Discusses the benefits of school library security, software security, and computer security systems. Describes specific products for each type of security system. A sidebar lists names and addresses of security manufacturers and distributors. (AEF)

Scenario refers to specific courses of action/events occurring within computer simulations and attempting to recreate lifelike situations. This article identifies critical features and their elements in designing effective scenarios in computer-based instructional simulations: (1) sequence; (2) operating procedures; (3) characteristics of…

Describes how students in a 10th-grade geometry class discovered relationships that led to the development of conjectures, theorems, and directions of proofs regarding the centroid of a triangle. (ASK)

Presents an activity on the sum of the measures of the interior angles of a five-pointed star by using The Geometer's Sketchpad. (ASK)

Discusses six principles of visual perception and their cognitive implications for interactive screen design: clear perception determines continuity and flow of information; perceptual grouping establishes screen sequencing; placement of information aids recall; distinctiveness increases retention and retrieval; consistency in the perception of…

Discusses the application of computer based training (CBT) to human-computer interface design. Describes course considerations; courseware; and software environment for practice, and presents a case study outlining small group production of interactive guidebooks. Concludes that CBT can reduce instructional time and is an effective method for…

Argues that there is a need for more research on the effectiveness of instructional methods in developmental education, but acknowledges that standard experimental procedures are not appropriate for developmental classrooms. Describes Simulation Implementations of Peripatetic Learning Environments (SIMPLE), a computer-based tool for creating…

Steps in preparing effective overhead projector transparencies for college instruction are outlined, using the PowerPoint program for Windows. They include thinking analogically in translating from concept to visual form; using the features of the presentation program to create a polished product; and assuring readability (visibility, typeface…

Proposes activities that promote students' awareness of the structure of the information involved in their everyday activities, and builds the concept of function from students' mental representations of phenomena. Recommends the use of spreadsheets to provide external representations of these functions. (DDR)

Describes the Computer-Assisted Personalized Assignment (CAPA) system which offers a way to apply computers to assist instructors and students in the framework of lectures and assigned problem sets without students being forced to use the computer system. (DDR)

Provides the results of a survey of science teachers (n=635) regarding the status of computer use and professional development needs related to the use of computers in classrooms. Results indicate that 91% of the classrooms have computers. Professional development needs are categorized by groups: non/past users, novices, and users/experts. (DDR)

Provides an overview of the 1995 EUROCALL conference and gives short descriptions of some of the papers presented. (CK)

Considers the use of technology, particularly programmable or graphics calculators and computer software, in the transition years from secondary to higher education. Discusses use of software systems like Mathematica in the extended investigative, problem solving, and modeling Common Assessment Tasks of the Victorian Certificate of Education.…

Describes how a software package that includes a spreadsheet, a relation grapher, and a dynamic geometry can contribute to teacher training through an exploratory problem-solving course. Discusses the ways in which technology-rich environments enhance and extend traditional topics. Contains 17 references. (DDR)

Describes a preliminary test on graduate students of a software tool designed to perform computations required in event sequence analysis, that will enable researchers to measure and empirically test student interactions and critical thinking in threaded discussions. Explains the Discussion Analysis Tool (DAT) and suggests implications for…
