Qualitative features of teacher-student interaction during classroom teaching and learning while modern technological thinking and problem-solving skills were mediated were studied for 22 seventh-grade boys in Finland. Reciprocal understanding between teacher and student were necessary in order for the teacher's special instructional assistance to…

Offers practical suggestions for a coherent approach to the teaching of grammar in foreign language classrooms. As a context for the ideas offered, the article synthesizes some of the views expressed by recent writers on this subject. The model outlined provides a basis for work designed to focus more on accurate use of language than on…

Outlines a model for distance collaboration between business writing classrooms using network technology. Discusses ways to teach national and international audience awareness, problem solving, and the contextual nature of cases. Discusses goals for distance collaboration, sample assignments, and the pros and cons of network technologies. (SR)

Presents two methods for solving equations. An asymmetric approach works backward from a number by reversing operations performed on a variable. A symmetric approach views the equation as a scale and performs inverse operations on both sides of the balance to solve for the variable. (MDH)

Discusses the rate of fall of a wooden beam or a chimney by examining the fall of a highway lamp pole when it is sheered off at its base upon impact by a vehicle. Provides the mathematical formulas to explain and an experiment to illustrate the phenomenon. (MDH)

Reviews the history of the concept of function, looks at its relationship with other sciences, and discusses its use in the study of real world situations. Discusses the process of constructing mathematical models of function and emphasizes the importance of the roles of the numerical, graphical, and algebraic representational forms. (MDH)

Presented is the solution to the problem of calculating the probability of winning or losing a game played by moving a counter from the center of a hexagonal grid according to the number shown after the toss of a die. The exercise is an example of an interesting mathematical investigation. (MDH)

Cognitive apprenticeship emphasizes a combination of authentic problem-solving experiences with expert guidance in lieu of decontextualized instruction. This article examines issues in cognitive science and describes a model of cognitive apprenticeship for providing academic instruction to students with special learning needs. (Author/DB)

This article describes "Thinking Actively in a Social Context," a multiphase model to assist in the development of problem-solving courses based on student needs and experiences. An example of such an interdisciplinary course (simulating a new settlement on another planet) for high ability children in grades five, six, and seven is detailed. (DB)

Presents a model that uses online searching to teach critical thinking skills in elementary and secondary education based on Bloom's taxonomy. Three levels of activity are described: analyzing a search statement; defining and clarifying a problem; and focusing an information need. (Contains 13 references.) (LRW)

Explored are the distributions of residual components in two model systems. A system of components with exponentially distributed lifetimes and the two-dimensional "leaf model" in which objects fall on a plane with positions independent and normally distributed are discussed. Included are the definition, application, computations, and theorem. (KR)

Review of research and development on the design of computer-based simulation for diagnostic training highlights the development and evaluation of eight diagnostic training systems that explored the appropriate level of student modeling needed for technology training. Topics addressed include changes in interface design, displays, and system…

This article reports on answers by children (grades 1-9, n=83) to oral and written questions concerning the phase change from liquid to gas. The development of concepts was followed, proceeding from concrete to abstract ideas. Many students were found to experience difficulties in problem solving even though they may have had the necessary level…

The Quality Circle Model of Planning is presented as a program evaluation approach for schools serving students with blindness. The model helps administrators solve problems using creative, innovative approaches; identifies human and monetary resources for successful implementation of the plan; and provides a framework for evaluating the plan's…

The case of a school district refusing to supply an interpreter for an above-average student with a hearing impairment is used as a point of departure for this discussion of a framework for ethical deliberation and the special role-related obligations that help define the ethics of special education.
