The purpose of the study was to prepare and statistically
evaluate a series of 11 history of science case studies designed to
teach the following abilities involved in scientific thinking:
1. Recognizing problems, hypotheses, experimental conditions,
and conclusions.
2. Understanding the relationship of evidence to hypotheses.
3. Understanding experimental conditions...
Purpose: The purpose of this study was to determine statistically the
effects of an automated science curriculum on the science learnings
of eighth grade students. This curriculum involved the use of
Keysort cards as a flexible handbook for teachers and included in
the directions for use a teaching method which...
The overall goal of this study was to identify multiple scales of habitat use and habitat electivity by redband/steelhead trout and define the limiting factors affecting the distribution patterns of this species during summer flows.
The main objective in chapter 2 was to identify the most important habitat associations that...
Water temperature is an essential property of a stream. Temperature regulates
physical and biochemical processes in aquatic habitats. Various factors related to
climatic conditions, landscape characteristics, and channel structure directly influence
stream temperature. Numerous studies indicate that increased average air temperature
during the past century has led to stream warming...
The pea crab Fabia subquadrata is frequently found as a symbiont
of mussels, living within the mantle cavity. This study examined
the nature of this symbiotic relationship by recording the pattern
of distribution of individuals in a mussel bed, testing responsiveness
to host secretions, and observing the feeding mechanics and...
The avifaunal composition of ten western Oregon forest stands located at the eastern base of the Coast Range was examined on a seasonal basis. The stands were dominated by Oregon white oak, Douglas fir or western hemlock, Avian populations were sampled monthly from January 1968 to January 1970, using permanent...
The progression and consequences of aluminum toxicity were
studied microscopically in the root tips of four wheat varieties
representing different classes of Al tolerance. The root tips studied
were collected from seedlings grown in nutrient solution cultures containing
either sublethal or lethal Al treatments which were unique for
each variety....
The purpose of this study was to statistically evaluate the
influence of student placement at reading level by means of an informal
reading inventory in one kind of elementary science materials. The
materials were written at five levels of reading difficulty to better
meet the reading ability spread found in...
This investigation was designed to provide information about
applicants to Academic Year Institute Programs at Oregon State
University.
