    Bellin, Robert M; Bruno, Mary K; Farrow, Melissa A

    2010-01-01

    We have developed a 9-week undergraduate laboratory series focused on the purification and characterization of Thermus aquaticus DNA polymerase (Taq). Our aim was to provide undergraduate biochemistry students with a full-semester continuing project simulating a research-like experience, while having each week's procedure focus on a single learning goal. The laboratory series has been taught for the past 7 years, and survey-based assessment of the effectiveness of the laboratory series was completed during the 2006 and 2007 fall semesters. Statistical analysis of the survey results demonstrate that the laboratory series is very effective in teaching students the theory and practice of protein purification and analysis while also demonstrating positive results in more broad areas of scientific skill and knowledge. Amongst the findings, the largest reported increases in knowledge were related to students' understanding of how patent law relates to laboratory science, a topic of great importance to modern researchers that is readily discussed in relation to Taq polymerase. Overall, this laboratory series proves to be a very effective component in the curricula of undergraduate biology and chemistry majors and may be an appropriate laboratory experience for undergraduates.

  9. Integrating responsible conduct of research education into undergraduate biochemistry and molecular biology laboratory curricula.

    PubMed

    Hendrickson, Tamara L

    2015-03-01

    Recently, a requirement for directed responsible conduct in research (RCR) education has become a priority in the United States and elsewhere. In the US, both the National Institutes of Health and the National Science Foundation require RCR education for all students who are financially supported by federal awards. The guidelines produced by these agencies offer useful templates for the introduction of RCR materials into courses worldwide. Many academic programs already offer courses or workshops in RCR for their graduate students and for undergraduate science majors and/or researchers. Introducing RCR into undergraduate biochemistry and molecular biology laboratory curricula is another, highly practical way that students can be exposed to these important topics. In fact, a strong argument can be made for integrating RCR into laboratory courses because these classes often introduce students to a scientific environment like that they might encounter in their careers after graduation. This article focuses on general strategies for incorporating explicit RCR education into biochemistry and molecular biology laboratory coursework using the topics suggested by NIH as a starting point. © 2015 by The International Union of Biochemistry and Molecular Biology, 43(2):68-75, 2015.

    A recent forensic approach for identification of unknown biological samples is mitochondrial DNA (mtDNA) sequencing. We describe a laboratory exercise suitable for an undergraduate biochemistry course in which the polymerase chain reaction is used to amplify a 440 base pair hypervariable region of human mtDNA from a variety of "crime scene" samples (e.g., teeth, hair, nails, cigarettes, envelope flaps, toothbrushes, and chewing gum). Amplification is verified via agarose gel electrophoresis and then samples are subjected to cycle sequencing. Sequence alignments are made via the program CLUSTAL W, allowing students to compare samples and solve the "crime."

  3. Using an ePortfolio system as an electronic laboratory notebook in undergraduate biochemistry and molecular biology practical classes.

    Johnston, Jill; Kant, Sashi; Gysbers, Vanessa; Hancock, Dale; Denyer, Gareth

    2014-01-01

    Despite many apparent advantages, including security, back-up, remote access, workflow, and data management, the use of electronic laboratory notebooks (ELNs) in the modern research laboratory is still developing. This presents a challenge to instructors who want to give undergraduate students an introduction to the kinds of data curation and notebook keeping skills that will inevitably be required as ELNs penetrate normal laboratory practice. An additional problem for the teacher is that ELNs do not generally have student-administrative functions and are prohibitively expensive. In this report, we describe the use and impact of an ePortfolio system as a surrogate ELN. Introduction of the system led to several pedagogic outcomes, namely: increased preparedness of students for class, encouragement of creativity and reflection with respect to experimental methods, greatly enhanced engagement between students and tutors, and it gave instructors the ability to scrutinize original data files and monitor student-tutor feedback cycles. However, implementation led to a disruption of tutor workloads and incurred new levels of accountability that threatened to undermine the initiative. Through course evaluations and other reflective processes, we reached an appreciation of how an ELN should be introduced into practical class teaching so that it not only becomes an appropriate aid for teaching the laboratory experience, but also becomes a life-long resource for students.

    1998-10-01

    Immobilized enzymes have many practical applications. They may be used in clinical, industrial, and biotechnological laboratories and in many clinical diagnostic kits. For educational purposes, use of immobilized enzymes can easily be taught at the undergraduate or even secondary level. We have developed an immobilized enzyme experiment that combines many practical techniques used in the biochemistry laboratory and fits within a three-hour time frame. In this experiment, lactase from over-the-counter tablets for patients with lactose intolerance is immobilized in polyacrylamide, which is then milled into small beads and placed into a chromatography column. A lactose solution is added to the column and the eluant is assayed using the glucose oxidase assay, available as a kit. We have determined the optimal conditions to give the greatest turnover of lactose while allowing the immobilized enzymes to be active for long periods at room temperature.

    1996-11-01

    The dilemma of designing an advanced undergraduate laboratory lies in the desire to teach and reinforce basic principles and techniques while at the same time exposing students to the excitement of research. We report here on a one-semester, project-based biochemistry laboratory that combines the best features of a cookbook approach (high success rate, achievement of defined goals) with those of an investigative, discovery-based approach (student involvement in the experimental design, excitement of real research). Individual modules may be selected and combined to meet the needs of different courses and different institutions. The central theme of this lab is protein purification and design. This laboratory accompanies the first semester of biochemistry (Structure and Function of Macromolecules, a course taken mainly by junior and senior chemistry and biological chemistry majors). The protein chosen as the object of study is the enzyme lysozyme, which is utilized in all projects. It is suitable for a student lab because it is easily and inexpensively obtained from egg white and is extremely stable, and its high isoelectric point (pI = 11) allows for efficient separation from other proteins by ion-exchange chromatography. Furthermore, a literature search conducted by the resourceful student reveals a wealth of information, since lysozyme has been the subject of numerous studies. It was the first enzyme whose structure was determined by crystallography (1). Hendrickson et al. (2) have previously described an intensive one-month laboratory course centered around lysozyme, although their emphasis is on protein stability rather than purification and engineering. Lysozyme continues to be the focus of much exciting new work on protein folding and dynamics, structure and activity (3 - 5). This lab course includes the following features: (i) reinforcement of basic techniques, such as preparation of buffers, simple enzyme kinetics, and absorption spectroscopy; (ii) experience with methods of protein purification; (iii) incorporation of appropriate controls into experiments; (iv) use of basic statistics in data analysis; (v) writing papers and grant proposals in accepted scientific style; (vi) peer review; (vii) oral presentation of results and proposals; and (viii) introduction to molecular modeling. Figure 1 illustrates the modular nature of the lab curriculum. Elements from each of the exercises can be separated and treated as stand-alone exercises, or combined into short or long projects. We have been able to offer the opportunity to use sophisticated molecular modeling in the final module through funding from an NSF-ILI grant. However, many of the benefits of the research proposal can be achieved with other computer programs, or even by literature survey alone. Figure 1.Design of project-based biochemistry laboratory. Modules (projects, or portions of projects) are indicated as boxes. Each of these can be treated independently, or used as part of a larger project. Solid lines indicate some suggested paths from one module to the next. The skills and knowledge required for protein purification and design are developed in three units: (i) an introduction to critical assays needed to monitor degree of purification, including an evaluation of assay parameters; (ii) partial purification by ion-exchange techniques; and (iii) preparation of a grant proposal on protein design by mutagenesis. Brief descriptions of each of these units follow, with experimental details of each project at the end of this paper. Assays for Lysozyme Activity and Protein Concentration (4 weeks) The assays mastered during the first unit are a necessary tool for determining the purity of the enzyme during the second unit on purification by ion exchange. These assays allow an introduction to the concept of specific activity (units of enzyme activity per milligram of total protein) as a measure of purity. In this first sequence, students learn a turbidimetric assay for lysozyme activity and a colorimetric one for protein concentration. Familiarity with the assay

    2014-01-01

    Encouraging undergraduate students to access, read, and analyze current primary literature can positively impact learning, especially in advanced courses. The incorporation of literature into coursework typically involves reading and responding to full research reports. Such exercises have clear value as students make connections between experiments and are able to probe and critique scientific logic. The exclusive use of full papers, though, may reinforce certain students' tendencies to rely on textual clues rather than a critical analysis of the actual data presented. I propose that structured activities requiring students to focus on individual parts of research papers, even on a single figure, are beneficial in a literature-centered advanced undergraduate course, because they promote the deep reading that is critical to scientific discourse. In addition, I describe how one such focused assignment boosted learning and was well received by students in a second-semester biochemistry course. PMID:24243802

  8. Undergraduate Laboratory for Surface Science

    NASA Astrophysics Data System (ADS)

    Okumura, Mitchio; Beauchamp, Jesse L.; Dickert, Jeffrey M.; Essy, Blair R.; Claypool, Christopher L.

    1996-02-01

    Surface science has developed into a multidisciplinary field of research with applications ranging from heterogeneous catalysis to semiconductor etching (1). Aspects of surface chemistry are now included in physical chemistry textbooks (2) and undergraduate curricula (3), but the perceived cost and complexity of equipment has deterred the introduction of surface science methods in undergraduate laboratories (4). Efforts to expose chemistry undergraduates to state-of-the-art surface instrumentation have just begun (5). To provide our undergraduates with hands-on experience in using standard techniques for characterizing surface morphology, adsorbates, kinetics, and reaction mechanisms, we have developed a set of surface science experiments for our physical chemistry laboratory sequence. The centerpiece of the laboratory is an ultrahigh vacuum (UHV) chamber for studies of single crystal surfaces. This instrument, shown in the figure, has surface analysis capabilities including low energy electron diffraction (LEED), Auger spectroscopy, and temperature-programmed desorption (TPD). The laboratory exercises involve experiments on the well-studied Pt(111) surface. Students prepare a previously mounted single crystal sample by sputtering it with an argon ion gun and heating it under O2. Electron diffraction patterns from the cleaned surface are then obtained with a reverse view LEED apparatus (Princeton Instruments). Images are captured by a charge-coupled device (CCD) camera interfaced to a personal computer for easy downloading and subsequent analysis. Although the LEED images from a Pt(111) surface can be readily interpreted using simple diffraction arguments, this lab provides an excellent context for introducing Miller indices and reciprocal lattices (6). The surface chemical composition can be investigated by Auger spectroscopy, using the LEED apparatus as a simple energy analyzer. The temperature programmed desorption experiment, which is nearly complete, will be be added to the curriculum this academic year. This experiment introduces students to the concepts of surface adsorption and desorption kinetics. The sample mount can be both heated to 900 oC and cooled by liquid nitrogen, allowing the study of the desorption of a variety of adsorbates, both chemisorbed and physisorbed. Adsorbed species evolving from the heated surface are detected with a quadrupole mass spectrometer. Initially, students will study the desorption kinetics of CO from a Pt(111) surface for a range of coverages and temperature programming rates in order to obtain rate parameters and to test the validity of Redhead's relationship between the activation energy of desorption and the peak desorption temperature. They then will be introduced to the mechanisms of surface reactions (Langmuir-Hinshelwood) in a study of CO oxidation on this surface. We have also set up a scanning tunneling microscopy (STM) laboratory using a commercially available instrument (Burleigh Instruments, Inc.), which complements the UHV surface structure experiments by introducing the topography of a real surface, for example, with steps and defect sites. With the apparatus now completed, we can explore other possible developments, for example, an applied physics track designed around experiments on semiconductor substrates. Future additions include X-ray photoelectron spectroscopy and completion of a separate surface infrared spectroscopy experiment on supported catalysts.

