This article describes how the author has developed tasks for students that address the missed "essence of the matter" of algebraic transformations. Specifically, he has found that having students practice "perceiving" algebraic structure--by naming the "glue" in the expressions, drawing expressions using…

Semantic studies on diagrammatic notations (Barwise & Etchemendy,; Shimojima,; Stenning & Lemon, ) have revealed that the "non-deductive," "emergent," or "perceptual" effects of diagrams (Chandrasekaran, Kurup, Banerjee, Josephson, & Winkler,; Kulpa,; Larkin & Simon,; Lindsay, ) are all rooted in the…

Several contributions in "Biochemistry and Molecular Biology Education" have highlighted the role of visualization tools and the importance of developing students' visual literacy in biochemistry education. In this forum, the authors suggest that more focus is needed on the assessment of student learning, and they advance…

To test general and specific processes of symbol learning, 4- and 5-year-old children learned three kinds of abstract associates for novel objects: words, facts, and pictograms. To test fast mapping (i.e., one-trial learning) and subsequent learning, comprehension was tested after each of four exposures. Production was also tested, as was…

The use of two-dimensional (2D) representations to communicate and reason about micromolecular phenomena is common practice in chemistry. While experts are adept at using such representations, research suggests that novices often exhibit great difficulty in understanding, manipulating, and translating between various representational forms. When…

In recent years, chewing has been discussed as producing effects of maintaining and sustaining cognitive performance. We have reported that chewing may improve or recover the process of working memory; however, the mechanisms underlying these phenomena are still to be elucidated. We investigated the effect of chewing on aspects of attention and…

Many modern theories propose that perceptual information is represented by the sensorimotor activity elicited by the original stimulus. Scanpath theory (Noton & Stark, 1971) predicts that reinstating a sequence of eye fixations will help an observer recognize a previously seen image. However, the only studies to investigate this are…

Information technology has played several important roles in group decision making, such as communication support and decision support. Little is known about how information technology can be used to persuade members of a group to reach a consensus. In this dissertation, I aim to address the issues that are related to the role of visual…

The study of student representation use and specifically the distinction between analytic and visual representations has fueled a long line of mathematics education literature that began more than 35 years ago. This literature can be partitioned into two bodies of work, one that is primarily cognitive and one that is primarily social. In spite of…

This study examined undergraduate and graduate students' perceptions of the impact of in-class learning activities, out-of-class learning activities, and instructional materials on their learning. Using survey methodology, students anonymously assessed their perceptions of in-class activities, out-of-class activities, and instructional materials…

This study offers an investigation of three graduate-level SoTL programs offered since 2007 at a mid-size, highly selective, private, research-intensive university in the southeastern United States. We identify patterns in these early experiences with the scholarship of teaching and learning, specifically the choices made while carrying out their…

This study examined the effects of a graphic organizer intervention package on the quality and quantity of persuasive writing of three middle school students with Autism Spectrum Disorder (ASD). The intervention included a 3-day training which consisted of explicit instruction on the components of a persuasive essay, modeling and guided practice…

The purpose of this research was to identify commonly used interactive webinar software platforms and to conduct a testing session on best practices related to an interactive webinar. The study employed the Adobe Connect and the Maestro Conference platforms. The 15 participants experienced five best practices: pre-work, polling, breakout room,…

Native speakers of alphabetic languages, which use letters governed by grapheme-phoneme correspondence rules, often find it particularly challenging to learn a logographic language whose writing system employs symbols with no direct sound-to-spelling connection but links to the visual and semantic information. The visuospatial properties of…

Do your students think a triangle can be constructed from any three given line segments? Do they believe that a transformation affects only the pre-image--not the whole plane? Do they understand that examples--no matter how many they find--cannot prove a conjecture but one counterexample is sufficient to disprove it? "What tasks can you…
