Improvement Of Pedagogical Laboratory Based Learning: Multimedia Enhanced Instructional Methods, Sumbul Khan

Masters Theses & Specialist Projects

In engineering technology and other scientific-based education, lab-based courses play a crucial role (Ma & Nickerson, 2006). Even though laboratory experience in student learning is crucial, it faces some problems. Due to insufficient laboratory conditions that lead to overcrowding and inability to view demonstrations, the effectiveness of hands on experience declines (Tiwari & Singh, 2011; Tuysuz, 2010). Considering the limitations that constrain lab experience, investigating and implementing alternatives to enhance pedagogical laboratory based learning becomes inevitable. This study investigates multimedia enhanced pedagogical teaching methods for delivering laboratory instruction to students. The purpose of this study was to improve pedagogical laboratory …

Gendered Socialization With An Embodied Agent: Creating A Social And Affable Mathematics Learning Environment For Middle-Grade Females, Yanghee Kim, J. Lim

Yanghee Kim

This study examined whether or not embodied-agent-based learning would help middle-grade females have more positive mathematics learning experiences. The study used an explanatory mixed-methods research design. First, a classroom-based experiment was conducted with one hundred and twenty 9th-graders learning introductory algebra (53% male and 47% female; 51% Caucasian and 49% Latino). The results revealed that learner gender was a significant factor in the learners’ evaluations of their agent (η2 = .07), the learners’ task-specific attitudes (η2 = .05), and their task-specific self-efficacy (η2 = .06). In-depth interviews were then conducted with 22 students selected from the experiment participants. The interviews …

Online Resource Aiding Students To Practice And Perfect Manufacturing Based Skills, Robert Martin Morris, Frank Dunne, Maurice Collins

Conference papers

As part of our teaching in the Departments of Fabrication and Transport Engineering in the Technological University Dublin we use industrial metal folding machines to help students to learn the sequencing of folds on manufactured sheet metal components. Many students have difficulty visualising the folding sequences required to complete practical manufacturing assignments. This paper details the digital media resource which was developed to provide students with the opportunity to offer a proposed solution to questions which relate to the folding sequence required for these components. Feedback is provided through the medium of pre recorded videos which show the component being …

Digital Peers To Help Children's Text Comprehension And Perception, Yanghee Kim

Yanghee Kim

Affable Reading Tutor (ART) is an online reading lesson designed for children who start reading to comprehend. A digital, human-like character (virtual peer) in ART serves as a peer model that demonstrates the use of the reading comprehension strategy questioning to help improve the learners’ comprehension of expository texts. This study, with 141 boys and girls in the fourth and fifth grades in the United States, examined the effects of virtual-peer presence (presence vs. absence vs. control) on learners’ text comprehension and also the effects of learner gender and virtual-peer attributes (human-like male vs. human-like female vs. robot still image) …

An Exploration Of Social Media Use Among Multiply Minoritized Lgbtq Youth, Alfie Leanna Lucero

Open Access Theses & Dissertations

This study responds to a need for research in a fast-growing and significant area of study, that of exploring, understanding, and documenting the numerous ways that multiply marginalized LGBTQ youth between the ages of 14 and 17 use social media. The primary research question examined whether social media provide safe spaces for multiply minoritized LGBTQ youth to express and explore issues of sexuality and gender. In addition, the study explores and categorizes multiple ways that the participants interact with social media and makes comparisons to prior work with more general populations. The study provides descriptions of the participants in terms …

Examining The Effects Of Computational Tools On Students' Conceptual Understanding Of Thermodynamics Of Material Concepts And Representations, Oyindamola Oluwatimi

Open Access Theses

Technology is becoming a more critical agent for supporting learning as well as research in science and engineering. In particular, technology-based tools in the form of simulations and virtual environments support learning using mathematical models and computational methods. The purpose of this research is to: (a) measure the value added in conveying Thermodynamics of materials concepts with a blended learning environment using computational simulation tools with lectures; and (b) characterize students' use of representational forms to convey their conceptual understanding of core concepts within a learning environment that blended Gibbs computational resource and traditional lectures.

A mix-method approach was implemented …

Development Of Novel Nano-Composite Membranes As Introduction Systems For Mass Spectrometers: Contrasting Nano-Composite Membranes And Conventional Inlet Systems, Luis Miranda

USF Tampa Graduate Theses and Dissertations

This dissertation presents the development of novel nano-composite membranes as introduction systems for mass spectrometers. These nano-composite membranes incorporate anodic aluminum oxide (AAO) membranes as templates that can be used by themselves or modified by a variety of chemical deposition processes. Two types of nano-composite membranes are presented. The first nano-composite membrane has carbon deposited within the pores of an AAO membrane. The second nano-composite membrane is made by coating an AAO membrane with a thin polymer film. The following chapters describe the transmission properties these nano-composite membranes and compare them to conventional mass spectrometry introduction systems. The nano- composite …
