Insight From Biology Program Learning Outcomes: Implications For Teaching, Learning, And Assessment, Noelle Clark, Jeremy L. Hsu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Learning goals and objectives are a key part of instruction, informing curricular design, assessment, and learning. These goals and objectives are also applied at the programmatic level, with program learning outcomes (PLOs) providing insight into the skills that undergraduate biology programs intend for their students to master. PLOs are mandated by all major higher education accreditation agencies and play integral roles in programmatic assessment. Despite their importance, however, there have not been any prior attempts to characterize PLOs across undergraduate biology programs in the United States. Our study reveals that many programs may not be using PLOs to communicate learning …

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 …

La gestión de proyectos es la disciplina que consiste en planificar y controlar el trabajo de un equipo para alcanzar un objetivo específico. El éxito de la gestión de proyectos requiere una cuidadosa consideración de los plazos, los presupuestos y los recursos disponibles.

El diagrama de Gantt es una herramienta de gestión de proyectos que muestra las tareas en términos de su tiempo de ejecución, interdependencia y recursos disponibles. Desarrollado por el ingeniero estadounidense Henry Gantt, este diagrama se empleó por primera vez en la construcción naval, …

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.

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 …

Actividad 4: Reduzca La Velocidad, Se Aproximan Curvas, Patrick Young

Tema 2: Por la ciudad

Diseñar una carretera conlleva tomar muchas decisiones. En un mundo ideal, todas las carreteras tendrían una superficie plana y recta. Lamentablemente, no es así porque las carreteras tienen muchos desvíos, intersecciones, numerosos automóviles transitando y semáforos. Los ingenieros eligen la velocidad máxima de la carretera en función de las características de equilibrio del terreno, el tráfico, los obstáculos existentes y, lo que es más importante, la seguridad.

El objetivo principal de una carretera es asegurarse de que los vehículos puedan maniobrar a una velocidad determinada de forma segura. Por ejemplo, no verá un límite de velocidad de 60 millas por …

Actividad 2: Solo De Paso, Patrick Young

Tema 5: ¿Por qué la gallina cruzó la calle?

Los pasos para animales para la fauna silvestre son cada vez más frecuentes. Su objetivo es proporcionar un camino seguro para que los animales crucen las barreras hechas por el hombre, en este caso las carreteras. Las escaleras para peces, patentadas en 1837, son un ejemplo temprano de este tipo de intervención. Además, los pasos proporcionan a los animales el acceso a los recursos del otro lado de la barrera. Los pasos ayudan a conectar los hábitats para evitar la fragmentación de los mismos, lo que puede restringir el acervo genético y dar lugar a poblaciones más bajas y en …

Activity 5: Slow Down, Curves Ahead, David Hernandez, Peg Steffen

Theme 2: Around Town

Highway curves are banked so the outside edge of the roadway is elevated above the inside edge. This provides additional centripetal force to keep the car on the road and following the proper path. The faster a car is moving, the more banking it will need.

Activity 3: Warning!, Elizabeth Martinez

Theme 5: Why Did the Chicken Cross the Road?

More factors than previously mentioned must be considered in the design of an animal crossing structure, such as temperature, precipitation, vehicle traffic, noise, and vehicle exhaust. Consideration of these environmental factors and events will require modifications to the original design. This is a common practice in engineering. The original design might go through several revisions as modeling, testing, and experience reveal the need for modifications.

Actividad 4: Prueba De Las Cubiertas De Hormigón Fabricadas Por Los Estudiantes, Patrick Young

Tema 1: Estructura y proceso

Cuando una viga estructural se carga desde arriba, la fuerza crea compresión en la superficie superior y tensión en la superficie inferior. El hormigón puede soportar la compresión diez veces más que la tensión. Como el hormigón tiene menos capacidad para soportar la tensión, el refuerzo de acero es más importante en la parte inferior.

En esta actividad, los estudiantes realizarán una prueba de carga en 3 puntos para ver cuánto peso pueden soportar sus losas.

Actividad 3: Curva Pronunciada, Patrick Young

Tema 2: Por la ciudad

La forma de una curva afecta la facilidad con la que un automóvil puede circular con seguridad por ella. Las colisiones son más probables cuando la curva es demasiado cerrada. La curva debe ser suave, la transición entre los tramos rectos y curvos de la carretera también deben ser suaves.

En la imagen anterior, el automóvil experimenta una fuerza (llamada “fuerza centrípeta”) que lo empuja hacia el centro del círculo. Se trata de una fuerza de fricción proporcionada por la carretera que actúa sobre los neumáticos. Cuanto más cerrada es la curva, más fricción se necesita para mantenerse en la …

Activity 1: Build It Strong!, Patrick Young

Theme 1: Structure and Process

Materials like concrete and steel are important components of highway construction, but so are management tools such as planning and scheduling. This theme, Structure and Process, attempts to integrate these components using the construction of a highway overpass as an example. Activities should be done in the order presented. The concrete made in Activity 1 will need two days to cure before being tested in Activity 4.

