This study is a descriptive survey model which aims to reveal the measurement estimation abilities of secondary school students. The sample of the study consisted of 91 secondary school students at 5th, 6th, 7th and 8th grades in the province of Adana. Measurement estimation ability test was used as the data collection tool. This test is comprised…

The effectiveness of class size reduction on student performance has been of great research interest and policy debate worldwide. Nevertheless, the evidence has been largely inconclusive partially due to potential bias arising from non-random placement of students and teachers in classrooms of different sizes. This study applied instrumental…

This study utilized a one-group pretest-post-posttest design (Allen, 2017) to examine the effects of the Hands-On Equations system on students' abilities to solve multi-step equation problems following explicit classroom instruction on the skill. Participants consisted of four middle-school male students, all of whom received special education…

There is an increasing interest of policies and projects to adapt boarding schools as a means to provide quality education for educationally disadvantaged students. However, little evidence is available for the effectiveness of boarding schools. The current study examined the boarding effect on primary and middle school student mathematics…

Using the International Association for the Evaluation of Educational Achievement's (IEA's) Trends in International Mathematics and Science Study (TIMSS) 2015 data, this brief explores the relationship between teachers' gender and students' mathematics and science achievement, as well as gender differences in science and mathematics teachers'…

The National Center for Education Statistics (NCES) has periodically published reports using results from the National Assessment of Educational Progress (NAEP) to compare the proficiency standards that states set for their students. Since standards vary across states, the results of the various state assessments cannot be used to directly compare…

In this exploratory study, I investigate the relationship between age, knowledge, and creativity in mathematics, by looking at to what extent does grade level, controlled for mathematical achievement, influence mathematical creativity and what characterizes the relationship between grade level, mathematical achievement and mathematical creativity.…

The purpose of this study was to investigate the tessellation performance of 8th-grade students and factors affecting their performance. Student performances have been examined in two dimensions: identification and completion of tessellation. In this context, a diagnostic test containing two main questions with the content of determining whether…

This study aims to compare the performance of different small sample equating methods in the presence and absence of differential item functioning (DIF) in common items. In this research, Tucker linear equating, Levine linear equating, unsmoothed and pre-smoothed (C=4) chained equipercentile equating, and simplified circle arc equating methods…

Research on learning through serious games has been gaining importance in recent years. We develop the serious game "Tempoly," concerning the learning of the four arithmetic operations on polynomials. A quasi-experimental study was carried out with 95 students of 8th grade, to evaluate the reactions of the students to the game, the…

The study tested the hypothesis that there are sex differences in the pathways to mathematical development. Three-hundred and 42 adolescents (169 boys) were assessed in various mathematics areas from arithmetic fluency to algebra across 6th to 9th grade, inclusive, and completed a battery of working memory, spatial, and intelligence measures in…

Understanding the structure, antecedents, and outcomes of students' emotions has become a topic of major interest in research on mathematics education. Much of this work is based on the Achievement Emotions Questionnaire--Mathematics (AEQ-M), a self-report instrument assessing students' mathematics-related emotions. The AEQ-M measures seven…

We investigated effects of tracking students into higher, more academic, and lower, less academic, school types immediately after primary school (early tracking) instead of having a comprehensive secondary school system (late tracking) on school gender segregation and gender gaps in achievement outcomes. We assumed that, in early tracking…

According to music educators, persistence beyond a student's initial enrollment in middle and high school music is a problem; however, there has been little research to substantiate this claim. Although several recent large-scale, longitudinal studies of initial selection into music classes have been conducted, longitudinal studies on who…

This dissertation researched the scope of mathematics achievement disparities in the United States and how these disparities can be minimized through a self-efficacy lens. To answer pertinent research questions with data from the National Assessment of Educational Progress (NAEP) 2019 mathematics assessment in Grades 4, 8, and 12, gap analyses,…
