This aptitude-treatment interaction (ATI) study was designed to clarify the relationship between the aptitude variable spatial visualization and two modes of presentation of linear absolute-value inequalities. The modes of presentation include computer-enhanced instruction (CEI) and traditional. (Author/KR)

Reported is whether and how mathematics has changed during the 75 years of the Mathematical Association of America's (MAA) existence. The progress of mathematics is organized into 9 concepts, 2 explosions, and 11 developments. (KR)

Provides a program listing in True BASIC which constructs several kinds of matrices: (1) matrices with integral entries that have inverses that have integral entries; (2) matrices with integral entries that have inverses that are rational numbers with reasonable denominators; and (3) matrices with integral entries and prescribed integer…

Described are experiences for incorporating writing assignments in mathematics and computer science courses. Reports survey results from students who participated in the courses. (YP)

Outlines an articulation program between college and industry. Describes three seminar courses using the college's computer system. Considers the benefits of the program. (Author/YP)

Presents an example using a computer to illustrate concepts graphically in an introductory course on differential equations. Discusses the algorithms of the computer program displaying the solutions to an equation and the inclination field of the equation. (YP)

A FORTRAN program is provided for use with computer projects for a course in number theory. Uses diminishing functions and the speed of the computer to quickly determine possible solutions to problems. (MVL)

Studies whether students' stated preferences for flowcharts or pseudocodes match their actual behaviors. Provides a review of the literature on flowchart utility. Reports that students preferred flowcharts to pseudocodes. Lists an example of both a flowchart and pseudocode. (MVL)

Describes mathematical problems which occur when using the computer as a calculator. Considers errors in BASIC calculation and the order of mathematical operations. Identifies errors in spreadsheet and calculator programs. Comments on sorting programs and provides a source for Mathemagical Black Holes. (MVL)

Discussion of teaching college level mathematics using computer algebra systems (CAS) focuses on a new microcomputer-based teaching/learning environment called Computer Algebra and Logo (CAL). Highlights include the teachers' role in the development of mathematics teaching and learning environments; methods and goals of implementation; and…

Domino games are used to illustrate problem-solving techniques in a college principles-of-mathematics course. Students develop tables and use Pascal's triangle to find the total number of pips and the sum of numbers on the pieces. (DC)

A Queensland University (Australia) action research project to help foreign students develop skills in the language of mathematics and adjust to the university environment is described. Student, teacher, and observer diary entries indicate students became aware of their language and cultural adjustment needs and made some progress in this…

Reviews the general principles of the reforms addressed by the National Council of Teachers of Mathematics' Curriculum and Evaluation Standards and applies them to community college mathematics. Suggests that challenges to reforming mathematics curricula come primarily from teacher preparation and instruction methodologies and from student-related…

P-adic or g-adic sets are sets of elements formed by linear combinations of powers of p, a prime number, or g, a counting number, where the coefficients are whole numbers less than p or g. Discusses exercises illustrating basic numerical operations for p-adic and g-adic sets. Provides BASIC computer programs to verify the solutions. (MDH)

This article traces the history of zero and its dual role as a placeholder, albeit of empty space, and as a number for computational purposes. The use of one symbol for both situations is shown to be tied to the adoption, and subsequent promulgation, of our modern numbering system. (JJK)
