One of the key agendas for the emerging field of disciplinary-based education research is the evaluation of the trajectory of disciplinary knowledge development from novice to expert. However, with the ongoing promotion of student-centered and collaborative undergraduate science classrooms, it is unknown how peer discourse during these exercises…

Informed understandings of nature of science and scientific inquiry are generally accepted goals of biology education. This article points out central features of scientific inquiry with relation to biology and the nature of science in general terms and focuses on the relationship of students' inquiry skills in biology and their beliefs on the…

There is no agreement about the robustness of intuitive representations of the circulatory system and their susceptibility to change by instruction. In this paper, we analyse to what extent students with varying degrees of biology instruction and different ages (High School Health Science and Social Science students and first and final year…

Interviews 9th and 10th grade students (n=13) who studied an ecology unit and analyzed tape-recorded data for changes in organization of knowledge, represented by ideational networks and the development of higher cognitive operations. Provides insights into how students developed knowledge schemata, ideational networks, and the capacity to express…

Discussed are problems revealed in student responses to a practical task which formed part of an advanced level examination. The frequencies with which some misconceptions about cell reproduction and genetics occurred are presented. The nature of these misconceptions is analyzed and their implications discussed. (CW)

Explores the knowledge development of Taiwanese 5th grade students (N=28) of biological reproduction. Proposes three stages of knowledge acquisition based on the results of the study. (Contains 17 references.) (DDR)

Reports research that examines children's models of seed. Explores the conceptions held by children (N=75) of germination and seed formation. Concludes that children hold a restricted meaning for the term 'seed'. (DDR)

The results of survey of secondary school biology students used to access misconceptions about cells are presented. A distinction between conceptions, misconceptions, and nonconceptions is drawn in terms of secondary school biology concepts. The resilience of misconceptions is discussed. (CW)

Reviews textbooks in use in the sixth-form classroom. Reports numerous examples of muddled facts, confusing explanations, and serious misconceptions. (DDR)

Investigated is the ability of high school pupils and university students to answer questions based on relationships within food webs using sound ecological principles. Research methods used and the results of this study are discussed. (CW)

Presented are the results of an analysis of the cognitive stages of tenth-grade pupils using a six-week unit on the respiratory system. The research design, instruments, and data analysis are discussed. A variety of cognitive levels was found and may be related to learning outcomes. (CW)

We examined the wildlife knowledge of primary (aged 4-12) schoolchildren. In particular, we examined the effects of children's age and gender, as well as the taxonomy and origin (indigenous versus exotic) of wildlife, on the degree of knowledge about different species. We used illustrated "flashcards" of mammals, birds and arthropods,…

Investigated are the alternative conceptions of the concept "animal" held by African youngsters. Three forms of thinking among the pupils are identified. An attempt is made to explain the possible origin of anthropocentric thinking among pupils. Urban and rural groups are compared. (CW)

Explores the rationale behind the importance of teaching young secondary school students how to look for correlation patterns. Describes two lessons that show how pupils can experience zero, positive, and negative correlation patterns between variables. Indicates the possible success of the Cognitive Acceleration through Science Education project.…

Describes a multiple-choice instrument that reliably and validly diagnoses secondary students' understanding of photosynthesis and respiration in plants. Highlights the consistency of students' misconceptions across secondary levels and indicates a high percentage of students have misconceptions regarding plant physiology. (CW)
