The purposes of this study are to investigate whether pre-service middle school mathematics teachers evaluate discussions in the cases regarding proof by contradiction correctly, to what extent they explain their correct evaluations by referring to proof by contradiction, and the reasons of their misinterpretations of discussions in the cases…

Background: Youth obesity in the United States is a major health concern. Obesity can be reduced by increasing health-promoting behaviors. Purpose: The goals of the present study were to (1) identify the strongest motivators of and barriers to health-promoting behaviors among a culturally diverse group of middle and high school students and (2)…

The purpose of this study is to determine types of games that middle school students play in their daily lives and analyze the effects of various variables such as gender, available technology, grade in school and parents' education levels on their game preferences. The sample consisted of a total of 464 grade 5-8 students (212 girls and 252…

Previous research suggests that students participating in school-based musical ensembles are more engaged in school and more likely to connect to their peers in school; however, researchers have not specifically investigated peer connectedness among adolescents in school-based music ensembles. The purpose of this study was to explore middle school…

Understanding students' misconceptions and how they change is an essential part of supporting students in their science learning. This paper presents results from distractor-driven multiple-choice assessments that target students' misconceptions about energy. Over 20,000 elementary, middle and high school students from across the U.S. participated…

This study explored the relationship between school level and the psychosocial construct of an academic mindset operationalized on the Likert-style Project for "Educational Research That Scales" (PERTS) instrument; widely used in testing academic mindset interventions at the classroom level. Analyses were conducted using existing school…

Prior research demonstrates that perceived academic support from peers positively predicts school adjustment. In this cross-sectional study, we provide evidence that perceived academic support from peers declines from 3rd to 8th grade and that this decline is partially mediated by grade-level declines in perceptions that academic success…

This study focuses on the development of the understanding of historical time of pupils in primary school. We present a developmental model with three stages: "emergent," "initial" and "continued" understanding of historical time. Based on this model, we constructed an instrument to measure how pupils aged 6-12…

Student's ability to use and manipulate scientific concepts has been widely explored; however there is still a need to define the characteristics and nature of science ability. Also, the tests and performance scales that require minimal conceptual knowledge to measure this ability are relatively less common. The aim of this study was to develop an…

The average temperature on the Earth's surface has globally increased. This issue was generally caused by the increasing of greenhouse gases concentrations due to human activities. Therefore, the knowledge about global warming becomes major topics for students and educators. This research aimed to investigate how the teachers and students…
