The aim of this research is to advance in the teaching-learning process of representing quadratic functions, both with pencil and paper and with a technological tool. For this purpose, a didactic experience is presented. Firstly, it is explained in the traditional way how to graph a quadratic function; secondly, students are introduced to the…

The purpose of this case study was to examine prospective mathematics teachers' lessons in the context of choice and use of representations while teaching limit. The participants were four senior prospective mathematics teachers. The data were obtained from the participants' lessons plans, the video recordings of their lessons, and the…

"Science and Engineering Indicators" ("Indicators") is a biennial congressionally mandated report that provides high-quality quantitative information on the U.S. and international science and engineering enterprise. The report employs a variety of presentation styles--such as narrative text, data tables and figures--to make the…

Introduction: This article reports on a study that explored the benefits and drawbacks of using spatially positioned synthesized speech in auditory interfaces for computer users who are visually impaired (that is, are blind or have low vision). The study was a practical application of such systems--an enhanced word processing application compared…

It is a pity that for so many people not involved in Teaching, and for a surprising number who are, mathematics in schools is "chiefly" all about the ability to know a set of facts, multiplication tables and addition bonds in particular, rather than the capacity to reason and explore patterns and relationships in Number and Shape.…

The ability to visualize student engagement and experience data provides valuable opportunities for learning support and curriculum design. With the rise of the use of learning analytics to provide "actionable intelligence" on students' learning, the challenge is to create visualizations of the data, which are clear and useful to the…

(13…

This second in a series of articles on a software evaluation project conducted by the Netherlands Association of Users of Online Information Systems (VOGIN) lists and compares specifications, properties, and test results for nine microcomputer-based software programs that fall into the category of classical information retrieval systems. (26…

Lists and compares specifications, properties, and test results of eight microcomputer software programs for information storage and retrieval by endusers. This is one of a series of articles that have reported the results of a software evaluation project conducted by The Netherlands Association of Users of Online Information Systems (VOGIN). (22…

Describes an empirical study of students in a Swiss secondary school that was conducted to investigate whether courseware and student characteristics have an impact on learning achievement. Factors to be considered in the design and evaluation of courseware are discussed, students' computer attitudes are considered, and recommendations for further…

Describes study that investigated teachers' criteria for the use of courseware packages in Dutch junior high school physics classes. The development of a courseware evaluation instrument is described; drill and practice, simulation, and tutorial courseware packages are evaluated; motivating elements are considered; and implications for the design…

This paper presents the outcome of research that deals with the development and use of World Wide Web hypermedia courseware in student teachers' education in the Department of Information Science at the Faculty of Philosophy, University of Rijeka (Croatia). The purpose of this research is to explore how the use of Web courseware improves the…

Presents 1992 sales of microcomputer systems by vendor. Customer support services, a new interchange format for MARC records, vendor market share and other statistics, foreign sales, and large and small systems are discussed. Profiles of 14 vendors, a chart of compatible system interfaces by vendor, and a directory of microcomputers sources are…

Describes an evaluation of educational software that compared software produced in Taiwan with software produced in the United States. Results showed a surprisingly small number of cultural differences other than language; article suggests that multimedia guidelines for international audiences would be helpful. (LRW)

Microcomputer installation in schools has increased annually since 1983, and microcomputers are now utilized throughout Japan's educational system, both in elementary and secondary classrooms and for educational research. Most of the computer software used in computer-assisted instruction is acquired externally, as opposed to developing the…
