Explains how the "three D's" of ecology; diatoms, density, and diversity; can be used to generate student enthusiasm and spur investigations that can be conducted during student's own time. (PR)

Modeling is important in science and in science education. Computer-based modeling opens up new possibilities for learning science, particularly now that appropriate software is available. This article describes high school students' use of Model Builder software in high school classrooms. (PR)

Describes a high school pilot program to meet California's science curriculum guidelines to adopt a Scope, Sequence and Coordination (SS&C) approach. The SS&C curriculum offers four science subjects for each year of high school. Concrete, phenomenological, and descriptive topics are covered during the early years and theoretical and…

Introduces students to biological classification by having them classify music. (PR)

Indicates the difficulties for teacher educators in developing the content of courses because of changing conditions. Questions the context of the Concept Presentation assignment and asks how to progress in understanding the reflective processes involved in collaborative efforts inquiring into and improving professional practice. (Contains 30…

Describes remedial instruction activities as well as activity developmental strategies that utilize the results obtained from previous research on students' misconceptions related to photosynthesis to enhance 11th- and 12th-grade biology students' understanding of photosynthesis. (ZWH)

Explains how to use saliva instead of blood for classroom blood typing activities. Describes the protocol and equipment needed. (PR)

Describes the statistical test of chi-square analysis. Explains how this test can be used in biology instruction. Examples from blood typing are used. (PR)

Reports on the "Chemistry School" Project which explored the practicalities of using multimedia in secondary school science departments. Finds that although multimedia has many benefits for subject teachers, the problems of using it in everyday teaching are quite complex. Argues that simply training teachers to use information and…

This article discusses the rules science teachers need and how to implement these rules in the class. What should my science classroom rules be? Ideally, this question is asked prior to the teacher's entry to the classroom during their teacher training and revisited throughout their coursework preparation and student teaching. A science teacher…

The purpose of this study was to investigate the beliefs of six experienced high school science teachers about (1) what is successful science learning; (2) what are the purposes of laboratory in science teaching; and (3) how inquiry is implemented in the classroom. An interpretive multiple case study with an ethnographic orientation was used. The…

In this article, we describe the results of a study of the pedagogical content knowledge (PCK) of preservice chemistry teachers in the context of a postgraduate teacher education program. A group of preservice teachers (n = 12) took part in an experimental introductory course module about the use of particle models to help secondary school…

In an attempt to generate student enthusiasm on the subject of genetics, the author developed a Punnett square activity centered on the genetics of corn snakes to teach students about Mendelism and genetic diversity. As they began the activity, however, some unexpected twists occurred that allowed for investigation into corn snake anatomy and…

Project-based science (PBS) provides opportunities for students to engage in sustained inquiry in meaningful contexts. Science teachers want their students to attain scientific literacy for applications beyond the classroom. Unfortunately, many students view school, and especially school science, as disconnected from their lives and interests. PBS…

In this article, the author analyzes an inquiry-based project in order to examine students' efforts to build interpretations from evidence. This project fits within the Standards definition of scientific inquiry in several ways: (1) Students used previously learned biological concepts and principles to guide their inquiries; (2) Students relied on…
