Assessing The Effects Of An Authentic Project-Based Intervention On Secondary Students’ Understanding Of Ecosystems And Their Attitudes Toward And Interests In Stem, Kenneth Rolland Thompson
Assessing The Effects Of An Authentic Project-Based Intervention On Secondary Students’ Understanding Of Ecosystems And Their Attitudes Toward And Interests In Stem, Kenneth Rolland Thompson
Theses and Dissertations--Education Sciences
There is a need for secondary schools to provide more authentic, hands-on experiences in science, technology, engineering, and mathematics (STEM), and specifically, project-based investigation (PBI) environments in the classroom that focus on real-world problems relevant to students’ experiences, interest, and lives that manifest the Next Generation Science Standards (NGSS) following practices they prescribe. This study investigated how, to what extent, a contextualized aquaponics PBI (APBI) 10-week model unit affected high school students’ attitudes toward STEM in general, and aquaculture and aquaponics in particular, and interests in future STEM-related disciplines and/or STEM career pathways. This study also measured changes in students’ …

A Quasi-Experimental Study Of Middle Level Student Engineering Understanding Pre-And Post-Treatment, Emily Driessen
Theses and Dissertations--Science, Technology, Engineering, and Mathematics (STEM) Education
This qualitative quasi-experimental study analyzed middle-level students’ understanding of engineering before and after instruction. Students from four teachers were examined. Before and after instruction, all students completed the Draw an Engineer Test (DAET) and the Views of Nature of Engineering (VNOE) survey. Additionally, sixteen students (eight girls and eight boys) from each group (Treatment and Comparison) were interviewed before and after instruction. Findings revealed that after instruction (1) many students viewed engineers as makers/builders/workers (just as they did pre-instruction), however, the percentage of students who listed engineers as inventors, designers, and creators increased; (2) fewer students from both groups noted …
