Procedure And Structure For An Instructional Laboratory Which Supplements Research, R. S. Adams Jr.
Journal of the Minnesota Academy of Science
This paper describes the organization of a laboratory course in Soil Chemical Analysis. Students select and pursue small research problems to gain experience in the soil analyses that are discussed in lecture and required in the laboratory. Involvement of the class in an actual research problem proved challenging to both the instructor and the class. The data obtained often supplemented current departmental research. Individual projects were found to be easier to supervise than team problems. This paper reports results of a team project examining parameters of a pot experiment. Shape of the pot, methods of watering, methods of fertilizing, and …

This investigation compares achievement of ninth grade students in biology taught by inductive laboratory experiments, by deductive laboratory exercises, and by demonstration of inductive experiments. It appears that the inductive approach produced significantly greater attainment of attitudes of science. The emphasis of this on designing experiments and analyzing the data did not distract from the ability of students to learn and apply facts and principles. None of the instructional methods tested was found to be more effective with any particular ability range. Students in laboratory classes reacted more positively to their instruction than did those taught by the demonstration method.
