The life work of both John Dewey and Lev Vygotsky and the implications for pedagogy that each of the theorist's work has generated is well known in the field of education. However, it is seldom that the theorists' works are juxtaposed for pedagogical considerations for specific subject matter. This is for at least three reasons: first, Dewey, of…

The purpose and validity of the HSGP objectives are closely examined, selection and sequence of concepts are analyzed in terms of their academic, commercial and political expediency. The writer is a visiting academic on study leave from Australia. (Author/JB)

A contest for general mathematics students is briefly described. It includes tests, congratulatory letters, and face-to-face competition. (MP)

Two intact chemistry classes participated in a study and the same teacher taught both a line graphing unit with computer-supported activities and one without. Results indicate that there were no statistically significant interaction effects among treatments and scientific reasoning levels. (Contains 40 references.) (Author/NB)

Explored where bullying occurred, what kind of bullying happened, how often bullying occurred, and whom students confided in when bullying occurred at school. Surveys of rural 9th and 10th graders indicated that bullying was a very real part of their daily lives. Nearly 75 percent reported some type of bullying at school, and many observed…

Describes a unit of laboratory work which was unusual in that the teacher's purpose was to develop students' understanding of the way scientific facts are established with little expectation that they would understand the science content involved in the experiments. The unit was very successful from both a cognitive and affective perspective.…

Learning physics is a complex phenomenon. In this article, we use concepts from the theory of nonlinear systems to study the development of language in classroom science in an experimental unit on chaos theory in a German 10th-grade physics classroom. In ongoing activity, the explanations students developed for phenomena emerged through…

Many students have traditionally found the processes of algebraic manipulation, especially factorisation, difficult to learn. This study investigated the value of introducing students to a Vedic method of multiplication of arithmetic numbers to algebra that is very visual in its application. This research considered a possible role of the…

The present study aimed to investigate the effect of conceptual change texts oriented instruction on 10th grade students' understanding of solubility equilibrium concept. The misconceptions related to solubility equilibrium concept were obtained through interviews with high school chemistry teachers and related literature. The data were obtained…

This study represents the first attempt to elucidate and detail the types of misconceptions high school students hold relating to basic concepts and topics of nuclear chemistry. A diagnostic multiple-choice test was administered to 157 tenth-grade students (15-16 years old) and the data were analyzed. The results show that high school students…

This paper addresses the dialectical relation between theoretical thinking and technique, as they co-emerge in a combined computer algebra (CAS) and paper-and-pencil environment. The theoretical framework in this ongoing study consists of the instrumental approach to tool use and an adaptation of Chevallard's anthropological theory. The main aim…

The aim of the present study was to examine the characteristics of separation-individuation in Turkish high school students and to investigate the contribution of sociodemographic variables on this second individuation process of adolescence. The sample consisted of 618 adolescents between the ages of 14 and 18 in three urban and two rural high…

The purpose of this study is to investigate the effectiveness of response modes by item and feedback type in a web-based language learning program. The subjects of this study, 122 Korean tenth graders learning English as a foreign language, were placed into groups of four and were given a web-based language learning program consisting of two…

The discrepancies between test-based and teacher-based criteria of high achievement are well-documented for students of all ages. This study seeks to determine whether certain high school students who score high on tests of academic achievement are more likely than others to be nominated for advanced academic programs by their teachers. Using…

Despite the success of many drug and alcohol prevention programs, drug and alcohol use by adolescents continues to be a problem. One important factor in preventing drug and alcohol use may be determining, in a non-intrusive manner, which students are most at risk for drug involvement. In the present study, the predictive relationship between…
