  10. Student Teachers' Approaches to Teaching Biological Evolution

    NASA Astrophysics Data System (ADS)

    Borgerding, Lisa A.; Klein, Vanessa A.; Ghosh, Rajlakshmi; Eibel, Albert

    2015-06-01

    Evolution is fundamental to biology and scientific literacy, but teaching high school evolution is often difficult. Evolution teachers face several challenges including limited content knowledge, personal conflicts with evolution, expectations of resistance, concerns about students' conflicts with religion, and curricular constraints. Evolution teaching can be particularly challenging for student teachers who are just beginning to gain pedagogical knowledge and pedagogical content knowledge related to evolution teaching and who seek approval from university supervisors and cooperating teachers. Science teacher educators need to know how to best support student teachers as they broach the sometimes daunting task of teaching evolution within student teaching placements. This multiple case study report documents how three student teachers approached evolution instruction and what influenced their approaches. Data sources included student teacher interviews, field note observations for 4-5 days of evolution instruction, and evolution instructional artifacts. Data were analyzed using grounded theory approaches to develop individual cases and a cross-case analysis. Seven influences (state exams and standards, cooperating teacher, ideas about teaching and learning, concerns about evolution controversy, personal commitment to evolution, knowledge and preparation for teaching evolution, and own evolution learning experiences) were identified and compared across cases. Implications for science teacher preparation and future research are provided.

  18. Professional equity as reported by biology teachers

    NASA Astrophysics Data System (ADS)

    Douglas, Claudia B.; Lakes Matyas, Marsha; Butler Kahle, Jane

    In 1982, the National Association of Biology Teachers surveyed its membership in order to assess the role and status of women in biology education. Items describing roles, salaries, assignments, professional activities, and sexual bias were included in the survey. This paper compares the responses of male and female biology educators, draws conclusions from the data, and suggests implications for the science education profession. Inequality in several professional areas was revealed. More women than men were single and reported no dependent children. Women exceeded men in both the lower and upper ends of the distribution of years of experience. However, the percentage of men exceeded that of women in most salary brackets beyond $20,000 and more men reported paid consulting opportunities. Men tended to teach at larger institutions and, at all academic levels, more men taught advanced classes. More men than women were involved with research activities. However, neither sex felt that the other one received preferential treatment in regard to salary and promotion. The majority of education administrators as well as science and biology faculties were male. However, the recent influx of women into science education positions may produce important changes. It is recommended that a comparative study be conducted in five years.

  20. A comparison of teacher and principal perception of an outstanding biology teacher

    NASA Astrophysics Data System (ADS)

    Searles, William E.; Ng, Raymond W. M.

    The purpose of this study was to ascertain the level of agreement or disagreement between principals and teachers when using established criteria to measure the effectiveness of a biology teacher. To obtain information regarding their perceptions of an outstanding biology teacher, twenty-two principals and forty-one biology teachers were chosen randomly from English-speaking high schools within a 50 km radius of metropolitan Montreal, Quebec, Canada. The measuring instrument was a modified version of Dieter's questionnaire that evolved from his doctoral study of the National Association of Biology Teachers-Outstanding Biology Teacher Award Program. The data collected from the two populations were tested using one-way ANOVA (analysis of variance) or by applying normal approximation. Results indicated that both the principals and teachers agree on the relative importance of most criteria, particularly those related to the teacher's classroom behavior and academic background in biology. From such results, it was possible to construct one stereotype of the outstanding biology teacher. A number of recommendations were made from the results of the study, which were directed to the (a) teachers and their professional organization, (b) principals and the school boards, (c) teacher training institutions, and (d) researchers in teacher evaluation.

  4. Biology content cognitive structure: From science student to science teacher

    NASA Astrophysics Data System (ADS)

    Hauslein, Patricia L.; Good, Ronald G.; Cummins, Catherine L.

    The F-Sort of Biology Concepts was used to assess understanding of the relationships among 37 biology concepts by five groups: Preservice secondary science teachers, in-service biology teachers with 1-3 years of teaching experience, in-service biology teachers with 5 or more years of experience, scientists in any biological science field, and college seniors majoring in biology. Data collected from the F-sort were analyzed using latent partition analysis and alpha factor analysis with additional interpretation from multidimensional scaling. The subjects were asked to think aloud as they performed the F-sort and each session was audiotaped for later analysis. These analyses indicated that the biology major and experienced secondary science teachers were separated from the scientists by a dimension based on a deep-versus-surface structure understanding of the concepts. A second axis shows that scientists are separated from other groups by a fluid-versus-fixed cognitive structure dimension. That is, both experienced teachers and scientists were found to have well-constructed and ordered cognitive structures, but scientists were much more likely to see an item having a place in two or more categories, whereas experienced teachers tended to focus on only one aspect of an item, and therefore understanding that it rightfully belonged in only one category. It appears that teachers restructure their science knowledge as they become more experienced. There is an apparent transition from poorly organized to highly organized cognitive structures for biology concepts when comparing preservice, novice, and experienced teachers, respectively. The transition does not seem to be one achieving a deeper understanding of the biology concepts or to a greater degree of integration of the concepts, but rather a transition from a fairly large, loosely organized pool of biology concepts to one which is highly structured but limited to the expectations of the established curriculum.

    NASA Astrophysics Data System (ADS)

    Großschedl, Jörg; Harms, Ute; Kleickmann, Thilo; Glowinski, Ingrid

    2015-04-01

    What learning opportunities in higher education promote the development of content knowledge (CK), pedagogical content knowledge (PCK), and pedagogical knowledge (PK)? In order to investigate this question, a cross-sectional study with a total of 274 German preservice biology teachers (21.5 % male, average age 22.8 years) was conducted in German universities. Preservice teachers were recruited via announcements in teacher education courses. The participation rate amounted to 45 %. Results indicate that CK, PCK, and PK are three unique and separable, but correlated domains of knowledge. Regression analyses show how particular learning opportunities are related to preservice biology teachers' CK, PCK, and PK. Both (a) the type of teacher education program and (b) the period of university studies are related to CK and PCK. Moreover, (c) additional subjects studied and (d) teaching experience seem relevant for PCK development. Conclusions for teacher education are drawn.

  13. Teachers' and students' reactions to the Revised Nuffield A-Level Physics Course (RNAP)

    NASA Astrophysics Data System (ADS)

    Sela, David

    1990-07-01

    A battery of questionnaires and interviews with teachers and students experienced in RNAP, produced statistical data on many aspects of the course that leads to some guidelines and suggestions for better use of the course design and materials. The patterns described in this article relate to the responses of almost 200 teachers and about 100 students who were teaching and studying RNAP course during school year 1987/8. Though many of them criticised some aspects of the course, generally they were very enthusiastic about it and most of the information they gave us was accurate and reliable. The A-level physics teachers can choose either a `traditional' course or RNAP. We found that most of them don't like to change from one course to another. In the few cases it was done, the reasons generally were like `changing of school', `decreasing number of A-level physics students' or similar reasons. Most of RNAP teachers were keen about the course, its objectives and the way it prepares the students toward higher education as physicists or in other areas. Though pointing out its weaknesses, when comparing it with a `traditional' course, they stress much upon its advantages. We found a tendency to favour the course for the able student than for the weak or the average one. There was more than a feeling among teachers that the less motivated student can better succeed in a `traditional' course. This feeling became even stronger along the interviews where some teachers pointed out the high proportion of the selective schools doing RNAP, which made it more difficult (according to their feeling) for the average student to get an A or B grade. In some of the teachers' opinions RNAP is less suitable for girls who prefer a more `straightforward' course. It is interesting to point out that more than 50% of the students found the course more difficult than they expected it to be. Only 5% found it to be easier than they had suggested. Another point to think about is that almost one

    BouJaoude, Saouma; Asghar, Anila; Wiles, Jason R.; Jaber, Lama; Sarieddine, Diana; Alters, Brian

    2011-05-01

    This study investigated three questions: (1) What are Lebanese secondary school (Grade 9-12) biology teachers' and university biology professors' positions regarding biological evolution?, (2) How do participants' religious affiliations relate to their positions about evolutionary science?, and (3) What are participants' positions regarding evolution education? Participants were 20 secondary school biology teachers and seven university biology professors. Seventy percent of the teachers and 60% of the professors were Muslim. Data came from semi-structured interviews with participants. Results showed that nine (Christian or Muslim Druze) teachers accepted the theory, five (four Muslim) rejected it because it contradicted religious beliefs, and three (Muslim) reinterpreted it because evolution did not include humans. Teachers who rejected or reinterpreted the evolutionary theory said that it should not be taught (three), evolution and creationism should be given equal time (two), or students should be allowed to take their own stand. Two professors indicated that they taught evolution explicitly and five said that they integrated it in other biology content. One Muslim professor said that she stressed 'the role of God in creation during instruction on evolution'. It seems that years of studying and teaching biology have not had a transformative effect on how a number of teachers and professors think about evolution.

  18. High School Biology Teachers' Views on Teaching Evolution: Implications for Science Teacher Educators

    NASA Astrophysics Data System (ADS)

    Hermann, Ronald S.

    2013-06-01

    In the US, there may be few scientific concepts that students maintain preconceived ideas about as strongly and passionately as they do with regard to evolution. At the confluence of a multitude of social, religious, political, and scientific factors lies the biology teacher. This phenomenological study provides insight into the salient aspects of teaching evolution as viewed by public high school biology teachers. Transcribed interviews were coded, and data were sorted resulting in key themes regarding teachers' views of evolution education. These themes are presented against the backdrop of extant literature on the teaching and learning of evolution. Suggestions for science teacher educators are presented such that we can modify teacher preparation programs to better prepare science teachers to meet the challenges of teaching evolution.

  19. Performance-based assessment of biology teachers: Promises and pitfalls

    NASA Astrophysics Data System (ADS)

    Collins, Angelo

    BioTAP, the biology component of the Teacher Assessment Project, explored three modes of performance-based teacher assessment: portfolios, simulations, and portfolio-based simulations. Assessments were designed by a team of university-based researchers and classroom teachers. Assessments were completed by 15 high school biology teachers from a variety of teaching contexts. Portfolios are defined as collections of evidence gathered on site, such as videotapes of instruction. The portfolios had four sections: planning, instruction, assessment, and professional development. Simulation exercises are replications of critical tasks of teaching in a standardized setting, for example, an interview about adapting a textbook. Portfolio-based simulations take advantage of the contextual aspects of portfolios and the standardization of simulations, for example, an interview on student misconceptions about the laboratory experience that was presented in the portfolio. Using a holistic process, teachers were rated in categories derived from the five core propositions of teacher knowledge and skill proposed by the National Board for Professional Teaching Standards. Teachers reported that the assessments had a high degree of fidelity to teaching and provided stimuli to improving teaching. The description presented in this article provides a foundation for those who wish to advance the research in science teacher assessment.

  20. Connecting biology and mathematics: first prepare the teachers.

    PubMed

    Sorgo, Andrej

    2010-01-01

    Developing the connection between biology and mathematics is one of the most important ways to shift the paradigms of both established science disciplines. However, adding some mathematic content to biology or biology content to mathematics is not enough but must be accompanied by development of suitable pedagogical models. I propose a model of pedagogical mathematical biological content knowledge as a feasible starting point for connecting biology and mathematics in schools and universities. The process of connecting these disciplines should start as early as possible in the educational process, in order to produce prepared minds that will be able to combine both disciplines at graduate and postgraduate levels of study. Because teachers are a crucial factor in introducing innovations in education, the first step toward such a goal should be the education of prospective and practicing elementary and secondary school teachers.

    This paper reports a study of the alternative conceptions held by junior secondary science teachers enrolled in an in-service teacher training program. The subjects completed a written instrument which probed their understanding of biological concepts in the integrated science curriculum. The subjects, particularly the nonbiology graduates, were found to show serious misunderstanding in concepts concerning diversity of life, photosynthesis and respiration, reproduction, and detecting the environment. This finding supports the assertion that our science teachers, being graduates in specific areas, are inadequately prepared to teach a broad and balanced junior science curriculum. To strengthen the subject matter knowledge and pedagogical skills of prospective and practicing junior science teachers, a number of provisions are suggested for teacher training programs, undergraduate science courses, and school-based activities.

  11. A case study of two exemplary biology teachers

    Treagust, David F.

    Research has indicated that most science classrooms are not intellectually demanding and place little emphasis on small group discussions and laboratory activities. However, successful science programs and competent science teaching that can provide models for other science teachers do exist. This study sought to document the teaching practices of two exemplary biology teachers of grades 11 and 12 by means of an interpretive research methodology. Both teachers had a thorough and comprehensive knowledge of the content they were to teach and had a range of teaching strategies that could be used without a great deal of thought. Their expectations for student performance were high, consistent, and firm. Students were expected to complete a high level of academic work in discussions, in problem work, and in laboratory activities, and were encouraged to take responsibility for their own learning. A distinctive feature of these biology classes was the high level of managerial efficiency, where lessons were busy occasions for both teacher and students; students had little opportunity for off-task behavior. Both teachers actively monitored the behavior of both high- and low-ability students by moving around the room and speaking with individuals, while still maintaining control of the entire class. By manipulating questioning and the social environment, both teachers encouraged students to engage in work, gave effective praise to the whole class and to individuals, encouraged student input by referring to it, helped students to effectively use their time, and gave marks for completion of set work. Compared to research with less-successful teachers, these teaching behaviors contributed to exemplary practice.

