Department of Chemistry

 

ABOUT THE DEPARTMENT

The Department is relatively young. Academic work started in full swing in 1975 and the foundation students of that then were graduated in 1979. Many of the graduates since then have found employment in practically every thinkable, chemically oriented area, industry; academia, research and even some are gainfully self-employed. Many have also obtained postgraduate qualifications in chemistry and related disciplines. On the staff list, the department has had representation from practically every continent of the world, although many of such persons, in the meantime, have left for greener pastures elsewhere.

The general philosophy and objectives of the programme are:

  1. to create the awareness of the dynamic nature of knowledge in relation to evolving problems of national development and growth, within the context of globalization;
  2. To develop Intellectual and professional skills to function independently or in a team environment with a problem-solving orientation.

Specific Objectives of the programme are:

Students obtaining a B.Sc degree in Pure or Industrial Chemistry should have upon graduation:

 

  1. The basic analytical and technical skills to work effectively in the various fields of chemistry.
  2. The ability to perform accurate quantitative measurements with an understanding of the theory and use of contemporary chemical instrumentation, interpret experimental results, perform calculations on these results and draw reasonable, accurate conclusions.
  3. The ability to synthesize, separate and characterize compounds using published reactions, protocols, standard laboratory equipment, and modern instrumentation.
  4. The ability to use information technology tools such as the Internet and computer-based literature searches as well as printed literature resources to locate and retrieve scientific information needed for laboratory or theoretical work.
  5. The ability to present scientific and technical information resulting from laboratory experiments in both written and oral formats.
  6. Knowledge and understanding of the issues of safety regulations, ethics and societal issues in the use of chemicals in their laboratory work.
  7. The ability and skill to compete with their contemporaries from other higher institutions  

                   for job placements.

Candidates for entry to the degree programmes of the Department must satisfy the University minimum entrance requirements. Such requirements are met by the possession of the West African School Certificate/the Senior Secondary School Certificate or the General Certificate of Education with passes at the credit level (or above) which must include Chemistry, Physics and Mathematics including English language.

On arrival on campus, your first pre-occupation would be to register as a student of the University. To do this, you will first of all need to report to the Secretary of the chemistry Department for the collection of clearance forms. Direction will then be given you on how to proceed further with the registration exercise. Fill our out all forms as neatly and as completely as possible. Originals of your certificates (academic qualification, statement of results, birth certificates etc) will be required at this stage. This is also the stage, where failure to meet the admission requirements can lead to the denial of your registration. Your registration exercise, in such a situation, would practically terminate at this point. A series of signatures would be required at this point, usually starting with registration officers at the Academic Office, followed by the finance division (Bursary Department). Early registration is recommended, because, as a freshman, you may, following registration, qualify for accommodation in one of the halls of residence. Part of the registration exercise requires the choice of courses (study programme) for the academic session. At this stage you will be assisted by Registration Officers at the Departmental level.

Your entire academic work load for the degree programme is structure into academic sessions. Each academic session (year) is sub-divided into two semesters. Each semester lasts for 15-17 weeks. By the course system, which the University operates, each course offered in any semester is examined by a written and or practical examination at the end of the semester. About two weeks are usually set aside for examinations at the end of lectures during each semester. You will also be required to write a series of continuous assessment tests in each course taken during a semester. Scores obtained in such tests would constitute a substantial part of your final grade in the course.

All students (Pure & Industrial) must spend a minimum of 3 years (direct entry) or 4 years for students admitted through UME and Remedial and must have passed the minimum required credit units, submit a research project and must have attended 6 months’ Industrial training in a Chemical Industry.

Four-Year Degree Programme in Pure Chemistry:

Students wishing to read for the Degree in Pure Chemistry shall register for all the required courses listed in the programme for their year of study.

 

Four-Year Degree Programme in Industrial Chemistry:

Student wishing to read for the Degree in Industrial Chemistry must register for all the required courses in the Degree Programme at the 100 – 400 levels. Enrolment for the Industrial Chemistry Programme started at the beginning of the 2004/2005 at 100 level.

 

We do incorporate continuous assessment into the examination system, this accounts for 30% of the overall score.  The continuous assessment comes from:

  1. Practical work.
  2. Class tests and assignments.  The overall scoring and grading system is as follows:

  1. Moderation Schemes:  100L – 300L questions are moderated internally by other lectures in the related fields, while the400level questions for degree examinations are moderated by external examiners appointed by the University.
  2. Issuance of Results: Programme semester results are approved by the Department Board of Examiners followed by the approval of the Faculty Board and finally by the University Senate before it is released to the students in the letter grade score by the academic office.
