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

Dissertations & Theses in Natural Resources

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 ...


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

Heteroglossic Practices In A Multilingual Science Classroom, Lydiah Kananu Kiramba

Faculty Publications: Department of Teaching, Learning and Teacher Education

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 ...


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

DBER 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

DBER 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 ...


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

DBER 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

DBER 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

Dissertations & Theses in Natural Resources

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 this ...


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

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

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 beliefs of two ...

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

Dissertations & Theses in Natural Resources

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 ...


Successful Female Students In Undergraduate Computer Science And Computer Engineering: Motivation, Self-Regulation, And Qualitative Characteristics, Melissa Patterson Hazley Apr 2016

Successful Female Students In Undergraduate Computer Science And Computer Engineering: Motivation, Self-Regulation, And Qualitative Characteristics, Melissa Patterson Hazley

Public Access Theses and Dissertations from the College of Education and Human Sciences

Computer Science (CS) and Computer Engineering (CE) fields typically have not been successful at recruiting or retaining women students. Research indicates several reasons for this shortage but mainly from three perspectives: social issues, exposure/prior knowledge and curriculum issues in K-12 settings. This mixed-methods research addresses a gap in the literature by investigating the motivation and self-regulation behaviors of successful female students who are studying computer science and computer engineering. The findings in phase one of this study indicated that learning and performance approach goals predicted adaptive strategic self-regulation behaviors including strategy use, knowledge building and engagement. Learning avoidance goals ...

Put Away Your Phone And Learn! How Technology Engages Or Disengages Students And… When It Is Good That Your Students Are Confused, Douglas K. Duncan

DBER Speaker Series

Some technology increases student learning, some decreases it. I will show evidence of both and discuss what makes the difference. Approximately 70% of college students now text during class, and no faculty member we studied saw even as much as half of the texting that occurred. Is there any viable way to stop this? What should instructors do about the use of laptops in class?

The second part of the talk will address the uses of confusion, presenting interesting data showing the type of confusion that leads to increased student learning. Part of the discussion will be how demos – beloved ...


Concepts About Sedimentology And Stratigraphy In Undergraduate Geoscience Courses, Bailey Z. Kreager Apr 2016

Concepts About Sedimentology And Stratigraphy In Undergraduate Geoscience Courses, Bailey Z. Kreager

Dissertations & Theses in Earth and Atmospheric Sciences

This two-part study examines sedimentologic and stratigraphic concepts in undergraduate geoscience courses. The first part seeks to identify the various types of interactive engagement strategies used in undergraduate science courses, how they are used and in what fields. It also looks at areas in which the geosciences have excelled in interactive engagement strategies. Published studies describing interactive engagement strategies in college-level courses were collected and coded, which identified six emergent types of interactive engagement strategies: (1) Polling, (2) Full-Class Discussion and Activities, (3) In-Class Group Work, (4) Out-Of-Class Group Work, (5) Online Work, and (6) Other types. Interactive engagement strategies ...

Building Exemplary Teaching Practices: Following The Paths Of New Science Teachers, Elizabeth B. Lewis, Ana Rivero, Aaron A. Musson, Jia Lu, Lyrica Lucas

Talks and Presentations: Department of Teaching, Learning and Teacher Education

There are few comprehensive studies of beginning science teachers that describe enacted teaching practices in terms of inquiry-based instruction, classroom discourse, assessment, and curricular choices, and explore how these factors interact with teaching self-efficacy. We conducted a 3-year, longitudinal study of four cohorts of master’s level science teacher education program graduates. We coded and analyzed 319 science lessons of new teachers from student teaching to third year post-program to describe teachers’ enacted practices and gathered annual teaching self-efficacy reports to examine teachers’ beliefs. Our analysis resulted in key findings relevant to future programmatic improvements. First, when we reviewed specific ...


The Scientific Teaching Practices Survey For Undergraduate Stem Courses, Mary F. Durham, Jenny K. Knight, Brian Couch Apr 2016

The Scientific Teaching Practices Survey For Undergraduate Stem Courses, Mary F. Durham, Jenny K. Knight, Brian Couch

DBER Speaker Series

The National Academies Summer Institutes on Undergraduate Education (SI) is a faculty development workshop in which STEM instructors are trained in the Scientific Teaching (ST) pedagogy and encouraged to implement its practices at their home institutions. While participants generally report positive experiences at the SI, it remains unclear how these experiences affect instructors’ teaching practices and associated student outcomes. As part of a larger effort to evaluate the SI, we developed a survey to gauge the frequencies of ST practices that could occur in undergraduate STEM courses. The ST Practices Survey is derived from the observable teaching practices described in ...


