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 …

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 …

Instructional Teacher Job Resources And Student Achievement In Mathematics., Amy Stokes-Levine

Electronic Theses and Dissertations

Research shows that teachers who are supported with job resources are more engaged regardless of the level of demands (Klusmann et al., 2008). Additionally, teachers who are engaged with their work are less likely to report their intention to leave the teaching profession (Klassen et al., 2012), which is particularly important for mathematics teachers who are in high demand (Sutcher, Darling-Hammond, & Carver-Thomas, 2016). Supporting employees with job resources is a commonly accepted practice in many professional fields (e.g., Christian, Garza, & Slaughter, 2011), yet is not a common practice in education (e.g., Bidwell, 2013; Gewertz, 2014; Layton, 2015; Rentner …

A Comparative Study Teaching Chemistry Using The 5e Learning Cycle And Traditional Teaching With A Large English Language Learner Population In A Middle School Setting, Cynthia Nicole Mcwright

Dissertations

For decades science educators and educational institutions have been concerned with the status of science content being taught in K-12 schools and the delivery of the content. Thus, educational reformers in the United States continue to strive to solve the problem on how to best teach science for optimal success in learning. The constructivist movement has been at the forefront of this effort. With mandatory testing nationwide and an increase in science, technology, engineering, and mathematics (STEM) jobs with little workforce to fulfill these needs, the question of what to teach and how to teach science remains a concern among …

Roman Domination In Complementary Prisms, Alawi I. Alhashim

Electronic Theses and Dissertations

The complementary prism GG of a graph G is formed from the disjoint union of G and its complement G by adding the edges of a perfect match- ing between the corresponding vertices of G and G. A Roman dominating function on a graph G = (V,E) is a labeling f : V(G) → {0,1,2} such that every vertex with label 0 is adjacent to a vertex with label 2. The Roman domination number γR(G) of G is the minimum f(V ) = Σv∈V f(v) over all such functions of G. We study the Roman domination number of complementary prisms. …

Answers To Common Misconceptions About Biological Evolution, Leah M. Abebe, Blake Bartels, Kaitlyn M. Caron, Adam M. Gleeson, Samuel N. Johnson, Tyler J. Kluza, Nicholas W. Knopik, Kristen N. Kramer, Masiel S. Maza, Kaitlyn A. Stava, Kaitlyn Sullivan, Jordan T. Trimble, Robert M. Zink

Papers in Evolution

“When you have an established scientific emergent truth, it is true whether or not you believe in it.” Neil deGrasse Tyson, Science in America. Very few people outside of a particular scientific discipline can actually say they understand it, because most do not have the training to “speak the language.” They are then not particularly bothered by its tenets and predictions. Of all the major branches of science, however, evolutionary biology is an exception to this generalization because even though people are not versed in the field, they sometimes have a negative, knee-jerk objection. This objection is often because they …

To What Extent Does A Relationship Exist Between Nonsupport And Support Students When They Are Grouped Homogeneously And Heterogeneously In The Student's Mathematics Course At Lee County High School, Karen Lynn Hancock

Theses and Dissertations

Societal concerns and revolving federal initiatives linked State assessment scores to accountability measures which determined school success. In Southwest Georgia, one rural high school manipulated student schedules and provided an additional support course for individuals demonstrating documented mathematical deficiencies. The researcher examined the impact of three different grouping practices on the student’s 2014-15 Georgia Milestone Analytic Geometry End-of-Course assessment. This State assessment served as the dependent variable and the student grouping practice served as the independent variable for this quasi-experimental design study. Student schedules were examined and the three groups investigated during this study included 1) a group of students …

Elementary Teachers' Participation In Edmodo As A Community Of Practice: A Phenomenology, Cynthia Reasoner

Doctoral Dissertations and Projects

The purpose of this phenomenological study was to describe the shared, lived experience of elementary teachers’ participation in Edmodo as a community of practice. The theoretical framework guiding this research included Lave and Wenger’s (1991) community of practice theory and Bandura’s social learning theory (1977, 1984) which explained how learning through participation and observation occurs among teachers involved in learning communities. Social constructivism (Bruner, 1996; Piaget, 1971; Vygotsky, 1978) and adult learning theories (Mezirow, 1991, 1995; Knowles, 1984) also provided understanding as to how adults learn and create knowledge. This study described the lived experience of 10 elementary teachers and …

The Importance Of Extracurricular Stem Activities For Students With Disabilities, Karin Fisher

Proceedings of the Interdisciplinary STEM Teaching & Learning Conference (Archived)

Students with disabilities are underrepresented in science, technology, engineering and mathematics (STEM) careers (National Science Foundation, 2015). The underrepresentation is a problem because the nation’s competitiveness depends on diverse individuals with STEM knowledge, skills, and abilities to drive innovation that will need to new products and economic growth (Business higher Education Forum/A Policy Brief, 2014; National Academies of Sciences, Engineering, and Medicine, 2016; National Science Board, 2016). The author discusses the importance of engaging students with disabilities in informal Science, Technology, Engineering, and Mathematics activities.