    In order to understand how prospective teachers develop knowledge for teaching, researchers must identify the types of knowledge that are integral to effective science teaching. This case study investigated how 4 prospective secondary biology teachers' science teaching orientations, knowledge of science learners, and knowledge of instructional sequence, developed during a post-baccalaureate teacher education program. Data sources included a lesson planning task and two interview-observation cycles during the participants' year-long internship. Over the course of a year, the participants' science teaching orientations were based primarily on their K-16 learning experiences, and were robust and highly resistant to change. The prospective teachers became more aware of student learning difficulties, and therefore, developed more elaborated knowledge of the requirements of learning. They consistently sequenced instruction in ways that gave priority to transmitting information to students. Prospective teachers' development of knowledge of student understanding of science and instructional sequence were congruent with their science teaching orientations. Implications are given for teacher education and future research.

  16. Reform in biology education: Teachers' implementation of a new biology curriculum

    NASA Astrophysics Data System (ADS)

    Hasse, Eleanor Enthoven

    Biology: A Community Context (BACC) (Leonard & Penick, 1998) is a National Science Foundation funded high school biology curriculum designed to meet the goals of the reform movement in science education as envisioned in the National Science Education Standards (National Research Council, 1996) and the Benchmarks for Science Literacy (American Association for the Advancement of Science (AAAS), 1993). This study of a pilot implementation of the BACC curriculum illustrates some of the issues that emerged for teachers as they used an inquiry curriculum in the context of a district emphasis on meeting standards. In the first paper, "Teaching Biology Content Using an Inquiry Curriculum," I discuss the issues involved with teaching biology content using this inquiry curriculum. Teachers had difficulty bridging the gaps they perceived between the content in the curriculum and the content in their district standards; they had difficulty using the inquiry activities in the curriculum to teach content, and they did not accept some aspects of the instructional strategy. Professional development for teachers implementing inquiry curricula in the context of accountability for content oriented standards needs to address these issues directly and in an on-going fashion. In the second paper, "Is Science Education Reform Reaching the Classroom?", I use a framework developed by the National Research Council (2002) to investigate the ways in which these teachers and their classroom practices were affected by national standards. This framework has three channels of influence: ways in which national standards might affect classroom practice and thus student learning. These are curriculum, teacher development, and assessment and accountability practices. In the pilot implementation of BACC, all three channels had been influenced by "Standards" based reform, but they were not internally aligned nor were they completely coordinated with one another. This led to implementation issues

  13. Professional development strategies for teaching urban biology teachers to use concept maps effectively

    NASA Astrophysics Data System (ADS)

    McGregor Petgrave, Dahlia M.

    Many teachers are not adequately prepared to help urban students who have trouble understanding conceptual ideas in biology because these students have little connection to the natural world. This study explored potential professional development strategies to help urban biology teachers use concept maps effectively with various topics in the biology curriculum. A grounded theory approach was used to develop a substantive professional development model for urban biology teachers. Qualitative data were collected through 16 semi-structured interviews of professional developers experienced in working with concept maps in the urban context. An anonymous online survey was used to collect quantitative data from 56 professional developers and teachers to support the qualitative data. The participants were from New York City, recruited through the NY Biology-Chemistry Professional Development Mentor Network and the NY Biology Teachers' Association. According to the participants, map construction, classroom applications, lesson planning, action research, follow-up workshops, and the creation of learning communities are the most effective professional development strategies. The interviewees also proposed English language learning strategies such as picture maps, native word maps, and content reading materials with underlined words. This study contributes to social change by providing a professional development model to use in planning workshops for urban teachers. Urban teachers improve their own conceptual understanding of biology while learning how to implement concept mapping strategies in the classroom. Students whose teachers are better prepared to teach biology in a conceptual manner have the potential of growing into more scientifically literate citizens.

    NASA Astrophysics Data System (ADS)

    Mthethwa-Kunene, Eunice; Oke Onwu, Gilbert; de Villiers, Rian

    2015-05-01

    This study explored the pedagogical content knowledge (PCK) and its development of four experienced biology teachers in the context of teaching school genetics. PCK was defined in terms of teacher content knowledge, pedagogical knowledge and knowledge of students' preconceptions and learning difficulties. Data sources of teacher knowledge base included teacher-constructed concept maps, pre- and post-lesson teacher interviews, video-recorded genetics lessons, post-lesson teacher questionnaire and document analysis of teacher's reflective journals and students' work samples. The results showed that the teachers' individual PCK profiles consisted predominantly of declarative and procedural content knowledge in teaching basic genetics concepts. Conditional knowledge, which is a type of meta-knowledge for blending together declarative and procedural knowledge, was also demonstrated by some teachers. Furthermore, the teachers used topic-specific instructional strategies such as context-based teaching, illustrations, peer teaching, and analogies in diverse forms but failed to use physical models and individual or group student experimental activities to assist students' internalization of the concepts. The finding that all four teachers lacked knowledge of students' genetics-related preconceptions was equally significant. Formal university education, school context, journal reflection and professional development programmes were considered as contributing to the teachers' continuing PCK development. Implications of the findings for biology teacher education are briefly discussed.

  2. Student Perceptions of Their Biology Teacher's Interpersonal Teaching Behaviors and Student Achievement

    NASA Astrophysics Data System (ADS)

    Madike, Victor N.

    Inadequate student-teacher interactions in undergraduate courses have been linked to poor student performance. Researchers have noted that students' perceptions of student-teacher relationships may be an important factor related to student performance. The administration of a Mid-Atlantic community college prioritized increasing undergraduate biology student performance. The purpose of this quantitative study was to examine the relationship between students' biology achievement and their perceptions of interpersonal teaching behaviors and student-teacher interactions in introductory biology courses. Leary's theory on interpersonal communication and the systems communication theory of Watzlawick, Beavin, and Jackson served as the theoretical foundation. The Wubbel's Likert-scale questionnaire on student-teacher interactions was administered to 318 undergraduate biology students. Non-parametric Spearman's rank correlations revealed a significant direct correlation between students' grades and their perceptions of teachers' interpersonal teaching behaviors. The relationship between student achievement and students' perceptions of student-teacher interactions prompted the recommendation for additional study on the importance of student-teacher interactions in undergraduate programs. A recommendation for local practice included faculty development on strategies for improving student-teacher interactions. The study's implications for positive social change include increased understanding for administrators and instructors on the importance of teacher-student interactions at the community college level.

    Howarth, Richard T.

    Darwin's theory of evolution by natural selection is considered to be the unifying theory for all life sciences (American Association for the Advancement of Science, AAAS, 1990; National Academy of Sciences, 1998; National Research Council, NRC, 1996; National Science Teachers Association, NSTA, 2010a) and as such, the biology topic has been established as a central learning standard by the National Science Education Science Standards (NSES, 2005). The purpose of this study was to compare how Massachusetts and Texas high school biology teachers' attitudes toward the teaching of evolution differ as compared to other biology topics. Texas and Massachusetts are two states that exemplify standards based education yet differ dramatically in their histories surrounding the topic of evolution. A survey was conducted among 217 Massachusetts and 139 Texas in-service high school biology teachers to help provide a sense of the phenomena surrounding biology teachers in respect to how their attitudes towards the teaching of evolution are shaped. Additionally, an open-ended question was asked to help contextualize the results of the survey between teachers of these two states. The findings in this study suggest that community appears to be a powerful persuasive message and socialization experience that shapes the development of attitudes towards evolution for some educators, especially when it is highly intertwined with religion. For biology teachers in the state of Texas, the synergistic result of this relationship has resulted in statistically significant differences in regards to attitudes towards evolution as compared to teachers in Massachusetts. These findings yield implications regarding scientific literacy, student learning, assessment, the quality of science instruction, curriculum, undergraduate biology programs, and the needs of biology teachers in terms of professional development.

  6. Teachers' perceptions of the effects of a scientific literary course on subsequent learning in biology

    NASA Astrophysics Data System (ADS)

    Baker, Dale R.; Piburn, Michael D.; Piburn, Michael D.

    Five teachers were interviewed as to their perceptions of the effect of an intervention to teach scientific literacy on learning in subsequent biology courses. The sample consisted of 450 students who had a literacy course in ninth grade and had completed tenth-grade biology. At the end of the academic year the biology teachers were interviewed and asked to compare the biology students who had the literacy course to students they had taught in earlier years. The biology teachers concluded that the literacy course did have an effect on students' subsequent ability to learn biology. The strength of the effect varied according to level of biology. Students had a better understanding of the nature of science and better laboratory and process skills. They were also better at analyzing data. The advanced and intermediate biology students were more creative, more likely to take risks, and engage in hypothetical thinking than other groups of students that the teachers had taught. Although the purpose of the literacy course was to teach literacy skills the advanced students retained a substantial amount of content material that was applicable to biology.

  7. High school teachers' perspectives on effective approaches for teaching biology to students with special needs

    Kos, Agnieszka

    The demands of national educational reforms require high school biology teachers to provide high quality instruction to students with and without special needs. The reforms, however, do not provide teachers with adequate teaching strategies to meet the needs of all students in the same context. The purpose of this grounded theory study was to understand high school biology teachers' perspectives, practices, and challenges in relation to teaching students with special needs. This approach was used to develop a substantive model for high school biology teachers who are challenged with teaching students with and without special needs. Data were collected via in-depth interviews with 15 high school teachers in a Midwestern school district. The data were analyzed using open coding, axial coding, and selective coding procedures in accordance with the grounded theory approach. Essential model components included skills and training for teachers, classroom management strategies, teaching strategies, and student skills. The emergent substantive theory indicated that that teacher preparation and acquired skills greatly influence the effectiveness of inclusion implementation. Key findings also indicated the importance of using of a variety of instructional strategies and classroom management strategies that address students' special needs and their learning styles. This study contributes to social change by providing a model for teaching students and effectively implementing inclusion in regular science classrooms. Following further study, this model may be used to support teacher professional development and improve teaching practices that in turn may improve science literacy supported by the national educational reforms.

  12. Special and General Education Biology Teachers Working Together Collaboratively

    NASA Astrophysics Data System (ADS)

    Gagne-Grosso, Melissa

    Collaborative teaching, between special education and general education teachers working together, came about as a result of the No Child Left Behind and Individuals with Disabilities Education Acts. Despite the positive intentions of those acts, teachers are not always ready to teach collaboratively. Guided by the theories of fundamental change and inclusion, this study was based on a lack of understanding about collaborative teaching at 3 high schools. The research questions focused on the benefits, process, and concerns related to collaborative teaching. The perspectives of 4 special education and 8 regular education teachers in 3 urban, public high schools were collected through interviews and observations. Data were analyzed descriptively and inductively using coding, reconstruction, and interpretation of the underlying meanings. The findings revealed that teachers benefitted from being in these classrooms by having a reduced work load and shared responsibility; however, they needed more time for collaboration and modifying instruction, professional development, and stronger support. Students in these classrooms benefitted from social interactions with other students and by getting direct answers to questions. Based on these findings, a professional development training was created based on how collaborative teachers can work together to promote successful learning. This project study can have a positive impact by assisting collaborative teachers with support, communication, strategies for modifications and accommodations, and an enhanced experience, and additionally by improving the academic outcomes for their students.

    Lazarowitz, Reuven; Bloch, Ilit

    2005-12-01

    The purpose of this study was to investigate how aware high school biology teachers are of societal issues (values, moral, ethic, and legal issues) while teaching genetics, genetics engineering, molecular genetics, human heredity, and evolution. The study includes a short historical review of World War II atrocities during the Holocaust when scientists from all the above-mentioned disciplines had been involved in trying to support and develop the eugenics theories. It investigates pre- and postwar theories of the eugenics movement in the United States which were implemented successfully in Germany and a literature survey of the studies of societal issues related to these subjects. The sample consisted of 30 male and female biology teachers. Enclosed are teachers' answers in favor or against including debates about societal issues in their classrooms while teaching the disciplines mentioned above. Teachers' answers were analyzed in relation to three variables: years of teaching experience, gender, and religion faith. Data were collected from questionnaires and personal interviews and analyzed according to qualitative and quantitative methods. The results show that amongst the teachers there is a medium to low level of awareness of societal issues, while mainly emphasizing scientific subjects in preparation of matriculation examinations. The majority of the teachers do not include societal issues in their teaching, but if students raise these issues, teachers claimed to address them. No differences in teachers' opinions to societal issues were found in relation to gender or religious faith. Teachers with more years of teaching experience tend to teach with a more Science, Technology, and Society (STS) approach than novice teachers. The results are discussed in relation to teachers' professional development and teaching strategies are suggested to be used in their classrooms based on a STS approach, which includes the societal issues as a main goal.

