Nebraska Tractor Test 1110 John Deere 4430 Quad -Range Diesel, Nebraska Tractor Test Lab

Nebraska Tractor Tests

All lest result s were determined from observed data obtained in accordance with SAE and ASAE test code or official Nebraska test procedure. First and second gears were not run as it was necessary to limit the pull in third gear to avoid excessive slippage. Fourth, tenth, eleventh, twelfth, thirteenth, fourteenth , fifteenth and sixteenth gears were not run as test procedure requires only six travel speeds. During maximum drawbar run in 3rd gear the transmission came out of gear twice making it necessary to hold the shift lever in place to complete the run.

Integrating Selected Principles Of Evolution Into The High School Curriculum, Judy Kareen Lyons

Graduate Student Research Papers

The purposes of this paper will be (1) to present selected biological principles pertaining to evolution, (2) to indicate curricular areas in the high school into which general aspects of evolution might be integrated, and (3) to denote specific phases of biology especially suited for teaching particular principles.

An Experimental Study Of The Effectiveness Of The Developmental Mathematics Course At Lehigh County Community College, Robert G. Clark

Walden Dissertations and Doctoral Studies

The primary purpose of this study was to determine the effectiveness of the Developmental Mathematics program at the Lehigh county Community College. There was no positive evidence that the existing method of selecting students and/or the material content of the course was affective in achieving its stated objective; that of bringing the skill and ability of weak students needing remedial treatment up to the minimum level required for probable success in first-year college mathematics. The general hypothesis posed was that the students who took the Developmental Mathematics course would perform better in first-year college mathematics than those students whose ACT …

The Regular Polyhedra: A Study In Visual Aids For Teaching Geometry, Sammye Halbert

Honors Theses

Traditionally, mathematics, past simple addition, subtraction, multiplication, and division, has been taught of as being so boring, irrelevant, and in short, one of the unavoidable evils of school. An advertisement in The Mathematics Teacher expressed the general attitude of many students when it said, "mathematics was invented by an old magician in the desert who, with the help of his talking monkey, bakes equations and cupcakes in the hot sun." It seems that many students think mathematics is just one problem after another that has some mystical answer floating around in the air somewhere. The object is to get that …

Materials To Supplement An Individualized Mathematics Program, Virginia Condon

All Graduate Projects

This project represents an attempt to develop some materials to supplement the Addison-Wesley Mathematics Program for Grade 2. The commercial program, as it stands, is conceptually sound. Operationally, however, it in many cases did not satisfactorily meet the needs of the individual students of the classroom.

Therefore, the basic material was retained (i.e., student workbooks, teacher's manual, unit tests). Materials have been developed which allow some individualization in the presentation of the concepts, self-pacing by the student, testing devices, working conditions, manipulative materials, and follow-up worksheets. These terms are further explained in the pages that follow, as well as their …

Dear Iowa Science Teacher, Gary E. Downs

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.

Information Needed, Milbert Krohn

Iowa Science Teachers Journal

One of the current fads spreading through the schools of Iowa is the attention being given to mysticism. The science teacher can do a great deal to give the youth of our schools the proper attitude to deal with the technics of the occult. One of the sessions of the Science Teaching Section of the spring meeting of the Iowa Academy will be related to dealing with the problems of the occult.

A New Approach To The Training Of Chemistry / Physics Teachers, Kenneth E. Borst

Iowa Science Teachers Journal

In 1950, during my first week as a junior high school science teacher, it became apparent to me that my training to become such a teacher was almost a complete waste of time. I have also observed that there has been very little effort on the part of colleges to change the situation.
