Engaging Underrepresented High School students in Data Driven Storytelling: An Examination of Learning Experiences and Outcomes for a Cohort of Rising Seniors Enrolled in the Gaining Early Awareness and Readiness for Undergraduate Program (GEAR UP)

Background: Upward trends in data-oriented careers threaten to further increase the underrepresentation of both females and individuals from racial minority groups in programs focused on data analysis and applied statistics. To begin to develop the necessary skills for a data-oriented career, project-based learning seems the most promising given its focus on real-world activities that are aimed at engaging student interest and enthusiasm. Method: Using pre and post survey data, the present study examines student background characteristics, learning experiences and course outcomes for a cohort of 33 rising high school seniors involved in a two-week, accelerated version of a project-based data analysis and applied statistics curriculum. Results: On average, students rated the experience as rewarding and the vast majority (78.1%) felt that they had accomplished more than they had expected. Based on responses to both the pre and post course surveys, roughly half of the students reported increases in confidence in applied skills (i.e. developing a research question, managing data, choosing the correct statistical test, effectively presenting research results, and conducting a statistical analysis of data), while more than 80% reported increased confidence in writing code to run statistical analyses. Fully 84.4% of students reported interest in one or more follow-up courses with interest in computer programming being endorsed by the largest number of students (53.1%). Conclusions: These findings support previous research showing that real-world, project-based experiences afford the best hope for achieving the kind of analytic and statistical literacy necessary for meaningful engagement in research, problem solving and professional development

Perceptions of Scratch Programming among Secondary School Students in KwaZulu-Natal, South Africa

Scratch programming was designed with the aim of helping students to develop their logical thinking skills as well as enhancing their problem-solving capabilities, without having the technical distractions associated with more advanced programming languages such as Java. This study, guided by the technology acceptance model (TAM), focused on exploring the associations between perceived usefulness, perceived ease of use, attitude towards use, and behavioural intention to use the Scratch programming language, with the aim of identifying how Scratch programming was perceived by a group of South African students in Grades 10 and 11 at two high schools. Results indicated, among other things, that Grade 10 students perceived Scratch to be easy to use and useful, and Grade 11 students found it to be easy to use but useful only in learning introductory programming concepts. These and other findings suggest that while Scratch helps students understand logic and problem-solving, it does not assist sufficiently in preparing them for using a higher-level programming language such as Java. The article concludes with recommendations for South African education policymakers, including proposals that a bridging programming language be introduced between Scratch and Java, and that Scratch be introduced much earlier than in Grade 10.CA201

Linguistic diversity and the politics of international inclusion in higher education: A critical sociolinguistic study international teaching assistants

Institutions of higher education (HEIs) in the United States recruit numerous international graduate students, many of whom serve as teaching assistants. HEIs’ motivations for employing international teaching assistants (ITAs) include not only economic incentives but also humanistic aims of internationalization, for example, increasing cross-cultural cooperation. However, integrating ITAs into the institution, making them welcomed and respected members of the community, has proven difficult. In particular, problems in ITA-student communication have been reported for decades. I argue that the crux of these integration difficulties lies in how linguistic diversity is approached. Policymakers and researchers usually treat ITAs’ Englishes as the cause of communication difficulties, with the implication that ITAs should more closely conform to norms of ‘native’ English. I propose instead that the primary problem is not linguistic diversity itself but ideological perceptions of other Englishes and unproductive responses to the difficulties that arise in trying to communicate across linguistic difference. This study examined policies and perceptions related to ITA-student communication at one internationalizing university through document collection, interviews, and classroom observation. I found that, despite its strategic plan calling for preparing students to enter a globalizing world, the institution’s response to ITA-student communication difficulties targets only ITAs’ competencies, mainly by assessing and remediating their language proficiency. Discussions with students and observations of classroom interaction revealed that many students appeared to orient to communication with ITAs in ways that did not help promote successful communication or prepare them to communicate across linguistic difference in a globalizing world. I also found that available ideological stances and strategies for addressing linguistic difference made it difficult for ITAs to be simultaneously liked and respected as instructors. This study has implications for HEIs seeking to create internationally inclusive communities and prepare their students and other stakeholders for communication across linguistic difference. First, ITA preparation should be reframed so as not to stigmatize ITAs’ Englishes. It should also prepare ITAs to become active agents in socializing students into productive and respectful orientations to linguistic difference. Second, HEIs must more comprehensively seek to confront students’ deficit language ideologies and unproductive responses to communication difficulties

