Where Science Intersects Pop Culture: An Informal Science Education Outreach Program, Raychelle Burks, Kiyomi D. Deards, Erica Defrain Jan 2017

Where Science Intersects Pop Culture: An Informal Science Education Outreach Program, Raychelle Burks, Kiyomi D. Deards, Erica Defrain

University of Nebraska-Lincoln Libraries: Faculty Publications

Attracting a general audience to STEM topics can be a challenge, and developing engaging and interactive instruction is important for educators in all fields. While many chemical educators have successfully used pop-culture themes to introduce their students to scientific concepts, these encounters are largely limited to formal classroom environments. Inspired by the successes of community science programs such as Science Café and Nerd Nite, science educators from two Nebraska campuses sought to broaden the exposure of their pop-culture themed class lectures, and created the SciPop Talks! program. Now entering its fifth year, this informal educational outreach program has become a …


Student Buy-In Toward Formative Assessments: The Influence Of Student Factors And Importance For Course Success, Kathleen R. Brazeal, Brian A. Couch Jan 2017

Student Buy-In Toward Formative Assessments: The Influence Of Student Factors And Importance For Course Success, Kathleen R. Brazeal, Brian A. Couch

School of Biological Sciences: Faculty Publications

Formative assessment (FA) techniques, such as pre-class assignments, in-class activities, and post-class homework, have been shown to improve student learning. While many students find these techniques beneficial, some students may not understand how they support learning or may resist their implementation. Improving our understanding of FA buy-in has important implications, since buy-in can potentially affect whether students fully engage with and learn from FAs. We investigated FAs in 12 undergraduate biology courses to understand which student characteristics influenced buy-in toward FAs and whether FA buy-in predicted course success. We administered a mid-semester survey that probed student perceptions toward several different …


First-Year And Non-First-Year Student Expectations Regarding In-Class And Out-Of-Class Learning Activities In Introductory Biology, Tanya L. Brown, Brian A. Couch Jan 2017

First-Year And Non-First-Year Student Expectations Regarding In-Class And Out-Of-Class Learning Activities In Introductory Biology, Tanya L. Brown, Brian A. Couch

School of Biological Sciences: Faculty Publications

National calls for teaching transformation build on a constructivist learning theory and propose that students learn by actively engaging in course activities and interacting with other students. While interactive pedagogies can improve learning, they also have the potential to challenge traditional norms regarding class participation and learning strategies. To better understand the potential openness of students to interactive teaching practices, we administered a survey during the first week of two sections of an introductory biology course to characterize how students envisioned spending time during class as well as what activities they expected to complete outside of class during non-exam weeks …


Measurement Instrument For Scientific Teaching (Mist): A Tool To Measure The Frequencies Of Research-Based Teaching Practices In Undergraduate Science Courses, Mary F. Durham, Jennifer K. Knight, Brian A. Couch Jan 2017

Measurement Instrument For Scientific Teaching (Mist): A Tool To Measure The Frequencies Of Research-Based Teaching Practices In Undergraduate Science Courses, Mary F. Durham, Jennifer K. Knight, Brian A. Couch

School of Biological Sciences: Faculty Publications

The Scientific Teaching (ST) pedagogical framework provides various approaches for science instructors to teach in a way that more closely emulates how science is practiced by actively and inclusively engaging students in their own learning and by making instructional decisions based on student performance data. Fully understanding the impact of ST requires having mechanisms to quantify its implementation. While many useful instruments exist to document teaching practices, these instruments only partially align with the range of practices specified by ST, as described in a recently published taxonomy. Here, we describe the development, validation, and implementation of the Measurement Instrument for …

Heteroglossic Practices In A Multilingual Science Classroom, Lydiah Kananu Kiramba Dec 2016

Heteroglossic Practices In A Multilingual Science Classroom, Lydiah Kananu Kiramba

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

This paper uses sociocultural theories of language learning to investigate how teachers and students navigate between monolingual institutional policies and the multilingual realities encountered in a rural Kenyan fourth-grade classroom. The paper addresses not only how learners’ communicative repertoires are deployed to make meaning in a foreign language instruction context but also the sociocultural significance of these communicative practices. Results illustrate how the science teacher used heteroglossic practices to mediate students’ access to literacy, hence, supporting the content learning and language development of students. Both the science teacher and the students preferred a more flexible use of language to make …

Exploration Of Student Biodiversity Knowledge And Decision-Making For A Wildlife Conservation Socioscientific Issue, Ashley R. Alred Dec 2016

Exploration Of Student Biodiversity Knowledge And Decision-Making For A Wildlife Conservation Socioscientific Issue, Ashley R. Alred

School of Natural Resources: Dissertations, Theses, and Student Research

Global biodiversity, a foundation for ecosystem function, is diminishing at a rate unprecedented in the last 50 years. Biodiversity loss and ecosystem services deterioration is linked to increased food insecurity, reduced water quality and availability, decreased energy security, higher economic losses and human suffering (Millennium Ecosystem Assessment, 2005). Consequently, educators should invest in supporting students in their development of ecological understanding and formal decision-making skills so they are equipped with meaningful tools they can use as scientifically literate citizens. To contribute to that mission, this study seeks to explore student 1) comprehension and explanation of biodiversity concepts and 2) decision-making …


