Still A Private Universe? Community College Students’ Understanding Of Evolution, Meredith A. Dorner, Philip Sadler, Brian Alters

Education Faculty Articles and Research

Background

Measuring what students know and retain about evolution is essential to improving our understanding of how students learn evolution. The literature shows that college students appear to have a poor understanding of evolution, answering questions on various instruments correctly only about half of the time. There is little research regarding evolution understanding among community college students and so this study examines if those students who are enrolled in life science classes, who are assessed using questions based on grade eight standards, show a better understanding of evolutionary principles than younger students and if there are differences in knowledge based …

Actividad 1: Más Fresco Que Yo, Patrick Young

Tema 4: Por favor, pásame la sal

La materia está formada por átomos y moléculas. Aunque no podremos verlas con nuestros ojos, estas pequeñas partículas se mueven constantemente. La temperatura de una sustancia es una medida de su energía cinética promedio (la energía que tiene debido al movimiento de las partículas). A medida que aumenta la temperatura, las partículas adquieren más energía, se mueven más rápidamente y se separan más.

No importa en qué lugar de Illinois viva, el clima invernal nos impacta a todos. El deshielo y la limpieza de nieve representan una gran parte del presupuesto para las carreteras estatales y locales. La sal se …

Activity 2: The Pb&J Project, Patrick Young

Theme 1: Structure and Process

Complex projects, such as bridge construction, require thoughtful planning. Project Management is the discipline of planning and controlling the work of a team to reach a specific goal. Successful Project Management requires a careful consideration of deadlines, budgets, and available resources.

The Gantt chart is a project management tool that shows tasks in terms of their time-to-complete, interdependency, and available resources. Developed by American engineer Henry Gantt, these charts were first employed in shipbuilding, the construction of the Hoover Dam, and the Interstate Highway System.

Today they are used for all manner of project management tasks. Computers have made the …

Actividad 1: ¡Construye Fuerte!, Patrick Young

Tema 1: Estructura y proceso

El hormigón es el material de construcción más común para estructuras grandes. El hormigón se compone de tres materiales:

• Áridos: Arena y grava.
• Cemento: Un pegamento químico que mantiene los agregados unidos con gran fuerza.
• Agua: El agua no solo ayuda a mezclar y verter el hormigón, sino que se une al cemento en una reacción química y se incorpora al hormigón terminado.

Las cubiertas de los puentes deben soportar el peso de todos los automóviles y camiones que transitan por ellos. Las diferentes partes de las cubiertas de los puentes experimentan distintos tipos de fuerzas. La compresión es una …

Actividad 1: Lo De Adela, Patrick Young

Tema 2: Por la ciudad

Si pregunta a algunos de los residentes más antiguos de su barrio cómo era la ciudad hace 30 o 40 años, le dirán que había muchos espacios o campos vacíos Si les pregunta si están contentos con las numerosas viviendas, comercios, carreteras e industrias que existen ahora, es posible que digan que han perdido parte de su comunidad, pero que, al mismo tiempo, han ganado en infraestructuras, carreteras, industrias, puestos de trabajo, valor de la propiedad y expansión de la comunidad.

Implantar más carreteras en una ciudad no es una decisión fácil. Para que el proyecto se lleve a cabo, …

Actividad 2: Ruta Óptima, Patrick Young

Tema 2: Por la ciudad

Los sistemas de navegación de los vehículos utilizan información de la ubicación para ayudar a los conductores a decidir qué ruta tomar. Muchos de los sistemas de navegación alertan a los conductores de peligros en la carretera. Los cierres de carreteras, los accidentes, el clima y otros peligros afectan tanto los tiempos de viaje como las rutas elegidas. La colaboración y el intercambio de información entre la autopista o carretera, los servicios públicos y los sistemas de navegación son necesarios para informar a los conductores.

Activity 4: High Visibility Signs, Patrick Young

Theme 2: Around Town

Highway signage has evolved over time in response to driving habits and advances in automotive technology and materials science. Although most informational signs have a nondescript appearance, the microscopic structure of their surfaces is complex. Many competing designs attempt to provide advantages when illuminated by headlights.

It is often true that designing a test to evaluate different items is as important and challenging as designing the items themselves. In this activity, students will design both highway signs and a reliable procedure for testing them.

Activity 1: Traffic Jam, Patrick Young, Peg Steffen

Theme 3: Traffic Management

Computer models can be excellent tools for analyzing complex systems. In this activity, students will use a web-based computer model to explore the relationship between the volume of traffic and the time it takes for vehicles to get from point A to point B. Then they will use the model to assess two potential solutions to their particular example of traffic congestion. Students will be comparing small samples with larger samples to appreciate the benefits of using large, random samples.

Decline Is Not Inevitable: Changes In Science Identity During The Progression Through A U.S. Middle School Among Boys And Girls, Julia Mcquillan, Patricia Wonch Hill, Joseph C. Jochman, Grace Kelly

Worlds of Connections Resources

In the United States, science capital is important for navigating many aspects of life. Yet during middle school, science interest declines more for girls than boys. It is unclear, however, whether science identity also declines during the middle school years and if there are differences by gender. The authors advance prior research by modeling changes in science identity and associations with changes in identity-relevant characteristics using growth curve analyses on four waves of data from 760 middle school youth. For girls and boys, science identity changes over time; about 40 percent of the variance is within-person change, with the remainder …

The Proof Is In The Pudding – Using Perceived Stress To Measure Short-Term Impact In Initiatives To Enhance Gender Balance In Computing Education, Alina Berry, Sarah Jane Delany

Academic Posters Collection

The problem of gender imbalance in computing higher education has forced academics and professionals to implement a wide range of initiatives. Many initiatives use recruitment or retention numbers as their most obvious evidence of impact. This type of evidence of impact is, however, more resource heavy to obtain, as well as often requires a longitudinal approach. There are many shorter term initiatives that use other ways to measure their success.

First, this poster presents with a review of existing evaluation measures in interventions to recruit and retain women in computing education across the board. Three main groups of evaluation come …

A Phenomenological Study Of Science Teachers’ Lived Experience: Pedagogical Judgment During The Covid-19 Pandemic, Amy Vo

Electronic Theses and Dissertations

At the beginning of the COVID-19 pandemic, in March of 2020, education in the United States changed dramatically. Science teachers began to look at the implementation of ambitious and equitable science teaching practices differently. Employing the hermeneutic phenomenological framework, the purpose of this study was to investigate the lived experience of science teachers, specifically looking at their pedagogical judgment related to ambitious and equitable science teaching. Semi-structured interviews, artifacts and surveys were used to develop a rich description of the phenomenon. Data analysis of the science teachers’ narratives, Qualtrics surveys, and lesson plans illuminated six essential themes common to all …

Elementary Preservice Math Teachers’ Evolving Dispositions Throughout A Math Methods Course: A Mixed Methods Study, Christine E. Hood

Electronic Theses and Dissertations

This study aimed to understand graduate-level Elementary Preservice Teachers’ (EPST) mathematical dispositions before, during, and after a graduate elementary math methods course taught through a rehumanizing (Gutiérrez, 2018), ambitious and equitable math (Horn & Garner, 2022) teaching framework. In this study, EPSTs’ dispositions included four constructs: math anxiety, math teaching anxiety, math self-efficacy, and math teacher self-efficacy. To fully understand the nuance and complexity of teacher education and EPSTs’ mathematical dispositions, I looked at both the EPSTs' and the instructors' perspectives. I investigated EPSTs’ dispositions through a modified multi-methods, sequential, and phenomenological lens. For the instructors’ perspectives, I conducted a …