  15. Argumentation in undergraduate chemistry laboratories

    NASA Astrophysics Data System (ADS)

    Walker, Joi Phelps

    To address the need for reform in undergraduate science education a new instructional model called Argument-Driven Inquiry (ADI) was developed and then implemented in a undergraduate chemistry course at a community college in the southeastern United States (Sampson, Walker, & Grooms, 2009; Walker, Sampson, & Zimmerman, in press). The ADI instructional model is designed to give a more central place to argumentation and the role of argument in the social construction of scientific knowledge. This research investigated the growth in the quality of the student generated arguments and the scientific argumentation that took place over the course of a semester. Students enrolled in two sections of General Chemistry I laboratory at the community college participated in this study. The students worked in collaborative groups of three or four. The students were given a variation of the same performance task three times during the semester in order to measure individual ability to use evidence and justify their choice of evidence with appropriate rationale. Five ADI investigations took place during the semester and the laboratory reports for each were collected from each student and the argument section of each report was scored. All the student groups were video recorded five times during the semester as they generated and evaluated arguments and the quality of the group argumentation was assessed using an instrument called the Assessment of Scientific Argumentation in the Classroom (ASAC) observation protocol. As time was the independent variable in this study a repeated measure ANOVA was used to evaluate the significance of student improvement in each area (argumentation, written argument and performance task) over the course of the semester (Trochim, 1999). In addition, a multiple regression analysis was conducted to evaluate how well the ASAC scores predicted individual scores on both the performance task and the written arguments (Green & Salkind, 2005). There was significant growth over the course of the semester in all three measures, performance-based assessment, written argument and oral argumentation. There also was a significant correlation between written and oral arguments that was used to generate a linear model using oral argumentation as a predictor of written argument. The results of this suggest that the use of an integrated instructional model such as ADI can have a positive impact on the quality of the arguments students include in their investigation reports, the argumentation they engage in during lab activities, and their overall performance on tasks that require them to develop and support a valid conclusion with genuine evidence.

    van Arman, Scott A.; Thomsen, Marcus W.

    1997-01-01

    Undergraduate laboratories continue increasing the use of instrumentation in teaching. One technique that is growing in popularity is HPLC. We have designed a set of simple HPLC separations as part of an introductory set of projects that serve as an introduction to chromatography early in the organic course. We have introduced quantitative analysis to the common separation of analgesics so that students may identify the composition of an unknown commercial tablet. Derived from this system is a Ĺn adaptation of the well known separation of nucleosides by reversed-phase HPLC such that students can quantitatively identify the components of an unknown "RNA digest." Students must determine retention times and an instrumental response factor for each component. For both separations all components elute in × 6 min. and baseline separation is excellent. From the retention times of standard individual component samples the identity of each component in the sample can be ascertained. From the instrumental response factors of standard individual component samples the percent composition of each component can be calculated.

    2012-01-01

    In order to review the strengths and weaknesses of medical biochemistry practical curriculum for undergraduates and to generate ideas to improve it, a questionnaire was sent to 50 biochemistry faculty members selected (through simple random sampling method) from 42 medical colleges of Maharashtra, India. 39 responded to the questionnaire, representing a 78% response rate. The internal consistency of the questionnaire sections was found to be satisfactory (>0.7). The respondents did not agree that the ongoing curriculum was in alignment with learning outcomes (8%), that it encouraged active learning (28%), helped to apply knowledge to clinical situations (18%) and promoted critical thinking and problem solving skills (28%). There were a number of qualitative experiments that were rated 'irrelevant'. Qualitative and quantitative experiments related to recent advances were suggested to be introduced by the respondents. Checklists for the practicals and new curriculum objectives provided in the questionnaire were also approved. The results of the curriculum evaluation suggest a need for re-structuring of practical biochemistry curriculum and introduction of a modified curriculum with more clinical relevance. PMID:23277713

    1998-06-01

    At Georgia Southern University, we offer a sophomore-level introductory biochemistry course that is aimed at nutrition and chemistry education majors. The laboratory portion of this course has long lacked an experimental introduction to enzymes. We have developed a simple enzyme assay utilizing lactase enzyme from crushed LactAid tablets and a 5% lactose solution ("synthetic milk"). In the experiment, the students assay the activity of the enzyme on the "synthetic milk" at pHs of approximately 1, 6, and 8 with the stated goal of determining where lactose functions in the digestive tract. The activity of the lactase may be followed chromatographically or spectrophotometrically. The experiment, which is actually a simple pH assay, is easily implemented in allied health chemistry laboratory courses and readily lends itself to adaptation for more complex kinetic assays in upper-level biochemistry laboratory courses. The experimental details, including a list of required supplies and hints for implementation, are provided.

    PubMed Central

    Dabrowski, Katie M.; Castańo, Diego J.; Tartar, Jaime L.

    2013-01-01

    We developed a hands-on laboratory exercise for undergraduate students in which they can build and manipulate a neuron equivalent circuit. This exercise uses electrical circuit components that resemble neuron components and are easy to construct. We describe the methods for creating the equivalent circuit and how to observe different neuron properties through altering the structure of the equivalent circuit. We explain how this hands-on laboratory activity allows for the better understanding of this fundamental neuroscience concept. At the conclusion of this laboratory exercise, undergraduate students will be able to apply the principles of Ohm’s law, cable theory with regards to neurons, and understand the functions of resistance and capacitance in a neuron.

    Hepburn, Sophie; Banks, Rosamonde E; Thompson, Douglas

    2014-01-01

    Background: With the increasing drive for more and better disease biomarkers to underpin the stratified or personalised medicine agenda, clinical biochemistry laboratories should be ideally placed to play a major role in their translation into clinical practice. However, little is known about the current extent of biomarker-related research activity in UK National Health Service clinical biochemistry departments. Methods: In December 2010, an online questionnaire was sent to active UK members of the Association for Clinical Biochemistry (ACB) to determine the extent of their current research activity and involvement in protein biomarker discovery and translation, including an assessment of the awareness of proteomics. Results: A total of 198 eligible responses (19% response rate) was received from across the UK. Of a further 50 eligible people who responded to a follow-up for initial non-responders, most cited insufficient knowledge about the topic as the reason for non-response (24% total response rate). The results illustrate the highly skilled nature of the workforce with many having experience in a research environment (75%) with postgraduate qualifications. However, more than half spend <10% of their time undertaking research in their current role, and many (61%) would like to be more research active. Encouragingly, approximately a third were involved in biomarker discovery activities, even though for <10% of their time, with slightly more reporting involvement in biomarker translation. Conclusions: Although there are people with the necessary skills and desire to be involved in biomarker research in clinical biochemistry departments, their involvement is small, predominantly due to issues with capacity and resources. It is likely that the majority of biomarker programmes will therefore continue to be carried out by a small number of academic groups, hopefully with collaborative input from hospital laboratories.

  11. Experiences of Mentors Training Underrepresented Undergraduates in the Research Laboratory

    PubMed Central

    Prunuske, Amy J.; Wilson, Janelle; Walls, Melissa; Clarke, Benjamin

    2013-01-01

    Successfully recruiting students from underrepresented groups to pursue biomedical science research careers continues to be a challenge. Early exposure to scientific research is often cited as a powerful means to attract research scholars with the research mentor being critical in facilitating the development of an individual's science identity and career; however, most mentors in the biological sciences have had little formal training in working with research mentees. To better understand mentors’ experiences working with undergraduates in the laboratory, we conducted semistructured interviews with 15 research mentors at a public university in the Midwest. The interviewed mentors were part of a program designed to increase the number of American Indians pursuing biomedical/biobehavioral research careers and represented a broad array of perspectives, including equal representation of male and female mentors, mentors from underrepresented groups, mentors at different levels of their careers, and mentors from undergraduate and professional school departments. The mentors identified benefits and challenges in being an effective mentor. We also explored what the term underrepresented means to the mentors and discovered that most of the mentors had an incomplete understanding about how differences in culture could contribute to underrepresented students’ experience in the laboratory. Our interviews identify issues relevant to designing programs and courses focused on undergraduate student research. PMID:24006389

    2013-01-01

    Biochemistry and molecular biology (BMB) students should demonstrate proficiency in the foundational concepts of the discipline and possess the skills needed to practice as professionals. To ascertain the skills that should be required, groups of BMB educators met in several focused workshops to discuss the expectations with the ultimate goal of clearly articulating the skills required. The results of these discussions highlight the critical importance of experimental, mathematical, and interpersonal skills including collaboration, teamwork, safety, and ethics. The groups also found experimental design, data interpretation and analysiand the ability to communicate findings to diverse audience to be essential skills. To aid in the development of appropriate assessments these skills are grouped into three categories, 1) Process of Science, 2) Communication and Comprehension of Science, and 3) Community of Practice Aspects of Science. Finally, the groups worked to align these competencies with the best practices in both teaching and in skills assessment. PMID:24019246

  18. Taking a new biomarker into routine use--a perspective from the routine clinical biochemistry laboratory.

    PubMed

    Sturgeon, Catharine; Hill, Robert; Hortin, Glen L; Thompson, Douglas

    2010-12-01

    There is increasing pressure to provide cost-effective healthcare based on "best practice." Consequently, new biomarkers are only likely to be introduced into routine clinical biochemistry departments if they are supported by a strong evidence base and if the results will improve patient management and outcome. This requires convincing evidence of the benefits of introducing the new test, ideally reflected in fewer hospital admissions, fewer additional investigations and/or fewer clinic visits. Carefully designed audit and cost-benefit studies in relevant patient groups must demonstrate that introducing the biomarker delivers an improved and more effective clinical pathway. From the laboratory perspective, pre-analytical requirements must be thoroughly investigated at an early stage. Good stability of the biomarker in relevant physiological matrices is essential to avoid the need for special processing. Absence of specific timing requirements for sampling and knowledge of the effect of medications that might be used to treat the patients in whom the biomarker will be measured is also highly desirable. Analytically, automation is essential in modern high-throughput clinical laboratories. Assays must therefore be robust, fulfilling standard requirements for linearity on dilution, precision and reproducibility, both within- and between-run. Provision of measurements by a limited number of specialized reference laboratories may be most appropriate, especially when a new biomarker is first introduced into routine practice. PMID:21137030

    Purpose: The medical education is recently being transformed into several domains in order to adapt to the need and the value based academics which is required for the quality doctors who serve the community. Presently, the biochemistry curricula for the graduate students of medicine have been questioned by as many experts, because of their multiple lacunae. In this review, we would like to highlight the scenario which is related to the existing biochemistry curricula for graduate medical students, which have been followed in several medical schools and universities and we also hope to share our ideas for implementing objective and pragmatic curricula. Evidence based research, wherein the articles which are related to innovative teaching-learning tools are collected and the pros and cons which are related to the different methods analyzed in biochemistry point of view. Conclusion: Rapid changes in the content of the curriculum may not be required, but a gradual introduction of the novel approach and the methods of teaching biochemistry can be adopted into the curriculum.

    2009-09-01

    Biological field stations and marine laboratories (FSMLs) serve as places to study the natural environment in a variety of ways, from the level of the molecule to the globe. Undergraduate opportunities at FSMLs reflect the diversity of study optionsâ??formal courses, research and service internships, and field-trip experiencesâ??and students are responding to those opportunities: More than half of the FSMLs that responded to an informal survey indicated an increase in their undergraduate enrollment in the past 10 years. Many programs are residential in nature, which facilitates the development of a community of scholars in which undergraduates can interact not just with their peers but also with graduate students, research assistants, postdoctoral fellows, and resident and visiting faculty. With respect to undergraduates, challenges for FSMLs include maintaining relevance in curricular offerings, attracting rigorous and well-trained instructors, providing adequate numbers of mentors for research experiences, and providing funding to assist undergraduates who want to study at a FSML.

    This paper describes an exercise in a Systems and Behavioral Neuroscience with Laboratory class, an introductory laboratory class taken by Barnard College students majoring in a wide range of academic topics. The study took place over three weeks, allowing students to assess the effects of caffeine on motor stimulation in laboratory rats. The within-subject design involved injecting rats with three different caffeine doses and measuring five different motor outputs in a standard open field. Students completed four different assignments related to this study, demonstrating acquisition of the stated learning goals. This lab exercise allowed students to learn about basal ganglia neural circuitry and stimulant pharmacology, to work directly with an animal model, and to generate enough data to perform statistical analyses. Course evaluations suggest that students liked learning about caffeine, a stimulant many of them have personal experience consuming. They also expressed appreciation for working with rats and for learning how to analyze data. This study can easily be implemented at most undergraduate institutions under minimal cost. The wide-ranging effects of caffeine also permit for flexibility in experimental design, allowing instructors and students options for different avenues of investigation. PMID:23504612

  16. Structural Studies of Phycobiliproteins from Spirulina: Combining Spectroscopy, Thermodynamics, and Molecular Modeling in an Undergraduate Biochemistry Experiment

    NASA Astrophysics Data System (ADS)

    Taylor, Ann T. S.; Feller, Scott E.

