Ascertaining the Impact of P–12 Engineering Education Initiatives: Student Impact through Teacher Impact

The widespread need to address both science, technology, engineering, and math (STEM) education and STEM workforce development is persistent. Underscored by the Next Generation Science Standards, demand is high for P–12 engineering-centered curricula. TeachEngineering is a free, standards-aligned NSF-funded digital library of more than 1,500 hands-on, design-rich K–12 engineering lessons and activities. Beyond anonymous site-user counts, the impact of the TeachEngineering collection and outreach initiatives on the education of children and their teachers was previously unknown. Thus, the project team wrestled with the question of how to meaningfully ascertain classroom impacts of the digital engineering education library and—more broadly—how to ascertain the impacts of teacher-focused P–12 engineering education initiatives. In this paper, the authors approach the classroom impact question through probing self-reported differentials in: (1) teachers’ confidence in teaching engineering concepts, and (2) changes in their teaching practices as a result of exposure to (and experiences with) K–12 engineering education resources and outreach opportunities. In 2016, four quantitative and qualitative surveys were implemented to probe the impact of the TeachEngineering digital library and outreach on four populations of K–12 teachers’ confidence and practices, including the frequency with which they integrate engineering into their precollege classrooms. Survey results document the teacher experience and perception of using hands-on K–12 engineering curricular materials in the classroom and help create a data-driven understanding of where to best invest future resources. The results suggest that the TeachEngineering curricular resources and outreach initiatives help teachers build confidence in their use of engineering curriculum and pedagogy in K–12 classrooms, impact their teaching practices, and increase their likelihood of teaching engineering in the classroom in the future

Undergraduate Engineers and Teachers: Can Students Be Both?

Today’s college-aged students are graduating into a world that relies on multidisciplinary talents to succeed. Engineering college majors are more likely to find jobs after college that are outside of STEM (science, technology, engineering, and mathematics) fields, including jobs in healthcare, management, and social services. A survey of engineering undergraduate students at the University of Colorado Boulder in November 2012 indicated a desire by students to simultaneously pursue secondary teacher licensure alongside their engineering degrees: 25 percent ‘‘agreed’’ or ‘‘strongly agreed’’ that they ‘‘would be interested in earning grades 7–12 science or math teaching licenses while [they] earn [their] engineering degrees. As colleges of engineering education, how can we support the success of our students in these multidisciplinary fields post-graduation, including teaching? The University of Colorado Boulder’s College of Engineering and Applied Science in partnership with the School of Education, has developed an innovative program that results in graduates attaining a secondary school STEM teacher license concurrently with an engineering BS degree. This streamlined pathway through engineering educates and prepares a workforce of secondary teachers capable of high-level teaching in multiple STEM subjects—either engineering coupled with science (biology, chemistry, and physics), or engineering coupled with mathematics. These engineers are motivated and inspired to pursue two career routes because they find value and passion for both professions. One study showed that successful mathematics and science teachers ‘‘would have liked to be engineers’’. Teachers expressed that being comfortable and understanding engineering phenomena is a barrier to why they initially did not pursue an engineering career. We are fostering students that develop both an engineering mindset alongside a commitment to giving back through secondary teaching in this program. This research aims to discover if and how students in the engineering + teaching program identify themselves as both an engineering student and as a teaching student. We are exploring why students decided to pursue engineering and teaching and how they plan to use engineering, teaching, or both in their futures. It is important to also understand how we attract students to this program. Given the diverse student experience inherent in this degree program built around passion and desire to combine engineering and teaching, the paper addresses the questions, ‘‘How do engineering knowledge and teaching knowledge intersect for undergraduate engineering students?’’ and ‘‘What challenges exist to navigating an engineering major with a teaching license pathway?’’ Initial survey and focus group data collected this past academic year indicates that students in this degree program identify as both an engineer and a teacher. Using mixed-methods analysis informed by current education research—including quantitative and qualitative survey questions and small focus groups—we explore the ways in which students discovered this program and how they plan to incorporate the two disciplines in their future. We are interested in how engineering students will incorporate the knowledge that they learned in engineering classes into the lesson plans they design for secondary classroom students

Genome-wide association studies in ancestrally diverse populations: opportunities, methods, pitfalls, and recommendations

Genome-wide association studies (GWASs) have focused primarily on populations of European descent, but it is essential that diverse populations become better represented. Increasing diversity among study participants will advance our understanding of genetic architecture in all populations and ensure that genetic research is broadly applicable. To facilitate and promote research in multi-ancestry and admixed cohorts, we outline key methodological considerations and highlight opportunities, challenges, solutions, and areas in need of development. Despite the perception that analyzing genetic data from diverse populations is difficult, it is scientifically and ethically imperative, and there is an expanding analytical toolbox to do it well

Transancestral GWAS of alcohol dependence reveals common genetic underpinnings with psychiatric disorders

Liability to alcohol dependence (AD) is heritable, but little is known about its complex polygenic architecture or its genetic relationship with other disorders. To discover loci associated with AD and characterize the relationship between AD and other psychiatric and behavioral outcomes, we carried out the largest genome-wide association study to date of DSM-IV-diagnosed AD. Genome-wide data on 14,904 individuals with AD and 37,944 controls from 28 case-control and family-based studies were meta-analyzed, stratified by genetic ancestry (European, n = 46,568; African, n = 6,280). Independent, genome-wide significant effects of different ADH1B variants were identified in European (rs1229984; P = 9.8 x 10(-13)) and African ancestries (rs2066702; P = 2.2 x 10(-9)). Significant genetic correlations were observed with 17 phenotypes, including schizophrenia, attention deficit-hyperactivity disorder, depression, and use of cigarettes and cannabis. The genetic underpinnings of AD only partially overlap with those for alcohol consumption, underscoring the genetic distinction between pathological and nonpathological drinking behaviors.Peer reviewe