Applying science of learning in education: Infusing psychological science into the curriculum

The field of specialization known as the science of learning is not, in fact, one field. Science of learning is a term that serves as an umbrella for many lines of research, theory, and application. A term with an even wider reach is Learning Sciences (Sawyer, 2006). The present book represents a sliver, albeit a substantial one, of the scholarship on the science of learning and its application in educational settings (Science of Instruction, Mayer 2011). Although much, but not all, of what is presented in this book is focused on learning in college and university settings, teachers of all academic levels may find the recommendations made by chapter authors of service. The overarching theme of this book is on the interplay between the science of learning, the science of instruction, and the science of assessment (Mayer, 2011). The science of learning is a systematic and empirical approach to understanding how people learn. More formally, Mayer (2011) defined the science of learning as the “scientific study of how people learn” (p. 3). The science of instruction (Mayer 2011), informed in part by the science of learning, is also on display throughout the book. Mayer defined the science of instruction as the “scientific study of how to help people learn” (p. 3). Finally, the assessment of student learning (e.g., learning, remembering, transferring knowledge) during and after instruction helps us determine the effectiveness of our instructional methods. Mayer defined the science of assessment as the “scientific study of how to determine what people know” (p.3). Most of the research and applications presented in this book are completed within a science of learning framework. Researchers first conducted research to understand how people learn in certain controlled contexts (i.e., in the laboratory) and then they, or others, began to consider how these understandings could be applied in educational settings. Work on the cognitive load theory of learning, which is discussed in depth in several chapters of this book (e.g., Chew; Lee and Kalyuga; Mayer; Renkl), provides an excellent example that documents how science of learning has led to valuable work on the science of instruction. Most of the work described in this book is based on theory and research in cognitive psychology. We might have selected other topics (and, thus, other authors) that have their research base in behavior analysis, computational modeling and computer science, neuroscience, etc. We made the selections we did because the work of our authors ties together nicely and seemed to us to have direct applicability in academic settings

Preparatory Physics for Scientists and Engineers: An Interactive Course Supplement based on the Assessment of the Initial Conditions of Physics Experience

There are several factors that contribute to the low success rates of introductory, calculus-based physics courses. A significant factor is prior experience. The Physics Experience Survey instrument that measures a student‘s prior experience learning physics will be discussed. A student is classified as either a novice learner, continuing learner, or experienced learner based on their responses to questions about prior coursework and confidence with specific physics topics. Administration of this survey to 123 students is an attempt to identify novice physics learners in calculus-based introductory physics courses who might benefit from a low-cost, 7-week (14 total contact hours) course supplement emphasizing fundamental skills and topics. Correlations between experience level and final course grade, first exam grade, and learner level are discussed. The course supplement and its impact on novice physics learners‘ conceptual understanding (as measured by the Force Concept Inventory) and problem solving skills (as measured by the Problem Solving Assessment) is described

All Advanced Placement (AP) Computer Science is Not Created Equal: A Comparison of AP Computer Science A and Computer Science Principles