    2002-12-01

    Molecular modeling provides a powerful mechanism for students to connect molecular-level structural changes with macroscopically observable properties. We describe an experiment that integrates spectroscopy, thermodynamics, and molecular modeling into a single activity examining structural changes in phycobiliproteins upon denaturation with urea. Phycobiliproteins contain a covalently attached chromophore, phycocyanobilin, which is constrained in a planar conformation by the folded protein. Upon denaturation of the protein, the chromophore undergoes a conformational change, leading to a significant alteration of the absorption spectrum. By measuring the absorbance at 625 nm as a function of urea concentration, the free energy of unfolding can be determined. Students determine the dihedral angles in the chromophore and map the contacts between protein and chromophore using Protein Explorer, a structure visualization program freely available on the Internet. The change in absorption wavelength can be related to the difference between the LUMO and HOMO energies, obtained using PC Spartan Pro, for the chromophore in the folded and unfolded phycobiliprotein. This experiment could be used in a physical chemistry class in a curriculum that integrates biochemistry throughout the course work as well as in a traditional biochemistry course.

  11. Study of Polymer Glasses by Modulated Differential Scanning Calorimetry in the Undergraduate Physical Chemistry Laboratory

    NASA Astrophysics Data System (ADS)

    Folmer, J. C. W.; Franzen, Stefan

    2003-07-01

    Recent technological advances in thermal analysis present educational opportunities. In particular, modulated differential scanning calorimetry (MDSC) can be used to contrast reversing and nonreversing processes in practical laboratory experiments. The introduction of these concepts elucidates the relationship between experimental timescales and reversibility. The latter is a key concept of undergraduate thermodynamics theory that deserves reinforcement. In this paper, the theory and application of MDSC to problems of current interest is outlined with special emphasis on the contrast between crystallization and vitrification. Glass formation deserves greater emphasis in the undergraduate curriculum. Glass transitions are increasingly recognized as an important aspect of materials properties and dynamics in fields ranging from polymer science to protein folding. The example chosen for study is a comparison of polyethylene glycol and atactic polypropylene glycol. The experiment is easily performed in a typical three-hour lab session.

  13. The design, enactment, and impact of an undergraduate, inquiry-based, astronomy laboratory learning environment

    NASA Astrophysics Data System (ADS)

    Stewart, Steven A.

    This study investigated the design, enactment, and impact of an undergraduate, inquiry-based astronomy laboratory learning environment. The professor, Richard, adopted laboratory materials from the Center for Astronomy and Physics Education Research [CAPER] which were described by the group as inquiry-based. Students worked through these laboratory materials under the supervision of teaching assistants [TAs], and Richard led weekly TA meetings to monitor and instruct the TAs on his expectations. This study suggests that Richard was unsure of laboratory materials' learning goals and had received limited guidance on how to use and implement CAPER's materials. TAs also received limited guidance on how to interact with their students while they worked through the laboratory materials. TAs gave introductions during laboratory sessions that were similar to Richard's introductions given during weekly TA meetings. Data from this study suggests that most students were able to easily complete the laboratory materials without the assistance of their TA. When students did ask questions, questions were focused on obtaining the correct answer which TAs normally supplied though direct responses or questioning. This laboratory learning environment was found to have no impact on students' understanding of the nature of scientific inquiry, as measured by VOSI, which contradicts previous research findings associated with the materials. I suggest that professors should be cautious when adopting curriculum materials. Curriculum designers should provide information related to the design of their materials, the learning goals of those materials, sample student responses, and effective implementation strategies.

  18. Biochemistry and metabolism of lake trout: laboratory and field studies on the effects of contaminants

    USGS Publications Warehouse

    Passino, Dora R. May

    1981-01-01

    To evaluate the effects of ambient and higher concentrations of PCB's (Aroclor 1254) and DDE in food and water on fry of lake trout (Salvelinus namaycush) from Lake Michigan, I measured several biochemical indicators of stress in exposed and unexposed (control) fry. No differences between treatments were observed in oxygen consumption rates or lactate concentrations of unexercised fry, but apparent differences in specific swimming speed and lactate response in fry that swam to exhaustion suggested that exposed fry had lower stamina. Observed differences between biochemical profiles of 1-day-old sac fry reared from eggs originating from lake trout collected off Saugatuck and those originating from eggs of brood stock at the Marquette (Michigan) hatchery may have been caused by organochlorine contamination or by genetic and dietary differences between the parental stocks. Activity of the enzyme allantoinase was measured in juvenile and adult lake trout as an indicator of sublethal effects of Great Lakes contaminants. The 50% inhibition of allantoinase in vitro occurred at 6.0 mg/L Cu++, 6.7 mg/L Cd++, 34 mg/L Hg++, and 52 mg/L Pb++. Allantoinase was not affected by in vitro exposure to PCB's up to 7 ?g/g, or DDE or DDT up to 10 ?g/g; however, in vivo exposure resulting in 2.6 ?g/g PCB's in the whole fish activated allantoinase slightly (10% significance level). Allantoinase activity was negatively correlated with total length for fish from Lake Michigan but not for fish from Lake Superior or from laboratory stocks. Mercury, PCB's, and DDT, possibly acting in combination with each other and with additional contaminants, may be the cause of the negative correlation of allantoinase activity with size in Lake Michigan lake trout.

    NASA Astrophysics Data System (ADS)

    Gilles de Pelichy, Laurent D.; Adam, Carl; Smith, Eugene T.

    1997-10-01

    An undergraduate atomic absorption spectroscopy (AAS) laboratory experiment is presented involving the analysis of the essential nutrient strontium in a real-life sample, sea water. The quantitative analysis of strontium in sea water is a problem well suited for an undergraduate analytical chemistry laboratory. Sea water contains numerous components which prevent the direct quantitative determination of strontium. Students learn first hand about the role of interferences in analytical measurements, and about the method of standard addition which is used to minimize these effects. This laboratory exercise also introduces undergraduate students to practical problems associated with AAS. We encourage students as a part of this experiment to collect and analyze marine water samples from local pet shops.

    Wright, Shirley J

    2012-01-01

    Several programs in health professional education require or are considering requiring upper-level human anatomy as prerequisite for their applicants. Undergraduate students are confronted with few institutions offering such a course, in part because of the expense and logistical issues associated with a cadaver-based human anatomy course. This study describes the development of and student reactions to an upper-level human anatomy laboratory course for undergraduate students that used a regional approach and contemporary, alternative teaching methods to a cadaver-based course. The alternative pedagogy to deliver the curriculum included use of commercially available, three-dimensional anatomical virtual dissection software, anatomical models coupled with a learning management system to offer Web-based learning, and a new laboratory manual with collaborative exercises designed to develop the student's anatomical skills and collaborative team skills. A Likert-scale survey with open-ended questions was used to ascertain student perceptions of the course and its various aspects. Students perceived that the noncadaver-based, upper-level human anatomy course with an engaging, regional approach is highly valuable in their learning of anatomy. anatomy. PMID:22362500

    NASA Astrophysics Data System (ADS)

    Hudgins, Susan; Qin, Yu; Bakker, Eric; Shannon, Curtis

    2003-11-01

    Handheld computers provide a compact and cost-effective means to log data in the undergraduate chemistry laboratory. Handheld computers have the ability to record multiple forms of data, be programmed for specific projects, and later have data transferred to a personal computer for manipulation and analysis. They are more affordable than notebook computers and are more widely applicable than programmable calculators. This study focuses on acid base titration experiments that are commonly used in introductory chemistry courses. We wrote an interactive Basic language program that allowed a Palm device to measure pH during the course of a titration, and we used a compatible interface for the data acquisition, which we found to record accurate voltage measurements. After synchronizing the device to a laboratory workstation, the experimental data could be transferred into a spreadsheet file, viewed in graphical form and analyzed. Many other applications of handheld computers in the laboratory are possible with the ability to write individual programs on a handheld device. Therefore, the Palm's size, ease of use, and affordability make it an attractive alternative to previous data acquisition methods for use in the chemical laboratory.

    2005-12-01

    Active participation in independent research that begins with data collection at sea has been shown to significantly increase undergraduate interest toward pursuing a career in ocean science. Thirty-five undergraduate students have recently enrolled in one of four NSF-sponsored Transect Programs at the College of Charleston. Each multi-disciplinary program consisted of an intensive 5-day research cruise, followed by a rigorous semester Oceanographic Research course in which students learned laboratory techniques for analyzing the biological, physical and geological samples collected. Students also conducted individual research, presented their results at both a poster and oral session, and prepared a manuscript following journal guidelines. Students showed significant comprehension of their research results and interest in continuing their research. Student applications to jobs, graduate schools, scholarships and internships have shown greater than 90% acceptance rate. The program's next phase will include expansion to numerous institutions in the southeast and elsewhere, coordinating with coastal and ocean observatory networks while training a new generation of oceanographers.

  17. Promoting Professional Development in Undergraduate Engineering Using Laboratory Team Projects: A Case Study

    NSDL National Science Digital Library

    Davis, Gregory

    Good professional communication skills and the ability to work in teams are critical skills demanded by engineering companies. Further, in order to maintain competitiveness and to work in the global marketplace, engineering companies are increasingly supporting the creation and use of professional standards that are developed by engineering societies. Unfortunately, many undergraduates have historically received little or no education regarding this aspect of engineering. This paper describes the efforts to provide students with laboratory-based projects which provide students with significant exposure to professional engineering standards and practices. These projects require the students to read professional standards that pertain to the particular topic under study and to operate vehicles while using professional automotive engineering tools.

  18. Transposing from the Laboratory to the Classroom to Generate Authentic Research Experiences for Undergraduates

    PubMed Central

    Burnette, James M.; Wessler, Susan R.

    2013-01-01

    Large lecture classes and standardized laboratory exercises are characteristic of introductory biology courses. Previous research has found that these courses do not adequately convey the process of scientific research and the excitement of discovery. Here we propose a model that provides beginning biology students with an inquiry-based, active learning laboratory experience. The Dynamic Genome course replicates a modern research laboratory focused on eukaryotic transposable elements where beginning undergraduates learn key genetics concepts, experimental design, and molecular biological skills. Here we report on two key features of the course, a didactic module and the capstone original research project. The module is a modified version of a published experiment where students experience how virtual transposable elements from rice (Oryza sativa) are assayed for function in transgenic Arabidopsis thaliana. As part of the module, students analyze the phenotypes and genotypes of transgenic plants to determine the requirements for transposition. After mastering the skills and concepts, students participate in an authentic research project where they use computational analysis and PCR to detect transposable element insertion site polymorphism in a panel of diverse maize strains. As a consequence of their engagement in this course, students report large gains in their ability to understand the nature of research and demonstrate that they can apply that knowledge to independent research projects.

  19. Towards the Standardization of a MATLAB-Based Control Systems Laboratory Experience for Undergraduate Students

    SciTech Connect

    Dixon, W.E.

    2001-03-15

    This paper seeks to begin a discussion with regard to developing standardized Computer Aided Control System Design (CACSD) tools that are typically utilized in an undergraduate controls laboratory. The advocated CACSD design tools are based on the popular, commercially available MATLAB environment, the Simulink toolbox, and the Real-Time Workshop toolbox. The primary advantages of the proposed approach are as follows: (1) the required computer hardware is low cost, (2) commercially available plants from different manufacturers can be supported under the same CACSD environment with no hardware modifications, (3) both the Windows and Linux operating systems can be supported via the MATLAB based Real-Time Windows Target and the Quality Real Time Systems (QRTS) based Real-Time Linux Target, and (4) the Simulink block diagram approach can be utilized to prototype control strategies; thereby, eliminating the need for low level programming skills. It is believed that the above advantages related to standardization of the CACSD design tools will facilitate: (1) the sharing of laboratory resources within each university (i.e., between departments) and (2) the development of Internet laboratory experiences for students (i.e., between universities).

