A problem-solving experiment is a learning activity that uses experimental design to solve an authentic problem. It combines two evidence-based teaching strategies: problem-based learning and inquiry-based learning. The use of problem-based learning and scientific inquiry as an effective pedagogical tool in the science classroom has been well…

To learn with data, students need "data" to explore. This can be deceptive--data-rich experiences typically involve much more than a straightforward science lab. Solving real problems with data means identifying authentic questions that are meaningful to students and provide a foundation for deep inquiry. Such situations often lend…

Discusses the use of student-generated rubrics in science classes where students design their own laboratory activities to solve open-ended problems. Promotes careful consideration of what constitutes open-ended work. Presents certain rubrics and grading criteria. (JRH)

Reexamines an experiment in which the volumetric fraction of oxygen in air was supposed to have been determined. Presents challenges to the procedure. (DDR)

Describes the stages and outcomes of a junior high school science lesson on erosion and deposition utilizing a "kids as researchers" theme. Stages include awareness, discussion, investigation, experimentation, generalization, and extension. (SK)

Presents an open-ended experiment which has students exploring polymer chemistry and reverse osmosis. This activity involves construction of a polymer membrane, use of it in a simple osmosis experiment, and application of its principles in solving a science-technology-society problem. (ML)

Supports the use of a science experiment option in the high school curriculum to enhance student learning. Presents a science experiment rubric and connects the use of science projects with standards. (DDR)

Authors discuss "the scientific method" and assert that laboratory scientists ask questions but seldom state formal hypotheses to be answered by controlled experiments. Authors suggest that experimental results should not be viewed as fact, and students should not be required to memorize the steps of the scientific method. (PR)

Presents a science experiment in which students test the buffering capacity of household products such as shampoo, hand lotion, fizzies candy, and cola. Lists the standards addressed in this experiment and gives an example of a student lab write-up. (YDS)

Discusses briefly Piaget's views on intellectual development as related to science teaching. Describes intellectual activities observed in science classrooms and shows how specific science lessons can be designed to encourage cognitive development. (GA)

Describes experiences, or "lab puzzles," which will help students develop problem-solving skills in a laboratory setting. Outlines procedures for developing techniques, setting boundaries, and finding the number of molecules of water in Lake Erie. (RT)

Presents performance assessments, written by a team of Wisconsin science teachers, designed to see if students know, have practiced, and are able to perform the skills associated with science problem solving. (JRH)

Describes a minicourse on experimental hypotheses. The courses which treats the investigative nature of biology as a major theme, teaches nonrigorous problem-solving and engenders the excitement of self-discovery. Manipulation of variables in relation to controls, the principles of deduction and induction, and their application to selected…

Argues that cookbook chemistry laboratory experiments do little to teach scientific inquiry. Suggests providing students with laboratory experiences that follow the introduction of a concept and challenge students to investigate that concept through an experiment involving very few initial instructions. Lists some such challenges used in chemistry…

Describes the selection and implementation of an authentic assessment model for evaluating students' science laboratory knowledge and skills. Provides sample problems and a scoring form for the performance-based science laboratory test. (MDH)
