Supplemental Instruction

Click here for the current Supplemental Instruction schedule. 

As part of the Teaching + Learning Commons, theSupplementaI Instruction (SI) program provides academic support for students who are enrolled in courses that have been challenging to students in the past.  SI Leaders attend all lectures alongside the students who are enrolled in the course, so they always know what is happening in the class. In SI sessions, SI Leaders do not re-lecture or introduce new material. Rather, SI Leaders are trained to maximize active student involvement with the course material and to integratehow-to-learnwithwhat-to-learn; as a result, students who attend SI sessions understand the material better.

List of Courses Suppported by SI

Supplemental Instruction supports these courses:

  • Math 2
  • Math 3C
  • Math 4C
  • Math 10 Series
  • Math 11
  • Math 18
  • Math 20 Series
  • Physics 1A
  • Physics 1B
  • Economics 100A
  • Economics 100B
  • MAE 130B
  • BICD 100 (Pilot: Genetics - Only Dr. Lo's Lecture)

SI Session assist students in:

  • Adjusting quickly to university life (first year and transfer students);
  • Acquiring a clear view of course direction and expectations;
  • Developing their independent learning and study skills to meet the requirements of higher education;
  • Enhancing their understanding of the subject matter of their course through collaborative group discussion;
  • Preparing better for assessed work and examinations by achieving many strategies for success.

SI Leaders during sessions are responsible for:

  1. Creating personalized agendas for each of their SI sessions.
  2. Planning their sessions with a clear focus on group techniques and activities to ensure active discussions rather than re-teaching course content.
  3. Teaching learning skills such as problem solving, revision and exam techniques, or note taking.
  4. Emphasizing conceptual understanding and problem-solving techniques rather than providing specific answers to questions from practice exams, homework, or discussion.
  5. Building and maintaining a sense of community among group members, thereby, creating a fun, informal environment conducive to learning and asking questions.

SI Leaders benefit from their work by:

  1. Helping other students enhance their understanding of science and math subject matter through collaborative group discussion.
  2. Gaining valuable management experience as a facilitator in a peer-based group.
  3. Develop excellent facilitation skills.
  4. Maintain familiarity with course content for tests like the MCAT, DAT and GRE.
  5. Develop strong communication, problem solving, and organizational skills.
  6. Earn hourly pay.

Design Studio Working Hours

A schedule of when the Design Studio is open for general use is posted outside of the door.

In general, it will be open during normal business hours Mon-Fri. The studio can only remain open if there is engineering staff present, and sometimes they get called away to take care of other lab duties. Therefore, sometimes the Design Studio may be closed during normal business hours. 

The studio will remain open during TA office hours, at which times Design Studio assistants have been scheduled to keep the fabrication area open.

ACMS Lab Access

You can find the door code to the ACMS computer labs in EBU2 (203, 205, and 239) by using the on-line Account Lookup link under Tools at Your will need to click on the details button for the course specific account.

OSD Accommodations

Students requesting accommodations for this course due to a disability must provide a current Authorization for Accommodation (AFA) letter issued by the Office for Students with Disabilities (OSD) which is located in University Center 202 behind Center Hall.  Students should present their AFA letters to Faculty (please make arrangements to contact me privately) and to the OSD Liaison (Sandra de Sousa - EBU2-Rm.169) in the department at least two weeks prior to an exam to ensure that accommodations may be arranged.
