This article presents research on students' understanding of basic concepts in Graph Theory. Students' understanding is analyzed through the lens of the theoretical framework of reducing abstraction (Hazzan, 1999). As it turns out, in spite of the relative simplicity of the concepts that are introduced in the introductory part of a traditional…

In this paper, we report on a study of the beliefs of chemistry teachers about the teaching and learning of chemistry in upper secondary education in The Netherlands. This study was conducted in the context of the planning of a national revision of the chemistry curriculum towards a context-based approach. Chemistry teachers' beliefs were…

In the autumn of 2004, an interdisciplinary social science course entitled "Remembering, Forgetting and Forgiveness: Justice and Reconciliation from the National to the International" was offered to undergraduate students at the University of Tampere, Finland. The course had 49 students from 10 different countries on three continents. A…

At the beginning of each year, teachers have the daunting task of deciding which concepts and skills to teach their students. Many teachers feel the pressure to teach "the whole book". This pressure comes in multiple forms. There is ever-increasing pressure to perform well on state, national, and international exams. An added pressure is the…

A recent UK House of Commons report on Science 14-19 identified problems with coursework and argued for a greater emphasis on teaching and assessment of scientific literacy. This paper describes a written test for procedural understanding, given to 15 year olds, that addresses both of these issues. Comparisons are made between the scores on a…

Taking the Junior Secondary School Chemistry Curriculum (JSSCC) in the People's Republic of China as a case, this paper approaches the issue of the tension between elite and future citizenry orientations in science curriculum. The changes in the JSSCC over the period from 1978 to 2001 are explained from three viewpoints: sociopolitical,…

Creating inquiry- and standards-based science curricula that meet wide-ranging learner needs and preferences requires strategic planning and organization. The common practice of retrofitting or modifying existing instructional and curriculum materials to accommodate individual learner needs too often overshadows the concept of designing universal…

This study continues research previously conducted by a nine-university collaborative, the Salish I Research Project, by exploring science teachers' beliefs and practices with regard to inquiry-oriented instruction. In this study, we analyzed the relationship among secondary science teachers' preparation, their beliefs, and their classroom…

"Science Education and Student Diversity: Synthesis and Research Agenda" (Lee & Luykx, in press) analyzes and synthesizes current research on how racial/ethnic, cultural, linguistic, and socioeconomic variability affects science achievement among K-12 students who have traditionally been underserved by the education system. The book begins with…

Humans have long pondered the question of life's origins on Earth and sought to understand their place in the vast expanse of the Universe. Are they alone, in which case the inception of life is a phenomenon unique to planet Earth, or will they find signs of life on other terrestrial bodies? Today, technology allows space probes and rovers to…

The teaching of crystal structure determination with single-crystal X-ray diffraction at undergraduate level faces numerous challenges. Single-crystal X-ray diffraction is used in a vast range of chemical research projects and forms the basis for a high proportion of structural results that are presented to high-school, undergraduate, and graduate…

Recent reform movements within the United States have called for science for all and educational reforms to support this goal. In light of these reform movements and concerns regarding learning within urban schools, science educators and policy makers have pushed for the incorporation of learning technologies within schools as a way of creating…

Are traditional laboratories in the core introductory biology courses teaching physiology majors the art and trade of science, or simply leaving them with a memory of trivial experiments done for unknown reasons? Our students, a population dominated by premed and physiology majors, think the latter and have encouraged us to challenge this model,…

The ideas in this article arose from the National Union of Teachers' professional development programme "Putting life into science -- primary science and citizenship" that the author ran with Will Ord from SAPERE. As with other NUT "Teacher 2Teacher" programmes, this course had two major inputs, in January and June, with the intervening time…

In this article, the author describes the educational potential of a garden project. When the opportunity to visit a school in Amsterdam arose as part of her primary science PGCE course, the author jumped at the chance to experience science learning in another country. The majority of teaching that took place was topic-based, and science was…
