We explored how preservice teachers in a middle school science methods course learned and applied computational thinking (CT) concepts and activities during a month-long intervention. In the intervention, preservice teachers learned about CT concepts through an hour-long lecture in their methods class, practiced a computing-integration activity…

In this paper, we report on our efforts to support teachers' development of mathematical knowledge for teaching through online professional development focusing on authentic engagement in collaborative mathematical problem solving. In particular, this paper seeks to explore and understand the relationship between online mathematical collaboration…

This study documents problem solving approaches that high school students develop as a result of using systematically Cabri-Geometry software. Results show that the use of the software becomes an important tool for students to construct dynamic representations of the problems that were used to identify and examine different mathematical relations.…

This review investigates the use of certain types of interaction in mathematics education. These types include interaction between students, interaction between teacher and students, and interaction between students and learning technology. Student-technology interactions are explained by computer programs that use problem-solving strategies and…

Describes teaching methods in a computer-based learning environment called WORDMATH, designed to teach word-problem solving to 9-to 12-year-old students in Singapore primary schools. Discusses the results of a formative study of the tutor. (Author/ASK)

Pilots and evaluates a math activity initially utilizing M&Ms as manipulatives, then progressing to computer software math activities, in five early childhood classrooms. Concludes that there were no significant differences between learning tasks, monolingual students vs. bilingual students, and manipulative (hands-off) activities vs. computer…

Examines 16 high school computer textbooks used in Taiwan with an attempt to analyze the nature and the presentation styles of programming examples in them. Concludes that presentation of programming examples in most of the analyzed textbooks lacked a detailed explanation of some of the problem-solving steps. (Contains 26 references.) (Author/ASK)

This paper describes the global feedback in ActiveMath, a Web-based adaptive learning environment for mathematics and beyond. It addresses some of the cognitive foundations and the architecture of the suggestion mechanism with its components. This architecture separates components for diagnosis from components for suggestions and different types…

Presents graphic means of representing deductive proofs in a sentential system of symbolic logic. Provides students with performance data following a description of the rule set and the working backwards method. Shows that one interface design is superior to others in respect to working backwards. Draws some general conclusions concerning the…

Given are instructions for teaching spreadsheet use for problem solving in mathematics. Examples of relevant problems from algebra through calculus are provided. The advantages of using computer spreadsheets in this application are stressed. (CW)

Abstracts of seven selected papers from the 7th Annual Microcomputers in Education Conference are presented. Papers are included on microcomputer-based labs, teaching science with robots, microcomputer software, problem solving, computer integrated math activities, and computer assisted mathematics. (RH)

Discusses the features and advantages of the computer language PROLOG, and explains the approach taken in teaching it as a first computer language. Includes an example of the use of PROLOG in programming a science lesson on elements for junior high students. (ML)

Investigates students' understanding of the basic concepts of introductory set theory which are set, set element, cardinality, subset, and the empty set. Data was collected from preservice elementary school teachers. The project included experimentation with basic set concepts in an open computer-based environment using the mathematical computer…

Describes the approach used in a doctoral seminar on designing instructional software for problem solving in mathematics. Explains how a five stage software development model was followed for producing materials. Includes student evaluations of the course. (ML)

Described is a series of computer tutorials developed to teach students a logical method of problem solving for chemistry. The structure, pedagogy, and problem-solving strategies of the computer software program are described. (CW)