  17. Factors which influence Texas biology teachers' decisions to emphasize fundamental concepts of evolution

    NASA Astrophysics Data System (ADS)

    Bilica, Kimberly Lynn

    The teaching of biological evolution in public science classrooms has been mitigated by a lingering and historic climate of controversy (Skoog, 1984; Skoog, 1979). This controversy has successfully stalled attempts to bring authentic science literacy to the American public (Bybee, 1997). The first encouraging signs of the abatement of this controversy occurred during the early 1990s when several prominent science organizations promoted evolution to its appropriate status as a central and unifying concept in biology (National Science Teachers Association, 1992; National Research Council, 1996; American Association for the Advancement of Science, 1990, 1993). The organizations acknowledged that not only should biological evolution be taught, evolution should stand as one of a select group of essential concepts upon which biology curricula should be built. Bandura's Social Learning theory (Bandura, 1997; Lumpe, Haney, & Czerniak, 2000) and Helms' Model of Identity (Helms, 1998) provide the theoretical basis for this study. Both Bandura and Helms explain the actions of teachers by examining the beliefs and values that influence their decisions. The models distinguish between two types of belief systems: capacity beliefs and context beliefs (Lumpe, et al, 2000; Helms, 1998). Both belief types influence and are influenced by individual actions. In this study, the action to be described is the decision that teachers make about the degree of emphasis on evolution in the classroom. The capacity beliefs that will be examined are teachers' beliefs about their capability to teach evolution. The contextual beliefs in this study are perceptions about students' capabilities to learn evolution, the status of evolution in science, the place of evolution in the biology classroom, the influence of textbooks, time, and community/school values. This study contributes to and extends the knowledge base established by studies of evolution education by exploring the relative amount of

  20. Expansion of Biology Teachers' Pedagogical Content Knowledge (PCK) During a Long-Term Professional Development Program

    NASA Astrophysics Data System (ADS)

    Rozenszajn, Ronit; Yarden, Anat

    2014-02-01

    Experienced teachers possess a unique teaching knowledge comprised of an inter-related set of knowledge and beliefs that gives direction and justification to a teacher's actions. This study examined the expansion of two components of pedagogical content knowledge (PCK) of three in-service teachers in the course of a professional development program aimed at designing new teaching and learning materials suggested by the teachers themselves. The research presents an enlargement of previous PCK representations by focusing on a detailed representation of two main PCK domains: teaching and learning, including ten PCK components that emerged in the course of data analysis. This representation enabled revealing the unique PCK held by each teacher and to characterize the expansion of the two components of the participating teachers' PCK during the long-term professional development program. Retention of major parts of the expanded PCK a year after termination of the program implies that designing and implementing new teaching and learning materials based on the teachers' experiences, needs, and knowledge in a workshop format accompanied by biology and science education courses might provide a powerful means for PCK expansion. We recommend that designers of professional development programs be aware of the unique PCK held by each teacher in order to promote meaningful professional development of each teacher. Moreover, the PCK representations that were identified in the course of this study enabled clarifying the "orientation toward teaching science" category of PCK which appears to be unclear in current literature.

  1. Developing Biology Lessons Aimed at Teaching for Understanding: A Domain-specific Heuristic for Student Teachers

    Janssen, Fred J. J. M.; Tigelaar, Dineke E. H.; Verloop, Nico

    2009-02-01

    Teaching for understanding requires teachers to organize thought-demanding activities which continually challenge students to apply and extend their prior knowledge. Research shows that student teachers often are unable to develop lessons in teaching for understanding. We explored how a domain-specific heuristic can assist student biology teachers in developing problem-posing lessons according to teaching for understanding. Worksheets of lesson plans were analyzed according to criteria for problem-posing lessons. Furthermore, student teachers’ perceptions of the design heuristic’s usefulness were categorized in a cyclical process. In general, the heuristic appeared helpful to most student teachers for designing problem-posing lessons satisfactory according to the criteria. Furthermore, teachers indicated that using the heuristic deepened their subject matter knowledge and their awareness of pupils’ prior knowledge.

  2. ComPratica: A Virtual Community of Practice for Promoting Biology Teachers' Professional Development in Brazil

    2013-08-01

    Teachers' professional development is a key factor in improving science education, but it shows limited impact when only a small number of teachers is reached, or when it focuses on only one aspect of teachers' development, such as learning science content, and is disconnected from teachers' practice. In order to increase the impact of our work on teachers' professional development, we implemented in 2007 ComPratica, an online network intended to establish a virtual community of practice involving biology teachers and biological education researchers. We present here the results of the first 2 years of this project, obtained through an analysis of the number and distribution of actions performed by the participants in the community, the kinds of activities in which they are engaged, and the themes addressed in their messages. From these data, we conclude that ComPratica is effectively functioning as a community of practice and is leading to changes related to both teachers' and researchers' professional development, which seem capable of reducing the research-practice gap in science education.

  3. Use of the "Tree" Analogy in Evolution Teaching by Biology Teachers

    NASA Astrophysics Data System (ADS)

    Marcelos, Maria Fátima; Nagem, Ronaldo Luiz

    2012-04-01

    This work discusses the use of Darwin's `Tree of Life' as a didactic analogy and metaphor in teaching evolution. It investigates whether biology teachers of pupils from 17 to 18 years old know Darwin's text `Tree of Life'. In addition, it examines whether those teachers systematically employ either the analogies present in that text or other analogies between the tree and evolution, and whether they adopt a specific methodology for teaching with analogies and metaphors (A&M). The academic training of teachers regarding use of A&M is review briefly. A diagnostic study was carried out with biology teachers in a public school in the town of Contagem in the state of Minas Gerais in Brazil. The data were obtained through direct observation, questionnaires and a focus group. The teachers pointed out in the questionnaires that some details of Darwin's analogy are utilized as a resource. However, analysis of the data indicates that the `Tree of Life' text is not known or utilized in class. At the same time, the teachers state that they use aspects of the tree as a didactic resource to teach evolution and that its use facilitates the learning of content. The teachers have little knowledge of specific methodologies of teaching with analogies and metaphors, revealing that their training is incomplete in this area.

  5. Three Southern high school biology teachers' perspectives on teaching evolution: Sociocultural influences

    NASA Astrophysics Data System (ADS)

    Kyzer, Peggy Mckewen

    Organizations in science and science education call for students to have a thorough understanding of the theory of evolution. Yet many high school biology teachers do not teach evolution and/or include creationism in their instruction (National Academy of Science, 1998). Historically, the controversy surrounding evolution has created tension for teachers. This case study explored the sociocultural influences related to teaching evolution in three Southern 10th-grade public high school biology classrooms. It also explored the socially and culturally embedded influences on teachers' instructional goals and personal perspectives toward evolution as well as modification of instruction when evolution is taught. Theoretically framed using symbolic interactionism and sociocultural theory, data were collected between October 2003 and April 2004 and included classroom observations two to three times per week, artifacts, and in-depth interviews of the participating teachers, their science department chairpersons, their students, and a Protestant minister. The classroom teachers were unaware of the focus of the study until after evolution was taught. The analysis used in this study was an inductive, interpretative approach that allowed exploration of the sociocultural influences that affect how teachers teach evolution. The sociocultural influences and the lived experiences of each teacher created a continuum for teaching evolution. One of the participating teachers who was heavily involved in the community and one of its fundamentalist churches elected to avoid teaching evolution. Another participating teacher at the same school integrated the theory of evolution in every unit. The third teacher who taught in another school elected to teach evolution in a superficial manner to avoid conflict. The data revealed that the participating teachers' sociocultural situatedness influenced their decisions and instruction on evolution. The influence of strong religious beliefs within

  6. Subject-specific pedagogical content knowledge: Implications for alternatively and traditionally trained biology teachers

    NASA Astrophysics Data System (ADS)

    Ravgiala, Rebekah Rae

    Theories regarding the development of expertise hold implications for alternative and traditional certification programs and the teachers they train. The literature suggests that when compared to experts in the field of teaching, the behaviors of novices differ in ways that are directly attributed to their pedagogical content knowledge. However, few studies have examined how first and second year biology teachers entering the profession from traditional and alternative training differ in their demonstration of subject-specific pedagogical content knowledge. The research problem in this multicase, naturalistic inquiry investigated how subject-specific pedagogical content knowledge was manifested among first and second year biology teachers in the task of transforming subject matter into forms that are potentially meaningful to students when explicit formal training has been and has not been imparted to them as preservice teachers. Two first year and two second year biology teachers were the subjects of this investigation. Allen and Amber obtained their certification through an alternative summer training institute in consecutive years. Tiffany and Tricia obtained their certification through a traditional, graduate level training program in consecutive years. Both programs were offered at the same northeastern state university. Participants contributed to six data gathering techniques including an initial semi-structured interview, responses to the Conceptions of Teaching Science questionnaire (Hewson & Hewson, 1989), three videotaped biology lessons, evaluation of three corresponding lesson plans, and a final semi-structured interview conducted at the end of the investigation. An informal, end-of-study survey intended to offer participants an opportunity to disclose their thoughts and needs as first year teachers was also employed. Results indicate that while conceptions of teaching science may vary slightly among participants, there is no evidence to suggest that

  7. The implementation of equitable teaching strategies by high school biology student teachers

    NASA Astrophysics Data System (ADS)

    Scantlebury, Kate; Butler Kahle, Jane

    Teachers can perpetuate stereotypic cultural beliefs regarding girls' ability in, aptitude for, and suitability for science by their teaching practices and behaviors. As teachers have a major influence on girls' career choices their equitable teaching practices in the classroom are important to encourage all students, but especially girls, to continue with science. Researchers have studied science classrooms and have defined common strategies and practices that can help create an equitable classroom environment. The purpose of this study was to determine if high school biology student teachers could transfer learned equitable teaching strategies to actual teaching and the support conditions necessary for that transfer. Two support conditions were assessed: cooperating teacher and peer group support. Seven preservice teachers were placed into three groups. One group had both support conditions, the second group had only one condition (peer support), and the third group did not have either support condition. Both qualitative and quantitative data sources were collected. Results showed that preservice teachers could transfer learned equitable teaching into actual teaching practice. However, they were more successful in achieving the transfer if they were supervised by cooperating teachers who are sensitized to the issue of gender equity in education. Being involved in a peer support group was not as crucial to using the strategies as having a supportive cooperative teacher.

  4. An analysis of learning in an online biology course for teachers and teacher candidates: A mixed methods approach

    NASA Astrophysics Data System (ADS)

    Lebec, Michael Thomas

    Due to discipline specific shortages, web-based learning has been proposed as a convenient way to upgrade the content knowledge of instructors interested in learning to teach science. Despite quantitative evidence that web-based instruction is equivalent to traditional methods, questions remain regarding its use. The efficiency and practicality of this approach with teachers in particular has not been extensively studied. This investigation examines learning in an online biology course designed to help teachers prepare for science certification exams. Research questions concern flow teachers learn biology in the online environment and how this setting influences the learning process. Quantitative and qualitative methodologies are employed in an attempt to provide a more complete perspective than typical studies of online learning. Concept maps, tests, and online discussion transcripts are compared as measures of assimilated knowledge, while interviews reflect participants' views on the course. Findings indicate that participants experienced gains in declarative knowledge, but little improvement with respect to conditional knowledge. Qualitative examination of concept maps demonstrates gaps in participants' understandings of key course ideas. Engagement in the use of online resources varied according to participants' attitudes towards online learning. Subjects also reported a lack of motivation to fully engage in the course due to busy teaching schedules and the absence of accountability.

  5. Online information seeking practices of biology teachers and the perceived influences on instructional planning

    NASA Astrophysics Data System (ADS)

    Perrault, Anne Marie

    The purpose of this study was to examine biology teachers' perceptions of how their online information seeking practices influence their instructional planning. When teachers engage in activities to locate, evaluate, and use online information and resources, a myriad of inter-related and often inseparable consequences follows. These influences may be any combination of direct/indirect, desirable/undesirable, or anticipated/unanticipated (Rogers, 2003). This exploratory study collected baseline data regarding teachers' online practices and its influence on their practice. There were two phases of data collection in this study. Phase I was an online survey of more than seventy New York State biology teachers. The survey was intended to capture (1) a snapshot of the biology teachers' online information seeking practices during the summer and fall 2004, and (2) their perceptions regarding how their online practices influenced their instructional planning. In Phase II, ten study participants were interviewed in order to explore in greater detail the consequences of their online information seeking practices on their instructional planning. Four themes reflecting the consequences of teachers' information seeking practices emerged from the data analysis: Currency of Information; Sparking of Ideas and Gaining Personal Knowledge; Resource Management and the Role of Time; and Webs of Sharing. Each theme encompassed both the purposeful and the indirect actions by teachers to access knowledge and resources to refine and improve their instructional planning. This study's findings show that teachers are using a greater number and wider range of current and multi-modal resources than pre-Internet and they perceive this as an advantage in creating authentic, inquiry-based learning experiences. A notable discovery was of the under-use by teachers of educational online resources specifically designed to support teaching and learning activities (e.g., digital libraries, online

  6. Examining beginning biology teachers' knowledge, beliefs, and practice for teaching natural selection

    NASA Astrophysics Data System (ADS)

    Sickel, Aaron J.

