This study reports on teaching practices in science classrooms of Indonesian lower secondary schools in rural areas. Using six schools from three districts in the province of Kalimantan Selatan as the sample, this study found that most teaching practices in science classrooms in rural schools were teacher-centred with students copying notes.…

This research aims to devise a set of computer-based tools to meet the diverse needs of learners for comprehending a science learning unit, namely work. A model of computer-based tools on the learning unit for developing procedural knowledge for solving work problems was developed together with a set of teacher customization and collaboration…

Recent science and teacher education reports continue to stress the need for radical changes in the way teachers are prepared to teach science to diverse learners. In response, a three-year intervention project was developed to help teachers in culturally diverse schools transform their science teaching practices using learning technologies. Many…

Because cell biology has rapidly increased in breadth and depth, instructors are challenged not only to provide undergraduate science students with a strong, up-to-date foundation of knowledge, but also to engage them in the scientific process. To these ends, revision of the Cell Biology Lab course at the University of Wisconsin-La Crosse was…

We carried out an experiment to determine whether student learning gains in a large, traditionally taught, upper-division lecture course in developmental biology could be increased by partially changing to a more interactive classroom format. In two successive semesters, we presented the same course syllabus using different teaching styles: in…

Student achievement, attitude, and instructional efficiency were determined for hands-on and for live and videotape demonstration laboratories for nonscience majors. Each of 3 laboratory sections experienced 3 different teaching methods for one 4-wk unit. No significant difference in achievement was found among the laboratory methods. An attitude…

A science content course in food chemistry was offered as a 4-day summer workshop from 1999 to 2001 to 4th grade school teachers in the Seattle School District. The objectives of the workshop were to increase the teachers' knowledge of food science, to perform simple experiments that could be used in the 4th grade classroom, and to help the…

This project explores the effectiveness of learner-centered education (LCE) principles and practices on student learning and attitudes in an online interactive introductory astronomy course for non-science majors by comparing a high-quality Internet-delivered course with a high-quality on-campus course, both of which are based on the principles of…

This study investigated the validation of Turkish version of the Teacher Communication Behavior Questionnaire (TCBQ) in a cross-study of elementary school science classrooms. The effects of gender and grade level on students' perceptions of their teachers' behaviors were also examined. Questionnaire includes five scales namely challenging,…

This study explored the role of student characteristics in studying micro teaching-learning environments. The overarching hypothesis is that teachers teach differently to micro environments in their classrooms. This study is the first of a series exploring the following four questions: (1) What student profiles are identified at the beginning of a…

In this study, instructional activities in science classrooms are examined in order to collect evidence to account for the strengths and weaknesses of Hong Kong students in scientific literacy as reported in the PISA 2000 project. The study consists of a questionnaire survey on the perceptions of classroom climate of science lessons of 17,616…

In July, 2005, the European Institute of Chemistry and Biology at the campus of the University of Bordeaux, France, hosted a focused week of seminars, workshops, and discussions around the theme of "teaching signal transduction." The purpose of the summer school was to offer both junior and senior university instructors a chance to…

Research suggests that undergraduate students learn more from lab experiences that involve longer-term projects. We have developed a one-semester laboratory sequence aimed at sophomore-level undergraduates. In designing this curriculum, we focused on several educational objectives: 1) giving students a feel for the scientific research process, 2)…

We are developing a new activity-based unit on global warming and the environment as part of the "Explorations in Physics Curriculum." We describe the current status of this unit, which focuses on helping students understand the greenhouse effect and its relationship to global warming. We outline several problems encountered in testing the unit…

This article examines the role of friends in girls' and boys' advanced course taking and explores whether friends' characteristics are particularly important for girls' math and science attainment. With the use of data from Adolescent Health and Academic Achievement and the National Longitudinal Study of Adolescent Heath, the results indicate that…
