Inequalities are considered among the most useful tools of investigation in pure and applied mathematics; yet their didactical aspects have not received much attention in mathematics education research until recently. An important aspect of teaching problem solving at the secondary level deals with the notion of equivalence of algebraic…

This paper focuses on challenges in mentoring software development projects in the high school and analyzes difficulties encountered by Computer Science teachers in the mentoring process according to Shulman's Teacher Knowledge Base Model. The main difficulties that emerged from the data analysis belong to the following knowledge sources of…

Describes a database courseware using the HyperCard program on the subject of human reproductive endocrinology and feedback mechanisms. Discusses some issues concerning database courseware development. Presents several examples of the courseware display. (Author/YP)

This paper was developed with the goal of enhancing the mathematical preparation of secondary school teachers in the technological paradigm. It shows how two-variable inequalities can be utilized as models for the construction of geometric objects using the software Graphing Calculator 3.5 (produced by Pacific Tech) as a relation grapher. An…

Examines the use of a computer simulation program as a tool to help in the understanding of wave phenomena. After analyzing some of the main difficulties and common misconceptions about waves, features of the "Making Waves" software package are described. Figures showing a typical monitor display are presented. (YP)

The No Child Left Behind Act of 2001 (NCLB) effectively shifted the K-12 educational paradigm to a system that places a high premium on performance and accountability. The impact of the NCLB legislation and the adoption of the Nevada High School Mathematics Proficiency Examination (NHSPEM) have created the need for instructional materials that…

Examines the strengths and weaknesses of five selected statistical software packages with respect to how well the software enhances business statistics instructors's ability to teach traditionally difficult topics. Ranks the software on technical and pedagogical benefits. Results indicate (1) no advantage to using textbook-related software over…

Discusses the nature and uses of LOGO programing language with primary children. Sample program listings and the results obtained by primary children are included. (JN)

Discusses various ways in which computers can be used in marine science studies. Includes representative software which illustrate marine science concepts and goals of the Computerized Marine Education Network. (JN)

Presents a collection of short items, including: (1) a routine to watch while computer processing occurs; (2) a MSBASIC-to-WORDSTAR translator; (3) an easy by-column printout; and (4) a selection of one-line functions, such as automatic string centering. (JN)

Case-study descriptions of secondary and middle school classrooms in diverse contexts provide examples of how teachers implement connected classroom technology to facilitate formative assessment in science instruction. Connected classroom technology refers to a networked system of handheld devices designed for classroom use. Teachers were…

Reviews three software packages: (1) "The Weather Machine Courseware Kit" for grades 7-12; (2) "Exploring Measurement, Time, and Money--Level I," for primary level mathematics; and (3) "Professor DOS with SmartGuide for DOS" providing an extensive tutorial covering DOS 2.1 to 4.0. Discusses the strengths and…

An online homework system created for use by beginning calculus students is described. This system was designed with the specific goal of supporting student engagement outside of class by replicating the attempt-feedback-reattempt sequence of events which often occurs in a teacher's presence. Evidence is presented which indicates that this goal…

Presents a classroom-tested, easy-to-use, multipurpose program (written in Applesoft BASIC) for graphing equations. A complete listing of the program (which is suitable for a wide range of applications in grades 7-12 mathematics classrooms) is included. (JN)

Iteration is the process of doing something repeatedly in a computer program. In LOGO, the most elementary form of iteration is provided by the REPEAT command. This paper explores how programers can use LOGO's extensibility to create more powerful iterative forms than those offered by the REPEAT command. (JN)
