A study was conducted on how scientific laboratory lessons contribute to building arguments, both cognitively and socially. The population consisted of 12 second-year pre-service teachers at a college of education specializing in the teaching of biology and chemistry in middle school. The study examines the nature of the arguments students raise…

In this study we explored whether the use of teachers' demonstrations significantly improves students' understanding of redox reactions compared with control group counterparts who were not exposed to the demonstrations. The sample consisted of 131 Israeli 8th graders in middle schools (junior high school). Students' attitudes and achievements as…

The present research is part of a longitude research study regarding the questioning behavior of students in the inquiry chemistry laboratory in Israel. We found that students who were involved in learning chemistry by the inquiry method ask more and higher-level questions. However, throughout the years, we have observed that differences between…

This paper describes the rationale and the implementation of five laboratory experiments; four of them, intended for high-school students, are inquiry-based activities that explore the quality of water. The context of water provides students with an opportunity to study the importance of analytical methods and how they influence our everyday…

This paper presents a study focusing on differences in Israeli Jewish and Arab chemistry teachers' beliefs regarding teaching and learning of chemistry in the upper secondary schools. Israel is a country experiencing the problems of diverse cultural orientation of its inhabitants but applying the same educational system to its diverse cultural…

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…

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,…

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…

In order to help teachers to bring their students into contact with the frontiers of chemistry, a special program for enhancing chemistry teachers' content knowledge as well as their pedagogical knowledge was launched at the Weizmann Institute of Science. The program, which was specifically designed for the chemistry teachers, consists of three…

Traditional curriculum for teaching bonding often fosters the use of over-simplifications and over-generalizations. Therefore, there is a need for a presentation that is consistent with current scientific knowledge and that provides the student with the proper intellectual infrastructure for further studies. In this article, we present a general…

Discussions held in the chemical education community have generated a variety of reports and recommendations for reforming the chemistry curriculum. The recommendations refer to teaching chemistry in the context of real-world issues. This has been suggested as a way to enhance students' motivation. It is suggested that real-world problems…

The study described in this article is based on a long-term comprehensive series of investigations that were conducted in the context of teaching high school chemistry in the laboratory using inquiry-type experiments. The students that study chemistry according to this program are involved in an inquiry process that included all the inquiry skills…

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…

Reforms in science education in general and in chemistry education in particular have been introduced in many countries since the beginning of the 21st Century. Similarly, at this time in Israel both the content and pedagogy of the chemistry curriculum in high schools were reformed. New content and pedagogical standards emerged, fostering…

An inquiry-oriented laboratory in chemistry was integrated into the chemistry curriculum in Jewish high schools in Israel, and after a short period was also implemented in Arab sector. In this study, we investigated the effect of culture on the perceptions of laboratory classroom learning environments by comparing the perceptions of Arab and…
