the assumption that attention is confined to one word at a time until that word is recognized and that attention is then shifted from the recognized word to the next.

Direct lexical control of eye movements in reading: Evidence from a survival analysis of fixation durations

PubMed Central

Reingold, Eyal M.; Reichle, Erik D.; Glaholt, Mackenzie G.; Sheridan, Heather

2013-01-01

Participants’ eye movements were monitored in an experiment that manipulated the frequency of target words (high vs. low) as well as their availability for parafoveal processing during fixations on the pre-target word (valid vs. invalid preview). The influence of the word-frequency by preview validity manipulation on the distributions of first fixation duration was examined by using ex-Gaussian fitting as well as a novel survival analysis technique which provided precise estimates of the timing of the first discernible influence of word frequency on first fixation duration. Using this technique, we found a significant influence of word frequency on fixation duration in normal reading (valid preview) as early as 145 ms from the start of fixation. We also demonstrated an equally rapid non-lexical influence on first fixation duration as a function of initial landing position (location) on target words. The time-course of frequency effects, but not location effects was strongly influenced by preview validity, demonstrating the crucial role of parafoveal processing in enabling direct lexical control of reading fixation times. Implications for models of eye-movement control are discussed. PMID:22542804

Generalized pipeline for preview and rendering of synthetic holograms

NASA Astrophysics Data System (ADS)

Pappu, Ravikanth; Sparrell, Carlton J.; Underkoffler, John S.; Kropp, Adam B.; Chen, Benjie; Plesniak, Wendy J.

1997-04-01

We describe a general pipeline for the computation and display of either fully-computed holograms or holographic stereograms using the same 3D database. A rendering previewer on a Silicon Graphics Onyx allows a user to specify viewing geometry, database transformations, and scene lighting. The previewer then generates one of two descriptions of the object--a series of perspective views or a polygonal model--which is then used by a fringe rendering engine to compute fringes specific to hologram type. The images are viewed on the second generation MIT Holographic Video System. This allows a viewer to compare holographic stereograms with fully-computed holograms originating from the same database and comes closer to the goal of a single pipeline being able to display the same data in different formats.

Preview-Based Stable-Inversion for Output Tracking

NASA Technical Reports Server (NTRS)

Zou, Qing-Ze; Devasia, Santosh

1999-01-01

Stable Inversion techniques can be used to achieve high-accuracy output tracking. However, for nonminimum phase systems, the inverse is non-causal - hence the inverse has to be pre-computed using a pre-specified desired-output trajectory. This requirement for pre-specification of the desired output restricts the use of inversion-based approaches to trajectory planning problems (for nonminimum phase systems). In the present article, it is shown that preview information of the desired output can be used to achieve online inversion-based output tracking of linear systems. The amount of preview-time needed is quantified in terms of the tracking error and the internal dynamics of the system (zeros of the system). The methodology is applied to the online output tracking of a flexible structure and experimental results are presented.

de Vries, Hein; Candel, Math; van de Kar, Angelique; van Osch, Liesbeth

2013-01-01

Background Adherence to Internet-delivered lifestyle interventions using multiple tailoring is suboptimal. Therefore, it is essential to invest in proactive strategies, such as periodic email prompts, to boost re-use of the intervention. Objective This study investigated the influence of content and timing of a single email prompt on re-use of an Internet-delivered computer-tailored (CT) lifestyle program. Methods A sample of municipality employees was invited to participate in the program. All participants who decided to use the program received an email prompting them to revisit the program. A 2×3 (content × timing) design was used to test manipulations of prompt content and timing. Depending on the study group participants were randomly assigned to, they received either a prompt containing standard content (an invitation to revisit the program), or standard content plus a preview of new content placed on the program website. Participants received this prompt after 2, 4, or 6 weeks. In addition to these 6 experimental conditions, a control condition was included consisting of participants who did not receive an additional email prompt. Clicks on the uniform resource locator (URL) provided in the prompt and log-ins to the CT program were objectively monitored. Logistic regression analyses were conducted to determine whether prompt content and/or prompt timing predicted clicking on the URL and logging in to the CT program. Results Of all program users (N=240), 206 participants received a subsequent email prompting them to revisit the program. A total of 53 participants (25.7%) who received a prompt reacted to this prompt by clicking on the URL, and 25 participants (12.1%) actually logged in to the program. There was a main effect of prompt timing; participants receiving an email prompt 2 weeks after their first visit clicked on the URL significantly more often compared with participants that received the prompt after 4 weeks (odds ratio [OR] 3.069, 95% CI 1.392-6.765, P=.005) and after 6 weeks (OR 4.471, 95% CI 1.909-10.471, P=.001). Furthermore, participants who received an email prompt 2 weeks after their first visit logged in to the program significantly more often compared to participants receiving the prompt after 6 weeks (OR 16.356, 95% CI 2.071-129.196, P=.008). A trend was observed with regard to prompt content. Participants receiving a prompt with additional content were more likely to log in to the program compared to participants who received a standard prompt. However, this result was not statistically significant (OR 2.286, 95% CI 0.892-5.856, P=.09). Conclusions The key findings suggest that boosting revisits to a CT program benefits most from relatively short prompt timing. Furthermore, a preview of new website content may be added to a standard prompt to further increase its effectiveness in persuading people to log in to the program. PMID:23363466

Sandholtz, Judith Haymore; Ringstaff, Cathy

2011-10-01

This study investigated the extent to which teacher professional development led to changes in science instruction in K-2 classrooms in rural school districts. The research specifically examined changes in (a) teachers' content knowledge in science; (b) teachers' self-efficacy related to teaching science; (c) classroom instructional time allotted to science; and (d) instructional strategies used in science. The study also investigated contextual factors contributing to or hindering changes in science instruction. Data sources included a teacher survey, a self-efficacy assessment, content knowledge tests, interviews, and classroom observations. After one year in the program, teachers showed increased content knowledge and self-efficacy in teaching science; they spent more instructional time on science and began using different instructional strategies. Key contextual factors included curricular demands, resources, administrative support, and support from other teachers.

Operator priming and generalization of practice in adults' simple arithmetic.

PubMed

Chen, Yalin; Campbell, Jamie I D

2016-04-01

There is a renewed debate about whether educated adults solve simple addition problems (e.g., 2 + 3) by direct fact retrieval or by fast, automatic counting-based procedures. Recent research testing adults' simple addition and multiplication showed that a 150-ms preview of the operator (+ or ×) facilitated addition, but not multiplication, suggesting that a general addition procedure was primed by the + sign. In Experiment 1 (n = 36), we applied this operator-priming paradigm to rule-based problems (0 + N = N, 1 × N = N, 0 × N = 0) and 1 + N problems with N ranging from 0 to 9. For the rule-based problems, we found both operator-preview facilitation and generalization of practice (e.g., practicing 0 + 3 sped up unpracticed 0 + 8), the latter being a signature of procedure use; however, we also found operator-preview facilitation for 1 + N in the absence of generalization, which implies the 1 + N problems were solved by fact retrieval but nonetheless were facilitated by an operator preview. Thus, the operator preview effect does not discriminate procedure use from fact retrieval. Experiment 2 (n = 36) investigated whether a population with advanced mathematical training-engineering and computer science students-would show generalization of practice for nonrule-based simple addition problems (e.g., 1 + 4, 4 + 7). The 0 + N problems again presented generalization, whereas no nonzero problem type did; but all nonzero problems sped up when the identical problems were retested, as predicted by item-specific fact retrieval. The results pose a strong challenge to the generality of the proposal that skilled adults' simple addition is based on fast procedural algorithms, and instead support a fact-retrieval model of fast addition performance.

2017-09-01

Background Children with leg length discrepancy often undergo repeat imaging. Therefore, every effort to reduce radiation dose is important. Using low dose preview images and noise reduction software rather than diagnostic images for length measurements might contribute to reducing dose. Purpose To compare leg length measurements performed on diagnostic images and low dose preview images both acquired using a low-dose bi-planar imaging system. Material and Methods Preview and diagnostic images from 22 patients were retrospectively collected (14 girls, 8 boys; mean age, 12.8 years; age range, 10-15 years). All images were anonymized and measured independently by two musculoskeletal radiologists. Three sets of measurements were performed on all images; the mechanical axis lines of the femur and the tibia as well as the anatomical line of the entire extremity. Statistical significance was tested with a paired t-test. Results No statistically significant difference was found between measurements performed on the preview and on the diagnostic image. The mean tibial length difference between the observers was -0.06 cm (95% confidence interval [CI], -0.12 to 0.01) and -0.08 cm (95% CI, -0.21 to 0.05), respectively; 0.10 cm (95% CI, 0.02-0.17) and 0.06 cm (95% CI, -0.02 to 0.14) for the femoral measurements and 0.12 cm (95% CI, -0.05 to 0.26) and 0.08 cm (95% CI, -0.02 to 0.19) for total leg length discrepancy. ICCs were >0.99 indicating excellent inter- and intra-rater reliability. Conclusion The data strongly imply that leg length measurements performed on preview images from a low-dose bi-planar imaging system are comparable to measurements performed on diagnostic images.

No differences in grades or level of satisfaction in a flipped classroom for neuroanatomy

Objective The intensive nature of a 5- or 6-week teaching block poses unique problems for adequate delivery of content. This study was designed to compare the delivery of a unit of undergraduate neuroanatomy in a short summer school period, as a traditionally taught unit, with a rendition given in the form of the “Flipped Classroom.” The aim was to evaluate the effectiveness of the flipped classroom in the intensive mode classroom. Methods The flipped classroom encompassed the same learning outcomes, but students were responsible for covering the content at home in preparation for tutorials that applied their acquired knowledge to higher levels of thinking. The main outcome measures were the final course grades and the level of satisfaction with the course. Results There were no significant differences between the 2 cohorts in final grades (p = .259), self-rated knowledge (p = .182), or overall satisfaction with the course (p = .892). Conclusion This particular design of the flipped classroom did not add value to the intensive mode experience. It may be that this mode of delivery is ill suited to intensive classes for subjects that carry a lot of content. The use of the flipped classroom requires further research to fully evaluate its value. PMID:25902472

Attention and eye-movement control in reading: The selective reading paradigm.

PubMed

Reingold, Eyal M; Sheridan, Heather; Meadmore, Katie L; Drieghe, Denis; Liversedge, Simon P

2016-12-01

We introduced a novel paradigm for investigating covert attention and eye-movement control in reading. In 2 experiments, participants read sentence words (shown in blue color) while ignoring interleaved distractor strings (shown in orange color). Each single-line text display contained a target word and a critical distractor. Critical distractors were located just prior to the target in the text and were either words or symbol strings (e.g., @#%&). Target word availability for parafoveal processing (i.e., preview validity) was also manipulated. The results indicated much shallower processing of distractors than targets, and this pattern was more pronounced for symbol than word distractors. The influences of word frequency and fixation location on first-pass fixation durations on distractors were dramatically different than the well-documented pattern obtained in normal reading. Robust preview benefits were demonstrated both when the critical distractors were fixated and when the critical distractors were skipped. Finally, with the exception of larger preview benefits that were obtained in the condition in which the target and critical distractor were identical, the magnitude of the preview effect was largely unaffected by the nature of the critical distractor. Implications of the present paradigm and findings to the study of eye-movement control in reading are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Optimal control to modelling motorcycle rider steering: local versus global coordinate systems in rider preview

NASA Astrophysics Data System (ADS)

Rowell, S.; Popov, A. A.; Meijaard, J. P.

2010-04-01

The response of a motorcycle is heavily dependent on the rider's control actions, and consequently a means of replicating the rider's behaviour provides an important extension to motorcycle dynamics. The primary objective here is to develop effective path-following simulations and to understand how riders control motorcycles. Optimal control theory is applied to the tracking of roadway by a motorcycle, using a non-linear motorcycle model operating in free control by steering torque input. A path-following controller with road preview is designed by minimising tracking errors and control effort. Tight controls with high weightings on performance and loose controls with high weightings on control power are defined. Special attention is paid to the modelling of multipoint preview in local and global coordinate systems. The controller model is simulated over a standard single lane-change manoeuvre. It is argued that the local coordinates point of view is more representative of the way that a human rider operates and interprets information. The simulations suggest that for accurate path following, using optimal control, the problem must be solved by the local coordinates approach in order to achieve accurate results with short preview horizons. Furthermore, some weaknesses of the optimal control approach are highlighted here.