Collegiate Active Learning Calculus Survey (Calcs): Adapting An Instrument And Using Results, Wendy M. Smith Oct 2016

Collegiate Active Learning Calculus Survey (Calcs): Adapting An Instrument And Using Results, Wendy M. Smith

Discipline-Based Education Research Group Speaker Series

When we make changes to a course, we want to know if they "worked." There is often a desire to broaden the definition of success beyond student (passing) grades. We know from research that the further students go in mathematics, their attitudes toward and beliefs about mathematics get more and more negative. Thus, if we slow or even reverse that trend, we might then claim success for our reform efforts. Research teams at the University of Colorado Boulder created the CLASS: Colorado Learning Attitudes about Science Survey; this was originally designed for undergraduate physics, then later adapted for use with …


Benefits Of Using R For Dber, Jordan Harshman Oct 2016

Benefits Of Using R For Dber, Jordan Harshman

Discipline-Based Education Research Group Speaker Series

When carrying out quantitative discipline based educational research projects, researchers have a variety of choices when it comes to which statistical package s/he chooses to use. In this presentation, I will convey how one programming language, R, has not only provided an abundance of advantages, but has transformed the way I see data analysis. R is a free program with thousands of add-in packages capable of doing a majority of basic and advanced statistical techniques and graphics. By investigating a hypothetical data set through cluster analysis, I will present how 1) defining custom functions efficiently allows for iterative exploratory investigations, …


Clicker Use In Introductory Biology: Impacts On Exam Performance, Joanna K. Hubbard Oct 2016

Clicker Use In Introductory Biology: Impacts On Exam Performance, Joanna K. Hubbard

Discipline-Based Education Research Group Speaker Series

In-class response systems, or clickers, are useful formative assessment tools that support learning by providing real-time feedback that can be used to correct misconceptions through peer discussion and instructor guidance. Previous research has shown that peer discussion improves conceptual understanding within a class period. In this study, we asked whether the benefits of peer discussion could be detected on a longer time scale. We asked exam questions that were isomorphic to in-class clicker questions and found students that participated in peer discussion scored higher than students that were not in class for the discussion. We also examined the effect of …

Spatial Skills & Introductory Computing, Steve Cooper Sep 2016

Spatial Skills & Introductory Computing, Steve Cooper

Discipline-Based Education Research Group Speaker Series

Our questions

Is there a correlation between a student's spatial abilities and her ability in programming? Spatial abilities are measured through the R-PSVT, and CS programming ability is measured the 2009 AP CS MC questions

If yes, can we increase programming success through the teaching of spatial skills?

Results

Spatial training seemed to be correlated with better CS gains, and in particular helped Hispanic women and students from low SES backgrounds

Caveats

We measured code reading, but taught code writing

Differing student demographics for the 2 sessions

Instructional Framing And Student Learning Of Community Interactions, Nathaniel Niosco Jul 2016

Instructional Framing And Student Learning Of Community Interactions, Nathaniel Niosco

School of Natural Resources: Dissertations, Theses, and Student Research

Ecology is a broad field of science that encompasses many disciplines with large impacts in our society (AAAS, 2011; NRC, 2009). To understand the complex systems and concepts of this discipline requires a foundation of knowledge that students often gain in the classroom (Bransford, Brown, & Cocking, 2000). Helping students develop this foundation of knowledge requires an understanding of how they use surface and deep reasoning skills to understand and learn new material. In addition, using methods to teach students to transfer these skills between multiple contexts is key to expanding their ability to broadly apply knowledge. The purpose of …


A Reformed College Algebra Course: Understanding Instructors' And Students' Beliefs About Teaching And Learning Mathematics, Mary Williams Jun 2016

A Reformed College Algebra Course: Understanding Instructors' And Students' Beliefs About Teaching And Learning Mathematics, Mary Williams

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

Reforms of undergraduate mathematics (e.g. Bressoud & Rasmussen, 2015; Laursen et. al, 2011) are changing the practice of teaching and learning within their courses. Prior research has established strong connections between practices and beliefs (Brickhouse, 1990; Raymond, 1997; Aguirre & Speer, 1999), therefore changing the practices within these courses may be affecting the beliefs of those tasked to enact the reformed practices. Thus, part of the work of the reforms in undergraduate mathematics is to learn how and why these beliefs may or may not be changing in this culture of reform.

In this qualitative case study, I analyzed the …

Exploring Elementary Students’ Agricultural And Scientific Knowledge Using Evidence Centered Design, Molly R. Brandt May 2016

Exploring Elementary Students’ Agricultural And Scientific Knowledge Using Evidence Centered Design, Molly R. Brandt

School of Natural Resources: Dissertations, Theses, and Student Research

The public is more disconnected from agriculture than ever. Americans are two to four generations removed from the farm, and a majority of Americans, even in rural agricultural states have no direct link to agriculture. As a result, the public lacks the knowledge and appreciation of the food, fuel, and fiber it demands. The National Center for Agricultural Literacy (NCAL) uses National Agricultural Learning Objectives (NALOs) to measure student’s agricultural knowledge. The purpose of this project is to develop assessments aligned with the NALOs and to use results from the assessments to further understand students’ agricultural literacy. This study focuses …
