Despite ongoing initiatives and research efforts, the persistent underrepresentation of marginalized groups in Science, Technology, Engineering, and Math (STEM) disciplines in the U.S. has seen little improvement. This study posits that a fundamental change in teacher preparation can lead to more inclusive STEM learning environments. It centers on the development...
Just as scientific knowledge is constructed using distinct modes of inquiry (e.g., experimental or historical), arguments constructed during science instruction may vary depending on the mode of inquiry underlying the topic. The purpose of this study was to examine whether and how secondary science teachers construct scientific arguments during instruction...
Purpose of the Study: The purpose of this investigation was to measure some of the effects of an elementary science program, the Science Curriculum Improvement Study (SCIS) on science achievement of certain sixth grade students. Important to the problem was how the SCIS students compared with students exposed to a...
The purpose of the study was to analyze and compare the teaching
styles of a trial group of junior secondary science teachers
trained to use and using new materials, and a control group of teachers
using traditional materials. The new materials consisted of portable
science kits, demonstration apparatus, teacher's guides,...
The purpose of this exploratory study was to examine scientific arguments constructed by secondary science teachers during instruction. The analysis focused on how arguments constructed by teachers differed based on the mode of inquiry underlying the topic. Specifically, how did the structure and content of arguments differ between experimentally and...
The purpose of this study was to describe the development of mathematics
preservice teachers’ technology pedagogical content knowledge (TPCK) in a
subject specific, technology integrated teacher preparation program. The study also
investigated the roles of several influential components of the program and the
technology thread throughout the program in supporting...
Results of recent studies on Piagetian cognitive development,
though equivocal, showed that the architectonic of formal operational
schemata is not possessed by a sizeable percentage (up to 52%) of adolescents
and young adults. The purpose of the present study is two
fold: (i) To assess the cognitive levels of a...
This study reports on the creation and testing of a model concept-mapping process that will aid the development and documentation of ocean science educational content of The Science and Math Investigative Learning Experiences (SMILE) Program, a pre-college science and math enrichment program based at Oregon State University. The project uses...
