The purpose of this study was to critically examine the perceptions that African-American high school students have towards engineering. A qualitative research design using criterion sampling and snowballing was used to select seven African-American students from urban high schools to participate in the research. Semi-structured interviews were used to collect data from participants attending urban high schools on the east and west coast. Using Critical Race Theory (CRT) as the theoretical framework, the study was able to produce "emergent themes" from collected data. Findings from this study will help researchers understand how African-American students may perceive the field of engineering.
A focus group study was conducted with purposefully sampled student participants solving an engineering design challenge during a one-week engineering summer camp held at a research-intensive university in the southeast. The goal of the study was to further understand the student experience and ascertain the perceived value of an informal learning environment for students engaged in an engineering design challenge. Emergent themes are provided to illustrate the primary challenges related to the engineering design challenge and the aspects of the engineering summer camp that were beneficial to the student participants. It is anticipated that the results of this study will constructively add to the literature on learning and teaching in engineering design across informal and formal learning environments.
Engineering design activities offer the promise of enhanced learning and teaching in pre-college science, technology, engineering, and mathematics (STEM) settings. The wide variation and lack of coherence in research and practice concerning pre-college engineering design challenges necessitates an investigation of the literature. The overarching research question guiding this search and review of literature was, ''How are engineering design challenges conceptualized in pre-college environments?'' A search and review coupled with iterative thematic analysis was employed to understand and conceptualize the current body of literature on pre-college engineering design challenges. It is anticipated that this review will provide a general picture of the salient features surrounding engineering design challenges, including: authenticity to the learner and to engineering practices, open-ended problems, modeling, optimization to continuously improve, and the promotion of engineering habits of mind such as balancing trade-offs and satisficing. It is also expected that the results will contribute toward ongoing discussions of the role of design challenges in STEM educational settings, future research directions, and implications for practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
