Biology content cognitive structure: From science student to science teacher

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. The results have implications for the well-known conjecture that teaching helps one better understand the content being taught.     

Towards teaching science for social responsibility: An examination of flaws in science,technology and society

In this paper we continue our search for a socially responsible science education by an examination of the trends in the Science, Technology and Society movement. These trends reflect differing ideological perspectives and result in courses which serve different ends. We identify two major flaws in the movement that inhibits the realization of a schooling in science dedicated to democracy. We propose skills necessary for citizens to participate in debate over issues surrounding the impact of science and technology on society and a teaching stategy to help develop them. Specializations: social responsibility and the curriculum, ideology and comparative science education.     

The effects of cognitive style and course content on classroom social behavior

This study of the effects of course content and cognitive style on students' classroom social behavior utilized 29 boys experiencing academic difficulties. After completing the Embedded Figures Test, each subject was assigned to either field-dependent (FD) or field-independent (FI) groups. Systematic observations of the two groups' classroom behaviors in French and mathematics classes were compared using ANOVA techniques. Results showed that the social behavior profiles of the two groups were the same on 18 behavioral categories. However, consistent with previous findings, FI subjects were more disruptive than FD subjects. Variance in social behavior was due principally to course content. The interactive effects of cognitive and task characteristics on social behavior are discussed within a cognitive-behavioral perspective.     

Influence of resequencing general science content on the science achievement,attitudes toward science,and interest in science of sixth grade students

This study was designed to determine the influence of resequencing general science content on sixth grade students' science achievement, attitudes toward science, and interest in science. Resequencing content was accomplished for experimental group students through revising the order of textbook chapters in a general science course, in order to clarify content structure and establish interrelationships among major concepts. The subjects were 203 sixth grade learners randomly assigned to the two treatment groups of resequenced content and nonresequenced content. The findings revealed that students for whom content structure was clarified through resequencing general science chapters exhibited significantly higher science achievement, significantly more positive attitudes toward science, and significantly greater interest in science than students for whom general science content was not resequenced.     

Development of a competency model and tailored assessment method for high school science teachers utilizing a flipped learning approach

Many professional development programs aim to improve student outcomes by enhancing teacher competencies. Effective evaluation of these programs requires a clear delineation of the competencies to be gained. A competency model was developed to evaluate the impact of a teacher professional program that aimed to improve teachers’ ability to effectively implement technologically engaged modules in a flipped classroom setting. Competencies were identified via participatory evaluation techniques and assessments were aligned to the competencies. The competency of teachers in the knowledge, skills, and abilities needed for creation and delivery of effective flipped lessons can be tracked using a radar graph to guide tailored professional development.

     

Development of a scale of cognitive demand for analysis of printed secondary science materials

Conclusion The Scale of Cognitive Demand, although of potentially daunting size, proved to be usable by teachers and useful to them. Validation of the Scale confirmed that the cognitive demand construct was meaningful and appropriate for distinguishing between the types of tasks encountered in printed Secondary Science materials. In the light of the data obtained from the trials by teachers, and the validation and reliability procedures, a modified form of the instrument has been prepared. Further research will be undertaken to establish the extent to which the modifications represent real improvements.     

Communication apprehension,social preference,and social behavior in a college environment

An investigation of high and low communication apprehensives in a college environment indicated that high communication apprehensives interact less with peer strangers, are less likely to accept a blind date, have fewer dates, are more likely to engage in exclusive dating, have close relationships with fewer faculty, are less satisfied with a university's advising system, and are less satisfied with the college environment. These results are examined within the context of the Berger‐Calabrese developmental theory of interpersonal communication and an extension of that theory is tentatively advanced.     

Uses of cognitive science to science education

The paper looks for common ground between cognitive science and science education starting from historical roots. Topics critically scrutinized are: representation of knowledge with applications of the schema and frame concept to physics education centering around the hierarchical structure of knowledge, the qualitative-quantitative distinction, the declarative-procedural distinction, and the semantic-episodic distinction; the uses of network versus production system representations, stressing the distinction between outward and inward representation which is often neglected; a short discussion of the likewise often forgotten index and reference issue.The paper has been presented to the ATEE Symposium on Implications of Cognitive Science for the Education of Science Teachers IPN (Kiel) 29.–30.08.1985.     

