    Participated in an inaugural extended version of the open classroom days. Through this process faculty open their course for visits by other faculty. Such an exchange provides an opportunity to observe how different faculty address similar instructional challenges as well as an opportunity to get feedback on one's own class.

    I opened a total of six sections of my course to visitors and observed BIOLOGY 190H - 01: Quantitative Biology of the Cell which is an honors introductory biology course taught in a team-based learning style.

    Thank you letter for participation

    National Residence-Hall Honorary
    image

    UMass-Amherst campus winner of the "Of The Month Award" for September.

    Nomination: Through his teaching of Physics, he expresses his love and passion for science and the many ways it is changing the world. Sometimes in a big lecture class, it starts to feel like there is less of a connection with the professor, but Professor Toggerson tries his hardest to learn the name of each member of the class and to make the class an interactive experience. Even though team- based learning classes are often disliked by many, Physics is interesting due to the team aspects that lead to a better understanding of many difficult topics. I look forward to attending the class three times a week due to the intriguing demonstrations and collaborative activities. When we complete team projects, Professor Toggerson plays an active role in assisting the class with anything that may come up. He is always prepared for class and his positive attitude makes the class more enjoyable overall. I appreciate how much he cares about his students both in and out of the classroom. He also sent out an email in which he provided academic resources and more importantly mental health resources on campus. These issues are often overlooked by many and Professor Toggerson cares for the well being of his students. Overall, I think Professor Toggerson is a tremendously hardworking person and I think that he should be recognized for the awesome job he does each day.

    Teaching for Inclusiveness, Diversity, and Equity (TIDE) Ambassadors
    image

    A $1500 grant from the UMass, Amherst Institute for Teaching Excellence and Faculty Development.

    TIDE Ambassadors explore how they can enhance students’ learning and academic success across cultural, social, and learning differences by adopting a strength-based, inclusive, and equitable approach to teaching and learning grounded in the value of diversity. The program acknowledges the potential of faculty functioning as catalysts for change through intensive professional development of faculty across disciplines and career stages.

    TIDE Ambassadors take what they learn from their experiences with the fellowship program and develop a project through which they share their growing expertise and contribute to the dialogue about and practice of teaching for inclusiveness, diversity, and equity at the departmental, school/college, or campus-wide levels.

    While white cis-gendered men are actually not a majority in my physics 131 and 132 courses, they do volunteer to contribute more to class discussions than other groups. Moreover, I have definitely observed, both as a practicing physicist and as a physics instructor in a teambased learning (TBL) environment, an undervaluing of the contributions of minority groups. As part of this fellowship, I want to explore ways to minimize and mitigate these effects.

    Another topic I would like to explore is equity with regard to disability particularly in my TBL courses. Many of the suggestions and accommodation requests from our Disability Services offce are tailored to a typical lecture-style course and do not really apply to TBL. For example, a common accommodation is to provide notes before class. However, in a TBL environment, there is only a small amount of lecture and students are spending over half of the class-time working on problems in teams. What accommodations are needed for this environment? How can I structure the course in a way that uses the principles of universal design and minimizes the need for accommodations?

    Finally, the issue of diversity came up several times in the first iteration of physics 390T. As part of that course, we discuss issues such as stereotype threat and soloing with regards to team formation and dynamics within a TBL classroom. The format of these discussions stemmed from readings from the physics education literature. Some students reacted to these ideas with skepticism. Through this fellowship, I would hope to learn new ways of exploring these ideas and facilitating better discussions with my students.

    $500 Award

    Innovation Fellows are faculty who participate in the Innovate@ Symposia that are offered throughout the year. Launched in summer 2016, these symposia are unique workshops that allow faculty to explore different ways of using a wide spectrum of instructional tools and then plan a targeted implementation during the academic year. Faculty then become part of the Innovation Fellow think tank and are the front line for discussing new instructional innovations and for creating a roadmap for sustainable innovations at UMass Amherst. These faculty are also willing to be contacted by faculty throughout the year to talk about instructional technologies and to promote their use in teaching and research.

