This paper will provide several examples of science and mathematics integration: navigation/map-reading, ecology/ecosystems/population growth, and chemistry/molecular structures. This paper underscores integrating STEM subjects with problem-based learning with technology such as video/computer simulations/programming/coding and the dynamic free…

Describes the use of computer graphics simulations to enhance student understanding of sampling distributions that arise in introductory statistics. Highlights include the distribution of sample proportions, the distribution of the difference of sample means, the distribution of the difference of sample proportions, and the distribution of sample…

Discusses the use of educational technology for science and math instruction in elementary and secondary schools through conversations with six curriculum specialists and administrators. Highlights include the use of IBM and Macintosh hardware and software; hand-held computers; integrated learning systems; math workstations; computer simulations;…

The analysis and simulation of spiral growth in plants integrates algebra and trigonometry in a botanical setting. When the ideas presented here are used in a mathematics classroom/computer lab, students can better understand how basic assumptions about plant growth lead to the golden ratio and how the use of circular functions leads to accurate…

Reacts to Ohlsson, Ernst, and Rees' paper by initially discussing the costs of methodology that utilizes artificial intelligence (AI) to model cognitive processes. Raises three concerns with the paper: insufficient clarification of the meaning of conceptual versus procedural understanding of base-10 subtraction; realism of the learning model; and…

Responds individually to Shoenfeld's objections that Ohlsson, Ernst, and Rees' model is unclear; that the hypotheses about learning are unjustified; that the models have not been tested against extant data; and that it is unclear whom the model models. (MDH)

Discussion of the use of new technologies in science instruction focuses on the medium of CD ROM. Topics discussed include database retrieval; simulations and laboratory experiments; videodisks; hypertext; and software and interfaces for laboratory experiments. A list of math and science resources is provided. (LRW)

This first of two articles presents eight examples of what software infusion (SI) looks like in actual practice in elementary, middle, and high school classrooms and learning laboratories. An analysis of SI characteristics demonstrated in the examples is presented to bring the definition of SI into focus. (MBR)
