Is Stem For All? Perspectives Of Black And Latino Students On Stem Motivation, Adrienne Coleman, Kayla Ingram '14 Jan 2015

Is Stem For All? Perspectives Of Black And Latino Students On Stem Motivation, Adrienne Coleman, Kayla Ingram '14

Publications & Research

Is Science, Technology, Engineering, and Mathematics (STEM) truly for all? According to the literature, it is rare to find gifted and talented Black and Latino Students who are engaged in STEM (C. G. Wright, 2011; LSA, 2005; Scott, 2010; Speight & Weatherspoon, 2009). They are virtually invisible in these majors and careers. While Caucasians and Asians view STEM careers as a world of opportunities, Blacks and Latinos see them as challenging and inaccessible (The Center on Education and Work, 2008). This results from a lack of exposure to STEM in K - 12 education, mathematics phobias, students’ misperceptions of what …


Technology Education For High-Ability Students, Carl Heine, James Gerry, Laurie S. Sutherland Jan 2015

Technology Education For High-Ability Students, Carl Heine, James Gerry, Laurie S. Sutherland

Publications & Research

Technologically adept teens not only consume technology voraciously; they create it. Gifted and talented students are attracted to technology for its capacity to transform learners from “receptacles of knowledge to active producers who direct their own learning” (Siegle, n.d.). Beyond the capacity to produce or innovate with technology is the opportunity to conceive and produce innovative technologies, a distinct type of tech giftedness (Siegle, n.d.) and the focus of the present chapter.

Technologically skilled teens have been doing this for some time, typically unassisted. It’s not hard to locate the connections between Facebook, Google, and YouTube and their gifted creators. …

Success After Failure: An Examination Of Credit Recovery Options And Their Effect On College- And Career-Readiness, Kathryn B. Johnson Jan 2015

Success After Failure: An Examination Of Credit Recovery Options And Their Effect On College- And Career-Readiness, Kathryn B. Johnson

Theses and Dissertations--Science, Technology, Engineering, and Mathematics (STEM) Education

More than ever before, educators and researchers are keeping a keen eye on student college- and career-readiness. The widely adopted Common Core State Standards were written with the explicit goal of helping students to be college- or career-ready by the time they graduate from high school. However, many students experience setbacks, such as course failure, within their educational career placing them at risk for not reaching this goal. Because the ACT can predict student success in college, states often use benchmark scores from the exam to measure student college- and career-readiness. A student who fails to learn fundamental concepts in …

Restructuring High School Science Curriculum: A Program Evaluation, Cathy Robertson

Walden Dissertations and Doctoral Studies

One rural Midwestern high school discovered a discrepancy among school, state, and national science skill attainment, verified by ACT scores. If students do not acquire vital science skills, they may not perform proficiently on science tests, thus impacting future college options. Inquiry based instruction and constructivism provided the basis for the theoretical framework. This study questioned associations between ACT scores, inquiry science technique usage, and ACT standard usage (Phase 1), and teachers' views on science instruction (Phase 2). This sequential explanatory mixed methods program evaluation included 469 ACT scores, surveys sent to 9 science teachers, and 8 interviews. Phase 1 …


The Short Grit Scale: A Dimensionality Analysis, Caihong Li Jan 2015

The Short Grit Scale: A Dimensionality Analysis, Caihong Li

Theses and Dissertations--Educational, School, and Counseling Psychology

This study aimed to examine the internal structure, score reliability, scoring, and interpretation of the Short Grit Scale (Grit-S; Duckworth & Quinn, 2009) using a sample of engineering students (N = 610) from one large southeastern university located in the United States. Confirmatory factor analysis was used to compare four competing theoretical models: (a) a unidimensional model, (b) a two-factor model, (c) a second-order model, and (d) a bi-factor model. Given that researchers have used Grit-S as a single factor, a unidimensional model was examined. Two-factor and second-order models were considered based upon the work done by Duckworth, Peterson, …


Science Teaching Reform Through Professional Development: Teachers’ Use Of A Scientific Classroom Discourse Community Model, Elizabeth Lewis, Dale R. Baker, Brandon Helding Jan 2015

Science Teaching Reform Through Professional Development: Teachers’ Use Of A Scientific Classroom Discourse Community Model, Elizabeth Lewis, Dale R. Baker, Brandon Helding

Department of Teaching, Learning, and Teacher Education: Faculty Publications

This report outlines a two-year investigation into how secondary science teachers used professional development (PD) to build scientific classroom discourse communities (SCDCs). Observation data, teacher, student and school demographic information were used to build a hierarchical linear model. The length of time that teachers received PD was the exclusive predictor of change over time, while a schools’ percentage of low socioeconomic students predicted of how much PD was initially implemented. Prior to PD teachers expressed a desire to increase opportunities for students to engage in SCDCs, but found some aspects more challenging than others to implement. Generally, there were three …

Under-Represented Students' Engagement In Secondary Science Learning: A Non-Equivalent Control Group Design, Joy J. Vann-Hamilton Jan 2015

Under-Represented Students' Engagement In Secondary Science Learning: A Non-Equivalent Control Group Design, Joy J. Vann-Hamilton

Dissertations

Problem.