    My innovation is using social media tools such as twitter to provide an additional way for students to engage with large lecture classes.

    Physics 131

    Reform of the first semester of algebra-based introductory physics.

    Physics 131 is the first semester of introductory algebra-based physics. The students who take this course are predominately life-science majors with a significant contribution of students from the UMass Building and Construction Technology program.

    While Physics 131 has always been at the leading edge of implementing research-based teaching at UMass, beginning in the Fall 2015 semester, a concerted effort was made to convert all sections of this course away from a lecture-based course into a TBL course based upon the literature. By the Spring 2016 semester, a strong foundation for the course had emerged which is providing the foundation for future development.

    Physics 132

    Reform of the second semester of algebra-based introductory physics.

    Physics 132 is the second semester of introductory algebra-based physics. The students who take this course are predominately life-science majors with a significant contribution of students from the UMass Building and Construction Technology program.

    P132 is the second course in the introductory physics for life-science sequence. While we are in the process of figuring out the logistics of how to make this course TBL, this course is, unlike P131, currently being taught in a large lecture hall with an independent lab section. I am currently exploring the best active learning techniques for this space that are consistent with our goals. One idea being explored is the use of Twitter to provide a forum for back-channel discussion within the large lecture hall. You can see the course Twitter page from the Spring 2017 semester at http://twitter.com/UmassP132. Currently, this course is centered on the big question of “What is light? What is an electron?” and introduces quantum mechanics, optics, and electricity and magnetism.

    Graduate Teaching Assistant Training Program

    1-credit seminar to be required for all incoming graduate students to be offered in the fall semester to help them with their transitions to becoming graduate students and to provide them the skills needed to be effective TAs.

    Our primary goals for this seminar are:

    1. Most of what our TAs do is facilitation of groups working in teams (Team-Based Courses, Labs, Office Hours). Thus, we want our TAs to be effective in facilitating students working in teams to solve problems.
    2. We want a “professionalization” of our GTA program which includes (but is not limited to) an improvement of GTA self identity and a development of an explicit awareness of the transferrable skills that being a GTA provides. Furthermore, we feel that the GTA seminar would provide an excellent context for the exposure to issues of diversity. Many of these issues were addressed in the report provided by the AQAD committee.
    3. Improve faculty support for a robust GTA program (as opposed to disparate TAs assigned to faculty) for stability of the program over time.
    By addressing these goals in the seminar, we will allow the weekly TA meetings for the various courses to be more productive and focused on the specific challenges associated with each course.

    Summer College Particle Physics

    A two-week summer program for high-school arranged through the UMass Amherst Commonwealth honors college

    During this two-week particle physics program, motivated high-school students have the opportunity to explore the exciting world of electrons, particles of light, the famous Higgs boson, and more. They learn about the fundamental forces and conservation laws that govern this world of particles, and, by extension, our world. In addition to the underlying physics concepts, participants have a hands-on opportunity to learn about how modern science is done by actually doing it. Participants work in teams analyzing real data from modern particle experiments such as the CMS experiment at CERN as part of a two-week project. In this project, participants will decide what particle to focus on and, as part of a team, figure out how to separate collisions in which your particle is produced from background "look-alike" events. The skills you will develop, such as statistical analysis, are used not only by particle physics, but also by professionals in astronomy, genetics, epidemiology, and the new field of data science.

    There are two materials available for this class, please feel free to use either of them with attribution:

    Course Wish-lists

    Courses I'd Love to Teach

    Below are some courses that I always thought would be fun to teach. If you are interested in one, contact me!

    General-Education Modern Physics
    Modern physics is sexy! Frequently in the news, I have experienced a keen interest in this topic from students. I would love to teach a general education course similar to Introductory Astronomy courses that are commonly offered as part of general education programs in the U.S. Topics would include the particle content of the Standard Model, and ideas from Special Relativity.