Using Primary Sources In Stem Education: An Example, Josh Pfiester

Proceedings of the Interdisciplinary STEM Teaching & Learning Conference (Archived)

Primary sources are original artifacts from the past that can used to understand an event or time period. They are customarily only thought of in the realm of historical thinking. That is unfortunate because they can also be considered in terms of scientific, economic, cultural, and mathematical thinking. While primary sources are increasingly taking more prominent roles in the social studies and history classrooms, they are still very rare in other disciplines. This paper describes how primary sources gathered from the Library of Congress were situated in a larger STEM lesson focusing on the challenges faced by WWI veteran amputees. …

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

Why Teach Science? Helping Teacher Candidates Frame Instructional Decision Making From Moral And Ethical Perspectives, Grinell Smith, Colette Rabin

Faculty Publications

This qualitative research project’s overarching goal was to explore ways to help primary grade teacher candidates (re)kindle a conception of teaching as a moral enterprise involving ethical choices and enactment of one’s values. In the context of a science methods course, we explored the research question: What happens to the commitments toward science instruction of pre-service elementary teachers when we help them view science instruction as an act of caring? Our findings suggest that for many, this approach helped students take a moral stance, articulate an ethical position regarding educational issues, and use these perspectives to inform decision-making at the …

Student-Created Test Sheets, Samuel Laderach

Honors Projects

Assessment plays a necessary role in the high school mathematics classroom, and testing is a major part of assessment. Students often struggle with mathematics tests and examinations due to math and test anxiety, a lack of student learning, and insufficient and inefficient student preparation. Practice tests, teacher-created review sheets, and student-created test sheets are ways in which teachers can help increase student performance, while ridding these detrimental factors. Student-created test sheets appear to be the most efficient strategy, and this research study examines the effects of their use in a high school mathematics classroom.

Exploring The Potential To Motivate High School Environmental Science Students With Environmental Justice: A Mixed Methods Approach, Elliott Karetny

Theses and Dissertations

The purpose of this mixed-methods, design-based study was to explore the potential for socioscientific issues framed by environmental to motivate high school environmental science students. The embedded design began and ended with a survey of student dispositions, and included interviews of particular students in an effort to capture views of general and personal dispositions. Statistical analyses uncovered a moralistic approach to environmental decision-making, and a positive outlook of the future, including the confidence to solve environmental problems. Students revealed an abstract notion of the environment that requires innovative approaches to teaching environmental science, and view scientists as essential change agents …

Experiences With Scala Across The College-Level Curriculum, Konstantin Läufer, George K. Thiruvathukal, Mark C. Lewis

Emerging Technologies Laboratory

Various hybrid-functional languages, designed to balance compile-time error detection, conciseness, and performance, have emerged. Scala, e.g., is interoperable with Java and has become an early leader in adoption, especially in the start-up and open-source spaces.

As educators, we have recognized Scala’s value as a teaching language across the CS curriculum. In CS1, the read-eval-print loop and simple, uniform syntax aid programming in the small. In CS2, higher-order methods allow concise, efficient manipulation of collections. In a programming languages course, advanced constructs facilitate the separation of concerns, program representation and interpretation, and concurrent programming. In advanced applied courses, language mechanisms and …

Claim, Evidence, And Reasoning: Evaluation Of The Use Of Scientific Inquiry To Support Argumentative Writing In The Middle School Science Classroom, Gabriela Mastro

Scholarly and Creative Works Conference (2015 - 2021)

In light of the essential science and engineering practices identified by the Next Generation Science Standards (NGSS), this study focuses on the specific science and engineering practice, "engage in argument from evidence," and how classroom practices can serve to strengthen this skill (National Research Council, 2012, p. 71). The NGSS focus on inquiry necessitates students’ use of argument, particularly in writing, to communicate their knowledge and scientific findings and to develop an understanding of scientific practice. The purpose of this teacher action research study is to evaluate the influence of inquiry-based argumentative writing exercises, based on the Argument Driven Inquiry …

Sixth Graders Investigate Models And Designs Through Teacher-Directed And Student-Centered Inquiry Lessons: Effects On Performance And Attitudes, Benjamin D. Olsen, Audrey C. Rule

Journal of STEM Arts, Crafts, and Constructions

Science inquiry has been found to be effective with students from diverse backgrounds and varied academic abilities. This study compared student learning, enjoyment, motivation, perceived understanding, and creativity during a science unit on Models and Designs for 38 sixth grade students (20 male, 18 female; 1 Black, 1 Hispanic and 36 White). The unit began with a very teacher-centered approach, then became increasingly student-centered, employing more inquiry with each lesson set to determine the effects of student-centered instruction on performance and attitudes. Pretest-posttest data with specific questions tied to each lesson set were collected, as well as repeated measures attitude …