This article compares the two most prominent courses of Advanced Placement (AP) computer science study offered throughout 9-12 grades in the U.S. The structure, guidelines, components, and exam formats of the traditional AP Computer Science A course and the relatively newer AP Computer Science Principles course were compared to examine differences in content and emphases. A depth-of-learning analysis was conducted employing Bloom’s Revised Taxonomy to examine potential differences in rigor and challenge represented by the two options, particularly as it relates to acquiring computer programming proficiency. Analyses suggest structural differences in both course content and end-of-course exam components likely result in less depth and rigor in the new Computer Science Principles course as compared to the Computer Science A course. A lower minimum standard for learning programming skills in the Computer Science Principles course was observed, making it a less viable option for students looking to acquire skills transferable to future computer science study or employment. The potential implications for students choosing the new course over the traditional offering, as well as for schools opting for the new course as its sole or primary offering are discussed

Three Essays on the Impact of Cost-saving Strategies on Student Outcomes

For two decades, state financing of higher education has been on the decline and the situation has exacerbated since the onset of the economic recession, where the US state systems have resorted to a substantial cut of funding for higher education. Faced with the challenges of limited resources for financial pressure and an increasing demand, community colleges either have taken or are considering taking a series of cost-saving strategies. Some of the most prominent trends seen in the past decades include sharp expansions in distance education offerings through online coursework, an increasing reliance on part-time adjunct faculty, and a heated discussion about slashing expenditures on remedial education. Yet, many researchers argue that these strategies might be implemented at the cost of poorer educational quality and less desirable student outcomes. My dissertation assesses the impacts of several important strategies that community colleges are engaged in an era of financial constraints on student academic outcomes and educational equality. In Chapter One, Shanna Smith Jaggars and I examine the fast growth of distance education and its impacts on student outcomes relative to traditional face-to-face delivery format. Based on a large administrative data set from Washington State, we found robust negative estimates for online learning in terms of both course persistence and course grade. While all types of students in the study suffered decrements in performance in online courses, we also identified strong variations across subpopulations and academic subject areas. Chapter Two is prompted by the spiraling increase in part-time faculty hiring in open-access two-year community colleges. Based data from a large community college system, I identified a positive impact of taking one's first course in a subject area on his contemporaneous course performance but negative impacts on subsequent course outcomes and enrollment patterns. Finally, Chapter Three is inspired by the heated debate related to the effectiveness of college remediation. Exploiting discontinuities in students' probability of receiving remediation both around the college-level cut off and the cut off for short versus long sequence of remediation, I found small and insignificant impacts of remediation for students on the margin of needing remediation, but significantly negative influence on students receiving long sequence of remediation compared to those who received short sequence. These results suggest that some cost-saving strategies that colleges are recently engaged may bring negative impacts on student learning outcomes, and therefore policymakers and college administrators may need to take steps to ensure the quality of education offered to students before enacting policies that would incentivize an accelerated expansion of online enrollments, and overreliance on adjunct instructors. Additionally, the insignificant and negative impact of remediation suggests that the huge investment in remediation may not have been effectively utilized to serve its purpose and colleges will need to explore ways to improve its effectiveness

The Perceived Undergraduate Classroom Experiences of African-American Women in Science, Technology, Engineering, and Mathematics (STEM)

The purpose of this dissertation study was to explore African-American women's perceptions of undergraduate STEM classroom experiences, and the ways in which those experiences have supported or hindered their persistence in physics majors. The major research question guiding this study was: How do African-American women perceive the climate and interactions with peers and faculty in undergraduate STEM classrooms? Using qualitative methods and a multiple case study design, a sample of 11 women were interviewed. This study was also informed by data from 31 African-American women who participated in focus group interviews at annual meetings of the National Society of Black and Hispanic Physicists. Findings indicated that the women excelled in small courses with faculty who took a personal interest in their success. They also perceived that there was a pervasive culture in physics and other STEM departments that often conflicted with their own worldviews. Findings also indicated that the women's perceptions of classroom experiences varied widely depending on professors' behaviors, institution types, and the level of courses. It is anticipated that through a better understanding of their perceptions of STEM learning environments and factors in their persistence, STEM faculty and departments can better retain and support this population of students
