This study investigated the development of rapid visual object categorization. N = 20 adults (Experiment 1), N = 21 five to six-year-old children (Experiment 2), and N = 140 four-, seven-, and eleven-month-old infants (Experiment 3; all predominantly White, 81 females, data collected in 2013-2020) participated in a fast periodic visual stimulation…

This paper studies the knowledge developed by a group of sixty-two pre-service primary teachers during a training session on the definition of a polygon and the mathematical practice of defining. We explore the knowledge developed by pre-service teachers when they carry out a series of training tasks oriented around the practice of defining with…

Research examining the joint relationships between test anxiety, metacognition, and mathematics achievement revealing the mediational role of metacognition in the relationship between test anxiety and mathematics achievement is sparse. A mediation study was designed to redress this imbalance. The Children's Test Anxiety Scale (CTAS), Junior…

It has been reported for decades that preschool children (age 4-7) tend to assign non-adult-like interpretations for sentences with pre-subject exclusive only. This study reports findings from two experiments investigating (1) the effects of (in)congruent implicit questions in discourse contexts and (2) word order transformation on children's…

Previous research has shown that task repetition can positively affect L2 oral performance. However, few studies have explored the effects of task repetition on young EFL learners' production. Also, task repetition research has paid little attention to effects of "spacing" examined through longer time intervals between the two occasions…

Inquiry includes a broad spectrum of approaches, depending on students' responsibility over the process and the extent of the teacher's guidance. While numerous studies have examined students' achievements and engagement across different types of inquiry-based environments, analyses of teachers' guidance during the process are lacking. Therefore,…

Introduction: Achievements of students in higher education are influenced by several factors. From the students' perspective a key factor is the motivation, without which it is extremely difficult to make any progress, and from the teachers' perspective the conservative methodological culture is primarily responsible for the fact that students are…

Deliberation and inquiry can go hand-in-hand. Inquiry-based learning calls on teachers to facilitate student-led discovery, something that can only happen when students ask questions and weigh possible answers before settling on a plausible and evidentiary answer. Teaching through inquiry is about setting students up to wrestle with the issue at…

Cross-situational word learning, the ability to decipher word-referent links over multiple ambiguous learning events, has been documented across development and proposed to be key to vocabulary acquisition. However, this work has largely focused on learning from one-to-one structure, where each referent is consistently linked with a single label.…

Taking the visual perspective of another individual is an important skill in social communication, and is termed visual perspective-taking (VPT). Individuals with autism spectrum disorder who have deficits in social interaction show relatively lower performance on VPT tasks than individuals who achieve age-appropriate developmental milestones.…

In this dissertation I explore instructors' work with instructional tasks as they plan to introduce various representations of derivatives. Drawing on the notion of "framing" from sociology, I adopt a situative lens to study calculus instructors' planning of instructional tasks. I rely on Herbst and Chazan's (2012) notion of…

The current study examines the digital behaviors of 124 university students enrolled in a blended learning class in Korea. The students were divided into two groups (upper and lower) based on their scores on a self-regulated learning questionnaire. Their digital behaviors were compared across four areas: (a) task completion scores; (b) strategy…

Theory of Mind (ToM), a central feature of social cognition, impacts social functioning and academic competencies. Yet, the interplay of ToM and self-concept in academic context remains unknown. This study examines how ToM shapes adolescents' academic self-concept and its association with academic competence, while considering the role of gender…

The gender gap in STEM careers is shaped in part by educational choices. This study investigates two interventions--absolute performance feedback and personalized advice--aiming at narrowing the gender disparities in investments in math skills. Using an online lab experiment, participants chose between a math or verbal task after receiving one of…

Unlike with the typically developing population, non-typically developing individuals, especially those with intellectual disabilities, have usually been recommended to learn and use only one language, despite perhaps coming from bilingual families or living in multilingual environments. This common practice, however, is not backed by empirical…
