Using Experiential Learning In Course Curriculum: The Case Of A Core Engineering Graphics Course, Martha Marie Snyder, Manuel Salinas, Molly J. Scanlon

CCE Faculty Proceedings, Presentations, Speeches and Lectures

This work-in-progress paper overviews how an experiential education program was established at a private, non-profit university in the southeast, describes the process for certifying experiential courses using a formal course review process and qualification rubric, and details the case of a freshman engineering graphics course.

Grounded in the early works of Dewey, Lewin, and Piaget, experiential learning theory has become increasingly popular in higher education. Experiential learning serves as a foundation for lifelong learning and the development of the whole self as a citizen, family member and human being (Kolb, 2015). Austin and Rust (2015) define experiential learning as “‘hands-on’ …

Database Streaming Compression On Memory-Limited Machines, Damon F. Bruccoleri

CCE Theses and Dissertations

Dynamic Huffman compression algorithms operate on data-streams with a bounded symbol list. With these algorithms, the complete list of symbols must be contained in main memory or secondary storage. A horizontal format transaction database that is streaming can have a very large item list. Many nodes tax both the processing hardware primary memory size, and the processing time to dynamically maintain the tree. This research investigated Huffman compression of a transaction-streaming database with a very large symbol list, where each item in the transaction database schema’s item list is a symbol to compress. The constraint of a large symbol list …

Using Web Conferencing Technology To Foster Inclusive Course Experiences For Deaf And Hard-Of-Hearing Students, Elissa Weeden

CCE Theses and Dissertations

An Investigation Of The Interaction Between Organizational Culture And Knowledge Sharing Through Socialization: A Multi-Level Perspective, Ali Baker

CCE Theses and Dissertations

Knowledge management (KM) has been determined by many researchers as one of the most important domains within the information systems (IS) field, and knowledge sharing (KS) has been identified as the most vital component of KM. Lack of KS within organizations has been approached from many perspectives. One perspective that has been outlined in recent studies is the organizational culture (OC) perspective, which examines the interaction between OC and KS behaviors. Although research has been conducted on OC and KS, the findings of recent studies have been contradictory. These conflicts were due to the different operationalization of KS. The purpose …

Metrics For Aspect Mining Visualization, Gisle J. Jorgensen

CCE Theses and Dissertations

Aspect oriented programming has over the last decade become the subject of intense research within the domain of software engineering. Aspect mining, which is concerned with identification of cross cutting concerns in legacy software, is an important part of this domain. Aspect refactoring takes the identified cross cutting concerns and converts these into new software constructs called aspects. Software that have been transformed using this process becomes more modularized and easier to comprehend and maintain. The first attempts at mining for aspects were dominated by manual searching and parsing through source code using simple tools. More sophisticated techniques have since …

Beyond Automated Assessment: Building Metacognitive Awareness In Novice Programmers In Cs1, James Prather

CCE Theses and Dissertations

The primary task of learning to program in introductory computer science courses (CS1) cognitively overloads novices and must be better supported. Several recent studies have attempted to address this problem by understanding the role of metacognitive awareness in novices learning programming. These studies have focused on teaching metacognitive awareness to students by helping them understand the six stages of learning so students can know where they are in the problem-solving process, but these approaches are not scalable. One way to address scalability is to implement features in an automated assessment tool (AAT) that build metacognitive awareness in novice programmers. Currently, …

A Knowledge Management System (Kms) Using A Storytelling-Based Approach To Collect Tacit Knowledge, Nicholas Shaw

CCE Theses and Dissertations

Since the 1990s, Knowledge Management Systems (KMS) have been largely unsuccessful in the collection of tacit knowledge. The process, whether through direct input by the holder of the tacit knowledge or through an intermediary such as the collection of tacit knowledge through interviews and videos, has not succeeded. Reasons encompass the organizational (such as culture of the organization), the technological (example: poor tools), and the individual (example: knowledge is power, i.e. where experts with rare knowledge results in knowledge hoarding instead of transfer). The purpose of this study was to demonstrate that tacit knowledge could be successfully and consistently collected …

Multidimensional Knowledge Flow Dynamics In Context, Lina Lo

CCE Theses and Dissertations

Knowledge is a sustainable advantage and knowledge assets can increase value with use. A snowball effect of knowledge advantage advocates effective knowledge management and fosters its continual growth as it flows. Knowledge, however, flows unevenly throughout an organization and the problem is that the fundamental dynamics of these flows are still not well characterized in theoretical and computational models. This study built on existing work—knowledge-flow theory, need knowledge generation, and the critical success factors for enterprise resource planning implementation—to examine the multidimensional knowledge-flow phenomenon in context, and used the case study methodology for knowledge-flow theory building. The research question was …

Semi-Informed Multi-Agent Patrol Strategies, Chad E. Hardin

CCE Theses and Dissertations

The adversarial multi-agent patrol problem is an active research topic with many real-world applications such as physical robots guarding an area and software agents protecting a computer network. In it, agents patrol a graph looking for so-called critical vertices that are subject to attack by adversaries. The agents are unaware of which vertices are subject to attack by adversaries and when they encounter such a vertex they attempt to protect it from being compromised (an adversary must occupy the vertex it targets a certain amount of time for the attack to succeed). Even though the terms adversary and attack are …

An Operational Management Competency Model For Online Education Administrators, Fanniel Demarks

CCE Theses and Dissertations
