The science teacher in the modern high school acts as the designer and driver of the in-class practice. In this role, the teacher must broadly assess the effect of the practice on the student. This would rely on accurate self-knowledge of how they act in class and impact their students. In this study we explore these issues by comparing the…

The purpose of this study is to introduce an activity which has been designed in accordance with Science, Technology, Engineering, Mathematics (STEM) education within the scope of 5E learning model and to present the implementation steps of it. The activity plan is on the topics of Nerves, Hormones and Homeostasis in Human Physiology Unit in 11th…

We present results from the first year of a three-year extramurally funded project involving a partnership between an ethnically diverse urban high school and professional research botanists. The goals are to provide students exposure to real-world science, broaden interest in scientific fields of study, and increase floristic data and herbarium…

In-service teacher professional development has been used to improve teacher effectiveness. In Kentucky, the National Science Foundation funded a large professional development program called the Appalachian Math and Science Partnership (AMSP) to provide content-based professional development to teachers in rural schools. We show that students…

What is the effect on studies when integrating Web Assignment Checker (WAC) into science teaching? This article examines the change in students' attitudes to this question from the beginning of the course to its end, as compared with the attitudes of the teaching staff. The examiner's questionnaires, incorporating six aspects relating to students'…

The purpose of this paper is to carefully examine the evolution of students' theory building and modeling, critical components of scientific epistemologies, over a unit of study on sinking and floating in one third/fourth grade classroom. The study described in this paper follows in the tradition of Design Experiments (Brown 1992, Collins 1990)…

This article describes a research study concerning students' conceptions and reasonings about fluids and pressure in static situations. After a preliminary survey involving interviews and observations in class, some written questions were answered by various groups, totalling 428 Italian and French pupils in upper secondary school, 458 first-year…

The primary purpose was to investigate the efficacy of a full year of single-sex (SS) teaching of science. The secondary aims were to locate any differentiation by set and gender, and to relate these to more proximal variables. Participants were 13 year olds. Higher set girls gave evidence of clear benefits overall, and higher set boys also,…

Identifies misconceptions related to the fundamental characteristics of atoms and molecules held by twelfth-grade students. Data were obtained by administration of semistructured interviews to a stratified, random sample of 30 students. Fifty-two misconceptions were observed and reported. Some of the misconceptions identified parallel the…

Describes a study of the professional qualifications of high school physics teachers conducted by the American Institute of Physics (AIP). Concludes that high school physics teachers are better trained than they are given credit for, and that instances of utterly unqualified instructors are rare. (WRM)

The aim of this study was to detect primary students' conceptions about the origin and conveyance of electric current and about the connection of household electric appliances. In total, 383 students (aged 11-12) from the town of Volos, Greece, participated; 213 of them drawn from experimental classes and 170 from control groups. The results…

Describes: the chemical history of a pencil; a simple solar camera for measuring the sun's diameter; the experimental comparison of the thermal stability of metal carbonates; and the introduction of the concept of weight as a force to young children. A computer program listing on color mixing is also provided. (JN)

This paper reports design experiments on two Japanese elementary science lesson units in a sixth-grade classroom supported by computer support for collaborative learning (CSCL) technology as a collaborative reflection tool. We took different approaches in the experiments depending on their instructional goals. In the unit 'air and how things…

Reports a study analyzing the perceptions of 45 college science majors regarding their formal precollege science experiences. Results suggest that college science majors generally hold science in higher regard than do noncollegiate adults; preferred science teachers who were enthusiastic, knowledgeable, friendly, inspirational, and fun; and…

Changes in 70 teachers' confidence, attitudes and science understanding were tested before and after a major in-service programme. Attitudes were assessed using a 49-item Likert-scale test that probed attitudes to practical science teaching and in-service training. Multi-choice and open-ended questions measured understanding of electricity;…
