One of the goals of science education is to provide students with the ability to construct arguments--reasoning and thinking critically in a scientific context. Over the years, many studies have been conducted on constructing arguments in science teaching, but only few of them have dealt with studying argumentation in the laboratory. Our research…

Chemical bonding is one of the key and basic concepts in chemistry. The learning of many of the concepts taught in chemistry, in both secondary schools as well as in the colleges, is dependent upon understanding fundamental ideas related to chemical bonding. Nevertheless, the concept is perceived by teachers, as well as by learners, as difficult,…

The traditional pedagogical approach for teaching chemical bonding is often overly simplistic and not aligned with the most up-to-date scientific models. As a result, high-school students around the world lack fundamental understanding of chemical bonding. In order to improve students' understanding of this concept, it was essential to propose a…

Argumentation is believed to be a significant component of scientific inquiry: introducing these skills into laboratory work may be regarded as a goal for developing practical work in school science. This study explored the impact on the quality of argumentation among 12- to 13-year-old students undertaking three different designs of…

The study describes the process of adopting new curriculum materials, which had been developed in the PARSEL project in several European countries, into the local educational science classroom of another country. The goal of the PARSEL project was to raise the popularity and relevance of science teaching by enhancing students scientific and…

The focus of this collaborative research project of King's College London, and the Weizmann Institute, Israel is on investigating the ways in which teachers can demonstrate accomplished teaching in a specific domain of science and on the teacher learning that is generated through continuing professional development (CPD) programmes that lead…

In this study our goal was to better understand the development of chemistry teachers who are involved in a continuous professional development (CPD) programme, focusing on using the inquiry approach in the chemistry classroom-laboratory, followed by protocols assembled in a portfolio that can be used to demonstrate evidence-based practice in…

The laboratory has been given a central and distinctive role in science education, and science educators have suggested that rich benefits in learning accrue from using laboratory activities. Twenty years have been elapsed since we published a frequently cited, critical review of the research on the school science laboratory (Hofstein & Lunetta,…

This paper set emerged from an international symposium that aimed to shed light on issues associated with the enactment of inquiry both as means (i.e., inquiry as an instructional approach) and as ends (i.e., inquiry as a learning outcome) in precollege science classrooms. The symposium contributors were charged with providing perspectives from…

In this paper, we present the development and implementation over the period of more than 15 years of learning materials focusing on industrial chemistry as the main theme. The work was conducted in the Department of Science Teaching at the Weizmann Institute of Science, Israel. The project's general goal was to teach chemistry concepts in the…

The ongoing reform in science education in many countries, including Israel, has attainment of scientific literacy for all as one of its main goals. In this context, it is important to provide teachers with the opportunity to construct meaning for the term science literacy and by doing so to obtain a clear understanding of the new teaching goals.…

An inquiry-type laboratory was implemented into the chemistry curriculum in high schools in Israel. The study included development of inquiry-type experiments, assessment tools for a continuous assessment of students' achievements and progress, and a long-term professional development program for teachers who decided to implement the program in…

The goal of this study was to investigate whether integrating a website into chemistry teaching influences 10th-grade students' perceptions of the classroom learning environment, their attitudes regarding the relevance of chemistry, and their understanding of the concept of chemical bonding. Two groups participated in this study: an experimental…

We describe a workshop in which 10 teachers from 10 schools, located in central Israel, participated in the development of alternative assessment tools in the context of implementing a new science curriculum for senior high-school students, namely "Science for All" (an STS type curriculum). In order to assist a group of teachers (who began…

In order to cope with complex issues in the science-technology-environment-society context, one must develop students' high-order learning skills, such as question-asking ability (QAA), critical thinking, evaluative thinking, decision-making, and problem-solving capabilities within science education. In this study, we are concerned with evaluating…
