We propose an apparatus that emulates the experiment used by Geiger and Marsden in 1913 to investigate alpha particles (Rutherford) scattering. Using a widely available fused deposition modelling 3D-printer, we built a compartmented and easily assembled educational instrument. The whole apparatus is composed of a 3D-printed chamber and an…

We investigated the characteristics of a medical simulation-based informal learning environment (MSBE) of a science center--an environment not yet studied--to understand its uniqueness and its impact on visiting students. In the MSBE, students interact with, and operate, sophisticated simulators which demonstrate a range of medical situations.…

Human operators often experience large fluctuations in cognitive workload over seconds timescales that can lead to sub-optimal performance, ranging from overload to neglect. Adaptive automation could potentially address this issue, but to do so it needs to be aware of real-time changes in operators' spare cognitive capacity, so it can provide help…

Objective: A lack of movement in adolescence is a pressing issue for modern society. Physical education at school can have a major influence on the movement habits of adolescents, since it can offer curriculum that gives students ideas for leisure time while entertaining them and also respecting physical fitness goals. The aim of this work is to…

The large introductory classes at many universities present a particular challenge for instructors wishing to guarantee participation opportunities for their students. Yet, large courses can actually afford advantages for instructors looking to replicate many features of the U.S. Congress. We describe two separate Congressional simulations in an…

In learning diagnostic assessments, the attribute hierarchy specifies a sequential network of interrelated attribute mastery processes, which makes a test blueprint consistent with the cognitive theory. One of the most important functions of attribute hierarchy is to guide or limit the developmental direction of students and then form a…

Because of their presumably familiar plot lines and character tropes, the Grimm Brothers' fairy tales are often included as one of the earliest literary selections in German language and culture curricula. However, for learners to engage more critically and interpretively with fairy-tale genres, it is exactly their assumed familiarity with the…

Across languages, children map words to meaning with great efficiency, despite a seemingly unconstrained space of potential mappings. The literature on how children do this is primarily limited to spoken language. This leaves a gap in our understanding of sign language acquisition, because several of the hypothesized mechanisms that children use…

Purpose: Simulated competition as a training tool has a relevant role in enhancement of exercise intensity, motivation and physical enjoyment. Including a competitive component into the agility training could represent another way to improve agility performance significantly more. The aim of this study was to assess the effect of agility training…

Courses: Crisis Communication, Crisis and Issue Management, Writing for Public Relations, Public Relations Capstone. Objective: This unit activity refines traditional simulation activities used in crisis communication education. By partnering with crisis management professionals and developing localized, multi-stage scenarios grounded in the…

Educational researchers are often interested in phenomena that unfold over time within a person and at the same time, relationships between their characteristics that are stable over time. Since variables in a longitudinal study reflect both within- and between-person effects, researchers need to disaggregate them to understand the phenomenon of…

This qualitative descriptive study investigated the self-efficacy of nurse practitioner (NP) instructors after completion of an online course on simulation pedagogy. Due to minimum standards for NP instructors to have a degree as either a NP or be considered an expert in their content field, most of them do not have formalized education in the…

Clinical judgment is defined as an understanding and interpretation regarding patient's needs, health problems or concerns (Tanner, 2006). There are four interrelated processes in Tanner's model that consist of noticing, interpreting, responding, and reflecting (Tanner, 2006). Because clinical judgment is extremely complex and encompasses many…

The forced-choice (FC) item formats used for noncognitive tests typically develop a set of response options that measure different traits and instruct respondents to make judgments among these options in terms of their preference to control the response biases that are commonly observed in normative tests. Diagnostic classification models (DCMs)…

Assessing the measurement model (MM) of self-report scales is crucial to obtain valid measurements of individuals' latent psychological constructs. This entails evaluating the number of measured constructs and determining which construct is measured by which item. Exploratory factor analysis (EFA) is the most-used method to evaluate these…
