The student evaluation of teaching process is generally thought to produce reliable results. The consistency is found within class and instructor averages, while a considerable amount of inconsistency exists with individual student responses. This paper reviews these issues along with a detailed examination of common measures of reliability that…

This note extends the results in the 2016 article by Raykov, Marcoulides, and Li to the case of correlated errors in a set of observed measures subjected to principal component analysis. It is shown that when at least two measures are fallible, the probability is zero for any principal component--and in particular for the first principal…

The present studies examine whether and how 18-month-olds use informants' accuracy to acquire novel labels for novel objects and generalize them to a new context. In Experiment 1, two speakers made statements about the labels of familiar objects. One used accurate labels and the other used inaccurate labels. One of these speakers then introduced…

Students are often encouraged to learn 'deeply' by abstracting generalizable principles from course content rather than memorizing details. So widespread is this perspective that Likert-style inventories are now routinely administered to students to quantify how much a given course or curriculum evokes deep learning. The predictive validity of…

Psychological inflexibility has been associated with several mental health indicators. The Avoidance and Fusion Questionnaire for Youth (AFQ-Y) has been the most used measure to assess psychological inflexibility in adolescents, having been adapted to several different languages, including Portuguese. However, the short 8-item version of this…

Language learner attitudes about technology have traditionally been studied using survey data, but those surveys have primarily been based on disparate constructs and conceptualizations of learner attitudes. The lack of a common measure, or one that reflects other levels and contexts of learning, has limited the investigation about language…

The importance of the opportunity to learn (OTL) for mathematics achievement has been extensively researched. However, there were still unanswered questions regarding OTL's measurement, analytical level, and relationship with motivational beliefs. To fill in the gaps, we aimed to (1) scrutinize the reliability and validity of OTL, (2) investigate…

Background: The Teacher-Student relationship (TSR) is instrumental for young children and adolescents' socio-emotional development and wellbeing as well as academic engagement and progress. Aims: The primary aim of this study was to test the psychometric properties, including reliability and factorial, convergent, and predictive validity, of the…

In Saskatchewan, school divisions have been largely tasked with creating classroom-based assessment policy as, until very recently, the province lacked a current, Ministry-produced guiding document. Using an inductive and qualitative approach to summative content analysis, informed by a policy analysis framework, this project focused on school…

This study aims to examine the effect of diagnostic labels on the responses of preservice early childhood teachers to the inclusion of children with special needs in general education classes. 228 preservice early childhood teachers, who participated in the study, answered the Demographic Information Form and the Teachers' Comfort and Concern…

This paper aims to describe the development process of the Observation Protocol for Teaching Activities in Mathematics (POAEM) and to report the findings from the qualitative and statistical analyses used to provide evidence of validity and reliability of the information collected with the first version of the POAEM. As part of this development…

This study was conducted to develop a valid and reliable measurement tool that can identify middle school students' self-regulation skills. Firstly, the literature was utilized in the development of the measurement tool. The form was finalized with the support of the opinions of different experts and a trial application. Then, the form was…

This investigation utilized publicly available data from the High School Longitudinal Study 2009 (HSLS:09) by the National Center for Educational Statistics (NCES) to examine any latent structures among variables which may empirically support the validity and reliability of a mathematical sense of belonging (MSB) construct. Using the nationally…

Teachers at St. Scholastica School, a pseudonym, an all-girls Catholic high school, varied in approaches to discipline creating an unequal distribution of student citations and negatively impacting student experience. An Improvement Science approach identified two potential drivers of change: inconsistency in disciplinary policy and variation in…

Intoxicated witnesses are common, making it important to understand alcohol's impact on witness accuracy and suggestibility. Participants assigned to an immediate retrieval condition encoded and recalled in one of the three intoxication conditions: sober control, placebo, or intoxicated. Participants in the delayed retrieval condition were…