Adult age differences in the perceptual span during reading.

PubMed

Risse, Sarah; Kliegl, Reinhold

2011-06-01

Following up on research suggesting an age-related reduction in the rightward extent of the perceptual span during reading (Rayner, Castelhano, & Yang, 2009), we compared old and young adults in an N + 2-boundary paradigm in which a nonword preview of word N + 2 or word N + 2 itself is replaced by the target word once the eyes cross an invisible boundary located after word N. The intermediate word N + 1 was always three letters long. Gaze durations on word N + 2 were significantly shorter for identical than nonword N + 2 preview both for young and for old adults, with no significant difference in this preview benefit. Young adults, however, did modulate their gaze duration on word N more strongly than old adults in response to the difficulty of the parafoveal word N + 1. Taken together, the results suggest a dissociation of preview benefit and parafoveal-on-foveal effect. Results are discussed in terms of age-related decline in resilience towards distributed processing while simultaneously preserving the ability to integrate parafoveal information into foveal processing. As such, the present results relate to proposals of regulatory compensation strategies older adults use to secure an overall reading speed very similar to that of young adults.

Student perception of writing in the science classroom

NASA Astrophysics Data System (ADS)

Deakin, Kathleen J.

This study examines factors that shape four student's perceptions of writing tasks in their science classroom. This qualitative retrospective interview study focuses on four students concurrently enrolled in honors English and honors biology. This research employs a phenomenological perspective on writing, examining whether the writing strategies students acquire in the Language Arts classroom manifest in the content areas. I also adopt Bandura's theoretical perspective on self-efficacy as well as Hillock's notion of writing as inquiry and meaning making. This study concludes that students need ample opportunity to generate content and language that will help reveal a purpose and genre for writing tasks in the content areas. Although all four students approached the writing tasks differently in this study, the tasks set before them were opportunities for replication rather than inquiry Through the case studies of four students as well as current research on content writing, this project works to inform all content area teachers about student perceptions of writing in the content areas.

The effect of high- and low-frequency previews and sentential fit on word skipping during reading

PubMed Central

Angele, Bernhard; Laishley, Abby; Rayner, Keith; Liversedge, Simon P.

2014-01-01

In a previous gaze-contingent boundary experiment, Angele and Rayner (2012) found that readers are likely to skip a word that appears to be the definite article the even when syntactic constraints do not allow for articles to occur in that position. In the present study, we investigated whether the word frequency of the preview of a three-letter target word influences a reader’s decision to fixate or skip that word. We found that the word frequency rather than the felicitousness (syntactic fit) of the preview affected how often the upcoming word was skipped. These results indicate that visual information about the upcoming word trumps information from the sentence context when it comes to making a skipping decision. Skipping parafoveal instances of the therefore may simply be an extreme case of skipping high-frequency words. PMID:24707791

Search guidance is proportional to the categorical specificity of a target cue.

PubMed

Schmidt, Joseph; Zelinsky, Gregory J

2009-10-01

Visual search studies typically assume the availability of precise target information to guide search, often a picture of the exact target. However, search targets in the real world are often defined categorically and with varying degrees of visual specificity. In five target preview conditions we manipulated the availability of target visual information in a search task for common real-world objects. Previews were: a picture of the target, an abstract textual description of the target, a precise textual description, an abstract + colour textual description, or a precise + colour textual description. Guidance generally increased as information was added to the target preview. We conclude that the information used for search guidance need not be limited to a picture of the target. Although generally less precise, to the extent that visual information can be extracted from a target label and loaded into working memory, this information too can be used to guide search.

Out of the corner of my eye: Foveal semantic load modulates parafoveal processing in reading

PubMed Central

Payne, Brennan R.; Stites, Mallory C.; Federmeier, Kara D.

2016-01-01

In two experiments, we examined the impact of foveal semantic expectancy and congruity on parafoveal word processing during reading. Experiment 1 utilized an eye-tracking gaze contingent display change paradigm, and Experiment 2 measured event-related brain potentials (ERP) in a modified flanker RSVP paradigm. Eye-tracking and ERP data converged to reveal graded effects of foveal load on parafoveal processing. In Experiment 1, when word n was highly expected, and thus foveal load was low, there was a large parafoveal preview benefit to word n + 1. When word n was unexpected but still plausible, preview benefits to n + 1 were reduced in magnitude, and when word n was semantically incongruent, the preview benefit to n + 1 was unreliable in early-pass measures. In Experiment 2, ERPs indicated that when word n was expected, and thus foveal load on was low, readers successfully discriminated between valid and orthographically invalid previews during parafoveal perception. However, when word n was unexpected, parafoveal processing of n + 1 was reduced, and it was eliminated when word n was semantically incongruent. Taken together, these findings suggest that sentential context modulates the allocation of attention in the parafovea, such that covert allocation of attention to parafoveal processing is disrupted when foveal words are inconsistent with expectations based on various contextual constraints.

The psychological characteristics of experiences that influence science motivation and content knowledge

Bathgate, Meghan; Schunn, Christian

2017-11-01

While motivational changes towards science are common during adolescence, our work asks which perceived classroom experiences are most strongly related to these changes. Additionally, we examine which experiences are most strongly associated with learning classroom content. In particular, using self-reports from a sample of approximately 3000 middle school students, this study investigates the influence of perceived science classroom experiences, namely student engagement and perceived success, on motivational change (fascination, values, competency belief) and content knowledge. Controlling for demographic information, school effects, and initial levels of motivation and content knowledge, we find that dimensions of engagement (affect, behavioural/cognitive) and perceived success are differentially associated with changes in particular motivational constructs and learning. Affective engagement is positively associated with motivational outcomes and negatively associated with learning outcomes, behavioural-cognitive engagement is associated only with learning, and perceived success is related only to motivational outcomes. Theoretical and practical implications are discussed.

An interactive online approach to small-group student presentations and discussions.

2017-12-01

Student presentations had been widely implemented across content areas, including health sciences education. However, due to various limitations, small-group student presentations in the classroom may not reach their full potential for student learning. To address challenges with presentations in the classroom, we redesigned the assignment by having students present and discuss online using VoiceThread, a cloud-based presentation and discussion tool. First-year students pursuing a Doctor of Dental Surgery degree were assigned into small groups to present physiology content and to discuss that content online. This assignment was similar to traditional student classroom presentations, with the exception that the entire assignment was conducted online. The primary purpose of this exploratory study was to investigate the impact of the online format on the discussion quality. Another purpose of the study was to examine students' perceptions of using VoiceThread for presenting and learning, as well as the online interactions between the presenter and audience. Students posted a higher number of questions and comments than required by the assignment. The questions from students were also higher level questions, and the answers to these questions were more thorough compared with what we had previously observed in classroom presentations. The survey results showed that students preferred using VoiceThread for presenting, learning from other presentations, and discussing presentation content over performing this process in the classroom. Preliminary findings suggested that having dental students make presentations and hold discussions online might help address the challenges of student presentations in the classroom.

The effects of teacher read-alouds and student silent reading on predominantly bilingual high school seniors’ learning and retention of social studies content

Reed, Deborah K.; Swanson, Elizabeth; Petscher, Yaacov; Vaughn, Sharon

2015-01-01

Teacher read-alouds (TRA) are common in middle and high school content area classes. Because the practice of reading the textbook out loud to students is often used out of concern about students’ ability to understand and learn from text when reading silently (SR), this randomized controlled trial was designed to experimentally manipulate text reading while blocking on all other instructional elements to determine the relative effects on learning content. Predominantly Spanish–English bilingual twelfth-graders (n = 123) were randomly assigned to either a TRA or SR condition and provided 1 week of high quality instruction in US history. Daily lessons included teaching key terms in the passage, previewing text headings, and conducting comprehension checks. Results of immediate, 1-week delayed, and 1-month delayed assessments of content learning revealed no significant differences between the two groups. Students were also asked to rate the method of reading they believed best helped them understand and remember information. Students in the SR condition more consistently agreed that reading silently was beneficial. Findings suggest low performing adolescents of different linguistic backgrounds can learn content as well when reading appropriately challenging text silently as when the teacher reads the text aloud to them.

Character order processing in Chinese reading.

PubMed

Gu, Junjuan; Li, Xingshan; Liversedge, Simon P

2015-02-01

We explored how character order information is encoded in isolated word processing or Chinese sentence reading in 2 experiments using a masked priming paradigm and a gaze-contingent display-change paradigm. The results showed that response latencies in the lexical decision task and reading times on the target word region were longer in the unrelated condition (the prime or the preview was unrelated with the target word) than the transposed-character condition (the prime or the preview was a transposition of the 2 characters of the target word), which were respectively longer than in the identity condition (the prime or preview was identical to the target word). These results show that character order is encoded at an early stage of processing in Chinese reading, but character position encoding was not strict. We also found that character order encoding was similar for single-morpheme and multiple-morpheme words, suggesting that morphemic status does not affect character order encoding. The current results represent an early contribution to our understanding of character order encoding during Chinese reading.

Robust preview control for a class of uncertain discrete-time systems with time-varying delay.

PubMed

Li, Li; Liao, Fucheng

2018-02-01

This paper proposes a concept of robust preview tracking control for uncertain discrete-time systems with time-varying delay. Firstly, a model transformation is employed for an uncertain discrete system with time-varying delay. Then, the auxiliary variables related to the system state and input are introduced to derive an augmented error system that includes future information on the reference signal. This leads to the tracking problem being transformed into a regulator problem. Finally, for the augmented error system, a sufficient condition of asymptotic stability is derived and the preview controller design method is proposed based on the scaled small gain theorem and linear matrix inequality (LMI) technique. The method proposed in this paper not only solves the difficulty problem of applying the difference operator to the time-varying matrices but also simplifies the structure of the augmented error system. The numerical simulation example also illustrates the effectiveness of the results presented in the paper. Copyright © 2018 ISA. Published by Elsevier Ltd. All rights reserved.

Exploring the repetition bias in voluntary task switching.

PubMed

Mittelstädt, Victor; Dignath, David; Schmidt-Ott, Magdalena; Kiesel, Andrea

2018-01-01

In the voluntary task-switching paradigm, participants are required to randomly select tasks. We reasoned that the consistent finding of a repetition bias (i.e., participants repeat tasks more often than expected by chance) reflects reasonable adaptive task selection behavior to balance the goal of random task selection with the goals to minimize the time and effort for task performance. We conducted two experiments in which participants were provided with variable amount of preview for the non-chosen task stimuli (i.e., potential switch stimuli). We assumed that switch stimuli would initiate some pre-processing resulting in improved performance in switch trials. Results showed that reduced switch costs due to extra-preview in advance of each trial were accompanied by more task switches. This finding is in line with the characteristics of rational adaptive behavior. However, participants were not biased to switch tasks more often than chance despite large switch benefits. We suggest that participants might avoid effortful additional control processes that modulate the effects of preview on task performance and task choice.

Tackling action-based video abstraction of animated movies for video browsing

NASA Astrophysics Data System (ADS)

Ionescu, Bogdan; Ott, Laurent; Lambert, Patrick; Coquin, Didier; Pacureanu, Alexandra; Buzuloiu, Vasile

2010-07-01

We address the issue of producing automatic video abstracts in the context of the video indexing of animated movies. For a quick browse of a movie's visual content, we propose a storyboard-like summary, which follows the movie's events by retaining one key frame for each specific scene. To capture the shot's visual activity, we use histograms of cumulative interframe distances, and the key frames are selected according to the distribution of the histogram's modes. For a preview of the movie's exciting action parts, we propose a trailer-like video highlight, whose aim is to show only the most interesting parts of the movie. Our method is based on a relatively standard approach, i.e., highlighting action through the analysis of the movie's rhythm and visual activity information. To suit every type of movie content, including predominantly static movies or movies without exciting parts, the concept of action depends on the movie's average rhythm. The efficiency of our approach is confirmed through several end-user studies.