    The Martian by Andy Weir
    The upcoming movie based on this book will generate great excitement. The science in it is rather accurate and covers a bunch of typical topics from an intro physics course: Unit conversion, kinematics, basic horticulture, Newton's Laws and gravitation, conservation of momentum (both translational and rotational), statics, mechanical advantages basic electronics, basic chemistry, the Laws of Thermodynamics, and more. This would be a great hook for another general-education physics course.

    Data Analysis for Upper Division Physics Majors
    The plethora of publicly available data on the internet allows for neat student project-based learning about how to analyze real data. Topics would include Monte Carlo methods, machine learning, plotting, and more. Moreover, such a course would help students expand their programming skills beyond what is typically taught in into programming courses for physics majors.

NerdNite: How to Not-Explain Things Well

B. Toggerson
Presentation December 2018 NerdNite, The Duce, Northampton MA

Abstract

How can we apply lessons about how people actually learn from educational psychology and neurology to teaching physics effectively? The standard lecture is definitely the most familiar technique, but is it the most effective? Are there other things that we as instructors can do that would work better? How do we define "better?" In this talk for the public, I explore some of the principles of effective teaching. While I am a physics teacher, and therefore speak within that context, most of these techniques can be applied to other disciplines as well. I then go on to explore the impacts of these techniques on the self-efficacy, or belief in one's ability to learn, for introductory physics for life-science students.

Exposing Physics Majors to Education while Supporting Studio-Style Courses

B. Toggerson
Presentation AAPT Summer 2018 Meeting, Washington DC

Abstract

Many departments have few formalized opportunities for physics majors to explore education principles within physics departments. Moreover, teaching a 100-student course in a team-based format as in Michaelsen et al often requires significant in-classroom assistants. At UMass-Amherst, we have been developing a course to meet both of these needs. In our course, students engage with modern PER literature and get hands-on practical experience in a studio-style classroom under the mentorship of one of our department’s lecturers. Simultaneously, the students in this course provide the in-classroom support needed for the first semester of our introductory physics for life sciences course. We will present some of the key features of our course, in particular how course assignments both help the department achieve its teaching goals as well as allow students develop real-world products they can use in future job searches.

Application of Team-Based Learning to a First Semester IPLS Course, Physics 131: Forces, Energy Entropy

Abstract

We present the current status of an effort at UMass, Amherst to transition the first semester of our large IPLS course to a team-based learning format following Michaelsen et al while simultaneously adjusting the topics and skills covered to apply to our population. We will present our motivations for the transition, key features of our course’s structure, and an overview of the largest departures in content from a typical algebra-based introductory course. We will also discuss new developments towards a dedicated free and open-source textbook for our course based upon the OpenStax College Physics text.

Transitioning a 300-person IPLS Course to Team-Based Learning, Physics 132: What is Light? What is an Electron?

B. Toggerson
Poster AAPT Summer 2018 Meeting, Washington DC

Abstract

Over the past years, we at UMass-Amherst have been transitioning six 100-student sections of a first-semester introductory physics for life science (IPLS) course into a team-based (TBL) model following Michaelsen et al. Here we present an overview of our first efforts to teach the second semester of the sequence in the same style. Due to institutional constraints, the second semester of the sequence has 300 students per section and is taught in a traditional lecture hall. A discussion of how we handled some of the logistical challenges of teaching in a TBL mode in this space will be touched upon along with a discussion of the particular IPLS features and some notes on future plans.

Physics 131: Forces, Energy and Entropy

Brokk Toggerson, David Nguyen
Book University of Massachusetts Amherst Libraries | August 31, 2017 | ISBN-10: 1-945764-03-1
image

An introductory textbook for Physics 131 at University of Massachusetts Amherst compiled from OpenStax College Physics.

