Research and pedagogical information provided to teachers on implementing explicit strategy instruction has primarily focused on teachers' speech, with limited attention to other modes of communication, such as gesture and artefacts. This interpretive case study investigates two teachers' use of different semiotic resources when introducing…

The importance of mathematical visual images is indicated by the introductory paragraph in the Statistics and Probability content strand of the Australian Curriculum, which draws attention to the importance of learners developing skills to analyse and draw inferences from data and "represent, summarise and interpret data and undertake…

The Common Core State Standards Initiative stresses the importance of developing a geometric and algebraic understanding of complex numbers in their different forms (i.e., Cartesian, polar and exponential). Unfortunately, most high school textbooks do not offer such explanations much less exercises that encourage students to bridge geometric and…

This study examines the relationship between community college enrollment patterns and student outcomes--credential completion and transfer to a 4-year institution--introducing a new way of visualizing the various attendance patterns of community college students. Patterns of enrollment intensity (full- or part-time status) and continuity…

There were two purposes in the study. One was to explore the cognitive activities during spatial problem solving and the other to probe the relationship between spatial ability and science concept learning. Twenty university students participated in the study. The Purdue Visualization of Rotations Test (PVRT) was used to assess the spatial…

This paper describes a technique for locating indicators of success within the data collected from complex learning environments, proposing an application of e-research to access learner processes and measure and track group progress. The technique combines automated extraction of tense and modality via parts-of-speech tagging with a visualisation…

Efforts to make effective use of technology offer a promising direction for science education research. In this study, we investigated how a teacher and students used an inquiry-based, visualization-focused chemistry unit. The chemistry unit was designed for American students and takes advantage of dynamic, interactive computer visualizations.…

In the late 1970's, Durkin's landmark study showed that less than 1% of elementary classroom reading instruction was dedicated to comprehension strategies because teachers were not explicit in their instruction. This qualitative study explored the types of questions posed by elementary and middle school teachers to elicit students' responses and…

Co-thought gestures are hand movements produced in silent, noncommunicative, problem-solving situations. In the study, we investigated whether and how such gestures enhance performance in spatial visualization tasks such as a mental rotation task and a paper folding task. We found that participants gestured more often when they had difficulties…

Despite the fact that to date Visual Literacy (VL) scholars have not arrived at a general consensus for a theoretical organization of the VL field, important conceptual investigations have emerged over the past four decades. In this paper we discuss and synthesize those studies. We then present a first attempt toward a cohesive theory of VL. The…

Case-based instruction (CBI) offers a promising method for promoting problem-solving skills in learners. However, during CBI, the instructor shoulders major responsibility for shaping the learning that takes place. Research indicates that the facilitation techniques used during case discussions influence what gets covered, and to what extent,…

The relevance of the investigated problem is caused by the fact that most children who start to study do not have a good level of higher mental functions. It leads to difficulties at school and health problems. The article aims at estimating the level of higher mental functions and the degree of educational motivation development among…

The purpose of this research is to develop a hands-on spatial geometry learning system to facilitate the learning of geometry. The development of this system was based on Duval's four critical elements of geometric learning: perceptual apprehension, sequential apprehension, operative apprehension, and discursive apprehension. The system offers…

Through a series of interviews, I learned how my father drew upon his family's and community's teachings, which were deeply rooted in traditional Haida pedagogy, to achieve success. I reflected on his stories and their connections and the work of other Indigenous scholars in the field of education to thematically organize the teachings that he…

The teacher has very important roles in the classroom, particularly as manager of most resources for learning activities and in providing timely feedback that can enhance learning. But teachers need to be aware of students' achievements and weaknesses to decide how to time feedback. We present MTFeedback, a system that harnesses the new…
