The development of a unit of study and related teacher's guide on structure and function of living things for use with slow learners at the secondary levelMichel, Donald E. January 1973 (has links)
The goal of the present research study was to develop, test, and evaluate a unit of study covering the topic of structure and function of living things with special emphasis on the human body. The unit of study was designed for slow learners at the secondary school level. A teacher's guide integrated with student materials was also developed. Relevancy and appropriateness of subject matter and teaching approaches for slow learners were considered in the development of the unit of study. A group-paced teacher-directed approach was selected as the basic method of instruction. The effectiveness of the unit of study was measured, by determining the significance of difference between pretest and posttest scores of the students involved in the testing program. The effectiveness of the unit of study was also assessed by means of student and teacher responses on an evaluation instrument.

Understanding the teaching of biology at A levelFrancis Black, Alison January 2005 (has links)
This research focuses on uncovering, from the perspectives of practitioners themselves, the practical knowledge and understanding that shapes three teachers' successful teaching of biology at A level. Adopting a case study approach, it investigates the ways in which these biology teachers characterise their successful teaching of the subject at A level. It also explores the subject matter knowledge and understanding that shapes and accounts for these characterisations without making assumptions about the nature of this knowledge. Data are collected through the non-participant observation of a connected series of the teachers' A level biology lessons as well as informant-style interviewing following the observed lessons. The findings suggest that the main aim of the teachers' successful teaching of biology at A level is to ensure their students achieve examination success. In light of this, their teaching can be characterised in terms of three central features. First, they believe that to achieve this aim their students only need to know the substantive dimension of biological knowledge - they do not consider knowing the syntactic dimension to be a prerequisite to examination success. Second, they believe that their students need to conceptualise this substantive biological knowledge in several patterned ways. Third, they believe that the best way to encourage their students to develop and retain these specific conceptualisations is by adopting carefully controlled and highly structured teacher-centred pedagogical strategies. The teachers' characterisations appear to be shaped and accounted for by specific conceptions of biology which provide an overall structure to substantive biological knowledge - a structure that is determined by various guiding principles. This research provides a first attempt to map out the practical knowledge and understanding that shapes the successful teaching of biology at A level from the perspectives of teachers themselves. The ways in which these teachers characterise their teaching differ significantly from the ways in which such teaching is described in most of the extant literature in science education on teaching and learning. This study suggests that the teachers, far from lacking in knowledge, skills and understanding, are highly skilled practitioners who respond to the local and national contexts in which they work and, taking account of these, shape their subject matter teaching accordingly such that their main aim - student examination success - is achievable. This study highlights the discrepancy between academic writing in science education on practice and practice itself. The thesis ends with a consideration of the implications of the study for the research agenda in science education, the school science curriculum and the curriculum for teacher education in both preparing and supporting the professional development of science teachers.

Testing the effectiveness of problem-based learning through problem generation and problem solving with high school biology studentsGuerrera, Claudia P. January 1995 (has links)
The purpose of this study was to examine the effectiveness of problem-based learning (PBL) as an alternative teaching method in biology. Eighty-one, ninth grade biology students worked collaboratively in groups, of 2 or 3, to generate a fictitious patient case, which was then exchanged, for other students to solve. This process was repeated on two occasions. Data from pre/post questionnaires and groups' verbal and written protocols were analyzed. Results showed that certain cognitive processes strengthened over time. Significant improvements were also noted in the quality and content of students' written scenarios and solutions, and in students' interest in working collaboratively. Overall, this study confirms that PBL has numerous benefits and holds great potential as an instructional method in biology.

Wanopvattings oor fotosintese by standerd nege biologieleerlingeSmit, G. J. 02 April 2014 (has links)
M.Ed. (Didactics - Natural Sciences) / The specific aim of this study is to identify misconceptions about· photosynthesis among Standard 9 pupils. To identify the possible misconceptions which may occur about photosynthesis, the writer made an empirical study using questionnaires which comprised of definitions, multiple choice and descriptive questions. The possible misconceptions and the possible nature of the misconceptions about photosynthesis were identified after the completion of the questionnaire. Comparisons were then made to see whether there was a correlation between the relevant study and other studies in the literature available.

Indiana high school biology teachers and evolutionary theory : acceptance and understandingRutledge, Michael L. January 1996 (has links)
The purpose of this dissertation was to explore the status of and relationships among the variables of teacher acceptance of evolutionary theory, teacher understanding of evolutionary theory, and teacher understanding of the nature of science among Indiana public high school biology teachers. The relationships between these variables and the emphasis evolution receives in the classroom and teacher academic variables were investigated. Teacher knowledge structure of the concept of evolution was also explored.To answer the questions and hypotheses delineated in the study, a 68-item questionnaire and concept mapping activity was administered to the population of 989 teachers. The response rate was 53%.The teachers exhibited only a moderate level of acceptance and a marginal level of understanding of evolutionary theory. Teacher understanding of the nature of science was moderately high. Evolution played only a minor role in the curriculum. While the teachers had completed considerable course work in biology, the vast majority lacked specific course work in evolution and the nature of science.The data revealed a significant relationship between teacher acceptance and teacher understanding of evolutionary theory and between teacher acceptance of evolutionary theory and teacher understanding of the nature of science. The data also revealed significant associations between teacher allocation of instructional time to evolution and teacher level of acceptance of evolutionary theory, teacher level of understanding of evolutionary theory, teacher level of understanding of the nature of science, and teacher completion of a course in evolution. Additionally, the data revealed significant associations between teacher level of understanding of evolutionary theory and teacher completion of a course in evolution and teacher academic background in biology. Significant associations were revealed between teacher level of acceptance of evolutionary theory and both teacher completion of a course in evolution and teacher completion of a course in the nature of science.A significant amount of the variance in teacher acceptance of evolutionary theory was explained by the other variables delineated. The concept mapping activity revealed that teacher acceptance and understanding of evolutionary theory was reflected in teacher knowledge structure of evolution and that teachers' knowledge structures were characterized by an unsophisticated organizational framework. / Department of Biology

Integrating Concepts in Modern Molecular Biology into a High School Biology CurriculumParker, Timothy P. 08 1900 (has links)
More so than any other science in the past several decades, Biology has seen an explosion of new information and monumental discoveries that have had a profound impact on much more than the science itself. Much of this has occurred at the molecular level. Many of these modern concepts, ideas, and technologies, as well as their historical context, can be easily understood and appreciated at the high school level. Moreover, it is argued here that the integration of this is critical for making biology relevant as a modern science. A contemporary high school biology curriculum should adequately reflect this newly acquired knowledge and how it has already has already begun to revolutionize medicine, agriculture, and the study of biology itself.
This curriculum provides teachers with a detailed framework for integrating molecular biology into a high school biology curriculum. It is not intended to represent the curriculum for an entire academic year, but should be considered a significant component. In addition to examining key concepts and discoveries, it examines modern molecular techniques, their applications, and their relevance to science and beyond. It also provides several recommended labs and helpful protocols.