    2014-01-01

    Threshold concepts (TCs) are concepts that, when mastered, represent a transformed understanding of a discipline without which the learner cannot progress. We have undertaken a process involving more than 75 faculty members and 50 undergraduate students to identify a working list of TCs for biochemistry. The process of identifying TCs for biochemistry was modeled on extensive work related to TCs across a range of disciplines and included faculty workshops and student interviews. Using an iterative process, we prioritized five concepts on which to focus future development of instructional materials. Broadly defined, the concepts are steady state, biochemical pathway dynamics and regulation, the physical basis of interactions, thermodynamics of macromolecular structure formation, and free energy. The working list presented here is not intended to be exhaustive, but rather is meant to identify a subset of TCs for biochemistry for which instructional and assessment tools for undergraduate biochemistry will be developed.

  14. Developing a New Experimental System for an Undergraduate Laboratory Exercise to Teach Theories of Visuomotor Learning

    PubMed Central

    Kasuga, Shoko; Ushiba, Junichi

    2014-01-01

    Humans have a flexible motor ability to adapt their movements to changes in the internal/external environment. For example, using arm-reaching tasks, a number of studies experimentally showed that participants adapt to a novel visuomotor environment. These results helped develop computational models of motor learning implemented in the central nervous system. Despite the importance of such experimental paradigms for exploring the mechanisms of motor learning, because of the cost and preparation time, most students are unable to participate in such experiments. Therefore, in the current study, to help students better understand motor learning theories, we developed a simple finger-reaching experimental system using commonly used laptop PC components with an open-source programming language (Processing Motor Learning Toolkit: PMLT). We found that compared to a commercially available robotic arm-reaching device, our PMLT accomplished similar learning goals (difference in the error reduction between the devices, P = 0.10). In addition, consistent with previous reports from visuomotor learning studies, the participants showed after-effects indicating an adaptation of the motor learning system. The results suggest that PMLT can serve as a new experimental system for an undergraduate laboratory exercise of motor learning theories with minimal time and cost for instructors. PMID:25565915

    2014-01-01

    We have developed and tested two linked but separable structured inquiry exercises using a set of Drosophila melanogaster GAL4 enhancer trap strains for an upper-level undergraduate laboratory methods course at Bucknell University. In the first, students learn to perform inverse PCR to identify the genomic location of the GAL4 insertion, using FlyBase to identify flanking sequences and the primary literature to synthesize current knowledge regarding the nearest gene.

    We have developed and tested two linked but separable structured inquiry exercises using a set of Drosophila melanogaster GAL4 enhancer trap strains for an upper-level undergraduate laboratory methods course at Bucknell University. In the first, students learn to perform inverse PCR to identify the genomic location of the GAL4 insertion, using FlyBase to identify flanking sequences and the primary literature to synthesize current knowledge regarding the nearest gene. In the second, we cross each GAL4 strain to a UAS-CD8-GFP reporter strain, and students perform whole mount CNS dissection, immunohistochemistry, confocal imaging, and analysis of developmental expression patterns. We have found these exercises to be very effective in teaching the uses and limitations of PCR and antibody-based techniques as well as critical reading of the primary literature and scientific writing.

    2003-10-01

    We describe the development and implementation of an undergraduate physics laboratory course based on National Instruments' LabVIEW application. LabVIEW, a graphical programming language, provides an intuitive interface with which to teach fundamental computer-based data acquisition techniques. To convey the importance of these techniques in modern experimental physics, during our course the students complete a variety of tasks and experiments based around LabVIEW virtual instruments that they have constructed. Furthermore, LabVIEW is a powerful signal processing and waveform analysis tool, it may be used to reinforce core physics concepts taught in an analytical fashion in other courses. Foremost among these is Fourier analysis. We discuss the efficacy of LabVIEW as a pedagogical tool in a number of Fourier-related areas. Other important pure and applied physics topics covered in our LabVIEW course and briefly described here include resonance, filtering and lock-in techniques, thermal diffusivity, chaos, and optical absorption in solids.

  19. Testing plastic deformations of materials in the introductory undergraduate mechanics laboratory

    NASA Astrophysics Data System (ADS)

    Romo-Kröger, C. M.

    2012-05-01

    Normally, a mechanics laboratory at the undergraduate level includes an experiment to verify compliance with Hooke's law in materials, such as a steel spring and an elastic rubber band. Stress-strain curves are found for these elements. Compression in elastic bands is practically impossible to achieve due to flaccidity. A typical experiment for the complete loading-unloading cycle is to subject a tubular object to torsion. This paper suggests simple experiments for studying properties concerning elasticity and plasticity in elements of common use, subjected to stretching or compression, and also torsion reinforcing. The experiments use plastic binders, rubber bands and metal springs under a moderate load. This paper discusses an experiment with an original device to measure torsion deformations as a function of applied torques, which permitted construction of the hysteresis cycle for a rubber hose and various tubes. Another experiment was designed to define the temporal recovery of a plastic spring with initial stretching. A simple mathematical model was developed to explain this phenomenon.

  20. The effects of inquiry instruction on student learning in technology-based undergraduate chemistry laboratories

    NASA Astrophysics Data System (ADS)

    Meade, Karen Marie

    The purpose of this study was to identify conceptual and attitudinal effects of inquiry learning in technology-based undergraduate chemistry laboratories. There were 428 participants who were registered in general chemistry laboratory at the University of Iowa in the Spring of 2002. Conceptual and attitudinal pretest and posttest results were quantitative in nature. Qualitative results were collected from questionnaires and focus groups. Quantitative data were analyzed using a repeated measures analysis of variance to identify differences between treatment groups. A high-inquiry treatment group was open-ended and required student decisions regarding data collection, data representation, and interpretation. The low-inquiry treatment involved collaboration and traditional learning strategies. Major findings of this study were: (1) Pretest to posttest conceptual gains were significant for both treatment groups. Low-inquiry students performed significantly better on exploration questions than high-inquiry students. (2) Process skills developed at higher levels for high-inquiry students than low-inquiry students. (3) Positive attitudes decreased significantly for all students from pretest to posttest. More favorable attitudes toward science enjoyment and the ability to do well in science were found for high-inquiry students. More favorable attitudes toward science enjoyment and the ability to do well in science were found for low-inquiry males and high-inquiry females. (4) More favorable attitudes toward the nature of science caused by use of the learning cycle were reported by high-inquiry students. (5) Low-inquiry students reported more favorable attitudes toward technologies in the laboratory than did high-inquiry students. Favorable attitudes toward the use of infrared spectrometers and unfavorable attitudes toward the use of pH meters were reported by both treatment groups. (6) More formal reasoning skills were reported by high-inquiry students. Both groups reported that looking for patterns was a common theme in the laboratories. Hypotheses were reported as rarely used by both treatment groups. These findings are significant because they indicate that inquiry activities positively affect attitudes toward science, gender equality, and contribute to the development of formal reasoning skills and process skills.

    An experiment is presented that demonstrates current techniques in modern RNA research and introduces a method for nonradioactive monitoring of RNA reactions. The laboratory involves the study of hammerhead ribozyme activity and the influence of metal ions and antibiotics on these important RNA-based reactions. The ribozyme class of RNA catalysts has current applications in both biotechnology and medicine and therefore should be of great interest to upper-level undergraduate students who anticipate careers in these areas. The students gain hands-on experience in working with RNA on a picomole level and also learn about gel electrophoresis, the use of fluorescent tagging, RNA-small molecule interactions, and the role of metal ions in biological systems. This laboratory offers students an opportunity to work with molecules that have direct applications in drug therapy and RNA catalysis.

    Genomics is not only essential for students to understand biology but also provides unprecedented opportunities for undergraduate research. The goal of the Genomics Education Partnership (GEP), a collaboration between a growing number of colleges and universities around the country and the Department of Biology and Genome Center of Washington University in St. Louis, is to provide such research opportunities. Using a versatile curriculum that has been adapted to many different class settings, GEP undergraduates undertake projects to bring draft-quality genomic sequence up to high quality and/or participate in the annotation of these sequences. GEP undergraduates have improved more than 2 million bases of draft genomic sequence from several species of Drosophila and have produced hundreds of gene models using evidence-based manual annotation. Students appreciate their ability to make a contribution to ongoing research, and report increased independence and a more active learning approach after participation in GEP projects. They show knowledge gains on pre- and postcourse quizzes about genes and genomes and in bioinformatic analysis. Participating faculty also report professional gains, increased access to genomics-related technology, and an overall positive experience. We have found that using a genomics research project as the core of a laboratory course is rewarding for both faculty and students. PMID:20194808

    2010-01-01

    Controllers for scanning probe instruments can be programmed for automated lithography to generate desired surface arrangements of nanopatterns of organic thin films, such as n-alkanethiol self-assembled monolayers (SAMs). In this report, atomic force microscopy (AFM) methods of lithography known as nanoshaving and nanografting are used to write nanopatterns within organic thin films. Commercial instruments provide software to control the length, direction, speed, and applied force of the scanning motion of the tip. For nanoshaving, higher forces are applied to an AFM tip to selectively remove regions of the matrix monolayer, exposing bare areas of the gold substrate. Nanografting is accomplished by force-induced displacement of molecules of a matrix SAM, followed immediately by the surface self-assembly of n-alkanethiol molecules from solution. Advancements in AFM automation enable rapid protocols for nanolithography, which can be accomplished within the tight time restraints of undergraduate laboratories. Example experiments with scanning probe lithography (SPL) will be described in this report that were accomplished by undergraduate students during laboratory course activities and research internships in the chemistry department of Louisiana State University. Students were introduced to principles of surface analysis and gained “hands-on” experience with nanoscale chemistry. PMID:21483651

    McClure, Cynthia K.; Chenault, H. Keith

    1996-05-01

    A three-step laboratory sequence for the undergraduate organic laboratory is described. This series of experiments requires a student to use the product from one reaction as the starting material for a subsequent reaction, and thus the affords the student a "real world" experience of multistep synthesis. Thermal extrusion of sulfur dioxide from sulfolene is used to generate 1,3-butadiene in situ for a Diels-Alder cyclization with maleic anhydride. The anhydride is then reduced to the diol with lithium aluminum hydride. Oxidation of the diol to the chiral lactone is catalyzed by horse-liver alcohol dehydrogenase. This enzymatic oxidation illustrates in situ cofactor regeneration and allows students to measure simple enzyme kinetics.

    A well-constructed, step-by-step protocol is a critical starting point for teaching undergraduates new techniques, an important record of a lab's standard procedures, and a useful mechanism for sharing techniques between labs. Many research labs use websites to archive and share their protocols for these purposes. Here we describe our experiences developing and using a protocol website for the additional purpose of enhancing undergraduate research training. We created our lab's protocol website in a message board format that allows undergraduates to post comments on protocols describing the lessons they learned, questions that arose, and/or insights they gained while learning to execute specific research protocols. Encouraging and expecting students to comment on the protocols they are learning to execute is beneficial for both the student and for the lab in which they are training. For the student, annotations encourage active reflection on their execution of techniques and emphasize the important message that attending to and understanding details of a protocol is a critical factor in producing reliable data. For the lab, annotations capture valuable insights for future generations of researchers by describing missing details, hints, and common hurdles for newcomers. PMID:18765751

    A well-constructed, step-by-step protocol is a critical starting point for teaching undergraduates new techniques, an important record of a lab's standard procedures, and a useful mechanism for sharing techniques between labs. Many research labs use websites to archive and share their protocols for these purposes. Here we describe our experiences developing and using a protocol website for the additional purpose of enhancing undergraduate research training. We created our lab's protocol website in a message board format that allows undergraduates to post comments on protocols describing the lessons they learned, questions that arose, and/or insights they gained while learning to execute specific research protocols. Encouraging and expecting students to comment on the protocols they are learning to execute is beneficial for both the student and for the lab in which they are training. For the student, annotations encourage active reflection on their execution of techniques and emphasize the important message that attending to and understanding details of a protocol is a critical factor in producing reliable data. For the lab, annotations capture valuable insights for future generations of researchers by describing missing details, hints, and common hurdles for newcomers. PMID:18765751

  6. Hormones and Antibiotics in Nature: A Laboratory Module Designed to Broaden Undergraduate Perspectives on Typically Human-Centered Topics†

    Weber, Carolyn F.

