Connecting Teachers’ Buy-Into Professional Development With Classroom Habits And Practices, Joshua B. Fagan, Kathleen Mary Melhuish, Eva Thanheiser, Brenda Rosencrans, Layla Guyot, Jodi I. Fasteen Oct 2019

Connecting Teachers’ Buy-Into Professional Development With Classroom Habits And Practices, Joshua B. Fagan, Kathleen Mary Melhuish, Eva Thanheiser, Brenda Rosencrans, Layla Guyot, Jodi I. Fasteen

Eva Thanheiser

While professional development (PD) provides an opportunity for teachers to cultivate skills that are consistent with best practices in the field, it is their buy-into the PD that ultimately determines the effectiveness of the PD. We examined how teacher buy-in affected the classroom habits and practice of four elementary teachers who took part in a district wide PD. Using baseline and first-year implementation video recordings, in conjunction with frameworks for discourse analysis, cognitive demand, and tools built specifically to measure PD implementation, we found that varying combinations of teachers' beliefs served as a mitigating factor for PD implementation.

Measuring Fidelity Of Implementation In A Large-Scale Professional Development Efficacy Study, Kathleen Mary Melhuish, Eva Thanheiser, Brenda Rosencrans

Eva Thanheiser

Fidelity of implementation is the essential link between professional development (PD) experiences and changes in outcomes. Yet, as a field we have few measures available to directly look at implementation. In this poster, we present our preliminary work measuring teachers’ implementation of a research-based PD.


The Language Of Professional Development Leaders, Andrew Riffel, Kathleen Mary Melhuish, Eva Thanheiser Oct 2019

The Language Of Professional Development Leaders, Andrew Riffel, Kathleen Mary Melhuish, Eva Thanheiser

Eva Thanheiser

Leaders in professional development (PD) initiatives (such as facilitators, principals, coaches) hold a great deal of power in their language, carrying the ability to manage meaning and frame experiences. Rather than working from interview data, this report addresses a gap in leadership research by examining the words used by leaders in their on-the-job interactions. We present an initial framework for capturing leadership language qualities at the macro level (framing the PD’s purpose) and micro level (rhetorical crafting in terms of metaphor usage, pronoun choice, and other language selections). Our data come from a larger project evaluating the efficacy of ...


Increasing Student Cognitive Engagement In The Math Classroom Through Sustained Professional Development, Eva Thanheiser, Brenda Rosencrans, Kathleen Mary Melhuish, Joshua B. Fagan, Layla Guyot Oct 2019

Increasing Student Cognitive Engagement In The Math Classroom Through Sustained Professional Development, Eva Thanheiser, Brenda Rosencrans, Kathleen Mary Melhuish, Joshua B. Fagan, Layla Guyot

Eva Thanheiser

We share the case of one teacher engaged in professional development (PD) designed to improve collective argumentation. We present an analysis of two lessons in her classroom, one before and one after her engagement with the professional development. Findings show that the classrooms differ across both teacher support for collective argumentation (requesting ideas and elaboration vs. requesting/acts and methods), and student contributions Oustifications vs. procedures and facts) .


Teacher Noticing Of Justification: Attending To The Complexity Of Mathematical Content And Practice, Kathleen Mary Melhuish, Eva Thanheiser, Jodi I. Fasteen, Julie Fredericks Oct 2019

Teacher Noticing Of Justification: Attending To The Complexity Of Mathematical Content And Practice, Kathleen Mary Melhuish, Eva Thanheiser, Jodi I. Fasteen, Julie Fredericks

Eva Thanheiser

In this report, we will consider in-service elementary school teachers' noticing of the mathematical practice: justification. This study is part of a larger project evaluating the efficacy of a three year professional development built around attending to student thinking and promoting mathematical habits of justifying, generalizing and making sense. Noticing just¢cation is a complex task requiring attention to both the (1) mathematical content and strategies and (2) the nature of the argument provided by a student. We have found that teachers' struggle to attend to both aspects simultaneously and offer a framework for considering teacher noticing of mathematical practices.

Since the inception of 3D printing, an evolutionary process has taken place in which specific user and customer needs have crossed paths with the capabilities of a growing number of machines to create value-added businesses. Even today, over 30 years later, the growth of 3D printing and its utilization for the good of society is often limited by the various users' understanding of the technology for their specific needs. This article presents an overview of current 3D printing technologies and shows numerous examples from a multitude of fields from manufacturing to education.

Integrating Online Instruction And Hands-On Laboratory Activities For Summer Learning For Students Of Color: A Design Case In Forensic Science, Douglas Elrick, Jiaqi Yu, Connie Hargrave

Constance P. Hargrave

The popularity of TV shows such as Crime Scene Investigation (CSI) has generated high school students’ interest in forensics. Yet, forensic science is not commonly accessible to students, and especially students of color who often attend under-resourced high schools. This article presents the design, development, and evaluation of an online forensics course created for high school students of color who were a part of an informal science, technology, engineering, and mathematics (STEM) educational development program. Two essential elements guided the course design: the target learners (high school students of color) and integrating online instruction and hands-on laboratory activities involving real-world ...

