This study investigates the effect of E-learning (EL), blended learning (BL) and flipped learning (FL) approaches on the mathematics achievement, self-regulation and mathematics self-efficacy. Participants consist of 163 first-year students attending an associate degree program (a 2-year program) of a state university. The EL, BL and FL settings…

This study investigated the application of item response theory (IRT) to expand the range of ability estimates for gifted (hereinafter referred to as high-achieving) students' performance on an above-level test. Using a sample of fourth- to sixth-grade high-achieving students (N = 1,893), we conducted a study to compare estimates from two…

The purpose of this study was to examine whether components of the Planning, Attention, Simultaneous, and Successive (PASS) processing theory of intelligence predict reading and mathematics proficiency in a group of intellectually gifted children. One hundred forty-two intellectually gifted children (70 females, 72 males; M[subscript…

Although the root-mean squared deviation (RMSD) is a popular statistical measure for evaluating country-specific item-level misfit (i.e., differential item functioning [DIF]) in international large-scale assessment, this paper shows that its sensitivity to detect misfit may depend strongly on the proficiency distribution of the considered…

The purpose of this mixed-methods study was to investigate whether blended learning increased student achievement in middle schools at a public charter school system. Qualitative data was gathered through classroom observations (N=8), teacher interviews (N=8), and student focus groups (N=6). Quantitative analysis involved a…

Data analysis is a significant methodological component when conducting quantitative education studies. Guidelines for conducting data analyses in quantitative education studies are common but often underemphasize four important methodological components impacting the validity of inferences: quality of constructed measures, proper handling of…

This study aims to investigate the effects of educational games, while teaching the unit of matter and heat, utilized on students and the remarks of the students on the process. The research model called mixed method, in which both quantitative and qualitative research methods are used together, had been applied. The research group consisted of…

The assessment of screening accuracy and setting of cut points for a universal screener have traditionally been evaluated using logistic regression analysis. This analytic technique has been frequently used to evaluate the trade-offs in correct classification with misidentification of individuals who are at risk of performing poorly on a later…

Inquiry-based science instruction is widely advocated, but studies based on international large-scale assessments often show inquiry to be negatively associated with achievement. We re-examine this issue by examining whether the association between inquiry and learning depends upon the provision of teacher guidance. Participants were 151,721…

This study determined the psychometric properties of the Economics Achievement Test (EAT) using Item Response Theory (IRT). Two popular IRT models namely, one-parameter logistics (1PL) and two-parameter logistics (2PL) models were utilized. The researcher adopted instrumentation research design. Four research questions and two hypotheses were…

Over the past two decades, researchers consistently demonstrated the importance of science teaching approaches and student self-efficacy in influencing their science achievement. These findings have become the foundation of science education reform. However, empirical supports of these relationships are limited to direct relationships and…

Math anxiety negatively predicts young children's math achievement. While some researchers have suggested that math anxiety may stem from poor math ability, others have argued that math anxiety occurs at all levels of math ability. An important question is whether math anxiety predicts math achievement over and above foundational math skills. We…

As the coronavirus (COVID-19) pandemic closes schools across the nation, education systems are scrambling to meet the needs of schools, families, and 55.1 million students. The economic impacts and trauma of recent events will also have far reaching effects that will likely exacerbate long-standing opportunity gaps. While it is difficult to…

We investigated the dimensionality of various indicators of reading prosody, and the relations of word reading and listening comprehension to the identified dimension(s) of reading prosody, using longitudinal data from Grades 1 to 3. A total of 371 English-speaking children were assessed on oral text reading, word reading, and listening…

With rising importance of collaborative problem-solving skills (CLPS) for the new information age, the PISA 2015 assessed students' CLPS skills on a large scale. This new attempt to measure CLPS raises an issue of validity. The purpose of this research is to examine evidence for convergent validity of CLPS through investigating the relationships…
