Using L1 Student Narratives And Peer Teaching To Increase Secondary Education Mathematical Understanding, Marco Antonio Martinez Leandro

Teacher Education, Educational Leadership & Policy ETDs

This phenomenological study research presents an option to use both discourse in the native language and technology as an alternative to improve the understanding of mathematics in secondary education. 13 students whose native language is Spanish attended a high school in a large urban school district in the Southwest of the United States, participated in this study.

The study's main objective was to observe the effects of using students' discourse in their language and the support of technology to increase their academic literacy in mathematics. Solution-based pedagogy was central to helping students achieve the Development of Academic Literacy in Mathematics …

Science, Technology, Engineering, And Mathematics (Stem) Project-Based Learning (Pbl) Education: A New Mexico Case Study For Equity And Inclusion, Kimberly A. Scheerer

Teacher Education, Educational Leadership & Policy ETDs

This research addresses how student participation in Science, Technology, Engineering, and Mathematics (STEM) project-based learning (PBL) education activities encourages underrepresented minority student achievement in STEM career field trajectories. Seven New Mexico high school counselors and 12 STEM organization personnel were interviewed during this study. Their responses represent the nuanced professional voices where New Mexico public education intersects with STEM student interest and cultural influence.

For students, STEM PBL can foster deep integration across educational disciplines and enhance STEM career trajectory interest and readiness. STEM education converged with PBL methodologies has the ability to leverage community support while broadening student networks. …

Speaker Diarization And Identification From Single-Channel Classroom Audio Recording Using Virtual Microphones, Antonio Gomez

Electrical and Computer Engineering ETDs

Speaker identification in noisy audio recordings, specifically those from collaborative learning environments, can be extremely challenging. There is a need to identify individual students talking in small groups from other students talking at the same time. To solve the problem, we assume the use of a single microphone per student group without any access to previous large datasets for training.

This dissertation proposes a method of speaker identification using cross-correlation patterns associated to an array of virtual microphones, centered around the physical microphone. The virtual microphones are simulated by using approximate speaker geometry observed from a video recording. The patterns …

Ngss-Based Constructivist Pedagogies: One Secondary Education Teacher’S Approach To Developing Student’S Science Identities, Massa Mafi

Teacher Education, Educational Leadership & Policy ETDs

This practitioner action research study explored features of NGSS-based pedagogies to improve secondary education student engagement, critical thinking, and collaborative problem-solving. It examined ways that constructivist pedagogies might encourage students to understand science by putting their skills and knowledge into practice as young engineers. The study involved 51 secondary education students from a large district in the southwest and focused on how NGSS inquiry-based learning can improve scientific understanding and skills within group work, the role that teacher support and modeling can play in learning, and how peer interactions can influence their scientific identities. Qualitative findings from teacher observations, classwork …

Situating Giving Back For Native Americans Pursuing Careers In Stem: “You Don’T Just Take, You Give Something Back”, Janet Page-Reeves, Gabriel Leroy Cortez, Yoenesha Ortiz, Mark Moffett, Kathy Deerinwater, Douglas Medin

Intersections: Critical Issues in Education

This article explores how a desire to give back influences Native Americans pursuing education and careers in science, technology, engineering and mathematics (STEM). We present analysis of data from 51 interviews with Native students and STEM professionals. Despite the compelling evidence of the core significance of a community orientation among Native Americans, insufficient attention has been given to thinking about the unique challenges faced by STEM professionals in devising ways to give back and how this relates to the continuing problem of under-representation of Native Americans in STEM. Here we propose strategies for universities and industry to honor Native ways …

An Analysis Of The Pregnancy And Childbirth Experiences Through Cultural And Mathematical Lenses, Maria T. Lopez-Flores

Shared Knowledge Conference

Being pregnant and giving birth is one of the most personal experiences. Nobody else but the pregnant woman can feel what she is feeling. However, her experiences during this process are highly influenced by her sociocultural context. In this, as in many other human activities, mathematics is present with or without realizing it. According to Frankenstein (1997), “mathematics occurs in contexts, integrated with other knowledge of the world” (p. 13). This project explores the mathematical and cultural practices that are embedded in the process of pregnancy and childbirth within two different sociocultural contexts: traditional Mexican partería (midwifery) and western medicine, …

Determining The Duration Of R&D Processes Through Monte Carlo Simulation, Florentin Smarandache, Moga Monika, Calefariu Gavrila, Sarbu Flavius Aurelian

Branch Mathematics and Statistics Faculty and Staff Publications

The research and development (R&D) processes influence the economic development of a company, because in an industry that is changing fast, firms must continually revise their projects and range of products. Therefore in order to determine the specific costs of research and development activity we have to highlight the efforts and effects of these activities and to calculate some indicators of economic efficiency. In the cost calculation process in R & D we have emphasized the identification of the components of cost and the duration of the R & D processes, as a component of the R&D cost, that is …

"American Examples For German Universities: Admitting Women Before World War I", Charles E. Mcclelland

History Faculty Publications

Women were not allowed to enroll a regular students in Prussian universities until 1909, although most other German states had already changed this policy. This chapter analyzes the terms of controversy swirling around the issue, and how American university policies ultimately helped bring about the change.