    The teacher is the most important school-based factor in student learning. Thus, in order to improve student learning, we must examine how teachers learn to teach. My overarching research agenda centers upon K-16 science teacher learning and development. Within this agenda, I conduct studies focused on two strands of research: 1) How teachers learn to teach science using constructivist and inquiry-oriented teaching strategies; and 2) How teachers learn to teach biological evolution. This dissertation merges the two strands together, and consists of four related manuscripts that address how beginning biology teachers learn to teach natural selection using constructivist and inquiry-oriented teaching strategies. In the first manuscript, I reviewed the evolution education literature focused on K-12 teachers’ knowledge, beliefs, and practice for teaching evolution. Based upon findings across the studies, I articulated five goals for preparing teachers to teach evolution. The second and third manuscripts are longitudinal empirical studies focused on three beginning biology teachers learning to teach natural selection using the 5E instructional model and interactive classroom simulations. The fourth manuscript is a practitioner article that explains how to teach natural selection simulations using a constructivist, analogy-based teaching strategy. Findings that cut across the four manuscripts are organized into the following themes: (A) The participants developed some common types of knowledge for teaching natural selection, yet also developed in unique ways. All participants developed knowledge of the horizontal curriculum. Yet, participants also developed different types of knowledge. For example, participants who had taken an evolution course developed more integrated pedagogical content knowledge for teaching the core concepts of natural selection. The participant who integrated discipline-level knowledge for teaching science through inquiry with topic

    PubMed

    Dekker, Sanne; Jolles, Jelle

    2015-01-01

    This study evaluated a new teaching module about "Brain and Learning" using a controlled design. The module was implemented in high school biology classes and comprised three lessons: (1) brain processes underlying learning; (2) neuropsychological development during adolescence; and (3) lifestyle factors that influence learning performance. Participants were 32 biology teachers who were interested in "Brain and Learning" and 1241 students in grades 8-9. Teachers' knowledge and students' beliefs about learning potential were examined using online questionnaires. Results indicated that before intervention, biology teachers were significantly less familiar with how the brain functions and develops than with its structure and with basic neuroscientific concepts (46 vs. 75% correct answers). After intervention, teachers' knowledge of "Brain and Learning" had significantly increased (64%), and more students believed that intelligence is malleable (incremental theory). This emphasizes the potential value of a short teaching module, both for improving biology teachers' insights into "Brain and Learning," and for changing students' beliefs about intelligence.

    2014-09-01

    Teachers' content-related knowledge is a key factor influencing the learning progress of students. Different models of content-related knowledge have been proposed by educational researchers; most of them take into account three categories: content knowledge, pedagogical content knowledge, and curricular knowledge. As there is no consensus about the empirical separability (i.e. empirical structure) of content-related knowledge yet, a total of 134 biology teachers from secondary schools completed three tests which were to capture each of the three categories of content-related knowledge. The empirical structure of content-related knowledge was analyzed by Rasch analysis, which suggests content-related knowledge to be composed of (1) content knowledge, (2) pedagogical content knowledge, and (3) curricular knowledge. Pedagogical content knowledge and curricular knowledge are highly related (rlatent = .70). The latent correlations between content knowledge and pedagogical content knowledge (rlatent = .48)-and curricular knowledge, respectively (rlatent = .35)-are moderate to low (all ps < .001). Beyond the empirical structure of content-related knowledge, different learning opportunities for teachers were investigated with regard to their relationship to content knowledge, pedagogical content knowledge, and curricular knowledge acquisition. Our results show that an in-depth training in teacher education, professional development, and teacher self-study are positively related to particular categories of content-related knowledge. Furthermore, our results indicate that teaching experience is negatively related to curricular knowledge, compared to no significant relationship with content knowledge and pedagogical content knowledge.

    The aim of this study was to compare ochratoxin A (OTA) levels in pig tissues and biological fluids after animal exposure to contaminated diet (250 μg OTA/kg of feed) during 4 weeks of fattening. OTA concentrations were quantified using a validated immunoassay method (ELISA) and high-performance liquid chromatography with fluorescence detector (HPLC-FD). The highest mean OTA concentration in pig tissues was determined in kidneys of exposed animals (13.87 ± 1.41 μg/kg), followed by lungs (10.47 ± 1.97 μg/kg), liver (7.28 ± 1.75 μg/kg), spleen (4.81 ± 0.99 μg/kg), muscle tissue (4.72 ± 0.86 μg/kg), fat tissue (4.11 ± 0.88 μg/kg), heart (3.71 ± 1.09 μg/kg), and brain (3.01 ± 0.25 μg/kg). Furthermore, on the last day of exposure (day 28), significantly higher mean OTA levels were determined in urine (16.06 ± 3.09 μg/L) in comparison to serum (4.77 ± 1.57 μg/L) showing that OTA urine analysis could be a good marker to identify elevated levels of this contaminant in porcine tissues used for human consumption. This study gave guidelines for the most efficient OTA control in pig-derived biological materials that can be exercised at slaughterhouses. PMID:27056395

  17. Examining the pedagogical content knowledge and practice of experienced secondary biology teachers for teaching diffusion and osmosis

    NASA Astrophysics Data System (ADS)

    Lankford, Deanna

    Teachers are the most important factor in student learning (National Research Council, 1996); yet little is known about the specialized knowledge held by experienced teachers. The purpose of this study was twofold: first, to make explicit the pedagogical content knowledge (PCK) for teaching diffusion and osmosis held by experienced biology teachers and, second, to reveal how topic-specific PCK informs teacher practice. The Magnusson et al. (1999) PCK model served as the theoretical framework for the study. The overarching research question was: When teaching lessons on osmosis and diffusion, how do experienced biology teachers draw upon their topic-specific pedagogical content knowledge? Data sources included observations of two consecutive lessons, three semi-structured interviews, lesson plans, and student handouts. Data analysis indicated five of the six teachers held a constructivist orientation to science teaching and engaged students in explorations of diffusion and osmosis prior to introducing the concepts to students. Explanations for diffusion and osmosis were based upon students' observations and experiences during explorations. All six teachers used representations at the molecular, cellular, and plant organ levels to serve as foci for explorations of diffusion and osmosis. Three potential learning difficulties identified by the teachers included: (a) understanding vocabulary terms, (b) predicting the direction of osmosis, and (c) identifying random molecular motion as the driving force for diffusion and osmosis. Participants used student predictions as formative assessments to reveal misconceptions before instruction and evaluate conceptual understanding during instruction. This study includes implications for teacher preparation, research, and policy.

  19. Educative Mentoring: How a Mentor Supported a Preservice Biology Teacher's Pedagogical Content Knowledge Development

    NASA Astrophysics Data System (ADS)

    Barnett, Ellen; Friedrichsen, Patricia J.

    2015-11-01

    Research suggests discipline-specific, educative mentoring can help preservice teachers develop more sophisticated pedagogical content knowledge (PCK). However, there are few studies examining the nature of mentors' practice and how mentors influence preservice teacher's (PST) PCK. The purpose of this case study was to describe the strategies used by a secondary biology mentor teacher to support the development of a PST's PCK. The primary data sources were the transcripts of audio-recorded, daily meetings between the mentor and the PST during two curriculum units: DNA/Protein Synthesis and Evolution. The mentor influenced the PST's teaching orientation by repeatedly comparing teacher- and student-centered approaches, asking him to consider how students learn, and asking him to self-assess whether his instruction aligned with his teaching beliefs. The mentor helped the PST develop topic-specific knowledge of instructional strategies by sharing strategies she used previously, modeling critical reflection, and inviting him to critically reflect on his own instructional strategies. Topic-specific knowledge of students' understanding of science was developed by discussing common student misconceptions revealed in students' conversations and by sharing the results of test-item analysis from previous unit tests. The mentor helped develop the PST's topic-specific knowledge of assessment by helping him critically analyze and revise previous examinations to better align with the current curriculum units. Topic-specific knowledge of curricula was developed by jointly grappling with decisions about concept sequencing within units. The study includes implications for research, science teacher education, and professional development for mentors.

    2002-09-01

    This study examined the amount of emphasis given by Arizona high school biology teachers to the topics of evolutionary theory and special creation, as explanations for the origin and diversity of life on earth. A questionnaire was mailed to all Arizona public high school biology teachers in March of 2000, to gather data on teachers' classroom practices and attitudes towards evolution and creation, information on teachers' educational and professional backgrounds, their religious preferences, and any perceptions of pressure regarding the teaching of evolution or creation from outside sources. Sixty-five percent (final n = 419) of the questionnaires were returned. Analysis confirmed that, while a strong majority (96%) of Arizona teachers gave some coverage to evolutionary theory, a significant proportion (33%) reported fewer than three class periods per semester in which evolution was a major topic; 10% left it out entirely. Fourteen percent of the teachers reported that they gave moderate-to-strong emphasis to religious explanations of the origins and diversity of life. It was unclear whether this was presented as an alternative scientific theory, or as religion or philosophy. Between ten and thirty percent also rejected the scientific validity of evolutionary theory, rejected the evolution of humans from ape-like ancestors, thought that religious explanations should be taught as part of high school biology classes, or agreed that creationism has a valid scientific foundation. The amount of emphasis given evolution by a teacher correlated positively with teaching experience, number of college classes in evolutionary biology taken by the teacher, the amount of in-service training a teacher had had on teaching evolutionary theory, and age. It correlated negatively with membership in Conservative Christian religious denominations and with degree of religious fervor. Interestingly, the possession of a degree in biological sciences (e.g., versus a degree in education

  2. Group processing in an undergraduate biology course for preservice teachers: Experiences and attitudes

    NASA Astrophysics Data System (ADS)

    Schellenberger, Lauren Brownback

    Group processing is a key principle of cooperative learning in which small groups discuss their strengths and weaknesses and set group goals or norms. However, group processing has not been well-studied at the post-secondary level or from a qualitative or mixed methods perspective. This mixed methods study uses a phenomenological framework to examine the experience of group processing for students in an undergraduate biology course for preservice teachers. The effect of group processing on students' attitudes toward future group work and group processing is also examined. Additionally, this research investigated preservice teachers' plans for incorporating group processing into future lessons. Students primarily experienced group processing as a time to reflect on past performance. Also, students experienced group processing as a time to increase communication among group members and become motivated for future group assignments. Three factors directly influenced students' experiences with group processing: (1) previous experience with group work, (2) instructor interaction, and (3) gender. Survey data indicated that group processing had a slight positive effect on students' attitudes toward future group work and group processing. Participants who were interviewed felt that group processing was an important part of group work and that it had increased their group's effectiveness as well as their ability to work effectively with other people. Participants held positive views on group work prior to engaging in group processing, and group processing did not alter their atittude toward group work. Preservice teachers who were interviewed planned to use group work and a modified group processing protocol in their future classrooms. They also felt that group processing had prepared them for their future professions by modeling effective collaboration and group skills. Based on this research, a new model for group processing has been created which includes extensive

  3. The role of external pressure and support on teacher choices related to evolution curriculum in the secondary biology classroom

    NASA Astrophysics Data System (ADS)

    Oschman, Scot

    The scientific community strongly and virtually universally supports the teaching of biological evolution in our public schools. However, there are many in the general public who object to the teaching of biological evolution in our nation's science classrooms. Groups such as Answers in Genesis and the Discovery Institute, along with parents, students, school boards, and school administrators are alleged by many in the scientific and science education communities to be pressuring teachers in a variety of ways regarding the teaching of evolution. The purpose of this study was to examine the sources of, extent of, and ways in which science teachers deal with external influences that attempt to alter their science curriculum related to the teaching of the theory of biological evolution in order to support it, deemphasize it or remove it from their classrooms. It also attempted to determine the impact these outside influences have on evolution education in the classroom. Internal influences were examined in order to ascertain other possible reasons why teachers might or might not de-emphasize, omit, or teach evidence contrary to evolution. Two thousand cover letters were sent out to high school biology teachers selected at random from three states in the U.S. Registry of Teachers, directing them to a web site where they could complete the questionnaire online. One hundred seventy eight teachers responded to the survey. The statistical analyses used in this study to examine the results included analysis of variance (ANOVA), independent samples t tests for means comparisons, as well as a variety of descriptive statistics. This study found that 59% of the teachers who responded had experienced some form of pressure related to their evolution curriculum, and that the majority of this pressure came from students, groups or individuals not affiliated with their school district, and parents. The most common manifestations of pressure were to teach that evolution was "only" a

    2001-03-01

    For the past 15 years Kansas State University has offered a course in modern physics for students who are not majoring in physics. This course carries a prerequisite of one physics course so that the students have a basic introduction in classical topics. The majors of students range from liberal arts to engineering. Future secondary science teachers whose first area of teaching is not physics can use the course as part of their study of science. The course has evolved from a lecture format to one which is highly interactive and uses a combination of hands-on activities, tutorials and visualizations, particularly the Visual Quantum Mechanics materials. Another course encourages biology students to continue their physics learning beyond the introductory course. Modern Miracle Medical Machines introduces the basic physics which underlie diagnosis techniques such as MRI and PET and laser surgical techniques.

