Grassroots Or Returning To One’S Roots? Unpacking The Inception Of A Youth-Focused Community Makerspace, Victor R. Lee, Whitney L. King, Ryan Cain

Instructional Technology and Learning Sciences Faculty Publications

In this paper, we describe the individuals and factors contributing to the emergence of a community makerspace in a small city in the United States. As research into how makerspaces have come into existence is still in a nascent stage, this single case study is intended to describe and highlight some of the complexities involved in creating such a facility. Based on analysis of onsite observations, interviews of adults connected with the space, and electronic communications, we present a story of how two co-founders of a youth-focused makerspace went from having initial interest in extracurricular activities for their own children …

The Effects Of A Varied Method Of Instruction On Student Achievement, Transfer, Situational Interest, And Course Retention Rates In Community College Developmental Mathematics, Kevin L. Mccandless

Doctoral Dissertations

The purpose of this quasi-experimental study was to compare the effects of a varied method of instruction on student achievement, knowledge transfer, situational interest, and course retention rates, relative to a non-varied method of instruction, in community college developmental mathematics. The varied method of instruction consisted of active learning teaching practices with foundations in social constructivism, whereas the non-varied method of instruction was founded in Cognitive Load Theory and consisted primarily of explicit instruction and individual practice.

An initial sample of 139 students who enrolled in six sections of Beginning Algebra at an urban community college in Northern California participated …

An Investigation Of Tree Biomass In The Great Smoky Mountains National Park, Curt Skipper, Patrick Stokley, Sherry S. Herron

Faculty Publications

We determined the biomass (carbon storage) of four forest types in the Great Smokey Mountains National Park; pine/oak, cove hardwood, northern hardwood, and spruce/fir. Based on the GLOBE Programs land cover protocols (www.globe.gov), and the University of New Hampshire's GLOBE Carbon Cycle Program (http;//globecarboncycle.unh.edu/), we knew that species and tree circumference would be the two most critical factors in determining biomass, but we also hypothesized that number of trees in a study site and the elevation of the site would impact biomass. We hypothesized that old growth forest would contain greater biomass than a young forest. …

The Development And Tryout Of A Program Designed To Increase Students' Multiplication Fact Fluency, Linton D. Williams

PCOM Psychology Dissertations

Fluency skills are fundamental to the ability to complete relatively more complex problems using less mental energy. Most math curriculums do not stress the importance of automaticity of math facts. Variations in teaching styles and teaching modality seem to negate the true purpose for cementing and rapidly retrieving math facts. This study put to the test a program that was designed to increase students’ ability to retrieve multiplication facts fluently. The program exercised cognitive structures and enabled students to retrieve multiplication facts quickly. The results of a matched-pairs t-test indicated that after the students completed the course of the program, …

Understanding Angle And Angle Measure: A Design-Based Research Study Using Context Aware Ubiquitous Learning, Helen Crompton

Teaching & Learning Faculty Publications

Mobile technologies are quickly becoming tools found in the educational environment. The researchers in this study use a form of mobile learning to support students in learning about angle concepts. Design-based research is used in this study to develop an empirically-substantiated local instruction theory about students' develop of angle and angle measure. This local instruction theory involves real-world connections and mobile technologies through a sub category of mobile learning called context-aware ubiquitous learning. Through a process of anticipation, enactment, evaluation, and revision, the local instruction theory was developed to include a theoretical contribution of how students come to understand angle …

High School Students' And Scientists' Perceptions Of A Student-Scientist Partnership, Karla Singh

Open Access Theses & Dissertations

The idea of getting high school students to work with scientists has become a hot topic. There have been many programs that get students involved with scientists to gain experience. Having students work with scientists allows students to practice authentic science. These programs also aim to get more students interested in science and hopefully inspire these students to go into a science career.

Challenges In Assessing College Students' Conception Of Duality: The Case Of Infinity, Grace Olutayo Babarinsa-Ochiedike

Open Access Theses & Dissertations

Interpreting students' views of infinity posits a challenge for researchers due to the dynamic nature of the conception. There is diversity and variation among students' process-object perceptions. The fluctuations between studentsâ?? views however reveal an undeveloped duality conception. This study examined college students' conception of duality in understanding and representing infinity with the intent to design strategies that could guide researchers in categorizing students' views of infinity into different levels.

Data for the study were collected from N=238 college students enrolled in Calculus sequence courses (Pre-Calculus, Calculus I through Calculus III) at one of the southwestern universities in the U.S. …

Gender Differences In College Students’ Perceptions Of Technology-Related Jobs In Computer Science, Joseph Appianing, Richard Van Eck

Teaching, Leadership & Professional Practice Faculty Publications

Demand for computer technology (CT) professionals continues to rise, yet the supply of related majors is insufficient to meet demand. As with science, engineering, and mathematics (technology’s STEM field siblings), women’s participation in CT fields is abysmally low. While there are many junctures in the “leaky pipeline” for women and STEM careers, college is one of the important pathways to recruit women into CT fields. Wigfield and Eccles’ (2000) expectancy-value theory of achievement motivation provides a valuable framework for examining factors that impact women’s decisions to pursue CT majors, but no validated survey instruments exist for doing so. A questionnaire …
