Although there has been extensive research on students' understanding of the particulate nature of matter (PNM), there is still a lack of research on contexts that can be used to teach this challenging topic. In a previous design-based research study, the authors developed a teaching-learning sequence (TLS) on the PNM in the context of crystal…

This study aimed to reveal the attitudes of the students who were subjected to measurement and evaluation in an online testing environment towards the computer based testing (CBT) platform and the factors that affect their attitudes. It also examined the students' cognitive loads in the exam designed with multimedia elements from message design…

We explore the effect of students' perceived task difficulty on the mathematics self-efficacy -- performance relationship. Specifically, we expand on previous reciprocal effects studies through including students' self-efficacy for different levels of task difficulty in an empirical investigation. We examined students' self-efficacy for easy,…

The purpose of this study was to examine the use and cognitive load associated with Open Educational Resources (OERS) and Affordable Digital Textbook (ADT) among prelicensure Baccalaureate of Nursing students in an asynchronous on-line health policy course. OERS and ADT provide low student cost curriculum options for nursing faculty. The…

Knowledge of embryology is foundational for understanding normal anatomy and birth defects, yet, embryology is a notoriously difficult subject for medical students. Embryonic lateral folding in particular is one of the most challenging concepts in embryology. Highly effective teaching methods that promote active engagement with dynamic,…

When examinees perceive a test as low stakes, it is logical to assume that some of them will not put out their maximum effort. This condition makes the validity of the test results more complicated. Although many studies have investigated motivational fluctuation across tests during a testing session, only a small number of studies have…

We developed a Quantum Mechanics Conceptual Understanding Survey (QMCUS) in this study. The survey was conducted using a quantitative methodology. A multiple-choice survey of 35 questions was administered to 338 undergraduate students. Three experienced quantum mechanics instructors examined the validity of the survey. The reliability of our…

This paper reports the findings of a study that investigated why a large number of test-takers show a low performance in four language skills (listening, speaking, reading, and writing) offered in an entry test used by a College of Technology in Oman to place students in advanced diploma and bachelor's degree programs. The main research question…

Recent research based on the Dweck's mindset theory has shown that persons with a growth mindset who believe traits such as intelligence are malleable may put forth more effort and have greater academic success than those with a fixed mindset. However, little research has been conducted on mindsets of college students, many of whom enter…

In the current study we examined students' course performance, perceptions, and self-reported use of an open textbook compared to a traditional publisher's textbook in an introductory psychology course. Sixty students from two course sections used either an open textbook or a traditional textbook. To minimize the effect of confounding variables,…

Linear pattern is the primary material in learning number patterns in junior high schools, but there are still many students who fail to generalize the linear pattern. The students' failure in generalizing the pattern occurred when the students ended to view the problems globally without breaking them into the constructors' components such as the…

Artificial intelligence (AI) technologies have the potential to reduce the workload for the second language (L2) teachers and test developers. We propose two AI distractor-generating methods for creating Chinese vocabulary items: semantic similarity and visual similarity. Semantic similarity refers to antonyms and synonyms, while visual similarity…

We examine the effects of computer-based versus paper-based assessment of critical thinking skills, adapted from English (in the U.S.) to Chinese. Using data collected based on a random assignment between the two modes in multiple Chinese colleges, we investigate mode effects from multiple perspectives: mean scores, measurement precision, item…

This study examined the impact of the manipulated task complexity (Robinson 2001a, 2001b, 2007, 2011; Robinson & Gilabert, 2007) on second language (L2) speech comprehensibility. I examined whether manipulated task complexity (a) impacts L2 speech comprehensibility, (b) aligns with L2 speakers' perception of task difficulty (cognitive…

A prerequisite for low-stakes activities to improve learning is to keep students engaged when confronted with challenging material. Comparing a personalized and non-personalized version of computerized practising, this study experimentally evaluates the relationships between student effort and ability across different dimensions of task…
