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…

This was a simple classroom research project and its purpose was to examine how high up in the scale of Bloom's taxonomy students were able to reach to understand higher order thinking skills when studying critical thinking questions. Two classes of senior high school students who had been studying in the same bilingual program for five years were…

There is an assumption that pedagogical content knowledge (PCK) is observable and measurable. Yet, in many studies referencing PCK, the construct of PCK remains both undefined operationally and poorly described. In physical education, although one study has measured teachers' PCK using teachers' weak and strong units of instruction (Ayvazo, 2007),…

Educational practices are needed to promote strong vocabulary growth so that vocabulary can be both the cause and result of successful reading. Vocabulary interventions need to begin early and continue for a sustained period of time (Beck & McKeown, 2007a; Biemiller, 2003; Foorman, Seals, Anthony & Pollard-Durodola, 2003). According to theoretical…

This book is about the classroom, the most important meeting place for teachers and pupils in an education building. Individuals' knowledge, however, about what happens inside this space is limited. In many respects the classroom is still the black box of the educational system. To open up this box, this volume brings together scholars from the…

There is much discussion today about the need to transform higher education. Experts and researchers list numerous challenges: low student retention and graduation rates, the increasing cost of higher education, and concerns that graduates don't possess the skills required to compete successfully in today's interconnected, global marketplace.…

This study analyzes the potential of major financial aid initiatives to serve as key elements of an institutional branding strategy. Concepts of branding and marketing serve as guiding frameworks for the analysis and interpretation of the findings. Using a case study approach, data were collected through interviews and document analysis at the…

This study investigated the effectiveness of an instructional program (schema-based instruction, SBI) designed to teach 7th graders how to comprehend and solve proportion problems involving ratios/rates, scale drawings, and percents. The SBI program emphasized the underlying mathematical structure of problems via schematic diagrams, focused on a…

This article is the result of a study carried out in 2008 and 2009 by a team from the Autonomous University of Barcelona in order to evaluate the implementation of the Digital Whiteboard Program in public schools in the region of Aragon (Spain). The following pages present some of the results obtained during the study. More specifically, this…

Purpose: Communication about feelings is a core element of human interaction. Aided augmentative and alternative communication systems must therefore include symbols representing these concepts. The symbols must be readily distinguishable in order for users to communicate effectively. However, emotions are represented within most systems by…
