This paper identifies a feature of human brain neural nets that may be described as the principle of ease of processing (PEP), and that, it is argued, is the primary force guiding a learner towards a target grammar. It is suggested that the same principle lies at the heart of Optimality Theory, which characterizes the course of language…

This study was designed to investigate the effects of a dynamic instructional environment, English proficiency, and visualization level, independently and interactively, on middle school students' construction of the concepts of reflection and rotation. The effects of a dynamic instructional environment and English proficiency on students' two-…

The primary purpose of this study was to understand what happens when some aspects of the constructivist approach, namely prediction, explanation, student-centered, and teacher-centered discussions, are applied to science teaching. The study involved 363 junior high school students in Taiwan. It combined the effectiveness of four alternative…

This paper examines the notion of whether computers can provide teachers with the necessary tools to alter the constraints of the traditional classroom and allow for constructivism and independent learning. The study was carried out at Methodist Ladies' College, a girls' school in Melbourne, Australia; information was collected through teacher…

A study identified four principles, based on transfer of learning research and cognitive theory, for guiding curricular decisions, instructional development, and teaching practices in ways that support transferable learning. The principles were as follows: (1) emphasize intermediate-level knowledge in curricular decisions; (2) create in the…

This activity guide for grades K-12 reinforces the concepts of recycling, reducing, and reusing through a series of youth-oriented activities. The guide incorporates a video-based activity, multiple session classroom activities, and activities requiring group participation and student conducted research. Constructivist learning theory was…

It is argued that the debate between qualitative and quantitative research for educational researchers is actually an argument between constructivism and positivism. Positivism has been the basis for most quantitative research in education. Two different things are actually meant when constructivism is discussed (constructivism and…

The purpose of this study is to analyze the perceived thought processes of several students as they learn, and then attempt to solve problems about chemical equilibrium. Four tenth grade students in Taipei, Taiwan, were audiotaped as they individually attempted to solve problems. The problems were such that they required more than mere recall or…

In the West, science is assumed to be an integral part of Western culture. What interests Western educators and policy makers is achievement in science, particularly the comparative achievement in science among students of different Western nations plus Japan. Americans are constantly asking whether or not our students know as much science as…

In the past decade, research on students' ideas has drawn attention to underestimated problems of learning physics. This also particularly applies to Science/Technology/Society teaching. Proposed solutions are mainly inspired by a constructivist cognitive science perspective and are formulated as general teaching strategies that aim at a process…

This paper focuses on reflection and reflective thinking as a means of developing expertise in instructional designers. The need for the reflective instructional designer is discussed, and reflective thinking is examined from several perspectives, i.e., controlled thinking, tacit knowledge, epistemic assumption, abductive reasoning, willingness to…

This study involves action research to explore the effectiveness of the Predict-Observe-Explain (POE) technique in diagnosing students' understanding of science and identifying their levels of achievement. A multidimensional interpretive framework is used to interpret students' understanding of science. The research methodology incorporated…

Followup sessions were conducted for Alabama teachers who completed training in the "Exploring Space: The Classroom Connection" science teaching program in summer 1997. The effectiveness of these sessions was evaluated for 71 teachers. This analysis also allowed for a comparison of several basic concepts about science of the 1996 Alabama…

Eighteen high school science students were involved in a study to determine what attributes in the problem statement they need when representing a typical osmosis problem. In order to realize this goal students were asked to solve problems aloud and to explain their answers. Included as a part of the results are the attributes that the students…

The purpose of this study is to review the changes that computers have on mathematics itself and on mathematics curriculum. The study aims at investigating different applications of computers in education in general, and mathematics education in particular and their applications on mathematics curriculum and on teaching and learning of…