Potential Values of Incorporating a Multiple-Choice Question Construction in Physics Experimentation Instruction

NASA Astrophysics Data System (ADS)

Yu, Fu-Yun; Liu, Yu-Hsin

2005-09-01

The potential value of a multiple-choice question-construction instructional strategy for the support of students’ learning of physics experiments was examined in the study. Forty-two university freshmen participated in the study for a whole semester. A constant comparison method adopted to categorize students’ qualitative data indicated that the influences of multiple-choice question construction were evident in several significant ways (promoting constructive and productive studying habits; reflecting and previewing course-related materials; increasing in-group communication and interaction; breaking passive learning style and habits, etc.), which, worked together, not only enhanced students’ comprehension and retention of the obtained knowledge, but also helped distil a sense of empowerment and learning community within the participants. Analysis with one-group t-tests, using 3 as the expected mean, on quantitative data further found that students’ satisfaction toward past learning experience, and perceptions toward this strategy’s potentials for promoting learning were statistically significant at the 0.0005 level, while learning anxiety was not statistically significant. Suggestions for incorporating question-generation activities within classroom and topics for future studies were rendered.

Lexical and sublexical semantic preview benefits in Chinese reading.

PubMed

Yan, Ming; Zhou, Wei; Shu, Hua; Kliegl, Reinhold

2012-07-01

Semantic processing from parafoveal words is an elusive phenomenon in alphabetic languages, but it has been demonstrated only for a restricted set of noncompound Chinese characters. Using the gaze-contingent boundary paradigm, this experiment examined whether parafoveal lexical and sublexical semantic information was extracted from compound preview characters. Results generalized parafoveal semantic processing to this representative set of Chinese characters and extended the parafoveal processing to radical (sublexical) level semantic information extraction. Implications for notions of parafoveal information extraction during Chinese reading are discussed. 2012 APA, all rights reserved

Readers differ considerably in their speed of self-paced reading. One factor known to influence fixation durations in reading is the preprocessing of words in parafoveal vision. Here we investigated whether individual differences in reading speed or the amount of information extracted from upcoming words (the preview benefit) can be explained by basic differences in extrafoveal vision—i.e., the ability to recognize peripheral letters with or without the presence of flanking letters. Forty participants were given an adaptive test to determine their eccentricity thresholds for the identification of letters presented either in isolation (extrafoveal acuity) or flanked by other letters (crowded letter recognition). In a separate eye-tracking experiment, the same participants read lists of words from left to right, while the preview of the upcoming words was manipulated with the gaze-contingent moving window technique. Relationships between dependent measures were analyzed on the observational level and with linear mixed models. We obtained highly reliable estimates both for extrafoveal letter identification (acuity and crowding) and measures of reading speed (overall reading speed, size of preview benefit). Reading speed was higher in participants with larger uncrowded windows. However, the strength of this relationship was moderate and it was only observed if other sources of variance in reading speed (e.g., the occurrence of regressive saccades) were eliminated. Moreover, the size of the preview benefit—an important factor in normal reading—was larger in participants with better extrafoveal acuity. Together, these results indicate a significant albeit moderate contribution of extrafoveal vision to individual differences in reading speed. PMID:25789812

Object-based attention: strength of object representation and attentional guidance.

PubMed

Shomstein, Sarah; Behrmann, Marlene

2008-01-01

Two or more features belonging to a single object are identified more quickly and more accurately than are features belonging to different objects--a finding attributed to sensory enhancement of all features belonging to an attended or selected object. However, several recent studies have suggested that this "single-object advantage" may be a product of probabilistic and configural strategic prioritizations rather than of object-based perceptual enhancement per se, challenging the underlying mechanism that is thought to give rise to object-based attention. In the present article, we further explore constraints on the mechanisms of object-based selection by examining the contribution of the strength of object representations to the single-object advantage. We manipulated factors such as exposure duration (i.e., preview time) and salience of configuration (i.e., objects). Varying preview time changes the magnitude of the object-based effect, so that if there is ample time to establish an object representation (i.e., preview time of 1,000 msec), then both probability and configuration (i.e., objects) guide attentional selection. If, however, insufficient time is provided to establish a robust object-based representation, then only probabilities guide attentional selection. Interestingly, at a short preview time of 200 msec, when the two objects were sufficiently different from each other (i.e., different colors), both configuration and probability guided attention selection. These results suggest that object-based effects can be explained both in terms of strength of object representations (established at longer exposure durations and by pictorial cues) and probabilistic contingencies in the visual environment.

Campbell, Todd; Abd-Hamid, Nor Hashidah

2013-08-01

This study describes the development of an instrument to investigate the extent to which technology is integrated in science instruction in ways aligned to science reform outlined in standards documents. The instrument was developed by: (a) creating items consistent with the five dimensions identified in science education literature, (b) establishing content validity with both national and international content experts, (c) refining the item pool based on content expert feedback, (d) piloting testing of the instrument, (e) checking statistical reliability and item analysis, and (f) subsequently refining and finalization of the instrument. The TUSI was administered in a field test across eleven classrooms by three observers, with a total of 33 TUSI ratings completed. The finalized instrument was found to have acceptable inter-rater intraclass correlation reliability estimates. After the final stage of development, the TUSI instrument consisted of 26-items separated into the original five categories, which aligned with the exploratory factor analysis clustering of the items. Additionally, concurrent validity of the TUSI was established with the Reformed Teaching Observation Protocol. Finally, a subsequent set of 17 different classrooms were observed during the spring of 2011, and for the 9 classrooms where technology integration was observed, an overall Cronbach alpha reliability coefficient of 0.913 was found. Based on the analyses completed, the TUSI appears to be a useful instrument for measuring how technology is integrated into science classrooms and is seen as one mechanism for measuring the intersection of technological, pedagogical, and content knowledge in science classrooms.

Orthographic and phonological preview benefits: parafoveal processing in skilled and less-skilled deaf readers.

PubMed

Bélanger, Nathalie N; Mayberry, Rachel I; Rayner, Keith

2013-01-01

Many deaf individuals do not develop the high-level reading skills that will allow them to fully take part into society. To attempt to explain this widespread difficulty in the deaf population, much research has honed in on the use of phonological codes during reading. The hypothesis that the use of phonological codes is associated with good reading skills in deaf readers, though not well supported, still lingers in the literature. We investigated skilled and less-skilled adult deaf readers' processing of orthographic and phonological codes in parafoveal vision during reading by monitoring their eye movements and using the boundary paradigm. Orthographic preview benefits were found in early measures of reading for skilled hearing, skilled deaf, and less-skilled deaf readers, but only skilled hearing readers processed phonological codes in parafoveal vision. Crucially, skilled and less-skilled deaf readers showed a very similar pattern of preview benefits during reading. These results support the notion that reading difficulties in deaf adults are not linked to their failure to activate phonological codes during reading.

Streamlining Building Efficiency Evaluation with DOE's Asset Score Preview

2016-08-26

Building Energy Asset Score (Asset Score), developed by the Pacific Northwest National Laboratory (PNNL) for the U.S. Department of Energy (DOE), is a tool to help building owners and managers assess the efficiency of a building's energy-related systems and encourage investment in cost-effective improvements. The Asset Score uses an EnergyPlus model to provide a quick assessment of building energy performance with minimum user inputs of building characteristics and identifies upgrade opportunities. Even with a reduced set of user inputs, data collection remains a challenge for wide-spread adoption, especially when evaluating a large number of buildings. To address this, Asset Scoremore » Preview was developed to allow users to enter as few as seven building characteristics to quickly assess their buildings before a more in-depth analysis. A streamlined assessment from Preview to full Asset Score provides an easy entry point and also enables users who manage a large number of buildings to screen and prioritize buildings that can benefit most from a more detailed evaluation and possible energy efficiency upgrades without intensive data collection.« less

Overconfidence, preview, and probability in strategic planning

The performance of eight subjects in a 'rescue' video game requiring choices as to which node they should fly to in order to rescue the simulated casualties is presently studied with a view to biases and display support criteria in strategic planning. After each choice, the subjects needed to fly a challenging tracking dynamic along a path to reach the next node. The results obtained indicate that the choices of the subjects were less optimal when full preview was offered, perhaps due to subjects' reliance on the simple strategy of choosing routes with the greatest number of casualties.

What Is Construed as Relevant Knowledge in Physics Teaching? Similarities and Differences in How Knowledge and Power Are Staged in Three Lower Secondary Classrooms

Lidar, Malena; Danielsson, Anna T.; Berge, Maria

2018-05-01

The content that is privileged in teaching has consequences for what the students are given the opportunity to learn and can thus be regarded as an aspect of power. We analyse power aspects in the teaching of physics by identifying actions that guide or direct other people's actions, and then analyse similarities and differences in different classrooms in terms of how governance is staged and what potential consequences this can have. The analyses are made on data from classroom activities, documented through video recordings and field notes, in three lower secondary schools in Y8 and Y9, respectively. At first glance, teachers from all three schools adhere to a traditional interpretation of a physics curriculum. But a more in-depth analysis shows that the students in the different classrooms are given quite dissimilar opportunities to participate in teaching and create relationships with the content. What appears to be a desirable way of acting offers different conditions for meaning-making. In an increasingly individualised society where people are expected to be active, reflective and make choices for their own personal good, the students in these three classrooms are offered very different conditions to practice and learn to take part in knowledge-making, connect physics content to their everyday life and exercise informed citizenship.

Embedding Sustainability Instruction across Content Areas: best Classroom Practices from Informal Environmental Education

NASA Astrophysics Data System (ADS)

Clary, R. M.; Walker, R. M.; Wissehr, C.

2017-12-01

Environmental education (EE) facilitates students' scientific and environmental literacy, and addresses content areas including sustainability, ecology, and civic responsibility. However, U.S. science content compartmentalization and EE's interdisciplinary nature historically made it a fragmented curriculum within U.S. schools. To gain a better understanding of effective EE instruction that can be transferred to traditional K-12 classrooms, we researched the interactions between a recognized environmental residential camp and students and teachers from six participating schools using grounded theory methodology. Our research identified the residential learning center's objectives, methods of instruction, and objectives' alignment to the delivered curricula. Data generated included lesson plans, survey responses, and interviews. Students (n = 215) identified wilderness and geology activities as the activities they wanted to experience more; they also identified developing curiosity and a sense of discovery as the most meaningful. Whereas most student-identified meaningful experiences aligned with the center's curricular objectives within the optional units, categories emerged that were not explicitly targeted in the unit activities but were embedded throughout the curriculum in sustainable practices, data collection, and reflections. We propose that embedded activities and implicit instruction can be included across content areas within K-12 classrooms. Teacher modeling and implicit instruction will require minimal classroom time, and facilitate students' scientific and environmental literacy in topics such as sustainability and citizen responsibility.

The flipped classroom experience promotes retention and accountability for learning. The authors report their evaluation of a flipped classroom for accelerated second-degree nursing students during their primary medical-surgical nursing course. Standardized HESI® scores were compared between a group of students who experienced the flipped classroom and a previous group who had traditional teaching methods. Short- and long-term retention was measured using standardized exams 3 months and 12 months following the course. Results indicated that short-term retention was greater and long- term retention was significantly great in the students who were taught using flipped classroom methodology.

Teaching and Learning Science Through Song: Exploring the experiences of students and teachers

Governor, Donna; Hall, Jori; Jackson, David

2013-12-01

This qualitative, multi-case study explored the use of science-content music for teaching and learning in six middle school science classrooms. The researcher sought to understand how teachers made use of content-rich songs for teaching science, how they impacted student engagement and learning, and what the experiences of these teachers and students suggested about using songs for middle school classroom science instruction. Data gathered included three teacher interviews, one classroom observation and a student focus-group discussion from each of six cases. The data from each unit of analysis were examined independently and then synthesized in a multi-case analysis, resulting in a number of merged findings, or assertions, about the experience. The results of this study indicated that teachers used content-rich music to enhance student understanding of concepts in science by developing content-based vocabulary, providing students with alternative examples and explanations of concepts, and as a sense-making experience to help build conceptual understanding. The use of science-content songs engaged students by providing both situational and personal interest, and provided a mnemonic device for remembering key concepts in science. The use of songs has relevance from a constructivist approach as they were used to help students build meaning; from a socio-cultural perspective in terms of student engagement; and from a cognitive viewpoint in that in these cases they helped students make connections in learning. The results of this research have implications for science teachers and the science education community in developing new instructional strategies for the middle school science classroom.

