Research has demonstrated strong relations between spatial skill and mathematics across ages and in both typical and atypical populations, suggesting that a significant proportion of variance in mathematics performance can be explained by variance in spatial skill. Why do these relations exist and how do they develop? Studies of dimensionality in…

This study explores six item-reduction methodologies used to shorten an existing complex problem-solving non-objective test by evaluating how each shortened form performs across three sources of validity evidence (i.e., test content, internal structure, and relationships with other variables). Two concerns prompted the development of the present…

Through their work on the Fractions Project, Steffe and Olive (2010) identified a progression of fraction schemes that describes students' development toward more and more sophisticated ways of operating with fractions. Although several quantitative studies have affirmed this progression, the question has remained open as to whether it is specific…

Why is the use of letters in algebraic expressions and equations--variables--the source of such uncertainty for students and teachers? The authors studied a sixth-grade classroom and observed that students hold many misconceptions about variables. Some students hold an algebraic view of the equal sign. For them, it indicates an equation and…

While we have known about the benefits of project-based learning for decades, it has been difficult to maintain momentum in learning how to do it well, especially as the policy context in education turned toward high-stakes accountability measures in the early 2000s. Currently, many schools across the country are incorporating project-based…

This paper is a description of a proposed action research study driven by a problem of practice. The problem for this action research is that the teacher-researcher's sixth-grade social studies students lack critical thinking skills. Critical thinkers are engaged and creative learners who analyze complex issues and challenges within society. The…

Noting the lack of resources to meet face-to-face, most notably time, a significant body of research has investigated the use of computer-mediated communication (CMC) to replace face-to-face interactions of teacher professional learning communities (PLCs). Equally noted is the research on social constructivist theory that supports social…

In a case study conducted in a biology class in Slovenia, six grade students participated in a biology project Writing Versus Typing in a Biology Class. The final task in this project was to write a chapter for a biology textbook with the title Urtica dioica. The task was performed twice: firstly, the text was written by the hand and secondly it…

Relevant teacher qualifications that include specialist knowledge and knowledge in didactics significantly influence the level of achievement of education goals during the teaching process. Teacher's perception of their own professional competence to teach may depend on their qualification which is linked to the education obtained. The purpose of…

The purpose of this mainly descriptive study was to investigate teachers' perceptions about how they teach writing as well as their beliefs about preparation and efficacy to teach this skill. It also examined if preparation and efficacy beliefs along with teaching experience (years teaching the language arts) predicted teachers' reported writing…

The aims of teaching have evolved along with the society in which we live, from a teaching based in memory to a one that teaches to reason, in order to adapt to the accelerated rate of change imposed by the application of scientific discoveries in our society. We have a society in continuous learning, which requires the ability to reason in order…

To better understand STEM interest development during adolescence in an urban community, we examined how "STEM Interested" youth differed from disinterested youth and how interest changed over time from age 11/12 to 12/13. We surveyed youth to measure interest in four components of STEM, used cluster analysis to categorize youth based on…

The main purpose of the current study is to investigate middle school students' math self-efficacy perceptions and math problem posing attitudes. The sample of the study is comprised of 990 fifth, sixth, seventh and eighth grade students attending middle school in the Fethiye district of the city of Mugla. As the data collection tool, the…

In this study, a new model termed as "Flexible Inquiry Based Science Teaching", which is developed using the framework of the inquiry approach is proposed. Science teachers (n=2) who participated in the study were instructed on the inquiry approach and their in-class activity applications were examined. The "electricity module"…

The aim is to analyse how policy decisions about assessment practices influence what it means to be a student in a performative system. We examine an occasion where a previously mandatory national test became optional, and how students took the opportunity to try to change the school's decision about this. The study is based on student group…