Physics 131 at UMass-Amherst is specifically tailored to life-science students. However, most algebra-based introductory textbooks contain essentially the same content as their calculus-based counterparts targeted towards an audience of engineers. This book is based upon the OpenStax College Physics textbook and adds materials from other creative commons sources such as the University of Maryland NEXUS Project Wikibook as well as custom-written content.

A few of the most significant differences from a standard textbook include:

  • The removal of the standard kinematic equations in favor of determining the motion of objects through the writing of simulations.
  • An emphasis on the categorization of forces based upon different properties.
  • In the unit on energy, an explicit effort to connect material to topics discussed in introductory chemistry
  • A complete unit on the statistical interpretation of entropy.

Search for direct slepton and gaugino production in final states with two leptons and missing transverse momentum with the ATLAS detector in pp collisions at sqrt(s) = 7TeV

The ATLAS Collaboration
Journal Papers Phys. Lett., B718:879-901, 2013.

Abstract

A search for the electroweak pair production of charged sleptons and weak gauginos decaying into final states with two leptons is performed using 4.7 fb-1 of proton-proton collision data at sqrt(s)=7 TeV recorded with the ATLAS experiment at the Large Hadron Collider. No significant excesses are observed with respect to the prediction from Standard Model processes. In the scenario of direct slepton production, if the sleptons decay directly into the lightest neutralino, left-handed slepton masses between 85 and 195 GeV are excluded at 95% confidence level for a 20 GeV neutralino. Chargino masses between 110 and 340 GeV are excluded in the scenario of direct production of wino-like chargino pairs decaying into the lightest neutralino via an intermediate on-shell charged slepton for a 10 GeV neutralino. The results are also interpreted in the framework of the phenomenological minimal supersymmetric Standard Model.

Search for Direct Gaugino Production Decaying to Two Leptons and Missing Transverse Momentum at ATLAS with sqrt(s) = 7 TeV

B. Toggerson
Dissertation University of California, Irvine 2012

Abstract

A search for the electroweak production of gauginos decaying into two leptons and missing transverse momentum, [special characters omitted], is presented using pp collisions at sqrt(s) = 7 TeV produced by the LHC and recorded by the ATLAS detector corresponding to an integrated luminosity of 4.7 fb?1. Standard Model backgrounds are estimated using a combination of semi-data-driven techniques where possible, and Monte Carlo simulation. No significant excess in data with respect to the Standard Model prediction is observed in any of the four signal regions: opposite-sign dileptons with a jet veto and missing transverse energy (MET), same-sign dileptons with a jet veto and MET, opposite-sign dileptons in association with jets, or a signal region requiring opposite sign dileptons and using kinematic properties of the event to remove top anti-top and WW backgrounds. In addition to model-independent limits, limits are set in both simplified models and in the context of the phenomenological Minimally Supersymmetric Standard Model. Using the simplified model paradigm, wino-based charginos, decaying through an intermediate on-shell slepton or sneutrino to a stable 10 GeV neutralino, are excluded for chargino masses between 110 and 340 GeV. For the case of associatively produced mass-degenerate charginos and neutralinos both decaying via on-shell sleptons or sneutrinos to stable 10 GeV neutralinos, the chargino and neutralino masses of 80-260 GeV are excluded.

Abstract

Results of three searches are presented for the production of supersymmetric particles decaying into final states with missing transverse momentum and exactly two isolated leptons, e or mu. The analysis uses a data sample collected during the first half of 2011 that corresponds to a total integrated luminosity of 1 fb^-1 of sqrt{s} = 7 TeV proton-proton collisions recorded with the ATLAS detector at the Large Hadron Collider. Opposite-sign and same-sign dilepton events are separately studied, with no deviations from the Standard Model expectation observed. Additionally, in opposite- sign events, a search is made for an excess of same-flavour over different-flavour lepton pairs. Effective production cross sections in excess of 9.9 fb for opposite-sign events containing supersymmetric particles with missing transverse momentum greater than 250 GeV are excluded at 95% CL. For same-sign events containing supersymmetric particles with missing transverse momentum greater than 100 GeV, effective production cross sections in excess of 14.8 fb are excluded at 95% CL. The latter limit is interpreted in a simplified weak gaugino production model excluding chargino masses up to 200 GeV.

