Understanding how teaching affects students' attitudes and beliefs is notoriously difficult, specifically in a quickly evolving and societally relevant field such as genetics. The aim of this survey study is to capitalize our previous research and examine how teaching relates to Finnish secondary school students' liking of, self-concept in and…

Drawing on cognitive theories, this study intends to investigate the effects of explicit visual cues which have been proposed as a critical factor in facilitating understanding of biological images. Three diagrams from Taiwanese textbooks with implicit visual cues, involving the concepts of biological classification systems, fish taxonomy, and…

Problem-solving has been one of the major strands in science education research. But much of the problem-solving research has been conducted on discipline-based contexts; little research has been done on how students, especially individuals, solve interdisciplinary problems. To understand how individuals reason about interdisciplinary problems, we…

There is growing evidence that targeted instruction can improve diagram comprehension, yet one of the skills identified in the diagram comprehension literature--coordinating multiple representations--has rarely been directly taught to students and tested as a classroom intervention. We created a Coordinating Multiple Representation (CMR)…

This article reports on a classroom study of a unit on New Zealand birds that focused on adaptation and conservation in a Year 7 class. The unit used a "context as social circumstances" model. The researchers observed the nine lessons and interviewed students, the classroom teacher, and three other teachers who had taught the same unit.…

In South Africa, foundation programmes are a well-established alternative access route to tertiary science study for educationally disadvantaged students. Student access to, and performance in, one such foundation programme has been researched by the authors seeking opportunities to improve student retention. The biology module in particular has…

In this paper we explore the relationship between learning gains, measured through pre-assessment and post-assessment, and engagement in scientific argumentation. In order to do so, this paper examines group discourse and individual learning during the implementation of NASA Classroom of the Future's BioBLAST![R] (BB) software program in a high…

The purpose of this study was to examine how prior knowledge of cellular transport influenced how high school students in the USA viewed and interpreted graphic representations of this topic. The participants were Advanced Placement Biology students (n = 65); each participant had previously taken a biology course in high school. After assessing…

This paper presents a case study of a teaching intervention designed to enrich Year 2 students' theory of biology through the introduction of causal mechanisms of inheritance such as the gene and DNA. The researchers worked collaboratively with the classroom teacher to design the intervention based on the students' prior knowledge of living things…

Reports on the assessment of student background knowledge along a continuum of language dependency using a set of three probes. Examines improved student performance in each of the respective assessments on the extent to which a sound natural history background facilitated meaningful learning relative to English as Second Language (ESL)…

Uses an instrument designed to identify misconceptions in biology to reveal that novice biology teachers hold a number of conceptual errors which are also prevalent among secondary science students. Contains 44 references. (DDR)

This paper reports on a qualitative case study investigation of the knowledge and use of learning strategies by 16 students in a final year high school biology class to expand their conscious knowledge of learning. Students were provided with opportunities to engage in purposeful inquiry into the biological, social and ethical aspects of cancer. A…

Describes trends in students' explanations of biological change in organisms. Student responses to questions on how graphically depicted phenomena occur were analyzed and most students were unable to offer causal explanations. (Contains 27 references.) (DDR)

Speculates about reasons for the lack of use of concept mapping as an instructional strategy. Concludes that the two main barriers to its extensive adoption are the epistemological beliefs of classroom teachers and the underlying philosophy of the curriculum. (Contains 45 references.) (DDR)

Argues that the life sciences offer potential for practical work to be undertaken outside the classroom. Explores a rationale for such work and draws on reported studies from a number of countries. Contains 44 references. (DDR)
