Gaining Access To The Language Of Science: A Research Partnership For Disciplined, Discursive Ways To Select And Assess Vocabulary Knowledge, H. Emily Hayden, Anupma Singh, Michelle Eades Baird Oct 2019

Gaining Access To The Language Of Science: A Research Partnership For Disciplined, Discursive Ways To Select And Assess Vocabulary Knowledge, H. Emily Hayden, Anupma Singh, Michelle Eades Baird

Emily Hayden

To equalize access to science learning across genders and demographic groups, access to the disciplinary language of science is one place to start. The language of science is highly challenging and specialized, and difficulties acquiring this language contribute to disparities in science achievement across diverse student groups. This study used a pre-post design to analyze effectiveness of a brief classroom science vocabulary assessment designed to assess receptive and productive vocabulary knowledge across multiple sections of one 7th grade science teacher’s class. Vocabulary was selected and analysis conducted by an interdisciplinary research partnership including the science teacher, a literacy ...


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

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.

The Potential Of Socio-Biologically Relevant Mobile Applications To Attract Girls To Stem, Vanaja Nethi, Santanu De May 2019

The Potential Of Socio-Biologically Relevant Mobile Applications To Attract Girls To Stem, Vanaja Nethi, Santanu De

Santanu De

Stimulating girls’ interest in science, technology, engineering and mathematics (STEM) when they are in school, and sustaining that interest, is critical in motivating girls to choose STEM-related disciplines in higher education and enter STEM careers. Research indicates that girls show an interest in STEM until about 11-12 years of age, but this starts to wane by the time they are 15-16 years. Thus, there is a clear need to focus on sustaining the interest of girls in STEM at middle or high school levels. Research has shown that one of the main drivers that impact girls’ interest in STEM is ...

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 ...

Project Excel—Web-Based Sem For K–12 Education, L. Scott Chumbley, Kristen P. Constant, Connie P. Hargrave, Tom Andre

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 ...


Educating Nursing Students For Practice In The 21st Century, Jennifer Emilie Mannino Ph.D., R.N., Elizabeth Cotter Ph.D, R.N. May 2019

Educating Nursing Students For Practice In The 21st Century, Jennifer Emilie Mannino Ph.D., R.N., Elizabeth Cotter Ph.D, R.N.

Jennifer E. Mannino, PhD, RN

Nurses face a number of challenges in the 21st century. One major challenge pertains to nursing education, specifically to the entry into practice preparation of undergraduate nursing students. Not only do nurses need to be adequately prepared to care for an ever increasing complex patient population, but they are called upon to be leaders in healthcare. The ways in which nurses were educated during the 20th century are no longer adequate for dealing with the realities of health care today; and having a baccalaureate degree alone does not always prepare new graduate nurses for the complexities of today’s health ...

Examining Validity And Reliability Of A Mathematics Assessment Tool For K-2 Students, Carl F. Siebert, Jonathan L. Brendefur

Carl Siebert

The Primary Math Assessment (PMA) tool is increasingly being used in multiple districts in a northwestern state. The PMA provides both screening and diagnostic information in six domains to assess mathematical proficiency in young students in their early educational years. A previous study using multidimensional Rasch analyses found support for the PMA’s six-dimensional theoretical framework, and that the PMA is a reliable mathematics assessment for early grades. This study extended the examination of a Rasch model, implementing exploratory and confirmatory factor analysis, Item Response Theory, and Differential Item Functioning analyses. In doing so, this study found an IRT 2-PL ...

Magneto-Active Slosh Control System Using Free Floating Membrane For Cylinderical Propellant Tanks Read More: Https://Arc.Aiaa.Org/Doi/Abs/10.2514/6.2019-2177, Pedro Llanos

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 ...

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).
