2.5.3. Student Performance Standards:

  • For a student to proceed from 100 Level to 200 Level, the student should not fail more than 9 credit units, consequently any student at 100 Level who fails more than 9 credits units at the end of the Academic Session will be advised to withdraw from the Department of Chemical Engineering.
  • From 200-300 Level, a student is expected to pass at least 24 credit units of the total credit units registered for that Academic Session, while for 400 Level, the student must pass at least 12 credit units before he/she can proceed to the next level.
  • Any student who fails to accumulate 24 credit units at the end of any Academic Session except 400 Level or 12 credit units for the 400 Level Academic session shall be on probation.
  • Any student who fails to accumulate up to 12 credit units at the end of any Academic Session except at the 400 Level Academic Session or 6 credit units for the 400 Level Academic Session shall be advised to withdraw from the Department of Chemical Engineering

 

2.5.4.   Course Credit System

The Chemical Engineering programme is run on a modularized system, commonly referred to as Course Unit System. All courses are therefore sub-divided into more or less self-sufficient and logically consistent packages that are taught within a semester and examined at the end of that particular semester. Credit weights should be attached to each course. Onecredit is equivalent to one hour per week per semester of 15 weeks of lectures or 2 hours of tutorials or 3 hours per week of laboratory/studio work per semester of 15 weeks.

 

2.5.5.   Grade Point Average and Cumulative Grade Point Average

Grading of courses shall be done by a combination of percentage marks and letter grades translated into a graduated system of Grade Point Equivalents (GPE).  For the purpose of determining a student’s standing at the end of every semester, the Grade Point Average (GPA) system shall be used.  The GPA is computed by dividing the total number of credit points (TCP) by the total number of units (TNU) for all the courses taken in the semester. The credit point for a course is computed by multiplying the number of units for the course by the Grade Point Equivalent of the marks scored in the course.  Each course shall be graded out of maximum of 100 marks and assigned appropriate GPE as in Table 3.

2.6       EVALUATION OF STUDENTS

2.6.1    Techniques of Student Assessment

(a)  Practical: By the nature of the disciplines in Engineering, laboratory practical are very important in the training of the graduates. To reflect the importance of practical work, a minimum of 9 hours per week (3 credits) is spent on students’ laboratory practical. Furthermore, it is very important to determine performance of the student in the practical component of the programme. To achieve this, all the laboratory practical have been lumped together to form a course which the student must pass. It is expected that the weighting given in the various courses is reflected in number and nature in the design of the experiments.  These practicalfollows the trend in the current development of the programmes.

(b)  Tutorials: There is one hour of tutorial for every four hours of lecture.  Thus, a course of one credit unit should comprise 12 hours of lectures and 3 hours of tutorials.

(c)  Continuous Assessments: Continuous assessment isdone through essays, tests, and practical exercises.

  • Scores from continuous assessment shall normally constitute 30 % of the final marks for courses which are primarily theoretical.
  • For courses which are partly practical and partly theoretical, scores from continuous assessment shall constitute 50% of the final marks.
  • For courses that are entirely practical, continuous assessment shall be based on a student’s practical work or reports and shall constitute 100 % of the final marks.

(d)Examinations:In addition to the continuous assessment, final examinations shall normally be given for every course at the end of each semester. The basis for the final grade shall be as follows:

Final Examination – 70%,

Continuous assessment – 30% (Quizzes, Tutorials, Homework and Tests).             

  • Each course shall normally be completed and examined at the end of the semester in which it is offered.
  • A written examination shall normally last a minimum of one (1) hour for one unit course, two (2) hours for two unit course and three hours for three unit courses.

 

2.6.2    Moderation and Examiners

All question papers from 100 – 400 levels shall be moderated internally. The external examiner shall be used in the final year of the undergraduate programme (500 level) to assess final year courses and projects, and to certify the overall performance of the graduating students. 

 

2.6.3    Board of Examiners

The Head of the Department (HOD) shall be the Chief Examiner. There shall also be an appointed Examination Officer who will be responsible to the HOD. He will be in charge of the conduct of examinations and the recording and return of results for the Department. The Board of Examiners in the Department consist of all Academic staff.

 

2.6.4    Course Advisers

There shall be appointed Course Adviser(s) who will be responsible to the HOD. The Course Adviser shall offer guidance and counselling services to students in their academic, social, personal and vocational life. He/she shall be responsible for the course registration of students, recording and returns of student’s sessional results and other duties as approved by the HOD.

 

2.6.5    SIWES Rating and Assessment

In Engineering Education, industrial attachment is very crucial. The students areto proceed on eight weeks Students’ Work Experience Programme (SWEP) during long vacation at the end of second semester examinations in 100 and 200 levels. At the end of 300 level second semester examinations Students Work Experience Programme (10 weeks – long vacation); Students Industrial Work Experience Scheme (24 weeks, one semester plus long vacation) is for all students at 400 level.

To make the training effective, it is important that the students learn how to operate some of the ordinary machines and tools they will encounter in the industry before they go for the attachment. Therefore they should start with Student Work Experience Programme, which is conducted in the Faculty Workshops, under strict industrial conditions. On successful completion of Students Work Experience Programme, the Students Industrial Work Experience Schemes can be done in industries under strict industrial conditions and supervision.

Normally, industrial attachment should be graded and no student should graduate without passing all the modules of the attachment and this shall be used in degree classification.

3. DEGREE PROGRAMME

3.1       Common Engineering Courses

In the first two years, all students in the Faculty of Engineering shall take common courses. The 200 level courses are foundation Engineering courses designed to expose students to the fundamentals of the Engineering discipline in a broad sense. Students can take 3 credits as electives from their programme of study.

It is believed that exposing engineeringstudents to the various aspects of the discipline in the first two years of their study, equips them with enough knowledge to determine their inclinations in terms of specialization at a later stage.

This view is further strengthened by the fact that an appreciable number of Engineering students have rural backgrounds which limit their perception of Engineering and the sub-disciplines therein.  It is believed that after the second year, the wide Engineering horizon would have been sufficiently illuminated for such students, who are now better placed, to make a choice. In addition, a broad-based programme at these foundation levels becomes an asset to its beneficiaries in the future when they are invariably required to play managerial, supervisory and/or executive roles in Engineering areas that may not be strictly their areas of specialization.

The general courses to be offered by the students in the Faculty of Engineering during their 100 and 200 Levels are presented below, subsequently, by the detailed course description.
