Pre-Service Elementary Teachers' Framing Of Mathematical Discussions After Problem-Solving Through Mursion™ Simulation, Sezai Kocabas, Melva Grant, Signe Kastberg, Hanan Alyami

Teaching & Learning Faculty Publications

Research on pre-service teachers' discussion practices has focused on decompositions of practice into subskills, while acknowledging the importance of the role of context, identity, and relationships between interactive moves. We focused on 66 elementary preservice teachers' (PSTs') framing-launching moves in discussions after problem-solving in a MursionTM custom simulation. PSTs used five moves: gathering information about student processes, focusing on problem features, task and non-task oriented social interactions, and partner talk. Empirical findings of PSTs' intentions and tacit actions coupled with study findings of the diversity in PSTs' framing moves, highlight the complexity of teacher decision making involved in discussion subsills …

“Should Wellbeing Be The Same As Perfection?” A Case Study On Student Wellbeing In Higher Mathematics Education, Marcelo Alonso Almora Rios

Graduate Student Theses, Dissertations, & Professional Papers

Previous research has given the impression that reticent is our hunt for optimal teaching practices, educational goals, and nature of mathematical workings. In this regard, we have (seemingly) ended up with the following inquiries:

• What could the math classroom be for? and
• What has the math classroom been for?

These two questions touch on the scary horns of two other charged philosophical dandruffs. Namely:“What are the aims of teaching mathematics?” and “What should be our objectives in learning it?”

The term ‘positive education’ refers to an educational system engendering both the skills of positive wellbeing and traditional, academic achievement (Seligman …

Feed-Forward: Strengthening Assessment Of Pre-Primary And Primary Science And Mathematics Education In Tanzania, Nipael Mrutu, Esther Kibga

Institute for Educational Development, East Africa

Classroom assessment is a critical part of teaching and learning and is a potentially useful tool for enhancing learning outcomes. It provides information on where learners are with their learning goals and what they need to do to improve their understanding and meet the intended learning outcomes. In response to the agent's need for proper interpretation of classroom assessment, researchers and policymakers have developed guidelines, principles, and models to help teachers understand and implement effective assessment conceptions. Despite these initiatives, research continues to show that teachers struggle to interpret assessment policies and implement practices aligned with contemporary formative assessment notions. …

Identifying Potential Consequences Of Use Of A Measure Through Stakeholder Interviews, Melissa G. Kuhn, Joanna K. Garner, Shanan L. Chappell, Linda Bol

STEMPS Faculty Publications

The advent of Messick’s Contemporary Validity Theory (1994) led researchers in survey and measure design to develop and standardize qualitative and quantitative methods of collecting evidence for the validity of psychological instruments. However, one aspect of this theory, consequential validity, has few agreed-upon evidence-gathering methods (Furr & Bachrach, 2014). This study added a blueprint-driven interview method of collecting forecasted consequences of use of an instrument into the overall process of developing a measure of outreach impact on undergraduate engineering students (Authors, in press). The method, which included a purposeful sampling of end-users, is illustrated with thematically presented results. Potential implications …

Understanding And Advancing College Students' Mathematical Reasoning Using Collaborative Argumentation, Rachel Kay Heili

Graduate Theses/Dissertations

This study explored students’ mathematical reasoning skills and offered supports to advance them through a collaborative argumentation framework in a college intermediate algebra class. The goals of this study were to make observations about student reasoning, identify specific actions to address those observations, and document student growth in reasoning as a result of those actions. An iterative analysis, mixed method study was conducted in which the researcher engaged students in responding to questions that required conceptual understandings using a collaborative argumentation framework as a tool to identify and code components of their responses—claim, evidence, and reasoning. After coding and analyzing …

Alexander Von Humboldt: Explorer, Naturalist, And Environmental Pioneer (2019) By Danica Novgorodoff, Peter Shea

Picture Books

As a young boy, Alexander Von Humboldt came up with divergent questions about the birds and mountains and animals he saw, and brought all those questions together under two big questions that stayed important for him over a long life: “How are these things different?” and “How are they nevertheless connected?” As the reader watches Humboldt looking at a hawk and a mouse, volcanoes and farmland, palm trees and pine trees, Europe and Ecuador, Europeans and Indigenous people, one comes to expect what he will say: “They are different, and yet they are connected.” This idea is much bigger than …

Development And Implementation Of A Ngss Curriculum Unit For Astronomy In Ninth-Grade Earth And Space Science, Jessica Hughes

Graduate Research Papers

Since the release of the NGSS in 2013, there has been a gap in available curricula that is aligned with the new standards. To fill this gap, I created and implemented a unit of study aligned to the Next Generation Science Standards (NGSS) on the topic of astronomy for a ninth grade earth and space science course. Much of the available curriculum is above the level of ninth grade students. This curriculum approaches the astronomy standards at the level of ninth grade students.

