This study explores misperceptions about peer norms in support of telling authorities about weapons at school and whether perceptions predict personal support for telling authorities. Anonymous surveys were conducted among youth in 30 schools (Grades 5-12) in six states (n = 12,903) between 2006 and 2014. Personal support for telling principals,…

This study aimed to determine the extent of pre-service science teachers' (PTS) process and materialistic understanding of sound concept and the role of their task value beliefs in their scientific conception of sound. With this aim, the Sound Concept Inventory Instrument (SCII) was translated and adapted to Turkish. The SCII was administered to…

One of the foundational assumptions in education is that greater teacher knowledge contributes to greater gains in student knowledge, but empirical evidence in support of this assumption is scarce. Using a U.S. sample of 79 biology teachers and their 2749 high school students, we investigate whether teachers' subject matter knowledge (SMK) and…

In the United States, research on beginning science teachers provides little guidance regarding empirical minimum levels of discipline-specific science coursework for sufficient subject matter knowledge to teach science. Accordingly, in this study we analyzed secondary physical science teachers' science coursework for subject matter knowledge…

Individuals hold different epistemic beliefs at different ages, and these beliefs can affect a wide range of reasoning tasks. The present study examined Chinese secondary school students' epistemic beliefs at different grade levels, and how these related to the students' abilities to identify various forms of fallacy with the use of a…

The relationship between enactment of Common Core State Standards-Mathematics (CCSSM), student misconceptions, student achievement and teacher variables was investigated. After providing professional development on CCSSM enactment, observations were conducted to determine the degree of enactment of CCSSM content and Standards for Mathematical…

This study involves the development of a three-tier diagnostic test to measure high school students' understanding of states of matter concepts. The States of Matter Diagnostic Test (SMDT) is a 19-item three-tier diagnostic test consisting of three-tier items for assessing students' understanding of states of matter concepts. The SMDT was…

Investigators have identified a number of factors that increase risk for physical and psychological dating abuse perpetration during adolescence, but as yet little is known about the etiology of sexual dating aggression during this critical developmental period. This is an important gap in the literature given that research suggests that patterns…

In this paper we report the results from a study that assessed confidence together with scales measuring self-belief--i.e., self-efficacy, different kinds of self-concepts, and anxiety--among the 15-year old students from Singapore. A distinct confidence factor was identified in the domains of mathematics (N = 1940) and English (N = 1786). Our…

This study was conducted to (a) explore high achieving high school students' perceptions of the teaching profession, (b) examine the influence of these perceptions on intentions to teach, and (c) test a recruitment suite of tools to determine the effectiveness of recruitment messaging and strategies. The Theory of Planned Behavior (TPB)…

In this study, students' understanding of chemical changes was investigated in relation to four individual differences, related to logical thinking, field dependence/independence, convergence and divergence thinking. The study took place in Greece with the participation of students (n = 374) from three grades (8th, 10th and 12th grades) of…

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…

Choosing a college is one of the first important decisions that many young adults undertake. Popular media suggests how students should find an appropriate college based on traditional practices (Hallet, 2008; Kulman, 2007), yet, many aspects of the reality experienced by new kinds of students and colleges is largely ignored in the college choice…

Recent policy changes have facilitated an expanded role for VET in Schools in supporting school completion, with vocational education and training (VET) in schools qualifications and subjects receiving increasing recognition in senior secondary certificates. Despite increased attainment of VET qualifications amongst 15 to 19-year-olds (Australian…

A large scale study involving 1786 year 7-10 Korean students from three school districts in Seoul was undertaken to evaluate their understanding of basic optics concepts using a two-tier multiple-choice diagnostic instrument consisting of four pairs of items, each of which evaluated the same concept in two different contexts. The instrument, which…
