A large-scale simulation study of the assessment effectiveness of a particular instantiation of knowledge space theory is described. In this study, data from more than 700,000 actual assessments in mathematics using the ALEKS (Assessment and LEarning in Knowledge Spaces) software were used to determine response probabilities for the same number of…

Assessment is an integral part of any teaching learning process. Assessment practices have a large number of functions to perform in the context of the teaching learning process. Do contemporary assessment practices perform these function is a critical question to be analysed. In this paper, an attempt has been made to analyse the myths and…

The author discusses valid and reliable ways to assign grades in an academic course in any discipline. "Validity" means the accuracy of a grade's reflection of student learning and achievement. "Reliability" concerns the degree of random error that might be present and affect validity. First the author defines a grade as a…

Validity is broadly defined as how well something measures what it's supposed to measure. The reliability and validity of scores from assessments are two concepts that are closely knit together and feed into each other.

Background: "How do I perceive my own body?" is a central question during adolescence, which addresses the subjective assessment of body image, called Body Esteem. Although concern about body esteem increases during adolescence, there is a lack of psychometrically validated measures to assess it specifically among Spanish adolescents.…

The multiple-choice (MC) item format has been widely used in educational assessments across diverse content domains. MC items purportedly allow for collecting richer diagnostic information. The effectiveness and economy of administering MC items may have further contributed to their popularity not just in educational assessment. The MC item format…

The present study aimed to adapt the Teacher Self-Efficacy Scale (TSES) developed by Schwarzer et al. (1999) into Italian and to test its validity and reliability. In a group of teachers (N = 683; 83% female), the factor structure (Confirmatory Factor Analyses), construct validity (latent relations with burnout variables), measurement invariance…

Higher education continues to face an uncertain future, not only through demographic shifts, rising costs, and a competitive marketplace, but also through dissonant visions for the telos of education. In this context, Christian institutions have the opportunity to carve out a distinctive niche, provide answers about the purpose of a liberal…

The purpose of this study was to better understand how middle school students consider the source of information when processing videos with conflicting information. To this end, we exposed a sample of seventh-graders to a series of videos in which two interviewees expressed divergent positions on a socioscientific issue ('Will organic farming be…

This paper explores the spatial dimension of Fleming's Left Hand Rule (LHR), commonly-used in Physics instruction for determining the direction of force using the left hand's thumb, forefinger and middle finger. A new instrument was developed to gauge students' ability to coordinate their fingers in 3D space (egocentric frame of reference) based…

Background/purpose: ChatGPT, a recent form of AI-based language model, have garnered interest among people from diverse backgrounds with its immersive capabilities. Using ChatGPT to support or generate scientific research has also created an ongoing debate over its advantages versus risks. The present study aimed to conduct an AI-enabled research…

In recent years, research has focused on the factor structure of the Teacher Sense of Efficacy Scale (TSES), and the significant effects of teachers' self-efficacy on both teachers' outcomes (teachers' performance, enjoyment of teaching, and commitment to teach), and students' outcomes (student learning achievements, motivation, and own sense of…

Research on interpersonal behaviour is becoming increasingly important in a variety of social contexts and cultures. In educational practice, its importance is based on interactions as the educational context, in which learning, value formation and meaningful activities take place. The aim of this was to adapt the Interpersonal Behaviours…

This study aims to develop a valid and reliable assessment tool for the assessment of safety skills of individuals with intellectual disabilities, examine the effectiveness of the Safety Skills Instruction Program (SSIP) in teaching safety skills to these individuals, determine the preservation of skills after instruction by observation, and…

Low cost, non-invasive instruments for the identification of high academic potential in early childhood education and care are scarce, and the complexity of cognitive development indicates that combinations of screening instruments are needed. This study investigates the reliability and validity of three instruments (individually and in…
