In the contemporary higher education system there is growing interest in, and debate about, the need to strengthen and sustain the relationships between teaching and research. While there are multiple and varied explanations about these relationships, most acknowledge the importance of designing learning activities that explicitly develop the…

Multi-indicator growth models were formulated as special three-level hierarchical generalized linear models to analyze growth of a trait latent variable measured by ordinal items. Items are nested within a time-point, and time-points are nested within subject. These models are special because they include factor analytic structure. This model can…

This study investigated the use of computer-based intervention for enhancing communication functions of children with autism. The software program was developed based on daily life activities in the areas of play, food, and hygiene. The following variables were investigated: delayed echolalia, immediate echolalia, irrelevant speech, relevant…

To deal with nonnormal and heterogeneous data for the one-way fixed effect analysis of variance model, the authors adopted a trimmed means method in conjunction with Hall's invertible transformation into a heteroscedastic test statistic (Alexander-Govern test or Welch test). The results of simulation experiments showed that the proposed technique…

Three experiments investigated the route-angularity effect, which is demonstrated when a greater number of turns along a route increases the estimated length. So far, a route-angularity effect has not been demonstrated in school-age children. Because of the lack of a developmental theory, this finding could only be explained by a minor control of…

A teaching--learning sequence is presented that is designed to help high school pupils gain awareness about the independence of the vertical and horizontal components of free fall motion. The approach we propose is based on the use of experimental activities and computer simulations designed specifically to help pupils reflect on the experiments…

Laboratory classes are commonplace and essential in biology departments but can sometimes be cumbersome, unreliable, and a drain on time and resources. As university intakes increase, pressure on budgets and staff time can often lead to reduction in practical class provision. Frequently, the ability to use laboratory equipment, mix solutions, and…

When dealing with a complex problem, solving it by reduction to simpler problems, or problems for which the solution is already known, is a common method in mathematics and other scientific disciplines, as in computer science and, specifically, in the field of computability. However, when teaching computational models (as part of computability)…

The present study examined if spatial knowledge gained from a virtual environment is affected by the spatial ability of the participant, and whether information can be more efficiently acquired and applied to a physical space when participants are given a display featuring both overhead and first-person visual cues. Three spatial training displays…

The emphasis of most simulations in chemical engineering education seems to be on teaching students how to use simulations to solve typical engineering problems. The authors have found little evidence of simulations being explicitly used to develop conceptual understanding, and therefore sought to investigate their potential use in this regard. In…

This article describes a university-sponsored experiential-based simulation, the NANO SCENARIO, to increase the public's awareness and affect attitudes on the societal implications of nanoscience and nanotechnology by bringing together diverse stakeholders' perspectives in a participatory learning environment. Nanotechnology has the potential for…

In this paper, I review both mathematics education and CSCL literature and discuss how we can better take advantage of CSCL tools for developing mathematical proof skills. I introduce a model of proof in school mathematics that incorporates both empirical and deductive ways of knowing. I argue that two major forces have given rise to this…

Two major obstacles to using problem-based learning methods with writing in elementary school classrooms are the time it takes to design the learning environment and the time required for students to interact at their own pace with ill-structured problems used to spur student writing. This study examined whether game elements could be used along…

This article discusses our teaching approach in graduate level Engineering Statistics. It is based on the use of modern technology, learning groups, contextual projects, simulation models, and statistical and simulation software to entice student motivation. The use of technology to facilitate group projects and presentations, and to generate,…

This study sought to determine the effect of simulation-games environment on students' achievement in attitudes to mathematics in secondary school. Data was collected from a sample of 147 students in senior secondary school in Osun-State, Nigeria. t-test and analysis of variance was used to analyze the data collected for the study. The finding…