Assessing Student Comprehension In Introductory Biology: A Comparison Of Free-Response And Multiple-True/False Exam Formats, Macy A. Potts, Brian Couch, Joanna K. Hubbard Apr 2016

Assessing Student Comprehension In Introductory Biology: A Comparison Of Free-Response And Multiple-True/False Exam Formats, Macy A. Potts, Brian Couch, Joanna K. Hubbard

UCARE Research Products

Question format is an important consideration when designing instruments to gauge student comprehension. In many lecture-style courses, instructors must decide how to effectively test a large group of students. Two common types of question formats used for introductory biology exams are free-response (FR) and multiple-true/false (MTF). FR questions include a question prompt which students respond to with essay-style answers. Conversely, MTF questions include an opening question stem with accompanying statements to be marked as either true or false. The goal of this study was to determine the advantages and disadvantages of FR and MTF question formats for assessing student ...

DBER Speaker Series

This study analyzed the role of the evidence-based instructional practice of Just-in-time (JIT) teaching integrated with the flipped classroom in an undergraduate biological systems engineering course. In the present paper we provide a detailed overview of the course design, development, and implementation of JIT in a flipped approach to instruction by communicating the technologies used, pedagogy employed to integrate online and in-class activities, and the collaboration between the instructional design support and instructor. Based on the results, we provide recommendations for engineering faculty that want to explore the flipped approach to teaching, examples for online learning activities and how to ...


Using Interactive Engagement Strategies To Enhance Learning In College Science Courses, Bailey Z. Kreager, Leilani Arthurs Apr 2016

Using Interactive Engagement Strategies To Enhance Learning In College Science Courses, Bailey Z. Kreager, Leilani Arthurs

DBER Speaker Series

The number of decreasing science majors in U.S. institutions of higher education is connected to the quality of science instruction (Seymour, 1994; Daempfle, 2003) and resulted in nation-wide efforts to improve the quality of college-level science education (National Committee on Science Education Standards and Assessment et al., 1996; NGSS Lead States, 2013). This talk presents historical trends in the adoption of interactive engagement (IE) strategies in college-level science courses and presents one such IE strategy, lecture tutorials (LTs), in the context of sedimentology and stratigraphy.

To determine historical trends in the adoption of IE strategies, peer-reviewed journal articles accessible ...

Computational Modeling Intervention: Using Dynamical Models To Teach Complex Biological Processes, Audrey J. Crowther, Tomáš Helikar, Nicholas Galt, Joseph Dauer, Heather Berganr, Bryan Kowal

UCARE Research Products

The Unites States, while being one of the richest countries in the world, ranks 17th in science proficiency out of 31 countries. New techniques for teaching are needed if the US wants to keep up with increasing global competition. Often the problem with traditional methods for teaching biological processes is that they present the material as linear or causal, when in fact there is a much wider network at play. For example, cellular respiration is often represented as a linear process that always starts with glucose and always ends with ATP and water. However, there are several entry and exit ...


Probing Question Order Effect In Chemistry Concept Inventories, Molly Undersander, Travis J. Lund, Laurie S. Langdon, Marilyne Stains Apr 2016

Probing Question Order Effect In Chemistry Concept Inventories, Molly Undersander, Travis J. Lund, Laurie S. Langdon, Marilyne Stains

UCARE Research Products

The design of assessment tools is critical to evaluate accurately students’ understanding of chemistry. Although extensive research has been conducted on various aspects of assessment tool design, few studies in chemistry have focused on the impact of the order in which questions are presented to students on the measurement of students’ understanding and students’ performance. This potential impact has been labeled the question order effect in other literature. The set of studies described in this article tested whether question order effects were present within a concept inventory on acid-based chemistry. In particular, we tested whether the order of two conceptually ...

Remember Embers: Model-Based Reasoning, Collaborative Teams And Much More!, David Gosselin Mar 2016

Remember Embers: Model-Based Reasoning, Collaborative Teams And Much More!, David Gosselin

DBER Speaker Series

Studies of interdisciplinary research teams indicate that team members struggle to achieve knowledge integration across disciplines. Knowledge integration across disciplines is at the heart of addressing important research challenges, such as impacts of global change, trade-offs between water, food, and energy production, and the need for sustainable cities. The EMBeRS Project is testing a new model for integrating knowledge across disciplines based on cognitive science theories of model-based reasoning. The project will create educational materials to train students to overcome the barriers to integrating knowledge across disciplines.

Issues arise due to the inability of team members to work collaboratively in ...


Enriching Student’S Online Homework Experience In Pre-Calculus Courses: Hints And Cognitive Supports, Nathan Wakefield Mar 2016

Enriching Student’S Online Homework Experience In Pre-Calculus Courses: Hints And Cognitive Supports, Nathan Wakefield

DBER Speaker Series

As part of reforming our Pre-Calculus courses we realized that reforms to instruction needed to be accompanied by reforms to the homework. Homework is completed online using an open-source homework system. In this study we investigated and implemented a new means of providing our students more support on missed questions. Utilizing a new WebWorK “hints” feature and leveraging our network of experienced high-school teachers we developed leading questions and helps to prompt student thinking over procedures. Preliminary data shows many students are using these hints and the hints are working as intended. In this presentation I will discuss the development ...