    2014-01-01

    Bringing discovery-based research into undergraduate laboratory courses increases student motivation and learning gains over traditional exercises that merely teach technique or demonstrate well-documented phenomena. Laboratory experiences are further enhanced when they are designed to challenge student perspectives on topics relevant to their lives. To this end, a laboratory module on antibiotics and hormones, which are generally discussed in the context of human health, was developed for students to explore the multifaceted roles of antibiotics and hormones in nature (e.g. interspecies communication) via reading primary scientific literature and performing discovery-based experiments. The main objective of this module was to increase the general biological literacy of students as determined by their ability to connect the Five Core Concepts of Biological Literacy (American Association for the Advancement of Science, Vision and Change in Undergraduate Education: A Call to Action, 2011) to the topics “hormones” and “antibiotics” in pre- and postmodule surveys. After discussing unpublished research findings, cell biology students performed experiments demonstrating that: 1) fungi may promote fern growth via hormone production, 2) novel bacterial isolates in the genus Streptomyces produce antifungal compounds, and 3) subinhibitory antibiotic concentrations may enhance soil bacterial growth. The third finding provided evidence supporting a hypothesis framed in a scientific article that students read and discussed. Student perspectives on premodule surveys focused on roles of hormones and antibiotics in the human body (e.g. development, fighting infection), but their broadened postmodule perspectives encompassed the roles of these molecules in organismal communication and possibly the evolution of multicellularity.

    In this study, we investigated a pedagogical innovation in an undergraduate microbiology course, Microbes and Society, for non-microbiology majors and education majors. The aim was to improve students’ understanding by connecting their science experience to their areas of interest. Based on this idea of teaching, we redesigned the laboratory portion of a microbiology course. We had students in the laboratory component choose their areas of interest and use the areas as a framework for understanding science and how it influences and shapes the world around them. This course was part of a longitudinal project (Project Nexus) which prepares, supports, and sustains upper elementary and middle-level specialist science teachers. We used a battery of data collection instruments. We analyzed all data in several dimensions including using active-learning techniques, forming linkages between science and teaching, and connecting science and society. Our hypothesis was that we could promote science for all by connecting the diverse students’ areas of interest in science to the laboratory’s curriculum. We assessed the success of achieving our goal by using researchers’ observations, the instructors’ perspectives, and students’ feedback. Our findings suggested that this course was appreciated by the students, especially education majors, who recognized the innovations as engaging and worthwhile. PMID:23653691

    Measurement of energy distribution curves (EDCs) is one of the more powerful techniques for investigating the electronic band structure of solids. It would be profitable for undergraduate students to perform an experiment introducing them to this aspect of modern spectroscopy. In this paper we describe an arrangement we use in our course of modern physics for engineering students utilizing a commercial photocell. After a theoretical background on the photoemission process in metal, we present measurements on the EDCs obtained by graphical differentiation of the I-V characteristics of the photocell and by using an ac method where the differentiation is performed electronically.

    Objective : This study investigated the effect of completion of course prerequisites, undergraduate grade point average (GPA), undergraduate degree, and study habits on the performance of students in the biochemistry course at Palmer College of Chiropractic Florida. Methods : Students self-reported information regarding academic preparation at the beginning of the semester using a questionnaire. Final exam grade and final course grade were noted and used as measures of performance. Multivariate analysis of variance was used to determine if number of prerequisites completed, undergraduate GPA, undergraduate degree, hours spent studying in undergraduate study, and hours spent studying in the first quarter of the chiropractic program were associated significantly with the biochemistry final exam grade or the final grade for the biochemistry course. Results : The number of prerequisites completed, undergraduate degree, hours spent studying in undergraduate study, and hours spent studying in the first quarter of the chiropractic program did not significantly affect the biochemistry final exam grade or the final grade for the biochemistry course, but undergraduate GPA did. Subsequent univariate analysis and Tukey's post hoc comparisons revealed that students with an undergraduate GPA in the 3.5 to 3.99 range earned significantly higher final course grades than students with an undergraduate GPA in the 2.5 to 2.99 range. Conclusion : No single variable was determined to be a factor that determines student success in biochemistry. The interrelationship between the factors examined warrants further investigation to understand fully how to predict the success of a student in the biochemistry course. PMID:24295362

    1999-12-01

    The construction and use of an inexpensive photocatalytic reactor that utilizes titanium dioxide as the photocatalyst for wastewater treatment is described. In these experiments and in supplementary material, students are made aware that a variety of techniques have been developed to treat wastewaters, including those generated by the chemical industry. Water contaminated with the azo dye Congo Red was selected as an example of how one might treat contaminated water from a textile manufacturing facility. These experiments emphasize that, in addition to product development, chemists must also be concerned with waste treatment. A summary of the theory of titanium dioxide-mediated photocatalysis is provided. The phenomenon of photosensitization is also discussed. The usefulness of Congo Red is summarized and a brief history of this dye is given. In addition to being inexpensive, the photocatalytic reactor described is easy to construct and uses a readily available low-wattage fluorescent light. An important feature of this reactor is that the heat generated by the light source is readily dissipated by the water undergoing treatment. Thus no special cooling apparatus is required. One of the most important aspects of this work is that it provides a wide variety of continuing research suggestions that would be suitable and readily accomplished in undergraduate departments and high school laboratories; even those where budgetary priorities are a major concern. Use of this reactor would also enable students to design systems to treat "real-world" wastes, including some that are generated in instructional laboratories.

  6. The effectiveness and user perception of 3-dimensional digital human anatomy in an online undergraduate anatomy laboratory

    NASA Astrophysics Data System (ADS)

    Hilbelink, Amy Joanne

    2007-12-01

    The primary purpose of this study was to determine the effectiveness of implementing desktop 3-dimensional (3D) stereo images of human anatomy into an undergraduate human anatomy distance laboratory. User perceptions of 2D and 3D images were gathered via questionnaire in order to determine ease of use and level of satisfaction associated with the 3D software in the online learning environment. Mayer's (2001, p. 184) principles of design were used to develop the study materials that consisted of PowerPoint presentations and AVI files accessed via Blackboard. The research design employed a mixed-methods approach. Volunteers each were administered a demographic survey and were then stratified into groups based upon pre-test scores. A total sample size of 62 pairs was available for combined data analysis. Quantitative research questions regarding the effectiveness of 2D versus the 3D treatment were analyzed using a doubly-multivariate repeated measures (Doubly-MANOVA) design. Paired test scores achieved by undergraduates on a laboratory practical of identification and spatial relationships of the bones and features of a human skull were used in the analysis. The questionnaire designed to gather user perceptions consisted of quantitative and qualitative questions. Response frequencies were analyzed for the two groups and common themes were noted. Results revealed a statistically significant difference in group means for the main effect of the treatment groups 2D and 3D and for the variables of identification and relationship with the 3D group outperforming the 2D group on both dependent variables. Effect sizes were determined to be small, 0.215 for the identification variable and 0.359 for the relationship variable. Overall, all students liked the convenience of using PowerPoint and AVI files online. The 3D group felt their PowerPoint was more realistic than did the 2D group and both groups appreciated the detailed labeling of the online images. One third of the volunteers in the 3D group indicated that "eye strain" was what they liked least about working with the 3D images. Results indicate that desktop, stereo imaging may be incorporated effectively into online anatomy and physiology courses, but that more work needs to be done to ensure less eye strain.

    A suite of NASA-sponsored, Web-based exercises are in development for an introductory weather and climate course at Georgia State University (GSU) to improve climate literacy among undergraduate students. An extremely small percentage of the students are STEM majors. The exercises make extensive use of NASA resources and are guided in part by the concepts in Climate Literacy: The Essential Principles of Climate Science. At least two thousand undergraduate students have completed a majority of the exercises over the past two years. Nine of the twelve exercises in the course are connected strongly to climate literacy. The topics of those nine exercises are as follows: (1) Solar Irradiance, (2) Stratospheric Ozone, (3) Tropospheric Air, (4) The Carbon Cycle, (5) Global Surface Temperature, (6) Glacial-Interglacial Cycles, (7) Temperature Changes during the Past Millennium, (8) Climate & Ecosystems, and (9) Current & Future Climate Change. Two of the exercises (Tropospheric Air and The Carbon Cycle) make use of carbon dioxide (CO2) measurements made by students themselves and by a stationary CO2 monitor at GSU. The three remaining exercises, The Hadley Cell, Atlanta Weather, and Air Pollution, are less connected to multiple climate-literacy concepts; nonetheless, they provide a more complete experience for the students in the understanding of climate processes, differences between weather and climate, and human impacts on the atmosphere. All exercises are based on an inquiry-based learning cycle (i.e. 7 Es) and require substantial amounts of engagement, applied thinking, and critical thinking by the students. Not only do students become knowledgeable about the essential principles of climate change, especially global warming, but extensive use of geographical-information software and hand-held measurement devices has provided students with training in geography and technology. Student attitudes towards the labs were gathered via an on-line, anonymous survey from hundreds of students in Geography 1112 during the Fall semester of 2010. Students liked the use of high-quality imagery and animations, using Google™ earth, using Microsoft® Excel for calculations and chart production, going outside to collect data, and working in groups. Students did not like the large number of questions in some of the labs, not receiving a "lecture" in the beginning lab exercise, and improperly working Web links. Students suggested having a small lecture at the beginning in addition to having the topics be presented in the lecture sessions before doing the lab exercises as way to improve the labs. Therefore, students desired a more traditional approach to instruction. Seven lab instructors, all of whom were graduate students in the Department of Geosciences, were interviewed by the project evaluator in April of 2011. The main findings were as follows: the instructors viewed themselves as facilitators of the student-centered exercises; the students are uncomfortable with an inquiry-based approach; and there is disconnection between the lecture and lab portions of the course. Future work involves major pedagogical renovations to the exercises, training the lab instructors in the leading of inquiry-based exercises, and assessing student learning of climate-change concepts using pre- and post-tests.

    2006-01-01

    Complex biological structures, such as the human eye, have been interpreted as evidence for a creator for over three centuries. This raises the question of whether random mutation can create such adaptations. In this article, we present an inquiry-based laboratory experiment that explores this question using paper airplanes as a model organism. The main task for students in this investigation is to figure out how to simulate paper airplane evolution (including reproduction, inheritance, mutation, and selection). In addition, the lab requires students to practice analytic thinking and to carefully delineate the implications of their results. PMID:16951065

    Introduction: The aim of this survey study was to assess the current practices and policies in use related to the various steps in the blood gas testing process, across hospital laboratories in Croatia. Materials and methods: First questionnaire was sent by email to all medical biochemistry laboratories (N = 104) within general, specialized and clinical hospitals and university hospital centres to identify laboratories which perform blood gas analysis. Second questionnaire with detailed questions about sample collection, analysis and quality control procedures, was sent only to 47 laboratories identified by the first survey. Questionnaire was designed as combination of questions and statements with Likert scale. Third questionnaire was sent to all participating laboratories (N=47) for additional clarification for either indeterminate or unclear answers. Results: Blood gas analysis is performed in 47/104 hospital laboratories in Croatia. In 25/41 (0.61) of the laboratories capillary blood gas sampling is the preferred sample type for adult patient population, whereas arterial blood sample is preferentially used in only 5/44 laboratories (0.11). Blood sampling and sample processing for capillary samples is done almost always by laboratory technicians (36/41 and 37/44, respectively), whereas arterial blood sampling is almost always done by the physician (24/29) and only rarely by a nurse (5/28). Sample acceptance criteria and sample analysis are in accordance with international recommendations for majority of laboratories. 43/44 laboratories participate in the national EQA program. POCT analyzers are installed outside of the laboratory in 20/47 (0.43) institutions. Laboratory staff is responsible for education and training of ward personnel, quality control and instrument maintenance in only 12/22, 11/20 and 9/20 institutions, respectively. Conclusions: Practices related to collection and analysis for blood gases in Croatia are not standardised and vary substantially between laboratories. POCT analyzers are not under the direct supervision by laboratory personnel in a large proportion of surveyed institutions. Collective efforts should be made to harmonize and improve policies and procedures related to blood gas testing in Croatian laboratories. PMID:24969922

    Polarization measurements at X-ray and gamma-ray energies can provide crucial information on the emission region around massive compact objects such as black holes and neutron stars. The Polarized Gamma-ray Observer (PoGO) is a new balloon-borne instrument designed to measure polarization from such astrophysical objects in the 30-100 keV range, under development by an international collaboration with members from United States, Japan, Sweden and France. The PoGO instrument has been designed by the collaboration and several versions of prototype models have been built at SLAC. The purpose of this experiment is to test the latest prototype model with a radioactive gamma-ray source. For this, we have to polarize gamma-rays in a laboratory environment. Unpolarized gamma-rays from Am241 (59.5 keV) were Compton scattered at around 90 degrees for this purpose. Computer simulation of the scattering process in the setup predicts a 86% polarization. The polarized beam was then used to irradiate the prototype PoGO detector. The data taken in this experiment showed a clear polarization signal, with a measured azimuthal modulation factor of 0.35 {+-} 0.02. The measured modulation is in very close agreement with the value expected from a previous beam test study of a polarized gamma-ray beam at the Argonne National Laboratories Advanced Photon Source. This experiment has demonstrated that the PoGO instrument (or any other polarimeter in the energy range) can be tested in a libratory with a simple setup to a similar accuracy.