    2006-10-30

    This project achieved its goal of implementing a nationwide training program to introduce high school biology teachers to the key uses and societal implications of human DNA polymorphisms. The 2.5-day workshop introduced high school biology faculty to a laboratory-based unit on human DNA polymorphisms – which provides a uniquely personal perspective on the science and Ethical, Legal and Social Implications (ELSI) of the Human Genome Project. As proposed, 12 workshops were conducted at venues across the United States. The workshops were attended by 256 high school faculty, exceeding proposed attendance of 240 by 7%. Each workshop mixed theoretical, laboratory, and computer work with practical and ethical implications. Program participants learned simplified lab techniques for amplifying three types of chromosomal polymorphisms: an Alu insertion (PV92), a VNTR (pMCT118/D1S80), and single nucleotide polymorphisms (SNPs) in the mitochondrial control region. These polymorphisms illustrate the use of DNA variations in disease diagnosis, forensic biology, and identity testing - and provide a starting point for discussing the uses and potential abuses of genetic technology. Participants also learned how to use their Alu and mitochondrial data as an entrée to human population genetics and evolution. Our work to simplify lab techniques for amplifying human DNA polymorphisms in educational settings culminated with the release in 1998 of three Advanced Technology (AT) PCR kits by Carolina Biological Supply Company, the nation’s oldest educational science supplier. The kits use a simple 30-minute method to isolate template DNA from hair sheaths or buccal cells and streamlined PCR chemistry based on Pharmacia Ready-To-Go Beads, which incorporate Taq polymerase, deoxynucleotide triphosphates, and buffer in a freeze-dried pellet. These kits have greatly simplified teacher implementation of human PCR labs, and their use is growing at a rapid pace. Sales of human polymorphism

  6. Lecture to inquiry: The transformation of a tech prep biology teacher

    NASA Astrophysics Data System (ADS)

    Haskell, Deborah Harris

    As teachers implement the National Science Education Standards (NRC, 1996) many have to reform the instructional methods they have used throughout their careers. This case study examines the transformation of Laurie, a 20-year teacher, during her first year of change from a "traditional" textbook/lecture style of teaching to a facilitator of an inquiry-based classroom. Implementing change requires not only pedagogical expertise, but also the belief that the modifications can be made and that the outcomes are significant. Using Bandura's social cognitive theory as a framework, changes in Laurie's self-efficacy, outcome expectancy, and motivation are followed throughout the transition. During her first year of change, Laurie used worksheets, small group activities, and guided inquiry activities, all strategies in which she had high self-efficacy and experienced positive student outcomes. She rarely used class forums, authentic assessment, and formative assessment. Factors that influenced her change were experiential professional development opportunities that allowed her to practice inquiry-based techniques, a change in her teaching environment from college prep chemistry to tech prep biology, autonomy regarding classroom decisions, and reflective decision making as she learned through experience. Using a standards-based biology textbook increased her self-efficacy toward using inquiry-based practices. The textbook format of embedding text in activities rather than adding activities to the text resulted in an increase of the number and frequency of activities done. Facilitating the textbook's Guided Inquiries and Extended Inquiries helped Laurie gain experience with inquiry-based methods. She also realized that when building from the students' concrete experiences, her students were able to attain higher-level thinking skills. The study revealed six factors contributing to Laurie's change process: (a) experiential professional development, (b) motivation for change

  18. Epistemological Predictors of "Self Efficacy on Learning Biology" and "Test Anxiety Related to Evaluation of Learning on Biology" for Pre-service Elementary Teachers

    NASA Astrophysics Data System (ADS)

    Köksal, Mustafa Serdar

    2011-11-01

    The degree to which pre-service teachers learn biology is related to both motivational factors of self-regulation and factors regarding epistemological beliefs. At the same time, self-regulation and epistemological beliefs are also associated with one another. Based on this relationship, the purpose of this study was to investigate the relationship between components of epistemological beliefs and self-refulation (self-efficacy and test-anxiety) on learning biology. The study was conducted with 411 pre-service elementary and pre-service elementary science teachers by using a predictive research approach. Collected data was analyzed by the multiple linear regression technique. The results showed that only the belief about "existence of one truth" was a significant predictor of test anxiety while there was no epistemological predictor of self-efficacy. Conclusions and implications of the study will be discussed.

  19. The Science and Issues of Human DNA Polymorphisms: A Training Workshop for High School Biology Teachers

    SciTech Connect

    Micklos, David A.

    2006-10-30

    This project achieved its goal of implementing a nationwide training program to introduce high school biology teachers to the key uses and societal implications of human DNA polymorphisms. The 2.5-day workshop introduced high school biology faculty to a laboratory-based unit on human DNA polymorphisms â which provides a uniquely personal perspective on the science and Ethical, Legal and Social Implications (ELSI) of the Human Genome Project. As proposed, 12 workshops were conducted at venues across the United States. The workshops were attended by 256 high school faculty, exceeding proposed attendance of 240 by 7%. Each workshop mixed theoretical, laboratory, and computer work with practical and ethical implications. Program participants learned simplified lab techniques for amplifying three types of chromosomal polymorphisms: an Alu insertion (PV92), a VNTR (pMCT118/D1S80), and single nucleotide polymorphisms (SNPs) in the mitochondrial control region. These polymorphisms illustrate the use of DNA variations in disease diagnosis, forensic biology, and identity testing - and provide a starting point for discussing the uses and potential abuses of genetic technology. Participants also learned how to use their Alu and mitochondrial data as an entrée to human population genetics and evolution. Our work to simplify lab techniques for amplifying human DNA polymorphisms in educational settings culminated with the release in 1998 of three Advanced Technology (AT) PCR kits by Carolina Biological Supply Company, the nationâÂÂs oldest educational science supplier. The kits use a simple 30-minute method to isolate template DNA from hair sheaths or buccal cells and streamlined PCR chemistry based on Pharmacia Ready-To-Go Beads, which incorporate Taq polymerase, deoxynucleotide triphosphates, and buffer in a freeze-dried pellet. These kits have greatly simplified teacher implementation of human PCR labs, and their use is growing at a rapid pace. Sales of human

  3. Evolution in the Caribbean Classroom: A critical analysis of the role of biology teachers and science standards in shaping evolution instruction in Belize

    NASA Astrophysics Data System (ADS)

    Nunez, Elvis Enrique; Pringle, Rose M.; Showalter, Kevin Tyler

    2012-10-01

    A survey of the literature on evolution instruction provides evidence that teachers' personal views and understandings can shape instructional approaches and content delivered in science classrooms regardless of established science standards. This study is the first to quantify evolutionary worldviews of in-service teachers in the Caribbean, specifically in Belize, an English-speaking nation with a high school system guided by a regional biology syllabus and strict standardized tests. Using the Measure of Acceptance of the Theory of Evolution (MATE) instrument and knowledge test, we investigated (1) the current level of acceptance and understanding of evolution as given by 97% of high school biology teachers in Belize; (2) the factors associated with acceptance and understanding of evolutionary theory. With an average MATE score of 64.4 and a mean knowledge score of 47.9%, Belizean teachers were classified as having both 'Low Acceptance' and 'Low Understanding' of evolutionary theory. A positive correlation was found between teacher acceptance and understanding of evolution. A review of the Caribbean Secondary Examination Certificate biology syllabus suggests that evolution plays a minimal role in the high school biology classroom. We believe that Belize presents a unique opening for future training on evolution instruction since 57% of the biology teachers self-proclaim to be unprepared to teach evolution. The results of this study have implications for policy, practice and research with teachers' acceptance, understanding and confidence in teaching evolution serving as important predictors for instructional approaches used in the biology classroom.

    2007-10-01

    This study investigated whether or not an increase in secondary science teacher knowledge about evolution and the nature of science gained from completing a graduate-level evolution course was associated with greater preference for the teaching of evolution in schools. Forty-four precertified secondary biology teachers participated in a 14-week intervention designed to address documented misconceptions identified by a precourse instrument. The course produced statistically significant gains in teacher knowledge of evolution and the nature of science and a significant decrease in misconceptions about evolution and natural selection. Nevertheless, teachers’ postcourse preference positions remained unchanged; the majority of science teachers still preferred that antievolutionary ideas be taught in school.

  13. Student and Teacher Perceptions of a Mobile-Based Biology Vocabulary Study Tool for English Language Learners

    NASA Astrophysics Data System (ADS)

    Cruz, Maria B.

    English language learners studying biology face a dual challenge of mastering both content and language. Teaching ELLs how to engage in scientific discourse using appropriate language to ask, answer, explain, and make predictions about science requires a foundational knowledge of content-specific vocabulary. This study used qualitative interviews with intermediate-level ELLs at an American high school to learn how a supplemental iPod-based vocabulary review tool influenced their perceptions of learning biology vocabulary outside of classroom hours. Interviews with their biology teacher were also used to complement student testimony from the point of view of an educational professional with ELL teaching experience. Past studies in the area of mobile learning have primarily employed questionnaires to gather feedback from participants. This research study adds greater participant voice to the body of literature that encompasses mobile language learning, second language acquisition, and science education by presenting nuanced opinions from both students and teachers. This dissertation concludes with a discussion on the influence that this study could have on further research in the fields of mobile learning, academic vocabulary, and student learning behaviors.

    Wyner, Yael

    2013-08-01

    This study examines how the implementation of a novel curriculum, that emphasizes the use of published scientific data and media to learn about human impact and ecological function, influenced ninth-grade biology teacher ( N-36) dispositions toward using data and media in their ecology and human impact lesson plans. It explores how integration of these elements shaped their lesson plans. Research questions addressed are 1. How do teachers' use of data and media change as a result of implementing this novel curriculum? 2. How do the integration of data and media influence teachers' lesson plans? Findings show that implementation positively affected teachers' dispositions toward using authentic data and real-world media about scientific research to explain how people impact ecological function. Teachers also demonstrated increased appreciation and capacity for using data and media for learning how humans disrupt ecological function. Importantly, prior to implementation, 42 % of teachers specifically reported not using data when teaching human impact. Additionally, content analysis of teachers' lesson plan reports shows that focusing lesson plans around data and media can support teachers in making human impact lessons more specific and that a data- and media-centered curriculum can assist teachers in moving away from discussions of the generalized effect of people on the environment to specific real-world examples of how humans impact ecological function.

    PubMed Central

    Dekker, Sanne; Jolles, Jelle

    2015-01-01

    This study evaluated a new teaching module about “Brain and Learning” using a controlled design. The module was implemented in high school biology classes and comprised three lessons: (1) brain processes underlying learning; (2) neuropsychological development during adolescence; and (3) lifestyle factors that influence learning performance. Participants were 32 biology teachers who were interested in “Brain and Learning” and 1241 students in grades 8–9. Teachers' knowledge and students' beliefs about learning potential were examined using online questionnaires. Results indicated that before intervention, biology teachers were significantly less familiar with how the brain functions and develops than with its structure and with basic neuroscientific concepts (46 vs. 75% correct answers). After intervention, teachers' knowledge of “Brain and Learning” had significantly increased (64%), and more students believed that intelligence is malleable (incremental theory). This emphasizes the potential value of a short teaching module, both for improving biology teachers' insights into “Brain and Learning,” and for changing students' beliefs about intelligence.

    NASA Astrophysics Data System (ADS)

    Pavez, José M.; Vergara, Claudia A.; Santibañez, David; Cofré, Hernán

    2016-05-01

    A number of authors have recognized the importance of understanding the nature of science (NOS) for scientific literacy. Different instructional strategies such as decontextualized, hands-on inquiry, and history of science (HOS) activities have been proposed for teaching NOS. This article seeks to understand the contribution of HOS in enhancing biology teachers' understanding of NOS, and their perceptions about using HOS to teach NOS. These teachers ( N = 8), enrolled in a professional development program in Chile are, according to the national curriculum, expected to teach NOS, but have no specific NOS and HOS training. Teachers' views of NOS were assessed using the VNOS-D+ questionnaire at the beginning and at the end of two modules about science instruction and NOS. Both the pre- and the post-test were accompanied by interviews, and in the second session we collected information about teachers' perceptions of which interventions had been more significant in changing their views on NOS. Finally, the teachers also had to prepare a lesson plan for teaching NOS that included HOS. Some of the most important study results were: significant improvements were observed in teachers' understanding of NOS, although they assigned different levels of importance to HOS in these improvements; and although the teachers improved their understanding of NOS, most had difficulties in planning lessons about NOS and articulating historical episodes that incorporated NOS. The relationship between teachers' improved understanding of NOS and their instructional NOS skills is also discussed.

    As twenty-first century skills become a greater focus in K-12 education, an infusion of technology that meets the needs of today's students is paramount. This study looks at the design and creation of a Multiplayer Educational Gaming Application (MEGA) for high school biology students. The quasi-experimental, qualitative design assessed the twenty-first century skills of digital age literacy, inventive thinking, high productivity, and effective communication techniques of the students exposed to a MEGA. Three factors, as they pertained to these skills, emerged from classroom observations. Interaction with the teacher, discussion with peers, and engagement/time-on-task while playing the MEGA suggested that students playing an educational video game exhibited all of the projected twenty-first century skills while being engrossed in the embedded science content.