Project Excel: Web-Based Scanning Electron Microscopy For K-12 Education, L. Scott Chumbley, Connie P. Hargrave, Kristen P. Constant, Brian Hand, Thomas Andre, E. Ann Thompson

Constance P. Hargrave

Project ExCEL (Extended Classroom for Enhanced Learning) brings the capabilities of scanning electron microscopy (SEM) into classrooms. University and industry personnel, working together, have developed a web-based interface to allow schools to control a modern SEM. The interface allows a user control of the operating parameters of the microscope, stage movement, and chemical analysis. Such total control is not available on any other system. Since Iowa State University (ISU) pioneered the idea of remote SEM for education, researchers have learned that providing teachers access to sophisticated equipment does not ensure that it will be used. Teachers are busy, and structured ...

Constance P. Hargrave

The goal of Project ExCEL, the Extended Classroom for Enhanced Learning, is to bring the capabilities of Scanning Electron Microscopy (SEM) into elementary and secondary classrooms. We have developed an entirely web-based interface to allow schools to control a modern SEM. The web interface allows a remote user complete control of all the operating parameters of the microscope, including stage movement and x-ray chemical analysis. Such total control currently is not available on any other system. Since pioneering the idea of remote SEM use for K-12 education in the early 1990s, we have learned that merely providing schools and teachers ...

Scott Shappell

This study presents a compilation of 24 cases involving general aviation (GA) pilots’ weather encounters over the continental U.S. The project team interviewed pilots who had experienced a weather encounter, and we examined their backgrounds, flight experience, and weather encounter details. Results from meteorological data analysis for each weather encounter were consistent with findings of larger GA weather accident studies in terms of the types of hazards encountered and flight phase during which the encounters occurred. Investigation of pilot weather products and the sources from which they were obtained revealed a lack of uniformity of pre-flight data sources and ...

Pedro J. Llanos (www.AstronauticsLlanos.com)

The phenomenon of sloshing is a substantial challenge in propellant management, particularly in reduced gravity where surface tension-driven flows result in large slosh amplitudes and relatively long decay time scales. Propellant Management Devices (PMDs) such as the rigid baffles and elastomeric membranes are often employed to counteract motion of the free surface. In the present study, we investigate an active PMD that utilizes a free-floating membrane that, under an applied static magnetic field, becomes rigid and suppresses slosh. This semi-rigid structural layer can thereby replace bulky baffle structures and reduce the overall weight of the tank. In this paper, the ...

Engaging Undergraduate Students In Planetary Science Research For Parabolic Flights, Gillian Gomer, Adrienne Dove, Seamus Anderson, Jeffery Jorges, Alexandra Yates

Gillian Gomer

Microgravity investigations are key to understanding the behavior or regolith, or dusty granular material, that is ubiquitous on planetary surfaces. We see features on other planets that resemble avalanches and landslides seen here on Earth, while eroded craters and so-called ponds (smooth level dusty deposits at the bottom of some craters) reveal the action of various regolith flow mechanisms. The SLOPEs experiment was designed by an undergraduate group to address questions on the statics and dynamics of granular matter on the surfaces of small Solar System bodies, including a) the flow behavior of granular material along slopes (landslides and avalanches ...

Do Social Justice Contexts Matter In Mathematical Modeling?: Modeling Problem Analysis, Ji Yeong I, Ji-Won Son, Hyunyi Jung

Hyunyi Jung

Since the Common Core State Standards for Mathematics (CCSSM; NGA Center for Best Practices & CCSSO, 2010) include modeling as one of the eight Standards for Mathematical Practices for all grades but also as important conceptual category in high school mathematics, there have been a spotlight on mathematical modeling and demand for teachers to deliberately integrate modeling tasks in mathematics classrooms. One of the efforts to integrate modeling in mathematical curricula is including modeling problems in textbooks. It is necessary to examine if these attempts are adequately made in mathematical curricula (Meyer, 2015).

The Implications Of Teacher Performance Assessment And The Impact On Teacher Decision Making, Renee Rice Moran Nov 2018

The Implications Of Teacher Performance Assessment And The Impact On Teacher Decision Making, Renee Rice Moran

Renee Rice Moran

The issue of teacher accountability has been a part of the educational conversation for three decades, but only recently has this conversation been translated into policy as states begin directly tying teacher evaluation scores in part to student achievement on standardized tests. This qualitative study focuses on a group of teachers who are participating in this new form of evaluation (containing both qualitative and quantitative elements including test scores and lesson observations) and examines how they perceived the process. In particular, the study looks at how their personal reactions to a high-stakes evaluation impacted their instructional decision making in their ...
