Described is a reliable and predictable laboratory experiment which represents the result of an integrated approach to design with an emphasis on teaching. Notes the flat-celled rig has logged over 100 hours service in 2 years without any problems. (MVL)

The main advantage of using these concepts lies in the reduction of algebraic work involved in solving certain dynamics problems. A brief analytical treatment of the acceleration center and a description of a virtual work principle for equipollent systems in the kinetics of rigid bodies are provided. (MVL)

Discusses the use of computers in chemistry courses at the United States Military Academy. Provides two examples of computer projects: (1) equations of state, and (2) solving for molar volume. Presents BASIC and PASCAL listings for the second project. Lists 10 applications for physical chemistry. (MVL)

Discussed are problems encountered when a gas absorption experiment with strong measurement error is used. Notes students either avoid the experiment or report it as defective. Provides ideas to make lab experiments more instructive. (MVL)

Describes a demonstration showing the chemical reversibility between the chromate and dichromate ions. Includes reaction equations and listing of equipment needed. Recommends a demonstration for illustrating Le Chatelier's principle and stoichiometric relationships. (ML)

A study with 45 British undergraduate and graduate science students investigated the usefulness of a semistructured workshop interview to identify students' concept difficulties in chemistry, their understanding of the use of analog models, and other science education issues. Implications for use of the workshop interview technique are considered.…

We are developing a new activity-based unit on global warming and the environment as part of the "Explorations in Physics Curriculum." We describe the current status of this unit, which focuses on helping students understand the greenhouse effect and its relationship to global warming. We outline several problems encountered in testing the unit…

Good teaching highlights underlying connections between creation and dissemination of knowledge. Analysis of successful biology departments for underlying themes in improving undergraduate education led to the following conclusions: the best kind of teaching is one-on-one; change must be firmly grounded at the departmental or programmatic level;…

Research experiences are becoming increasingly available for undergraduate science students. Although many undergraduate research programs are designed with assessment-friendly outcomes as stated goals, a more personalized approach in goal setting can help administrators and mentors design fulfilling experiences for their students. Implementation…

Despite rising enrollments, college biology education has until recently lagged behind other science disciplines in reforming undergraduate instruction. However, new approaches are emerging, including introductory classes that focus more on concepts, laboratory assignments that are increasingly sophisticated, and more in-depth curricula for…

Just-in-Time Teaching (ITT) is a teaching and learning approach that combines the best features of traditional in-class instruction with the communication and resource potential available via the Web. We describe here how ITT can be used to teach biology to undergraduate and graduate level students, both science majors as well as non science…

The 7th International Conference on Education Data Mining held on July 4th-7th, 2014, at the Institute of Education, London, UK is the leading international forum for high-quality research that mines large data sets in order to answer educational research questions that shed light on the learning process. These data sets may come from the traces…
