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 …

The Impact Of Bscs Biology And Other Modern Innovations Upon The High School Curriculum, Brian E. Boettcher

All Graduate Theses, Dissertations, and Other Capstone Projects

The need for a reorientation of science teaching in the high schools of America has been apparent since the 1940 1s. Due to this, the Biological Science Curriculum Study, hereafter referred to as BSCS, developed as a result of action by the Committee on Education of the American Institute of Biological Sciences. Large numbers of public schools in Minnesota have implemented BSCS and other innovations in an attempt to make their biology program a better one. The primary purposes of this study were:

1. To determine what innovations in biology teaching have helped to produce these changes. 
2. To determine the impact …

"What Does Membership Mean To The Elementary Teacher?", Gordon Wagner

Iowa Science Teachers Journal

At a recent in-service meeting in our school, an elementary teacher told me, "We have specialists in our school system who come into my classroom to teach art, music, and physical education. No one helps me teach science! What chance do I have keeping up with the changes in science when I only have a few credits in the first place?"

The Prediction Of Geometry Grades For Seven Linn County, Iowa, Schools, Bernice Rosemary Barrow

Dissertations and Theses @ UNI

It was the purpose of this investigation (1) to determine the relative value of the Algebra I grade, the Iowa Tests of Educational Development quantitative thinking score, and the Iowa Tests of Educacational [sic] Development composite score in predicting the geometry grade, and (2) to present the findings, using two predictor variables, that would provide the best possible estimate of success in geometry. The study involved 219 students in seven schools in Linn County, Iowa, who were enrolled in geometry in 1966-67. Selection of the schools was made on the basis of information about the Algebra I and geometry textbooks …
