This article contributes to the research literature concerning prospective elementary teachers' mathematical thinking and learning with a focus on flexibility. We present a case study of a prospective elementary teachers' development of flexibility in mental addition and subtraction during a Number and Operations course. Building upon the…

Introduction: Nowadays, providing the access to learning appears as an emphasized priority for every stage of life, due to the demographic changes, even near the place of residence or with the utilization of the possibilities of the new informational and communicational technologies, which bring new possibilities also in the dimension of learning…

During their time as Teaching Assistants (TAs), graduate students develop a variety of skills, knowledge, and attitudes (SKAs) based on teaching and related facilitation experiences. As TAs move on to future opportunities, their prior experiences form a foundation upon which additional teaching experience builds. Presently, there are few tools to…

Instructional technologists and faculty in post-secondary institutions have increasingly adopted learning analytics interventions such as dashboards that provide real-time feedback to students to support student' ability to regulate their learning. But analyses of the effectiveness of such interventions can be confounded by measures of students'…

We assessed 24-month-old infants' lexical processing efficiency for both novel and familiar words. Prior work documented that 19-month-olds successfully identify referents of familiar words (e.g., The dog is so little) as well as novel words whose meanings were informed only by the surrounding sentence (e.g., The vep is crying), but that the speed…

Over the course of history, the structures of societies have changed at certain periods depending on technological and scientific developments. In today's societies, such mental processes as information processing and production have become prominent and the educational systems are revised according to the constructivist approach, which focuses on…

Bayesian Knowledge Tracing (BKT) is a commonly used approach for student modeling, and Long Short Term Memory (LSTM) is a versatile model that can be applied to a wide range of tasks, such as language translation. In this work, we directly compared three models: BKT, its variant Intervention-BKT (IBKT), and LSTM, on two types of student modeling…

This dissertation examines the thesis that implicit learning plays a role in learning about scientific phenomena, and subsequently, in conceptual change. Decades of research in learning science demonstrate that a primary challenge of science education is overcoming prior, naive knowledge of natural phenomena in order to gain scientific…

The purpose of this hermeneutic phenomenological study was to describe how students experience success in mathematics remediation at a four-year private institution in the central United States. Success in a remedial mathematics course was defined as one's completion of a required remedial mathematics course having earned an overall grade of 90%…

Teacher education programs in 40 states require teacher candidates working toward visual art certification to take edTPA, a high-stakes summative performance assessment developed by Stanford Center for Assessment, Learning and Equity (SCALE) and distributed by Pearson's Evaluations Systems (Pearson Education, 2018). Since its implementation in…

This paper studies how the effectiveness of teachers varies by classroom composition. We combine random assignment of teachers to classrooms with rich measures of teacher effectiveness based on a popular observational protocol, Framework for Teaching, to overcome key endogeneity concerns related to measurement and matching. We find that…

The state of education in the United States faces many challenges in preparing students for the workforce and postsecondary education. These challenges are heightened at the postsecondary level for schools of nursing. The current shortage of nurses will continue to rise if recruitment and retention strategies are not employed. The purpose of this…

Previous research on multiple external representations (MER) indicates that sequencing representations (compared with presenting them as a whole) can, in some cases, increase conceptual understanding if there is interference between internal and external representations. We tested this mechanism by sequencing different combinations of scientific…

Executive functions enable flexible thinking, something young children are notoriously bad at. For instance, in the dimensional change card sort (DCCS) task, 3-year-olds can sort cards by one dimension (shape), but continue to sort by this dimension when asked to switch (to color). This study tests a prediction of a dynamic neural field model that…

How does the visual system recognize images of a novel object after a single observation despite possible variations in the viewpoint of that object relative to the observer? One possibility is comparing the image with a prototype for invariance over a relevant transformation set (e.g., translations and dilations). However, invariance over…
