Turkish course books and workbooks delivered to the second grade primary students are the most important course materials. The visual factors in these materials help the students know and understand the elements such as main theme, plot, scene, setting, characters and existence in a text. They help students develop their thoughts about the texts…

In this article, Miguel Aguilar describes the process of mental preparation he performs before beginning a new graffiti mural. This may include reviewing recent sketches and his lists of color palettes. Aguilar mind maps ideas he wants to connect, thinking about intentions or the goal he wants to accomplish. Aguilar further states "this…

As we turn more and more to high-end computing to understand the Universe at cosmological scales, dynamic visualizations of simulations will take on a vital role as perceptual and cognitive tools. In collaboration with the Adler Planetarium and University of California High-Performance AstroComputing Center (UC-HiPACC), I am interested in better…

This article reports an innovative use of photographs in a pencil-and-paper test which was developed to assess young children's understanding of mass measurement. Two hundred and ninety-five tests were administered by thirteen teachers of Years 1 and 2 children in 3 urban and rural schools. Many of these children of 6-8 years of age were able to…

Three-dimensional (3D) object completion, the ability to perceive the backs of objects seen from a single viewpoint, emerges at around 6 months of age. Yet, only relatively simple 3D objects have been used in assessing its development. This study examined infants' 3D object completion when presented with more complex stimuli. Infants…

This study intends to investigate how multi-symbolic representations (text, digits, and colors) could effectively enhance the completion of co-located/distant collaborative work in a virtual reality context. Participants' perceptions and behaviors were also studied. A haptics-enhanced virtual reality task was developed to conduct…

The work described here represents an effort to understand and influence visual attention while solving physics problems containing a diagram. Our visual system is guided by two types of processes--top-down and bottom-up. The top-down processes are internal and determined by ones prior knowledge and goals. The bottom-up processes are external and…

The purpose of this study was to investigate the relationship between a collaborative design process for selecting instructional graphics and online learner perceptions of graphic appropriateness. At the end of their online graduate course, 9 students ranked how appropriately each of 25 graphics represented 1 of 8 human performance technology…

Educational software systems have an increasingly significant presence in engineering sciences. They aim to improve students' attitudes and knowledge acquisition typically through visual representation and simulation of complex algorithms and mechanisms or hardware systems that are often not available to the educational institutions. This paper…

This study was designed according to the mixed research method in which quantitative and qualitative research methods were used in order to identify the challenges confronted by classroom teacher candidates in solving mathematical problems and the factors affecting how they choose these representations. The population of this study consisted of…

Context: Plastination techniques have emerged as effective methods for preserving human tissue and enabling human specimens to be utilized in a fashion similar to anatomical models with much greater accuracy. Opportunities to observe and experience human specimens in classroom settings should be beneficial to undergraduate and graduate students in…

Working with elementary students with disabilities, we used alternating treatment designs to evaluate and compare the effects of 2 computer-based flash card sight-word reading interventions, 1 with 1-s response intervals and another with 5-s response intervals. In Study 1, we held instructional time constant, applying both interventions for 3?min.…

In this paper we present a study on the difficulties secondary school students experience in interpreting textbook images of elementary astronomical phenomena, namely, the changing of the seasons, Sun and lunar eclipses and Moon phases. Six images from a commonly used textbook in Italian secondary schools were selected. Interviews of 45 min about…

The complementary use of the theories of instrumental genesis and shifts of attention enabled me to obtain insights into students' understandings of the concepts of eigenvector and eigenvalue. My analysis suggests that the use of different dragging modalities can provide evidence of shifts in structure of a student's attention and consequently can…

This article examines the literacy events in HIV/AIDS education in Tanzania to investigate how they construct social identities for participants and to what extent they provide opportunities for critical health literacies. The projects took place as collaborative research partnerships with local Tanzanian NGOs in an effort to analyse and improve…
