The modeling of rates of biochemical reactions--fluxes--in metabolic networks is widely used for both basic biological research and biotechnological applications. A number of different modeling methods have been developed to estimate and predict fluxes, including kinetic and constraint-based (Metabolic Flux Analysis and flux balance analysis)…

OpenCourseWare (OCW) and Massive Open Online Courses (MOOCs) have gained increasing popularity and importance because they greatly expand students' access to university lectures. Although the main component of OCW and MOOC platforms is lectures, their differences may potentially affect the difficulty of academic listening comprehension. This study…

This is potentially the first study that addressed the Puerto Rican high school students' chemistry knowledge acquisition using traditional teaching and Physics Education Technology. The problem addressed by this quantitative comparative quasi-experimental study was that students' showed a disadvantage on chemistry knowledge acquisition over other…

The way in which information is presented can influence students' judgments of learning (JOLs). Carpenter, Wilford, Kornell, and Mullaney (2013) found that students reported higher JOLs after viewing a fluent lecturer (good speaker) versus a disfluent lecturer, whereas actual learning performance was unaffected by lecturer fluency. The current…

Many online videos feature an instructor on the screen to improve learners' engagement; however, the influence of this design on learners' cognitive load is underexplored. This study investigates the effects of instructor presence on learners' processing of information using both subjective and psychophysiological measures of cognitive load. Sixty…

Definitions are fundamental to any mathematics classroom. We consider how definitions are presented in textbooks and instructors' lecture notes, and whether students are positioned to gain a full understanding of new terms. Four textbooks, covering precalculus, calculus, and analysis, as well as three professors' Calculus I lecture notes are…

The COVID-19 pandemic has fundamentally affected all the spheres of human life, including education. Universities worldwide have established distance learning, which demanded combining and improving both traditional and innovative education forms. The article offers a comprehensive analysis of pre-recorded mini-lectures in the educational space of…

Many factors predict academic performance at university but accessing lecture recordings has not been established as one. Our aims were to quantify how and why biochemistry students accessed lecture recordings and to determine any association between accessing lecture recordings and academic outcomes. Lecture recording access data was collected…

This study investigated the belief that student attention declines after the first 10 to 15 min of class by analyzing vigilance decrement in a guided inquiry physical science course. We used Tobii Glasses, a portable eye tracker, to record student gaze during class sessions. Undergraduate students (n = 17) representative of course demographics (14…

Social justice is an American Psychological Association (APA) ethical principal which is often taught in content courses (e.g. social psychology, developmental psychology, introductory psychology) but rarely covered in psychological statistics courses. This is problematic, as psychology students may assume that bias is not an issue when…

Digital technologies have gained much popularity in education thanks to the cost efficiency they gain through scalability. While the acceptance of some of these new digital technologies has been investigated, there are few direct comparisons. The most established model for measuring acceptance is the technology acceptance model, which can predict…

Scholarly opinion on the usefulness of podcasting in higher education has been mixed. Considering the variety of methods of teaching and learning, the existing scholarship on the subject in any particular one has been inadequate to measure podcasting's promise. This case study of a podcast-infused, fully-online Western Civilization survey course…

Lecture Capture (LC) material is accepted to be an available and accessible resource for students in universities across the world. This exploratory study investigates the "when viewing" LC material engagement of accounting undergraduate students. Three categories of engagement are defined, Near-Event-Viewing (NEV), Get-Round-to-Viewing…

Second language (L2) learning has largely occurred in the traditional lecture-based classroom setting. Studies show that the lecture format has an impact on student outcomes and perceptions of classroom learning. Negative impacts include insufficient time for reinforcement activities, reviewing lecture materials, and engaging in conversation…

We created a 2-week, dual-module summer course introducing high school students to environmental toxicology by teaching them quantitative polymerase chain reaction (qPCR) as a way to quantify gene expression of chemical defense proteins in response to exposure to environmental pollutants. During the course, students are guided through the various…
