Mathematics word-problems continue to be an insurmountable challenge for many middle school students. Educators have used pictorial and schematic illustrations within the classroom to help students visualize these problems. However, the data shows that pictorial representations can be more harmful than helpful in that they only display objects or persons while neglecting the spatial relationships between those components (Hegarty & Kozhevnikov, p. 686). Research supports schematic diagrams that highlight spatial relationships and focus on related information within the problem (Hegarty & Kozhevnikov, 1999; van Garderen & Montague, 2003). In addition to these strategies, educators have used heuristics (systematic scripted procedures to solve word problems) as a way to provide structure and routine to a variety of word problems. This review of the literature found varying results for the use of some heuristics being implemented in present-day classrooms. On the other hand, both visual-spatial diagrams and heuristics have demonstrated value in middle school special education classrooms. These findings support the further use and research of visual-spatial representations and problem-solving heuristics in order to solve mathematics word problems.

With advancing technology, there is increasing interest in differences between listening versus reading comprehension or doing both simultaneously. Ninety-one participants were randomly assigned to one of three groups that received the same instructional material (the preface and a chapter from a non-fiction book), but each in a different input modality (digital audiobook, e-text, dual modality). After completing the material, participants took the same comprehension test in written form to establish both immediate comprehension (Time 1) and 2-week retention (Time 2). No statistically significant differences were found for any analyses pertaining to effects of the three different instructional conditions on comprehension at Time 1 or Time 2. Additional analyses showed that both males and females in each condition recalled an equal amount of information, regardless of whether they listened to an audiobook, read from an electronic tablet, or both listened and read simultaneously (dual modality).

While it is hypothesized that providing instruction based on individuals' preferred learning styles improves learning (i.e., reading for visual learners and listening for auditory learners, also referred to as the "meshing hypothesis"), after a critical review of the literature Pashler, McDaniel, Rohrer, and Bjork (2008) concluded that this hypothesis lacks empirical evidence and subsequently described the experimental design needed to evaluate the meshing hypothesis. Following the design of Pashler et al., we empirically investigated the effect of learning style preference with college-educated adults, specifically as applied to (a) verbal comprehension aptitude (listening or reading) and (b) learning based on mode of instruction (digital audiobook or e-text). First, participants' auditory and visual learning style preferences were established based on a standardized adult learning style inventory. Participants were then given a verbal comprehension aptitude test in both oral and written forms. Results failed to show a statistically significant relationship between learning style preference (auditory, visual word) and learning aptitude (listening comprehension, reading comprehension). Second, participants were randomly assigned to 1 of 2 groups that received the same instructional material from a nonfiction book, but each in a different instructional mode (digital audiobook, e-text), and then completed a written comprehension test immediately and after 2 weeks. Results demonstrated no statistically significant relationship between learning style preference (auditory, visual word) and instructional method (audiobook, e-text) for either immediate or delayed comprehension tests. Taken together, the results of our investigation failed to statistically support the meshing hypothesis either for verbal comprehension aptitude or learning based on mode of instruction (digital audiobook, e-text).
