Based on the premise that multiple choice tests can be used as diagnostic tools for teachers in identifying and remedying student misconceptions, this study focused on the development of an instrument for diagnosing secondary students' understanding of photosynthesis and respiration. Information is presented on: (1) procedures of development of…

Discusses alternative assessment and how it helps teaching practices. Defines embedded assessment as an ongoing, cyclical process in which teachers gather information on students' understanding and reasoning about content knowledge, then make sense and use the information to make adjustments for teaching in response to students' learning needs.…

Comments on the study reported by Lawson, Karplus, and Adi (1978) which indicated that formal schemata and propositional logic are not part of the same structured unity of mental operations proposed by Piaget. (HM)

Most school curricula include the study of health as a separate subject or as part of science. Despite this, students often leave school without a clear understanding of many health concepts. This study investigated a group of grade eight and nine students' knowledge of personal health and physical fitness concepts and its relation to locus of…

In a response to lower test scores in science and mathematics in Australia, the Western Australian Institute of Technology conducted a study to identify high quality science and mathematics teachers in Western Australian schools. This paper describes the teaching practices of one male and one female teacher of biology from two different schools.…

The presentation of gas properties in terms of the qualitative-quantitative mode and gas law sequence is examined by analysis of 14 chemistry textbooks used in Australia and on questionnaires concerning teaching approaches by 104 teachers. Findings indicate that teaching involves minimal use of qualitative relationships of the gas laws and…

Despite a strong tradition of research and practical applications involving perceptions of psychosocial environment in elementary and secondary science classes, surprisingly little analogous work has been conducted at the tertiary level. Consequently, in order to facilitate such work, a new instrument called the College and University Classroom…

Recent research literature has highlighted the interest of both teachers and researchers in using analogies to aid students' conceptual understanding. This appears to be especially relevant in secondary chemistry education due to the many abstract concepts that are included in the curricula. This paper reviews recent literature and considers…

A laboratory exercise using a gerbil is described for use in the high school biology class and in accordance with the National Science Teachers Association guidelines. The authors cite references that deal with current awareness of the moral status concerning animals. The exercise includes measurement and calculations. (SA)

This case study describes 1 teacher's implementation of a modified version of Glynn's Teaching-with-Analogies model with a grade-10 optics class on refraction of light. (PR)

Discussed is an approach to learning in which students are given the opportunity to discuss and rationalize the conflict between the students' existing misconceptions and the phenomenon to be studied. Curriculum materials for a unit on acids and bases were developed using this strategy. (KR)

Examines the work of one teacher who taught the topic of sound to grade 8 students over a period of three weeks. Presents the findings of the study as five assertions using interpretive research methodology. Concludes with a discussion on the current reforms, which support that the integration of teaching with assessment leads to improvement of…

The purpose of this paper was to investigate students' views on models and modelling in science as well as the role that models play in learning, using a theoretical framework of models in learning. Students' views on models in science were investigated using a pencil-and-paper questionnaire given to 275 students from Grade 8 (13 years old) to…

Large-scale assessments of student achievement provide a window into the broadly defined concepts of literacy and generate information about levels and types of student achievement in relation to some of the correlates of learning, such as student background, attitudes, and perceptions, and perhaps school and home characteristics. This paper…

This research used semistructured interviews to investigate students' (n=32) understanding of electrochemistry following a 7-9 week course of instruction. Three misconceptions were identified and incorporated with five previously reported into an alternative framework about electric current involving drifting electrons. Also noted was the tendency…
