Background: Undergraduate STEM instructors want to help students learn and retain knowledge for their future courses and careers. One promising evidence-based technique that is thought to increase long-term memory is spaced retrieval practice, or repeated testing over time. The beneficial effect of spacing has repeatedly been demonstrated in the…

The uniformly most accurate (UMA) is an important optimal approach in interval estimation, but the current literature often introduces it in a confusing way, rendering the learning, teaching and researching of UMA problematic. Two major aspects cause this confusion. First, UMA is often interpreted to maximize the accuracy of coverage, but in fact,…

The present study evaluated the use of computerized equivalence-based instruction (EBI) to teach classes representing schedules of reinforcement to staff members. Four, 5-member classes representing fixed ratio, fixed interval, variable ratio, and variable interval schedules of reinforcement were taught. The participants were 16 staff members…

When playing card games, how many times should a deck be shuffled in order to achieve randomness? This article shows how card shuffling can be used as a classroom exercise to reinforce construction and interpretation of confidence intervals.

This study assessed the efficacy of the spaced learning method compared to the activity-oriented method in improving chemistry achievement among high school students, focusing on different cognitive domains. An experimental design involving pre and post-test control groups was employed, with 106 students from two schools participating. The…

System pausing at pre-determined positions during multimedia presentations can enhance multimedia learning. However, the pause positions are usually set up based on the structure of the learning material (e.g., segmentation principle) rather than on the complexity of its different sections (as determined by levels of element interactivity,…

Spaced and interleaved practices have been identified as effective learning strategies which sometimes are conflated as a single strategy and at other times treated as distinct. Learning sessions in which studying information or practicing problems are spaced in time with rest-from-deliberate-learning periods between sessions generally result in…

James Banks's framework for determining the levels of integration of multicultural content in teachers' pedagogy has long been a tool used by researchers worldwide. This article introduces the Holistic Analysis of Multicultural Teaching Framework that rethinks Banks's framework to allow research analysis to capture the hybrid and fluid aspects of…

We conducted a review of the literature on articles published between 1987 and 2017 on the application of constant time delay (CTD) as an instructional procedure to teach students with mild or moderate intellectual disability. An analysis of 18 empirical studies supported the effectiveness of the CTD procedure. Measures included acquisition,…

Preservice undergraduates should acquire many skills in their teacher preparation program that support them as future effective teachers. For special education preservice teachers, one of these important skills is teaching with the constant time delay procedure, an evidence-based practice for teaching learners with moderate or severe disabilities.…

It is well established that gesture facilitates learning, but understanding the best way to harness gesture and "how" gesture helps learners are still open questions. Here, we consider one of the properties that may make gesture a powerful teaching tool: its temporal alignment with spoken language. Previous work shows that the…

Teachers have used the method of repeated readings to build oral reading fluency in students with and without special needs. A new fluency building intervention called interval sprinting uses shorter timing intervals (i.e., sprints) across a passage. This study used an alternating treatment design to compare repeated readings and interval…

There has been extensive research using centrality measures in educational settings. One of the most common lines of such research has tested network centrality measures as indicators of success. The increasing interest in centrality measures has been kindled by the proliferation of learning analytics. Previous works have been dominated by…

A lab activity for teaching physics students the fundamentals of statistical analysis during the first few weeks of instruction is described. This activity involves students timing a pulse of light generated by an Arduino device of fixed duration with individual timers (e.g. stopwatch, iPhone timer). To select the most precise timing methods and…

Extension professionals are increasingly using geographic information system (GIS) technology to develop and inform programs and services. In this article, we use a mapping exercise to demonstrate how the unit of data can be applied and inadvertently misrepresented in GIS mapping. We contrast the use of counts, percentages, and location quotients…
