Engineering design-based STEM integration is one potential model to help students integrate content and practices from all of the STEM disciplines. In this study, we explored the intersection of two aspects of pre-college STEM education: the integration of the STEM disciplines, and the NGSS practice of engaging in argument from evidence within…

This study explored how mathematics content and methods courses for preservice elementary and middle school teachers could be improved through the integration of a set of instructional materials based on the National Assessment of Educational Progress (NAEP). A set of eight instructional modules was developed and tested. The study involved 7…

The author advocates directed change as constrasted with change for its own sake in the present quest for relevance at all levels of mathematics education. (CP)

Cites examples from medical research, medical ethics and genetic counseling to point for the need of a secondary school course in values clarification in bioethics. (CP)

Discusses the content and structure of the secondary school science program "Time, Space and Matter," and responds to an earlier criticism of the program published in this journal. (JR)

Encourages elementary and secondary school mathematics teachers to foster skill development in approximation, estimation, interpolution and orders of magnitude. (CP)

To meet the need for reform in mathematics teacher preparation courses, two cycles of changes made in an elementary mathematics methods course are presented. Using action research, teaching approaches were developed, implemented, and evaluated as a meaningful way to continue my professional development. Results suggested that I improved my…

Provided is a unit which relates the fulcrum of a lever system and the mean of a distribution of scores. The objective, rationale, two student laboratories, and an evaluation system are outlined. Content background on statistics is offered. (MVL)

Students' conceptions of three major artificial intelligence concepts used in the modeling of systems in science, fuzzy logic, neural networks, and genetic algorithms were investigated before and after a higher education science course. Students initially explored their prior ideas related to the three concepts through active tasks. Then,…
