Purpose: Although a growing body of literature has identified the positive effects of visual speech on speech and language learning, oral movements of infant-directed speech (IDS) have rarely been studied. This investigation used 3-dimensional motion capture technology to describe how mothers modify their lip movements when talking to their…

How do external visual representations (e.g., graph, diagram) promote or constrain students' ability to identify system components and their interrelations, to reinforce a systemic view through the application of the STS approach? University students (N = 150) received information cards describing cellphones' communication system and its subsystem…

This study explores how a group of nine year olds in Korea form historical inferences using pictures of historical paintings. It investigates whether they have the ability to form plausible inferences about the lives of people depicted in these pictures, what they can infer about the lives of people depicted in the pictures using prior knowledge,…

Verbal protocols have provided literacy researchers with a strong understanding of what processes readers (both adults and children) use as they read narrative and informational text. Little is known, however, about the comprehension processes that are prompted by the graphics in these texts. This study of nine second graders used verbal protocol…

Visual representations are ubiquitous in modern-day science textbooks and have in recent years become an object of criticism and scrutiny. This article examines the extent to which changes in representations in textbooks published in the USA over the past six decades have invited those critiques. Drawing from a correlational analysis of a corpus…

Many lecture halls today have two or more screens to be used by instructors for lectures with computer-supported visual aids. Typically, this additional screen real estate is not used to display additional information; rather a single stream of information is projected on all screens. We describe a controlled laboratory study that empirically…

Three picture-word interference experiments addressed the question of whether the scope of grammatical advance planning in sentence production corresponds to some fixed unit or rather is flexible. Subjects produced sentences of different formats under varying amounts of cognitive load. When speakers described 2-object displays with simple…

A pretest-posttest comparison group design was used to investigate the effects of a semantic mapping lesson plus visual display versus a semantic mapping lesson alone on adolescents' with learning disabilities (LD) ability to gain and maintain factual knowledge from expository social studies material. In addition, a posttest only comparison group…

This paper proposes a model of effective instruction and intervention for English Learners (ELs) within a Response to Intervention (RTI) framework. First, we review literature on effective instruction for ELs and how RTI can address the needs of these students. Then, we describe the PLUSS model, which integrates research on effective instruction…

This project provides a comprehensive overview of the research literature on problem gambling in adults and includes a detailed mindfulness-based psychoeducational group manual for problem gambling, complete with an extensive group counselling consent form, assessment and screening protocols, 10 user-friendly lesson plans, templates for a…

Many studies have stressed students' lack of understanding of experiments in laboratories. Some researchers suggest that if students design all or parts of entire experiment, as part of an inquiry-based approach, it would overcome certain difficulties. It requires that a procedure be written for experimental design. The aim of this paper is to…

Good learning experiences ask students to investigate and make sense of the world. While there are many ways to do this, K-12 curriculum has traditionally skewed toward reading and writing to interpret and express students' sense-making. But there is another way. Infographics represent data and ideas visually, in pictures, engaging more parts of…

This paper reports on a project aimed at identifying and exploring the development and implementation processes of teaching practices with interactive whiteboards (IWBs) in two Swedish K-6 schools. The purpose of the project was to generate results and insights of value when preparing student teachers for professional use of IWBs and to give…

This protocol guided the review of research that informed the recommendations contained in the What Works Clearinghouse (WWC) practice guide "Improving Mathematical Problem Solving in Grades 4 through 8," published in May 2012. The research review involved the following steps: (1) The research staff searched the professional literature…

This article presents the author's comments on Robin Kelsey's "Archive Style: Photographs and Illustrations for U.S. Surveys, 1850-1890," a book about government documents that happen to be visual materials. The word "archive" now has intellectual cache in the academic world, but its currency has little to do with the…