    The Desert Research Institute operates a high elevation facility, Storm Peak Laboratory (SPL), located on the Steamboat Springs Ski Resort at an elevation 10,500 ft. SPL provides an ideal location for long-term atmospheric research. The SPL mission statement is to ensure that the laboratory will continue to integrate climate research and education by advancing discovery and understanding within the field of pollution, aerosol and cloud interactions. During the last year, SPL has created two successful outreach programs reaching very different audiences. First, to engage students from local elementary schools, SPL established a 5th grade climate education program. This program is based on a partnership between SPL and Yampatika's&penvironmental educators. Yampatika is a non-profit outdoor environmental education organization. The program spans three days for each school and includes five elementary schools. During the first day, educators from Yampatika visit each classroom to introduce the concepts of climate and weather as well as teach students how to use scientific equipment. During the field program on the second day, students measure and record information about temperature, pressure, relative humidity, wind speed, and particle concentration while they travel to SPL via the gondola (in winter) or Suburban (in fall). Once at the laboratory, students tour the facility, discuss SPL research activities, and explore application of these activities to their curriculum. Following the field trip, Yampatika educators and SPL scientists will visit the school for a follow-up to help children explore concepts, answer questions, and evaluate students" learning. The second program, Geoscience Research at Storm Peak (GRASP), was designed to engage students from underrepresented groups and created a partnership between three Minority Serving Institutions and the University of Nevada, Reno (UNR). Undergraduate students from Tennessee State University, Howard University, Colorado State at Pueblo, and UNR will gather at SPL in the summer of 2008, via funding from the National Science Foundation. Throughout the year-long GRASP program, students encounter the scientific process - from creating a hypothesis, collecting and analyzing data, and presenting their results. Beginning in April, GRASP students will be presented with a short course in atmospheric science at their local institutions. The students will then begin formulating research questions for their time at SPL. In June, students will travel to SPL and work in small groups measuring cloud properties and trace gases with the guidance of an individual instructor. Data collected will be the basis for continuing student research projects. GRASP students and mentors will communicate regarding the progress of student research projects during the fall semester. All GRASP participants will meet at the campus of Howard University the following winter for a reunion workshop.

  5. Impact of a Backwards Faded Scaffolding (BFS) Approach to Inquiry-Based Astronomy Laboratory Experiences on Undergraduate Non-Science Majors' Views of Scientific Inquiry

    NASA Astrophysics Data System (ADS)

    Lyons, Daniel Jonathan

    2012-01-01

    In an effort to support effective instruction in undergraduate astronomy, the Center for Astronomy and Physics Education Research (CAPER) team introduced an inquiry-based laboratory curriculum designed using Backwards Faded Scaffolding (BFS) inquiry teaching framework. A major goal of the curriculum design was to enhance student learning beyond content knowledge alone toward more informed understandings of scientific inquiry through authentic astronomy inquiry experiences using astronomical data sets available online. This study explored the impact of that curriculum on undergraduate non-science majors’ views of the nature of scientific inquiry (NOSI). Over 200 introductory astronomy students’ were surveyed using the VOSI-4 questionnaire pre and post intervention. These data were analyzed for significant shifts in understanding of two aspects of NOSI; Distinction Between Data and Evidence (DvE) and Multiple Methods of Science (MMS). These results informed an investigation of lab instructors’ observations of students’ interactions with the intervention curriculum compared to traditional labs. Wilcoxon Signed Rank tests showed significant shifts in the distributions of Fall (n=112) and Spring (n=98) samples toward more informed understandings of DvE (Fall, z=-3.811, p<.00 Spring, z=-3.698, p<.001) , while there was no significant change for understanding of MMS (Fall, z=-.112, p=.910; Spring, z=-.607, p=.544). Instructor interview analysis suggested that the curriculum provided multiple opportunities for students to evaluate and determine the relevance of data with respect to specific research questions, however they may not have realized they were exclusively engaged in observational rather than experimental inquiries possibly leading students to accommodate their astronomy inquiry experiences within persistent misconceptions of "The Scientific Method” as the only valid method for inquiry. The results of the study suggest that a purposefully scaffolded, inquiry-based, introductory astronomy laboratory curriculum may be effective in enhancing undergraduate non-science majors’ understanding of scientific inquiry and may prove to be a valuable resource for undergraduate astronomy instructors.

    2001-01-01

    Over the last 20 years, biological MS has changed out of all recognition. This is primarily due to the development in the 1980s of 'soft ionization' methods that permit the ionization and vaporization of large, polar, and thermally labile biomolecules. These developments in ionization mode have driven the design and manufacture of smaller and cheaper mass analysers, making the mass spectrometer a routine instrument in the biochemistry laboratory today. In the present review the revolutionary 'soft ionization' methods will be discussed with particular reference to electrospray. The mass analysis of ions will be described, and the concept of tandem MS introduced. Where appropriate, examples of the application of MS in biochemistry will be provided. Although the present review will concentrate on the MS of peptides/proteins and lipids, all classes of biomolecules can be analysed, and much excellent work has been done in the fields of carbohydrate and nucleic acid biochemistry.

  7. Becoming a scientist: A qualitative study of the educational experience of undergraduates working in an American and a Brazilian research laboratory

    NASA Astrophysics Data System (ADS)

    Pascoa, Maria Beatriz Amorim

    Because the production of scientific and technological innovations has been at the center of debates for economic growth, scientists are recognized as important actors in the current global market. In this study, I will examine the undergraduate education of future scientists by focusing on students working in research projects of faculty members. This research activity has been promoted by American and Brazilian public agencies as an attempt to attract more college students to scientific careers as well as to improve their future performance in science. Evaluations of these programs have focused on important quantitative indicators focusing mainly on the amount of students that later choose to pursue scientific careers. However, these studies fail to address important educational aspects of undergraduates' experience. In this research, I explore the educational processes taking place as students are introduced to the making of science in order to understand how and what they are learning. Three bodies of literature illuminates the formulation and the analysis of the research questions: (1) theories of globalization situate the education of scientists within the dynamics of a broader social, economic, cultural, and historical framework; (2) the critical pedagogy of Paulo Freire is the basis for the understanding of the pedagogical processes shaping undergraduate students' experiences within the research site; (3) Critical and Cultural Studies of Science and Technology illuminate the analysis of the complex interactions and practices constructed within the laboratory. In order to understand the educational processes shaping the experiences of undergraduate students engaged in research activities, I conducted a qualitative investigation based on participant-observation and in-depth interviews in an American and a Brazilian laboratories. The two sites constituted insightful case studies that illuminated the understanding of inquires about the training of students in science. In addition, the study of two countries enriched the research inquiry, adding to the findings reflections on the ways differences in national contexts affects scientific training and scientific practices. Mainly, this qualitative research of students in laboratories offers some concrete recommendations and illuminating reflections for science educators, science policy makers, and for those working in the understanding of science epistemologies.

    Entrained mineral dust aerosol accounts for 45% of the global annual atmospheric aerosol load and can have a significant influence on important environmental issues, including climate, atmospheric chemistry, cloud formation, biogeochemical processes, visibility, and human health. 70% of all mineral aerosol mass originating from Africa consists of layered aluminosilicates, including illite, kaolinite, and montmorillonite clays. Clay minerals are a largely neglected component of mineral aerosol, yet they have unique physiochemical properties, including a high reactive surface area, large cation exchange capacities, small particle sizes, and a relatively large capacity to take up adsorbed water, resulting in expansion of clay layers (and a larger reactive surface area for heterogeneous interactions) in some cases. An integrated laboratory research approach has been implemented at Hendrix College, a Primarily Undergraduate Institution, in which undergraduate students are involved in independent and interdisciplinary research projects that relate the chemical aging processes (heterogeneous chemistry) of clay minerals as a major component of mineral aerosol to their effects on climate (water adsorption), atmospheric chemistry (trace gas uptake), and biogeochemistry (iron dissolution and phytoplankton biomarker studies). Preliminary results and future directions will be reported.

    Neuroimaging techniques, including positron emission tomography (PET), are widely used in clinical settings and in basic neuroscience research. Education in these methods and their applications may be incorporated into curricula to keep pace with this expanding field. Here, we have developed pedagogical materials on the fundamental principles of PET that incorporate a hands-on laboratory activity to view and analyze human brain scans. In this activity, students will use authentic PET brain scans generated from original research at Brookhaven National Laboratory (Volkow et al., 2009) to explore the neurobiological effects of a drug on the dopamine system. We provide lecture and assignment materials (including a 50-minute PowerPoint presentation introducing PET concepts), written background information for students and instructors, and explicit instructions for a 4-hour, computer-based laboratory to interested educators. Also, we discuss our experience implementing this exercise as part of an advanced undergraduate laboratory course at Stony Brook University in 2010 and 2011. Observing the living human brain is intriguing, and this laboratory is designed to illustrate how PET neuroimaging techniques are used to directly probe biological processes occurring in the living brain. Laboratory course modules on imaging techniques such as PET can pique the interest of students potentially interested in neuroscience careers, by exposing them to current research methods. This activity provides practical experience analyzing PET data using a graphical analysis method known as the Logan plot, and applies core neuropharmacology concepts. We hope that this manuscript inspires college instructors to incorporate education in PET neuroimaging into their courses. PMID:24693258

  5. Impact of backwards faded scaffolding approach to inquiry-based astronomy laboratory experiences on undergraduate non-science majors' views of scientific inquiry

    Lyons, Daniel J.

