In order to have a better understanding of the nature of reading behavior, it is quite essential to scrutinize the underlying assumptions of the two competing theories: the componential approach and unitary hypothesis and see how this is reflected on testing the reading skills. As a result, the current study was aimed at broadening the existing…

Artificial neural networks (NN) can help researchers estimate propensity scores for quasi-experimental estimation of treatment effects because they can automatically detect complex interactions involving many covariates. However, NN is difficult to implement due to the complexity of choosing an algorithm for various treatment levels and monitoring…

This study aims to compare normality tests in different sample sizes in data with normal distribution under different kurtosis and skewness coefficients obtained simulatively. To this end, firstly, simulative data were produced using the MATLAB program for different skewness/kurtosis coefficients and different sample sizes. The normality analysis…

We derive formulas for the differential item functioning (DIF) measures that two routinely used DIF statistics are designed to estimate. The DIF measures that match on observed scores are compared to DIF measures based on an unobserved ability (theta or true score) for items that are described by either the one-parameter logistic (1PL) or…

The characteristic curve methods have been applied to estimate the equating coefficients in test equating under the graded response model (GRM). However, the approaches for obtaining the standard errors for the estimates of these coefficients have not been developed and examined. In this study, the delta method was applied to derive the…

In many large testing programs, equipercentile equating has been widely used under a random groups design to adjust test difficulty between forms. However, one thorny issue occurs with equipercentile equating when a particular score has no observed frequency. The purpose of this study is to suggest and evaluate six potential methods in…

Online misinformation is a pervasive global problem. In response, psychologists have recently explored the theory of psychological inoculation: If people are preemptively exposed to a weakened version of a misinformation technique, they can build up cognitive resistance. This study addresses two unanswered methodological questions about a widely…

Every year, several teachers retire from the education sector in Rivers State and these teaching retirees still have a lot they can contribute to the education system but can only deliver lifelong educational services when life after retirement is patterned to what is obtainable during active service. The study investigated teaching retirees' life…

This study aims to investigate how social media tools, in other words social network services (SNS), affects the success of Japanese language learners in learning Japanese culture in undergraduate programs. For this research, a mixed method approach was used with a quantitative, quasi-experimental research design including a pre-test-post-test…

School climate is theoretically important for the academic achievement of students in urban schools because safety and support at school may compensate for negative structural forces experienced elsewhere. There is strong evidence for an association between school climate and student achievement, but little suggests the association's…

There is a strong and growing focus on self-determination in French-speaking countries, and this pilot study reports the technical adequacy of the Self-Determination Inventory: Student Report (SDI:SR) French Translation. Data were collected with 471 French-speaking youth with and without disabilities in Canada (Quebec), Switzerland, France, and…

This study evaluated the effects of a comprehensive school-based sexuality education programme in enhancing sexual health knowledge and understanding among adolescents, parents and school personnel in six secondary schools in Hong Kong. Study outcomes were evaluated through pre- and post-tests. A total of 1588 students, 40 parents and 271 school…

Students entering high school often bring misconceptions about the nature of science and experimentation with them from middle school. Many also bring a belief that they are not a "science kid" and, therefore, cannot be a strong student in Biology. This belief can lead to a lack of self-efficacy and of student agency in the classroom.…

The purpose of this study is to develop a nonparametric DIF method that (a) compares focal groups directly to the composite group that will be used to develop the reported test score scale, and (b) allows practitioners to explore for DIF related to focal groups stemming from multicategorical variables that constitute a small proportion of the…

Teacher competency is crucial for the quality development of learners. Teachers with high competence in learning management will result in high-quality learners. This research aims 1) to study the components and indicators of teachers' competency in teaching railway control and maintenance. 2) to study current conditions, desirable conditions,…
