Regression Diagnostics: Identifying Influential Data and Sources of Collinearity

Recent advances in technology and in ideology have unlocked entirely new directions for education research. Mounting pressure from increasing tuition costs and free, online course offerings is opening discussion and catalyzing change in the physical classroom. The flipped classroom is at the center of this discussion. The flipped classroom is a new pedagogical method, which employs asynchronous video lectures and practice problems as homework, and active, group-based problem solving activities in the classroom. It represents a unique combination of learning theories once thought to be incompatible—active, problem-based learning activities founded upon a constructivist ideology and instructional lectures derived from direct instruction methods founded upon behaviorist principles. This paper provides a comprehensive survey of prior and ongoing research of the flipped classroom. Studies are characterized on several dimensions. Among others, these include the type of in-class and out-of-class activities, the measures used to evaluate the study, and methodological characteristics for each study. Results of this survey show that most studies conducted to date explore student perceptions and use single-group study designs. Reports of student perceptions of the flipped classroom are somewhat mixed, but are generally positive overall. Students tend to prefer in-person lectures to video lectures, but prefer interactive classroom activities over lectures. Anecdotal evidence suggests that student learning is improved for the flipped compared to traditional classroom. However, there is very little work investigating student learning outcomes objectively. We recommend for future work studies investigating of objective learning outcomes using controlled experimental or quasi-experimental designs. We also recommend that researchers carefully consider the theoretical framework used to guide the design of in-class activities. 1 The Rise of the Flipped Classroom There are two related movements that are combining to change the face of education. The first of these is a technological movement. This technological movement has enabled the amplification and duplication of information at an extremely low-cost. It started with the printing press in the 1400s, and has continued at an ever-increasing rate. The electronic telegraph came in the 1830s, wireless radio in the late 1800s and early 1900s, television in the 1920s, computers in the 1940s, the internet in the 1960s, and the world-wide web in the 1990s. As these technologies have been adopted, the ideas that have been spread through their channels have enabled a second movement. Whereas the technological movement sought to overcome real physical barriers to the free and open flow of information, this ideological movement seeks to remove the artificial, man-made barriers. This is epitomized in the free software movement (see, e.g., Stallman and Lessig [67]), although this movement is certainly not limited to software. A good example of this can be seen from the encyclopedia. Encyclopedia Britannica has been P ge 23200.2 continuously published for nearly 250 years [20] (since 1768). Although Encyclopedia Britannica content has existed digitally since 1981, it was not until the advent of Wikipedia in 2001 that open access to encyclopedic content became available to users worldwide. Access to Encyclopedia Britannica remains restricted to a limited number of paid subscribers [21], but access to Wikipedia is open, and the website receives over 2.7 billion US monthly page views [81]. Thus, although the technology and digital content was available to enable free access to encyclopedic content, ideological roadblocks prevented this from happening. It was not until these ideologies had been overcome that humanity was empowered to create what has become the world’s largest, most up-to-date encyclopedia [81]. In a similar way, we are beginning to see the combined effects of these two movements on higher education. In the technological arena, research has made significant advances. Studies show that video lectures (slightly) outperform in-person lectures [9], with interactive online videos doing even better (Effect size=0.5) [83,51]. Online homework is just as effective as paper-and-pencil homework [8,27], and carefully developed intelligent tutoring systems have been shown to be just as effective as human tutors [77]. Despite these advancements, adoption has been slow, as the development of good educational systems can be prohibitively expensive. However, the corresponding ideological movement is breaking down these financial barriers. Ideologically, MIT took a significant step forward when it announced its OpenCourseWare (OCW) initiative in 2001 [53]. This opened access to information that had previously only been available to students who paid university tuition, which is over $40,000/yr at MIT [54]. Continuing this trend, MIT alum Salman Khan founded the Khan Academy in 2006, which has released a library of over 3200 videos and 350 practice exercises 2012. The stated mission of the Khan Academy is to provide “a free world-class education to anyone anywhere2012.” In the past year, this movement has rapidly gained momentum. Inspired by Khan’s efforts, Stanford professors Sebastian Thrun and Andrew Ng opened access to their online courses in Fall 2011. Thrun taught artificial intelligence with Peter Norvig, attracting over 160,000 students to their free online course. Subsequently, Thrun left the university and founded Udacity, which is now hosting 11 free courses [76]. With support from Stanford, Ng also started his own open online educational initiative, Coursera. Princeton, the University of Pennsylvania, and the University of Michigan have joined the Coursera partnership, which has expanded its offerings to 42 courses [10]. MIT has also upgraded its open educational initiative, and joined with Harvard in a $60 million dollar venture, edX [19]. EdX will, “offer Harvard and MIT classes online for free.” While online education is improving, expanding, and becoming openly available for free, university tuition at brick-and-mortar schools is rapidly rising [56]. Tuition in the University of California system has nearly tripled since 2000 [32]. Naturally, this is not being received well by university students in California [2]. Likewise, students in Quebec are actively protesting planned tuition hikes [13]. In resistance to planned tuition hikes, student protestors at Rutgers interrupted (on June 20, 2012) a board meeting to make their voices heard [36]. Adding fuel to the fire, results from a recent study by Gillen et al. [31] indicate that undergraduate student tuition is used to subsidize research. As a result, the natural question being asked by both students and educational institutions is exactly what students are getting for their money. This is applying a certain pressure on physical academic institutions to improve and enhance the in-person educational experience of their P ge 23200.3

