The notion of "Micro-Learning" (ML) has been repeatedly accented as a successful learning approach in different learning phenomena. Despite these optimistic emphases, several studies lack a theoretical grounding in adoption of ML, thus missing a shared perspective of the education community. The scarce theoretical justification for…

Previous work with complex memory span tasks, in which simple choice decisions are imposed between presentations of to-be-remembered items, shows that these secondary tasks reduce memory span. It is less clear how reconfiguring and maintaining various amounts of information affects decision speeds. We introduced preliminary "lead-in"…

To date, of the many studies on early algebraic thinking, none, to our knowledge, has examined the relationships between algebraic thinking and negative numbers. Students encounter persistent difficulties in dealing with these numbers, and we believe that these could be addressed through the development of algebraic thinking. We are particularly…

The ACTFL Oral Proficiency Interview--computer (OPIc) employs a self-assessment instrument to determine the nature of the speaking prompts to which the test taker will respond and, thus the difficulty of the test. Grounded in research demonstrating varying levels of accuracy in self-assessment among language learners, this study examines the…

The objective of this research has been the analysis of the effectiveness of sports performance through a program, based on the assimilation of contents from a previous diagnosis. The almost-experimental design was applied like a pre- during program. Eighty-two students from Basic Education Career of UPSE have participated in this study, developed…

Novice programmers, who have yet to form effective mental models of the domain, often experience high cognitive load, low confidence, and high anxiety, negatively affecting learning and retention rates. These cognitive and affective limitations pose an instructional challenge. This study aimed to investigate the effectiveness of a whole-task…

Three studies examine a novel pathway by which the perseverance component of the personality trait "grit" might predict college students' behavioral persistence when solving challenging math problems. Specifically, we focus on the intervening role of what we refer to as "math-specific self-perceptions of perseverance," which…

Based on our work teaching undergraduate Calculus courses, we offer insight into teaching the chain rule to reduce cognitive load for students. A particularly difficult topic for students to grasp, problems likely arise due to student struggles with the concept of function and, particularly, function composition relative to when they first…

The first part of this dissertation conducts a large-scale study comparing general and usage-based indices of syntactic complexity in L2 Mandarin writing samples across a wide range of proficiency levels. To do this, the Tool for the Automated Analysis of Syntactic Sophistication and Complexity (TAASSC; Kyle, 2016) was adapted for Mandarin by…

This study compares the impact of two New York State mathematics Regents-level course sequences on the number of secondary mathematics courses taken by New York City Department of Education (NYCDOE) students and explores the potential that programming decisions could increase or diminish the mathematics learning opportunity and achievement of…

Of the three main subdivisions in chemistry, physical chemistry often presents a challenge when delivered to those not majoring in chemistry or its cognate disciplines. This is, at least in part, due to the seemingly unrelatedness of the subject to students' anticipated career. We describe the redesign of a nested physical chemistry course for…

Inquiry is one integral part of science learning. Understanding the underlining meaning and the complete procedures of inquiry-based laboratories would be beneficial to student teachers' future work. Therefore, it is necessary for student teachers to perform inquiry-based laboratories and know how to demonstrate them to school students. However,…

Army senior leaders believe in preparing for future conflicts; the Army must shape future leaders' knowledge, skills, and attributes through rigor and critical thinking in professional military education. The problem addressed by this study was understanding Army senior leaders' perceptions concerning the appropriateness of rigor and critical…

This case study describes in detail the process of cocreating a self-reflection tool for inclusive classrooms in the context of a university-based innovation lab in Estonia named Proovikivi (https://proovikivi.ee/). The study, which follows an exploratory, interventional, and qualitative case study methodology, was implemented in three phases…

Running span can be performed by either passively listening to memory items or actively updating the target set. Previous research suggests that the active updating process is demanding and time consuming and is favored at slow rates of presentation while the passive strategy is employed at fast rates. Two experiments examined the time course of…
