The “Tri” in their name refers to the three parts of their foundation: giving a third of their yield to volunteers, giving a third to local food pantries, and selling a third to sustain the farm and demonstrate the economy of local food production. They want to expand on the third part and have a vision of building a hydroponic greenhouse with the intention that it will create more crops to sell and give, as well as …

Introducing Science Education In Early Childhood, Marissa M. Arciniega

Capstone Projects and Master's Theses

The increasing focus on literacy development and kindergarten readiness in preschool has created a lack of science education in early childhood education. In recent research, Head Start found that of the four academic readiness domains for preschoolers (i.e., language, literacy, math, and science), science is the lowest-performing area amongst students in their program (Bustamante, White, & Greenfield, 2018). Research is showing that declining performance in science is partly due to the lack of science education in classrooms. Lack of science is not only affecting school performance down the road, but it also limits children in receiving the benefits of early …

Addressing Diversity And Inclusion Through Group Comparisons: A Primer On Measurement Invariance Testing, Guizella A. Rocabado, Regis Komperda, Jennifer E. Lewis, Jack Barbera

Chemistry Faculty Publications and Presentations

As the field of chemistry education moves toward greater inclusion and increased participation by underrepresented minorities, standards for investigating the differential impacts and outcomes of learning environments have to be considered. While quantitative methods may not be capable of generating the in-depth nuances of qualitative methods, they can provide meaningful insights when applied at the group level. Thus, when we conduct quantitative studies in which we aim to learn about the similarities or differences of groups within the same learning environment, we must raise our standards of measurement and safeguard against threats to the validity of inferences that might favor …

Exploring Pedagogical Empathy Of Mathematics Graduate Student Instructors, Karina Uhing

Department of Mathematics: Dissertations, Theses, and Student Research

Interpersonal relationships are central to the teaching and learning of mathematics. One way that teachers relate to their students is by empathizing with them. In this study, I examined the phenomenon of pedagogical empathy, which is defined as empathy that influences teaching practices. Specifically, I studied how mathematics graduate student instructors conceptualize pedagogical empathy and analyzed how pedagogical empathy might influence their teaching decisions. To address my research questions, I designed a qualitative phenomenological study in which I conducted observations and interviews with 11 mathematics graduate student instructors who were teaching precalculus courses at the University of Nebraska—Lincoln.

In the …

Designing Stem Experiences For The Family In Order To Develop Stem Family Habitus And Capital, Soñia Galaviz

Boise State University Theses and Dissertations

Ethnic minority students and low-income students are grossly underrepresented in demonstrating interest and aspirations in science, evidence of science participation, and subsequent capital. Members of these populations do not often embrace a STEM identity or recognize that science, technology, engineering, and math are for them. While schools struggle to innovate in terms of how best to engage and increase aspirations and opportunities in STEM for these underrepresented populations, the family continues to be the most ignored contributor to a student’s STEM identity. Families play an important role in influencing their students’ attitudes, interests, aspirations, and achievements in STEM. While research …

An Investigation Of The Impacts Of Traditional, Virtual, And Hybrid Biological Laboratories On College Students’ Achievement And Motivation To Learn Biology, Shavonda Jackson

Dissertations

Virtual courses function in a different manner than traditional courses, therefore they require teaching methods and assessment techniques geared specifically to maximize this learning experience. Internet-based learning and distance-education are no longer new concepts in the science field. Because of this, many collegiate biology programs have created courses that can be taken virtual or hybrid. A number of experimental studies have had great influence in terms of the effects and impacts of educational technology in relation to virtual laboratories.

However, not many studies emphasize the impact of hybrid laboratories on student achievement or assess students’ motivation to learn in a …

The Marshmallow Lab: A Project-Based Approach To Understanding Functional Responses, Melissa Pulley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper presents a three-part lesson plan to improve student’s understanding of Holling’s type II functional response model. This model describes the interaction between a predator and how much it is able to consume given a constant number of prey. According to the model, while increased availability of prey allows predators to consume portionately more prey for low values, after some number of prey, predators will only be able to capture a limited number of prey even as the prey continues to increase. This phenomenon is known as saturation. Holling first develop this important ecological theory through his “disc experiment” …

Measuring Meaningful Learning In A Chemistry Laboratory, Kylie Engstrom

Honors Program Theses

In the past, students in general chemistry classes at the University of Northern Iowa have struggled with pre-labs due to cognitive overload.

