Cross-sectional and incremental age effects on cognitive processes that underlie individual differences in components of working memory (WM; phonological loop, visual-spatial sketchpad, executive processing) and mathematical problem-solving accuracy were examined in elementary school children. A battery of tests was administered that assessed…

This article describes an integrated activity that can teach students important lessons in recycling, manufacturing, measurement, art, and ecology, while at the same time putting old crayons to good use. The activity involved organizing fourth-grade students into a manufacturing company that would melt old crayons into molds to form a new product…

This paper, written in the twenty-first anniversary year of the journal "Educational Psychology in Practice", attempts to uncover those distinctive aspects of the discipline and the practice of applied psychology in general and educational psychology in particular. After considering some of the reasons for attempting this task at this point in…

This article explores the concept of the "vocational" in contemporary educational discourses, and argues for the centrality of vocational aspects of learning in making meaning. The existing tensions are seen to lie between discourses that place the vocational at the bottom of a hierarchy of knowledge and value, and discourses concerning…

This paper investigates the learning behaviour, learning environment and learning outcomes of Hong Kong Chinese students enrolled on an Australian university's Bachelor of Business degree course taught by visiting Australian lecturers in Hong Kong. The Chinese students are task-focused and passive learners. They do not demonstrate creative…

This note discusses the boundary in the frequency--amplitude plane for boundedness of solutions to the forced spring Duffing type equation. For fixed initial conditions and fixed parameter [epsilon] results are reported of a systematic numerical investigation on the global stability of solutions to the initial value problem as the parameters F and…

In this article, the authors share the case of John, a college freshman who had been struggling with depression. To work around John's case, the authors conducted an interview with John's parents. Based on the interview, it is found out that John's depression was largely caused by his relationship with his parents and the environment at their…

Trends in animal production have moved the industry toward large confined animal feeding operations (CAFOs). These CAFOs concentrate large amounts of manure-based nutrients in relatively small areas, which increases the risk of nutrient loss to the surrounding environment. In response to water quality concerns, P-based manure application…

In the fall of 2003, the author conducted research on the student teaching process in Japan. The basis for most of the lessons observed was rich mathematics problems. Upon returning to the US, the author used one such problem while teaching an algebra 2 class. This article introduces that problem, which gives rise to both linear and quadratic…

Relationships become so close in early childhood programs that many parents describe early childhood staff as their children's "extended family." And yet, no matter how genuine attachments are, there still remains the fact that parents are, in fact, the school's paying customers. When money is exchanged in the U.S., the typical rule of thumb for…

Interest in foreign-language instruction in preschool is growing, both among parents and early-childhood educators trying to meet the demand. The interest, though, comes at a time when some districts are scaling back on such programs in the elementary grades in order to spend more time on reading and mathematics--the subjects currently tested to…

This article describes an interdisciplinary course that develops essential mathematical modeling skills within an introductory biology setting. The course embodies recent recommendations regarding the need for interdisciplinary, inquiry-based mathematical preparation of undergraduates in the biological sciences. Evaluation indicates that the…

A problem sometimes called Moser's circle problem where a circular region has to be partitioned with chords without any three chords intersecting at one point, is discussed. It is shown that Moser's circle problem makes the students to use a variety of mathematical tools to find correct solutions to problems and gives an opportunity to think about…

Many students find it difficult to learn the kinds of knowledge and thinking required by college or high school courses in mathematics, science, or other complex domains. Thus they often emerge with significant misconceptions, fragmented knowledge, and inadequate problem-solving skills. Most instructors or textbook authors approach their teaching…

The No Child Left Behind (NCLB) Act of 2001 requires states to ensure that all students make adequate yearly progress in achieving proficiency in English language arts and math. This study examines how six diverse schools have responded to the challenge of educating their students in math, particularly students with disabilities and other…
