Students of biology must learn the scientific method for generating information in the field. Concurrently, they should learn how information is reported and accessed. We developed a progressive set of exercises for the undergraduate introductory biology laboratory that combine these objectives. Pre- and postassessments of approximately 100…

The first challenge in designing and teaching any course is to decide what to teach. At most colleges and universities, the process of selecting course content is an extremely local enterprise. Sometimes the decisions are made by a small group of faculty members, but most often they are made by a single professor with the responsibility of…

This study investigated the effectiveness of conceptual change texts oriented instruction accompanied by demonstrations in small groups on students' ecology achievement and attitude towards biology. 78 ninth grade students in a public high school participated in this study. While the control group was taught with the traditional method, the…

This qualitative case study examined web-based portfolio development in the service of supporting reflective thinking and learning within the innovative context of Professional Development Schools. Specifically, this study investigated the nature of the evidence-based philosophies developed by prospective teachers as the central part of the…

Lesotho and Turkey are two developing countries, both relatively deficient in educational resources--one in Southern Africa, and the other straddling the continents of Europe and Asia in the Middle East. This study reports and compares the priorities and responses of (a) 172 Turkish science teachers, lecturers and students, and (b) 171 Lesotho…

This paper reports the development of attitudes to science and science teaching scales for primary teachers. The investigation is part of a project intended to improve pupil achievement in science in 16 English city schools. The baseline performance of the attitude scales is reported with 76 teachers, half of whom formed a control group. The…

We examine the science and pedagogy behind a historical approach to the professional development of pre-college science (primarily biology) teachers. Our intention is to reach professional scientists, who, as a group, are uniquely qualified to provide experience and insights essential to this approach. The underlying research for this article has…

This article describes the teaching method used by Timothy Hearn, a chemistry teacher at Frederick Douglass Academy in Harlem. Timothy Hearn uses a stern behavior-based classroom management system to keep his students' attention. While teaching, Hearn tracks each students' behavior on a clipboard that he always carries. He determines each…

Written by a prominent array of scholars and practitioners, this book elucidates the complexities, contradictions, and confusion surrounding adolescence in American culture and education. For too long, harmful public myths and lies have portrayed teenagers as a principal cause of our nation's social ills. Similar unfair charges have been lodged…

This study qualitatively investigates the taboo and "noa" topics of Science-Technology-Society (STS) taught in two local cultures. Taboos are beliefs that constrain behavior by making those behaviors perceived as threatening by the members of the social group forbidden and improper for discussion. "Noa" is the Polynesian word…

The National Student Research Center (NSRC) is dedicated to promoting student research and the use of the scientific method in all subject areas across the curriculum, especially science and mathematics. The NSRC facilitates the implementation of a nationally recognized, innovative, and highly effective approach to instruction called the Student…

This paper discusses teaching science to language minority students and describes work with linguistic minority children and their teachers. A key goal of this work is to create scientific sense-making communities in the classroom that parallel science as it is practiced in the world. Following a critique of current practice in science education,…

The purpose of this study was to give voice to students' perceptions in two science classrooms taught by two white teachers in an urban multicultural middle-level school situated in the American Deep South. Student participants were 35 students of different ethnicities in grades 7 and 8. The theoretical reference used is social contextual, a…

This manual has been prepared by Ohio educators and the Ohio Department of Education to assist teachers in preparing their students for success in the Ohio Fourth-grade Proficiency Tests in Writing, Reading, Mathematics, Citizenship, and Science. Actual student responses to the April 1994 field test items are used in this manual to illustrate…

This project originated with the desire to offer general biology students a laboratory experience which emphasizes scientific thinking rather than a review of lecture content. To create investigative laboratories without many of the practical problems of their implementation, this project uses a combination of "methods modules" for…