    This study explored the impact of a novel inquiry-based astronomy laboratory curriculum designed using the Backwards Faded Scaffolding inquiry teaching framework on non-science majoring undergraduate students' views of the nature of scientific inquiry (NOSI). The study focused on two aspects of NOSI: The Distinction between Data and Evidence (DvE), and The Multiple Methods of Science (MMS). Participants were 220 predominately non-science majoring undergraduate students at a small, doctoral granting, research-extensive university in the Rocky Mountain region of the United States. The student participants were enrolled in an introductory astronomy survey course with an associated laboratory section and were selected in two samples over consecutive fall and spring semesters. The participants also included four of the graduate student instructors who taught the laboratory courses using the intervention curriculum. In the first stage, student participant views of NOSI were measured using the VOSI-4 research instrument before and after the intervention curriculum was administered. The responses were quantified, and the distributions of pre and posttest scores of both samples were separately analyzed to determine if there was a significant improvement in understanding of either of the two aspects of NOSI. The results from both samples were compared to evaluate the consistency of the results. In the second stage, the quantitative results were used to strategically design a qualitative investigation, in which the four lab instructors were interviewed about their observations of how the student participants interacted with the intervention curriculum as compared to traditional lab activities, as well as their suggestions as to how the curriculum may or may not have contributed to the results of the first stage. These interviews were summarized and analyzed for common themes as to how the intervention curriculum influenced the students' understandings of the two aspect of NOSI. According to the results of a Wilcoxon Signed Rank test, there was a significant shift in the distributions of both samples toward a more informed understanding of DvE after the intervention curriculum was administered, while there was no significant change in either direction for understanding of MMS. The results of the instructor interview analysis suggested that the intervention curriculum provided multiple opportunities for students to evaluate and determine the relevance of data in the context of producing evidence-based conclusions directly related to specific research questions, thereby supporting the development of more informed views of DvE. These results also suggested that students might not have realized that they were exclusively engaged in non-experimental type inquiries, as various research methods were not explicitly addressed. The intervention curriculum used a consistently phased stepwise format, which may also have led the students to accommodate their astronomy inquiry experiences within persistent misconceptions of "The Scientific Method" as the only valid means of constructing scientific knowledge, thereby leading to no change in understanding of MMS. The results of the study suggest that a scaffolded, inquiry-based, introductory astronomy laboratory curriculum purposefully designed and scaffolded to enhance students' understandings could be effective in enhancing undergraduate non-science majoring students' views of certain aspects of NOSI. Through scaffolding inquiry experiences that deliver multiple opportunities to engage in authentic scientific inquiries, the novel curriculum provides a valuable resource for the astronomy education community to engage students in learning experiences that reflect the contemporary views of constructivist inquiry-based learning, which focuses on the interpretation of data to create evidence in light of specific questions, as well as opportunities to engage in authentic scientific discourse. As such it can enable astronomy educators in the undergraduate teaching community to support student

    Domestic oil production is declining and United States reliance on imported oil is increasing. America will be faced with difficult decisions that address the strategic, economic, and political consequences of its energy resources shortage. The geologically literate under-graduate student needs to be aware of current and future United States energy issues. The U.S. Geological Survey periodically provides energy assessment data via digitally-formatted CD-ROM publications. These publications are free to the public, and are well suited for use in undergraduate geology curricula. The U.S. Geological Survey (USGS) 1995 National Assessment of United States Oil and Gas Resources (Digital Data Series or DDS-30) (Gautier and others, 1996) is an excellent resource for introducing students to the strategies of hydrocarbon exploration and for developing skills in problem-solving and evaluating real data. This paper introduces the reader to DDS-30, summarizes the essential terminology and methodology of hydrocarbon assessment, and offers examples of exercises or questions that might be used in the introductory classroom. The USGS contact point for obtaining DDS-30 and other digital assessment volumes is also provided. Completing the sample exercises in this report requires a copy of DDS-30.

  9. Extending students' practice of metacognitive regulation strategies in the undergraduate chemistry laboratory and investigation of Pb2+ binding to calmodulin with circular dichroism and molecular dynamics modeling

    NASA Astrophysics Data System (ADS)

    Valencia Navarro, Laura N.

    The following dissertation was composed of two projects in chemistry education and benchwork/computational biochemistry. The chemistry education research explored students' practice of metacognitive strategies while solving open-ended laboratory problems when engaged in an instructional environment, the Science Writing Heuristic (SWH), that was characterized as supporting metacognitive regulation strategy use. Through in-depth interviews with students, results demonstrated that students in the SWH environment, compared to non-SWH students, used metacognitive strategies to a greater degree and to a greater depth when solving open-ended laboratory problems. As students engaged in higher levels of metacognitive regulation, their elective use of peers became a prominent path for supporting the practice of metacognitive strategies. Students claimed that the structure of the SWH weekly laboratory experiments improved their ability to solve open-ended lab problems. This research not only provided a lens into students' descriptions of their regulation strategy practices in the laboratory, but it also supported that the way that a laboratory environment is arranged can affect these regulation strategy practices and their transfer to new situations. In the biochemical study on the binding of Pb2+ to calmodulin (CaM), data was acquired via circular dichroism (CD) and molecular dynamics modeling. CD signal data indicated a unique signal from Pb-CaM and a significantly smaller ratio theta208/theta222 for Pb-CaM than Ca-CaM. An analysis of secondary structure content indicated that alpha-helical structure decreased and random coil structure increased when CaM was saturated with Pb2+ compared to Ca2+ saturated CaM. A molecular dynamics simulation of Pb2+ binding to CaM showed that Pb2+ ions bound to sites outside of the known canonical binding sites including the linker region, and indicated change in secondary structure. These results support the theory of opportunistic binding of Pb 2+ to CaM, and confirm previous research of binding sites in the linker region (Met 76 to Asp 84). The method of random ion (Pb2+ >) placement with a protein (CaM) in a water box provided an accurate prediction of binding sites, correctly predicting four of five binding sites found on both crystal structures of Pb-CaM.

  12. Biochemistry (by Jochanan Stenesh)

    NASA Astrophysics Data System (ADS)

    Glasfeld, Arthur

    1999-06-01

    Plenum: New York, 1998. Hardcover, ISBN 0 306-45732-6. 95. Paperback, ISBN 0 306 45733 4. 55 (set of 3). Solutions manual and transparencies available. According to the promotional materials accompanying this text, its intended audience is students in one-semester undergraduate biochemistry courses. At just over 500 pages, the book is shorter than the norm of well over 1000 pages. The challenge, then, is to present the subject in a coherent and compelling fashion while necessarily omitting a large fraction of the material that one normally finds in more inclusive texts. That kind of editing is obviously going to lead to squawking from some quarters, so I should put my prejudices on the table. I teach a one-semester course in biochemical structure, and I have a long-standing interest in using molecular models to explain biochemical behavior, both in research and in teaching. The editing performed by Professor Stenesh is likely to trouble someone with a structural or mechanistic background. Rather than selectively excluding some topics, Stenesh has created a table of contents that looks like it's from a much longer text. The usual chapters on biochemical structure, catalysis, metabolism and molecular genetics are included here. The ax fell elsewhere, and most obvious to my eye are the omissions of structure and chemical mechanism beyond those few chapters that are dedicated to them. A brief presentation on the structure and function of hemoglobin is given in the chapter on proteins, and the catalytic mechanism of chymotrypsin is briefly presented in the chapter on catalysis. But in chapters on metabolism, the structures of substrates and products are shown while mechanisms of conversion are omitted. For example, in the description of aldolase, we're informed that the enzyme catalyzes a reverse aldol condensation, but the reader isn't shown how the aldol condensation relates to the chemical conversion we see in the figure. (Part of the problem may be that the text assumes only one semester of preparation in organic chemistry, which might not be adequate for a discussion of biochemical mechanism.) In the section on gene regulation, no mention is made of the atomic-level interactions between regulatory proteins and DNA that lead to specific, high-affinity binding. The helix-turn-helix motif isn't even mentioned. Obviously, in a 500-page text, something had to go. It's too bad, though, that the omitted material includes the structural and mechanistic explanations for the chemical transformations and cellular processes being described. These complaints shouldn't overshadow the fact that this is a thoughtfully constructed text. The writing is both clear and simple. Broken into subsections, topics are presented in brief synopses that carefully identify key terms and ideas, and the problems at the back of the chapters are plentiful and appropriate. Stenesh's presentation is logically sound. I appreciated the presentation of thermodynamics in a chapter that directly precedes metabolism, rather than the more common brief review that appears in the earliest chapters. Likewise, the inclusion of enzyme catalysis directly after protein structure works in the context of this text. I noted a few small errors, but nothing that would cause distractions for the student. Unfortunately, the two-color graphics that accompany the text are less than compelling by current standards (also, a relatively greater number of errors appear in the figures). In drawing chemical structures, little effort is made to show molecular shape. For example, the figures use Fischer projections (without definition before Chapter 5) to define stereoisomers, and only in the appendix are dashes and wedges used to define them. This is particularly problematic in the chapter on amino acids, where their chirality is described but never illustrated. It is difficult to see the three-dimensional concepts being presented in the two-dimensional format being used. In topics where good visuals would be most useful (such as protein and DNA structure), the figures are reminiscent o

  20. A Western Blot-based Investigation of the Yeast Secretory Pathway Designed for an Intermediate-Level Undergraduate Cell Biology Laboratory

    PubMed Central

    2008-01-01

    The movement of newly synthesized proteins through the endomembrane system of eukaryotic cells, often referred to generally as the secretory pathway, is a topic covered in most intermediate-level undergraduate cell biology courses. An article previously published in this journal described a laboratory exercise in which yeast mutants defective in two distinct steps of protein secretion were differentiated using a genetic reporter designed specifically to identify defects in the first step of the pathway, the insertion of proteins into the endoplasmic reticulum (Vallen, 2002). We have developed two versions of a Western blotting assay that serves as a second way of distinguishing the two secretory mutants, which we pair with the genetic assay in a 3-wk laboratory module. A quiz administered before and after students participated in the lab activities revealed significant postlab gains in their understanding of the secretory pathway and experimental techniques used to study it. A second survey administered at the end of the lab module assessed student perceptions of the efficacy of the lab activities; the results of this survey indicated that the experiments were successful in meeting a set of educational goals defined by the instructor.

  1. Assessing student perspectives of the laboratory, self-efficacy in chemistry, and attitudes towards science in an undergraduate first-semester general chemistry laboratory

    NASA Astrophysics Data System (ADS)

    Olave, Marcella

    Research is lacking in the general chemistry laboratory that explores the concerted affective predictor variables of student perspectives of the laboratory, self-efficacy in chemistry, and student attitudes towards science. There is little research on the assessment of variables in the affective domain to determine student experiences in the chemistry laboratory. Student experiences in this study were assessed by determining congruence between student perspectives of their actual and preferred general chemistry laboratory environment using the SLEI, and student attitudes towards careers as a scientist using the SAI II. Correlations between scales from the SLEI, SAI II along with the CCSS that measures self-efficacy in college chemistry were identified. A sample of eighty college students enrolled in a first-semester general chemistry laboratory responded to the SLEI, SAI II, and CCSS. A t test indicated there were no significant differences with student cohesiveness, integration, material environment, and rule clarity between the actual and preferred SLEI signifying congruence. There were significant differences between students actual and preferred perception of open-endedness (t = -3.59, df = 28, p = 0.00). Student attitudes towards careers as a scientist could not be determined using pretests and posttests of the SAI II due to a ceiling effect. There were positive significant correlations found between the scales of material environment, integration from the SLEI and the scale of student attitudes towards careers as a scientist using the SAI II. There were also positive significant correlations between self-efficacy for everyday applications, and self-efficacy for cognitive skills from the CCSS with the scale of student attitudes towards careers as a scientist. This study is of significance since it is the first study exploring congruence between the actual and preferred student perspectives of the laboratory using the SLEI in a first semester general chemistry laboratory. It is also the first to report correlations between combined affective variables of student perspectives of the laboratory using the SLEI, student attitudes towards careers as a scientist with the SAI II, and self-efficacy in chemistry with the CCSS. Understanding student experiences through the assessment of these affective variables can help educators modify first-semester general chemistry laboratory activities to create a positive experience for students.

    1986-01-01

    The present studies have shown that GSH metabolism arose in the purple bacteria and cyanobacteria where it functions to protect against oxygen toxicity. Evidence was obtained indicating that GSH metabolism was incorporated into eucaryotes via the endosymbiosis giving rise to mitochrondria and chloroplasts. Aerobic bacteria lacking GSH utilize other thiols for apparently similar functions, the thiol being coenzyme A in Gram positive bacteria and chi-glutamylcysteine in the halobacteria. The thiol biochemistry of prokaryotes is thus seen to be much more highly diversified than that of eucaryotes and much remains to be learned about this subject.

  14. THE BIOCHEMISTRY OF ANTHOCYANINS.

    PubMed

    Bancroft, W D

    1943-07-30

    1. An explanation has been given for the effect of subdued light on the development of anthocyanins. This effect was observed by von Sachs and by Sorby seventy years ago. Nobody has made an exhaustive study of the subject, although Askenasy, Hugo Fischer and others have done work along these lines. 2. When a flavone is reduced to an anthocyanin, as with the Japanese quince, cutting off ultra-violet light prevents the formation of the anthocyanin. 3. When the anthocyanin is formed by the hydrolysis of a leuco-anthocyanin, cutting off of ultraviolet light will not necessarily prevent the formation of the anthocyanin. This occurs with the geranium. 4. We do not know at all approximately how many or which flowers belong to what I call the flavone type and how many or which to the leuco-anthocyanin type. 5. After the biochemistry of the anthocyanins shall have been worked out the botanists and chemists should concentrate on the biochemistry of the carotenes, the lycopenes and chlorophyll. PMID:17743749

  1. The effect of following learning style pathways on learning and satisfaction in online biology laboratories for non-science-major undergraduates

    NASA Astrophysics Data System (ADS)

    Ritschel-Trifilo, Patricia M.

