A range of characteristics of learners is described and their relationship to working memory discussed in the context of teaching and learning in the sciences. The characteristics are extent of field dependency, visual spatial abilities, divergency and convergency. These learner characteristics were measured for a large sample of school pupils…

Using the structure of a metacognitive journal, this article describes the author's discovery of an unusual method for adding fractions after carefully considering a student's response. (Contains 3 figures.)

Within the cognitive load theory framework, we designed and compared three alternative instructional solution formats that can be derived from a common static hierarchical network representation depicting problem structure. The interactive-solution format permitted students to search in self-controlled manner for solution steps, static-solution…

To date, research involving homemade PowerPoint games as an instructional tool has not shown statistically significant gains in student performance. This paper examines the results of a study comparing the performance of students in a high school chemistry course who created homemade PowerPoint games as a test review with the students who used a…

Two studies examined the role of intention in preschoolers' understanding of teaching. Three- to 5-year-olds judged stories in which there was an intention to teach or not (teaching vs. imitation) for 4 different learning outcomes (successful, partial, failed, and unknown). They also judged 2 stories with embedded instructional intent (e.g.,…

The purpose of this case study was to determine which mathematical instructional strategies met the learning challenges of a primary-age child identified with 22q11DS. This study investigated the processes by which a young child with 22q11DS acquires mathematical concepts within classroom and tutoring settings. It placed emphasis on building…

Every few years in the United States, history teachers go through what some believe is an embarrassing national ritual. A representative group of students sit down to take a standardized U.S. history test, and the results show varied success. Sizable percentages of students score at or below a "basic" understanding of the country's history.…

From an information processing perspective, humans have a limited attentional capacity for processing information. Thus, second language (L2) researchers have investigated the role of pretask planning in task performance, finding that planning results in greater fluency and complexity but has mixed effects on accuracy. However, most planning…

Contemporary debates on effective pedagogies for K-12 mathematics have called for shifts in the way teachers and teacher educators conceptualise mathematics as a subject and how it should be taught. This is reflected by changes in the curriculum including the inclusion of a strand called Working Mathematically within K-12 mathematics curriculum…

Our research objective focused on monitoring students' mental effort and cognitive achievement to unveil potential effects of an instructional change in an out-of-school laboratory offering gene technology modules. Altogether, 231 students (12th graders) attended our day-long hands-on module. Within a quasi-experimental design, a treatment group…

It is important for children to develop knowledge of words' meanings from a young age because vocabulary development has an impact on their reading comprehension and academic success as they get older. Some children come to school knowing far fewer words than others. Hart and Risley studied young children's vocabulary development and found that…

Using a student's native language, either as a medium of instruction or as a scaffolding technique, has been used effectively in many classrooms throughout the U.S. In the past, many schools provided native language instruction to meet the needs of English Language Learners (ELLs). However, with the advent of antibilingual education proposals such…

Now in a second edition, the award-winning "The Trouble with Maths" offers important insights into the often confusing world of numeracy. By looking at learning difficulties in maths from several perspectives, including the language of mathematics, thinking styles and the demands of individual topics, this book offers a complete overview of the…

Previous studies have demonstrated the efficacy of the Text Structure Strategy for improving text recall. The strategy emphasizes the identification of text structure for encoding and recalling information. Traditionally, the efficacy of this strategy has been measured through free recall. The present study examined whether recall and eye-movement…

This paper aims to contribute to the discussion on the quality and accessibility of underpinning knowledge in competency-based training. It uses the Vocational Graduate Certificate and the Vocational Graduate Diploma in Education Design in a Queensland TAFE [technical and further education] institute to examine how the "traditional"…
