This paper summarizes the content and results of a workshop about the teaching of evolution presented to public middle school and high school science teachers by individuals involved both in university education and the professional development of teachers. The goals of the workshop were to: (1) provide teachers with knowledge and resources to…

The educational reform movement since the 1990s has led the secondary earth science curriculum in Taiwan into a stage of reshaping. The present study investigated secondary earth science teachers' perceptions on the Goals of Earth Science Education (GESE). The GESE should express the statements of philosophy and purpose toward which educators…

The present study deals with a school-based professional development trajectory for secondary science teachers, aiming at scaffolding teachers in open-inquiry teaching for the topic of water quality. Its design was based on the leading principle of "guiding by scaffolding". Seven experienced teachers participated in institutional…

Teaching ecological concepts in schools is important in promoting natural science and environmental education for young learners. Developing educational programs is difficult, however, because of complicated ecological processes operating on multiple levels, the unlimited nature of potential system interactions (given the openness of systems), and…

The study explored the influence of university-based teacher education courses on pre-service middle and high school teachers' experiences with multicultural themes in a secondary science alternative certification program. Eight participants (N = 8), six women and two men, volunteered to be a part of the study that took place over a period of four…

Teachers bring with them into the science classrooms their own gendered identities and their views and perceptions about how boys and girls learn and achieve in science. This paper tries to explore the way in which 14 Maltese science teachers use their own "personal practical knowledge" to identify their views about gender and science…

The growing awareness of serious difficulties in the learning of energy issues has produced a great deal of research, most of which is focused on specific conceptual aspects. In our opinion, the difficulties pointed out in the literature are interrelated and connected to other aspects (conceptual "as well as" procedural and axiological), which are…

This paper serves to review previously reported studies on students' misunderstandings about the energy conservation principle (the first law of thermodynamics). Generally, studies in literature highlighted students' misunderstandings about the energy conservation principle stem from preliminaries about energy concept in daily life. Since prior…

Several papers have been published on the use of a CD as a grating for undergraduate laboratories and/or for high school and college class demonstrations. Four years ago "The Physics Teacher" had a spectacular cover picture showing emission spectrum as viewed through a CD with no coating. That picture gave the impetus to develop a system that can…

This article is intended as a guide for teaching geomagnetism in a high school or university introductory physics class. Many students find this subject fascinating. Instructors, however, often have a difficult time introducing this topic at an elementary level. Suggestions will be made on how to accomplish this using three electricity and…

This article presents an engaging activity in which high school students use a dichotomous key to guide the creation and classification of model insects from recycled plastic lids and containers. Besides teaching the use of a dichotomous key and the effect of evolutionary descent upon groupings of organisms, this activity focuses on an…

This simple but effective laboratory exercise helps students understand the concept of protein domain function. They use foam beads, Styrofoam craft balls, and pipe cleaners to explore how domains within protein active sites interact to form a functional protein. The activity allows students to gain content mastery and an understanding of the…

This study explores the relationship between affective and cognitive variables in grade 9 chemistry students (n = 73). In particular, it explores how students' situational interest, their attitudes toward chemistry, and their chemistry-specific self-concept influence their understanding of chemistry concepts over the course of a school year. All…

The use of harmful organic solvents in classrooms has become a critical issue of concern in the field of chemistry education. This article describes a classroom activity at a high school in which an acrylic fabric was used as the extraction medium in the analysis of the detergent concentration in water instead of organic solvents. Dyes were used…

Storytelling is an age-old and powerful means of communication that can be used as an effective teaching strategy in the science classroom. This article describes the authors' experiences implementing the Storyline Approach, an inquiry-based teaching method first introduced by Kieran Egan (1986), in the context of teaching the concept of air…
