This paper examines the way two 10th graders cope with a non-standard generalisation problem that involves elementary concepts of number theory (more specifically linear Diophantine equations) in the geometrical context of a rectangle's area. Emphasis is given on how the students' past experience of problem solving (expressed through interplay…

This study investigated whether intuitive, naive conceptions of "living things" based on objects' mobility (movement = alive) persist into adolescence and affect 10th graders' accuracy of responses and reaction times during object classification. Most of the 58 students classified the test objects correctly as living/nonliving, yet they…

Intentional self regulation describes how people make choices, plan actions to reach their goals, and regulate the execution of their actions, making processes of intentional self regulation central to healthy human functioning. Prior research has confirmed the presence of three processes of intentional self regulation--elective selection (ES),…

This study explored the effects of congruency between preferred and actual learning environment (PLE & ALE) perceptions on students' science literacy in terms of science concepts, attitudes toward science, and the understanding of the nature of science in an innovative curriculum of High Scope Project, namely Sci-Tech Mind and Humane Heart…

This paper explores which classroom and teacher factors are associated with post-16 mathematics aspirations, mathematics intrinsic motivation, and mathematics self-concept. Few studies explore all three outcomes among the same set of students or make linkages across the factors that are important to these outcomes. The analysis is based on the…

Exergames (active video games that require kinesthetic movement) played in proximity to other players or against a gaming machine have been linked to positive increases in cognitive functioning. This study tested to see if remote exergame play over the Internet had an impact similar to exergames that are played in proximity. The study shows that…

Robotics competitions for K-12 students are popular, but are students really learning and improving their STEM scores through robotics competitions? If not, why not? If they are, how much more effective is learning through competitions than traditional classes? Is there room for improvement? What is the best robotics competition model to maximize…

This paper discusses a K-12/university collaboration in which students participated in a four-day scenario-based summer STEM (science, technology, engineering, and mathematics) camp aimed at making difficult scientific concepts salient. This scenario, Jumpstart STEM-CSI: Chocolate Science Investigation (JSCSI), used open- and guided-inquiry…

This study investigated how a teacher in a multilingual classroom attempted to support learners who are struggling to translate written/verbal mathematics into a symbolic form. Thirty-six Grade ten learners in one multilingual classroom in South Africa were given a written test involving one algebraic question and then a discussion on the solution…

The focus of the study was to identify secondary school students' difficulties with aspects of linearity and linear functions, and to assess their teachers' understanding of the nature of the difficulties experienced by their students. A cross-sectional study with 1561 Grades 8-10 students enrolled in mathematics courses from Pre-Algebra to…

In recent years, the numbers of girls in secondary and tertiary education studying Physics have declined. This research sought to investigate Years 10 and 11 female students' views about Physics and their physics teachers and was conducted in an all-girls independent school. While the findings show that in general these students do not relate well…

This study investigates the contribution of second-language (L2) morphological awareness to foreign language reading comprehension. Tenth graders (n = 188) at a South Korean high school were assessed on 6 reading- and language-related variables: phonological decoding, listening comprehension, vocabulary knowledge, passage-level reading…

In October 2010 Perry Beeches school, an 11-16 Local Authority controlled community comprehensive in Birmingham, was widely featured in the national media as the "most improved school in the UK"--Ever. Some of the ways in which this was achieved are explored. Whether the changes undergone by this school reflect a pattern that has become…

Using data from the 4-H Study of Positive Youth Development, a longitudinal study involving U.S. adolescents, multi-group structural equation modeling (SEM) was used to evaluate whether news media use is predictive of a set of civic indicators (civic duty, civic efficacy, neighborhood social connection, and civic participation) for youth in Grades…

Two theoretical perspectives have been proposed to describe, explain, and intervene in adolescent development--prevention science and positive youth development (PYD). An integrative model bridging these two perspectives posits that it is important to assess the extent to which the same, similar, or complementary mechanisms may be responsible for…
