Computer Programming Effects in Elementary: Perceptions and Career Aspirations in STEM

The development of elementary-aged students’ STEM and computer science (CS) literacy is critical in this evolving technological landscape, thus, promoting success for college, career, and STEM/CS professional paths. Research has suggested that elementary- aged students need developmentally appropriate STEM integrated opportunities in the classroom; however, little is known about the potential impact of CS programming and how these opportunities engender positive perceptions, foster confidence, and promote perseverance to nurture students’ early career aspirations related to STEM/CS. The main purpose of this mixed-method study was to examine elementary-aged students’ (N = 132) perceptions of STEM, career choices, and effects from pre- to post-test intervention of CS lessons (N = 183) over a three-month period. Findings included positive and significant changes from students’ pre- to post-tests as well as augmented themes from 52 student interviews to represent increased enjoyment of CS lessons, early exposure, and its benefits for learning to future careers

An Examination of the Correlation of Exploring Computer Science Course Performance and the Development of Programming Expertise

This study investigated patterns in the development of computational thinking and programming expertise in the context of the Exploring Computer Science (ECS) program, a high school introductory CS course and professional development program designed to foster deep engagement through equitable inquiry around CS concepts. Prior research on programming expertise has identified three general areas of development --- program comprehension, program planning, and program generation. The pedagogical practices in ECS are consistent with problem solving approaches that support the development of programming expertise. The study took place in a large urban district during the 2016--17 school year with 28 ECS teachers and 1,931 students. A validated external assessment was used to measure the development of programming expertise. The results indicate that there were medium-sized, statistically significant increases from pretest to posttest, and there were no statistically significant differences by gender or race/ethnicity. After controlling for prior academic achievement, performance in the ECS course correlated with performance on the posttest. With respect to specific programming concepts, the results also provide evidence on the progression of the development of programming expertise. Students seem to develop comprehension and planning expertise prior to expertise in program generation. In addition, students seem to develop expertise with concrete tasks prior to abstract tasks

Does a Taste of Computing Increase Computer Science Enrollment?

The Exploring Computer Science (ECS) high school curriculum is designed to foster deep engagement through equitable inquiry around computer science concepts. We have shown that students find ECS courses personally relevant, are increasing their expectancies of success and perceived value for the field of computer science, and are more likely to take another computing course

Approaches to Broadening Participation with AP Computer Science Principles

The Advanced Placement Computer Science Principles (AP CSP) course framework was created with the intention of broadening participation in computing. Research has produced mixed results on whether or not the framework succeeds in that goal. Given that teachers have significant freedom in how they choose to teach the AP CSP content, students can have a variety of experiences that may or may not impact their continued participation in CS. In this paper, I compare four different approaches to the AP CSP framework by examining their impact on AP exam scores, self-efficacy and confidence, belongingness and identity, and persistence and interest, to examine how these approaches might impact those traditionally underrepresented in CS. I also discuss how social and curricular interventions may differ in outcomes

Female computer science and engineering undergraduates: reflections on participation in the academic landscape

Women continue to be underrepresented in computer science and technology related fields despite their significant contributions. The lack of diversity in technology related fields is problematic as it can result in the perpetuation of negative stereotypes and closed-minded, unchecked biases. As technology tools become integral to our daily lives it is essential that a diverse group of people contribute to the sociocultural environments where we participate and live. This dissertation is a phenomenological, interview-based, study designed to investigate the lived experience of women in undergraduate computer science and engineering programs. The purpose of this study was to better understand the factors that might encourage or discourage the participation women in the major and in the field. In order to grow the number of women in technical fields it is important to first understand what attracts them to the field and what supports they find helpful or not helpful. This study illuminated some recommendations that might guide the work of practitioners in secondary schools as well as higher education. Among other things, participants appreciated being challenged by the content and assignments, feeling support from faculty and peers, feeling a connection to the culture, effective encouragement to persist, and engaging interactions. All of the participants described having gone into their field to make a positive impact on society and they also all described the importance having at least one supportive female mentor. Participants described the importance of having spaces where they felt included and appreciated their professors and peers who pushed back against the historical CS-world stereotypes. While the experience of each participant was unique, and there were some very negative experiences, all six participants reported having mostly positive experience in their undergraduate programs

Saving Bees with Computer Science: a Way to Spark Enthusiasm and Interest through Interdisciplinary Online Courses

In computer science education (CSEd) it is a well-known challenge to create learning environments in which everyone can experience equal opportunities to identify themselves with the subject, get involved, and feel engaged. Especially for underrepresented groups such as girls or not computer enthusiasts, CSEd seems to lack sufficient opportunities at its current state. In this paper, we present a novel approach of using interdisciplinary online courses in the context of bee mortality and discuss the possibilities of such courses to enhance diverse learning in CSEd. We report summarized findings from a one-year period, including 16 workshops where over 160 secondary school students (aged 10-16) have participated in our online courses. Pre-test-post-test surveys have been conducted to gain insights into students\u27 perceptions and attitude changes. The results show the potential of such interdisciplinary approaches to spark interest in computer science (CS) and to rise positive feelings toward programming. Particularly striking are the results from differentiated analyses of students grouped by characteristics such as low initial self-efficacy, coding aversion, or less computer affinity. We found multiple significant effects of our courses to impact students of those groups positively. Our results clearly indicate the potential of interdisciplinary CSEd to address a more diverse audience, especially traditionally underrepresented groups
