Examines the development of children's understanding of the difference between "want" and "need" in two different experiments. The first experiment required the children to respond verbally in choosing between the two concepts; the second required them to give an object to one of two characters who had made a request using…

Extends William James' classification of phenomenalistic reality (PR) and analyzes PR using empirical data available in developmental psychology; focuses on the relation of PR to a human subject; to rational constructions; and to the idea of truth. Concludes that the development of phenomenalistic reality is qualitatively different from the…

Explores how inscriptions are used to create argumentative positions in two classroom episodes. Finds that the classroom activities resembled those of scientific communities in several ways: (1) Real-world, dilemma-driven problems were presented; (2) students evaluated the inscriptions offered in terms of their adequacy for advancing particular…

Uses four children's explanations to illustrate their use of assimilation and inference in a butterfly life-cycle activity. Describes how interviewing young children about their understanding, and recording and reflecting upon their answers, can allow teachers to better understand how students process information and construct knowledge, and…

Focuses on how conceptual themes can assist students in problem solving by acting as organizing elements and guides for thinking. States that students can learn how to use important ideas to drive key questions, discern the relationships among concepts that reflect the operation of principles, and visualize a problem to clarify essential issues.…

Focuses on problem-based curriculum students' generation of learning issues that are guidelines for their individual study. Investigates how many learning issues can be classified as being of good quality and presents examples of well and poorly formulated ones. (DDR)

This paper is about a longitudinal study to investigate how student-teachers developed understanding of some key ecological concepts during a teacher education programme. Another aim was to interpret the student-teachers' intentions in respect of the programme and to examine how these intentions influenced their learning. A group of students were…

Although research from a developmental/psychological perspective indicates that many children do not have a scientific understanding of living things, even by the age of 10 years, little research has been conducted about how students learn this science topic in the classroom. This exploratory research used a case-study design and qualitative…

Fourth-grade students who participated in a yearlong, whole-class teaching experiment not only reconceptualized natural numbers but also generated flexible solution strategies to perform numerical computations mentally and in writing. Students' reconceptualization of number was mediated by their perceived resemblance between the physical action of…

This article describes a unit of instruction designed to promote a conceptual understanding of area in sixth-grade students. Students used benchmarks to estimate the areas of real houses and calculated the areas of houses based on building plans. (Contains 7 figures.)

This study investigates the potential of enhancing students' learning of difficult science concepts by exploring the interaction between teachers' four different instructional approaches and students' four different learning preference styles. Students' immediate performance and their retention for learning of buoyancy concepts serve to examine…

This research study was conducted in Trinidad and Tobago to investigate students' responses to a summative assessment of a cross-cultural unit of work.

This paper examines Oxford University students' conceptions of the role of the tutorial in their learning. An analysis of interviews with 28 students constituted four qualitatively different conceptions of the "Oxford Tutorial". These ranged from the tutorial involving the tutor explaining to the student what the student did not know, to the…

"The Alex Studies: Cognitive and Communicative Abilities of Grey Parrots" by Irene Pepperberg is reviewed from a behavior analytic orientation. The results of the majority of her experiments are discussed in terms drawn from the general literature of behavior analysis and Skinner's analysis of verbal behavior. We conclude that she has provided…
