Teaching Assistant information

What is a teaching assistant?

Teaching Assistants (TAs) are individuals who support teachers in the classroom, helping with instructional responsibilities, classroom management, and student engagement. Their duties may include assisting with lesson preparation, working with small groups of students, grading assignments, and providing additional support to students who need extra help. TAs play a crucial role in ensuring that lessons run smoothly and that students receive the attention they need to succeed. They are commonly found in schools, colleges, and universities, working under the supervision of a lead teacher or professor.

What are the key skills and qualifications needed to thrive as a teaching assistant, and why are they important?

To thrive as a Teaching Assistant, you need a solid understanding of educational principles, classroom management, and typically a relevant degree or certification such as a paraprofessional license. Familiarity with learning management systems (LMS), educational software, and basic office technology is often required. Strong communication, patience, and adaptability are essential soft skills for supporting diverse student needs and collaborating with teachers. These skills ensure effective learning support, positive classroom environments, and successful student outcomes.

What does a teaching assistant do?

Teaching Assistants generally work with licensed teachers in school settings to help give students attention and instruction. Their responsibilities may include reinforcing lessons, reviewing materials with students, helping teachers keep records like calculating grades or taking attendance, helping prepare the lessons, and supervising students in and outside of the classroom. Some Teaching Assistants may also be responsible for helping students with special needs, as their presence may allow for additional attention. Teaching Assistants may also be there to help students use programs or software, partake in extracurricular or elective courses, or supervise them as they do their activities. A Teaching Assistant can also be a graduate student who aides their professor during class.

What are some common challenges teaching assistants face when supporting diverse classrooms, and how can they effectively address them?

Teaching Assistants often work in classrooms with students of varying abilities, backgrounds, and learning styles, which can present challenges in providing individualized support. To address these, TAs can collaborate closely with lead teachers to understand each student's needs, use differentiated instruction techniques, and remain flexible in their approach. Building strong relationships with students and maintaining open communication with educators help TAs create an inclusive environment where all students can thrive.

What qualifications do you need as a teaching assistant?

A teaching assistant typically needs a high school diploma or equivalent, with some roles requiring postsecondary education or relevant coursework.

General Purpose

The School of Computer Science is the second largest academic unit within the College of Computational, Mathematical and Physical Sciences and currently consists of 28 tenured or tenure-tracked faculty members, 10 full-time, and 1 TFT staff positions. Several faculty and staff positions are dedicated to the School's graduate-level Cybersecurity course-based Master's programs (MCTI and MCLC). We currently have over 1200 students enrolled in our undergraduate programs, ~110 thesis and course-based graduate students. We also work with 1000-1500 additional U of G undergraduate students each year in general computing service courses and provide a wide range of services to support these activities.

SoCS has a long tradition of high-quality experiential learning in our Bachelor of Computing (B.Comp) degree programs. Thus, hands-on programming, software engineering, and computing infrastructure are an essential part of our academic programs. This position aims to directly support the delivery and coordination of course infrastructure, assessment systems, and operational tools that enable technically rigorous student learning experiences.

Duties and Responsibilites

The primary responsibilities of the Instructional Lab Assistant (IA) are to work directly with instructors and technical staff to support the provisioning of instruction using TAs and departmental infrastructure that are central to delivering undergraduate Computer Science and Software Engineering courses. They are an integral member of the instructional support team, collaborating with faculty, teaching assistants (TAs), and systems analysts to ensure computing tools, environments, workflows and presented labs meet instructional requirements.

The IA plays a central role in supporting SoCS's large courses, which enroll 300-600 students per lecture section and require coordination across dozens of lab and tutorial sections. These courses often rely on complex software tools (version control, automated grading, containerized environments), large-scale lab exam infrastructure, and the coordination of the efforts of multiple teaching assistants.

Instructors and TAs rely on the IA for assistance with the deployment of autograders, setup of course-specific tooling, and coordination of TA logistics and teaching delivery. The IA develops and maintains operational documentation, assists with the delivery and invigilation of makeup exams, assists with the coordination and teaching consistency of the potentially large groups of TAs across courses and ensures that infrastructure for assessment delivery and academic integrity tools is properly configured and supported.

The IA liaises with Student Accessibility Services (SAS) on behalf of faculty to implement infrastructure accommodations and support AODA compliance. They also monitor tool performance and recommend continuous improvements to ensure reliable and equitable access to course infrastructure.  The IA must remain current with technical tools and pedagogical technologies and support the instructional team in creating a responsive, inclusive, and high-quality experiential learning experience for students.

Requirements

Undergraduate Degree in Computer Science or closely related field. 

Minimum 2 years experience.  Previous experience as a teacher or teaching assistant in a higher-education institution preferred.
