This contribution reports the process and outcomes of a multiyear effort that supported institutions in reforming general chemistry using multidimensional learning approaches in the form of performance expectations. Performance expectations are based on evidence-centered assessment design principles and describe what learners should be able to do…

The aim of this study was to reveal the effects of Problem-based Learning (PBL) on the metacognitive awareness and attitudes toward chemistry of teacher candidates with different academic backgrounds. The study was carried out on one group using both pre-and post-test experimental studies. The findings of the study were obtained through…

An inquiry-based laboratory activity to determine the chemical composition of a component in alkaline detergents, sodium sesquicarbonate (SSC), is proposed. On the basis of introductory demonstrations by the instructor on the chemical properties and reactions of SSC, students propose the hypothetical composition of SSC and possible quantitative…

Over the past 20 years research on reform efforts aimed at the chemistry laboratory has focused on different aspects of students' experiences including increasing content knowledge, improving student attitudes toward chemistry, incorporating inquiry activities, and providing students a hands-on experience related to the chemistry concepts learned…

Lightsticks, or glowsticks as they are sometimes called, are perhaps the chemist's quintessential toy. Because they are easy to activate and appealing to observe, experimenting with lightsticks provides a great way to get young people interested in science. Thus, we have used lightsticks to teach chemical concepts in a variety of outreach settings…

The aim of this study is to investigate Emiratii high school students' understandings of stoichiometry, their use of metacognitive strategies, and the influence of students' use of metacognitive strategies on their understandings of stoichiometry. Two instruments were used in this study, the first to measure students' understandings of…

Currently not many people would doubt that computers play an essential role in both public and private life in many countries. However, somewhat surprisingly, evidence of computer use is difficult to find in German state schools although other countries have managed to implement computer-based teaching and learning in their schools. This paper…

"Chemistry That Applies" is an instructional unit designed to help students in grades 8-10 understand the law of conservation of matter. It consists of 24 lessons organized in four clusters. Working in groups, students explore four chemical reactions: burning, rusting, the decomposition of water, and the reaction of baking soda and…

Interdisciplinary science teaching is an issue in various countries. One example in Europe is Germany, especially regarding comprehensive schools. At the same time, German teacher education is primarily subject-specific. An examination of data on self-efficacy beliefs is helpful for understanding the qualifications of teachers for…

This paper scrutinizes the contribution of Romulo de Carvalho to the development of the Portuguese science curriculum, arguing that it was critically informed by his lifetime inclination to the humanities. It focuses on a particular historical event: the 1948 chemistry programme for the secondary school "Liceus". The paper briefly…

In accordance with the requirements for the National Curriculum Statement for both Life sciences and Physical sciences and the importance of community engagement in Higher Education in South Africa, this paper described the use of the lecture-demonstration "A Pollutant's Tale" to create climate change awareness amongst school learners.…

The council of the American Association for the Advancement of Science, at its Cincinnati, Ohio meeting in December, 1923, authorized a special committee to make a study of the role played and to be played by science in education. That committee was organized in 1924, and the presentation of this bibliography is a product of its work. An adequate…

We describe an inquiry-based course in physics and chemistry for preservice K-8 teachers developed at California State University Fullerton. The course is one of three developed primarily to enhance the science content understanding of prospective teachers. The course incorporates a number of innovative instructional strategies and is somewhat…

This bulletin lists materials available in the fall of 1963 to assist educators in their selections of programmed instruction materials, and updates the inaugural issue, "Programs '62." Since the 1962 edition provided a number of first analyses of programmed material available, some of the present statistical data have been related to last year's…

This paper reports a study on teachers' domain-specific beliefs about the chemistry curriculum for upper-secondary education in The Netherlands. Teachers' beliefs were investigated using a questionnaire focused on the goals of the chemistry curriculum. The design of the questionnaire was based on three curriculum emphases: "fundamental…
