Data from student learning provide learning curves that, ideally, demonstrate improvement in student performance over time. Existing data mining methods can leverage these data to characterize and improve the domain models that support a learning environment, and these methods have been validated both with already-collected data, and in…

In the field of social sciences, certain tasks, such as the identification of typologies and the characterization of groups of individuals according to a set of questions, tend to pose a challenge for researchers. Further complications arise if the chosen rating scale is from 0 to 10, since the responses can be treated either as metric or…

The dimensionality of a set of items is important for scale development. In practice, tools that make use of eigenvalues are often used to assess dimensionality. Parallel analysis is featured here as it is becoming an increasingly popular method for assessing the number of dimensions, and computational tools have recently been made available which…

We surveyed high school students in Southern California to investigate whether there is an improvement in financial attitudes from eight class periods of financial literacy intervention in a high school economics course. We examine whether the money management (MM) and financial investing (FI) components of financial instruction influence…

The purpose of this study is to examine the validity of the scale for identifying gifted children, whose validity was proven by exploratory, confirmatory factor analysis, and whose reliability was proven the Cronbach alpha coefficient for identifying children in the 3-6 age group, using Mokken scaling based on nonparametric item response theory.…

This Monte Carlo simulation study aimed to investigate confirmatory factor analysis (CFA) estimation methods under different conditions, such as sample size, distribution of indicators, test length, average factor loading, and factor structure. Binary data were generated to compare the performance of maximum likelihood (ML), mean and variance…

The purpose of this study was to develop and validate a Digital Writing Scale that measures the perspectives of individuals on digital writing. A total of 615 preservice teachers studying in the faculty of education at a state university in Turkey participated in the study (n = 615). The data were collected in two phases for exploratory factor…

Internationalization and integration of the educational environment raises the issue of university lecturer development of professional mobility in Kazakhstan's higher education system. The aim of the study is to find an empirical approach to defining the factors for the development of lecturer professional mobility in the modern conditions of…

This study investigated the mediational relationship between teachers' perceived school goal structure, achievement goals and emotions in teaching. The participants were 495 Singapore teachers who took an online survey on the measured variables. We conducted structural equation modelling to test the hypothesized mediation model and found that…

The purpose of the research is to develop a valid and reliable attitude scale that can measure the attitudes of math and science teachers (315) and teacher candidates (105) towards mistakes and instant feedback. In the validity studies, the exploratory factor analysis was made with the SPS1S 8.0 package program after that the confirmatory factor…

Purpose: The aim of this study was to determine the changes in neuromuscular contractile properties in elite cyclists associated to the peripheral fatigue produced in a maximal incremental test in cycle ergometer. Methods: Forty-eight volunteers' well-trained male cyclists were evaluated during the competition season within a recovery microcycle.…

An exploration of factor analytic structure of the conceptions of mathematics scale among pre-service mathematics teachers in South-West Nigeria was conducted as evidence suggests paucity of research on psychometric properties of the conceptions of mathematics scale in Nigeria. This article through instrumentation research methodology reports the…

This study aimed to investigate cross-cultural measurement invariance of the PISA (Programme for International Student Assessment, 2015) science literacy test and items and to carry out a bias study on the items which violate measurement invariance. The study used a descriptive review model. The sample of the study consisted of 2224 students…

Cost and time constraints make it challenging to include hands-on laboratory experiences in psychology courses, yet engaging laboratory experiences can increase scientific literacy and appreciation. The present study tested whether learning by observing could also increase scientific literacy (knowledge of social neuroscience). We additionally…

This article documents the development of a questionnaire designed to measure the cultural and academic experiences (CAEQ) of East Asian research students enrolled at Australian universities. The CAEQ comprises three subscales: sense of belonging, learning strategies and perception of progress. The scale was designed based on literature studies…
