Investigated behavioral decision-making theories of bounded rationality and satisficing in relation to young people's decision making in the World Wide Web and considered the role of personal preferences. Results of this study of ninth- and tenth-grade females consider time constraints, information overload, physical constraints, reduction…

Investigates the extent to which a new general science curriculum reflecting a constructivist view has influenced the science classroom learning environment in Korea. Results from a validated Korean Constructivist Learning Environment Survey (CLES) indicate that grade 10 students perceived a more constructivist learning environment than grade 11…

A school transition project examined effects on sleep and circadian rhythms in a group of 25 youngsters shifting from an 8:25 a.m. junior high school starting time to a 7:20 a.m. high school starting time. The average amount of sleep on school nights fell substantially for 9th and 10th graders, and was below the amount required for normal…

This study investigated their views concerning evidence and expert opinion of 10th-grade students, accessed by an open-ended questionnaire in the context of a socio-scientific issue: the cause of flood disasters, and personal epistemology identified by the "Learning Environment Preference Questionnaire" (LEP). Students' responses to the open-ended…

Past research has indicated an association between parents' beliefs and adolescent children's self-perceptions of ability and has shown the importance of accounting for parents' gender-stereotyped beliefs when examining boys' and girls' self-perceptions of math-science ability. The current study extends these findings by examining the longitudinal…

The expertise reversal effect occurs when a learning procedure that is effective for novices becomes ineffective for more knowledgeable learners. The authors consider how to match instructional presentations to levels of learner knowledge. Experiments 1-2 were designed to develop a schema-based rapid method of measuring learners' knowledge in a…

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 current studies were designed to examine whether female adolescents have more negative reactions than male adolescents to achieving more than their same-sex friends. In Study 1, 51 females and 48 males from grades 8 and 10 were administered questions assessing their reactions to performing better than their closest same-sex friends in four…

The study explored how Grade 10 science students learned from scientific graphs. This paper explores (a) students' abilities to interpret graphical information; (b) students' abilities to represent information graphically; (c) factors that could impede the process of interpretation and construction of graphs among secondary school science…

This study examined several aspects of Passage Reading Fluency (PRF) including performance variability across passages alternative designs for measuring PRF gain, and effects on PRF level from retesting with the same passages. Participants were 33 students from grades 2 to 10 attending a school for students with learning disabilities. PRF was…

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…

The terrorist attacks of September 11, 2001, have had tragic effects for history teachers and students in Canada, the United States, and abroad. Yet, despite increased educational research in historical thinking, very little is known about students' historical understanding of terrorism. This exploratory study looks at some Canadian, but…

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…
