Presents a teaching approach that uses student group teaching wherein students teach, are rewarded for good performance and benefit from other students' academic achievement during quizzes. Discusses the scope and limitations of this approach. Includes 15 references. (YDS)

Describes the Curriculum Alignment Projects (CAPs) with the example of Bicarbonate Squeeze Play, which is an 18-week curriculum. Describes the three important outcomes of the CAPs; motivation, achievement, and teaching. Includes 16 references. (YDS)

Presents the activity of Cartesian divers which demonstrates the relationship between pressure, temperature, volume, and buoyancy. Includes both instructor information and student activity sheet. (YDS)

Explains the limitations of a traditional density experiment and presents an inquiry-based laboratory experiment which allows students to develop an understanding on the relationship between the object's properties and the volume of water the object displaces. (YDS)

Uses an inquiry-based, instructor guided teaching approach and presents the activity "Selectivity/Reactivity Principle in Terms of Hammond's Postulate". Includes 17 references. (YDS)

Introduces an industrial chemistry program aimed to provide basic skills and attitudes to incoming students. Explains the components of the program including: classwork, labwork, working as a team, and student evaluation. Includes 20 references. (YDS)

Presents an experimental procedure to measure the volume of a gas more accurately and which requires very common and inexpensive materials. (YDS)

Investigates students' conceptions on reliability and the ways of dealing with different sets of experimental data. Tests students' understanding of how to handle experimental data from three aspects; doing replicates, handling data, and judging the quality of data with respect to spread. Includes 12 references. (YDS)

Investigates the differences in academic achievement and performance for two groups of at-risk students in large and small group instructional settings when activity-based informal collaboration is applied as a teaching method. Includes 40 references. (YDS)

Investigates the reasons for low academic achievement in chemistry among Hispanics students at the college level. Focuses on gender and ethnicity and uses a 6-question instrument specifically designed to identify the reasons for lack of success. Includes 33 references. (YDS)

Describes how to construct a diver that repeatedly submerges and rises to the surface of a tub of water from a plastic disposable pipet and baking powder. (WRM)

Presents a story of a footrace between different groups of people that can be used to teach about chemical separation by chromatography. (WRM)

Presents an activity that is a qualitative version of the standard paper chromatography experiment. This activity introduces students to methods of selecting the best solvent for a separation and allows them to consider the effects of adding acid and base. (WRM)

Describes the development and implementation of a web-based software engine that selects from a database of questions for students to answer and provides immediate feedback for students and instructor. Discusses the results of using this technology in an organic chemistry section. (Contains 22 references.) (WRM)

Describes a study of high school students' and chemistry teachers' understanding of the gas laws which focused on the application of scientific concepts in practical situations instead of mathematical calculations in theoretical situations. (Contains 13 references.) (WRM)
