This book uncovers the important issues in language learning and teaching in the intelligent, digital era. "Social connectivity" is a contemporary style of learning and living. By engaging in the connectivity of physical and digital worlds, how essential parts of language learning and teaching can be achieved? How can the advanced…

Discussion of the use of computers in math instruction highlights two possibilities suggested in response to an earlier journal column: (1) a program written in BASIC for producing spirolaterals, and (2) the use of LOGO list processing to solve matrix problems for exploring geometric transformations. (LRW)

Discusses the effectiveness of using prompting in computer assisted instruction and time delay fading of such prompts to teach new skills to students who have difficulty learning by traditional methods. A CAI tutorial program which uses these techniques to teach time-telling skills is described. (MBR)

Presented are ideas for teaching mathematics with a microcomputer. Ideas include using Apple II Logo to help select students for activities (Wheel of Fortune) and activities to explore how the programming operates. (RH)

Presents a problem and a line of reasoning inspired by working in dynamic geometry environments and allowing students to make a geometric construction on the computer and then manipulate the construction by dragging points, lines, and segments. (MKR)

Exploratory study aimed to investigate elements of geometrical concepts that children learn through Logo programing. A test designed to assess three components of length and angle was administered to 84 children who had learned Logo for one year and 92 who had not. Data indicated a positive effect of Logo work on some items, but not all.…

Shows how a simple spreadsheet program can be used to teach calculus concepts more effectively through simultaneous use of review questions and instructions, actual manipulation of data and formulas, and visual illustration of results. Concepts illustrated include the difference quotient and derivation of a function; difference and differential;…

Describes a method for integrating basic instruction on computer programing in mathematics courses for earth science, chemistry, and pharmaceutical chemistry students to provide them with a knowledge of the real possibilities of computing media. (CHC)

Offers examples of loss of accuracy when using digital computing devices. Discusses causes for loss of accuracy and methods of preventing loss. Presents implications that loss of accuracy has for mathematics instruction. (MDH)

Investigates potential uses for spreadsheets that generate graphical representations, and explores complex sheets that can be used purely as demonstrations, which require far less time and expertise than writing equivalent computer programs. Includes several spreadsheet examples using Microsoft Excel. (JJK)

Student, teacher, and teaching causes of mathematics anxiety are discussed. Computer-assisted instruction can reduce mathematics anxieties due to lack of confidence, negative attitudes, teacher bias, authoritarian teaching, lack of variety, lack of relationship with the real world, emphasis on memorization or on speed, or computer phobia. (MNS)

Presented is an interactive Applesoft BASIC program that graphically demonstrates the central limit theorem. It can be used as the basis of a lab to illustrate the main conclusions of the theorem. (MNS)

Computer-enhanced simulation of models permits students to become subjectively involved in interaction with the computer. A method for developing a computer simulation is described, and three examples of computer simulations are given. (JN)

Use of computer programs as tools for instruction on statistics is presented. A program for TRS-80 Level II BASIC is included. (MP)

General guidelines for a process evaluation of software for a specific subject and grade include: (1) Specify instructional objectives and list desired software program characteristics; (2) Access and review descriptions of programs (information sources for math programs are listed); (3) Preview software; and (4) Compare and make purchase…
