This qualitative study analyzed grade 12 biology students' answers to written extended-response questions that describe hypothetical scenarios of animals' evolution. We investigated whether these type of questions are suitable for students (n = 24) to express a meaningful understanding of evolutionary theory. Meaningful understanding is comprised…

The purpose of this qualitative study was to identify and explain the origins of physics and chemistry teacher candidates' beliefs about teaching about ethics through socioscientific issues (SSI). This study utilized a series of in-depth interviews, while the participants (n = 12) were enrolled in a 9-month teacher education program at an urban…

Reports on the analysis of science curricula carried out across Canada within the framework of the Second International Science Study by: (1) describing the background to the study and the research methodology employed; (2) showing how data were organized; and (3) discussing meanings derived from the data analysis. (JN)

Explores preservice teachers' (n=151) metaphors of teaching and learning and examines some components of student teachers' own intuitions. Concludes that metaphors communicate a richness of meaning that conveys elements of mood, control, roles, attitudes, and beliefs as they apply to teaching and learning and are grounded on more deeply rooted…

Reports on an analysis of secondary school physics teaching with respect to three aspects of curriculum. Indicates that limited but significant relationships exist among intentions, translations, and achievement in the teaching of physics in Canadian secondary schools. (TW)

Reports a qualitative analysis of classroom discourse in which use of questions by science teachers is assessed in terms of arguments to establish scientific knowledge claims. Questions are analyzed not for form/frequency but for their function in developing arguments that establish claims rationally. (Author/JN)

Reported the development and validation of an integrated model of performance on chemical concept-volumetric analysis. Model was tested on 265 chemistry students in eight schools.Results indicated that for subjects using algorithms without understanding, performance on volumetric analysis problems was not influenced by proportional reasoning…

Investigated attitudes and learning of students (N=816) in 31 museum tours. Concluded that students (grades 5-7) had greater cognitive learning when participating in structured tours (led by museum docent). However, more positive attitudes were found when students participated in less structured tours lead by their classroom teacher. (JN)

Presents a logical analysis of three vector concepts (position, displacement, velocity) in terms of their constituent characteristics and shows how they can be used to structure an empirical investigation into students' prior knowledge about these characteristics. Reports results of students' (N=20) conceptions about the vector characteristics…

Reports on a study of Canadian upper secondary science students' achievement of the concept of proportion. Results indicated that, in classes where the proportion content was emphasized by the teachers, higher achievement was demonstrated. (TW)

Presents an action-oriented research account of higher-order cognitive skills (HOCS)-oriented teaching of organic chemistry to freshman and sophomore science majors in small and large classes at a relatively small and large university respectively. Finds that inquiry-oriented class discussions, students' active involvement in the learning process,…

Examined beliefs and principles of one science teacher using the Repertory Grid Technique. The technique is illustrated thoroughly with ample interview segments provided. The significance of the study is argued within the framework of curriculum and instructional innovation and implementation. (Author/JN)

Outlines arguments for action research approaches to the implementation of STS education. Presents six teachers' initial views and changing perceptions throughout the duration of an action research project in terms of four categories: nature of STS education, development of curriculum materials, personal/professional development, and collaborative…

Field tests of the Science Laboratory Environment Inventory (SLEI) with (n=5,447) high school and college students in six countries furnished evidence that science laboratory classes are dominated by closed-ended activities and that females held generally more favorable perceptions than males. Describes the development and validation of SLEI.…

Grade 10 students (n=1,564) perceptions of classroom practices and activities, as well as their attitudes toward science teaching and school science, were assessed in British Columbia. Major findings were that students do not appreciate the most prevailing contemporary practices in science classes and that they prefer science teaching and learning…
