After spending most of the day in school, students are given additional assignments to be completed at home. It is worth asking not only whether there are good reasons to support the nearly universal practice of assigning homework, but why it is so often taken for granted--even by vast numbers of teachers and parents who are troubled by its impact…

"Evaluating subtest "g" saturation levels via the single trait-correlated uniqueness (STCU) SEM approach: Evidence in favor of crystallized subtests as the best indicators of "g"." "Intelligence," 34, 29-46.] used a single-trait correlated uniqueness (STCU) CFA approach to…

We present a simple laboratory activity for introductory-level physics students which involves rolling balls down pipes and analysing their subsequent flight trajectories. Using balls of equal size but different mass allows students to confront their misconceptions of a mass dependence of the exit speed of the balls from the pipes. The concepts of…

Recently, "Developmental Psychology" published 2 articles on the shape bias; both rejected the authors' previous proposals about the role of attentional learning in the development of a shape bias in object name learning. A. Cimpian and E. Markman (2005; see record EJ733667) did so by arguing that the shape bias does not exist but is an…

Teachers who attempt to promote metacognitive learning strategies in their pupils usually encounter resistance because the pupils believe that they should be instructed by a teacher. One step in overcoming such resistance is to help students to recognize and discuss their implicit views. This document describes a repertory grid which can be used…

The purpose of this study was to investigate senior high school students' difficulties predicting the existence of hydrogen bridge bonds between organic molecules, investigate students' difficulties predicting the relative boiling points of simple organic compounds, and develop test questions that enable teachers to quickly get information about…

To examine the effects of students reading multiple documents on their perceptions of a historical event, in this case the "discovery" of America by Christopher Columbus, 85 high school freshmen read 3 of 4 different texts (or sets of texts) dealing with Columbus. One text was an encyclopedia article, one a set of articles from…

The existence of probability misconceptions at all levels has been well documented. Furthermore, these misconceptions have been shown to be widespread and highly resistant to change. Previous research has shown considerable success in overcoming misconceptions in the short term by basing the knowledge reconstruction process on problems which draw…

A study investigated the relationships among prior topic knowledge, information in elementary science text, and the construction of visual representation of key text ideas. Eight preservice elementary teachers were first interviewed on two topics in science ("how plants get their food" and "air and weather"); then they read…

Many educators in facilitative roles have approached the subject of visual disabilities by constructing activities designed to simulate blindness, using a blindfold or similar device. Participants are subsequently encouraged to perform rudimentary tasks such as eating a meal or moving about with a sighted companion as a guide. Frequently,…

The nature of qualitative understanding and associated learning processes in the context of a computer simulation called the "Envisioning Machine" (EM) are investigated. The questions focused on in this paper include the following: What sorts of knowledge do students' construct? What role does prior knowledge play in the construction of…

In this article, the author compares the arguments of Susan Swartzlander, Diana Pace, and Virginia Lee Stamler (1993) who note the contradiction between the "shockingly unprofessional" practice of asking students to write about their personal traumas in writing courses and the common occurrence of such assignments with Jeffrey Berman…

The Rule Space Model, a cognitive error diagnostic methodology, is discussed, and the philosophy behind it is related to the question of what really determines item response curves. The Rule Space approach integrates Item Response Theory and the algebraic theory of databases. An application of Graph Theory is introduced as a way to acquire a list…

Contemporary researchers often refer to the information processing paradigm to exlain the relative ineffectiveness of contemporary instructional techniques for modifying incorrect scientific concepts that students often bring to a learning situation. As a result of this research, instructional procedures have been developed that maximize the…

Examines the nature of selected traditional cosmological concepts among literate and nonliterate Nigerians. Findings indicate that the respondents, regardless of their status, hold both scientific and traditional notions of the universe. A preference for a scientific world view was evidenced by those who experienced a history/philosophy of science…