Stanford's Global Climate Change: Professional Development for K-12 Teachers is a unique collaboration between the Stanford School of Education and School of Earth Sciences to provide teacher professional development on the science of global climate change, pedagogical strategies, and curriculum materials. Scientists and education specialists developed a curriculum for middle and high school science classrooms. It addresses the fundamental issues of climate science, the impacts of climate change on society and on global resources, mitigation and adaptation strategies. This project documents in detail the full circle of curriculum development, teacher professional development, classroom implementation, analysis of student achievement data, and curriculum revision. Ongoing evaluation has provided understanding of the unique conditions and requirements of climate change education. In a sample of 750 secondary students in 25 Bay Area classrooms, we found statistically significant differences between post- (x=11.56, sd=4.75) and pre- (x=8.64, sd=4.58) test scores on standardized items and short open-ended essay questions. Through systematic classroom observations (300 observations in 25 classrooms), we documented student engagement and interactions, and the nature of teachers' talk in the classroom. We found that on average, 73.4% of the students were engaged, 14.4% were interacting with peers, and about 12.1% were disengaged. We also documented teacher talk (165 observations) and found that on the average, teachers delivered factual content and talked about classroom processes and spent less time on scientific argumentation, reasoning and/ or analysis. We documented significant differences in the quality of implementation among the teachers. Our study suggests that in addition to strengthening content knowledge and pedagogical content knowledge, professional development for teachers needs to include classroom management strategies, explicit modeling of collaborative work, and greater attention to the quality of teachers' questions and interactions with the students to enhance the quality of student talk and understanding. In our final year of the project, we will focus our observations more tightly on the nature of teacher and student talk to explore student understanding of climate change.

How the viewing of familiar landscapes prior to release allows pigeons to home faster: evidence from GPS tracking.

Biro, Dora; Guilford, Tim; Dell'Omo, Giacomo; Lipp, Hans-Peter

2002-12-01

Providing homing pigeons with a 5 min preview of the landscape at familiar sites prior to release reliably improves the birds' subsequent homing speeds. This phenomenon has been taken to suggest that the visual panorama is involved in familiar-site recognition, yet the exact nature of the improvement has never been elucidated. We employed newly developed miniature Global Positioning System (GPS) tracking technology to investigate how access to visual cues prior to release affects pigeons' flight along the length of the homing route. By applying a variety of novel analytical techniques enabled by the high-resolution GPS data (track efficiency, virtual vanishing bearings, orientation threshold), we localised the preview effect to the first 1000 m of the journey. Birds denied preview of a familiar landscape for 5 min before take-off flew an initially more tortuous path, including a high incidence of circling, possibly as part of an information-gathering strategy to determine their position. Beyond the first 1000 m, no differences were found in the performance of birds with or without preview. That the effect of the visual treatment was evident only in the early part of the journey suggests that lack of access to visual cues prior to release does not result in a non-specific effect on behaviour that is maintained throughout the flight. Instead, it seems that at least some decisions regarding the direction of home can be made prior to release and that such decisions are delayed if visual access to the landscape is denied. Overall, the variety of approaches applied here clearly highlight the potential for future applications of GPS tracking technology in navigation studies.

More target features in visual working memory leads to poorer search guidance: Evidence from contralateral delay activity

PubMed Central

Schmidt, Joseph; MacNamara, Annmarie; Proudfit, Greg Hajcak; Zelinsky, Gregory J.

2014-01-01

The visual-search literature has assumed that the top-down target representation used to guide search resides in visual working memory (VWM). We directly tested this assumption using contralateral delay activity (CDA) to estimate the VWM load imposed by the target representation. In Experiment 1, observers previewed four photorealistic objects and were cued to remember the two objects appearing to the left or right of central fixation; Experiment 2 was identical except that observers previewed two photorealistic objects and were cued to remember one. CDA was measured during a delay following preview offset but before onset of a four-object search array. One of the targets was always present, and observers were asked to make an eye movement to it and press a button. We found lower magnitude CDA on trials when the initial search saccade was directed to the target (strong guidance) compared to when it was not (weak guidance). This difference also tended to be larger shortly before search-display onset and was largely unaffected by VWM item-capacity limits or number of previews. Moreover, the difference between mean strong- and weak-guidance CDA was proportional to the increase in search time between mean strong-and weak-guidance trials (as measured by time-to-target and reaction-time difference scores). Contrary to most search models, our data suggest that trials resulting in the maintenance of more target features results in poor search guidance to a target. We interpret these counterintuitive findings as evidence for strong search guidance using a small set of highly discriminative target features that remain after pruning from a larger set of features, with the load imposed on VWM varying with this feature-consolidation process.

Today's classrooms are significantly influenced by current news events, delivered instantly into the classroom via the Internet. Educators are challenged daily to transform these events into student learning opportunities. In the case of space science, current news events may be the only chance for educators and students to explore the marvels of the Universe. Inspired by these circumstances, the education and news teams developed the Star Witness News science content reading series. These online news stories (also available in downloadable PDF format) mirror the content of Hubble press releases and are designed for upper elementary and middle school level readers to enjoy. Educators can use Star Witness News stories to reinforce students' reading skills while exposing students to the latest Hubble discoveries.

Signs of taste for science: a methodology for studying the constitution of interest in the science classroom

NASA Astrophysics Data System (ADS)

Anderhag, P.; Wickman, P.-O.; Hamza, K. M.

2015-06-01

In this paper we present a methodological approach for analyzing the transformation of interest in science through classroom talk and action. To this end, we use the construct of taste for science as a social and communicative operationalization, or proxy, to the more psychologically oriented construct of interest. To gain a taste for science as part of school science activities means developing habits of performing and valuing certain distinctions about ways to talk, act and be that are jointly construed as belonging in the school science classroom. In this view, to learn science is not only about learning the curriculum content, but also about learning a normative and aesthetic content in terms of habits of distinguishing and valuing. The approach thus complements previous studies on students' interest in science, by making it possible to analyze how taste for science is constituted, moment-by-moment, through talk and action in the science classroom. In developing the method, we supplement theoretical constructs coming from pragmatism and Pierre Bourdieu with empirical data from a lower secondary science classroom. The application of the method to this classroom demonstrates the potential that the approach has for analyzing how conceptual, normative, and aesthetic distinctions within the science classroom interact in the constitution of taste for, and thereby potentially also in the development of interest in science among students.

Developing pre-service science teachers' pedagogical content knowledge by using training program

Udomkan, Watinee; Suwannoi, Paisan

2018-01-01

A training program was developed for enhancing pre-service science teachers' pedagogical content knowledge (PCK). The pre-service science teachers are able to: understand science curriculum, knowledge of assessment in science, knowledge of students' understanding of science, instructional strategies and orientations towards science teaching, which is conceptualized as PCK [5]. This study examined the preservice science teachers' understandings and their practices which include five pre-service science teachers' PCK. In this study, the participants demonstrated their PCK through the process of the training program by writing content representations (CoRes), preparing the lesson plans, micro-teaching, and actual teaching respectively. All pre-service science teachers' performs were collected by classroom observations. Then, they were interviewed. The results showed that the pre-service science teachers progressively developed knowledge components of PCK. Micro-teaching is the key activities for developing PCK. However, they had some difficulties in their classroom teaching. They required of sufficient ability to design appropriate instructional strategies and assessment activities for teaching. Blending content and pedagogy is also a matter of great concern. The implication of this study was that science educators can enhance pre-service science teachers' PCK by fostering their better understandings of the instructional strategies, assessment activities and blending between content and pedagogy in their classroom.

NASA Technical Reports Server (NTRS)

Green, J.; Davenport, E. L.; Engler, H. F.; Sears, W. E., III

1982-01-01

Human control strategy is measured through use of a psychologically-based computer simulation which reflects a broader theory of control behavior. The simulation is called the human operator performance emulator, or HOPE. HOPE was designed to emulate control learning in a one-dimensional preview tracking task and to measure control strategy in that setting. When given a numerical representation of a track and information about current position in relation to that track, HOPE generates positions for a stick controlling the cursor to be moved along the track. In other words, HOPE generates control stick behavior corresponding to that which might be used by a person learning preview tracking.

Effects of colour on preview search: anticipatory and inhibitory biases for colour.

Two experiments are reported examining the effects of colour grouping, colour change and target colour foreknowledge under preview search conditions (Watson and Humphreys, 1997). In Experiment 1 we manipulated the colour homogeneity of the old items at initial presentation, and the colour these items subsequently changed into. In all cases participants knew the colour of the target. We found that when the old items changed into the same colour as the new search set, search performance was affected. In Experiment 2 participants did not know the colour of the target. Here we found evidence for a negative colour-based carry-over effect that slowed search for new targets carrying the colour of the old items. This occurred even when the old items changed their original colour and the new target was a singleton. Collectively the results suggest an important role for both colour grouping and colour-based inhibition in the successful rejection of old distractors. The consequence of this, however, is that new stimuli that may carry the critical attribute may take longer to detect. We discuss the results in relation to prior 'feature-blind' accounts of preview effects on visual search.

A Theoretical Analysis of the Perceptual Span based on SWIFT Simulations of the n + 2 Boundary Paradigm

PubMed Central

Risse, Sarah; Hohenstein, Sven; Kliegl, Reinhold; Engbert, Ralf

2014-01-01

Eye-movement experiments suggest that the perceptual span during reading is larger than the fixated word, asymmetric around the fixation position, and shrinks in size contingent on the foveal processing load. We used the SWIFT model of eye-movement control during reading to test these hypotheses and their implications under the assumption of graded parallel processing of all words inside the perceptual span. Specifically, we simulated reading in the boundary paradigm and analysed the effects of denying the model to have valid preview of a parafoveal word n + 2 two words to the right of fixation. Optimizing the model parameters for the valid preview condition only, we obtained span parameters with remarkably realistic estimates conforming to the empirical findings on the size of the perceptual span. More importantly, the SWIFT model generated parafoveal processing up to word n + 2 without fitting the model to such preview effects. Our results suggest that asymmetry and dynamic modulation are plausible properties of the perceptual span in a parallel word-processing model such as SWIFT. Moreover, they seem to guide the flexible distribution of processing resources during reading between foveal and parafoveal words. PMID:24771996

Effects of visual span on reading speed and parafoveal processing in eye movements during sentence reading.

PubMed

Risse, Sarah

2014-07-15

The visual span (or ‘‘uncrowded window’’), which limits the sensory information on each fixation, has been shown to determine reading speed in tasks involving rapid serial visual presentation of single words. The present study investigated whether this is also true for fixation durations during sentence reading when all words are presented at the same time and parafoveal preview of words prior to fixation typically reduces later word-recognition times. If so, a larger visual span may allow more efficient parafoveal processing and thus faster reading. In order to test this hypothesis, visual span profiles (VSPs) were collected from 60 participants and related to data from an eye-tracking reading experiment. The results confirmed a positive relationship between the readers’ VSPs and fixation-based reading speed. However, this relationship was not determined by parafoveal processing. There was no evidence that individual differences in VSPs predicted differences in parafoveal preview benefit. Nevertheless, preview benefit correlated with reading speed, suggesting an independent effect on oculomotor control during reading. In summary, the present results indicate a more complex relationship between the visual span, parafoveal processing, and reading speed than initially assumed. © 2014 ARVO.

Gamification has been extensively implemented and studied in corporate settings and has proven to be more effective than traditional employee-training programs, however, few classroom studies of gamification have been reported in the literature. Our study explored the potential of gamified on-line undergraduate physics content as a mechanism to enhance student learning and motivation. Specifically, the main objective of this work was to determine whether extrinsic motivation indicators commonly used in video games could increase student engagement with course content outside of the classroom. Life Science students taking an introductory physics course were provided access to gamified multiple choice quizzes as part of their course assessment. The quizzes incorporated common gaming elements such as points, streaks, leaderboards and achievements, as well as some gamified graphical enhancements and feedback. Student attitudes and performance among those using the gamified quizzes were examined and compared to non-gamified control groups within the same course. Student engagement was quantified through examining student participation above and beyond the minimum course requirements. The results showed that gaming techniques are significantly correlated with increased engagement with course material outside of the classroom. These results may assist instructors in engaging and motivating students outside the classroom through carefully designed online and distance-delivered undergraduate physics content. Furthermore, the gaming elements incorporated in this study were not specifically tied to the physics content and can be easily translated to any educational setting.

