Numerous studies have shown that learned information practiced by testing is better retained than that practiced by restudying (the testing effect). However, results are inconsistent regarding the effect of working memory (WM) capacity on the testing effect. Here, we hypothesize that the effect of WM only emerges when task demands challenge WM…

Notwithstanding the growing advantages of incorporating Augmented Reality (AR) in science education, the pedagogical use of AR combined with Pedagogical Agents (PAs) remains underexplored. Additionally, few studies have examined the integration of Generative Artificial Intelligence (GAI) into science education to create GAI-enhanced PAs (GPAs)…

Students' lack of interest in chemistry becomes a significant issue in chemistry learning. This may be caused by the negative perception of students about their difficulties in learning chemistry. This study aims to explore views and causes of difficulties in learning chemistry from the perspective of secondary school students. This research was…

Responding to calls for more future-oriented teaching and learning, an increasing number of institutions of higher education have recently implemented challenge-based learning (CBL). Through work on open-ended and real-life challenges, CBL aims to stimulate students to take the lead in their own learning, acquire and apply knowledge relevant for…

In this study, the American pianist and composer Jeff Manookian's "Etudes for the Intermediate Pianist" method was examined. In this qualitative study, the descriptive research model was employed and the literature was scanned through document review. As a result of the examination, no study was found on Manookian's piano etudes. To that…

The possible dependency of criterion validity on item formulation in a multicomponent measuring instrument is examined. The discussion is concerned with evaluation of the differences in criterion validity between two or more groups (populations/subpopulations) that have been administered instruments with items having differently formulated item…

Previous work has shown that challenging learning strategies like "desirable difficulties" improve long-term learning. Nonetheless, because they might be regarded as strict and demanding learning strategies, they should not be perceived as positive by everyone. They should, however, fit conservative political attitudes since those are,…

Background and Context: Block-based programming is a popular approach to teaching introductory programming. Block-based programming often works in the context of microworlds, where students solve specific puzzles. It is used, for example, within the Hour of Code event, which targets millions of students. Objective: To identify design guidelines…

As humans, we use language with ease and speed, solving the complex computational problem of processing form and meaning seemingly without effort. This dissertation studies how the properties of language enable us to achieve this, by investigating what is computationally difficult about language, and what is easy. We first investigate the…

Do lifeguards monitor events according to the level of danger they pose to the patron? This study examined this question by displaying 40 min of video of natural swimming activity to three lifeguards while an eye-tracker recorded their eye position. In a separate session, those same lifeguards viewed 100 short video clips of some of the incidents…

Based on hundreds of thousands of hours of data about how students learn in massive open online courses, educational machine learning promises to help students who are learning to code. However, in most classrooms, students and assignments do not have enough historical data for feeding these data hungry algorithms. Previous work on predicting…

The law of Non-Original Malappropriate Eponymous Nomenclature (NOMEN) states that no phenomenon is named after its discoverer. However, eponymous terms are rife in the anatomical and medical literature. In this viewpoint commentary, the authors discuss the history of anatomical eponyms, explain the additional cognitive load imposed by eponyms that…

We revisit the empirically observed positive correlation between DIF and difficulty studied by Freedle and commonly seen in tests of verbal proficiency when comparing populations of different mean latent proficiency levels. It is shown that a positive correlation between DIF and difficulty estimates is actually an expected result (absent any true…

Purpose: The purpose of this study was to determine the effect of cognitive load on relative fundamental frequency (RFF) in individuals with healthy voices. Method: Twenty adults with healthy voices read sentences under different cognitive load conditions. Each sentence contained color terms printed in colored ink, creating an embedded Stroop…

Purpose: Prior work suggests that voice onset time (VOT) may be impacted by laryngeal tension: VOT means decrease when individuals with typical voices increase their fundamental frequency (f[subscript o]) and VOT variability is increased in individuals with vocal hyperfunction, a voice disorder characterized by increased laryngeal tension. This…