A flow-map method of representing cognitive structure based on respondents' narrative using science content

Increasing interest in science education research has focused on ways of representing cognitive structure in graphical and quantitative terms. A method is presented for displaying the sequential and multirelational ideation of scientific narrative elicited from respondents. The flow map provides a figural representation of the flow of information, the points in the flow where multirelational and recurrent linkages are made, and the time required to retrieve and express the information at major intervals in the sequence and in total. In keeping with constructivist models of information analysis, the elicitation of responses requires minimal intervention by the interviewer, and flow-map representation requires low inference for its construction, providing a convenient diagram of the sequential and multirelational thought patterns expressed by the respondent. The method is illustrated by analyzing interviews from students varying in academic achievement under two interview conditions that varied in emphasis on recall of multiple relationships. The illustrative data show that students of increasing academic ability produce flow maps of more complex patterns with more cross-relational linkages. These kinds of linkages, on the whole, increase with increased emphasis in the interview on recall of relationships.     

Motivation and social cognitive theory

This article discusses motivation from the perspective of Bandura’s social cognitive theory. Motivation refers to processes that instigate and sustain goal-directed activities. Motivational processes are personal/internal influences that lead to outcomes such as choice, effort, persistence, achievement, and environmental regulation. Motivation has been a prominent feature of social cognitive theory from the early modeling research to the current conception involving agency. The conceptual framework of reciprocal interactions is discussed, after which research is summarized on behavioral, environmental, and personal influences on motivation. Key internal motivational processes are goals and self-evaluations of progress, self-efficacy, social comparisons, values, outcome expectations, attributions, and self-regulation. Critical issues confronting the theory include diversity and culture, methodology, and long-term effects of interventions. The article concludes with additional recommendations for future research on contexts, conceptual clarity, and technology.     

Science education research and cognitive science

Cognitive science has the potential for offering explanatory models for many of the findings of empirical research in science education. In this paper, I use recent editions of international journals of science education to produce a categorisation of types of science education research, and what possible contributions each might make to cognitive science or the potential of results from cognitive science for enriching the science education research accounts. In a short, final section, the relationship of our own cognitive work to cognitive science is explored.

Integrating moral and social development within middle school social studies: a social cognitive domain approach

Eleven teachers and 254 urban middle-school students comprised the sample of this study examining the social and moral development outcomes of the integration of social cognitive domain theory within regular classroom instruction. Participating teachers were trained to construct and implement history lessons that stimulated students’ moral reasoning and conceptions of societal convention. In comparison with baselines and controls, teachers reduced didactic instruction and increased the proportion of class time devoted to small group discussions. Student engagement in transactive discourse significantly increased in participating classes with significantly greater post-test levels of moral reasoning, concepts of social convention, and cross-domain coordination. Student production of operational versus representational transacts through transactive discussion was associated with growth in moral and societal concepts. Teachers continued teaching lessons constructed in the project a year after the research ended.     

Curriculum-based teacher professional development in middle school science: A comparison of training focused on cognitive science principles versus content knowledge

This study investigates, through a cluster-randomized trial, the effectiveness of two approaches to increasing middle school students’ science learning using a traditional science curriculum. Ninety schools were randomly assigned into one of three arms: (a) a treatment arm in which the textbook curriculum was modified based on four principles of cognitive science coupled with teacher professional development (PD), (b) a second treatment arm in which teachers received PD designed to improve their knowledge of the science content, and (c) a business-as-usual control group. The PD was able to change teacher practice but barely improved teacher knowledge. No significant boost in student achievement was observed, except in a few instances, where there were some promising findings. Exploratory analyses were conducted to examine what makes the interventions more effective. Implications for future research were discussed.
