TailorEd Research Project

Overview

Our study used automated aerial photography to document the instructional formats used in 74 courses taught in humanities, social sciences, engineering, and business disciplines in 12 active learning and 2 traditional (control) classrooms. We used the machine learning tools available in Matlab to analyze the photos to identify instances of lecture format, large group discussion, small group discussion, approximating different active learning formats. The next stage of the project will cross-reference these breakdowns of the kinds of pedagogical techniques used and their proportions, and correlate them to student learning outcomes (measured by grades), broken down by student demographic factors.

About

The TailorEd Study looks at the relationships between

  • classroom design (for example, mobile vs. stationary desks),
  • teaching formats (lecture, discussion, small group work, use of classroom technology, etc), and
  • student performance (measured by grades), and student characteristics (race, gender, major, etc).
Its goal is to test the claims made in learning space design researchers that active learning formats (such as discussion and small group work) improve learning, especially for students marginalized in educational settings due to their gender, race, and other identity characteristics. Faculty and students teaching/taking classes included receive an email notifying them of inclusion of their class in the study, which directs them to this webpage, that provides information about the study, explains where to direct questions, and informs about how to opt out of the study. There are also signs posted in all study classrooms notifying faculty and students that the classroom is part of the TailorEd Study. For frequently-asked questions about the study, see our FAQ page


TailorEd in Course Hero's Education Summit 2020

In this session we will present TailorEd: A custom image recognition neural network applied to imagery of select classroom environments coupled with student demographic and grade data in a study of the effects of pedagogical practices and classroom technologies on learning. We will start with the motivation behind this project and explain how we have gathered our data, guide the attendees through a human qualitative data coding practice via a hands on exercise, introduce our Classroom Configuration Identifier (CCID) image classifier neural network via a live demo, share our preliminary results and explain our data modeling procedure, demo our resulting web tool for educators, and end by delineating the project’s future steps.


Study Procedures

The study uses aerial classroom photography at 30-second intervals to capture classroom activities in real time. Researchers will then run these photos through a machine learning algorithm to categorize the activities depicted in order to determine the proportion of the class allocated to different activities. These course "pedagogical profiles" will be compared to student learning outcomes (in the form of grades) to identify relationships between different types and distributions of classroom activities and student learning, differentiated by

  • course factors (such as discipline and level),
  • classroom characteristics (such as the presence/absence of mobile furniture, writable walls, multiple projectors, and smartboards), and
  • student information (demographics, course grade and GPA, etc).



Confidentiality

Reports/publications based on this study will focus on aggregate findings across all courses included in the study, not on individual courses, faculty, or students. Faculty will not be identified at all, and students/student information will be identified using a unique identifier (NOT their student ID#) generated for the purpose of this study only. There is some small risk of identifiability in the photos as sample photos illustrate, people who know the individuals depicted may be able to recognize them. To mitigate this, individuals included in classroom photographs will never be identified in any part of this study, limiting the risk of identifiability more broadly. The photos also depict a "public" event (class meetings), and therefore do not contain sensitive or compromising information.

All records and research materials associated with this study will be kept in a secure location (password-protected computer/cloud backup). Only members of the research team will have access to project records and research materials.


Participants' Rights

Participation in this study is voluntary and won't affect your employment or performance review at Santa Clara University. You are free to opt out of the study at any time and to see research materials in which you are included (photos or reports on the study). If any member of the class (faculty or student) objects at any time to participating in the study, the course will be removed from the study and all data associated with that course will be permanently deleted.

Frequently Asked Questions

TailorEd takes only still photographs at 30-second intervals. We do not record any video or audio. If a class uses lecture capture or other classroom recording technologies, the study does not have access to those recordings, only to our own photographs.

No. Students and faculty are welcome to opt out of the study at any time, without any kind of penalty. To opt out, refer to the opt-out link provided in your study notification email, which has the subject line "Classroom Study Notification".

If anyone -- a student or a faculty member -- opts out of the study, their class will be removed from the study. If the class hasn't met yet, no data will be collected. If the quarter has already started and images have already been captured, we will stop data collection in that class and delete all existing data.

Nothing. If you're no longer taking the class, you don't need to do anything, because no data involving you will be collected. Getting the study notification email was an error; it does not mean you're still enrolled or that you need to do anything to change or update your schedule. Sorry for the confusion!

Because students can add/drop classes until the end of Week 1, class rosters -- which we use to send out study notification emails -- are not finalized until Week 2. This ensures that we don't send emails to students who are no longer enrolled in study classes and that we don't miss any enrolled students who add the class late. (for study opt-outs that happen after the quarter has begun and data collection has begun, see "General FAQs" section)

Please notify one of the PIs (Julia Voss, jvoss@scu.edu , 408-554-2715 ; Navid Shaghaghi, nshaghaghi@scu.edu , 408-554-4179 ) so we can update the list of classes included in the study.

The ways in which faculty are designing courses that differ from Santa Clara's 100% in-person format is also of interest to the study, so we hope you'll agree to keep classes like this in the study.

You aren't obligated to tell them anything; the study's methods are designed so as not to impose on faculty or take up valuable class time. Students receive their own study email notification (sent during Week 2, after the add/drop date passes to ensure that all students receive the message). You're welcome to discuss the study with your students, however, if you like, and to direct any questions that come up to the study PIs Julia Voss ( jvoss@scu.edu , 408-554-2715 ) and Navid Shaghaghi ( nshaghaghi@scu.edu , 408-554-4179 ).

We're working on a data visualization report to offer participating faculty showing a breakdown of in-class activities across meeting days. Stay tuned, and if you have ideas and/or requests about this, please share them with study PIs Julia Voss ( jvoss@scu.edu , 408-554-2715 ) and Navid Shaghaghi ( nshaghaghi@scu.edu , 408-554-4179 ).
