We describe our experience in building a remote laboratory for teaching magnetic domains. Fulfilling the proposed on-line experiments, students can observe and study magnetization processes that are often difficult to explain with written material. It is proposed that networks of remotely accessible laboratories could be integrated in the Global…

The principles, difficulties and challenges in control education are discussed and compared to the similar problems in the teaching of mathematics and systems science in general. The difficulties of today's students to appreciate the classical teaching of engineering disciplines, which are based on rigorous and scientifically sound grounds, are…

This study focused on differences between teacher-centred and learner-centred experiments in soil ecology. After a pilot study, we selected three experiments simple enough to be carried out by pupils even with little experience in self-determined learning and hands-on practice. The sample comprised 123 fifth and sixth graders from a middle school…

The authors used the 5E learning cycle (engage, explore, explain, extend, and evaluate) and a pulmonary carbon dioxide mystery to introduce eighth grade students to the study of chemistry. The activity engages students in measurement, data collection, data analysis, media and internet research, research design, and report writing as they search…

This study sought to connect the science activity educational approach to the higher cognitive development of students using a relatively new learning model, the Cultural Historical theory, based upon the work of Vygotsky. The theory advances the concept that children's intellectual development occurs in interactions with an adult or more capable…

The goal of this mini-curriculum is for students to discover what drinking water really is. Five units are designed to be presented as a lecture and to allow 30 to 40 students to perform every procedure, each testing their own tap water sample. Games are provided in each section to reinforce the concepts presented in each unit. Unit 1 introduces…

This book of life science activities introduces a new experimental animal--the WOWBug, "Melittobia digitata"--that is commonly found in nature but has never before been used in the precollege classroom. It includes 20 activities and experiments for grades 5-12, that cover topics from basic orientation to ecological interactions, from physical…

This pilot study explored the characteristics of children's co-inquiry with a mentor and the changes occurring in their questioning with prolonged engagement in mediated inquiry. Six graduate students, who were practicing teachers, acted as mentors to individual students for inquiry into child-selected topics for 10 weeks. Children ranged in age…

This document is the laboratory manual for the Physics 152 course at Purdue University. It includes a laboratory introduction, hardware and software guide, and laboratory report guide. Labs include: (1) "Measurement Uncertainty and Propagation"; (2) "Introduction to Computer Data Acquisition and Relationships between Position,…

This book contains hands-on science laboratory activities for grades 4 through 9 that use discrepant events to challenge students. All of the "puzzlers" are based upon science principles and include directions for building gadgets that explain the "puzzlers." Topics covered include: volume conservation, magnetic phenomena,…

The purpose of this investigation was to explore the ideas and beliefs of high school science students (n=37) about the processes of observation in their learning of science, and how these students approached the task of observing during their science experiments. Findings include: many students saw observation as a teacher-directed process;…

This document contains biology labs, demonstrations, and activities that use low budget materials. The goal is to get students involved in the learning process by experiencing biology. Each lab has a teacher preparation section which outlines the purpose of the lab, some basic information, a list of materials , and how to prepare the different…

From prehistoric times people have been fascinated with color; from cave paintings to the latest computers, color has been a constant companion. Textiles and craft items are made more beautiful by the alteration or application of colorants. This teaching resource investigates dyes obtained from natural sources, such as plants and animals. These…

This informational packet contains the materials necessary to administer the annual Department of Defense Dependent Schools Pacific Region Junior Science and Humanities Symposium (JSHS) at the high school and middle school levels. The symposium program is a calendar year research program which includes one week symposium of students (grade 8-12)…

The purpose of this study was to survey the quantity and quality of laboratory work conducted by Grade 11 and 12 biology students in British Columbia High Schools, to analyze student performance on laboratory based questions on Provincial examinations, and to examine the curriculum for recommended laboratory work. Examination and curriculum data…
