The present study uses a parent-offspring adoption design to examine the dual roles of heritable and environmental influences on children's mathematics achievement. Linked sets (N = 195) of adopted children, adoptive parents, and birth parents each completed a measure of mathematics fluency (i.e., simple computational operations). Birth parent…

The aim of this study was to examine the moderator role of gender and socioeconomic status (SES) factors in the relationship between students' metacognitive skills and reading performance. The sample of the study was 6890 students in the age group of 15 years-old who participated in the Programme for International Student Assessment (PISA) in 2018…

The aim of this study is to develop and apply a rubric to evaluate the solutions proposed for questions about electromagnetic induction belonging to university second year pre-service teachers. In this study which has pretest-posttest quasi-experimental design with control group, teaching of the topic of electromagnetic induction was applied to…

In the current socio-health situation, new educational challenges have emerged, such as the need to implement a virtual tutorial action. Therefore, this study has three objectives: (1) to investigate the level of digital competence that early childhood and primary school teachers possess to carry out quality online tutorial actions; (2) to analyse…

Complex research questions often need large samples to obtain accurate estimates of parameters and adequate power. Combining extant data sets into a large, pooled data set is one way this can be accomplished without expending resources. Measurement invariance (MI) modeling is an established approach to ensure participant scores are on the same…

Governments around the world use grant and loan programs to ease the financial constraints that contribute to socioeconomic gaps in college completion. A growing body of research assesses the impact of grants; less is known about how loan programs affect persistence and degree completion. We use detailed administrative data from Chile to provide…

Previous research shows that the direction of rating scales can influence participants' response behavior. Studies also suggest that the device used to complete online surveys might affect the susceptibility to these effects due to the different question layouts (e.g., horizontal grids vs. vertical individual questions). This article contributes…

This research aimed at 1) studying the second-year university students' achievement after using animated videos through Google Sites to enhance socio-culture of native English-speaking countries, 2) examining the efficiency of animated videos with an efficiency criterion of 75/75, and 3) exploring the students' level of satisfaction after using…

Many researchers have separately developed instruments to measure environmental characteristics such as attitudes, values, and knowledge. However, there is no instrument used to measure all these aspects in one comprehensive instrument. This study is meant to develop and validate a green character instrument which reveals student behavior and…

Purpose: This study aims to better understand the relationship between peer feedback in the context of online collaborative note-taking and how comments impacted student performance and understanding. Design/methodology/approach: This one sample investigation was of graduate students participating in an academic writing class working…

The study investigated the effect of using a design thinking teaching method on male and female students' achievement in some selected secondary school physics concepts in the context of STEM learning. The study was carried out in an afterschool environment which necessitated the researcher using a single group quasi experimental research design…

The structure of many science programs at the college level assumes that students are able to draw on and integrate ideas from multiple disciplinary contexts. However, most assessment tools focus on learning in the context of a single discipline. We describe the development and validation of an instrument to measure how well students are able to…

Do grade configurations affect student academic performance? To bring new evidence to this question, I use recent district-by-grade data for nearly the entire United States that contain measures of test score achievement and rates of school switching induced by grade configuration. Past research has found that student performance, is, on average,…

This study assesses the performance of Turkish science pre-service teachers (PSTs) in a TPACK-Practical Course that consists of the training course and lesson-plan-micro-teaching stages. The subjects of the study were 46 PSTs (19 males and 27 females). In this study, after PSTs took a TPACK training course, they created a TPACK-based lesson plan…

In an effort to investigate the factors that lead to success in general chemistry, the Math-Up Skills Test (MUST) and common questions were used along with a student characteristic questionnaire. The MUST is a 20-item instrument to measure mathematics fluency, which is done without a calculator with a 15-min time limit. It has been shown as a…
