All cognitive diagnostic models that evaluate educational test data require a Q-matrix that combines every item in a test with the required cognitive skills for each item to be answered correctly. Generally, the Q-matrix is constructed by education experts' judgment, leading to some uncertainty in its elements. Various statistical methods are…

Concerns about environmental sustainability are constantly in the news as global warming, fossil fuels, and pollutants increasingly endanger habitats worldwide. What once were uncommon extreme environmental events have become commonplace--unseasonal intense heat, year-round drought, raging wildfires, rising sea levels, severe storms, massive…

The aim of this study is to evaluate the effects of a teaching simulation activity that uses a chatbot on preservice teachers' efficacy. Forty-six preservice teachers were asked to teach the chatbot the topic of school violence and how to handle it. They were assigned to one of three groups: Teaching a chatbot whose attitude was impolite, polite,…

Equilibrium is a challenging concept for many, largely because developing a deep conceptual understanding of equilibrium requires someone to be able to connect the motions and interactions of particles that cannot be physically observed with macroscopic observations. Particle level chemistry animations and simulations can support student…

When fitting unidimensional item response theory (IRT) models, the population distribution of the latent trait ([theta]) is often assumed to be normally distributed. However, some psychological theories would suggest a nonnormal [theta]. For example, some clinical traits (e.g., alcoholism, depression) are believed to follow a positively skewed…

Longitudinal data analysis has been widely employed to examine between-individual differences in within-individual changes. One challenge of such analyses is that the rate-of-change is only available indirectly when change patterns are nonlinear with respect to time. Latent change score models (LCSMs), which can be employed to investigate the…

Context: Emergency and immediate care skills are often difficult to practice in real time during clinical education. One immediate care skill requiring advanced training that may not be implemented during clinical education is wound closure via suturing. Simple laceration management with sutures can be advantageous skill for athletic training…

Recently, simulation-based learning (SBL) has become an inseparable part of teacher-education. This case study examined the learning processes that preservice teachers experienced while participating in SBL. The main goal of the study was to identify the aspects of peer learning inherent to SBL that are beneficial for the teacher-education…

The study has chosen perhaps the most well-known serious game in the field of supply chain management: The Beer Game, and uses the means-end chains theory in an attempt to explore the innovative attributes that learners may wish to experience while playing. The study will also construct the psychological hierarchical structure of "innovative…

Molecular-, fluid- and field-dynamics simulation are becoming more mainstream tools for practicing process engineers; here, the academic community needs to pay close attention to "upskilling" demands from industry, where remote working/training emphasizes the need for sophisticated computational-engineering design tools with molecular…

Experimental studies of educational interventions are rarely based on representative samples of the target population. This simulation study tests two formal sampling strategies for selecting districts and schools from within strata when they may not agree to participate if selected: (1) balanced selection of the most typical district or school…

Workshop 2 explores some larger vocabulary networks than those presented in Workshop 1 (1,000 words instead of 100), and introduces some additional ways of activating words in a network (e.g., by using new parameters in our models). The simulations will show that raising a network's activation level may not be as easy as we would have expected,…

The idea that a vocabulary is a network of words is one that has become a common theme of the second language (L2) vocabulary research literature. However, not many people have considered the wider implications of this powerful metaphor. This paper is the first in a series of workshops that examines some of these implications. In this first…

Entrepreneurship education has historically been part of agricultural education; yet few researchers have studied entrepreneurship-related outcomes for youth in formal and nonformal educational settings. Entrepreneurship education programs develop entrepreneurial attitudes and intentions, but limited studies exist regarding junior high school…

Proteins are "magical" workers inside our body, as they accomplish most of the cellular functions. Here we report on a novel approach to teach protein folding and unfolding, using magnets and flexible 3D-printed protein structures. To illustrate this physical process, we used colored circular magnets designed for whiteboards, connected…