Results are presented of searches for the production of supersymmetric particles decaying into final states with missing transverse momentum and exactly two isolated leptons in sqrt(s)=7 TeV proton-proton collisions at the Large Hadron Collider. Search strategies requiring lepton pairs with identical sign or opposite sign electric charges are described. In a data sample corresponding to an integrated luminosity of 35 pb-1 collected with the ATLAS detector, no significant excesses are observed. Based on specific benchmark models, limits are placed on the squark mass between 450 and 690 GeV for squarks approximately degenerate in mass with gluinos, depending on the supersymmetric mass hierarchy considered.

Measurement of the top quark-pair production cross section with ATLAS in pp collisions at sqrt(s) = 7 TeV

The ATLAS Collaboration
Journal Articles EPJC, 71:1577, 2011.

Abstract

A measurement of the production cross-section for top quark pairs (ttbar) in pp collisions at sqrt(s}=7 TeV is presented using data recorded with the ATLAS detector at the Large Hadron Collider. Events are selected in two different topologies: single lepton (electron e or muon ?) with large missing transverse energy and at least four jets, and dilepton (e e, mu mu or e mu) with large missing transverse energy and at least two jets. In a data sample of 2.9 pb-1, 37 candidate events are observed in the single-lepton topology and 9 events in the dilepton topology. The corresponding expected backgrounds from non-ttbar Standard Model processes are estimated using data-driven methods and determined to be 12.2 +/- 3.9 events and 2.5 +/- 0.6 events, respectively. The kinematic properties of the selected events are consistent with SM ttbar production. The inclusive top quark pair production cross-section is measured to be $\sigma_ttbar=145 \pm 31 ^{+42}_{-27}$ pb where the first uncertainty is statistical and the second systematic. The measurement agrees with perturbative QCD calculations.

Cathode Strip Chambers in ATLAS: Installation, Commissioning and in Situ Performance.

T. Argyropoulos et al.
Conference Papers Nuclear Science Symposium Conference Record, 2008. NSS '08. IEEE

Abstract

The Muon Spectrometer of the ATLAS detector at the LHC is designed to provide high quality stand-alone muon identification, momentum measurement and trigger capabilities with high pseudorapidity coverage. Precision tracking at the inner-most station in the high pseudorapidity regions, 2.0 ? |?| ? 2:7, is performed by 16 four-layered Cathode Strip Chambers on each end-cap. These are multi-wire proportional chambers with segmented cathodes providing excellent spatial resolution and high counting rate capability. The second cathode of each layer is coarsely segmented, providing the transverse coordinate. The detector level performance of the system is presented. The installation and commissioning effort for the Cathode Strip Chambers is described. Finally, the in situ performance is briefly discussed.

Onset of space charge effects in liquid argon ionization chambers

B. Toggerson et al.
Journal Articles Nuclear Inst. and Methods A, 608(2), September 2009.

Abstract

Using a thin-gap liquid argon ionization chamber and Strontium-90 beta sources we have measured ionization currents over a wide range of gap potentials. These precision "HV plateau curves" advance the understanding of liquid argon sampling calorimeter signals, particularly at high ionization rates. The order of magnitude differences in the activities of the beta sources allow us to estimate where the ionization chamber is driven into the space-charge dominated regime.

    Letters of reference

    What you need to know before you ask for a letter of reference from me.

