The purpose of this study was to develop an instrument to provide valid and
reliable measures of misconceptions in the area of photosynthesis and respiration
among fourth, fifth, and sixth grade students in Thailand. A 17-item, two-tier
multiple-choice test was developed and validated using construct-related evidence to
determine the appropriateness...
The purpose of this study was to determine the
effects of frequent versus conventional testing on

the University...
The purpose of this study was to determine if
computer assisted instructional (CAI) tutorials in high
school biology differ in effectiveness in terms of
student academic achievement when compared with the more
traditional lecture/discussion type of instruction.
Additionally, student attitudes toward CAI were measured
using a student attitude questionnaire.
The...
The purpose of this study was to investigate several hypotheses concerning specific demonstrable attitudes toward education, critical thinking ability, and affective behaviors as these were manifested by students in the BSCS environmental module, Investigating Your Environment (IYE), and in more structure-oriented biology classes. Participants in the study were students in...
The purpose of this study was to investigate: (1) whether the use of the Motions computer program will be more effective in the acquisition of transformation geometry concepts in eighth-grade students than the use of the Mira hands-on manipulative, (2) whether the use of the Motions computer program will be...
The purpose of this study was to investigate an application of
statistical concepts to quality control of highway construction. The
application was presented qualitatively and demonstrated quantitatively
by an investigation of asphalt content in asphalt concrete.
For the example, an Oregon State Highway Project was
sampled and tested. The average...
Cardicola alseae is a blood dwelling trematode found in the
fishes Salmo clarki henshawi and Salmo gairdneri gairdneri. Eggs
which were ovoid in shape and non-operculate left the adult and passed
to the gill capillaries of the secondary lamellae. The miracidium was
ovoid, 0.070 mm. long by 0.052 mm. wide,...
