An important priority of educators is to modify the school structure so that "at-risk" learners can be treated as all other students are treated. One way of sending a positive message to all students is to organize classrooms heterogeneously. Intra-class grouping is a source of help when it emphasizes cooperation among learners and…

The Iowa Test of Educational Development (ITED), a test of general abilities given to high school students, is intended as a tool for teachers and administrators to measure the progress of their students and plan accordingly; it also purports to assess the use by students of critical and evaluative abilities. Because such tests as the ITED carry…

A review of the literature reveals that obstacles to the successful transfer of basic skills, knowledge, and thinking skills during classroom instructional time differ depending on which of three components of expertise is entailed: conceptual understanding, domain-specific basic skills, or domain-specific strategies. This article, accordingly,…

This paper points out that one of the most appropriate and needed areas in which students should engage in critical thinking is in their everyday responses to messages aimed at them in attempts to persuade and convince them to buy or believe something. Ten commonly used tactics noted in the media are described. Examples are given of slanted or…

This document describes the implementation of a practicum intervention designed to improve the analytic abilities of academically above-average fifth and sixth graders in a class that emphasized academic excellence. When students were tested on the development of complex thinking abilities, several areas needing improvement were identified. A…

Designed to assist technical assistance center staff members and other inservice providers, this workshop leader's guide contains step-by-step procedures for preparing, organizing, and presenting a one-hour workshop on advanced skills for teachers, administrators, and others associated with Chapter 1 programs. Sections of the guide include: (1) an…

This study investigated how people reason about simple mechanical devices and physical systems, and how reasoning methods and understanding of a device evolve over a period of exposure. Twelve students attending the Teachers College at Columbia University (New York) participated in the first of two experiments; and 10 students attending the same…

The objectives of this study guide are: (1) to increase student understanding of the prevalence of youth participation in violent conflict and the challenges to addressing this global issue; (2) to familiarize students with strategies for conflict prevention, management, and resolution; (3) to develop students' analytical reading, writing, and…

In its empirical part this paper establishes a general weak understanding of the process of applying a mathematical model. This is also evident in the way teachers regard the application of alternative sharing in their own problem solving and in relating to children's answers. The theoretical part analyses problems that are considered as…

This book is designed to help adults gain the range of math skills they need to succeed in life and work and on standardized tests, including the GED. It is expected to help students overcome math anxiety, discover math as interesting and purposeful, and develop good number sense. Lessons are organized around four strands: (1) skill lessons that…

The major idea in this paper is the formulation of a theory of three distinct but interrelated worlds of mathematical thinking each with its own sequence of development of sophistication, and its own sequence of developing warrants for truth, that in total spans the range of growth from the mathematics of new-born babies to the mathematics of…

This paper uses data from two mathematics lessons to explore the nature of progressive discourse and examine critical features of teacher actions that contribute to mathematics classrooms functioning as communities of inquiry. Features found to promote progressive discourse include a focus on the conceptual elements of the curriculum and the use…

In productive classrooms, teachers do not just teach children skills: they build emotionally and relationally healthy learning communities. Teachers create intellectual environments that produce not only technically competent students, but also caring, secure, actively literate human beings. Choice Words shows how teachers accomplish this using…

To provide a better understanding of the structure of the Medical College Admission Test (MCAT) and to determine if there are structural differences across selected groups of MCAT examinees, several dimensionality analyses were conducted on data from recent administrations of the MCAT. The first set of analyses focused on the global structure of…

This paper describes how one group of students developed personally meaningful ways to reason mathematically within the context of measurement. Episodes taken from a first grade classroom in which a 4-month teaching experiment was conducted are presented. One of the goals of the teaching experiment was to develop instructional sequences designed…
