Understanding fraction magnitudes is foundational for later math achievement. To represent a fraction "x/y," children are often taught to use "partitioning": break the whole into "y" parts, and shade in "x" parts. Past research has shown that partitioning on number lines supports children's fraction…

Understanding fraction magnitudes is foundational for later math achievement. To represent a fraction x/y, children are often taught to use "partitioning": Break the whole into y parts and shade in x parts. Past research has shown that partitioning on number lines supports children's fraction magnitude knowledge more than partitioning on…

The objective of this work was to evaluate the implementation of a metavisual strategy for students to revise and self-regulate concepts arising in a study of a chemical reaction between ions. For this purpose, two chemistry education undergraduate students at a Brazilian public university carried out an investigative activity, involving…

Instruction in most STEM domains uses visuals to illustrate complex problems. During problem solving, students often manipulate and construct visuals. Traditionally, students draw visuals on paper and receive delayed feedback from an instructor. Educational technologies have the advantage that they can provide immediate feedback on students'…

Visualizations and visual models are of substantial importance for science learning (Harrison and Treagust, 2000), and it seems impossible to study chemistry without visualizations. More specifically, the combination of visualizations with text is especially beneficial for learning when dual coding is fostered (Mayer, 2014). However, at the same…

Several studies related to mathematical proof have been done by many researchers on high-level materials, but not yet examined on the material of transformation geometry. The aim of this research is identification learning obstacles pre-service teachers on transformation geometry. This study is qualitative research; data were collected from…

Launching a problem is critical in a problem-based lesson. We investigated teachers' perspectives on the use of a problem that was analogous to the one provided during a launch. Our goal was to identify teachers' underlying assumptions regarding what should constitute a launch as elements of the "practical rationality of mathematics…

Multiple studies report that Computer Science (CS) instructors face problems on how to integrate visualizations in their teaching. This problem gets compounded for instructors in technology-constrained classrooms that are common in developing countries. In these classrooms, students are not able to interact with visualization directly; instead,…

The purpose of the study was to investigate the effects of imagination and learner-generated drawing on comprehension, reading time, cognitive load, and eye movements, and whether prior knowledge moderated the effects of these two strategies. Sixty-three undergraduate students participated in a pretest-posttest between-subjects study with the…

In this new edition of their groundbreaking book "Strategies That Work," Stephanie Harvey and Anne Goudvis share the work and thinking they've done since the second edition came out a decade ago and offer new perspectives on how to explicitly teach thinking strategies so that students become engaged, thoughtful, independent readers.…

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…

This study utilizes theory from situated cognition to investigate faculty beliefs about student learning and their influence on teaching decisions. Results of interviews with and observations of 56 science and math faculty found that the two most common beliefs are: (a) students learn best through repeated practice, and (b) students have different…

Students are frequently presented with novel visualizations introducing scientific concepts and processes normally unobservable to the naked eye. Despite being unfamiliar, students are expected to understand and employ the visualizations to solve problems. Domain experts exhibit more competency than novices when using complex visualizations, but…

This article reviews theoretical and research evidence to support the explicit and systematic teaching of five comprehension strategies that will help all students tackle expository texts with success. The article explains the "High 5!" strategies and how to teach them. An example of a lesson is included to show how the five strategies connect…