Activity 1: Adela Valley Highway, Patrick Young, David Hernandez

Theme 2: Around Town

If you ask a longtime resident of your neighborhood what the town was like 30 or 40 years ago, they will tell you that there were a lot of empty spaces or fields. Ask them if they are happy with the numerous homes, businesses, roads, and industries that now exist. They may say that they lost part of their community. At the same time, they gained jobs, property value, and infrastructure improvements.

Whether to build more roads through a town is not an easy decision. There has to be a clear implementation plan, local or state funding, city code agreement, …

Activity 2: Cost Analysis, Patrick Young, David Hernandez

Theme 2: Around Town

The unit cost of highway construction varies tremendously, but state departments of transportation often publish estimates. For this activity, we assume that a four-lane divided highway will cost $5 million per mile across flat farmland.

Activity 3: Navigation, Patrick Young, David Hernandez

Theme 2: Around Town

Highways of the future will be more than ribbons of concrete and asphalt. They will have an information infrastructure that includes sensors, computers, and wireless connection with the computers in every moving vehicle. In the same way that people are connected by the internet, vehicles will be connected with each other through the highway’s network. This will enable drivers using navigation software to get real-time updates and suggestions. It will also increase the safety and efficiency of driverless vehicles.

In this activity, students will use mathematics to examine the types of calculations that navigational computers use to redirect drivers to …

Activity 2: Anger Management, David Hernandez, Peg Steffen

Theme 3: Traffic Management

Road rage is anger caused by inconveniences, incidents, or irresponsibility while driving. It can result in yelling, honking, tailgating, weaving, and blocking traffic. Road rage fatalities are increasing but there are strategies to help lessen road rage. These include overhead signs warning of upcoming traffic, weather, and car or truck incidents. Traffic and travel apps, which offer various route suggestions, travel times, and road hazards, may help as well. This activity will examine personal behaviors that drivers should exhibit to reduce road rage and then asks students to consider strategies to reduce this growing issue.

Activity 4: Information Board, David Hernandez, Peg Steffen

Theme 3: Traffic Management

In 1969, the National Household Travel Survey (NHTS) began collecting data about Americans’ travel habits. During the survey period, each household was sent a travel diary and asked to report all travel by household members on a randomly assigned “travel day”. Data were weighted to correctly reflect the day of week and month of travel to allow comparisons of weekdays or seasons. The type of transportation used, length and distance of trips and the purpose of travel are some examples of data gathered through the surveys. Organizations such as insurance companies, transportation agencies, and the government analyze and use the …

Activity 2: A Little Bit Salty, Karen Ye

Theme 4: Please Pass the Salt

Density is defined as the amount of mass that takes up a certain amount of volume. Adding salt or sugar to water increases its density since there are more particles (mass) packed into a similar amount of space (volume). Cooling water can also increase its density since the particles move more slowly at lower temperatures and will be more packed together. When two substances with different densities are combined, the one with a lower density will float whereas the one with a higher density will sink. The greater the difference in density, the more distinct the layers and the harder …

Activity 1: A Day In The Life, Patrick Young

Theme 5: Why Did the Chicken Cross the Road?

All highways run through animal habitats. Fencing highways can provide drivers some protection from animal-related accidents, but they fragment the habitat, causing problems for wildlife. In this activity, students learn some of the reasons that animals will attempt to cross highways.

Activity 2: Just Passing Through, Elizabeth Martinez

Theme 5: Why Did the Chicken Cross the Road?

Animal passages for wildlife are becoming more prevalent. Their purpose is to provide a safe path for animals to cross man-made barriers, in this case roadways. Fish ladders, patented in 1837, are an early example of this type of intervention. In addition, passages provide animal access to resources on the other side of the barrier. Crossings help to connect habitats to avoid habitat fragmentation, which can restrict the gene pool resulting in lower and more at-risk populations, as well as potential extinction. Vehicle and wildlife collisions account for many injuries and deaths for humans and other animals, property damage, and …

Becoming A Stem-Focused Catholic School: Insights Into Adopting A Curricular Specialization, Julie W. Dallavis

Journal of Catholic Education

School choice policies seek to increase access to educational opportunities and stimulate innovations in schooling. This study examines the early stages of one such innovation—school-wide curricular specialization—in three Catholic elementary schools adopting a STEM focus and uses interviews to consider how and why different levels of support exist for the shift and under what conditions private and religious schools are prepared to make significant changes in instructional practice. Findings suggest that school resources—material, human, and social along with professional development—play an important role in shaping engagement in the adoption of a school-wide curricular focus.
