Merrill, Stephen J. – International Journal of Science and Mathematics Education, 2007
Science and mathematics education needs to serve several (possibly contradictory) motivating goals. One is found in the movement for a universal literacy in the central principles and methods of the disciplines. The second is the need to provide the experiences and background that makes possible the production of scientists and engineers. A…

Dana-Picard, Thierry – International Journal of Science and Mathematics Education, 2007
The constraints of a computer algebra system (CAS) generally induce limitations on its usage. Via the pedagogical features implemented in such a system, "motivating constraints" can appear, encouraging advanced theoretical learning, providing a broader mathematical knowledge and more profound mathematical understanding. We discuss this issue,…

Parameswaran, Revathy – International Journal of Science and Mathematics Education, 2007
In this paper we explore the influence of students' personalized notion of "small" numbers based on real life experiences on their understanding of limits. Tests were conducted on two samples of students. The first sample, consisting of students in the XII grade, had been taught limits using an informal approach (i.e., without recourse to the…

Wang, Jing-Ru – International Journal of Science and Mathematics Education, 2007
The purpose of the study was to explore students' alternative conceptions and their associative thinking regarding internal transport in plants through administration of a refined diagnostic test. Questions of associative thinking and explanation were added to form a third tier of the previous two-tier test. The study found three terms related to…

Mintzes, Joel; Quinn, Heather J. – International Journal of Science and Mathematics Education, 2007
Emerging from a human constructivist view of learning and a punctuated model of conceptual change, these studies explored differences in the structural complexity and content validity of knowledge about prehistoric life depicted in concept maps by learners ranging in age from approximately 10 to 20 years. Study 1 (cross-age) explored the…

Wiebe, Eric N.; Slykhuis, David A.; Annetta, Leonard A. – International Journal of Science and Mathematics Education, 2007
Slideware applications (e.g., PowerPoint) have become more prevalent in instruction across disciplines. This is especially true at post secondary institutions where many instructors are using slideware as a sole instructional tool. This study evaluated the relative effectiveness of scientific visualization in two PowerPoint delivery strategies on…

Meaney, Tamsin – International Journal of Science and Mathematics Education, 2007
Mathematical literacy, viewed as a set of ideas involving applications of mathematics to real-world contexts, has recently featured in curricular discussions about the aims for mathematics education. This article explores the effect that differences in the way that a mathematical task is contextualised can have on students' mathematical arguments…

Kawasaki, Ken – International Journal of Science and Mathematics Education, 2007
This article presents an axiomatic expression of science education: [SCIENCE EDUCATION] is a system of teaching [SCIENCE]. The axiom includes two indefinable terms, [SCIENCE EDUCATION] and [SCIENCE]. In the same way that axiomatics of geometry distinguishes among axioms, postulates and theorems, the axiom presupposes a distinction among the three…

Yore, Larry D.; Pimm, David; Tuan, Hsiao-Lin – International Journal of Science and Mathematics Education, 2007
This opening article of the Special Issue makes an argument for parallel definitions of scientific literacy and mathematical literacy that have shared features: importance of general cognitive and metacognitive abilities and reasoning/thinking and discipline-specific language, habits-of-mind/emotional dispositions, and information communication…

Taber, Keith S.; Tan, Kim Chwee Daniel – International Journal of Science and Mathematics Education, 2007
This paper describes findings from a study to explore Singapore A-level (Grades 11 and 12, 16-19 yr old) students' understanding of ionisation energy, an abstract and complex topic that is featured in school chemistry courses. Previous research had reported that students in the United Kingdom commonly use alternative notions based on the perceived…

Yip, Din Yan; Tsang, Wing Kwong – International Journal of Science and Mathematics Education, 2007
A longitudinal study has been conducted to explore the impact of a new language policy for Hong Kong secondary schools on science learning. According to this policy, only schools that recruit the best 25% of students can teach science in English, the students' second language, while the other schools have to teach science in Chinese, the students'…

Elia, Iliada; Panaoura, Areti; Eracleous, Anastasia; Gagatsis, Athanasios – International Journal of Science and Mathematics Education, 2007
The present study explores pupils' constructed definitions of the concept of function in relation to their abilities in dealing with tasks of functions involving different forms of representations and problem solving tasks. A major concern is also to examine the interrelations between these three ways of thinking about or dealing with the concept…

Anderson, John O.; Lin, Huann-Shyang; Treagust, David F.; Ross, Shelley P.; Yore, Larry D. – International Journal of Science and Mathematics Education, 2007
Large-scale assessments of student achievement provide a window into the broadly defined concepts of literacy and generate information about levels and types of student achievement in relation to some of the correlates of learning, such as student background, attitudes, and perceptions, and perhaps school and home characteristics. This paper…

Hsu, Pei-Ling; Yang, Wen-Gin – International Journal of Science and Mathematics Education, 2007
Systemic functional linguistics (SFL) was the foundation for this study that explored the effect of science text and image integration on grade 9 students' reading comprehension. Two texts in Chinese on the moon phase with different print and image integration were compared--a traditional textbook (TT) used in Taiwanese junior high schools and a…

Keraro, Fred Nyabuti; Wachanga, Samuel W.; Orora, William – International Journal of Science and Mathematics Education, 2007
This study investigated the effects of using the cooperative concept mapping (CCM) teaching approach on secondary school students' motivation in biology. A non equivalent control group design under the quasi-experimental research was used in which a random sample of four co-educational secondary schools was used. The four schools were randomly…
