A Statistically Significant Determination From Pretest To Posttest In Knowledge Of Electrophoresis Concepts, Parker Megehee Nelson
Dissertations
The statistical significance from pretest to posttest of 109 high students constructing an electrophoresis chamber or not was explored. The students tested were from six intact biology classrooms. Three classes were treatment groups and three were control groups. The three biology teachers each taught a control and treatment group classroom. Except for building the electrophoresis chamber, students in both groups received identical instruction and testing. Pre- and posttest data was examined by means of a content valid test constructed by the researcher and biology teachers. In order to examine the statistical significance from pretest to posttest in knowledge of electrophoresis …
Integration Of Place-Based Education Into Science Classes From Prekindergarten Through Grade 5, Terri Adele Wade-Lyles
Integration Of Place-Based Education Into Science Classes From Prekindergarten Through Grade 5, Terri Adele Wade-Lyles
Walden Dissertations and Doctoral Studies
In a large urban district in Ohio, 29.2% of Grade 5, 28.7% of Grade 8, and 45.7% of Grade 10 students passed the state test in science. School district administrators formed a community partnership with local science institutions in order to provide students with hands-on place-based learning experiences intended to improve science academic achievement in PK-Grade 5. The purpose of this qualitative program evaluation was to determine the level of implementation of that place-based program by examining the efficacy of the teachers' embedded professional development and their experiences with the training components. Bruner's theory of cognitive development was used to …
