Explains paradigm changes and gives the example of the periodic table's evolution historically, starting from the 1800s. Questions whether students are aware of this paradigm change. (Contains 15 references.) (YDS)

Introduces a science laboratory integrating biology and chemistry courses that includes four modules: (1) the fundamental process of reactions; (2) a semester-long project on the chemical assay of ascorbic acid; (3) human metabolism of Vitamin C; and (4) an open-ended project on the manipulation of macromolecules. (YDS)

Incorporates dramatization into science teaching to explain difficult phenomena. Uses three different types of dramatization: teacher-performed dramatization, teacher-directed dramatization, and student-directed dramatization. Presents student analyses of the dramatizations. Introduces an instrument that is designed to measure student perceptions…

Investigates the reasons for data fabrication among undergraduate and graduate students. Presents several examples of getting misled by the candle and tumbler demonstration. Concludes that presented facts, concepts, or principles increase the incidence of data cooking. (YDS)

Uses the PowerPoint program instead of paper in student projects. Describes the background and procedure for project implementation. Presents students' written comments on the project and discusses the challenges of incorporating multimedia into the earth science curriculum. (YDS)

Introduces an introductory physical science course to help elementary education majors develop a realistic understanding of the nature of science. Analyzes the influence of the course on students' conceptions of scientific principles. (YDS)

Introduces a follow-up laboratory experiment demonstrating the formation change when calcium binds to calmodulin. This conformation change allows this complex to bind to a target protein. Presents the necessary information to conduct the experiment and discusses the results. (YDS)

Introduces the National Museum of Wales, Amgueddfa Genelaethol Cymru, which exhibits fine and applied art collections and science collections exploring the evolution of Wales, natural history, and the environment. (YDS)

Focuses on the importance of teamwork and describes Pennsylvania State University football coach Joe Paterno's cooperative teamwork methods. The five basic tenants of cooperation discussed include positive interdependence, face-to-face interaction, individual accountability, social skills, and group processing. (SAH)

Examines the educational benefits of an experimental project approach to students taking the last course of an introductory biology sequence. Educational benefits were defined in terms of analytical skills, knowledge of basic statistics, and experience with scientific writing. The study was viewed as a preliminary investigation, but one that…

Describes a course that requires students to work in groups to address local ecological problems of interest to a client external to the university. Students learn the skills needed to apply their knowledge and gain satisfaction by assisting others. The ecological projects provide an important source of feedback to identify the strengths of the…

Describes a high school course entitled "Science Technology in Society". High school students use live video presentations and world wide web courseware. Concludes that distance learning students performed as well as traditionally instructed students. (SAH)

Describes an interdisciplinary curriculum designed to connect math, science, and technology with students' lives. Changing students' understanding of science required building connections across disciplines, building support among colleagues, and building trust with the administration. (SAH)

Describes how conducting in-class symposia in which students present primary research articles can provide a window into the process of scientific research and communication; broaden student exposure to research; and improve their reading, writing, and oral presentation skills. The key to the success of this symposium format is allowing students…

Describes a scavenger hunt activity that stimulates active learning. Presents objectives, examples, pitfalls, grading methods, and evaluation based on course experiences with the technique. Although the method was used with lower division biology courses, it is applicable to a wide variety of science courses at various levels. (SAH)
