Automated theorem proving (ATP) for Propositional Classical Logic is an algorithm to check the validity of a formula. It is a very well-known problem which is decidable but co-NP-complete. There are many algorithms for this problem. In this paper, an educationally oriented implementation of Semantic Tableaux method is described. The program has…

Focuses on how to write clear programs with C++ that are easier to debug and modify. Student programs designed according to these outlined principles will tend to develop more quickly, have less bugs, and be much easier to debug. (ASK)

Describes a way of incorporating animations into spreadsheets using Excel software. (WRM)

Describes how to modify old QBASIC programs to run in visual Basic. (NB)

Description of a technique in Maple programming language that automatically prints all paths of any desired length along with the name of each vertex, proceeding in order from the beginning vertex to the ending vertex for a given graph. (Author/MM)

Explains how the Roamer Turtle, a piece of technology utilizing the LOGO programming language, can be used in a mathematics curriculum with students aged 4-7. Describes experiences in visiting various classes to see the Roamer in use. (MM)

Demonstrates a less utilized feature of the TI-92+: its natural and powerful programming language. Shows how to implement several linear algebra related algorithms including the Gram-Schmidt process, Least Squares Approximations, Wronskians, Cholesky Decompositions, and Generalized Linear Least Square Approximations with QR Decompositions.…

Discusses the place of linear programming in college curricula and the advantages of using linear-programming software. Lists important characteristics of computer software used in linear programming for more effective teaching and learning. (ASK)

Explores the relative strengths and weaknesses of the spreadsheet approach versus specialized mathematical programming software for solving a particular logic puzzle. (KHR)

Shows how some of the simple ideas in complexity can be investigated using a spreadsheet and a macro written in Visual Basic. Shows how the sandpile model of Bak, Chao, and Wiesenfeld can be simulated and animated. The model produces results that cannot easily be predicted from its properties. (Author/MM)

Covers research conducted within the past 10 years on the topic of using computer models and simulations to aid science instruction at the precollege level. The research is categorized into three main areas: (1) students running preprogrammed simulations; (2) students creating dynamic models using modeling environments; and (3) students using…

Discusses the Texas Instruments calculator the TI-92 and how it can be an effective tool in the mathematics classroom. Provides examples of combining the algebra capabilities of the calculator and Cabri-Geometry II with graphing, tables of values, statistics, programming, and a simple text editor to enhance mathematics instruction. (DDR)

Discusses the reasons for careful evaluation of students' programs by a skilled programmer. Suggests that grades for programs must be partly based on quality factors such as clarity, organization, conciseness, and maintainability. (ASK)

This paper describes how the TI-92+ calculator can be valuable in illustrating basic and advanced programming concepts in introductory computer science courses. Descriptions of the scope of the curricula for the courses in which the TI-92+ is used are provided. The TI-92+ programming language is particularly useful in demonstrating the progression…
