This study examines foster child case records to understand how intelligence testing was used by guidance counsellors and social workers to negotiate welfare resources with poor youths in the early twentieth century. Psychological testing justified racial hierarchy in a scientific language suited for a rational professional bureaucracy. Yet, it…

Nonparametric or kernel regression estimation of item response curves (IRCs) is often used in item analysis in testing programs. These estimates are biased when the observed scores are used as the regressor because the observed scores are contaminated by measurement error. Accuracy of this estimation is a concern theoretically and operationally.…

Null hypothesis testing (NHT) is the most commonly used tool in empirical psychological research even though it has several known limitations. It is argued that since the hypotheses evaluated with NHT do not reflect the research-question or theory of the researchers, conclusions from NHT must be formulated with great modesty, that is, they cannot…

The genome projects of the past decades have created extensive databases of biological information with applications in both research and education. We describe an inquiry-based exercise that uses one such database, the National Center for Biotechnology Information Influenza Virus Resource, to advance learning about influenza. This database…

While there is ample evidence that children treat words as mutually exclusive, the cognitive basis of this bias is widely debated. We focus on the distinction between pragmatic and lexical constraints accounts. High-functioning children with autism spectrum disorders (ASD) offer a unique perspective on this debate, as they acquire substantial…

Autistic Spectrum Disorder (ASD) and Specific Language Impairment (SLI) are disorders of communication that are sometimes thought to show similar structural language difficulties. Recent research has even suggested that they might be aetiologically related. However, it may be that standardized language tasks are not sensitive enough to detect…

This study examined the within-subject stability of 150 participants who performed both a sorting task and a property-generation task over multiple sessions, focusing on three concrete concept categories (food, animals and bathroom products). We hypothesized that (1) the within-subject stability would be higher in the sorting task than in the…

The purpose of this study was to investigate the effects of blocked and random practice schedules on the performance accuracy, speed, temporal evenness, and attitude of beginning band students in a group instructional setting. The research assumptions were based on the contextual interference hypothesis, which predicts that a blocked practice…

This article reports the results of an experimental study on the effectiveness of mobile technology (WhatsApp) in improving the critique writing skills of English as a Foreign Language learners and increasing their motivation for learning. The participants (n = 52) are Average-English proficient learners enrolled in two writing courses given at…

The aims of this study were to investigate the effects of discrepancies between teachers' perceptions of students' motivation and students' reports of their motivation on math and English grades and to identify possible gender and ethnic differences. Participants included 215 low-income, ethnic-minority students and their teachers in academically…

This study gathered, analyzed, and compared perspectives of students who were honors-eligible but never began the program, students who began in honors and discontinued their enrollment, and those who were persisting in honors. Broadly speaking (and not surprisingly), the responses of students persisting in honors reflected the most positive…

The objective of this study is to analyze the relationship between preservice teachers' time and study environment management, effort regulation, self-efficacy beliefs, control of learning beliefs and metacognitive self-regulation. This study also investigates the direct and indirect effects of metacognitive self-regulation on time and study…

The Teaching Resources Center (TRC) was developed at the university as an integrated project funded by the Ministry of Education. The focus of the TRC is not only on enhancing students' motivation in self-access study and written English, but also on providing the resources for research and information to develop lifelong learners and independent…

Canada welcomes around 24,000 refugees annually (Citizenship and Immigration Canada 2015; 2016). Many adult learners with refugee experiences join English as an Additional Language (EAL) classes every year, whether these classes be federally or provincially funded. These adult learners with refugee experiences bring to EAL classes varied…

Using a large, longitudinal data set that represents 701 state-funded pre-k classrooms and over 2,900 children enrolled in 11 states, the current study examined two hypotheses: (1) children would be perceived to be better adjusted at the beginning of pre-k when rated by a same-race teacher than by a different-race teacher, and (2) children would…
