Evaluating the Integration of Online, Interactive Tutorials into a Data Structures and Algorithms CourseBreakiron, Daniel Aubrey 28 May 2013 (has links)
OpenDSA is a collection of open source tutorials for teaching data structures and algorithms. It was created with the goals of visualizing complex, abstract topics; increasing the amount of practice material available to students; and providing immediate feedback and incremental assessment. In this thesis, I first describe aspects of the OpenDSA architecture relevant to collecting user interaction data. I then present an analysis of the interaction log data gathered from three classes during Spring 2013. The analysis focuses on determining the time distribution of student activity, determining the time required for assignment completion, and exploring \credit-seeking" behaviors and behavior related to non-required exercises.
We identified clusters of students based on when they completed exercises, verified the reliability of estimated time requirements for exercises, provided evidence that a majority of students do not read the text, discovered a measurement that could be used to identify exercises that require additional development, and found evidence that students complete exercises after obtaining credit. Furthermore, we determined that slideshow usage was fairly high (even when credit was not ordered), and skipping to the end of slideshows was more common when credit was offered but also occurred when it was not. / Master of Science

VText: A Plug-in Extension to Add Electronic Textbook Functionality to Microsoft OneNoteCristy, John Oliver 27 January 2014 (has links)
Electronic textbooks are different from ebooks (electronic books) in that they allow the user to go beyond just reading material on a computer screen. Electronic textbooks encourage the user to accomplish all of the operations typically performed with a hardcopy text in addition to some functions not possible with paper books. With electronic textbooks users can make annotations in the textbook with e-ink; mark important sections; search over the ink, the text, or even the scanned images; look up items in online dictionaries or encyclopedias; perform interactive reinforcement drills; view simulations; and many other operations afforded by the computing power of the underlying computer and the reach of the Internet connection. These operations encourage students to engage in active reading.
The VText framework is designed to provide many of the desired features of an e-textbook in such a way that it produces pedagogical value rather than just convenience for students. Many so-called e-textbook solutions available today provide few features beyond those possible with hardcopy textbooks. The VText framework is built as an add-in to Microsoft's note-taking program, OneNote. The add-in provides features that facilitate the use of OneNote as a reader and as an educational tool while leaving in place OneNote's strengths in note-taking, collaboration, and search. / Master of Science

Interactive Visualization for Novice LearnersChon, Jieun 09 July 2019 (has links)
Iteration, the repetition of computational steps, is a core concept in programming. Students usually learn about iteration in an entry-level Computer Science class. Virginia Tech's Computational Thinking (CT) course is designed to teach non-CS majors computing skills and new ways of thinking. The course covers iteration on Day 8 of the class. We conducted a pretest before, and three post-tests after, Day 8 of the Computational Thinking class in Spring 2018 on 137 students. The pre-test was intended to measure knowledge of iteration before the material was covered. We found from the post-tests that students' knowledge of iteration did not satisfy the course objectives in Spring 2018, because the knowledge gain shown between pre-test and post-tests was not significant. We developed interactive visualizations and exercises for Fall 2018 and Spring 2019. For three semesters we conducted tests and compared the data from Fall 2018 and Spring 2019 (the treatment) against Spring 2018 (the control). We found that Spring 2019 students had greater knowledge gains than Spring 2018 students. Also, we conducted surveys in Fall 2018 and Spring 2019 from students to learn more about their recall, helpfulness, and reuse of the interactive visualizations. Finally, we analyzed data from the interactive exercises and page use to investigate students' usage behavior. / Master of Science / Iteration is a process of repeating a set of instructions or structures.

We found from the post-tests that students’ knowledge of iteration did not satisfy the course objectives in Spring 2018. In particular, the knowledge gain shown between pre-test and post-tests was not significant. We developed interactive visualizations and exercises that were used during Fall 2018 and Spring 2019. We conducted tests and compared the data from Fall 2018 and Spring 2019 (the treatment) against Spring 2018 (the control). To see if there was a statistically significant difference between the absolute score means of three groups, we used independent sample t-tests. Also we used paired sample t-tests to see if there was a greater knowledge gain after using our invention. By analyzing the results of the t-tests, we found that Spring 2019 students had greater knowledge gains than Spring 2018 students. Also, we conducted student surveys in Fall 2018 and Spring 2019 to learn more about their opinions on recall, helpfulness, and reuse of the interactive visualizations. We analyzed data from the interactive exercises and page use to investigate students’ usage behavior.

Analyzing Student Session Data in an eTextbookHeo, Samnyeong 18 July 2022 (has links)
As more students interact with online learning platforms and eTextbooks, they generate massive amounts of data. For example, the OpenDSA eTextbook system collects clickstream data as users interact with prose, visualizations, and interactive auto-graded exercises. Ideally, instructors and system developers can harness this information to create better instructional experiences. But in its raw event-level form, it is difficult for developers or instructors to understand student behaviors, or to make testable hypotheses about relationships between behavior and performance.
In this study, we describe our efforts to break raw event-level data first into sessions (a continuous series of work by a student) and then to meaningfully abstract the events into higher-level descriptions of that session. The goal of this abstraction is to help instructors and researchers gain insights into the students' learning behaviors. For example, we can distinguish when students read material and then attempt the associated exercise, versus going straight to the exercise and then hunting for the answers in the associated material.
We first bundle events into related activities, such as the events associated with stepping through a given visualization, or with working a given exercise. Each such group of events defines a state. A state is a basic unit that characterizes the interaction log data, and there are multiple state types including reading prose, interacting with visual contents, and solving exercises. We harnessed the abstracted data to analyze studying behavior and compared it with course performance based on GPA. We analyzed data from the Fall 2020 and Spring 2021 sections of a senior-level Formal Languages course, and also from the Fall 2020 and Spring 2021 sections of a data structures course. / Master of Science / OpenDSA is an online learning platform used in multiple academic institutions including Virginia Tech's Computer Science courses. They use OpenDSA as the main instructional method and students in these courses generate massive amounts of clickstream data while interacting with the OpenDSA content. The system collects various events logs such as when students opened/closed a certain page, how long they stayed on the page, and how many times they clicked an interface element for visualizations and exercises. However, in its raw event-level form, it is difficult for instructors or developers to understand student behaviors, or to make testable hypotheses about relationships between behavior and performance. We describe our efforts to break raw event-level clickstreams into a session (continuous series of work by a student) and then to abstract the events into meaningful higher-level descriptions of students' behavior. We grouped raw events into related activities, such as the events associated with stepping through a given visualization, or working with a given exercise.
We defined such a group of activities as a state, which is a basic unit that can characterize the interaction log data such as reading, slideshows, and exercises state. We harnessed the abstracted data to analyze students' studying behavior and compared it with their course performance based on their GPA. We analyzed data from two offerings of two CS courses at Virginia Tech to gain insights into students' learning behaviors.

Elektronické knihy a jejich uplatnění v českém vysokém školství / Electronic books and their use in Czech higher education systemBarvíková, Martina January 2012 (has links)
The goal of the thesis is to formulate suggestion to Czech universities regarding publication of textbooks and academic texts in electronic formats. The thesis also provides a general view of the Czech ebook market -- the history, formats and digital right management of ebooks are described. The process of ebook elaboration and reading devices with their pros and cons are also mentioned. The comparison of world and Czech ebook and etextbook market is emphasized and the availability of Czech etextbooks and academic text in Czech higher education institutions is mapped. The hypothesis that Czech students' demand for etextbooks is sufficient for profitable etextbook elaboration by Czech higher education institutions in the way that prevents from illegal sharing of content and violating of authorial laws is examined.
