A Comparison Of The Effects Of A Team Approach And A Conventional Approach On Achievement In High School Biology, Paul Joslin, John Montean, John Schmitt

Iowa Science Teachers Journal

It is very easy to come by reports in support of almost any new practice in education. Teachers would rather report favorable results and journals would rather print them. It was the many published reports enumerating the advantages of team teaching that first interested us in a team teaching experiment. At the time we started in 1964, we summarized 141 publications with team teaching in their titles. There are only a limited number of advantages and disadvantages that can be hypothesized for any particular practice. It was not surprising, therefore, to find that recent reports tend to merely reassemble what …

A Simple Machines Lab For Seventh Grade Students, Peter H. Sweedy

Iowa Science Teachers Journal

Having taught physical science for two years at the high school level, my new assignment to teach seventh grade science was met with mixed emotions. I had heard that junior high students were very energetic (mostly for mischief) and were very limited in learning ability, due to a low reading level and a lack of mathematical skills. I know I had also wondered, like many of you in high school and college teaching, just why did high school age students have such poor concepts of motion, energy, light, sound and graph interpretation and use.

New Istj Format, Robert E. Yeager

Iowa Science Teachers Journal

The financial problems of the Iowa Academy of Science caused the Board of Directors to approve a budget for 1972-73 which decreased the support for the Iowa Science Teachers' Journal by nearly two-thirds. As a result of this austerity program it was necessary to alter the format, size and printing for Volume 9, No. 4 of the Journal. Several alternatives were considered before the ISTJ editorial board recommended a new format to the IAS Publication Committee. This issue represents the recommended and approved format which will characterize the next three issues of Volume 10 as well.

So You Want To Be An Outstanding Teacher!, Barton Philipps

Iowa Science Teachers Journal

Great teachers are great because of the long vacations, short working day, easy work (if you call it work), and good pay. WHAT? Who said that? Truly GREAT teachers rarely take a vacation and work overtime without pay, to guide the students in learning situations. And as for the pay, the garbage collectors in many areas make more than the teachers.

Production Of A Video Tape Recorded Supplement For Use In Teaching Electrical Tuned Circuit Theory, William A. Carlson

All Master's Theses

This paper presents a sample of the proceedures utilized to produce a video tape recorded suppliment for use in teaching electrical tuned circuit theory. It is designed so that it could be used as a ready reference for anyone desiring to make a video tape recorded teaching aid. A recomendation is that, with the advent of the simplified video tape recorder, every teacher should become as practiced in its operation and utilization as he now is with the film projector.

A Comparative Investigation Of The Effects Of Frequent Testing Upon Achievement In Secondary Advanced Algebra, John Thomas Fullerton

All Master's Theses

Relatively speaking, few studies have concerned themselves with the problem of frequent testing, and as Keys pointed out, empirical evidence, uncomplicated by differences in the amount of testing material employed, on the effects of frequent testing is, at best, scarce (14:427). Also many studies used tests and test results for direct instruction, thus introducing additional variables. Furthermore, the choice of subjects and disciplines has been limited, the better part being taken from college psychology and sociology classes or high school science classes. This investigation was not an attempt to modify previous experiments, nor was it an attempt to identify which …

A Comparative Investigation Of Understanding Of Ecological Content Between Eighth And Tenth Grade Pupils, David Lee Herbenson

All Master's Theses

The study had two major purposes. One purpose was to determine if Covington Junior High School eighth grade pupils understood the basic ecological ideas and facts presented to them in a teacher-designed one semester course entitled Environmental Concepts Orientation (ECO). The second purpose was to find out the degree of competence attained by the eighth grade pupils as compared to tenth grade pupils taking a one year ecologically oriented course in the nationally developed Green Version BSCS biology series at Camas, Washington.

An Evaluation Of An Early Introduction Of Algebra I To Junior High School Students On An Extended Basis, Ralph H. Peterson

All Master's Theses

The purpose of the study is to evaluate the program of mathematics for eighth grade students that provides for an early introduction to Algebra I. The study will (1) gather evidence needed upon which to base a decision to continue the type of grouping described above, and (2) gather evidence to determine changes in the students' attitudes and interest concerning mathematics in general.

Final Examination Scores In Algebra As A Function Of Retesting, Otto Francis Ruud

All Master's Theses

Many teachers as well as students feel that our system of evaluation is far from perfect, but these same people have offered no alternative workable plan which would in whole or in part relieve the objections. Hopefully this study will demonstrate a philosophy of the teaching of mathematics in conjunction with a companion plan of evaluation which will relieve many of the basic objections while at the same time produce more learning. The philosophy that a more cooperative attitude in regard to assignments, testing, and make-up work are more conducive to learning is the basic aspect of this study. It …
