AAS: Quasar clustering (pptx, pdf); Novice/Expert characteristics in astronomy database learning(pptx, pdf)
ASTE: Novice/Expert characteristics in teachers learning to work with astronomy databases (pptx presentation, docx paper)


I am joint advised by Dr. Adam Myers in the Physics & Astronomy department, and Dr. Andrea Burrows in the Secondary Education department.

My thesis is titled "Astronomical Databases: Quasar Clustering in SDSS DR7, and Novice/Expert Characteristics in Learners." The written thesis proposal can be found here, but in short it is interdisciplinary, with one component based on the clustering properties of radio-loud vs. radio-quiet quasars, and another part based on the novice/expert transition in students as regards handling sets of data in Astro 101.

Title: What Can I Do with All of These Numbers?: Exploring STEM Dataset Use
Authors: Schwortz, Andria C.; Burrows, Andrea C.
Resources: Presentation
Dataset skills are used in STEM fields from healthcare work to astronomy research. Few fields explicitly teach students the skills to analyze datasets, and yet the increasing push for authentic science implies these skills should be taught. The authors studied a matched set of participants (n=87) working with Google Sheets to analyze a 200-entry dataset of astronomical data. Participants were university undergraduate students, and science educators consisting primarily of K-12 STEM teachers and science fiction writers. Participants explored a three-phase dataset activity and were given an eight-question multiple-choice pre/post-test covering skills of analyzing datasets and astronomy content, with questions spanning Bloom’s Taxonomy. Pre/post-test scores were compared and a t-test performed for subsamples by population. Participants exhibited an increase in both dataset skills and astronomy content, indicating that dataset skills can be learned through this astronomy activity. Participants exhibited gains in both recall and synthesis questions, indicating that learning is non-sequential. Female undergraduate students exhibited lower levels of learning than other populations. Implications include a stronger dataset focus in post-secondary STEM education and among science educators, and the need for further investigation into the challenges faced by female undergraduate students.

AAS Summer 2014

Title: Initial Development and Pilot Study Design of Interactive Lecture Demonstrations for ASTRO 101
Authors: Schwortz, Andria C.; French, D.A.; Gutierrez, Joseph V.; Sanchez, Richard L.; Slater, Timothy F.; Tatge, Coty

Awards: Chambliss Astronomy Achievement Student Awards (Honorable Mention)
Interactive lecture demonstrations (ILDs) have repeatedly shown to be effective tools for improving student achievement in the context of learning physics. As a first step toward systematic development of interactive lecture demonstrations in ASTRO 101, the introductory astronomy survey course, a systematic review of education research, describing educational computer simulations (ECSs) reveals that initial development requires a targeted study of how ASTRO 101 students respond to ECSs in the non-science majoring undergraduate lecture setting. In this project we have adopted the process by which ILDs were designed, pilot-tested, and successfully implemented in the context of physics teaching (Sokoloff & Thornton, 1997; Sokoloff & Thornton, 2004). We have designed the initial pilot-test set of ASTRO 101 ILD instructional materials relying heavily on ECSs. Both an instructor's manual and a preliminary classroom-ready student workbook have been developed, and we are implementing a pilot study to explore their effectiveness in communicating scientific content, and the extent to which they might enhance students' knowledge of and perception about astronomy and science in general. The study design uses a pre-/post-test quasi-experimental study design measuring students' normalized gain scores, calculated as per Hake (1998) and Prather (2009), using a slightly modified version of S. Slater's (2011) Test Of Astronomy STandards TOAST combined with other instruments. The results of this initial study will guide the iterative development of ASTRO 101 ILDs that are intended to both be effective at enhancing student achievement and easy for instructors to successfully implement.

