It is well known that fraction knowledge is relevant for later success in mathematics. However, many students still face difficulties when dealing with fractions. Predictors of fraction knowledge have been widely examined. Systematizing "mathematical" predictors, whether their predictive contributions are direct or indirectly mediated…

Given the scarcity of studies explicitly exploring the often tacit assumption that teachers' content knowledge (CK) is pre-requisite of pedagogical content knowledge (PCK), in this study, we draw on Shulman's conceptualization of these notions to examine their relation by content-aligning the CK and PCK measures. Toward this end, we analyzed data…

The process of becoming an expert teacher, which is one of the career steps of teachers, and the evaluation of this process are important and necessary in terms of education. The general purpose of this study is to obtain the opinions of primary school teachers about the Expert Teacher Training Program Seminar (ETTPS). In the study, a qualitative…

One of the most important qualities of learners is the ability to conduct research. Students who grasp this subject acquire critical thinking abilities, which will eventually help them to function a valuable human being in the future. Proficiency in doing research is a prerequisite for academic achievement. The purpose of this study is to assess…

The implementation of geospatial technologies in both primary and secondary education is more than desirable. However, many obstacles stand in the way. This paper reflects on the current state of geographic information systems (GIS) implementation in the educational curriculum in Czechia in comparison with an international context. The study aimed…

This dissertation study investigated the efficacy of a multi-component intervention package delivered via an online learning tool on math fluency for prerequisite algebra skills for three 6th-grade students. Students were referred by their math teacher due to concerns with academic performance. Target skills were individualized for each student…

Purpose: Implementing STEM education in the early grades is a more effective way to encourage creativity, problem-solving, and innovation. There is a need for elementary teachers to implement STEM education to integrate and contextualize science, technology, engineering, and mathematics (STEM) in their teaching. This research aims to examine the…

Background: Women and under-represented minority (URM) students continue to be under-represented in STEM and earn the lowest proportion of undergraduate engineering degrees. We employed a mixed methods research approach grounded in social capital theory to investigate "when" they first consider pursuing engineering as a college degree…

Teaching students in upper elementary school to revise their papers effectively requires a three-pronged approach. First, teachers provide instruction on a relevant genre or writing form (using the Common Core State Standards for English language arts or other relevant standards as a guide). Second, teachers help students to use four basic…

The purpose of this research is to determine the requirements of being a school principal and investigate the pre-service trainings of primary and middle school principals in the United States. In accordance with this aim, semi-structured interviews were conducted with 16 primary and middle school principals from the state of Michigan. In this…

In a 9-month training experiment, 64 first graders with a risk factor were randomly assigned to computer-assisted structured discovery of the add-1 rule (e.g., the sum of 7 + 1 is the number after "seven" when we count), unstructured discovery learning of this regularity, or an active-control group. Planned contrasts revealed that the…

Noveck (2001) argued that children even as old as 11 do not reliably endorse a scalar interpretation of weak scalar terms ("some", "might", "or") (cf. Braine & Rumain, 1981; Smith, 1980). More recent studies suggest, however, that children's apparent failures may depend on the experimental demands (Papafragou…
