Do Honey Bees Learn To Work? (An Excerpt From Sophomores And Honey Bees), Richard F. Trump

Iowa Science Teachers Journal

Another question that your students can answer for themselves is whether bees really inherit their work behavior. That's what we tell our students - that bees are creatures of instinct. And expect our students to believe it. We all know, of course, that too much of our teaching is like that. The least we can do is to offer evidence. Better yet, we can give the students a chance to see for themselves.

High School Biology Training And Introductory College Biology Success, Stanley Whelchel, David Pettus

Iowa Science Teachers Journal

High School biology teachers are occasionally concerned with curriculum problems such as: 1. Should BSCS biology be introduced in the curriculum, and if it is, will the students do well in the introductory biology courses in college? 2. Should two biology courses be offered at the high school level, and will the second course really prepare a student better for college biology?

Elementary Science Projects And The Low Group Of Ninth Graders, Richard D. Mcvey

Iowa Science Teachers Journal

For many years it has been a common practice in junior high schools to group children according to their ability. In the science class, as well as in the other areas, this has had its advantages and disadvantages. To motivate the student in the low group is a different type of problem than to motivate the students of the average- or high-ability group.

Rallying Cry For Truly Logical Animal Lover, Michael O'Donnell

Iowa Science Teachers Journal

On attending a recent animal-protection rally, I noticed that a great deal was said about outrages against the nobler and cuddlier animals but nothing at all about the daily slaughter of many millions of microorganisms. I have therefore composed an anthem which I hope will prove a rallying cry for the truly logical animal lover.

A Survey Of Changing Of Units Of Measure In First Grade Through Eighth Grade Mathematics Materials, Thomas E. Anderson

All Master's Theses

It was the purpose of this study (1) to compare the ability of eighth grade students to change units of measure in the English system and in a fictional system of measurement; (2) to survey four mathematics textbook series, grades one through six, and four series, grades seven and eight, on changing of units of measure; and (3) to survey three college level textbooks, which could possibly be utilized in an arithmetic methods course, to see how changing of units of measure is suggested to be taught to children.

Into The Crystal Ball For The 1970s, Joe R. Moore

Iowa Science Teachers Journal

The beginning of a new decade is always an ideal time to reflect upon the past-and the future. Looking back, the decade of the sixties can be characterized as the decade of tumult, the decade of change, the decade of progress-and depending upon one's past experiences-many other adjectives will probably be equally descriptive.