NES AAPT Spring 2014

Title: A Review of Educational Computer Simulations for Interactive Lecture Demonstrations in Introductory Astronomy Survey Courses
Authors: Schwortz, Andria C.; French, D.A.; Gutierrez, Joseph V.; Sanchez, Richard L.; Slater, Timothy F.; Tatge, Coty
Resources: Poster, References
Despite many introductory astronomy survey course instructors' seeming reluctance to readily adopt new educational technology, the reality is that many of them are already unknowingly doing so by projecting PowerPoint presentations, showing classroom videos, leading planetarium and observatory tours, showing desktop planetarium simulation software, and using online homework systems (e.g., MasteringAstronomy). Much more prevalent in the domain of physics teaching, physics instructors have more readily adopted supplements to traditional lecture by using interactive lecture demonstrations (ILDs). Unfortunately, the nature of conventional astronomy teaching has made some of the more widespread physics teaching innovations rather difficult to easily implement in ASTRO 101 classrooms. As a first step toward systematic development of ILDs in ASTRO 101, a review of education research summarizing the effectiveness and practical realities of adopting educational computer simulations (ECSs) and ILDs specifically in astronomy reveals that initial development efforts require a more targeted and purposeful effort to increase adoption and effectiveness in an astronomy lecture setting.

Educational Computer Simulations
Style: Literature review
Course: Cognition in Math and Science Education (term paper)
Utilizing technology in the classroom is "all the rage" these days - this is common knowledge in not only educational circles but also in the public consciousness. But contrary to the popular opinion of this being a modern phenomenon, both computer and physical simulations have been used for educational purposes for longer than my lifetime. Lunetta and Hoffstein (1981) cite Glazer as studying the use of simulations in military training as early as 1960. Both enthusiasm and criticism have followed, stemming from researchers, educators, learners, and the general public. It might be expected that in the intervening years many questions would have been settled about the educational use of technology, however as the power of computers has advanced (from mainframes the size of a room to iPhones that fit in a pocket) so too have the educational uses of computers. While studies of the use of technology have also advanced, there remains much to be investigated still.

Searching for NEOs in SDSS Stripe 82.
Style: Original research
Course: Data Mining in Large Astronomical Surveys (term paper)
Near-Earth objects (NEOs) can pose a significant threat to life on Earth, depending upon their probability of impact, size, and how long ahead of a potential impact they are discovered. Mining SDSS data provides a nice opportunity for us to expand the number of NEOs identified without requiring additional equipment or time on existing telescopes. Herein I propose a method of mining SDSS DR8 coadd data and time dependent SDSS Stripe 82 data to discover fast-moving asteroids. This method results in the identification of an upper limit of 233 candidate NEOs within Stripe 82 posessing velocities in the range 0.5<v<2.5 deg/day.

Waterworlds: Structures / Properties and Discoveries of Ocean Planets.
Style: Literature review
Course: Exoplanets (term paper)
In recent years a number of surveys, including the MEarth project (located in Arizona and run out of Cambridge, MA), and the COROT and Kepler space missions, have been dedicated to the discovery of extrasolar planets through transits. The properties (including structure and composition) and formation histories of many of the newly discovered exoplanets remains an open question. Driven by the search for an Earth-like planet, we have discovered a class of super-Earths or sub-Neptunes which may not fall into either of the traditional categories of terrestrial or gas giant planets, but instead form a new category of ocean planets. In this review paper, I outline the history of this field by looking at major theoretical breakthroughs and outlining recent discoveries of candidate ocean planets.

Programming Template - a useful tool to help me "offload" some of the cognitive load involved in programming. It basically helps me to keep track of what a program is doing and how. If I have many interacting, I then make a collection of them connecting to each other on a bulletin board or blackboard, kinda like in A Beautiful Mind.

About Me

Originally a native of New York City, I have spent time in rural western New York state, assorted parts of Pennsylvania, Tucson AZ, and most recently hail from metro Boston MA.  

I am currently a graduate student in the University of Wyoming Physics & Astronomy department as well as being on leave of absence from a tenured position as Associate Professor of Physics and Astronomy at Quinsigamond Community College in Worcester, MA.  

In my free time (hah!) I play casual video games, listen to sci-fi/fantasy audiobooks, knit, play with my pet bird, and most years I participate in the MIT Mystery Hunt (a team puzzle-solving competition based at MIT, Boston, MA) in a leadership role within the team Grand Unified Theory of Love.