The research questions were “how well does the curriculum prepare students for the disciplinary core ideas (DCIs) …

There is a disorder that is rather common within the world and yet is not well known. It is a something that affects one in every twenty-six individuals. It is called epilepsy. Epilepsy is a neurological disorder in which a person to experience bursts of random electrical activity within their brains, these bursts being called "seizures." This article discusses this disorder and goes into detail about the forms of it, procedures that are done to try and help those living with epilepsy, and artwork that is inspired by this disorder.

What Is Active Learning? Perspectives From Five Stem Professors' Teaching Practices In Their Classrooms, Iliana Correa

Capstone Showcase

This senior thesis investigated what ways, if any, STEM professors incorporated active learning pedagogy in their undergraduate classroom in a small private university in the northeast USA. STEM pedagogy was investigated because of the increasing prominence of active learning methods in the classroom compared to the didactic type of teaching that was prominent in the past (Eichler, 2020). A qualitative case study of five STEM professors was conducted and involved collecting data from biographical questions, a one-hour interview, and the analysis of a document provided by the professor that could have been a lesson plan, an assignment, or an activity …

This study was conducted to explore elementary teachers’ experiences and responses to issues with student engagement in their virtual Eureka Math classrooms during the Covid-19 Pandemic. A qualitative research design was used to conduct a hermeneutic, phenomenological study that included a document analysis, classroom observations, and semi-structured interviews using six elementary school teachers as participants. The resulting data was coded and triangulated using the thematic analysis of overarching themes, which …

Actividad 3: ¡Advertencia!, Patrick Young

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

En un ciclo de ingeniería y diseño se producen múltiples repeticiones de diseño. Esto es así desde el inicio de la idea hasta la instalación de una estructura de paso para animales. En el diseño hay que tener en cuenta más factores que los mencionados anteriormente, como la temperatura, las precipitaciones, el tráfico de vehículos, el ruido y los gases de escape de los vehículos.

Actividad 3: ¡Construye Rápido!, Patrick Young

Tema 1: Estructura y proceso

Uno de los costos de cualquier proyecto de carretera es el impacto económico de desviar el tráfico durante la construcción. Los métodos que minimizan las interrupciones reducen costos y suelen mejorar la seguridad. Los métodos de construcción acelerada de puentes (ABC, por sus siglas en inglés) incluyen la prefabricación de la mayor parte posible del puente fuera del lugar de la obra. Las piezas grandes se llevan al lugar y se instalan según un plan que minimiza el tiempo necesario para desviar el tráfico.

Activity 4: Testing Student-Made Concrete Decks, Patrick Young

Theme 1: Structure and Process

When a structural beam is loaded from above, the force creates compression on the upper surface and tension on the lower surface. Concrete can withstand ten times as much compression as it can tension. Since concrete is much less capable of supporting tension, it is along the bottom that steel reinforcement is most important.

Activity 3: Traffic Management, David Hernandez, Peg Steffen

Theme 3: Traffic Management

Traffic management in busy urban areas is an extremely complex problem. Issues such as traffic congestion from home to work, suburban growth, preservation of scenic landscapes and historic neighborhoods, and the ability to walk, bike, and access public transit make traffic management a challenge. Traffic Management can include lane closures, detours, pedestrian access, and speed limits. It also includes intersections engineered for safe passage of vehicles in a stream of traffic that must cross each other's paths. Complicating factors for intersections include bikes, pedestrians, and emergency vehicles.

Activity 3: Rooting For You, Karen Ye

Theme 4: Please Pass the Salt

Snow and ice removal are needed in winter for safe roads. Salt is very effective along with other chemicals, but these may cause harm to plants, wildlife, and humans. Salt seeps into groundwater and may create problems with water resources. High levels of salt affects the amount of oxygen in water, organism growth, reproduction, and food sources. Whether the chemicals cause harm to an organism depends on the amount of chemicals and how long the organism is exposed to them. Salt can also reduce soil minerals and absorb water that plants need. Other impacts on plants include leaf damage, stunted …