The CLUE General Chemistry curriculum, which emphasizes the use of scientific practices, paired with a new SWH/ADI hybrid laboratory model was implemented in one of the sections of CHEM 1110 in the Fall 2019 semester. The goal of including these new features was to provide more scaffolding for …

How To Create A Radically Inclusive Math Classroom With Regards To Gender And Sexual Orientation, Alexa Devore

Honors Program Theses

An extensive literature review was conducted to analyze how a secondary mathematics teacher can best support female and LGBTQ students. While extensive research has been conducted about the gender gap in STEM, concerning female students, little research has been done that includes LGBTQ students. While female students have made great improvements in mathematics participation and achievement, there is still work to be done. LGBTQ students face similar difficulties as female students but have not received the same attention and research as female students. This research indicates there are more things teachers should be doing to support students who have been …

College Student Changing Attitudes And Beliefs About The Nature Of And Teaching Of Mathematics And Science, Stephen R. Skinner

Graduate Theses and Dissertations

With an estimated 17.3 million STEM jobs in the US, there exists a need for a STEMready workforce that is science literate with positive attitudes and beliefs toward the learning and teaching of mathematics and science (Graf, Fry, & Funk, 2018). However, the US has seen a steady decline in the number of high school students interested in STEM-related fields with only 16% of interested students with proven proficiency in mathematics and science and are ready to enroll in college STEM programs (ACT, 2017; Osborne & Dillon, 2008; Stake & Mares, 2001). With the decline in student interest, the US …

Students' Attitudes Towards Standardized Testing: A Literature Review, Kelly Gard

Curriculum and Instruction Undergraduate Honors Theses

Standardized testing is a task that all students must undertake during their educational careers. Standardized tests are large determinants to course placements, exceptionality placements, grades, school sanctions or rewards, and education policy. It is imperative that all students have an equal opportunity to succeed on standardized tests. However, bias, stress, and anxiety in standardized testing often hinders the opportunity for many students to excel on the tests.

The purpose of this literature review is to discuss the research conducted on standardized testing bias which includes the prevalence of testing bias as well as the causes and types of testing bias. …

Prompted Reflective Thinking And Implications For Mathematics Teacher Efficacy In An Elementary Mathematics Methods Course, Brooke Krejci

Dissertations and Theses @ UNI

Although student-centered mathematics instruction, rooted in constructivism (NCTM, 2014), enhances students’ deep understanding of mathematics, many teachers fail to implement this approach, continuing to use more traditional, procedural instruction (Paolucci, 2015). One reason for these difficulties may be related to their teaching selfefficacy, or a person’s beliefs about their ability to complete a task. Wyatt’s (2016) expanded teacher self-efficacy model incorporates the reflective cycle and emphasizes the importance of reflection in the development of teacher self-efficacy.

This study explored whether encouraging reflection in pre-service teachers may indirectly increase their use of student-centered methods in mathematics by increasing their self-efficacy. The …

A Single, Narrowly Focused Create Primary Literature Module Evokes Gains In Genetics Students’ Self-Efficacy And Understanding Of The Research Process, Alison Krufka, Kristy Kenyon, Sally G. Hoskins

Publications and Research

Exposure to primary literature using CREATE tools has been shown to have a positive impact on students’ self-efficacy and beliefs when incorporated into semester-long courses taught by extensively trained faculty. However, it is unknown whether similar benefits can occur with a brief exposure to CREATE in an otherwise traditionally taught course. We hypothesized that students who experienced a short-term CREATE module taught by faculty with minimal training in this pedagogy would make gains in scientific literacy and self-efficacy while also experiencing epistemological maturation. To test this hypothesis, we compared sections of students who experienced the CREATE module with sections of …

Teaching In A Total Institution: Toward A Pedagogy Of Care In Prison Classrooms, Lauren J. Wolf

Journal of Prison Education and Reentry (2014-2023)

This paper argues that a pedagogy of care can help reduce some of the human damage caused by incarceration. Rather than casting incarcerated men and women outside of the moral community and turning prisoners into a “them,” a pedagogy of care promotes inclusion and the creation of human connections. Recognizing prisoners’ humanity helps to dissolve some of the effects of institutionalization and may foster rehabilitation. Instead of limiting teachers to providers of information, as a traditional classroom expects, a pedagogy of care elevates teachers to human constituents of a learning community. This paper outlines a pedagogy of care in the …