  10. When world views collide: A study of interdepartmental collaboration to develop a biology course for prospective elementary school teachers

    NASA Astrophysics Data System (ADS)

    Mattson, Susan Augusta

    As we near the 21st century, the nation's educational system continues to be in a state of flux. Recently, colleges and universities, whose previous involvement in mainstream educational reform has been more or less tangential, have become targets for change at what many believe to be the heart of problems in K-12 education: the preparation of prospective teachers. Science education is one area where change in teacher preparation is of critical concern. One emerging model for change involves collaboration between previously disparate academic departments: those situated in Colleges of Education and those situated in Colleges of Arts and Sciences. This dissertation focuses on one example of interdepartmental collaboration to develop a biology course, BIO 101, for prospective elementary school teachers. A team of course developers composed of representatives from different colleges in a major university served as the primary focus group for this study. Using interpretive research methodologies, the following research questions guided this study: (1) What perspectives characterized the development of BIO 101? (2) What beliefs about key issues were associated with different perspectives? (2) How did these beliefs shape the process and outcome of course development? (4) What were the implications of these beliefs for addressing goals for reform in science education? (5) What strategies can be used to encourage continued progress reform? The outcome of this study indicates that course development was characterized broadly by what can be considered either traditional or progressive perspectives. Specific beliefs underlying these perspectives influenced how the issues of content, pedagogy, and assessment were resolved during the development phase. Overall, the resolution of these issues reflected more traditional perspectives on science teaching and learning--particularly in approaches to content and assessment. Approaches to pedagogy varied according to course "units

  16. The effect of student-centered and teacher-centered instruction with and without conceptual advocacy on biology students' misconceptions, achievement, attitudes toward science, and cognitive retention

    NASA Astrophysics Data System (ADS)

    Gallop, Roger Graham

    The purpose of this study was to investigate the effect of student-centered and teacher-centered instructional strategies with and without conceptual advocacy (CA) on ninth-grade biology students' misconceptions (MIS), biology achievement (ACH), attitudes toward science (ATT), and cognitive retention of scientific method and measurement, spontaneous generation, and characteristics of living things. Students were purposively selected using intact classes and assigned to one of four treatment groups (i.e., student-centered instruction without CA, student-centered instruction with CA, teacher-centered instruction with CA, and teacher-centered instruction without CA). A modified quasi-experimental design was used in which students were not matched in the conventional sense but instead, groups were shown to be equivalent on the dependent measure via a pretest. A 5-day treatment implementation period addressed science conceptions under investigation. The treatment period was based on the number of class periods teachers at the target school actually spend teaching the biological concepts under investigation using traditional instruction. At the end of the treatment period, students were posttested using the Concepts in Biology instrument and Science Questionnaire. Eight weeks after the posttest, these instruments were administered again as a delayed posttest to determine cognitive retention of the correct biological conceptions and attitudes toward science. MANCOVA and follow-up univariate ANCOVA results indicated that student-centered instruction without CA (i.e., Group 1) did not have a significant effect on students' MIS, ACH, and ATT (F = .029, p = .8658; F = .002, p =.9688, F = .292, p = .5897, respectively). On the other hand, student-centered instruction with CA (i.e., Group 2) had a significant effect on students' MIS and ACH (F =10.33, p = .0016 and F = 10.17, p = .0017, respectively), but did not on ATT (F = .433, p = .5117).

    During summer 2010, a two-week-long scientific workshop "From educational to scientific perspectives: sugar polymers in biology and their applications" was offered for high school teachers and students at the University of Arkansas at Little Rock's Department of Biology. Teacher and student participants took part in science, technology, engineering, and mathematics (STEM) activities in order to improve math and science skills. Participants were taught various laboratory techniques, computer skills, Public Medical library searches, individual research project, PowerPoint presentation preparation, and a final oral presentation. Each participant was given pre- and post-workshop questionnaires, to gage initial and acquired knowledge. From the questionnaires, it was determined that there was a significant gain in knowledge of basic scientific concepts related to sugar polymers and their applications. It was found that 100% of participants—five teachers and seven students—reported their overall STEM experience as favorable. Furthermore, participants reported that the research project, computer techniques, and PowerPoint presentations were useful. This research experience provides knowledge about basic scientific concepts and is an excellent method to bridge the gap between high school and post-secondary education for both teachers and students.

  1. The effects of student-led and teacher-led advance organizers on students' achievement and motivation of high school biology students

    NASA Astrophysics Data System (ADS)

    Hopkins, Melody Denise

    The purpose of this research study was to explore what effects student-led and teacher-led advance organizer's instruction had on students' achievement and motivation in a high school biology class. The study used three advance organizers - Venn diagrams, concept maps, and KWL charts. There was a total of 83 students who participated in this study, and were enrolled in four sections of high school biology. The students were divided into two groups using systematic matching and received different advance organizer's instruction. Two groups received student-led instruction using cooperative learning, whereas, the other two groups received teacher-led instruction. Each group received a pretest, Advance Organizer Motivation Survey, weekly advance organizer-based lessons and weekly advance organizer evaluations for six weeks, posttest, and Advance Organizer Motivation Survey. Pretest and posttest scores on the biology exam, weekly objective quizzes, and presurvey and postsurvey scores on the Advance Organizer Motivation Survey were collected. Statistical analyses found no overall statistically significant difference in achievement between groups. When looking at achievement results for redundant organizers it was found that the student-led group had a higher mean than the teacher-led group when working with concept maps. Furthermore, there was a statistically significant difference in students' motivation to learn and motivation to participate in student-led activities between groups. The student-led group reported higher motivation than the teacher-led group. In regard to motivation and kinds of advance organizers, Venn diagrams and concept maps showed a statistically significant difference between groups, with the student-led group possessing more motivated with those two kinds of advance organizers than the teacher-led group. Qualitative data were also collected through weekly advance organizer evaluations, Advance Organizer Motivation Survey, and focus groups. These

    Biological energy flow has been notoriously difficult to teach. Our approach to this topic relies on abiotic and biotic examples of the energy released by moving electrons in thermodynamically spontaneous reactions. A series of analogical model-building experiences was supported with common language and representations including manipulatives. These materials were designed to help learners understand why electrons move in a hydrogen explosion and hydrogen fuel cell, so they could ultimately understand the rationale for energy transfer in the mitochondrion and the chloroplast. High school biology teachers attended a 2-wk Students Understanding eNergy (SUN) workshop during a randomized controlled trial. These treatment group teachers then took hydrogen fuel cells, manipulatives, and other materials into their regular biology classrooms. In this paper, we report significant gains in teacher knowledge and self-efficacy regarding biological energy transfer in the treatment group versus randomized controls. Significant effects on treatment group teacher knowledge and self-efficacy were found not only post–SUN workshop but even 1 yr later. Teacher knowledge was measured with both a multiple-choice exam and a drawing with a written explanation. Teacher confidence in their ability to teach biological energy transfer was measured by a modified form of the Science Teaching Efficacy Belief Instrument, In-Service A. Professional development implications regarding this topic are discussed. PMID:23737635

    Many of the goals and performance objectives for elementary science deal with hands-on experiences such as observing the characteristics of living things, sorting and classifying, and measuring and recording data. Ideal environments for learning episodes that can foster these objectives are zoos and parks or nature preserves. This poster describes a program that uses the University faculty, local master elementary teachers, and Zoo staff and facilities to: (1) educate K-6 teachers about zoology, ecology, and evolution, (2) provide practical, on-site learning exercises as examples of how teachers can develop zoo visits that will be true learning experiences, (3) help the participants develop zoo-related exercises of classroom use, (4) show the participants the behind-the scenes work that goes on at a zoo, and (5) establish a close rapport between the teachers and a large group of professional resource persons. We present the results of evaluations and follow-up interviews, and we note the key features of this program and suggest how our experience may be used by other partnerships.

  15. Teacher-student co-construction processes in biology: Strategies for developing mental models in large group discussions

    NASA Astrophysics Data System (ADS)

    Nunez Oviedo, Maria Cecilia

    The aim of this study was to describe co-construction processes in large group discussions. Co-construction, as used here, is a process by which the teacher and the students work together to construct and evaluate mental models of a target concept. Data were collected for an in-depth case study of a single teacher instructing middle school students with an innovative curriculum on human respiration. Data came from transcripts of video taped lessons, drawings, and pre- and post-test scores. Quantitative and qualitative analyses were conducted. In the quantitative analysis, differences in gains between one and two standard deviations in size were found between the pre- and post-test scores indicating that the students increased their understanding about human respiration. In the qualitative analysis, a generative exploratory method followed by a convergent coded method was conducted to examine teacher-student interaction patterns. The aim of this part was to determine how learning occurred by attempting to connect dialogue patterns with underlying cognitive processes. The main outcome of the study is a hypothesized model containing four layers of nested teaching strategies. Listed from large to small time scales these are: the Macro Cycle, the Co-construction Modes, the Micro Cycle, and the Teaching Tactics. The most intensive analysis focused on identifying and articulating the Co-construction Modes---Accretion Mode, Disconfirmation Mode, Modification Mode, Evolution Mode, and Competition Mode---and their relations to the other levels of the model. These modes can either describe the construction and evaluation of individual model elements or of entire models giving a total of ten modes. The frequency of these co-construction modes was then determined by coding, twenty-six hours of transcripts. The most frequent modes were the Accretion Mode and the Disconfirmation Mode. The teacher's and the students' contributions to the co-construction process were also examined

  19. The impact of teachers' approaches to teaching and students' learning styles on students' approaches to learning in college online biology courses

    NASA Astrophysics Data System (ADS)

    Hong, Yuh-Fong

    With the rapid growth of online courses in higher education institutions, research on quality of learning for online courses is needed. However, there is a notable lack of research in the cited literature providing evidence that online distance education promotes the quality of independent learning to which it aspires. Previous studies focused on academic outcomes and technology applications which do not monitor students' learning processes, such as their approaches to learning. Understanding students' learning processes and factors influencing quality of learning will provide valuable information for instructors and institutions in providing quality online courses and programs. The purpose of this study was to identify and investigate college biology teachers' approaches to teaching and students' learning styles, and to examine the impact of approaches to teaching and learning styles on students' approaches to learning via online instruction. Data collection included eighty-seven participants from five online biology courses at a community college in the southern area of Texas. Data analysis showed the following results. First, there were significant differences in approaches to learning among students with different learning styles. Second, there was a significant difference in students' approaches to learning between classes using different approaches to teaching. Three, the impact of learning styles on students' approaches to learning was not influenced by instructors' approaches to teaching. Two conclusions were obtained from the results. First, individuals with the ability to perceive information abstractly might be more likely to adopt deep approaches to learning than those preferring to perceive information through concrete experience in online learning environments. Second, Teaching Approach Inventory might not be suitable to measure approaches to teaching for online biology courses due to online instructional design and technology limitations. Based on

    NASA Astrophysics Data System (ADS)

    Danielsson, Anna T.; Andersson, Kristina; Gullberg, Annica; Hussénius, Anita; Scantlebury, Kathryn

    2015-10-01

    In this article we explore the places pre- and primary school (K-6) student teachers associate with their science learning experiences and how they view the relationship between these places and science. In doing so, we use `place' as an analytical entry point to deepen the understanding of pre- and primary school student teachers' relationship to science. Inspired by theories from human geography we firstly explore how the university science classroom can be conceptualised as a meeting place, where trajectories of people as well as artefacts come together, using this conceptualisation as the stepping stone for arguing the importance of the place-related narrations of science the students bring to this classroom. We thereafter analyse how a sense of place, including affective dimensions, is reflected in Swedish student teachers' science learning narratives (collected in the form of an essay assignment where the student teachers' reflected upon their in and out of school science learning experiences). The empirical material consists of 120 student essays. The most prominent feature of the empirical material as a whole is the abundance of affective stories about the student teachers' experiences in natural environments, often expressing a strong sense of belonging to, and identification with, a particular place. However, the student narratives also give voice to an ambivalent valuing of the affective experiences of natural environments. Sometimes such affective experiences are strongly delineated from what the students consider actual science knowledge, on other occasions, students, in a somewhat contradictious way, stress natural environments as the authentic place for doing science, in contrast to the perceived in-authenticity of teaching science in the classroom. When student teachers explicitly discuss the classroom as a place, this was almost without exception with strong negative emotions, experiences of outsideness and alienation.

  12. Virtual, on-line, frog dissection vs. conventional laboratory dissection: A comparison of student achievement and teacher perceptions among honors, general ability, and foundations-level high school biology classes

    Kopec, Ronald H.

