Colleges across the country struggle with determining the most appropriate means of placing students into math and English coursework. Most colleges utilize a single high-stakes standardized placement exam to assess incoming students and use strict cut-scores to determine students' placement. However, the ability of these tests to accurately place…

Early childhood educators' (ECEs) self-efficacy is often predictive of their ability and likelihood of promoting healthy activity behaviors in childcare settings. To date, ECEs' physical activity and sedentary behavior-related self-efficacy has been measured in a variety of ways in childcare-based research, creating difficulty when comparing…

In today's society, creativity plays a key role, emphasizing the importance of its development in K-12 education. Computing education may be an alternative for students to extend their creativity by solving problems and creating computational artifacts. Yet, there is little systematic evidence available to support this claim, also due to the lack…

Using a multiphased and mixed method approach to instrument development, the ISS-C was composed of 16 items extracted into four factors, which demonstrated adequate model fit. The ISS-C scores showed good internal consistency, convergent validity, and temporal stability, while some aspects of discriminant validity remain suboptimal.

There is a need to investigate student intention to participate in online discussion forums in the context of online collaborative learning due to the importance of student participation and the widespread student inactivity reported in some studies. Student participation in online discussion forums could be predicted by the constructs included in…

Mixture IRT models address the heterogeneity in a population by extracting latent classes and allowing item parameters to vary between latent classes. Once the latent classes are extracted, they need to be further examined to be characterized. Some approaches have been adopted in the literature for this purpose. These approaches examine either the…

Multiple choice tests are widely applied to assess students' knowledge in science education. This study aimed at assessing the validity and reliability of Science Multiple-choice Test in Malaysia. The items for this test were formulated by the researcher together with a panel of science teachers and the head of the science department with close…

Purpose: The Vocal Tract Discomfort Scale (VTD Scale) is a self-rating questionnaire investigating physical symptoms in the larynx associated with vocal pathology. The aim of this work was to investigate the reliability, validity, sensitivity, and specificity of the first German version and to provide normative data with thresholds for pathology…

A subtest of the LLAMA test battery (LLAMA_D) has been proposed as a potential test of implicit learning aptitude. To improve its construct validity, in the present study, the original LLAMA_D (a) instructions for incidental learning were modified, and (b) confidence ratings of test responses and (c) reaction time (RT) measurements were added.…

The purpose of this study was to adapt the Self Description Questionnaire for Preschoolers into Turkish and to examine the self-concept of Turkish preschoolers based on sex and age. A total of 420 preschoolers participated in the study. The viability of the six-factor solution for the Turkish sample was examined using the first- and second-order…

The aim of the first stage of the research was to examine the opinions of prospective mathematics teachers about what features a question prepared to develop and measure ML should have to be effective and qualified. Moreover, it was aimed to determine the degree to which prospective teachers apply these qualifications in questions they design to…

In undergraduate mathematics, deductive reasoning plays important roles in teaching and learning various ideas, and is primarily characterized by the concept of logical implication. This comes up whenever conditional statements are applied, i.e., one checks if a statement's hypotheses are satisfied and then makes inferences. In calculus, students…

The Modified Checklist for Autism in Toddlers, Revised, with Follow-Up (M-CHAT-R/F) is the most widely used screener for ASD. Despite the comparable rate of ASD in Black and White children, the M-CHAT-R/F was validated on a primarily White, Non-Hispanic sample. Few studies have assessed whether the screener performs adequately with racial…

School climates are known to be associated with a range of student outcomes (including academic, social, behavioural and affective), and much work to date has focused on gathering students' perceptions of their school climate to inform ongoing improvement efforts. However, parents and caregivers, as well as students, are also influenced by the…

This commentary discusses the issue of small samples in instructed second language acquisition research. We discuss the current state of affairs, and consider the disadvantages of small samples. We also explore other considerations regarding sample size, such as research ethics and ecological validity. We present a range of recommendations for…
