Coshocton district in Ohio takes part in an unusual experiment that pays students who pass or scores high in the state exams. Pupils here in grades 3 through 6 earn $15 for every "proficient" score and $20 for "accelerated" or "advanced" scores. With annual tests given in five subjects, students can earn up to $100 if…

The work reported here is in the educational domain and deals specifically with the observation of instrumented pedagogical activities. Our objective is to observe learner behaviour within a web-based learning environment and to understand it. In some cases, this understanding can lead to improve the learning scenario itself. In this article, we…

Conventional testing systems usually give students a score as their test result, but do not show them how to improve their learning performance. Researchers have indicated that students would benefit more if individual learning guidance could be provided. However, most of the existing learning diagnosis models ignore the fact that one concept…

Describes four physics experiments including "Investigation of Box Resonances Using a Micro"; "A Direct Reading Wattmeter, DC or AC"; "Exercises in the Application of Ohm's Law"; and "Hysteresis on Gas Discharges." Discusses procedures, instrumentation, and analysis in each example. (CW)

Discusses the importance of teaching about enzymes in chemistry. Mentions several applications of enzyme technology to other fields. Describes an experiment involving the immobilization of yeast cells as a biocatalyst for the ethanol production from glucose. Argues for more biotechnology to be integrated into basic chemistry courses. (TW)

This study is concerned with different forms of assessment of pupils' skills in experimentation. The findings of three studies are reported. Study 1 investigates whether it is possible to develop reliable multiple-choice tests for the skills of forming hypotheses, designing experiments and analysing experimental data. Study 2 compares scores from…

The topic of inquiry is explored in an online freshman level introductory biology course for non-majors. The research took place in a distance learning program at a small community college in the Southeast. Students in the course were required to complete an extended guided inquiry in their homes and to communicate about their work by way of the…

The creative application of low-cost, readily available materials and techniques promotes inclusion and provides accessibility in the classroom and laboratory for students who are blind or have low vision. Difficulties encountered by these students include operation of laboratory equipment, execution of ordinary laboratory procedures, and use of…

There are obstacles to teaching science; however, these obstacles are not insurmountable. One obstacle is the students themselves. Students often labor under the misconception or anxiety that the course material will be too difficult to understand, or boring (mind-numbing), or that the information learned will not be applicable in their day-to-day…

With an eye towards a potential scientific ethics curriculum, this paper examines four contrasting discourses regarding the ethics of using human subjects in science. The first two represent official statements regarding ethics. These include the U.S.'s National Science Education Standards, that identify ethics with a professional code, and the…

A proliferation of new government regulations and other events in recent years has made it more and more difficult to teach science and engage in science activities. Rapid advances in biotechnology have made it difficult for both students and teachers to stay abreast of current events. These difficulties along with others have turned some teachers…

This book contains 23 suggestions for experiments involving environmental science that can be used to create a science fair project. Aimed at grades 10-12, a wide range of environmental topics is covered. These topics include soil ecosystems, aquatic ecosystems, applied ecology, global warming and the greenhouse effect, deforestation and…

This book contains simple experiments through which students explore air and its properties. Some of the topics discussed include alternative energy, bacteria, carbon dioxide, motion, weather, and flight. Experiments include: blowing a balloon up in a bottle; seeing air in water; making a lunch-bag kite, weather vanes, and paper glider;…

This book contains classroom experiments designed to promote group skills. Each lesson has 4 parts: a 3-minute set-up; 5-minute warm-up, 25-minute experiment, and 5-minute clean-up. During each part, each member of the group is responsible for performing a specific task. Included are 34 labs that cover a range of topics: observations, physical…

In these years of shortened budgets, teachers are becoming more and more inventive in designing science teaching tools and experiments. This manual contains instructions for building a few such tools, either invented or improved on by teachers affiliated with the Institute for Chemical Education (ICE). The tools are created from low cost and…