Connecting students and teachers in classrooms with science, technology, engineering, and mathematics (STEM) experts provides an invaluable opportunity. Subject matter experts can share exciting science and science-related events as well as help to "translate" science being conducted by professionals. The Expedition Earth and Beyond (EEAB) Program, facilitated by the Astromaterials Research and Exploration Science (ARES) Division at the NASA Johnson Space Center, has been providing virtual access to subject matter experts through classroom connection webinars for the last five years. Each year, the reach of these events has grown considerably, especially over the last nine months. These virtual connections not only help engage students with role models, but are also designed to help teachers address concepts and content standards they are required to teach. These events also enable scientists and subject matter experts to help "translate" current science in an engaging and understandable manner while actively involving classrooms in the journey of science and exploration.

Using superheroes such as Hawkeye, Wonder Woman and the Invisible Woman in the physics classroom

2018-05-01

Communication of difficult concepts in the physics classroom can be negatively affected by the absence of a strong link between physics content and the experiences or interests of students. One possible method towards addressing this issue is to motivate physics content with reference to popular culture figures such as superheroes. We find ourselves in an age where superhero films are immensely popular with numerous superhero films scheduled for release over the coming years. With many students familiar with many of these characters and their superpowers, superheroes can facilitate a unique platform to aid in the dissemination of physics materials in the classroom. In this paper, we present three examples where superheroes can be used to motivate learning objectives in physics and, if desired, promote critical thinking on behalf of the student. We also reflect on how using the superhero genre in the classroom can be used to address underrepresentation of women, stereotyping, and diversity issues in physics.

Context-based curriculum reforms in chemistry education are thought to bring greater diversity to the ways in which chemistry teachers organize their teaching. First and foremost, students are expected to perceive this diversity. However, empirical research on how students perceive their teacher's teaching in context-based chemistry classrooms, and whether this teaching differs from traditional chemistry lessons, is scarce. This study aims to develop our understanding of what teaching looks like, according to students, in context-based chemistry classrooms compared with traditional chemistry classrooms. As such, it might also provide a better understanding of whether teachers implement and attain the intentions of curriculum developers. To study teacher behaviour we used three theoretical perspectives deemed to be important for student learning: a content perspective, a learning activities perspective, and an interpersonal perspective. Data were collected from 480 students in 24 secondary chemistry classes in the Netherlands. Our findings suggest that, according to the students, the changes in teaching in context-based chemistry classrooms imply a lessening of the emphasis on fundamental chemistry and the use of a teacher-centred approach, compared with traditional chemistry classrooms. However, teachers in context-based chemistry classrooms seem not to display more 'context-based' teaching behaviour, such as emphasizing the relation between chemistry, technology, and society and using a student-centred approach. Furthermore, students in context-based chemistry classrooms perceive their teachers as having less interpersonal control and showing less affiliation than teachers in traditional chemistry classrooms. Our findings should be interpreted in the context of former and daily experiences of both teachers and students. As only chemistry is reformed in the schools in which context-based chemistry is implemented, it is challenging for both students and teachers to deal with these reforms.

Popularity of videos for classroom instruction has increased over the years due to affordability and user-friendliness of today's digital video cameras. This prevalence has led to an increase in flipped, K-12 classrooms countrywide. However, quantitative data establishing the appropriate video length to foster authentic learning is limited, particularly in middle-level classrooms. We focus on this aspect of video technology in two flipped science classrooms at the middle school level to determine the optimal video length to enable learning, increase retention and support student motivation. Our results indicate that while assessments directly following short videos were slightly higher, these findings were not significantly different from scores following longer videos. While short-term retention of material did not seem to be influenced by video length, longer-term retention for males and students with learning disabilities was higher following short videos compared to long as assessed on summative assessments. Students self-report that they were more engaged, had enhanced focus, and had a perceived higher retention of content following shorter videos. This study has important implications for student learning, application of content, and the development of critical thinking skills. This is particularly paramount in an era where content knowledge is just a search engine away.

2018-03-01

Recent science education reforms highlight the importance for teachers to implement effective instructional practices that promote student learning of science and engineering content and their practices. Effective classroom discussion has been shown to support the learning of science, but work is needed to examine teachers' enactment of engineering design-based science curricula by focusing on the content, complexity, structure, and orchestration of classroom discussions. In the present study, we explored teacher-student talk with respect to science in a middle school curriculum focused on genetics and genetic engineering. Our study was guided by the following major research question: What are the similarities and differences in teacher talk moves that occurred within an engineering design-based science unit enacted by two teachers? Through qualitative and quantitative approaches, we found that there were clear differences in two teachers' use of questioning strategies and presentation of new knowledge that affected the level of student involvement in classroom discourse and the richness and details of student contributions to the conversations. We also found that the verbal explanations of science content differed between two teachers. Collectively, the findings in this study demonstrate that although the teachers worked together to design an engineering designed-based science curriculum unit, their use of different discussion strategies and patterns, and interactions with students differed to affect classroom discourse.

Teachers in today s classrooms are bound by state required skills, education standards, and high stakes testing. How can they gain skills and confidence to replace units or individual activities with curriculum that incorporates project and inquiry-based learning and promotes authentic research in the classroom? The key to promoting classroom authentic research experiences lies in educator professional development that is structured around teacher needs. The Expedition Earth and Beyond Program is a new geosciences program based at the NASA Johnson Space Center designed to engage, inspire and educate teachers and students in grades 5-14. The program promotes authentic research experiences for classrooms and uses strategies that will help NASA reach its education goals while still allowing educators to teach required standards. Teachers will have access to experts in terrestrial and planetary remote sensing and geoscience; this will enhance their use of content, structure, and relevant experiences to gain the confidence and skills they need to actively engage students in authentic research experiences. Integrated and powerful educational strategies are used to build skills and confidence in teachers. The strategies are as follows: 1) creating Standards-aligned, inquiry-based curricular resources as ready-to-use materials that can be modified by teachers to fit their unique classroom situation; 2) providing ongoing professional development opportunities that focus on active experiences using curricular materials, inquiry-based techniques and expanding content knowledge; 3) connecting science experts to classrooms to deepen content knowledge and provide relevance to classroom activities and real world applications; 4) facilitating students sharing research with their peers and scientists reinforcing their active participation and contributions to research. These components of the Expedition Earth and Beyond Education Program will be enhanced by providing exciting and diverse research opportunities that are inspired by views of Earth from space taken by astronauts on board the International Space Station. The interest and connection to viewing our home planet from space will inevitably spark questions that will drive students to pursue their research investigations, as well as forming a basis for comparisons to the exploration of other planetary bodies in our solar system.

Relating Teacher PCK and Teacher Practice Using Classroom Observation

NASA Astrophysics Data System (ADS)

Barendsen, Erik; Henze, Ineke

2017-09-01

Science teachers' pedagogical content knowledge (PCK) has been researched in many studies, yet little empirical evidence has been found to determine how this knowledge actually informs teachers' actions in the classroom. To complement previous quantitative studies, there is a need for more qualitative studies to investigate the relationship between teacher knowledge (as formulated by the teacher) and classroom practice, especially in the context of an educational innovation. In this study we explored a possible way to investigate this relationship in an in-depth and systematic fashion. To this end, we conducted a case study with a chemistry teacher in the context of the implementation of a context-based science curriculum in The Netherlands. The teacher's PCK was captured using the Content Representation form by Loughran, Mulhall, and Berry. We used an observation table to monitor classroom interactions in such a way that the observations could be related to specific elements of teachers' PCK. Thus, we were able to give a detailed characterization of the correspondences and differences between the teacher's personal PCK and classroom practice. Such an elaborate description turned out to be a useful basis for discussing mechanisms explaining the relationship between teachers' knowledge and teachers' actions.

2008-12-01

ESES 202 is a new general education course in physical science at the University of Illinois's School of Earth, Society and Environment, designed for pre-service K-8 teachers. The goal of the course is to help future classroom teachers become confident with teaching earth science content. The designers of this course include a faculty expert in earth system science, a pre-service teacher and a former middle school science teacher. The goal of the in the curriculum design was to utilize the unique perspectives and experiences of our team. Our poster will highlight the unique nature of the curriculum development outlining the challenges and successes of designing the course. The general format of the class will be a combination of discussions, hands on experiences, and opportunities for students to design their own lessons. Class meetings will be once per week in a three-hour block, allowing students to immediately transfer new content knowledge into classroom activities. The end goal is that they can use these same activities with their students once they are practicing teachers. The content of the course shall be taught using an earth systems approach by showing the relationships among the four spheres: biosphere, hydrosphere, atmospheric, and anthrosphere. There are five units in the course: Introduction to Earth Systems, Carbon Cycle, Water Quality, El Niño and Climate Change. In addition to the science portion of the course, students will spend time reflecting on the classroom activities from the perspective of future educators. Activities will be presented at a late elementary school level; however, time will be devoted to discussing methods to adapt the lesson to different grade levels and differentiation needs within a classroom. Additionally, students in this course will be instructed on how to utilize a multitude of resources from stream tables to science education databases to prepare them for the dynamic nature of the classroom. By the end of the class preservice teachers will have an organized resource binder with science content and classroom activities for each unit. This will serve as an invaluable tool for them when they enter a classroom. Most of the University students who take this course will not yet have had an opportunity to teach in their practicum. By the conclusion of the semester they will have a plethora of experience and resources with increased confidence in teaching earth science.

Assessing the IRIS Professional Development Model: Impact Beyond the Workshops

NASA Astrophysics Data System (ADS)

Hubenthal, M.; Braile, L. W.; Taber, J. J.

2003-12-01

The IRIS Education and Outreach (E&O) Program has developed a highly effective, one-day professional development experience for formal educators. Leveraging the expertise of its consortium, IRIS delivers content including: plate tectonics, propagation of seismic waves, seismographs, Earth's interior structure. At the core of the IRIS professional development model is the philosophy that changes in teacher behavior can be affected by increasing teacher comfort in the classroom. Science and research organizations such as IRIS are able to increase teachers' comfort in the classroom by providing professional development which: increases an educator's knowledge of scientific content, provides educators with a variety of high-quality, scientifically accurate activities to deliver content to students, and provides educators with experiences involving both the content and the educational activities as the primary means of knowledge transfer. As reflected in a 2002-2003 academic year assessment program, this model has proven to be effective at reaching beyond participants and extending into the educators' classrooms. 76% of respondents report increasing the amount of time they spend teaching seismology or related topics in their classroom as a result of participating in IRIS professional development experience. This increase can be directly attributed to the workshop as 90% of participants report using at least one activity modeled during the workshop upon returning to their classrooms. The reported mean activity usage by teachers upon was 4.5 activities per teacher. Since the inception of the professional development model in 1999, IRIS E&O has been committed to evaluation. Data derived from assessment is utilized as a key decision making tool, driving a continuous improvement process. As a result, both the model and the assessment methods have become increasingly refined and sophisticated. The alignment of the professional development model within the IRIS E&O Program framework has resulted in a clarified a definition of success and an increased demand for the collection of new data. Currently, the assessment program is testing tools to examine participant learning, measure the transfer of knowledge and resources from professional development into in classrooms, and measure the use of individual activities.

Social aspects of classroom learning: Results of a discourse analysis in an inquiry-oriented physical chemistry class

NASA Astrophysics Data System (ADS)

Becker, Nicole M.