The flipped classroom: A survey of the research

There is increasing pressure for Higher Education institutions to undergo transformation, with education being seen as needing to adapt in ways that meet the conceptual needs of our time. Reflecting this is the rise of the flipped or inverted classroom. The purpose of this scoping review was to provide a comprehensive overview of relevant research regarding the emergence of the flipped classroom and the links to pedagogy and educational outcomes, identifying any gaps in the literature which could inform future design and evaluation. The scoping review is underpinned by the five-stage framework Arksey and O'Malley. The results indicate that there is much indirect evidence emerging of improved academic performance and student and staff satisfaction with the flipped approach but a paucity of conclusive evidence that it contributes to building lifelong learning and other 21st Century skills in under-graduate education and post-graduate education.

The use of flipped classrooms in higher education: A scoping review

Recent technological developments have given rise to blended learning classrooms. An inverted (or flipped) classroom is a specific type of blended learning design that uses technology to move lectures outside the classroom and uses learning activities to move practice with concepts inside the classroom. This article compares the learning environments of an inverted introductory statistics class with a traditional introductory statistics class at the same university. This mixed-methods research study used the College and University Classroom Environment Inventory (CUCEI), field notes, interviews and focus groups to investigate the learning environments of these two classrooms. Students in the inverted classroom were less satisfied with how the classroom structure oriented them to the learning tasks in the course, but they became more open to cooperative learning and innovative teaching methods. These findings are discussed in terms of how they contribute to the stability and connectedness of classroom learning communities.

How Learning in an Inverted Classroom Influences Cooperation, Innovation and Task Orientation.

Flipped classroom approaches remove the traditional transmissive lecture and replace it with active in-class tasks and pre-/post-class work. Despite the popularity of these approaches in the media, Google search, and casual hallway chats, there is very little evidence of effectiveness or consistency in understanding what a flipped classroom actually is. Although the flipped terminology is new, some of the approaches being labelled ‘flipped’ are actually much older. In this paper, we provide a catch-all definition for the flipped classroom, and attempt to retrofit it with a pedagogical rationale, which we articulate through six testable propositions. These propositions provide a potential agenda for research about flipped approaches and form the structure of our investigation. We construct a theoretical argument that flipped approaches might improve student motivation and help manage cognitive load. We conclude with a call for more specific types of research into the effectiveness of the flipped classroom ...

The Internet and the Inverted Classroom

Purpose – Customers have high expectations that company representatives contacted online will go out of their way to be helpful. One type of social media that may be particularly useful as a customer relationship management (CRM) tool is microblogging platforms such as Twitter. The purpose of this paper is to look at the impact of perceived helpfulness of customer representative microblog responses on people's perceptions of brand trust, brand benevolence, brand attitudes and intentions to try or purchase a brand.Design/methodology/approach – A field experiment was conducted to manipulate three variables: type of helpfulness response (empathetic or problem‐solving), amount of helpfulness (less or more helpful), and interface in which responses were viewed (branded, Google, or Twitter).Findings – The interaction between type of helpfulness and amount of helpfulness led to greater perceptions of company trustworthiness and benevolence when there were many problem‐solving responses than when there were few, ...

“I'm here to help”: How companies' microblog responses to consumer problems influence brand perceptions

This paper explores the factors influencing the adoption of state lotteries in the United States. The conceptual framework utilizes a common utility framework in which a representative legislator maximizes utility derived from the current and expected fiscal position of a state, subject to a political constraint. The empirical results support the theoretical hypotheses, including the finding that changes in the fiscal health of the state, the predicted profit potential of a lottery, and the political climate of the state all affect the likelihood that a lottery is adopted. By introducing a sound conceptual framework, using better data than used in previous studies, utilizing an appropriate estimation technique, and obtaining strong results, this study advances our knowledge of why states adopt lotteries.
