This dissertation presents an innovative approach to examining the keying method, wording method, and construct validity on psychometric instruments. By employing a mixed methods explanatory sequential design, the effects of keying and wording in two psychometric assessments were examined and validated. Those two self-report psychometric…

This study attempted to create a valid and reliable instrument to measure how gifted children perceive the gifted label and others' perceptions of giftedness. We recruited a total of 300 gifted Turkish children (59.3% males; 40.7% females) aged 10-13 years (M = 11.4, SD = 0.99) to this validity and reliability study. For validity concerns, we…

Contribution: This article contributes to the literature surrounding first-year engineering students' academic well-being by proposing a conceptual framework guiding an understanding of supportive sources that foster students' academic well-being. A survey was designed and tested accordingly, and four factors that contribute to students' academic…

During an assignment as a change leader of a complex IT change program within a Dutch public government organization, I used action learning to develop and support the desired changes and to tackle the complex problems that usually accompany such a change program. During this action learning project, I took the role of facilitator and I devised…

Highlighting the interdisciplinary nature of research, we present a series of experiments for undergraduate lab courses that teach the principles of preparative ion exchange chromatography and flame emission spectroscopy. Through these inquiry-based experiments, the students learn about experimental design and instrument limitations, naturally…

Assessment of attitudes towards statistics [ATS] is needed to support the success of statistics education in tertiary institutions, so measuring instruments with high accuracy is required. However, existing instruments to measure ATS have not considered the use of technology as an essential variable affecting success in statistics education. The…

Background: Undergraduate engineering students experiencing distress are less likely than peers to ask for professional help. A population-specific instrument to facilitate the identification of factors that influence mental healthcare utilization could guide development and testing of interventions to increase help seeking. Purpose: We used mixed…

Students in a typical instrumental analysis course may learn more than 30 analytical techniques. There are more than 150 components associated with the instrumentation that they learn. To help students organize this large amount of information, we classified these components into four categories: sources, samples, discriminators, and detectors. In…
