An Analysis Of Non-Comparison Based Sorting Algorithms, Jacob M. Gomez, Edgar Aponte, Brad Isaacson May 2022

An Analysis Of Non-Comparison Based Sorting Algorithms, Jacob M. Gomez, Edgar Aponte, Brad Isaacson

Publications and Research

Sorting algorithms put elements of a list into an order (e.g., numerical, alphabetical). Sorting is an important problem because a nontrivial percentage of all computing resources are devoted to sorting all kinds of lists. For our project, we implemented two non-comparison based sorting algorithms from pseudocode and compared them to various comparison based sorting algorithms. The two algorithms have their advantages and disadvantages as well as their unique features. We found that Radix Sort (which is a modified version of Counting Sort) was the most efficient of them all.

Understanding The Transition From General To Organic Chemistry, Hannah Chan May 2022

Understanding The Transition From General To Organic Chemistry, Hannah Chan

Student Scholar Symposium Abstracts and Posters

Organic chemistry is commonly known to have high failure rates and regarded as one of the most difficult courses offered in undergrad. This study assessed whether a modified general chemistry curriculum allowing for more time focused on foundational organic chemistry concepts in general chemistry can improve students’ grade outcome and/or self efficacy when transitioning from general to organic chemistry courses. Two separate variables were tested: grade outcome and self efficacy. Using an independent sample t-test, a comparison of the two groups (modified versus traditional general chemistry) was performed. Grades were assessed by giving students four questions (out of 4 ...

Bridging The Research-Practice Gap: Development Of A Theoretically Grounded Workshop For Graduate Students Aimed At Challenging Microaggressions In Science And Engineering, Amy C. Moors, Lindsay Mayott, Benjamin Hadden Apr 2022

Bridging The Research-Practice Gap: Development Of A Theoretically Grounded Workshop For Graduate Students Aimed At Challenging Microaggressions In Science And Engineering, Amy C. Moors, Lindsay Mayott, Benjamin Hadden

Psychology Faculty Articles and Research

Efforts to promote diversity and inclusion often lack a theoretical basis, which can unintentionally exacerbate issues. In this paper, we describe the development and evaluation results of a theoretically grounded workshop aimed at reducing microaggressions and promoting ally engagement among graduate students in science and engineering. In Study 1, using a Delphi method, eight science and engineering faculty members with backgrounds in diversity efforts provided feedback on workshop development. In Study 2, 107 graduate and advanced undergraduate students engaged in the 90-minute interactive workshop. Results indicate that attendees found the workshop valuable, developed new skills for ally engagement, and planned ...


Using Video Recordings To Support Meaningful Reflection Of Mathematical Teaching Practices, David Scalzo Apr 2022

Using Video Recordings To Support Meaningful Reflection Of Mathematical Teaching Practices, David Scalzo

Honors Theses, University of Nebraska-Lincoln

The practice of teaching mathematics is a skill that can be continually built upon. In order to maximize the effectiveness of one’s math lessons, it is essential that they become a reflective teacher. This project explains the importance of reflecting on mathematical teaching practices, then outlines the steps I have taken to start becoming a reflective teacher. Video recordings working with math are included as part of the project, which are used as the material I reflect about.


Undergraduate Students’ Accuracy & Confidence In Detecting Errors In Biological Models Related To Gpa, Mckenna Elliott, Joseph Dauer, Carrie Clark, Mei Grace Behrendt Apr 2022

Undergraduate Students’ Accuracy & Confidence In Detecting Errors In Biological Models Related To Gpa, Mckenna Elliott, Joseph Dauer, Carrie Clark, Mei Grace Behrendt

UNL Student Research Days Posters, Undergraduate

Research Questions 1. Does students’ abilities to Accurately detect errors relate to their GPA? 2. Which concepts affect student ability to Accurately and Confidently detect errors?

GPA was positively related to accuracy but was unrelated to confidence (Fig. 1)

Subject areas affected students’ accuracy and confidence § Students were more accurate on ecology & evolution models (Fig. 2) § Students were more confident in ecology models and less confident in physiology models (Fig. 2)

Variation in student ability and subject area competency can provide teachers with places to focus and improve science understanding.

Similar to the work of Clark et al 2020, this ...

Twitter: More Than Tweets For Undergraduate Student Researchers, Nathan S. Reyna, Christin Pruett, Mike Morrison, Jennifer Fowler, Sumali Pandey, Lori Hensley

Articles

During the COVID-19 pandemic, biology educators were forced to think of ways to communicate with their students, engaging them in science and with the scientific community. For educators using course-based undergraduate research experiences (CUREs), the challenge to have students perform real science, analyze their work, and present their results to a larger scientific audience was difficult as the world moved online. Many instructors were able to adapt CUREs utilizing online data analysis and virtual meeting software for class discussions and synchronous learning. However, interaction with the larger scientific community, an integral component of making science relevant for students and allowing ...

A Twofold Approach To Addressing Under-Representation In Science, Matt Harding Apr 2022

A Twofold Approach To Addressing Under-Representation In Science, Matt Harding

Science Education Update Conference Documents

I teach in one of the largest public school districts in Iowa, and have always been bothered by how the demographics of my course rosters differ significantly from the diverse enrollment at my school. My talk will address some of what can be done to reduce gate keeping that limits opportunities for students that might not typically take courses like AP Physics, how I have managed to push-in to our ELL introductory science course with many of the same activities that I use in my grade level and AP physics courses, as well as my experience with AIP's STEP ...
