The present study investigated the role of disciplinary climate in the classroom and student math self-efficacy on math achievement. The student part of the Program for International Student Assessment (PISA) 2003 survey containing 4,199 U.S. observations was employed in a weighted least squares nested multiple regression framework to predict math…

The science vocabulary from a science curriculum standards document (Ministry of Education Ontario, 2007) was classified by morphological developmental level and compared to the grade level topics of the curriculum (grades 1 to 8). Descriptive statistical analyses highlight the complex nature of science vocabulary and the incompatibilities between…

In this paper we explore some of factors that affect bilingual students' comprehension of story problems: vocabulary, syntax, cultural relevance and understanding of the word problem genre. In an effort to determine how these factors interact, we asked 18 Spanish/English bilingual children to retell and solve arithmetic story problems in…

The aim of this paper is to examine the impact of activity-based mathematics instruction on mathematics performance and investigate those factors, which contribute to the mathematics performance of a sample of children aged between 10 and 12 years. The study was designed to consider the impact of prior knowledge, self-regulation, prior attitude,…

The classroom practices of science teachers are indicative of their beliefs and pedagogical content knowledge (PCK). PCK is an amalgam of knowledge about subject matter, pedagogy, and contextual issues. This article identifies areas where physics teachers in Lesotho may need professional development support by addressing the research question: How…

This paper reports a qualitative research that identifies the characteristics of good mathematics teaching from the perspective of Mexican high school students. For this purpose, the social representations of a good mathematics teacher and a good mathematics class were identified in a group of 67 students. In order to obtain information, a…

Knowledge is not simply a collection of facts, principles, and formulas; instead, meaningful knowledge is organized around core concepts that guide peoples' thinking about a subject. Therefore, knowledge organization is recognized as an important component of understanding learning and teaching. In this research, knowledge organization of two…

In this study, the Trends in International Mathematics and Science Study 2007 data were used to build mathematics achievement models of fourth graders in two East Asian school systems: Hong Kong and Singapore. In each school system, eight variables at student level and nine variables at school/class level were incorporated to build an achievement…

In this study, we investigated elementary student teachers' scientific habits of mind for a series of socioscientific issues, and compared their views with respect to academic performance and type of programme. The sample consisted of 1,600 student teachers from science education, mathematics education, primary teacher education and social…

We compared the materialization of knowledge integration processes in class discussions that followed troubleshooting (TS) and problem-solving (PS) tasks and examined the impact of these tasks on students' conceptual understanding. The study was conducted in two sixth-grade classes taught by the same teacher, in six lessons that constituted a…

The aim of the study was to discover the contribution of students' interest in school biology, as well as their self-efficacy and attitudes towards different science subjects and mathematics when explaining students' orientation towards biology-related careers at upper-secondary school. The data of 321 K-11 students (49% women) were…

For over two decades, there has been increasing concern regarding the science learning of disadvantaged students such as indigenous or disabled students. The academic achievement of students with hearing impairment has been seen as relatively low. This low achievement has been mainly due to students' poor literal ability and not because of…

This study used phenomenography, a qualitative method, to investigate Taiwanese mathematics teachers' conceptions of school mathematics, school statistics, and their differences. To collect data, we interviewed five mathematics teachers by open questions. They also responded to statements drawn on mathematical/statistical conceptions and…

Informal place-based environmental education is a proven approach for increasing environmental awareness for students in urban cities. This article describes and qualitatively evaluates the first two academic years of the EnvironMentors program at Louisiana State University (LSU-EM), which is part of a national network of EnvironMentors programs.…

This article investigates the influences on a teacher's uncertainty through the use of storyline methodology. As a research method, storylines can be utilised to educe a teacher's responses to inquiries into their practice. The particular storylines in this article are drawn from the uncertainty work of Floden and Clark (1988) and…
