A latent variable modeling approach for scale reliability evaluation in heterogeneous populations is discussed. The method can be used for point and interval estimation of reliability of multicomponent measuring instruments in populations representing mixtures of an unknown number of latent classes or subpopulations. The procedure is helpful also…

There is no question that a thorough knowledge and understanding of the gross architecture of the human body underlies sound medical practice and, therefore, comprises an early curricular goal. Thus, the exploration of palpable human anatomy in the dissection laboratory addresses the pivotal goal of establishing a comprehension of the three…

Structural equation mixture models (SEMMs), when applied as a semiparametric model (SPM), can adequately recover potentially nonlinear latent relationships without their specification. This SPM is useful for exploratory analysis when the form of the latent regression is unknown. The purpose of this article is to help users familiar with structural…

In this article, a latent trait model is proposed for the response times in psychological tests. The latent trait model is based on the linear transformation model and subsumes popular models from survival analysis, like the proportional hazards model and the proportional odds model. Core of the model is the assumption that an unspecified monotone…

Momentary time sampling (MTS), whole interval recording (WIR), and partial interval recording (PIR) are commonly used in applied research. We discuss potential difficulties with analyzing data when these systems are used and present results from a pilot simulation study designed to determine the extent to which these issues are likely to be…

Memories that last a lifetime are thought to be stored, at least in part, as persistent enhancement of the strength of particular synapses. The synaptic mechanism of these persistent changes, late long-term potentiation (L-LTP), depends on the state and number of specific synaptic proteins. Synaptic proteins, however, have limited dwell times due…

Teachers are being challenged to engage students in ways that will elevate student interest and understanding of concepts in science and encourage students to gather evidence to support what we know about science. It is critical for teachers to have budget-friendly, supporting activities that are aligned with current educational standards, that…

The need for hands-on learning in advertising education has been expressed for decades. With the increasing push toward live tweeting by brands, more attention needs to be given in advertising classrooms to opportunities for students to practice online engagement. In this study, a class "war room" simulation offered an experiential…

According to the most recent data from the federal Chemical Safety and Hazard Investigation Board, between 2001 and 2011, more than 120 university laboratory accidents have caused injuries (including one death) and millions of dollars in damages. Laboratory-safety lessons normally comprise lecture slides alongside occasional movies and tours of…

In this paper, we present a flexible full-information approach to modeling multiple userdefined response styles across multiple constructs of interest. The model is based on a novel parameterization of the multidimensional nominal response model that separates estimation of overall item slopes from the scoring functions (indicating the order of…

This design case describes the work involved in developing a digital game-based learning environment, work that was part of a PhD research project. The designer was involved in all aspects of the project: conducting research into content that was included in the game, exploring the gaming platform (Second Life), adapting scientific literature for…

The purpose of this study was to determine if students learn clinical judgment as effectively using computer-based simulations as when using high-fidelity mannequin simulations. There was a single research questions for this study: What is the difference in clinical judgment between participants completing high-fidelity human simulator mannequin…

This activity report describes two cases of Language teaching for degree students in the University of Oulu with new pedagogical approaches aiming towards authentic working life skills. Co-creation, collaborative learning and cooperation across borders are the building blocks for these innovative language teaching projects. Case 1 describes…

Digital technologies are an integral part of Higher Education teaching, revealing a set of technologies chosen to integrate formal learning contexts, and therefore being used by students in support of learning. This paper presents a literature review mapping the digital technologies set for higher education students to use in formal education…

This text presents the results of surveys and interviews of Former Students (FSs) who have taken part in a teacher education course that began in 2004 (still on-going) and that includes Virtual Exchange (VE). The study aimed to look at the impact of two teacher education courses, imparted collaboratively between geographically-distanced…