Engaging students in classroom discourse offers opportunities for students to participate in the construction of joint understandings, to negotiate relationships between different types of evidence, and to practice making evidence-based claims about science content. However, close attention to social aspects of learning is critical to creating inquiry-oriented classroom environments in which students learn with understanding. This study examined the social influences that contribute to classroom learning in an inquiry-oriented undergraduate physical chemistry class using the Process Oriented Guided Inquiry Learning (POGIL) approach. A qualitative approach to analyzing classroom discourse derived from Toulmin's (1968) model of argumentation was used to document patterns in classroom reasoning that reflect normative aspects of social interaction. Adapting the constructs of social and sociomathematical norms from the work of Yackel and Cobb (1996), I describe social aspects of the classroom environment by discussing normative aspects of social interaction (social norms) and discipline-specific criteria related to reasoning and justification in chemistry contexts, referred to here as sociochemical norms. This work discusses four social norms and two sociochemical norms that were documented over a five-week period of observation in Dr. Black's POGIL physical chemistry class. In small group activities, the socially established expectations that students explain reasoning, negotiate understandings of terminology and symbolic representations, and arrive at a consensus on critical thinking questions shaped small group interactions and reasoning. In whole class discussion, there was an expectation that students share reasoning with the class, and that the instructor provide feedback on student reasoning in ways that extended student contributions and elaborated relationships between macroscopic, particulate, and symbolic-level ideas. The ways in which the class constructed evidence-based claims about chemistry content reflected the influence of sociochemical norms that were enacted through classroom discourse. Two sociochemical norms were documented in both whole class and small group activities: first, the class used particulate-level evidence to make claims about chemical and physical properties; second, particular ways of using mathematical reasoning to justify claims about thermodynamics content became normative for the class. These similarities and differences between social and sociochemical norms in small group and whole class discussion highlight ways in which instructor facilitation can support productive interactions in classroom activities.

Modeling the human as a controller in a multitask environment

NASA Technical Reports Server (NTRS)

Govindaraj, T.; Rouse, W. B.

1978-01-01

Modeling the human as a controller of slowly responding systems with preview is considered. Along with control tasks, discrete noncontrol tasks occur at irregular intervals. In multitask situations such as these, it has been observed that humans tend to apply piecewise constant controls. It is believed that the magnitude of controls and the durations for which they remain constant are dependent directly on the system bandwidth, preview distance, complexity of the trajectory to be followed, and nature of the noncontrol tasks. A simple heuristic model of human control behavior in this situation is presented. The results of a simulation study, whose purpose was determination of the sensitivity of the model to its parameters, are discussed.

Energy matters: An investigation of drama pedagogy in the science classroom

NASA Astrophysics Data System (ADS)

Alrutz, Megan

The purpose of this study is to explore and document how informal and improvisational drama techniques affect student learning in the science classroom. While implementing a drama-based science unit, I examined multiple notions of learning, including, but not limited to, traditional notions of achievement, student understanding, student participation in the science classroom, and student engagement with, and knowledge of, science content. Employing an interpretivist research methodology, as outlined by Fredrick Erickson for qualitative analysis in the classroom, I collected data through personal observations; student and teacher interviews; written, artistic and performed class work; video-recorded class work; written tests; and questionnaires. In analyzing the data, I found strong support for student engagement during drama-based science instruction. The drama-based lessons provided structures that drew students into lessons, created enthusiasm for the science curriculum, and encouraged meaningful engagement with, and connections to, the science content, including the application and synthesis of science concepts and skills. By making student contributions essential to each of the lessons, and by challenging students to justify, explain, and clarify their understandings within a dramatic scenario, the classroom facilitators created a conducive learning environment that included both support for student ideas and intellectual rigor. The integration of drama-based pedagogy most affected student access to science learning and content. Students' participation levels, as well as their interest in both science and drama, increased during this drama-based science unit. In addition, the drama-based lessons accommodated multiple learning styles and interests, improving students' access to science content and perceptions of their learning experience and abilities. Finally, while the drama-based science lessons provided multiple opportunities for solidifying understanding of the science content, the data also revealed missed opportunities for sense-making within the delivery of several drama-based science lessons. In conclusion, this study demonstrates how the integration of drama and science prepares students for seeking, accessing, and organizing information in different ways, providing multiple means for students to build knowledge and understanding for actively participating in the changing world around us.

In collaboration with teachers and students at the National Technical Institute for the Deaf (NTID), the Sign Language Skills Classroom Observation (SLSCO) was designed to provide feedback to teachers on their sign language communication skills in the classroom. In the present article, the impetus and rationale for development of the SLSCO is discussed. Previous studies related to classroom signing and observation methodology are reviewed. The procedure for developing the SLSCO is then described. This procedure included (a) interviews with faculty and students at NTID, (b) identification of linguistic features of sign language important for conveying content to deaf students, (c) development of forms for recording observations of classroom signing, (d) analysis of use of the forms, (e) development of a protocol for conducting the SLSCO, and (f) piloting of the SLSCO in classrooms. The results of use of the SLSCO with NTID faculty during a trial year are summarized.

Trussell, Jessica W; Nordhaus, Jason; Brusehaber, Alison; Amari, Brittany

2018-04-17

Deaf and hard-of-hearing (DHH) students have exhibited a morphological knowledge delay that begins in preschool and persists through college. Morphological knowledge is critical to vocabulary understanding and text comprehension in the science classroom. We investigated the effects of morphological instruction, commonly referred to as Word Detectives, on the morphological knowledge of college-age DHH students in a science course. We implemented a multiple probe across behaviors single-case experimental design study with nine student participants. The student participants attended the National Technical Institute for the Deaf. A functional relation was found between the morphological instruction and the student participants' improvement of morphological knowledge regarding the morphemes taught during instruction. These findings indicate that DHH students benefit from morphological instruction to build their vocabulary knowledge in content-area classrooms, such as science courses.

Enhancing Teacher and Student Engagement and Understanding of Marine Science Through Classroom Citizen Science Projects

Goodale, T. A.

2016-02-01

Overview This paper presentation shares findings from a granted funded project that sought to expand teacher content knowledge and pedagogy within the fields of marine science and coastal resource management through the implementation of classroom citizen science projects. A secondary goal was to increase middle and high school student interest and participation in marine science and natural resources research. Background A local science & engineering fair has seen a rapid decline in secondary student participants in the past four years. Research has demonstrated that when students are a part of a system of knowledge production (citizen science) they become much more aware, involved and conscious of scientific concepts compared to traditional school laboratory and nature of science activities. This project's primary objectives were to: (a) enhance teacher content expertise in marine science, (b) enrich teacher professional learning, (c) support citizen science classroom projects and inspire student activism and marine science engagement. Methods Project goals were addressed through classroom and meaningful outdoor educational experiences that put content knowledge into field based practices. Teachers learned to apply thier expanded content knowlege through classroom citizen science projects that focus on marine resource conservation issues such as fisheries management, water quality, turtle nesting and biodiversity of coastal ecosystems. These projects would eventually become potential topics of citizen science research topics for their students to pursue. Upon completion of their professional development, participants were urged to establish student Marine Science clubs with the goal of mentoring student submissions into the local science fair. Supplemental awards were possible for the students of project participants. Findings Based on project measures participants significantly increased their knowledge and awareness of presented material marine science and coastal resources. 11/14 teacher participants established citizen science clubs that focused on marine related issues. Science fair participation increased by 42% and of those students whose mentor teacher was a project participant 90% stated they would likely pursue a marine science related major in college.

This pilot study investigates the impact of a 2-week professional development Summer Institute on PK-3 teachers' knowledge and practices. This Summer Institute is a component of [program], a large-scale early-childhood science project that aims to transform PK-3 science teaching. The mixed-methods study examined concept maps, lesson plans, and classroom observations to measure possible changes in PK-3 teachers' science content knowledge and classroom practice from 11 teachers who attended the 2014 Summer Institute. Analysis of the concept maps demonstrated statistically significant growth in teachers' science content knowledge. Analysis of teachers' lesson plans demonstrated that the teachers could design high quality science inquiry lessons aligned to the Next Generation Science Standards following the professional development. Finally, examination of teachers' pre- and post-Summer Institute videotaped inquiry lessons showed evidence that teachers were incorporating new inquiry practices into their teaching, especially regarding classroom discourse. Our results suggest that an immersive inquiry experience is effective at beginning a shift towards reform-aligned science and engineering instruction but that early elementary educators require additional support for full mastery.

A house divided: cooperative and competitive recruitment in vital industries.

Willis, William K; Muslin, Ivan; Timko, Karlyn N

2016-03-01

To propose a theoretical based model approach to address the nursing shortage problem of recruiting qualified applicants. Vital industries such as nursing and trucking face a large labour shortage. A literature review focusing on recruitment and realistic job previews examines relevant theories and an indication of the focus of similar research. Game theory illustrates cooperative and competitive recruitment strategies in vital industries. Proposition and model development where cooperative or competitive strategies for recruitment can either increase or decrease the employee applicant pool. Institutional theory states that firms within a population become isomorphic in nature. Firms employing cooperative or competitive strategies for recruitment can change organisational practices through isomorphic processes. Industries facing a labour market shortage using cooperative strategy will use realistic job previews accurately to disseminate information about industry jobs. Realistic job previews will increase the applicant pool through individuals self-selecting into, rather than out of, the applicant pool. Recruitment in the nursing industry has been examined at the individual applicant and organisational level, yet the overall industry has been ignored. As nursing shortages continue, viewing recruitment at the macro level (the overall industry) is appropriate. Game theory as proposed provides opportunities for current research at the industry level. © 2015 John Wiley & Sons Ltd.

Intuitive Exploration of Volumetric Data Using Dynamic Galleries.

PubMed

Jönsson, Daniel; Falk, Martin; Ynnerman, Anders

2016-01-01

In this work we present a volume exploration method designed to be used by novice users and visitors to science centers and museums. The volumetric digitalization of artifacts in museums is of rapidly increasing interest as enhanced user experience through interactive data visualization can be achieved. This is, however, a challenging task since the vast majority of visitors are not familiar with the concepts commonly used in data exploration, such as mapping of visual properties from values in the data domain using transfer functions. Interacting in the data domain is an effective way to filter away undesired information but it is difficult to predict where the values lie in the spatial domain. In this work we make extensive use of dynamic previews instantly generated as the user explores the data domain. The previews allow the user to predict what effect changes in the data domain will have on the rendered image without being aware that visual parameters are set in the data domain. Each preview represents a subrange of the data domain where overview and details are given on demand through zooming and panning. The method has been designed with touch interfaces as the target platform for interaction. We provide a qualitative evaluation performed with visitors to a science center to show the utility of the approach.

Effects of word predictability and preview lexicality on eye movements during reading: A comparison between young and older adults.

PubMed

Choi, Wonil; Lowder, Matthew W; Ferreira, Fernanda; Swaab, Tamara Y; Henderson, John M

2017-05-01

Previous eye-tracking research has characterized older adults' reading patterns as "risky," arguing that compared to young adults, older adults skip more words, have longer saccades, and are more likely to regress to previous portions of the text. In the present eye-tracking study, we reexamined the claim that older adults adopt a risky reading strategy, utilizing the boundary paradigm to manipulate parafoveal preview and contextual predictability of a target word. Results showed that older adults had longer fixation durations compared to young adults; however, there were no age differences in skipping rates, saccade length, or proportion of regressions. In addition, readers showed higher skipping rates of the target word if the preview string was a word than if it was a nonword, regardless of age. Finally, the effect of predictability in reading times on the target word was larger for older adults than for young adults. These results suggest that older adults' reading strategies are not as risky as was previously claimed. Instead, we propose that older adults can effectively combine top-down information from the sentence context with bottom-up information from the parafovea to optimize their reading strategies.

Renegotiating the pedagogic contract: Teaching in digitally enhanced secondary science classrooms

NASA Astrophysics Data System (ADS)

Ajayi, Ajibola Oluneye

This qualitative case study explores the effects of emerging digital technology as a teaching and learning tool in secondary school science classrooms. The study examines three teachers' perspectives on how the use of technology affects the teacher-student pedagogic relationship. The "pedagogic contract" is used as a construct to analyze the changes that took place in these teachers' classrooms amid the use of this new technology. The overarching question for this research is: How was the pedagogic contract renegotiated in three secondary science teachers' classrooms through the use of digitally enhanced science instruction. To answer this question, data was collected via semi-structured teacher interviews, classroom observations, and analysis of classroom documents such as student assignments, tests and Study Guides. This study reveals that the everyday use of digital technologies in these classrooms resulted in a re-negotiated pedagogic contract across three major dimensions: content of learning, method and management of learning activities, and assessment of learning. The extent to which the pedagogic contract was renegotiated varied with each of the teachers studied. Yet in each case, the content of learning was extended to include new topics, and greater depth of learning within the mandated curriculum. The management of learning was reshaped around metacognitive strategies, personal goal-setting, individual pacing, and small-group learning activities. With the assessment of learning, there was increased emphasis on self-directed interactive testing as a formative assessment tool. This study highlights the aspects of science classrooms that are most directly affected by the introduction of digital technologies and demonstrates how those changes are best understood as a renegotiation of the teacher-student pedagogic contract.

