Examinations:

Examinations will combine true/false, multiple-choice, short and long answer questions. Some math calculations related to test data will also be included. Unless expressly otherwise indicated, the use of electronic devices is restricted during examinations. Only approved non-programmable calculators are permitted. The exams will cover material from assigned readings, specified

sections of the textbook and content from both lectures and labs. Sample exam questions will be provided on eClass at least one week in advance of the exams.

 The midterm exam will be 45 minutes long, conducted in class and will cover the course content to the date of the exam.

 The final exam will be 120 minutes long and cover the whole course.

Policy on missed exams:

Excused absences are not automatic, and, in the case of term work or midterm exams, are at the discretion of the instructor. Instructors may request supporting documentation from students to support the request.

Midterm exam:

If a student misses the midterm exam for a valid reason, such as serious illness or bereavement, a

Final Exam:

Instructors can neither give permission to a student to miss the final exam nor grant a request for a deferred final exam. The decision to allow a deferred final exam can only be granted by your Faculty. The University policy on deferred exams can be found in Section 23.3 (2) of the University Calendar. It includes specific instructions on how to obtain a deferral.

Labs:

Laboratory attendance is mandatory.

 There are five distinct labs to complete as indicated in the Course Schedule.

 Laboratory topics incorporate lecture material, but do not mirror the lecture outline exactly.

 Laboratory procedures and activities are described fully in the Student Laboratory Manual provided in class. It is necessary to read the test methods in advance of each lab period.

The test methods are available on-line. Pre-lab questions must also be completed for the start of each new lab.

 Labs 1 through 4 involve textile testing activities and the completion of the appropriate sections of the Student Laboratory Manual. These sections are to be submitted for marking one week after the completion of the lab.

 Students will work with a partner for most of the lab activities, but are expected to complete the lab questions independently. Matching answers submitted by lab partners will not be graded.

 For Lab 5, in addition to performing the testing activities, each student will complete a formal test report of their own design, following the instructions in the Student Laboratory Manual.

 Remember to keep a copy of your final lab report as you may wish to include it in your portfolio for HECOL 408 in your final year.

Lecture and Lab Policy:

 Food and drink are not permitted in the laboratory rooms.

 Cell phones must be turned off during the lecture and lab time.

 Audio or video recording, digital or otherwise, of lectures or labs by students is allowed only with the prior written consent of the instructor or as a part of an approved

accommodation plan.

 Student or instructor content, digital or otherwise, created and/or used within the context of the course is to be used solely for personal study, and is not to be used or distributed for any other purpose without prior written consent from the content author(s).

Policy on late assignments:

 Lab exercises and reports received after 6:00 pm on the due date will not be graded, and will receive a raw score of zero, unless the student can demonstrate a valid reason for the late completion such as a serious illness or bereavement.

Grading system:

The evaluation of examinations and lab exercises will be recorded as raw marks throughout the term. The final cumulative score out of 100 points will be translated into a letter grade based on the university four-point grading system (see below). Assignment of final grades is based on a combination of absolute achievement and relative performance in this course.

Excellent: A+ 4.0 Outstanding: The student has demonstrated an extraordinary grasp of the course content and performance reflects creativity and innovation, in addition to a high level of analytical ability.

A 4.0 Excellent: The student has demonstrated superior understanding of the course content and a high level of analytical ability.

A- 3.7 Student has demonstrated superior understanding of the course content, but has not shown the same level of analytical ability as students receiving an A.

Good: B+ 3.3 The student has demonstrated a sound understanding of course material, with superior understanding being evident in some topics.

B 3.0 The student has demonstrated a uniformly sound understanding of course material.

B- 2.7 The student has demonstrated a generally sound understanding of course material, but there are some areas in which depth of

understanding is limited.

Satisfactory: C+ 2.3 The student has demonstrated adequate awareness of course content with sound understanding of some topics.

C 2.0 The student has demonstrated adequate awareness of all of the central dimensions of the course.

C- 1.7 The student has demonstrated adequate awareness of most central dimensions of the course, but lacks knowledge of one or two topics.

Poor: D+ 1.3 The student has demonstrated a lack of knowledge in one or more of the central dimensions of the course, and has very superficial understanding of most topics.

Minimal Pass: D 1.0 The student’s performance is only minimally acceptable due to a lack of understanding of several central dimensions of course content.

Fail: F

F(R)*

0.0 The student has demonstrated a lack of knowledge of most of the course content.

*F(R) denotes eligibility of a student to apply for a re-examination in a course

Code of student behaviour:
