New statistical methods are being added to the literature as a result of scientific developments each and every day. This study aims at investigating one of these, Maximum Likelihood Score Estimation with Fences (MLEF) method, in ca-MST. The results obtained from this study will contribute to both national and international literature since there…

This study examined the relationship between students' (N = 229) concepts of size and scale and students' achievement in science and mathematics over a 3-year period. Size and scale are considered one of the big ideas in science that permeates disparate science and mathematics content areas, yet little is known about the relationship between…

This study aims to investigate the anxiety levels of secondary school students towards science course depending on a number of variables. Research sample consists of 2245 students who continue their education at public schools in Denizli (west of Turkey) in the academic year of 2017-2018. "Anxiety Scale for Science Course and "Personal…

Using data from the Early Childhood Longitudinal Study--Kindergarten cohort (ECLS-K), this study aimed to identify body mass index (BMI) trajectories from kindergarten to eighth grade using group-based trajectory modeling (GBTM), examine the relationships between BMI trajectories and adolescents' school achievement (reading and math), determine…

Background: Based on Mayer and Salovey's model of emotional intelligence, this study examined whether perceived stress mediates the interplay of emotional intelligence and life satisfaction for girls and boys during early and middle adolescence. Methods: Using multigroup structural equation modeling with questionnaire data from a sample of Spanish…

The purpose of this study was to examine middle school students' proportional reasoning, solution strategies and difficulties in real life contexts in the domain of geometry and measurement. The underlying reasons of the difficulties were investigated as well. Mixed research design was adopted for the aims of the study by collecting data through…

The purposes of our study were to develop and validate a test for measuring Korean elementary and middle school students' information and communications technology (ICT) literacy and to make suggestions for improving ICT literacy across Republic of Korea. To those ends, we conducted a literature review, consulted expert opinions, administered a…

While curriculum-based measurement (CBM) tools for screening decisions in reading, mathematics, and written language have been well examined, tools for use in content areas (e.g., science and social studies) remain in the beginning stages of research. In this study, two alternate forms of a new CBM tool (Statement Verification for Science; SV-S),…

In this study we investigated the relationship between urban eighth grade students' Hands-On Exposure to Algebraic Thinking (HEAT) competition performance and their subsequent performance on standardized measures of mathematics achievement (ACT Composite Score, ACT Math Scores, and Louisiana Algebra End of Course Exams). It was found that the…

In the literature, response style is one of the factors causing an achievement-attitude paradox and threatens the validity of the results obtained from studies. In this regard, the aim of this study is two-fold. Firstly, it attempts to determine which item response tree (IRTree) models based on the generalized linear mixed model (GLMM) approach…

In this study, the researcher examined the effectiveness of the WhyTry social skills program through the correlation of student behavioral change and improved attendance, after completing the 10 metaphor lessons over the course of a semester middle school curriculum rotation. The WhyTry program is designed to address a whole child approach rather…

In November 2018, the Australian Government announced an inquiry into the status of the teaching profession that would examine ways to ensure that the profession remains fulfilling and rewarding for educators. While the inquiry's proceedings lapsed with the calling of the federal election in April 2019, large-scale surveys do provide us with a…

Empirical findings have repeatedly demonstrated that students' motivation decreases over the course of secondary education. This decline in learning motivation is one of the top challenges nowadays and is relevant for policy, as well as research and practice. Taking this educational challenge into account, the chapter targets the following…

The need to raise achievement levels in mathematics and science has led instructional design researchers to focus on the factors that enhance achievement in these subjects. Understanding of students toward mathematics achievement may guide educators in their efforts to promote achievement by designing learning models that provide the most…

This study investigates the relationship between text-to-speech (TTS) usage and item-by-item performance in the 2017 eighth-grade National Assessment of Educational Progress (NAEP) math assessment, focusing on students with disabilities (SWDs), English language learners (ELLs), and their general education (GE) peers. Results indicate that all…