Self-directed versus traditional classroom training for neonatal resuscitation.

PubMed

Weiner, Gary M; Menghini, Karin; Zaichkin, Jeanette; Caid, Ann E; Jacoby, Carrie J; Simon, Wendy M

2011-04-01

Neonatal Resuscitation Program instructors spend most of their classroom time giving lectures and demonstrating basic skills. We hypothesized that a self-directed education program could shift acquisition of these skills outside the classroom, shorten the duration of the class, and allow instructors to use their time to facilitate low-fidelity simulation and debriefing. Novice providers were randomly allocated to self-directed education or a traditional class. Self-directed participants received a textbook, instructional video, and portable equipment kit and attended a 90-minute simulation session with an instructor. The traditional class included 6 hours of lectures and instructor-directed skill stations. Outcome measures included resuscitation skill (megacode assessment score), content knowledge, participant satisfaction, and self-confidence. Forty-six subjects completed the study. There was no significant difference between the study groups in either the megacode assessment score (23.8 [traditional] vs 24.5 [self-directed]; P = .46) or fraction that passed the "megacode" (final skills assessment) (56% [traditional] vs 65% [self-directed]; P = .76). There were no significant differences in content knowledge, course satisfaction, or postcourse self-confidence. Content knowledge, years of experience, and self-confidence did not predict resuscitation skill. Self-directed education improves the educational efficiency of the neonatal resuscitation course by shifting the acquisition of cognitive and basic procedural skills outside of the classroom, which allows the instructor to add low-fidelity simulation and debriefing while significantly decreasing the duration of the course.

Digital immigrants teaching digital natives: A phenomenological study of higher education faculty perspectives on technology integration with English core content

NASA Astrophysics Data System (ADS)

Corey, Robert C.

In the last two decades, technology use has escalated and educators grapple with its advances and integration into the classroom. Issues surrounding what constitutes a literate society, the clarion calls for educational reform emanating from US presidents to parent teacher organizations, and educators' ability to cope with advances in technology in the classroom demand attention. Therefore, the purpose of this qualitative study was to explore and understand the professional and educational experiences of six English faculty members teaching undergraduate courses at Midwest universities. Using the framework of Technological Pedagogical Content Knowledge -- TPACK (Koehler and Mishra 2008), the major focus of the study was to determine how faculty members understood what characterized the nature of teaching with technology in undergraduate classrooms. Results of this study revealed five themes showing how the participants were introduced to technology, how they assimilated it into their pedagogy, and how they integrated it into teaching practice. This study has the potential to impact the nature of illustrating the methods and techniques used by the six participants as they merge technology, pedagogy, and content knowledge and set in motion classroom practices that assist faculty at all levels to develop and teach technology skills necessary for the 21st century and to better prepare students for thinking critically about how to use digital advances.

The effects of departmentalized and self-contained classrooms on fifth-grade students' achievement in science on the Georgia Criterion Referenced Competency Test

NASA Astrophysics Data System (ADS)

Koch, Lisa S.

Elementary instruction of fifth grade classrooms was found to be primarily in two organizational models in a school district northwest of Atlanta, Georgia. The self-contained classroom provided a generalist teacher responsible for the instruction of all academic subjects to one group of students throughout the day, while departmentalized classrooms were structured utilizing one teacher for the instruction of one or two content areas, and students rotated throughout the day for each of the academic subjects. The majority of studies looking at the effect of instructional organization were concentrated in the content areas of mathematics and reading. This quantitative study, utilized an ex post facto methodology to determine whether fifth grade students attending departmentalized schools or self-contained classrooms had higher student achievement in science as measured by the Georgia Criterion Referenced Competency Test (CRCT). The statistical data was collected through the Georgia Department of Education and included raw mean scores of over 500 students attending departmentalized schools and 500 students attending self-contained classrooms, along with the various subgroups such as gender, ethnicity status, English language learners (ELL), and students with disability (SWD) placement. This data was analyzed to show if a significant statistical difference emerged from either instructional organization. The overall results that emerged from the archival data suggested no significant difference in student achievement existed for almost all subgroups tested of the total 1000+ participant scores used in the study. The results also did however, showed the departmentalization model of instruction had a slight advantage over self-contained classrooms for male students with disabilities.

Effects of interactive technology, teacher scaffolding and feedback on university students' conceptual development in motion and force concepts

NASA Astrophysics Data System (ADS)

Stecklein, Jason Jeffrey

The utilization of interactive technologies will affect learning in science classrooms of the future. And although these technologies have improved in form and function, their effective employment in university science classrooms has lagged behind the rapid development of new constructivist pedagogies and means of instruction. This dissertation examines the enlistment of instructional technologies, in particular tablet PCs and DyKnow Interactive Software, in a technologically enhanced, university-level, introductory physics course. Results of this qualitative case study of three university students indicate that (1) the use of interactive technology positively affects both student learning within force and motion and self-reported beliefs about physics, (2) ad hoc use of instructional technologies may not sufficient for effective learning in introductory physics, (3) student learners dictate the leveraging of technology in any classroom, and (4) that purposeful teacher structuring of classroom activities with technologies are essential for student construction of knowledge. This includes designing activities to elicit attention and make knowledge visible for low-level content, while augmenting student interactions and modelling procedural steps for higher-level content.

An Investigation of Science Teaching Practices in Indonesian Rural Secondary Schools

NASA Astrophysics Data System (ADS)

Wahyudi; Treagust, David F.

2004-08-01

This study reports on teaching practices in science classrooms of Indonesian lower secondary schools in rural areas. Using six schools from three districts in the province of Kalimantan Selatan as the sample, this study found that most teaching practices in science classrooms in rural schools were teacher-centred with students copying notes. However, the study also found unique teaching practices of an exemplary science teacher whose teaching style can be described as both student-centred and teacher-centred, with students encouraged to be active learners. Four features of exemplary teaching practices were identified: The teacher managed the classroom effectively; used a variety of questioning techniques; employed various teaching approaches instead of traditional methods; and created a favourable learning environment. Data from classroom observations, interviews with teachers, and students responses to a questionnaire were used to compare the exemplary teacher and his colleagues. This study identified internal factors that may affect teaching practices such as a teachers content knowledge and beliefs about teaching. Compared to the other teachers, the exemplary teacher possessed more content knowledge and had a relatively stronger belief in his ability to teach.

Factors Influencing Science Content Accuracy in Elementary Inquiry Science Lessons

NASA Astrophysics Data System (ADS)

Nowicki, Barbara L.; Sullivan-Watts, Barbara; Shim, Minsuk K.; Young, Betty; Pockalny, Robert

2013-06-01

Elementary teachers face increasing demands to engage children in authentic science process and argument while simultaneously preparing them with knowledge of science facts, vocabulary, and concepts. This reform is particularly challenging due to concerns that elementary teachers lack adequate science background to teach science accurately. This study examined 81 in-classroom inquiry science lessons for preservice education majors and their cooperating teachers to determine the accuracy of the science content delivered in elementary classrooms. Our results showed that 74 % of experienced teachers and 50 % of student teachers presented science lessons with greater than 90 % accuracy. Eleven of the 81 lessons (9 preservice, 2 cooperating teachers) failed to deliver accurate science content to the class. Science content accuracy was highly correlated with the use of kit-based resources supported with professional development, a preference for teaching science, and grade level. There was no correlation between the accuracy of science content and some common measures of teacher content knowledge (i.e., number of college science courses, science grades, or scores on a general science content test). Our study concluded that when provided with high quality curricular materials and targeted professional development, elementary teachers learn needed science content and present it accurately to their students.

Primary school teachers' use of digital technology in mathematics: the complexities

NASA Astrophysics Data System (ADS)

Loong, Esther Yook-Kin; Herbert, Sandra

2018-02-01

This paper seeks to theorise primary teachers' degree of integration of digital technology in the mathematics classroom. In an age where digital technology use is ubiquitous, the issues surrounding teachers' choice, and ultimately their uptake of digital technologies in the classroom, is an area that need to be further unpacked. Cross-case analysis of the two teachers' uptake of digital technologies in their classroom, their pedagogical approaches and the reason for their choices provide insight into teachers' technological, pedagogical and content knowledge (TPACK). Differences in the way the teachers use digital technology in their classroom seem to be connected to their TPACK developmental stage.

Teaching the content in context: Preparing "highly qualified" and "high quality" teachers for instruction in underserved secondary science classrooms

NASA Astrophysics Data System (ADS)

Tolbert, Sara E.

2011-12-01

This dissertation research project presents the results of a longitudinal study that investigates the knowledge, beliefs, and practices of 13 preservice secondary science teachers participating in a science teacher credentialing/Masters program designed to integrate issues of equity and diversity throughout coursework and seminars. Results are presented in the form of three papers: The first paper describes changes in preservice teacher knowledge about contextualization in science instruction, where contextualization is defined as facilitating authentic connections between science learning and relevant personal, social, cultural, ecological, and political contexts of students in diverse secondary classrooms; the second paper relates changes in the self-efficacy and content-specific beliefs about science, science teaching, diversity, and diversity in science instruction; and the final paper communicates the experiences and abilities of four "social justice advocates" learning to contextualize science instruction in underserved secondary placement classrooms. Results indicate that secondary student teachers developed more sophisticated understandings of how to contextualize science instruction with a focus on promoting community engagement and social/environmental activism in underserved classrooms and how to integrate science content and diversity instruction through student-centered inquiry activities. Although most of the science teacher candidates developed more positive beliefs about teaching science in underrepresented classrooms, many teacher candidates still attributed their minority students' underperformance and a (perceived) lack of interest in school to family and cultural values. The "social justice advocates" in this study were able to successfully contextualize science instruction to varying degrees in underserved placement classrooms, though the most significant limitations on their practice were the contextual factors of their student teaching placements---in particular, the extent to which their cooperating teachers gave them the autonomy and planning time to design and implement their own activities and lessons. While the "integrated approach" to diversity and equity in science teacher education was, overall, successful in helping preservice teachers' move closer toward developing the beliefs, knowledge, and practices necessary for effective instruction in underserved classrooms, suggestions are given for increasing the effectiveness of the "integrated approach," particularly in the context of a one-year credentialing program.

An exploratory study of the influence of national and state standards on middle school science teachers' classroom assessment practices

NASA Astrophysics Data System (ADS)

McWaters, Kathy Jean

2001-07-01

Classroom assessment practices of middle school science teachers were identified and the influence of national and state science standards on these practices was examined. In Phase I of this study a mail questionnaire was sent to 450 middle school (grades 5,6,7 and 8) science teachers in 17 parishes in Louisiana to obtain information about their classroom assessment practices. In Phase II, nine middle school teachers in eight departmentalized classrooms, two classes at each grade, participated in a qualitative study. Data were collected through questionnaires, classroom observations, interviews and document analysis. Data analysis revealed three major categories of classroom assessment targets: (a) student achievement, (b) student attitudes and, (c) student products. Results indicated that most teachers are using different assessment methods when assessing different achievement targets, as recommended by science reform documents. It was also determined that many teachers are using appropriate methods to assess student learning. While teachers reported that students spend an inordinate amount of time engaged in assessment activities, classroom observations suggested that the activities were not always written tests or graded activities. Another key finding is that there is a disconnect between the quality of teaching and the quality of assessment. Teachers who teach the material recommended by science reform documents and use recommended instructional strategies were observed to stop teaching and engage students in a "test rehearsal" geared towards rote memorization of factual information. Data suggest that the national and state science content standards are influencing the content and the format of teacher-made tests. Teachers' reported using the standards during assessment construction or selection in a wide variety of ways. The most direct use of the standards reported was to select content, format and cognitive level for test items. A more circumspect approach used by teachers was to use the standards to write lesson plans and objectives and then to plan assessments based on these teacher-constructed objectives. Questionnaire data indicated that the three factors having the most influence on teachers' selection or construction of a particular type of assessment were: (a) how students learn, (b) alignment with state/district standards, and (c) purpose for assessment.

