The level of arithmetic knowledge of a high school student was explored when solving additive word problems considering the semantic structure and syntactic component. The methodology was qualitative and developed in four stages: the first is the selection of the participant, the second is the design of a questionnaire with twenty additive…

This study draws on a research project where a model of fiction-based ethics education was developed and put into practice during a school year in five classes in compulsory school, two in grade 5 and three in grade 8. A test was constructed with the purpose of evaluating a multi-dimensional ethical competence. The test was given at the beginning…

Previous literature reported that Black students receive out-of-school suspensions (OSSs) and expulsions at disproportionately higher rates and have lower test scores than White students. This study provides recent evidence on the relation between racial disparities in discipline and in achievement, with particular focus on achievement gains, in…

We discuss an original study and two replications conducted over 18 years examining the impact of Teacher Study Group (TSG) in Vocabulary, a professional development (PD) approach for improving pedagogy and student learning. Study 1 focused on the design and development of the PD and included a small-scale randomized controlled trial to assess the…

Grade retention is one of the most discussed and controversial educational measures, and yet, it is still widely applied in many countries. Research investigating the effects of grade retention on students' psychosocial variables presents mixed findings, partly due to the variables assessed, methodological issues, and the length of the studies.…

Although there has been extensive research on students' understanding of the particulate nature of matter (PNM), there is still a lack of research on contexts that can be used to teach this challenging topic. In a previous design-based research study, the authors developed a teaching-learning sequence (TLS) on the PNM in the context of crystal…

To encourage students' self-regulated learning at home, developing skills for textbook use to overcome learning-related impasses is crucial. This study examined the effects of providing mathematics class sessions that combined teacher instruction on appropriate textbook use with peer instruction, aimed at promoting students' spontaneity and…

Objectives: Limited research exists on how new computer science (CS) teachers understand fundamental Internet principles. This knowledge gap hinders the development of effective upskilling courses, especially as new CS curricula are being introduced worldwide. This study investigates new CS teachers' conceptions of fundamental Internet principles,…

This study aims to determine the cognitive structures of students at different educational levels (8th grade and 12th grade) related to acid-base chemistry. The research was designed as a case study and structured in two stages. The first stage analyzed concepts related to acid-base chemistry and their direction and strength in students' knowledge…

The aim of this study is to examine the effect of mobile learning supported science teaching on eighth grade students' Science, Technology, Engineering and Mathematics fields and Information Technologies Self-Efficacy and to determine students' views on this process. For this purpose, a quasi-experimental design with pre-test post-test control…

One of the main objectives of international large-scale assessments is to make comparisons between different countries, education policies, education systems, or subgroups. One of the main criteria for making comparisons between different groups is to ensure measurement invariance. The purpose of this study was to test the measurement invariance…

Five groups rank state charter school environments according to their laws, regulations, funding, and other characteristics, but none rank states by charter student performances on a national test. We rank states by demographically adjusted math and reading performances of charter students in 4th and 8th grade for the period 2009 to 2019 on the…

Also known as The Nation's Report Card, the National Assessment of Educational Progress (NAEP) is the largest nationally representative and continuing assessment of student achievement and their learning experiences in various subjects for the nation, states, and 27 urban districts. The National Center for Education Statistics (NCES) is currently…

The purpose of this quantitative ex post facto study was to determine if, and to what extent, differences existed in pre-and-post math scores following the VMath intervention for Title I 6th, 7th, and 8th graders in the Southwestern United States. Three research questions guided this study: (1) is there a statistically significant difference in…

This study aimed to develop characteristics of the Genre-Based approach (GBA) via the Miro platform and to discover results on using this approach and the Gathering, Processing, Applying, and Self-Regulating (GPAS) process. The study employed experimental research using a true group pretest-posttest control group design with Grade 8 students…