    1. First think to yourself, "Will Dr. Toggerson be able to recall my face when he sees my name?" Remember, I have over 300 students a semester. While, I can write a letter without this criterion being met, it will not be a very good letter, and probably will not help your case.
    2. You should have earned a high B in my class in order to get a letter. Exceptions to this rule will be made if you have demonstrated exceptional improvement over the course of the semester.
    3. Provide a CV or resume. This should describe the relevant courses you took, the research projects you have worked on, any honors, and relevant work experience.
    4. If you have a personal statement, please send me that as well. Such statements can be helpful in making the letter more personal. However, don't write a personal statement just for me.
    5. If more than one reference is needed, please provide me a list of all recipients and due dates
    6. Be aware of deadlines. Don't annoy me (the person you are asking for comments on your work ethic!) by handing me requests due the following day unless you can convince me that there is a really good reason for the late notice!
    7. Please follow up with me. I get many emails, and sometimes, I may put your request on the back burner in order to deal with more urgent matters. Silence doesn't mean no, silence means I forgot. It is up to you to follow up.
    8. Speaking of following up, if you give me a request months out, you may want to follow up as the deadline gets closer.
    9. I will let you know when the letter has been sent.
    10. This item is not specific to me, but good advice in general; if someone of whom you have asked for a letter says, "you must have someone who could write you a better letter." Take the hint! You don't want someone writting you a bad letter.
    11. I will ask you to meet one-on-one. We will chat so that I can get to know you better.

    Physics Study Techniques

    A collection of physics study techniques from current physicists and engineers.

    I asked some friends and colleagues of mine who are all now physicists or engineers, "How do you study physics?" Here are their responses:

    Me

    I would go to lecture and take detailed notes. After lecture I would begin working on the homework and do as much as possible on my own. Afterwards, I would contact a friend or two of mine and set up a homework session where we would go through our solutions. Sometimes in the course of trying our solutions to each other we would find a mistake in our work. If no one understood the problem, then we would work on it together. These were the problems where we probably learned the most; we would explain ideas to each other and explore the concepts involved. If we got stuck, we would go ask the instructor for help.

    In preparing for exams, I would go through the text and combine my class notes and the text into an outline or map of the concepts. These outlines definitely found use later in making studying for the final exam much more efficient. After outlining, I would work practice problems. Usually these problems were done in a group, as I find explaining what I did to others to be very beneficial.

    MW (physicist in industry)

    I did my best when I did lots of practice problems that provided di erent examples of using the same concepts. Using the same concepts in di erent ways to solve di erent problems helps to abolish the idea that you can just plug and chug without thinking about the real problem at hand.

    JS (engineer)

    Focus on concept based questions. I've found a lot of engineers get by on their math skills alone and couldn't answer the simplest of conceptual questions. I've also found drop outs who could have made great engineers, but they got tripped up trying to understand and didn't get the emphasis on understanding the material they needed since it was all about solving the problem.

    Also, make sure your algebra skills are like second nature. That way you are not thinking about algebra, you are focused on the concepts and any new mathematics. I thought I understood algebra, I got a good grade in it, but I had trouble doing it at the level needed at first.

    RPM (astronomy Ph.D.)

    Lots and lots of practice problems, even ones I've done before. Not just doing them, either, but making sure I understand why I'm doing what I'm doing. Also, I usually go through my notes/the text book and summarize key points, relationships, and equations. For the equations, I make sure that I know what they do and how to use them (practice problems help with this step). It's a long process that requires at least two days, sometimes more depending on what I'm studying for and how much material there is.

    CBL (physicist in industry)

    Understand the di erence between the mathematical framework and the physical model. What are the physical concepts and how is it written down mathematically? Physics and mathematics is so intertwined that it can be hard . . . to see what is what. Learn how to read formulas; what does each symbol stand for and what is it purpose? Learn how to write formulas: "If I want to express this physical concept mathematically, how would I do it?" Always read the units in an equation, so that you know what the core quantity is flowing between all the separate components of the equation. To know what is flowing between everything is essential for the understanding of an equation. To know what is fl owing is also to know what is conserved. In the end we are all plumbers.