Microgravity vibration isolation: Optimal preview and feedback control

NASA Technical Reports Server (NTRS)

Hampton, R. D.; Knospe, C. R.; Grodsinsky, C. M.; Allaire, P. E.; Lewis, D. W.

1992-01-01

In order to achieve adequate low-frequency vibration isolation for certain space experiments an active control is needed, due to inherent passive-isolator limitations. Proposed here are five possible state-space models for a one-dimensional vibration isolation system with a quadratic performance index. The five models are subsets of a general set of nonhomogeneous state space equations which includes disturbance terms. An optimal control is determined, using a differential equations approach, for this class of problems. This control is expressed in terms of constant, Linear Quadratic Regulator (LQR) feedback gains and constant feedforward (preview) gains. The gains can be easily determined numerically. They result in a robust controller and offers substantial improvements over a control that uses standard LQR feedback alone.

The Effects of Incorporating Classroom Pets into the Fourth Grade Science Curriculum

NASA Astrophysics Data System (ADS)

Admire, Maegan

The purpose of this study was to identify and promote successful teaching strategies that incorporate classroom pets in order to influence student engagement, achievement, and perceptions of animals. This was a small action research study conducted in a fourth grade science classroom. Both quantitative and qualitative data were obtained including, pre- and post-assessments, student interviews, researcher field notes, researcher journal, and student work. The results of this study revealed an increased academic achievement from the pre- to post-assessment, increased student observations and descriptions when discussing the animals, and increased student empathy toward the animals. The results also revealed that the teacher's incorporation of the animals within the science curriculum grew in ease over time, and that the animals provided the educator with opportunities to teach non-content related lessons and also a concrete experience for the teacher to apply and extend the science content.

Teaching nursing concepts through an online discussion board.

PubMed

Hudson, Kandi Ann

2014-09-01

Barriers to course content engagement and student learning in nursing education abound. Some of these barriers include content overload, classroom time constraints, and large student numbers. One way to overcome these issues is the implementation of active learning strategies in the classroom. Despite the positive learning outcomes associated with active learning strategies described in the education literature, traditional passive learning strategies continue to be used by nurse educators in the classroom. This article details the results of a pilot study using an active teaching strategy—an online discussion board—which was designed to improve the learning engagement of beginning nursing students enrolled in their first face-to-face nursing course. The results of the semester-long pilot study indicated a favorable student response to the active teaching strategy and improved overall success in the course by the students who participated fully in the online discussions.

Interactive whiteboards in third grade science instruction

NASA Astrophysics Data System (ADS)

Rivers, Grier

Strategies have been put into place to affect improvement in science achievement, including the use of Interactive Whiteboards (IWBs) in science instruction. IWBs enable rich resources, appropriate pacing, and multimodal presentation of content deemed as best practices. Professional development experiences, use of resources, instructional practices, and changes in professional behavior in science teachers were recorded. Also recorded were differences in the engagement and motivation of students in IWB classrooms versus IWB-free classrooms and observed differences in students' problem solving, critical thinking, and collaboration. Using a mixed-method research design quantitative data were collected to identify achievement levels of the target population on the assumption that all students, regardless of ability, will achieve greater mastery of science content in IWB classrooms. Qualitative data were collected through observations, interviews, videotapes, and a survey to identify how IWBs lead to increased achievement in third grade classrooms and to develop a record of teachers' professional practices, and students' measures of engagement and motivation. Comparative techniques determined whether science instruction is more effective in IWB classroom than in IWB-free classrooms. The qualitative findings concluded that, compared to science teachers who work in IWB-free settings, elementary science teachers who used IWBs incorporated more resources to accommodate learning objectives and the varied abilities and learning styles of their students. They assessed student understanding more frequently and perceived their classrooms as more collaborative and interactive. Furthermore, they displayed willingness to pursue professional development and employed different engagement strategies. Finally, teachers who used IWBs supported more instances of critical thinking and problem-solving. Quantitative findings concluded that students of all ability levels were more motivated and engaged in IWB classes. Best practices distilled included combining IWBs with handheld peripherals to maximize assessment; the determination that formal professional development is more effective than peer coaching; that effectively managing an IWB classroom is as vital as learning how to use board itself; and that IWB teachers should be able to modify resources to tailor them for the circumstances of their classroom.

Students' beliefs, attitudes, and conceptual change in a traditional and a constructivistic high school physics classroom

NASA Astrophysics Data System (ADS)

Adams, April Dean

In this study, the relationships between student beliefs about the nature of science, student attitudes, and conceptual change about the nature of forces were investigated within a traditional and within a constructivistic high school physics classroom. Students in both classrooms were honors students taking a first year high school physics course and were primarily white and middle to upper SES. Students in the traditional classroom were all high ability juniors, and physics instruction was integrated with pre-calculus. Students in the constructivistic classroom were a mixture of juniors and seniors. Due to the interrelated nature of these factors and the complexity of their interactions, a naturalistic inquiry design was chosen. The data sources included videotape of 7-9 weeks of instruction; analysis of the videotapes using the Secondary Teacher Analysis Matrix (Gallagher & Parker, 1995); field notes; pretest/posttest assessment with the Force Concept Inventory (Hestenes, Wells, & Swackhammer, 1992); student responses from the Views on Science-Technology-Society questionnaire (Aikenhead & Ryan, 1992), the Questionnaire for the Assessment of a Science Course (Chiappetta, 1995), and the Constructivist Learning Environment Survey (Taylor, Fraser, & White, 1994); student interviews; and teacher interviews. In the traditional classroom, (a) students did not think that physics was relevant to everyday experiences; (b) high conceptual change students were more likely to have an angular world view (Cobern, 1993) and have views more similar to the teacher's about the nature of science; and (c) high conceptual change students were able to develop an internally consistent understanding of the content; however, that content appeared to be isolated knowledge in some students. In the constructivistic classroom, (a) students saw physics as relevant and useful; (b) there was no difference in world view or agreement with the teacher's views on the nature of science between high and low conceptual change students; (c) students appreciated the importance of empirical evidence; and (d) low conceptual change students had low classroom engagement. Mean gains in conceptual change were larger for the traditional classroom.

Family Life Goes On: Disability in Contemporary Families

PubMed Central

Farrell, Anne F.; Krahn, Gloria L.

2015-01-01

Disability is part of life for most contemporary families, but to date the literature on disability in families is fragmented and narrow. This editorial commentary introduces the content and findings of peer-reviewed articles appearing in a special issue of Family Relations. The editors outline unanswered but core research questions and preview the themes present in the issue: families with disabilities are diverse; economic hardship disproportionately characterizes their lives; family life with disabilities is a journey that includes stress and resilience, with support contributing significantly to the latter; and that work benefits and taxes family life. Articles extrapolate beyond findings to explore implications for family policy and practice. The editors assert that developing understanding of how disability influences families requires a more diverse and rigorous research portfolio. They further cite the need to embed disability as a variable in a range of family studies and advocate more outlets for publication. PMID:26185356

Chaotic....!! Active and Engaged. Effects of an active learning classroom on student retention and engagement.

Scientific literacy has been defined as the foremost challenge of this decade (AAAS, 2012). The Geological Society of American in its position statement postis that due to the systemic nature of the discipline of earth science, it is the most effective way to engage students in STEM disciplines. Given that the most common place for exposure to earth sciences is at the freshman level for non majors, we decided to transform a freshman introductory geology course to an active, student centered course, using an inquiry based approach. Our focus was to ensure the students saw the earth sciences as broadly applicative field, and not an esoteric science. To achieve this goal, we developed a series of problems that required the students to apply the concepts acquired through their self guided learning into the different topics of the course. This self guided learning took the form of didactic content uploaded into the learning management system (the various elements used to deliver the content were designed video clips, short text based lectures, short formative assessments, discussion boards and other web based discovery exercises) with the class time devoted to problem solving. A comparison of student performance in the active learning classroom vs. a traditional classroom as measured on a geoscience concept inventory (the questions were chosen by a third party who was not teaching either courses) showed that the the students in the active learning classroom scored 10% higher on the average in comparison to the traditional class. In addition to this heightened performance, the students in the active classroom also showed a higher degree of content retention 8 weeks after the semester had ended. This session will share the design process, some exercises and efficacy data collected.

The role of entomology in environmental and science education: Comparing outreach methods for their impact on student and teacher content knowledge and motivation

NASA Astrophysics Data System (ADS)

Weeks, Faith J.

Outreach programming can be an important way for local students and teachers to be exposed to new fields while enhancing classroom learning. University-based outreach programs are offered throughout the country, including most entomology departments as few individuals learn about insects in school and these programs can be excellent sources of entomological education, as well as models to teach environmental and science education. Each department utilizes different instructional delivery methods for teaching about insects, which may impact the way in which students and teachers understand the insect concepts presented. To determine the impact of using entomology to enhance science and environmental education, this study used a series of university-based entomology outreach programs to compare three of the most common delivery methods for their effect on teacher and student content knowledge and motivation, specifically student interest in entomology and teacher self-efficacy. Twenty fifth grade classrooms were assessed over the course of one school year. The results show that teacher knowledge significantly increased when teachers were unfamiliar with the content and when trained by an expert, and teacher self-efficacy did not decrease when asked about teaching with insects. For students, content knowledge increased for each lesson regardless of treatment, suggesting that outreach program providers should focus on working with local schools to integrate their field into the classroom through the delivery methods best suited to the needs of the university, teachers, and students. The lessons also had an impact on student interest in science and environmental education, with an overall finding that student interest increases when using insects in the classroom.

From teachers' perspective: Implementation of literacy materials in middle school science

NASA Astrophysics Data System (ADS)

Weingartner, Judith A.

Documentation of adolescents' difficulty in comprehending textbooks spans a century. For just as long, researchers have advocated that explicit instruction of reading strategies can help students' comprehension of text; many have recommended that the best place to teach these strategies is within the content classroom (science, math, etc.), and taught by the content teacher. Despite this research, reading strategy instruction in content classrooms is not a common occurrence. In a large district with 300 middle school science teachers, some science teachers expressed concern about their students' reading difficulties with the district's science text. In response to those concerns, the middle school science coordinator organized a small committee to develop the Reading Strategies Handbook for Middle School Science for Teachers (the Handbook), believing that this tool would guide teachers' in implementing the Handbook's reading strategies and improve students' comprehension of the text. This was a qualitative study that explored 11 middle school science teachers' responses to implementing the Handbook. Data for this study were gathered through an e-mailed questionnaire, a classroom visitation, and one interview with each teacher participant. The study found that teachers' varied backgrounds influenced their beliefs about teaching and learning, and impacted their classroom practices. Teachers faced their district's expectations to implement reading strategies in the Handbook with minimal support and cited influences beyond their control that created tension with their decision whether to implement the Handbook. Teachers commented that a "one size fits all" curriculum and textbook-specific issues influenced their degree of using the Handbook's reading strategies. In addition, teachers identified time and pressure to cover curriculum as obstacles to implementing the Handbook. Implications of these findings include: (a) Professional development studies related to content literacy are needed that include attention to teachers' beliefs and attitudes, and (b) Policy makers need to direct funding for the professional development needs of content-area teachers.

Evaluation of traditional classroom teaching methods versus course delivery via the World Wide Web.

Higher education is moving with deliberate speed to an electronic classroom. Much has been published on faculty experiences with World Wide Web (WWW) course delivery. However, little research exists on the evaluation of these methods. The purpose of this study was to evaluate students' perceptions of two approaches to teaching: classroom and WWW modules. Classroom methods were rated significantly higher in relation to content, interaction, participation, faculty preparation, and communication. Technical skills were rated higher for WWW modules. Critical thinking and time allotted for assignments were not significantly different between classroom and WWW instruction. Open-ended comments were rich and supported both positive and negative aspects of classroom and WWW-based modules. Implications call for creativity in course development, course redesign and orientation, active communication with students, support for technical problems, faculty development, and university-wide planning through partnerships.
