The aim of this study is to reveal the impact of Inquiry-Based Learning (IBL) on students' ability to come up with the rules of divisibility themselves and on their academic achievement in the 8th grade Mathematics course as well as to obtain students' views on the learning and teaching process, through the use of a mixed-methods sequential…

Spatial skills are critical for student success in K-12 STEM education. Teachers' spatial skills and feelings about completing spatial tasks influence students' spatial and STEM learning at both the primary and secondary levels. However, whether spatial skills and spatial anxiety differ or not between these two teacher levels is unknown.…

This study compared two goal-setting approaches found in the Precision Teaching literature, namely the minimum celeration line and the beat your personal best during the mathematical practice of three male students diagnosed with autism, aged 8-9. An adapted alternating treatments design with a control condition was embedded in a concurrent…

Teachers' understanding of the concepts they teach affects the quality of instruction and students' learning. This study used a sample of 303 teachers from across the USA to examine elementary school mathematics teachers' knowledge of key concepts underlying fraction arithmetic. Teachers' explanations were coded based on the accuracy of their…

The present study aimed to examine the opinions of in-and preservice middle school mathematics teachers about teaching four operations with integers through "number line" and/or "counters". Participants were 42 middle school mathematics teachers and 51 pre-service mathematics teachers. The data were collected through open-ended…

Gifted education needs to be constantly improved and differentiated for various types of domain-specific giftedness, especially in STEM (science, technology, engineering, and mathematics) subjects. Therefore, teachers must be adequately trained in the field of giftedness. The aim of this study was to investigate (the Big Five) personality factors…

The purpose of this study is to explore preservice teachers' (PTs') ability to implement multiple strategies using standard algorithms and alternative strategies and to investigate their conceptual knowledge of decimal operations. There were 37 PTs who participated in this study, all of whom attended a mathematics course in the K-8 Teacher…

Understanding of the differential washback effects of high-stakes tests on students' learning remains limited. This study attempts to fill this research gap by investigating the differential washback effects of the National Matriculation English Test (NMET) in China on students' English learning process across genders, grades and English…

This article presents a part of the Inter-Tetra project. This study firstly reviews the literature on conceptions of experiments in didactics of math and didactics of physics to design questionnaires to survey the conceptions of experiments in teaching physics and teaching math in Vietnam. Thereafter, the survey has been conducted among the math…

This study focuses on proportional division, a specific problem type of proportions and proportional relationships, which embeds a part-part-whole relationship. We investigated how students in grades 6 to 9 solved and perceived three proportional division problems. Analysis of the students' performance on the tasks revealed three types of…

The current study explored the difficulties teachers encounter when teaching common fractions division, focusing on teachers' knowledge concerning this issue. Nine teachers who study towards a M.Ed. degree in mathematics education demonstrated the algorithms they apply in order to solve fractions division problems, described how they teach the…

While helping students develop informed views about nature of scientific inquiry (VNOSI) has been emphasised in science education, little is known regarding students' current VNOSI at a certain grade level and whether there was evidence of higher attainment of VNOSI in students in higher grades as compared to lower grades? The purpose of this…

The employment of the mother tongue or first language (L1) in foreign (FL) or second language (L2) teaching is a controversial issue and still continues to take considerable attention from researchers. Hence, the current study attempted to shed light into the use of L1 in Turkish EFL classes. In particular, it focused on the amount and the…

In this article, we use a two-dimensional assessment to examine the experimental impacts of a mathematics learning trajectory-oriented formative assessment program on student strategies for problems involving multiplication and division. Working from the theory that the development of students' multiplicative reasoning involves improvements in…

This research aimed to investigate the requirements of the application of the STEM approach in teaching science and mathematics and the teachers' attitudes towards it. The study used descriptive approach. The study sample consisted of (159) male and female teachers chosen by the random stratified sample method from the study community represented…
