Principal Component Analysis (PCA) is a powerful statistical technique for reducing the complexity of data and making patterns and relationships within the data more easily understandable. By using PCA, students can learn to identify the most important features of a data set, visualize relationships between variables, and make informed decisions…

We conducted a component analysis of skill acquisition consequences for correct and incorrect responses. In the learn unit (LU) condition, researchers praised correct responses and implemented a correction procedure contingent on incorrect responses. In the praise-only-for-correct-responses (PC) condition, researchers delivered contingent praise…

This article presents a novel approach to introducing principal component analysis (PCA), using summary tables and descriptive statistics. Given its applicability across a variety of academic disciplines, this topic offers abundant opportunity for class discussion and activities. However, teaching PCA in an introductory class can be challenging…

In this paper, a problem set activity focused on understanding and applying unsupervised and supervised chemometric methods for the analysis of biodiesel-diesel blended fuels is described. This problem set was utilized in two upper-level analytical elective courses aimed for junior and senior level students. The data set consists of peak areas…

In this study, an instrument was developed to measure an instructor's value and incorporation of intersectionality theory in the classroom. Through a Delphi study, a list of items was devised, and then a pilot study was conducted to collect responses from 161 participants. The result is the development of the Intersectionality Pedagogy Scale, a…

The importance of understanding student attitudes has become paramount in the successful deployment of blended learning. This study aimed to examine the factorial structure of a scale designed to assess university students' attitudes towards blended learning. Using a descriptive quantitative research approach, the study included a sample of 889…

Montessori education has existed for more than 100 years and counts almost 16,000 schools worldwide (Debs et al., 2022). Still, little is known about the implementation and fidelity of Montessori principles. Measuring implementations holds significant importance as it provides insight into current Montessori practices and because it is assumed…

In recent years, studies by education researchers indicate that, despite various instructional methods to enhance the conceptual understanding of seasons, the reasons for the formation of seasons and the processes involved are still not fully grasped. This research aims to investigate the fundamental reasons for the difficulties in comprehending…

The Teacher Efficacy for Inclusive Practices (TEIP) scale is a widely used instrument for assessing teachers' effectiveness in implementing inclusive practices. The TEIP has not been validated in Bosnia and Herzegovina (BIH). The goal of the present study was to conduct a confirmatory factor analysis (CFA) of the TEIP in a sample of teachers in…

The present study aims to develop a valid and reliable pedagogical literacy scale based on teachers' views. It also aims to investigate the variations in pedagogical literacy levels of teachers based on gender, educational level, and professional seniority variables to test the functionality of the pedagogical literacy scale. The study was…

I present a new model of the self-regulation of virtue that integrates perspectives on emotion, cognition, and motivation. Across three vignette-based studies in US/UK (N = 1,540), I developed through exploratory and confirmatory factor analysis a multi-item measure of broadening and defensive responses, the Self-Regulation of Virtue Inventory…

Promoting positive development may lead to young people's active contributions to their environment through positive attitudes and behaviours. The Climate Change Attitude Survey (15-item version) aims to identify climate change attitudes differences in groups of students and to assess pre- to post-intervention attitude changes. We intended to…

Educational researchers have offered a number of different measures to explore the use of equity pedagogies. Such measures traditionally use teacher self-report as the primary metric and few investigate from the student perspective. This exploratory psychometric article details the use of a new instrument, the Asset-Based Equity Pedagogy Scale…

This mixed methods study examined how a National Professional Development Grant project's first cohort (2018-2020) in the Midwest impacted mostly White and monolingual inservice teachers who work with emergent bilingual learners (EBLs). Two research questions (RQs) guided this study: RQ1: What were the inservice teachers English language…

The purpose of this paper is to conduct a cross-cultural assessment of the Community of Inquiry (CoI) instrument [Arbaugh, J. B., Cleveland-Innes, M., Diaz, S. R., Garrison, D. R., Ice, P., Richardson, J. C., & Swan, K. P. (2008). Developing a community of inquiry instrument: Testing a measure of the community of inquiry framework using a…