A significant segment of the U.S. population, under-represented students, is under-engaged or disengaged in secondary science education. International and national assessments and various research studies illuminate the problem and/or the disparity between students’ aspirations in science and the means they have to achieve them. To improve engagement and address inequities among these students, more contemporary and/or inclusive pedagogy is recommended. More specifically, multicultural science education has been suggested as a potential strategy for increased equity so that all learners have access to and are readily engaged in quality science education. While multicultural science education emphasizes the integration of students’ …

Warm-ups were independently completed at the start of class meetings and consisted of questions about content covered 1–10 days prior to each warm-up. Students received feedback on their answers each week. A series …


Teaching High School Biology Students To Coordinate Text And Diagrams: Relations With Transfer, Effort, And Spatial Skill, Bradley W. Bergey, Jennifer G. Cromley, Nora S. Newcombe Jan 2015

Teaching High School Biology Students To Coordinate Text And Diagrams: Relations With Transfer, Effort, And Spatial Skill, Bradley W. Bergey, Jennifer G. Cromley, Nora S. Newcombe

Publications and Research

There is growing evidence that targeted instruction can improve diagram comprehension, yet one of the skills identified in the diagram comprehension literature—coordinating multiple representations —has rarely been directly taught to students and tested as a classroom intervention. We created a Coordinating Multiple Representation (CMR) intervention that was an addition to an intervention focused on Conventions of Diagrams (COD) and tested their joint effects on diagram comprehension for near transfer (uninstructed biology diagrams), far transfer (uninstructed geology diagrams), and content learning (biology knowledge). The comparison group received instruction using a previously validated intervention that focused exclusively on COD. Participants were 9th–10th …


Population Genetic Structure Of Asclepias Tuberosa In Northwest Iowa: A Comparison Within And Between Remnant Prairies And Commercially Available Seed, Jeffrey T. Ploegstra, Brittany De Ruyter, Tony Jelsma Jan 2015

Population Genetic Structure Of Asclepias Tuberosa In Northwest Iowa: A Comparison Within And Between Remnant Prairies And Commercially Available Seed, Jeffrey T. Ploegstra, Brittany De Ruyter, Tony Jelsma

Journal of the Iowa Academy of Science: JIAS

Isolated in scattered remnants, less than 0.1% of Iowa’s original tallgrass prairie remains. The small populations remaining are at risk for reduced genetic diversity, inbreeding depression, and outbreeding depression. In light of these concerns, we used microsatellite analysis to assess the genetic structure of butterfly milkweed (Asclepias tuberosa) populations on prairie remnants in northwest Iowa. We compared remnant populations with a restoration population at Dordt College in Sioux Center, Iowa, and with an Oklahoma seed source. Microsatellites identified for use in common milkweed (Asclepias syriaca) had sufficient polymorphism information content (PIC) across the butterfly milkweed ( …


Comte’S Positivist Doctrine And Reform Of Secondary Science Education In Nineteenth-Century Brazil, Karl M. Lorenz Jan 2015

Comte’S Positivist Doctrine And Reform Of Secondary Science Education In Nineteenth-Century Brazil, Karl M. Lorenz

Education Faculty Publications

This paper discusses the influence of the Positivist Philosophy on the teaching of science in the National Gymnasium, formerly the College Pedro II, in Brazil. With the proclamation of the Republic in 1889 and the subsequent educational reform of Minister Benjamin Constant in 1890, the curriculum of the college, and in particular the teaching of the sciences, was profoundly affected by the positivist ideas of Comte. An analysis of the programs of scientific studies adopted in the Gymnasium from 1890 to 1900 demonstrates that these were organized in accordance with the hierarchy of abstraction of human knowledge proposed by Comtean …


Women Of Faith In Science: The Double Glass Ceiling, K. Y. Michael Jan 2015

Women Of Faith In Science: The Double Glass Ceiling, K. Y. Michael

Journal of Mathematics and Science: Collaborative Explorations

The majority of female pre-service elementary school teachers pursuing licensure is choosing English as their cognate rather than mathematics or science. The reason females are not choosing science as their cognate may be due to the fact that science has long been considered a masculine pursuit. To complicate the issue, pre-service female teachers of deep religious faith are further challenged to navigate the dichotomy of science and religion. As a result, women, and especially women of deep religious faith, are at risk of not participating in science studies. The author suggests that there is room in the science classroom for …


Analyzing The Gender Gap On An Entrance Exam For Mathematically Talented Students, J. Butterfield, H. Keynes, J. Rogness, J. Sukiennik Jan 2015

Analyzing The Gender Gap On An Entrance Exam For Mathematically Talented Students, J. Butterfield, H. Keynes, J. Rogness, J. Sukiennik

Journal of Mathematics and Science: Collaborative Explorations

We investigate the qualifying entrance exam for the University of Minnesota Talented Youth Mathematics Program (UMTYMP), a five-year accelerated program covering high school- and undergraduate-level mathematics. The exam is used to assess the computational, numerical reasoning, and geometric skills of hundreds of fifth-, sixth-, and seventh-grade students annually. It has accurately identified qualified students in past years, but female participants consistently have had lower overall scores. Based on our belief that they are equally well qualified, in 2011 we began an extensive investigation into the structure and content of the exam to determine the possible sources for these differences. After …
