Although student covariation reasoning has been explored in depth to improve understanding of the correspondence between variables, research has focused on studying existing reasoning about variables in Cartesian representations. The working method had a qualitative approach, with a descriptive exploratory scope, the spontaneous representations…

It is widely acknowledged that communicating mathematical thinking is complex, difficult, and often messy. In this article, the authors explore how mathematical thinking is communicated, providing examples of strategies for teachers and students to use in the mathematics classroom.

The present work presents a proposal for study and investigation, in the context of the teaching of Mathematics, through the history of linear and recurrent 2nd order sequences, indicated by: Fibonacci, Lucas, Pell, Jacobsthal, Leonardo, Oresme, Mersenne, Padovan, Perrin and Narayana. Undoubtedly, starting from the Fibonacci sequence, representing…

Nowadays, knowledge dissemination among children is no longer limited to the classroom and course or information books. It also includes websites explicitly addressed to youngsters who have a different stage of cognitive development and background knowledge compared to adults. However, they are also the first to live in today's multimodal…

Many researchers, teacher educators, teachers and students view graphics in text as an aspect of student learning (e.g. engagement, comprehension). However, as a field we have not addressed teachers' pedagogical content knowledge and decision-making associated with the use of graphics, student learning and issues of access. This mixed methods…

Middle school teachers tend to rely heavily on texts that have become increasing more visual. There is little information available about the graphical demands of general middle grades' science texts. The purpose of this study was to quantify the type and quality of the graphical representations and how they interacted with the textual material in…

Graphing is an integrative skill because you can use it whether you are teaching measurement or geometry or number theory or most any other topic. It is also important as a mode of communication which can simplify a large amount of information. Here are five steps for effective presentation of graphing to young students. (Author/RK)

Describes a number of methods of teaching graphing and in fulfilling objectives in graphing such as collecting data from the student's immediate environment and using standard graphical practice in representing relationships. (Author/RK)

A study examined the effect of using graphic organizers (GOs) with 24 middle school students with learning disabilities to convey and cue relational knowledge. On written essays that required application, the GOs group provided significantly more relational knowledge statements than students in the group without GOs. (Contains references.)…

Perhaps because the United States is undergoing a video revolution, perhaps because of its increasing sales of goods to non-English speaking markets where graphics can help explain the products, perhaps because of the decreasing communication skills of the work force, graphic aids are becoming more and more widely used and more and more important.…

Examples of the use of hieroglyphics (glyphs) in science and medicine are presented. Suggests having academically talented science students use glyphs to make their own pictorial representations of their own data. (JN)

Uses the process of normalization in the Cartesian coordinate system which entails radial projection onto a transect to compare different compositions of minerals. Warns that the ternary diagram should not be used as a framework for calculations. (MVL)

This paper stresses the unified nature of the Languages for Special Purposes (LSP) operation, and argues for increased research at every phase. It deals specifically with the following topics: (1) a procedural ESP model in which the ESP activity is conceived of as a whole, and the various stages in the planning and mounting of an ESP program are…

This research compared the performance of ninth grade females and males on flight protocol, with particular attention to interpretation of the graphs of paths of falling bodies, rolling objects, and projectiles. These subjects were chosen because they had received no formal instruction in projectile motion, yet through typical life experience, had…