    Learning is a biological process involving horizontal and vertical synapse formations in the brain resulting in established neuronal pathways. Each learner has a unique biological makeup resulting in individual approaches to acquire, understand, and perceive information, which constitutes their learning styles. Learners have a dominant and several subdominant learning styles they use to explore new material. This study investigates the effect of following learning style pathways on learning and satisfaction in an online biology laboratory for non-science-major undergraduates. Participants in the control group, without knowledge of learning styles, randomly chose from eight instructional strategies, to create a pathway to explore the subject of fermentation and enzymes. Each participant in the experimental group was tested to determine dominant and subdominant learning styles, and was then instructed to follow a specific pathway that conformed to his or her learning styles through the instructional materials to explore the topics. Results of the study show a statistically significant improvement in learning when instructional strategies are matched to dominant and subdominant learning styles compared to instructional strategies unmatched to learning styles. Learners following the learning style pathway exactly as suggested by Canfield Learning Styles Inventory, with the dominant instruction first, accomplished extremely significantly higher posttest scores over those who only partially followed the suggested learning path. Learners expressed a higher level of satisfaction with the instruction and greater ease of learning when the instructional strategies matched learning styles. Research results suggest that, if the instructional strategies incorporated into an online laboratory presenting unfamiliar material to learners do not match the learner's style, the learner is forced to use a brain pathway with little neuronal connectivity resulting in poor learning and understanding, and dissatisfaction with the instruction.

    PubMed Central

    Burke, John E.; Dennis, Edward A.

    2010-01-01

    The phospholipase A2 (PLA2) superfamily consists of many different groups of enzymes that catalyze the hydrolysis of the sn-2 ester bond in a variety of different phospholipids. The products of this reaction, a free fatty acid, and lysophospholipid have many different important physiological roles. There are five main types of PLA2: the secreted sPLA2’s, the cytosolic cPLA2’s, the Ca2+ independent iPLA2’s, the PAF acetylhydrolases, and the lysosomal PLA2’s. This review focuses on the superfamily of PLA2 enzymes, and then uses three specific examples of these enzymes to examine the differing biochemistry of the three main types of these enzymes. These three examples are the GIA cobra venom PLA2, the GIVA cytosolic cPLA2, and the GVIA Ca2+-independent iPLA2. PMID:18931897

  3. Using a PyMOL Activity to Reinforce the Connection between Genotype and Phenotype in an Undergraduate Genetics Laboratory

    2014-01-01

    With the purpose of developing an activity that would help clarify genetic concepts related to the connection between genotype and phenotype and the nature of mutations, we designed a three hour teaching module using the PyMol software. The activity starts with two pre-laboratory assignments, one to learn how to use PyMol and the other to read about a specific protein or protein family. During the laboratory students are given instructions where and how to find additional information on a specific disease and its causal mutations in order to prepare a 10-minute, in-class presentation. Using a post activity, anonymous quiz, we found a statistically significant different grade distribution in students that participated in the PyMol activity relative to a control group. We also found a significant improvement in the student’s comprehension when answering questions regarding the nature of mutations and protein structure. This demonstrates the utility of this simulation activity as a vehicle to improve student’s understanding of specific key genetic concepts. PMID:25461967

    2011-12-01

    As part of a 3-wk intersession workshop funded by a National Science Foundation Expeditions in Computing award, 15 undergraduate students from the City University of New York(1) collaborated on a study aimed at characterizing the voltage dynamics and arrhythmogenic behavior of cardiac cells for a broad range of physiologically relevant conditions using an in silico model. The primary goal of the workshop was to cultivate student interest in computational modeling and analysis of complex systems by introducing them through lectures and laboratory activities to current research in cardiac modeling and by engaging them in a hands-on research experience. The success of the workshop lay in the exposure of the students to active researchers and experts in their fields, the use of hands-on activities to communicate important concepts, active engagement of the students in research, and explanations of the significance of results as the students generated them. The workshop content addressed how spiral waves of electrical activity are initiated in the heart and how different parameter values affect the dynamics of these reentrant waves. Spiral waves are clinically associated with tachycardia, when the waves remain stable, and with fibrillation, when the waves exhibit breakup. All in silico experiments were conducted by simulating a mathematical model of cardiac cells on graphics processing units instead of the standard central processing units of desktop computers. This approach decreased the run time for each simulation to almost real time, thereby allowing the students to quickly analyze and characterize the simulated arrhythmias. Results from these simulations, as well as some of the background and methodology taught during the workshop, is presented in this article along with the programming code and the explanations of simulation results in an effort to allow other teachers and students to perform their own demonstrations, simulations, and studies.

  11. Nutritional Biochemistry of Space Flight

    NASA Technical Reports Server (NTRS)

    Smith, Scott M.

    2000-01-01

    Adequate nutrition is critical for maintenance of crew health during and after extended-duration space flight. The impact of weightlessness on human physiology is profound, with effects on many systems related to nutrition, including bone, muscle, hematology, fluid and electrolyte regulation. Additionally, we have much to learn regarding the impact of weightlessness on absorption, mtabolism , and excretion of nutrients, and this will ultimately determine the nutrient requirements for extended-duration space flight. Existing nutritional requirements for extended-duration space flight have been formulated based on limited flight research, and extrapolation from ground-based research. NASA's Nutritional Biochemistry Laboratory is charged with defining the nutritional requirements for space flight. This is accomplished through both operational and research projects. A nutritional status assessment program is included operationally for all International Space Station astronauts. This medical requirement includes biochemical and dietary assessments, and is completed before, during, and after the missions. This program will provide information about crew health and nutritional status, and will also provide assessments of countermeasure efficacy. Ongoing research projects include studies of calcium and bone metabolism, and iron absorption and metabolism. The calcium studies include measurements of endocrine regulation of calcium homeostasis, biochemical marker of bone metabolism, and tracer kinetic studies of calcium movement in the body. These calcium kinetic studies allow for estimation of intestinal absorption, urinary excretion, and perhaps most importantly - deposition and resorption of calcium from bone. The Calcium Kinetics experiment is currently being prepared for flight on the Space Shuttle in 2001, and potentially for subsequent Shuttle and International Space Station missions. The iron study is intended to assess whether iron absorption is down-regulated dUl1ng space flight. This is critical due to the red blood cell changes which occur, and the increase in iron storage that has been observed after space flight. The Iron Absorption and Metabolism experiment is currently planned for long-term flights on the International Space Station.

    2010-11-01

    This study examined the historical performance of students at Michigan State University in a two-part biochemistry series Biochem I (n = 5,900) and Biochem II (n = 5,214) for students enrolled from 1997 to 2009. Multiple linear regressions predicted 54.9-87.5% of the variance in student from Biochem I grade and 53.8-76.1% of the variance in student from Biochem II grade. Overall, the student's cumulative GPA has the primary influence on their biochemistry grade in Biochem I for all models whereas either cumulative GPA or Biochem I performance has the primary influence on Biochem II grade. These factors were far more influential than any other predictors as their ? values were larger (5-10 times larger depending on the model). However, the gender of the student was also statistically significant for Biochem I and more than half of our Biochem II models with female students always predicted lower than their equivalent male counterparts. Biochemistry majors were also found to perform better in Biochem I. Interestingly, grades earned in prerequisite courses such as introductory biology, chemistry, or organic chemistry and ethnicity provided no additional predictive ability about students' performance in biochemistry. Enrollment in an honors college or science residential college had little direct impact on performance in biochemistry. PMID:21567866

    Biochemical studies have complemented ultrastructural and, subsequently molecular genetic evidence consistent with the Charophyceae being the closest extant algal relatives of the embryophytes. Among the genes used in such molecular phylogenetic studies is that rbcL) for the large subunit of ribulose bisphosphate carboxylase-oxygenase (RUBISCO). The RUBISCO of the embryophytes is derived, via the Chlorophyta. from that of the cyanobacteria. This clade of the molecular phylogeny of RUBISCO shows a range of kinetic characteristics, especially of CO2 affinities and of CO2/O2 selectivities. The range of these kinetic values within the bryophytes is no greater than in the rest of the embryophytes; this has implications for the evolution of the embryophytes in the high atmospheric CO2 environment of the late Lower Palaeozoic. The differences in biochemistry between charophycean algae and embryophytes can to some extent be related functionally to the structure and physiology of embryophytes. Examples of components of embryophytes, which are qualitatively or quantitatively different from those of charophytes, are the water repellent/water resistant extracellular lipids, the rigid phenolic polymers functional in water-conducting elements and mechanical support in air, and in UV-B absorption, flavonoid phenolics involved in UV-B absorption and in interactions with other organisms, and the greater emphasis on low Mr organic acids. retained in the plant as free acids or salts, or secreted to the rhizosphere. The roles of these components are discussed in relation to the environmental conditions at the time of evolution of the terrestrial embryophytes. A significant point about embryophytes is the predominance of nitrogen-free extracellular structural material (a trait shared by most algae) and UV-B screening components, by contrast with analogous components in many other organisms. An important question, which has thus far been incompletely addressed, is the extent to which the absence from bryophytes of the biochemical pathways which produce components found only in tracheophytes is the result of evolutionary loss of these functions.

  11. Metabolism and biochemistry in hypogravity

    1991-01-01

    The headward shift of body fluid and increase in stress-related hormones that occur in hypogravity bring about a number of changes in metabolism and biochemistry of the human body. Such alterations may have important effects on health during flight and during a recovery period after return to earth. Body fluid and electrolytes are lost, and blood levels of several hormones that control metabolism are altered during space flight. Increased serum calcium may lead to an increased risk of renal stone formation during flight, and altered drug metabolism could influence the efficacy of therapeutic agents. Orthostatic intolerance and an increased risk of fracturing weakened bones are concerns at landing. It is important to understand biochemistry and metabolism in hypogravity so that clinically important developments can be anticipated and prevented or ameliorated.

  17. Common student misconceptions in exercise physiology and biochemistry

    2008-01-28

    The present study represents a preliminary investigationdesigned to identify common misconceptions in students' understanding of physiological and biochemical topics within the academic domain of sport and exercise sciences. A specifically designed misconception inventory (consisting of 10 multiple-choice questions) was administered to a cohort of level 1, 2, and 3 undergraduate students enrolled in physiology and biochemistry-related modules of the BSc Sport Science degree at the authors' institute. Of the 10 misconceptions proposed by the authors, 9 misconceptions were confirmed. Of these nine misconceptions, only one misconception appeared to have been alleviated by the current teaching strategy employed during the progression from level 1 to 3 study. The remaining eight misconceptions prevailed throughout the course of the degree program, suggesting that students enter and leave university with the same misconceptions in certain areas of exercise physiology and biochemistry. The possible origins of these misconceptions are discussed, as are potential teaching strategies to prevent and/or remediate them for future years.

  18. Clinical biochemistry of dihydrotestosterone.

    Marchetti, Paula M; Barth, Julian H

    2013-03-01

    Dihydrotestosterone (DHT) is the most potent natural androgen in humans. There has been an increasing interest in this androgen and its role in the development of primary and secondary sexual characteristics as well as its potential roles in diseases ranging from prostate and breast cancer to Alzheimer's disease. Despite the range of pathologies shown to involve DHT there is little evidence for measurement of serum DHT in the management of these diseases. In this review we describe the physiology of DHT production and action, summarize current concepts in the role of DHT in the pathogenesis of various disorders of sexual development, compare current methods for the measurement of DHT and conclude on the clinical utility of DHT measurement. The clinical indications for the measurement of DHT in serum are: investigation of 5? reductase deficiency in infants with ambiguous genitalia and palpable gonads; men with delayed puberty and/or undescended testes; and to confirm the presence of active testicular tissue. Investigation is aided by the use of human chorionic gonadotrophin stimulation. Due to paucity of published data on this procedure, it is important to follow guidelines prescribed by the laboratory performing the analysis to ensure accurate interpretation. PMID:23431485
