Notes that women in the United States are underrepresented in science, mathematics, and engineering educational programs and careers. Uses longitudinal survey responses of 320 students to assess the ways in which their social relationships and experiences affect their involvement in science and technology. Frames issues in terms of identity…

Evolution by natural selection provides the conceptual framework upon which much of modern biology is based: therefore understanding core ideas about biological evolution is an essential part of scientific literacy. Nonetheless, research repeatedly shows that high school and college students have difficulties understanding the notion of natural…

Science teachers ask questions to assess students' cognitive abilities and to promote student motivation in learning. Cognitive questions are usually divided into low-order and high-order types. According to the conceptual change model of learning, teachers can also use questions to facilitate the construction of knowledge by students. These…

Salters-Nuffield Advanced Biology is a new advanced level biology course, piloted from September 2002 in England with around 1200 students. This paper discusses the reasons for developing a new advanced biology course at this time, the philosophy of the project and how the materials are being written and the specification devised. The aim of the…

This paper focuses on the use of multimedia-based predict--observe--explain (POE) tasks to facilitate small group learning conversations. Although the tasks were given to pairs of students as a diagnostic tool to elicit their pre-instructional physics conceptions, they also provided a peer learning opportunity for students. The study adopted a…

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…
