Within the realm of teaching middle and high school mathematics, the ability to teach mathematics effectively using various forms of technology is now more important than ever, as expressed by the recent development of the Common Core State Standards for Mathematical Practice. This article presents the development process and the results from 15…

Recent research has evaluated the motivational functions of educational games and its potential role for the teaching of reading skills. Educational games must maintain their educational function retaining clear definitions of the teaching objectives and instructional methods. Reading skills can be broken down into more basic behavioral units.…

In this paper, we provide evidence of the impact of early algebra (EA) over time. We document this impact in the following ways: (a) by showing the performance over time of an experimental group of 15 children on an algebra assessment, from 3rd to 5th grade; and (b) by showing how the performance on an algebra assessment of children from an…

Technological pedagogical and content knowledge (TPACK) has been one of the steering theoretical concepts widely employed by researchers in order to examine and develop teachers' knowledge of integrating technology into teaching. Existing research on TPACK shows little about in-service secondary school science teachers' TPACK through a…

The effect of creating blog-based portfolios on knowledge management (KM) abilities among university students was examined in the present study. Participants included 43 students majoring in Multimedia and Game Science at a University in Taiwan. Students spent nine weeks creating their personal portfolios by using a blog. The "t"-test…

Introduction: The aim of this study was to verify whether the six-dimension structure of the Physical Self-Concept Questionnaire is maintained with Chilean students, and to assess its psychometric qualities in this population. Method: One thousand seven hundred sixty-seven students took part in this research, from Central and South Chile; 45.8%…

The New Horizon ("Ofek Hadash" in Hebrew) educational reform agreement was signed between the Israeli government and the Teachers' Union in 2008. The purposes of the educational reform document were (a) to improve students' achievements, (b) to provide fair recompense to teachers, and (c) to strengthen teachers' status in society.…

The present study introduced "agentic engagement" as a newly proposed student-initiated pathway to greater achievement and greater motivational support. Study 1 developed the brief, construct-congruent, and psychometrically strong Agentic Engagement Scale. Study 2 provided evidence for the scale's construct and predictive validity, as…

With ever increasing exposure to computer games, gaining an understanding of the attitudes held by young adolescents toward such activities is crucial; however, few studies have provided scales with which to accomplish this. This study revisited the Computer Game Attitude Scale developed by Chappell and Taylor in 1997, reworking the overall…

Background: Preliminary data were collected to evaluate the psychometric properties of an emotional self-efficacy (ESE) measure in a sample of 3836 public high school adolescents who completed the Centers for Disease Control and Prevention (CDC) Youth Risk Behavior Survey in South Carolina. Methods: Principal axis factor analysis was followed by a…

Recent studies suggest that there appears to be a similar developmental sequence in the understanding of mental states in both internal-state language and in standard theory-of-mind tasks. These findings suggest possible developmental relations between children's ability to talk and think about the mind. Two experiments investigated the concurrent…

This study explored the nature of mathematics anxiety in a sample of 106 ethnically and linguistically diverse first-grade students. Although much is known about mathematics anxiety in older children and adults, little is known about when mathematics anxiety first emerges or its characteristics in young children. Results from exploratory factor…

Using Petronio's communication privacy management theory, this study tested the degree to which content relevance and students' comfort with instructor disclosures moderated the association between instructor disclosures (i.e., frequency and appropriateness) and credibility (i.e., competence, trustworthiness, and goodwill) in the college…

To assess the measurement properties of a new QOL instrument, the Cerebral Palsy Quality of Life Questionnaire-Teen (CP QOL-Teen), in adolescents with cerebral palsy (CP) aged 13-18 years, examining domain structure, reliability, validity and adolescent-caregiver concordance. Based on age, 695 eligible families were invited to participate by mail.…

Background: Parenting and children's adjustment were examined in 30 surrogacy families, 31 egg donation families, 35 donor insemination families, and 53 natural conception families. Methods: Parenting was assessed at age 3 by a standardized interview designed to assess quality of parenting and by questionnaire measures of anxiety, depression, and…
