A computer program (written in Applesoft BASIC) to score the Scientific Attitude Inventory (SAI) has been developed. The program takes approximately seven minutes to process a file containing 150 subjects. A complete listing of the program (which is available from the author on diskette) is included. (JN)

A narcissistic number is a positive integer equal to the sum of its digits raised to an integral power. For example, 15 is equal to 1-cubed plus 5-cubed plus 3-cubed (a narcissistic number of order three). A computer program to find narcissistic numbers up to 10,000 is given and discussed. (JN)

Presents a method for using matrix algebra and computers to encode and decode secret messages. Provides examples of coding procedures, a short review of matrix multiplication, and a BASIC program for use with secret messages containing up to 1000 numbers. (RT)

Described is a strategy that allows students to experiment with probability without applying formulas to solve problems. Students are able to intuitively develop concepts of probability before formal definitions and properties. Sample problems are included along with BASIC programs for some of the problems. (KR)

The purpose of this paper is to show, by computer examples, that very different results can be obtained by rearranging selected conditionally convergent series. Computer programs allow the students to select the real number to which they wish the rearrangement to converge. Two computer programs are appended. (KR)

Describes several phenomena in which interesting properties of numbers are demonstrated. Includes discussions of amicable, perfect, and sociable numbers. Presents computer programs for conducting a number chain search. (RT)

Includes a list of favorably reviewed microcomputer software designed to be used in instructing students in kindergarten through grade 12. Developed as an aid to educators in previewing software, the list provides the name, type, cost, publisher, and grade level for instructional software in science and mathematics. (TW)