    2002-09-01

    Dissecting animal specimens has long been a tradition in biology classes. Objections by students, based on religious or ethical grounds, have been raised regarding the dissections of animals in classroom laboratories. A number of states now have legal proceedings or statewide policies requiring that alternatives to the actual dissection of laboratory animal specimens be permitted in their school districts. Alternatives to actual dissections have been developed in recent years. For a variety of reasons, performing an actual or conventional animal dissection may not be a desirable option. The purpose of this study was to investigate how a virtual On-line frog dissection compares with an actual laboratory dissection. What were the perceptions of the teacher's using it? How does student achievement compare among three the different ability levels on a pre and posttest regarding basic frog anatomy? Is a virtual On-line dissection a suitable alternative for students who, for whatever reason, do not participate in the actual laboratory experience? The subjects consisted of 218 biology students among three different ability levels, in a Northeastern suburban high school. Approximately half of the student groups participated in a virtual On-line dissection, the other half in an actual laboratory dissection. A pretest of basic frog anatomy was administered to the students two days before and the posttest one day after their dissection experience. Data were analyzed using matched pairs t-Tests, Analysis of Variance, Tukey HSD, and Squared Curvilinear Coefficients. Survey questionnaires were administered to the teachers after the dissection experiences were completed. There were no significant differences found in achievement between the virtual and conventional dissection groups. There were significant differences found in achievement score means among the three ability levels. There was no significant interaction between gender and achievement. Perceptions of the teacher

Our findings are that prospective teachers want to take an active role in rejecting or supporting individual GMOs and are aware of the importance of education about genetically modified organism (GMO) items and their potential significance for society. Through cluster analysis, we recognized four clusters of GMOs, separated by degree of genetically modified acceptability. GM plants and microorganisms which are recognized as useful are accepted. They are undecided about organisms used in research or medicine and reject organisms used for food consumption and for fun. There are only weak correlations between knowledge and attitudes and knowledge and acceptance of GMOs, and a strong correlation between attitudes and acceptance. The appropriate strategies and actions for improving university courses in biotechnology are discussed. PMID:21567816

  20. The attitudinal and cognitive effects of interdisciplinary collaboration on elementary pre-service teachers development of biological science related lesson plans

    Mills, Jada Jamerson

    There is a need for STEM (science, technology, engineering, and mathematics) education to be taught effectively in elementary schools. In order to achieve this, teacher preparation programs should graduate confident, content strong teachers to convey knowledge to elementary students. This study used interdisciplinary collaboration between the School of Education and the College of Liberal Arts through a Learning-by-Teaching method (LdL): Lernen durch Lernen in German. Pre-service teacher (PST) achievement levels of understanding science concepts based on pretest and posttest data, quality of lesson plans developed, and enjoyment of the class based on the collaboration with science students. The PSTs enrolled in two treatment sections of EDEL 404: Science in the Elementary Classroom collaborated with science students enrolled in BISC 327: Introductory Neuroscience to enhance their science skills and create case-based lesson plans on neurothology topics: echolocation, electrosensory reception, steroid hormones, and vocal learning. The PSTs enrolled in the single control section of EDEL 404 collaborated with fellow elementary education majors to develop lesson plans also based on the same selected topics. Qualitative interviews of education faculty, science faculty, and PSTs provided depth to the quantitative findings. Upon lesson plan completion, in-service teachers also graded the two best and two worst plans for the treatment and control sections and a science reviewer graded the plans for scientific accuracy. Statistical analyses were conducted for hypotheses, and one significant hypothesis found that PSTs who collaborated with science students had more positive science lesson plan writing attitudes than those who did not. Despite overall insignificant statistical analyses, all PSTs responded as more confident after collaboration. Additionally, interviews provided meaning and understanding to the insignificant statistical results as well as scientific accuracy of

  17. Analyzing the high school biology education in Yemen

    NASA Astrophysics Data System (ADS)

    Saif, Abdulsalam Dael

    This study evaluated the high school biology education in Yemen based on the Biological Sciences Curriculum Study (BSCS) Developing Biological Literacy (1993). The study used inductive analysis, a type of qualitative research, in which triangulation of six data sources was used to answer the four research questions developed for the study. Twenty-four teachers and 48 students from four high schools in Yemen responded to the questionnaires. The findings of this study indicated that 44% of the BSCS goals suggested for a biology program is included in the biology education program in Yemen. Fifty-one percent of the concepts related to the unifying principles of biology were found in the three Yemeni high school biology textbooks. The high school biology teachers used 33% of instructional strategies and 40% of the assessment methods suggested in the BSCS guide. The majority of teachers and students reported that laboratory activities in the high school biology program are insufficient. However, most of the teachers' and students' responses indicated their interest in integrating environmental issues in biological concepts. Almost all of the teachers and students reported that the high school biology education in Yemen does not allow students to investigate independently or help them develop awareness of social problems related to biology. Four strategic plans were designed to improve the goals and curriculum content of high school biology education, the preparation of biology teachers, the enhancement of content and teaching skills of in-service teachers, and administrative support for facilities, equipment, and supplies for biology classes.

    To increase the teacher efficacy of student teachers, they need positive classroom experiences: mastery experiences. These mastery experiences have to be created by the student teachers themselves. Therefore, student teachers need a tool to better understand problematic teaching experiences and help them create positive classroom experiences. Nine student biology teachers used this attribution support tool when reflecting on multiple lessons taught in classes they considered difficult. They scored their lessons and filled in a teacher efficacy questionnaire after each lesson. The results show that teacher efficacy increased and the number of failures during the lessons decreased; on average, the self-awarded marks per teacher per lesson increased, indicating an increase in mastery experiences. Therefore, the attribution tool seems to be a promising tool for student teachers to enhance their teacher efficacy and to support reflection on problematic teaching experiences.

    Woese, Carl R.

    2004-01-01

    Biology today is at a crossroads. The molecular paradigm, which so successfully guided the discipline throughout most of the 20th century, is no longer a reliable guide. Its vision of biology now realized, the molecular paradigm has run its course. Biology, therefore, has a choice to make, between the comfortable path of continuing to follow molecular biology's lead or the more invigorating one of seeking a new and inspiring vision of the living world, one that addresses the major problems in biology that 20th century biology, molecular biology, could not handle and, so, avoided. The former course, though highly productive, is certain to turn biology into an engineering discipline. The latter holds the promise of making biology an even more fundamental science, one that, along with physics, probes and defines the nature of reality. This is a choice between a biology that solely does society's bidding and a biology that is society's teacher. PMID:15187180

  8. Teachers' Concerns About Biotechnology Education

    NASA Astrophysics Data System (ADS)

    Borgerding, Lisa A.; Sadler, Troy D.; Koroly, Mary Jo

    2013-04-01

    The impacts of biotechnology are found in nearly all sectors of society from health care and food products to environmental issues and energy sources. Despite the significance of biotechnology within the sciences, it has not become a prominent trend in science education. In this study, we seek to more fully identify biology teachers' concerns about biotechnology instruction and their reported practices. Consistent with the Stages of Concern framework as modified by Hord et al., we investigated teachers' awareness, informational, personal, management, consequences, collaboration, and refocusing concerns about biotechnology teaching by employing a qualitative design that allowed for the emergence of teachers' ideas. Twenty high school life science teachers attending a biotechnology institute were interviewed using an interview protocol specifically designed to target various Stages of Concern. Although the Stages of Concern framework guided the development of interview questions in order to target a wide range of concerns, data analysis employed a grounded theory approach wherein patterns emerged from teachers' own words and were constantly compared with each other to generate larger themes. Our results have potential to provide guidance for professional development providers and curriculum developers committed to supporting initial implementation of biotechnology education. Recommendations include supporting teacher development of biotechnology content knowledge; promoting strategies for obtaining, storing and managing biotechnology equipment and materials; providing opportunities for peer teaching as a means of building teacher confidence; and highlighting career opportunities in biotechnology and the intersections of biotechnology and everyday life.

    NASA Astrophysics Data System (ADS)

    Bennett, William D.; Park, Soonhye

    2011-02-01

    In teaching science, the beliefs of teachers may come into conflict and inhibit the implementation of reformed teaching practice. An experienced biology teacher, Mr. Hobbs, was found to have two different sets of epistemological beliefs while his classroom practice was predominantly teacher-centered. A case study was then performed in order to investigate the underlying issues that contributed to his classroom practice. Data sources included preliminary and follow-up interviews and classroom observations. Data analysis indicated that factors that prevented the epistemological conflict from reaching a resolution included Mr. Hobbs' beliefs about learning, contextual teaching factors, personal experiences as a student, and views of the nature of science. The findings from this case indicate that science teachers possess complex belief systems that are not immediately obvious to either the teacher or science teacher educators, and science teacher educators need to address teacher beliefs when they encourage teachers to implement reformed teaching practices.

    PubMed

    Kerwat, K; Becker, S; Wulf, H; Densow, D

    2010-08-01

    Biological weapons are weapons of mass destruction that use pathogens (bacteria, viruses) or the toxins produced by them to target living organisms or to contaminate non-living substances. In the past, biological warfare has been repeatedly used. Anthrax, plague and smallpox are regarded as the most dangerous biological weapons by various institutions. Nowadays it seems quite unlikely that biological warfare will be employed in any military campaigns. However, the possibility remains that biological weapons may be used in acts of bioterrorism. In addition all diseases caused by biological weapons may also occur naturally or as a result of a laboratory accident. Risk assessment with regard to biological danger often proves to be difficult. In this context, an early identification of a potentially dangerous situation through experts is essential to limit the degree of damage. PMID:20717866

    SciTech Connect

    Wiley, H S.

    2006-06-01

    The biology revolution over the last 50 years has been driven by the ascendancy of molecular biology. This was enthusiastically embraced by most biologists because it took us into increasingly familiar territory. It took mysterious processes, such as the replication of genetic material and assigned them parts that could be readily understood by the human mind. When we think of ''molecular machines'' as being the underlying basis of life, we are using a paradigm derived from everyday experience. However, the price that we paid was a relentless drive towards reductionism and the attendant balkanization of biology. Now along comes ''systems biology'' that promises us a solution to the problem of ''knowing more and more about less and less''. Unlike molecular biology, systems biology appears to be taking us into unfamiliar intellectual territory, such as statistics, mathematics and computer modeling. Not surprisingly, systems biology has met with widespread skepticism and resistance. Why do we need systems biology anyway and how does this new area of research promise to change the face of biology in the next couple of decades?

  9. Is synthetic biology mechanical biology?

    PubMed

    Holm, Sune

    2015-12-01

    A widespread and influential characterization of synthetic biology emphasizes that synthetic biology is the application of engineering principles to living systems. Furthermore, there is a strong tendency to express the engineering approach to organisms in terms of what seems to be an ontological claim: organisms are machines. In the paper I investigate the ontological and heuristic significance of the machine analogy in synthetic biology. I argue that the use of the machine analogy and the aim of producing rationally designed organisms does not necessarily imply a commitment to mechanical biology. The ideal of applying engineering principles to biology is best understood as expressing recognition of the machine-unlikeness of natural organisms and the limits of human cognition. The paper suggests an interpretation of the identification of organisms with machines in synthetic biology according to which it expresses a strategy for representing, understanding, and constructing living systems that are more machine-like than natural organisms.

  13. Science Partners for Teachers: Graduate Student-Teacher Partnerships

    NASA Astrophysics Data System (ADS)

    Rebull, L. M.; Munoz-Franco, L.

    1996-12-01

    Science Partners for Teachers is a group of scientists (mostly graduate students) in the physical and biological sciences at the University of Chicago which establishes one-on-one partnerships with Chicago-area K-12 school teachers. The goal is to have both partners benefit from the interaction. As scientists, we want to learn more about how to teach, how to develop lesson plans, and improve our ability to disseminate scientific knowledge (with an eye towards increasing our marketability for our future job searches). In exchange, we offer to be a resource for teachers looking to update their science curricula and to help incorporate and increase the use of computers, and the internet into the classroom. But most of all, we want to develop a relationship in which the scientist gains an inside look at teaching while the teacher gains an inside look at science and the way science is done. This model for scientist-teacher interaction is unique among the ones we have encountered as it involves a one-on-one partnering between adults (no K-12 students involved) and is specficially tailored to mesh well with an over-committed graduate student's schedule. This group was founded and continues to be run by several astrophysics graduate students who are looking for creative ways to help themselves and other grad students prepare for alternative careers related to education, preferably involving both research and outreach.

    The use of biological agents as controlled weapons of war is practical although uncertain. Three types of agents are feasible, including pathogenic organisms and biological pests, toxins, and synthetic hormones regulating plant growth. These agents may be chosen for selective effects varying from prolonged incipient illness to death of plants, man and domestic animals. For specific preventive and control measures required to combat these situations, there must be careful and detailed planning. The nucleus of such a program is available within the existing framework of public health activities. Additional research and expansion of established activities in time of attack are necessary parts of biological warfare defense. PMID:13059641

    Computer science has become ubiquitous in many areas of biological research, yet most high school and even college students are unaware of this. As a result, many college biology majors graduate without adequate computational skills for contemporary fields of biology. The absence of a computational element in secondary school biology classrooms is of growing concern to the computational biology community and biology teachers who would like to acquaint their students with updated approaches in the discipline. We present a first attempt to correct this absence by introducing a computational biology element to teach genetic evolution into advanced biology classes in two local high schools. Our primary goal was to show students how computation is used in biology and why a basic understanding of computation is necessary for research in many fields of biology. This curriculum is intended to be taught by a computational biologist who has worked with a high school advanced biology teacher to adapt the unit for his/her classroom, but a motivated high school teacher comfortable with mathematics and computing may be able to teach this alone. In this paper, we present our curriculum, which takes into consideration the constraints of the required curriculum, and discuss our experiences teaching it. We describe the successes and challenges we encountered while bringing this unit to high school students, discuss how we addressed these challenges, and make suggestions for future versions of this curriculum.We believe that our curriculum can be a valuable seed for further development of computational activities aimed at high school biology students. Further, our experiences may be of value to others teaching computational biology at this level. Our curriculum can be obtained at http://ecsite.cs.colorado.edu/?page_id=149#biology or by contacting the authors. PMID:22046118

  20. Advantages of a leveled commitment contracting protocol

    SciTech Connect

    Sandholm, T.W.; Lesser, V.R.

