Background: Nanotechnology, a multidisciplinary field with increasing societal importance, demands for an increase in research abilities and capacities. Yet, nanoscience and nanotechnology (NST) are largely inaccessible to K-12 students. This situation demands efforts in research towards bringing NST learning into K-12 classrooms. Purpose: The…

We describe here lessons learned in designing an early algebra curriculum to measure early algebra's impact on children's algebra readiness for middle grades. The curriculum was developed to supplement regular mathematics instruction in Grades K-5. Lessons learned centered around the importance of several key factors, including using conceptual…

The notion of learner autonomy has attracted the close attention of scholars, teachers, policy makers and researchers in various countries. In Indonesia, while its scope remains limited, learner independence is one of the highlights of the current curriculum. The purpose of this study was threefold: to investigate how Indonesian secondary school…

In education, terms and concepts are extremely important in terms of description of a variety of facts and events. Concepts are considered the building stones of knowledge. Concepts are important in teaching Social Studies that aims to provide the basic citizenship skills, and in teaching the subjects contained within the Social Studies course.…

Writing readiness is based on linguistic readiness, conceptual readiness, and a knowledge of the composition process. (DD)

Describes a study which used fourth and sixth grade children who had used Science - A Process Approach" and compared their performance with that of a control group on two conservation-of-volume tasks. Performance of the volume tasks was found to be related to age and score on the Learning Hierarchies Test and not to previous science program…

Considers the philosophy underlying learning and needs in adult education. (RK)

Research was done to investigate the interfunctional relationships between a child's ability to order a set of objects and the development of language descriptives used to describe differing aspects of a group of objects which had been ordered. Results show that mean age of concrete operation acquisition is 7.1 years. (Author/JB)

Empirical data relate to Bruner's and Ausubel's theories of learning concepts at different age levels. The concept of vector addition was taught to eighth, ninth, and tenth grade students. The concept was learned and retained by high ability ninth and all tenth grade students. (PS)

Discussed are the problems of teaching and learning fractions in the upper primary and lower secondary schools. Recommendations for teaching fractions are made and defects in various methods of fraction instruction are identified. It is suggested that fractions not be taught in upper primary and lower secondary schools. (Author/DS)

This paper provides for the elementary school teacher an introduction to the problem of mathematics readiness. The first part outlines the four developmental stages as seen by Piaget, and the manner in which schemata develop through the process of assimilation and accommodation. The second part consists of seven Piagetian tasks which a teacher may…

Three aspects of concept teaching might be guided by the conceptual learning and development model. First, by assessing the characteristics of cognitive style, classificatory skills, and logical reasoning ability, the student's readiness to attain concepts under various circumstances can be determined. Secondly, the model points to optimal methods…

Explores how students' epistemological ideas about the nature of science interact with their conceptual understanding of a particular domain as reflected in written explanations for an event of natural selection constructed by groups of high school students through a technology-supported curriculum on evolution. Highlights the need for an…
