We investigated two research questions: which students are more likely to respond inconsistently to mixed-worded questionnaire scales, and which country samples have larger shares of inconsistent respondents? We defined an inconsistent response as strongly agreeing or disagreeing with both positively and negatively worded items of the same scale.…

The purpose of this quantitative, causal-comparative study was to determine the extent to which a statistically significant difference existed in eighth-grade English-language arts (ELA) and mathematics achievement between groups of students of low socioeconomic status (SES) who participated in a Washington school district's one-to-one laptop…

Cross-sectional studies such as TIMSS can reveal associations between teaching practices and student achievement that are against expectations with the theory of Educational Effectiveness Research. Therefore, this paper extends TIMSS 2019 study into a follow-up approach examining what is the contribution of TIMSS educational assessment in Teacher…

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…

Purpose: This study aimed to evaluate the stability of phonological awareness (PA) and language achievements between kindergarten and first grade among Arabic-speaking children. Method: A total of 1,158 children were assessed in PA and language skills in both grades and were classified based on distinct and integrated achievements on PA and…

This study analyzed performance, process, and survey data of eighth graders with learning disabilities (LDs) who took the 2017 National Assessment of Educational Progress (NAEP) digital math test. Compared with students with LDs who did not receive extended time accommodations (ETAs), students with LDs who received and used ETA scored…

This dissertation consists of three papers about quantitative research methods in education. Each paper is a response to potential limitations of the current approach to building evidence for effective education -- an approach that is dominated by Randomized Controlled Trials of school programs, with mathematics and English achievement as primary…

Background: Many studies have examined which kindergarteners' skills best predict reading acquisition later at school. Most of these studies focused on emergent literacy skills such as letter knowledge, phonological awareness, and oral language abilities as the basis for reading acquisition. Additionally, several studies have also found cognitive…

Understanding factors that influence children's participation in sport and physical activity is critical to designing more appealing youth opportunities and programmes. Whole-of-school initiatives offer one way to promote children's physical activity, but little is understood about how celebration within these initiatives influences children's…

The problem that was the focus of this study is that only half of the students entering kindergarten in the United States are considered kindergarten ready. This problem is important because children who are successful in kindergarten are more likely to continue to be successful in elementary school. The purpose of this basic qualitative study was…

This study examined the relationships among home-based parental involvement, study habits, and academic achievement using structural equation modeling. The sample consisted of 566 eighth-grade students in Taiwan, and their mean age was 14.35. The data for home-based parental involvement and study habits was collected in the "first survey…

We provide causal estimates of the effects of delayed kindergarten entry on achievement outcomes by exploiting a policy change in the birthdate enrollment cutoff in North Carolina that forced children born in a six-week window to redshirt. Using multiple peer group comparisons, we identify impacts on achievement and gifted or disability…

Background: Exergames are a new socio-technological phenomenon consisting of digital motor games that aim to stimulate players' motor skills. The physical-motor component of exergames has been well studied, but knowing more about their possible psychological effects in the school context is interesting to promote physical exercise practice.…

This study examines whether family income in early childhood is related to achievements of Israeli students in standardized tests at primary school. We analyzed data from the Israeli censuses of 1995 and 2008, which include information on family income and socio-economic background of children along with data pertaining to their achievements in…

This research aimed to determine the effectiveness of applying instructive simulation experiments (SE) to the development of deeper conceptual understanding, retention of static electricity contents, and engagement of 4th-grade students. The correlation between student achievements and engagement was examined. 76 4th graders (10-11 years) were…
