Mathematics related affect turn from positive to negative during comprehensive school years worldwide. There is a clear need to find solutions to the problem. However, some gaps and problems appear in the methodologies and the common approaches used in the field. This article discusses five studies addressing affective development, challenges some…

Proof and proving are important components of school mathematics and have multiple functions in mathematical practice. Among these functions of proof, this paper focuses on the discovery function that refers to invention of a new statement or conjecture by reflecting on or utilizing a constructed proof. Based on two cases in which eighth and ninth…

Research indicates that mathematics coursetaking is related to positive academic and economic outcomes. Studies have found that high school students who take more rather than fewer mathematics courses are more likely to attend college and to have higher levels of educational attainment.

Diagram describing texts are integral part of science and engineering subjects including geometry, physics, engineering drawing, etc. In order to understand such text, one, at first, tries to draw or perceive the underlying diagram. For perception of the blind students such diagrams need to be drawn in some non-visual accessible form like tactile…

Russian society finds itself in a state of dynamic transformation. It is developing intensively and becoming more complex in its structure against the background of an increasing diversity of cultures and forms of interaction among people, along with economic differentiation, national and religious differences, and so on. These factors give rise…

The authors aimed to propose a valid and reliable diagnostic instrument by developing a three-tier test on simple electric circuits. Based on findings from the interviews, open-ended questions, and the related literature, the test was developed and administered to 124 high school students. In addition to some qualitative techniques for…

Introduction: Due to a considerable lack in empirical efforts and appropriate instruments, and theoretically rooted in a cognitive-motivational perspective on academic personality development, the present study analyzes a questionnaire for measuring EFL learners' self-perceptions of oral narrative competencies and perceived anxiety concerning oral…

Many models assume that habitual human behavior is guided by spontaneous, automatic, or implicit processes rather than by deliberate, rule-based, or explicit processes. Thus, math-ability self-concepts and math performance could be related to implicit math-gender stereotypes in addition to explicit stereotypes. Two studies assessed at what age…

The current study describes longitudinal trends in sexual harassment by adolescent peers and highlights gender, pubertal status, attractiveness, and power as predictors of harassment victimization. At the end of 5th, 7th, and 9th grades, 242 adolescents completed questionnaires about sexual harassment victimization, pubertal status, and perceived…

This study examined the intercultural sensitivity of Finnish 12-16-year-old secondary school students (N=549) with a 23-item Intercultural Sensitivity Scale Questionnaire (ICSSQ). The ICSSQ is based on Bennett's (1993) Developmental Model of Intercultural Sensitivity (DMIS), which is a conceptual tool to situate certain reactions towards cultural…

This report examines the results of the field test for the base year of the High School Longitudinal Study of 2009 (HSLS:09). The general purposes of the field test were, in anticipation of the base-year full-scale effort, to test instruments, forms, and procedures; to experiment with different approaches to questionnaire content and survey…

A two-part screening procedure was used to assess school-age children's experience with bullying.
