This article discusses four functions of gesture that could promote thought processes: as a tool to ground knowledge through the visual system; enhance short-term and long-term memories; motor suppress irrelevant information. Gestures contribute grounding concepts metaphors describe abstract in terms visually perceivable concepts. In this way, at least some aspects concept be grounded system. m...

Food webs learning using the Snap! is one of strategies that are expected to help improve students' computational thinking. For students, this strategy were something new and can cause Extraneous Cognitive Load (ECL). The purpose study was identify ECL in food web develop thinking skills. research method used a pre-experimental design with modified from an iterative action design. sampling tech...

Our healthcare delivery system has accumulated complexity of payment, regulation systems, expectations and requirements. Often these are not designed to align with clinical thinking process flow patient care. As a result, clinicians utilizing enormous mental (cognitive) resource comply complexities, over above the baseline effort required give good care patient. Recent studies suggest significa...

Dictionary use can improve reading comprehension and incidental vocabulary learning. Nevertheless, great extraneous cognitive load imposed by the search process may reduce or even prevent the improvement. With the help of technology, dictionary users can now instantly access the meaning list of a searched word using a mouse click. However, they must spend great cognitive effort identifying the ...

We present the MUSHI (Multi-User Simulation with Handheld Integration) framework, which was designed to support middle and high school students in the acquisition of scientific concepts rooted in complex, multi-scalar phenomena. In designing a learning environment that is conducive to collaborative inquiry learning, we have combined a dynamic simulation with wirelessly-connected handheld device...

OBJECTIVE Individual meta-analyses were conducted for six training methods as part of a U.S. Army basic research project. The objective was to identify evidence-based guidelines for the effectiveness of each training method, under different moderating conditions, for cognitive skill transfer in adult learning. Results and implications for two of these training methods, learner control (LC) and ...

Over the past decade, immersive virtual environments have been increasingly used to facilitate students’ learning of complex scientific topics. The non-linearity and open-endedness of these environments create learning opportunities for students, but can also impose challenges in terms of extraneous cognitive load and greater requirements for self-regulated learning (SRL). SRL is crucial for ac...

When designing questionnaires for iPad an important design decision is whether to use popover listings or button listings for representing singlechoice selections. In this paper we examined effects of each listing method on performance and subjective preferences when performing a non-linear selection task. A quantitative experiment (N = 39) with the two within-factors (1) listing method (popove...