    1996-12-31

    In automated negotiation systems consisting of self-interested agents, contracts have traditionally been binding. Such contracts do not allow agents to efficiently accommodate future events. Game theory has proposed contingency contracts to solve this problem. Among computational agents, contingency contracts are often impractical due to large numbers of interdependent and unanticipated future events to be conditioned on, and because some events are not mutually observable. This paper proposes a leveled commitment contracting protocol that allows self-interested agents to efficiently accommodate future events by having the possibility of unilaterally decommitting from a contract based on local reasoning. A decommitment penalty is assigned to both agents in a contract: to be freed from the contract, an agent only pays this penalty to the other party. It is shown through formal analysis of several contracting settings that this leveled commitment feature in a contracting protocol increases Pareto efficiency of deals and can make contracts individually rational when no full commitment contract can. This advantage holds even if the agents decommit manipulatively.

    NASA Technical Reports Server (NTRS)

    Abbott, M. R.

    1984-01-01

    Within the framework of global biogeochemical cycles and ocean productivity, there are two areas that will be of particular interest to biological oceanography in the 1990s. The first is the mapping in space time of the biomass and productivity of phytoplankton in the world ocean. The second area is the coupling of biological and physical processes as it affects the distribution and growth rate of phytoplankton biomass. Certainly other areas will be of interest to biological oceanographers, but these two areas are amenable to observations from satellites. Temporal and spatial variability is a regular feature of marine ecosystems. The temporal and spatial variability of phytoplankton biomass and productivity which is ubiquitous at all time and space scales in the ocean must be characterized. Remote sensing from satellites addresses these problems with global observations of mesocale (2 to 20 days, 10 to 200 km) features over a long period of time.

  14. Finnish Cooperating Physics Teachers' Conceptions of Physics Teachers' Teacher Knowledge

    NASA Astrophysics Data System (ADS)

    Asikainen, Mervi A.; Hirvonen, Pekka E.

    2010-06-01

    This article examines Finnish cooperating physics teachers’ conceptions of teacher knowledge in physics. Six experienced teachers were interviewed. The data was analyzed to form categories concerning the basis of teacher knowledge, and the tradition of German Didaktik and Shulman’s theory of teacher knowledge were used in order to understand the results. The results show that the teachers strongly emphasize knowledge related to day-to-day teaching practice. In German Didaktik, this means knowledge of the best instructional methods, while in Shulman’s categorization it belongs to the category of representations, strategies, and methods. It was also found that the teachers appear to lack some of the essential key ideas of modern physics teacher education, such as a holistic view of instructional approaches.

    2004-10-01

    Understanding what teachers need to be more comfortable and confident in their profession is crucial to the future of effective teachers and scientific literacy in public schools. This study focuses on the experiences of Arizona biology teachers in teaching evolution, using a clinical model of stress to identify sources of pressure, the resulting stresses, and coping strategies they employ to alleviate these stresses. We conducted focus groups, one-on-one interviews, and written surveys with 15 biology teachers from the Phoenix area. On the basis of their responses, teachers were clustered into three categories: Conflicted, who struggle with their own beliefs and the possible impact of their teaching, Selective, who carefully avoid difficult topics and situations, and Scientists, who see no place for controversial social issues in their science classroom. Teachers from each group felt that they could be more effective in teaching evolution if they possessed the most up-to-date information about evolution and genomics, a safe space in which to reflect on the possible social and personal implications with their peers, and access to richer lesson plans for teaching evolution that include not only science but personal stories regarding how the lessons arose, and what problems and opportunities they created.

  7. Scaffolded biology.

    PubMed

    Minelli, Alessandro

    2016-09-01

    Descriptions and interpretations of the natural world are dominated by dichotomies such as organism vs. environment, nature vs. nurture, genetic vs. epigenetic, but in the last couple of decades strong dissatisfaction with those partitions has been repeatedly voiced and a number of alternative perspectives have been suggested, from perspectives such as Dawkins' extended phenotype, Turner's extended organism, Oyama's Developmental Systems Theory and Odling-Smee's niche construction theory. Last in time is the description of biological phenomena in terms of hybrids between an organism (scaffolded system) and a living or non-living scaffold, forming unit systems to study processes such as reproduction and development. As scaffold, eventually, we can define any resource used by the biological system, especially in development and reproduction, without incorporating it as happens in the case of resources fueling metabolism. Addressing biological systems as functionally scaffolded systems may help pointing to functional relationships that can impart temporal marking to the developmental process and thus explain its irreversibility; revisiting the boundary between development and metabolism and also regeneration phenomena, by suggesting a conceptual framework within which to investigate phenomena of regular hypermorphic regeneration such as characteristic of deer antlers; fixing a periodization of development in terms of the times at which a scaffolding relationship begins or is terminated; and promoting plant galls to legitimate study objects of developmental biology.

    Preston, R.J.

    1990-12-17

    The traveler attended the 1st International Conference on Biological Dosimetry in Madrid, Spain. This conference was organized to provide information to a general audience of biologists, physicists, radiotherapists, industrial hygiene personnel and individuals from related fields on the current ability of cytogenetic analysis to provide estimates of radiation dose in cases of occupational or environmental exposure. There is a growing interest in Spain in biological dosimetry because of the increased use of radiation sources for medical and occupational uses, and with this the anticipated and actual increase in numbers of overexposure. The traveler delivered the introductory lecture on Biological Dosimetry: Mechanistic Concepts'' that was intended to provide a framework by which the more applied lectures could be interpreted in a mechanistic way. A second component of the trip was to provide advice with regard to several recent cases of overexposure that had been or were being assessed by the Radiopathology and Radiotherapy Department of the Hospital General Gregorio Maranon'' in Madrid. The traveler had provided information on several of these, and had analyzed cells from some exposed or purportedly exposed individuals. The members of the biological dosimetry group were referred to individuals at REACTS at Oak Ridge Associated Universities for advice on follow-up treatment.

    NASA Astrophysics Data System (ADS)

    McGowan, J.

    2002-12-01

    Sverdrup's contribution to Biological Oceanography were more than merely substantial, they were of fundamental importance. His plan for the training of graduate students at Scripps did not recognize the traditional division of the basic disciplines into separate categories of physics, chemistry, biology and geology. He insisted that Oceanography was a multi-disciplinary subject and that all entering students should study all four subjects. Today this is not very unusual but it was in the early 50s when I took those courses. We biologists carried away from those courses an appreciation of the importance of both spatial and temporal scale. It was of clear relevance to problems of oceanic population and community biology. But there was still more to his biology. He is responsible for a very simple, but very elegant model of the regulation of oceanic primary productivity. The elements of this model are found today in the ten or so highly derivative models. He also published a map predicting global ocean productivity based on the ideas in the model plus some wonderfully intuitive thinking. This map does not differ strongly from those glorious false color ones being published today.

  9. Quality professional development for secondary science teachers

    NASA Astrophysics Data System (ADS)

    Mchazlett, Dwight Henry, Jr.

    This record of study (ROS) explores the perceptions of three high school biology teachers who implemented a form of the Japanese originated Lesson Study Professional Development (LS PD) model. Additionally, this ROS reports on the perceptions of the internal stakeholders with regard to the model's viability as a potential solution to a proposed problem of practice where there was a lack of quality professional development for secondary biology teachers. The audience of internal stakeholders includes district administrators, high school teachers, and science teachers from the elementary and middle school grade levels. Participants of this study collaboratively explored the problem of practice in the fall semester of 2015, then implemented the LS PD model in the spring semester. The participants completed three cycles of LS that focused on collaboratively designing research-based lessons, teaching the lessons with peer observations, revising and re-teaching the lessons with peer observations, and reflecting on the participants' growth experiences. Four research questions were addressed: (a) What are the perceptions of the participants in regard to their own professional growth as a result of participating in the LS initiative? (b) What improvements to the LS PD model might facilitate future implementation? and (c) What are the perceptions of the LS dissemination audience toward LS as a viable solution to a lack of quality PD for secondary biology teachers? Results of the study suggested that LS PD may be a viable solution to the proposed problem of practice where there is a lack of quality professional development for secondary biology teachers. Long-term implications posit that LS PD can be adapted and scaled up to benefit all content areas and grade levels.

  2. Biology Reflective Assessment Curriculum

    NASA Astrophysics Data System (ADS)

    Bayley, Cheryl Ann

    Often students and educators view assessments as an obligation and finality for a unit. In the current climate of high-stakes testing and accountability, the balance of time, resources and emphasis on students' scores related to assessment have been slanted considerably toward the summative side. This tension between assessment for accountability and assessment to inform teaching strains instruction and educators' ability to use that information to design learning opportunities that help students develop deeper conceptual understanding. A substantive body of research indicates that formative and reflective assessment can significantly improve student learning. Biology Reflective Assessment Curriculum (BRAC) examines support provided for high school science students through assessment practices. This investigation incorporates the usage of reflective assessments as a guiding practice for differentiated instruction and student choice. Reflective assessment is a metacognitive strategy that promotes self-monitoring and evaluation. The goals of the curriculum are to promote self-efficacy and conceptual understanding in students learning biology through developing their metacognitive awareness. BRAC was implemented in a high school biology classroom. Data from assessments, metacognitive surveys, self-efficacy surveys, reflective journals, student work, a culminating task and field notes were used to evaluate the effectiveness of the curriculum. The results suggest that students who develop their metacognitive skills developed a deeper conceptual understanding and improved feelings of self-efficacy when they were engaged in a reflective assessment unit embedded with student choice. BRAC is a tool for teachers to use assessments to assist students in becoming metacognitive and to guide student choice in learning opportunities.

    The advancing technology of our civilization on Earth affects our environment on a local, regional and global scale. Local effects can feed into larger scale effects because of positive feedbacks in our system. The ability to understand, quantify and predict the large scale and long-term effects of technology is truly mind boggling. The understanding of these effects, which is paramount to the quality of life on Earth, will depend upon the ability to interact with scientists from the biological, atmospheric, oceanographic and geological sciences and develop a common communication system and unified objectives.

  5. Exploring professional development experiences: Teachers' and facilitators' perceptions of Alabama Science in Motion

    NASA Astrophysics Data System (ADS)

    Burruss, Linda D.

    Teachers are often disillusioned because most of the professional development that they receive is inadequate (Chappuis, Chappuis, & Stiggins, 2009; Borko, 2004). With that in mind, reform efforts have placed attentive measures on the classroom and the way teachers can improve their instructional practices. The purpose of this study was to explore biology and chemistry teachers' and facilitators' perceptions of the Alabama Science in Motion (ASIM) professional development experience. Furthermore, the researcher conducted this study to determine whether or not ASIM had an impact on teachers' classroom instruction. The results of this study were significant in that it allows for policy makers to analyze the effect that the ASIM experience has on reforming and restructuring science education. A mixed-method research design was utilized. Data was gathered from teachers and facilitators via survey and focus group interview responses. The population consisted of teachers who were trained with ASIM modules and facilitators who trained teachers in the area of biology and chemistry. A statistical data analysis was employed using the Pearson r correlation coefficient test (Pearson r). The results of this study revealed that effective professional development has an impact on teachers' classroom instruction. Teachers and facilitators believed that ASIM made them more effective as a teacher and contributed strongly to their students' understanding of biology and chemistry. Moreover, teachers and facilitators believed that the ASIM modules assisted them in the implementation of the standards on the Alabama Course of Study.

    A semi-structured interview was used in Brazil to enquire into the 'notion of model' held by a total sample of 39 science teachers who were: employed in 'fundamental' (6-14 years) and 'medium' (15-17 years) schools; student science teachers currently doing their practicum; and university science teachers. Seven 'aspects' of their notions of a model were identified: the nature of a model, the use to which it can be put, the entities of which it consists, its relative uniqueness, the time span over which it is used, its status in the making of predictions, and the basis for the accreditation of its existence and use. Categories of meaning were identified for each of these aspects. The profiles of teachers' notions of 'model' in terms of the aspects and categories were complex, providing no support for the notion of 'Levels' in understanding. Teachers with degrees in chemistry or physics had different views about the notion of 'model' to those with degrees in biology or with teacher training certificates.

  13. Biological membranes

    Biological membranes allow life as we know it to exist. They form cells and enable separation between the inside and outside of an organism, controlling by means of their selective permeability which substances enter and leave. By allowing gradients of ions to be created across them, membranes also enable living organisms to generate energy. In addition, they control the flow of messages between cells by sending, receiving and processing information in the form of chemical and electrical signals. This essay summarizes the structure and function of membranes and the proteins within them, and describes their role in trafficking and transport, and their involvement in health and disease. Techniques for studying membranes are also discussed. PMID:26504250
