Using Two Simulation Tools To Teach Concepts In Introductory Astronomy: A Design-Based Research Approach, Pamela A. Maher

UNLV Theses, Dissertations, Professional Papers, and Capstones

Technology in college classrooms has gone from being an enhancement to the learning experience to being something expected by both instructors and students. This design-based research investigation takes technology one step further, putting the tools used to teach directly in the hands of students. The study examined the affordances and constraints of two simulation tools for use in introductory astronomy courses. The variety of experiences participants had using two tools; a virtual reality headset and fulldome immersive planetarium simulation, to manipulate a lunar surface flyby were identified using a multi-method research approach with N = 67 participants. Participants were recruited …

A Study Of Strengthening Secondary Mathematics Teachers’ Knowledge Of Statistics And Probability Via Professional Development, Lina Devaul

UNLV Theses, Dissertations, Professional Papers, and Capstones

A professional development program (PSPD) was implemented to improve in-service secondary mathematics teachers’ content knowledge, pedagogical knowledge, and self-efficacy in teaching secondary school statistics and probability. Participants generated a teaching resource website at the conclusion of the PSPD program. Participants’ content knowledge change and self-efficacy change were measured. After PSPD, three participants were selected to represent three types of change. Teachers’ classroom instructions were video-taped and analyzed to explore the enactment of PSPD components, such as activities and concepts. Interviews were conducted to assess factors that facilitated teachers’ change and the enactment of PSPD components. Preservice teachers who majored in …

Using Mobile Technology To Increase The Math Achievement And Engagement Of Students With Disabilities, Dominique Marie Tetzlaff

UNLV Theses, Dissertations, Professional Papers, and Capstones

The advent of advanced technologies provides new opportunities for delivering instruction to students with disabilities. Many classrooms have access to mobile devices, such as iPads and Kindles, and educators utilize these devices to differentiate instruction and augment teacher-led instruction. This delivery method, known as blended learning, can create an enriched learning environment where students are exposed to individualized lessons that are self-paced and provide multiple modes of presentation. However, there is little empirical investigation into how students interact with digital devices or what components of online learning directly impact student learning and engagement with the content. In order to design …

Are Universities Providing Non-Stem Students The Mathematics Preparation Required By Their Programs?: A Case Study Of A Quantitative Literacy Pathway And Vertical Alignment From Remediation To Degree Completion, Charles Merritt Allen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Informed by Gagne's belief in the necessity of prerequisite knowledge for new learning, and Bruner's Spiral Curriculum Theory, the objective of this case study was to explore the postsecondary pathway from remedial mathematics, through one gateway mathematics course, and into the quantitative literacy requirements of various non-STEM programs of study. Particular attention was directed towards analyses of the vertical alignment of course content between: (1) the two consecutive remedial mathematics courses (Beginning Algebra and Intermediate Algebra), (2) the two remedial courses and the gateway course (Fundamentals of College Mathematics), and (3) the gateway course and the quantitative literacy needs of …

Instructional Math Technology In Secondary Special Education: Teacher-Reported Practices And Perceptions, Joice M. Higa

UNLV Theses, Dissertations, Professional Papers, and Capstones

Students with disabilities often have difficulty meeting established math proficiency levels. Without these skills, students may face increased challenges in transitioning to adulthood, including fewer post-secondary educational opportunities, limited career options, and decreased long-term income. Addressing low math skills is important to improving options for students with disabilities. Research indicates that technology-based interventions have the potential to improve academic outcomes.

The purpose of this study was to examine the math instructional technology used in secondary math classrooms with students with disabilities. The study also examined teacherperceived barriers and desired supports related to the integration of technology. A three-round Delphi method …

Examining The Affordances Of Dual Cognitive Processing To Explain The Development Of High School Students’ Nature Of Science Views, Luke Jackson

UNLV Theses, Dissertations, Professional Papers, and Capstones

This mixed method study was aimed at examining the influence of dual processing (Type 1 and Type 2 thinking) on the development of high school students’ nature of science (NOS) views. Type 1 thinking is intuitive, experiential, and heuristic. Type 2 thinking is rational, analytical, and explicit. Three research questions were asked: (1) Do the experiential process (Type 1) and the logical process (Type 2) influence the development of students’ NOS views? (2) If there is an influence on students’ NOS views, then what is the nature of relationship between the experiential process (Type 1) and the development of NOS …

Effectiveness Of St Math In College Remedial Mathematics Students Of Learning Fraction Concepts, Taro Ito

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examined the extent to which the iPad app, Spatial Temporal Mathematics (ST Math), diminished college remedial mathematics students’ natural number bias and deepened their fraction conceptual understanding. In this quasi-experimental study one class played the ST Math fraction games for 8 weeks, and they were compared to a control class who were taught without technology. The frameworks for this study included the framework theory of conceptual change, the reorganization theory, the microworld and the Lesh Translation Model. Pre and post- tests were used to examine the fraction conceptual understanding of the students in the ST Math class and …
