Changes In A Prairie Bird Population From 1940 To 1989, Neil P. Bernstein, Kristine K. Baker, Sherry R. Wilmot Jan 1990

Changes In A Prairie Bird Population From 1940 To 1989, Neil P. Bernstein, Kristine K. Baker, Sherry R. Wilmot

Journal of the Iowa Academy of Science: JIAS

We repeated a bird census of a prairie/field community that was done by Kendeigh (1941) in 1940. Changes in the bird populations were compared with changes in vegetation, agricultural land use for the county, and trends in urbanization. Grassland birds did decline in abundance due to causes similar to those cited in other studies. The increase in forest and edge nesting species was more unusual to this study, and probably correlated with the woody succession that had occurred.

This book discusses the writing of the tests, the analysis of results, and the reporting of results to parents, teachers and schools. The aim of the basic skills tests is to describe, in positive terms, the skills that students have mastered, to identify …


The Relationship Between Cooperative Small Group Composition And The Learning Of A Mathematical Concept In The Primary School Years: A Pilot Study, Susan Eaton Jan 1990

The Relationship Between Cooperative Small Group Composition And The Learning Of A Mathematical Concept In The Primary School Years: A Pilot Study, Susan Eaton

Theses : Honours

In recent years small group cooperative learning has been given increasing attention by researchers. This interest has been a result of n growing awareness of the benefits that small group cooperative learning can bring to the learning process. These benefits include gains in areas of academic achievement, self-confidence as a learner, cross-cultural/cross-racial relationships, social acceptance of mainstreamed students, and improved attitudes towards school and learning. A particular focus of North American researchers has been small group cooperative learning in mathematics. Little work had been done in this area in Western Australian schools and with the changed emphasis in the Western …


The Effect Of A Vee-Mapping Strategy On Students' Perceptions Of Laboratory Activities, Sonia J. Hueppauff Jan 1990

The Effect Of A Vee-Mapping Strategy On Students' Perceptions Of Laboratory Activities, Sonia J. Hueppauff

Theses : Honours

Practical work is considered important for learning science, by teachers and science educators. This acceptance though, has been reported as based on intuition rather than evidence (Atkinson & White, 1961). A significant proportion of class time is occupied with doing practical work. It is evident that in a majority of situations, students commence laboratory activities unsure of their aim, the procedure they are going to carry out, or that experimentation is a way of forming knowledge (Moreira, I 960; Novak & Gowin, I 964). Vee-maps (Novak & Gowin, 1 964) are one way of making laboratory work more meaningful. That …


Astronomy Resources, Thomas Hockey Jan 1990

Astronomy Resources, Thomas Hockey

Iowa Science Teachers Journal

The concept of orbiting bodies is complicated by the fact that no real system exists--be it satellite and planet, planet and sun, of binary stars--in which one object revolves around the center of the other. Rather, both bodies revolve about a common center of mass. The idea of center of mass enters into discussions of dynamics throughout an astronomy course or unit, beginning with the motions of the Solar System and recurring in analyses of stellar systems and of galaxies


Astronomy Resources, Thomas Hockey Jan 1990

Astronomy Resources, Thomas Hockey

Iowa Science Teachers Journal

Understanding why an orbiting satellite neither travels in a straight line away from the body about which it is revolving, nor falls inward toward it, is an important concept in both astronomy and physics. Demonstrating an orbit in a classroom is made difficult by the Earth's gravity. The Earth's gravity can be used, along with simple kitchenware, to create a model of a planetary or satellite orbit.
