To ascertain whether lecturers had the pedagogical competency skill needed in impacting students with necessary skills they need outside school, this study developed a scale to measure Lecturers' Pedagogical Competence (LPCS) in universities using item response theory. The pedagogical competence of university lecturers was assessed using a set of…

There is dearth of research in happiness among Africans, because of no indigenous scale among the plethora of scales used in measuring happiness. Consequently, an indigenous happiness scale was conceived using a three stage method (stage 1 = 48, stage 2 = 408, stage 3 = 1468 participants). A sequential mixed method approach and cross sectional…

In this research, we aimed to adapt the Xenophobia Scale developed by Olonisakin and Adebayo (2021) into Turkish. We conducted research on two separate study groups comprising 563 teacher candidates. Before starting the adaptation process of the scale, we obtained necessary permissions from the authors, who developed the original form. When…

Informant-report measures for screening symptoms of autism spectrum disorder (ASD) and other neurodevelopmental disorders (NDDs) are needed for low-resource settings if early identification is to be prioritized because early developmental concerns are likely to be expressed by parents and other caregivers. This paper describes the initial…

In the use of English programme of the general studies unit of Nigerian universities, computer based testing (CBT) has been introduced as a novel approach for writing examinations, as against the paper based test (PBT). For this reason, there is a need to ascertain students' perceptions of computer-based tests in the use of English Programme,…

This paper describes a study that focused on developing, validating and standardizing a dyscalculia test, henceforth called the Dyscalculia Test. Out of the 4,758,800 students in Nigeria's upper primary and junior secondary schools, I randomly drew a sample of 2340 students, using a multistage sampling procedure that applied various sampling…

Research has assessed the diverse characteristics of principals and teachers in analysing students' educational outcomes at various levels. However, these studies often focus on the cognitive domain of learning, ignoring the affective and psychomotor aspects. Bridging this gap, we used hierarchical linear regression to link two inputs of teachers…

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 determined the psychometric properties of the Economics Achievement Test (EAT) using Item Response Theory (IRT). Two popular IRT models namely, one-parameter logistics (1PL) and two-parameter logistics (2PL) models were utilized. The researcher adopted instrumentation research design. Four research questions and two hypotheses were…

The research focused on development, validation and standardization of a diagnostic instrument called Tertiary Examination Behaviour Inventory (TEBI) for determining the tendency of students in tertiary institutions to participate in academic cheating. Anchored on the Modified Theory of Planned Behaviour (MTPB) and Item Response Theory (IRT), the…

The study investigated Problem-based Instructional Strategy and Numerical ability as determinants of Senior Secondary Achievement in Mathematics. This study used 4 x 2 x 2 non-randomised control group Pretest-Posttest Quasi-experimental Factorial design. It consisted of two independent variables (treatment and Numerical ability) and one moderating…

The purpose of the study was to construct and validate a Physics Aptitude Test (PAT) for senior secondary schools. The test was designed primarily as an assessment tool for senior secondary school students who have aptitude for Physics. Four research questions guided the study. It was an instrumentation study designed to produce an assessment tool…

Computer-based assessment or e-assessment system is an e-learning system where information communication technology is utilized for examination activity, grading, and recording of responses of the examinees. It includes the entire assessment process from the examinees, teachers, institutions, examination agencies, and the public. E-assessment…

This study concerned validating academic integrity survey (AIS), a measure developed in 2010 to investigate academic integrity practices in a Malaysian university. It also examined the usefulness of the measure across gender and nationality of the participants (undergraduates of Nigerian and Malaysian public universities). The sample size…

This study was aimed at the development of an instrument for measuring students' attitudes towards mathematics. A survey research design was adopted involving 510 students randomly selected. Exploratory factor analysis (EFA) was carried out to determine the number of factors to be retained in the ATMS. The adequacy of the sample was confirmed by…
