Japanese lesson study, in various adapted forms, is becoming increasingly significant in professional development of mathematics teachers in the USA. Our goal in the research reported in this paper was to investigate, in a three-tiered teaching experiment, the cycles of learning of two researchers, six teachers, and the students in three grade 4…

Language teachers with little or no experience in conducting research are guided through the process of deciding what kind of classroom research to undertake, and how to organize and implement it. In question-and-answer format, four types of research are defined and explained separately: action, survey, correlational, and experimental studies. For…

This monograph contains 10 plant pathology experiments that were written to correspond to portions of a biology curriculum. Each experiment is suitable to a biology topic and designed to encourage exploration of those biological concepts being taught. Experiments include: (1) The Symptoms and Signs of Disease; (2) Koch's Postulates; (3)…

This booklet introduces guidelines for teachers at any grade level to set up and maintain a simple aquarium and through it introduce simple biological ideas to their students. Natural and cost-saving aquarium-running strategies are discussed and common, hardy fish and plant choices are described. Many demonstrations and experiments are included on…

What if you could build a machine that could make it's own fuel, adapt to changing conditions, and generate priceless products like air and water? Over millions of years, vascular plants have developed roots, stems and leaves that work together to perform these feats, as well as provide energy for every living thing on Earth! In Plant Structure…

Building on the scientific and investigative knowledge that students acquire over the years, this program delves deeper into the theory of "science as inquiry". This program helps students recognize the intricate relationship between explanation and evidence through engaging examples. Students trace the path of scientific inquiry--guided by…

This curriculum unit revolves around the intriguing nature of dry ice and the incessant curiosity it provokes in all those who have the opportunity to interact with it.
