This paper reports on study that investigated the tacit-explicit dimension of the learning of mathematics. The study was carried out in a secondary school and consisted of an episode analysis related to a class discussion about the difference between plane figures and spatial figures. The data analysis was based on integration between some aspects…

There is an expectation that new science teachers will be able to effectively use a range of information communication technology (ICT) related resources in the science classroom in order to enhance student learning. All school systems in Australia are in the process of providing teachers with ICT professional development and infrastructure. This…

When the United Nations General Assembly authorized holding the World Summit on Sustainable Development (WSSD) in Johannesburg, it was hardly a secret--or even a point in dispute--that progress in implementing sustainable development had been disappointing since the 1992 Earth Summit in Rio de Janeiro. With poverty deepening and environmental…

This paper discusses the problem of social exclusion, reported to be intrinsically connected to mathematical teaching from the perspective of Hegel's philosophy and Lacan's psychoanalysis. It provides a characterization of mathematics from a language viewpoint discusses the perennial demand for more mathematical achieving from the perspective of…

This study examines U.S. and Chinese teachers' constructing, knowing, and evaluating representations to teach the concept of ratio. All Chinese lesson plans are very similar with details in teaching contents and procedure. The U.S lesson plans are extremely varied although they all adopted the "outline and worksheet" format. Both the Chinese and…

The study investigated elementary school pupils' ideas concerning the concept of electricity and the effect of school instruction on the pupil's views. Pupils of different cultural backgrounds were assessed to ascertain their knowledge in four areas: Relation of certain natural phenomena to electricity; Mental models (images) of direct current in…

First-year chemistry classes typically comprise of a mixture of majors and non-majors. Reports in the literature suggest that students have lower self-efficacy for subjects outside their intending major. Here we report on research that examines changes in chemistry students' chemistry self-efficacy throughout their first year of chemistry study at…

This paper presents a cross-cultural study on the intuitive rules theory. The study was conducted in Australia (with aboriginal children) in Taiwan and in Israel. Our findings indicate that Taiwanese and Australian Aboriginal students, much like Israeli ones, provided incorrect responses, most of which were in line with the intuitive rules. Also,…

The basic unit of school based mathematics teaching is the lesson. This article is a contribution to understanding teacher actions that facilitate successful lessons, defined as those that engage all students, especially those who may sometimes feel alienated from mathematics and schooling, in productive and successful mathematical thinking and…

Fully half of the curriculum at Roskilde University in Denmark is student-driven group research project work that is often interdisciplinary. Describes the practice of group project work in the sciences at RUC and evaluates implications for educational practice in the United States. (Author/SAH)

Analyzes 295 male and 194 female examinations from introductory atmospheric and oceanic science courses to determine whether or not there exist gender differences in the performance on multiple choice versus constructed response sections of the exams. (Author/SAH)

Describes a successful pilot program to develop and test a program that facilitates the linking of undergraduate research and education through radio astronomy. Based on the pilot experiences, students everywhere should be able to exploit the opportunity to strengthen their education through practical research using radio astronomy. (Author/SAH)

Discusses the reliability and versatility of using photovoltaics whereby solar cells convert sunlight directly into electricity. The growing concern of global warming promises to transform photovoltaics into a major energy producer. (Author/SAH)

Explores the effects of a Problem-based Computer-Assisted Instruction (PBCAI) on students' earth science achievement in Taiwan. One hundred and fifty-nine 10th grade students enrolled in four sections of a mandatory earth science course participated in this pretest- posttest control group experiment. A significant difference was found between the…

Considers main education trends while society is moving towards a totally new information environment--cyberspace. Justifies and specifies the aims and tasks of education. Suggests a new pedagogical technology, projective pedagogy, as a solution. (Author/SAH)
