A cultivar comparison study was conducted to identify similarities
and differences in cane characteristics between 2 primocane fruiting
red raspberry cultivars and to determine if the differences and
similarities can help determine cultural practices that may improve
productivity. The comparison of the cultivars 'Amity1 and 'August
Red' showed a difference...
Producers in the Willamette Valley of Oregon are interested in growing canola as a rotational crop in grass seed and cereal rotations. Many other Brassicaceae seed crops also are produced within the valley. Concerns of seed persistence and volunteer contamination of Brassicaceae seed crops prompted the investigation of seed persistence...
The purpose of this study was to understand how instruction in an introductory nonmajor astronomy course at Oregon State University affects how non-science majors view science and the scientific process. The study used research-based methods to design a reform-based lecture/lab course and implement it for students. Two top-level questions were...
The National Research Council has aggregated research evidence on the pedagogy of science teaching and learning (NRC, 2012), culminating in the Next Generation Science Standards (NGSS). These standards support emphasis on eight scientific practices as an important component for teaching science as inquiry to K-12 students. This latest framework for...
Reform in science education has often emphasized task-based learning as an instructional method to improve student understanding and retention of concepts, and to promote the development of reasoning and problem-solving. Yet studies assessing student knowledge at the beginning and end of a task-based class show mixed results. Students in task-based...
The purpose of this study was to investigate the development of an interactive
aquarium design motivated by the employment of an innovative technology used in
scientific research. The study was informed by research on free-choice learning
describing the effects of interactive devices on visitor learning, engagement, and
attitudes. The researcher...
Recent reports at the state, national, and international level have called for increased earthquake and tsunami education to increase knowledge of the causes of these hazards, risks from these hazards, and preparedness measures to reduce risk and increase resilience to these hazards. One recommended approach to meet this need is...
Collegiate student's conceptual distinctions of what define a mathematical and a physical model seems to be affected by the epistemological beliefs they hold about this knowledge. These beliefs seem to influence student's thinking and reasoning as they embark on problem solving activities in collegiate mathematics. Student's epistemological beliefs of mathematical...
