Bachelor of Science in Environmental and Biosystems Engineering

Overview

Background

Biosystems Engineering (BE) is a field of engineering which integrates engineering science, design and fabrication/construction with applied environmental, agricultural, and other biological production systems. It represents an evolution of the agricultural engineering (application of the science and art of engineering to production, storage, and processing in agriculture) discipline applied to all living organisms. Therefore, Biosystems Engineering is the branch of engineering that applies engineering sciences to solve problems involving agriculture, environmental, and other biological production systems. According to the UNESCO Standards Classification of Education and Training (ISCED -F, 2013), Biosystems Engineering is broadly classified under code 07 (Engineering, Manufacturing, and Construction).

Philosophy of the Programme

The philosophy of the programme is to enhance industrialization and production efficiency, water and food security, and poverty reduction to achieve sustainable livelihoods and environmental well-being at the household and community levels.

Rationale of the Programme

The motivation to review the programme was prompted by first, the need to align the curriculum to the Statutory and Regulatory requirements to keep abreast with the rapid changes in the industry. Second, to incorporate the recommendations from the consultative forum of key industry stakeholders and universities that was held at ICIPE Center (Duduville) Kasarani, Nairobi in 1997; and later meetings held with the former Engineer Registration Board (ERB) now Engineers’ Board of Kenya (EBK) to align the programme with the EBK requirements.

Goal of the Programme

The goal of this programme is to produce graduate biosystems engineers with requisite skills and competencies (design, innovation, and programming) acquired through the theory and practice of the engineering profession.

Expected Learning Outcomes

At the end of this programme, the learners should be able to:

  1. Apply the theory and practice of mathematics, and basic and engineering sciences to solve Biosystems Engineering problems.
  2. Conceptualize and conduct research in Biosystems engineering problems and communicate solutions.
  3. Design and synthesize efficient systems, components, engineering works, products or processes to meet desired needs within realistic constraints such as economic, environmental, social, political, ethical, health and safety, manufacturability, and sustainability.
  4. Work effectively with professional colleagues and the community, act ethically, and take responsibility for action taken within the limits of competence
  5. Demonstrate entrepreneurship, management, and decision-making skills.

The lecturer is obliged to:

      1. Attend and deliver all scheduled lectures in a course. If he/she is unable to attend any lecture sessions, arrange with the learners for appropriate makeup.
      2. Avail to the learners the necessary tutorial problems and other assignments.
      3. Assess (mark) and discuss with the learners all assignments, labs, computer programmes and continuous assessment tests on time.
      4. Keep abreast of new developments in his/her field and update the teaching materials accordingly.
      5. Set and mark all examinations on time
      6. Be available for consultation outside class hours
      7. Counsel and mentor the learners.

STUDENT ASSESSMENT CRITERIA

Formative Assessments

The learners shall be assessed (as appropriate for each course) through assignments, quizzes, laboratory reports, workshop exercises, computing exercises, reports of industrial visits and attachments, continuous assessment tests, term papers, oral presentations, projects reports and other related deliverables.

The marked scripts shall be returned to the learners in good time and discussed so the learners can take corrective action where necessary.

Summative Assessments

Except where stated otherwise, each course shall be examined by an end of semester examination. The final grade in each course shall take into consideration both the formative assessment results as well as the examination result.

The grading system will be as follows:

Score

Grade

70% and above

A

60 – 69%

B

50 – 59%

C

40 – 49%

D

0 – 39%

E

 

Attainment of Grade E means a student has failed the course and the student does not get academic credit for the subject. A student who obtains an E grade is allowed to remedy the situation by sitting for a supplementary examination at the end of the academic year or repeating and passing the course in the following academic year depending on the number of courses failed.

A supplementary examination will only be available to a student who has failed a maximum of four courses in the academic year. A pass in a supplementary examination will result in an overall E* grade in the subject.

Written Examinations

The current approved examinations regulations of the school of engineering and any subsequent changes by the Senate shall apply. The current regulations are as follows;

      1. Courses shall be evaluated in terms of course units. A course unit with laboratory/workshop exercises shall be defined as made up of four (4) contact hours consisting of lecture/ tutorial/ practical per week for 15 weeks, totaling 60 hours. A course unit without laboratory/workshop exercises shall be defined as made up of three (3) hours of lecture/tutorial per week for 15 weeks, totaling 45 hours.
      2. Courses that are spread over two semesters shall be examined at the end of the second semester.
      3. All courses taken in a given semester shall be examined by written ordinary examinations at the end of that semester unless otherwise specified.
      4. A written Ordinary Examination for a course unit, where it applies, shall have a minimum duration of two hours. A course with more than or less than 45 contact hours shall generally be examined for a duration proportional to the 2 hours for the one-course unit, such as:

            45 contact hours          -           2.0 - hours examination

60 contact hours          -           2.5 - hours examination

90 contact hours          -           3.0 - hours examination

The pass mark in each course shall be 40 per cent of the maximum mark possible in the course.

      1. Each course unit shall be graded independently out of a maximum of 100 marks (for 45 and 60 contact hour courses).
      2. The complete assessment of a course unit shall consist of continuous assessment tests, course/laboratory/field assignments and end of semester written examinations, with the three components ordinarily carrying 10, 20 and 70 marks out of 100 respectively.
      3. Where a course unit does not have any laboratory/field assignments, or coursework, the continuous assessment test and end of semester written examinations shall carry 30 and 70 marks out of 100 respectively.
      4. Where a course unit is examined entirely by coursework, or laboratory/ field assignments, such course unit shall carry all 100 marks.
      5. Where distribution of the marks for a course does not conform to (a), (c) or (d) above, the distribution of the marks for the course unit as approved by the Senate shall be followed.
      6. Where a course consists of more than or less than a one-course unit, the assessment in (a), (b), (c) and (d) above will be graded on a probate basis concerning the one-course unit.
      7. The final year project shall be considered as two course units.

To be allowed to proceed to the next year of study a candidate shall have obtained an aggregate mark of not less than 40 per cent and passed all examination units.

    1. A candidate who fails up to four units in a year of study shall be allowed to sit for supplementary examinations within three months.
    2. A candidate who fails the project in the final year of study shall be allowed to resubmit the revised project within three months. A candidate who fails the resubmitted project shall be allowed to repeat the year of study.

A candidate who:

    1. Obtains an aggregate mark of not less than 40 per cent and has failed in more than an equivalent of four-course units but in not more than an equivalent of 8, or
    2. Obtains an aggregate mark between 30 per cent and 39 per cent inclusive and has failed in not more than an equivalent of 8-course units,

Shall on the recommendation of the School Board of Examiners and approval by the Senate, be required to repeat the year of study and attend classes in the failed units and take the examination in the failed course units at the next Ordinary University Examinations.

A candidate who:

    1. Obtains an aggregate mark of less than 30 per cent or
    2. Has failed in more than an equivalent of eight (8) course units, or
    3. Has failed the same course unit four times or
    4. Has failed to take prescribed examinations without good cause,

Shall on the recommendation of the School Board of Examiners and approval by the Senate, be discontinued from the course of study.

A candidate who fails to satisfy the examiners in the supplementary examinations shall, on the recommendation of the Board of examiners and approval by the Senate, be allowed to repeat the year and sit the examinations in the failed course units at the next Ordinary University Examinations, subject to the provision of the regulation (a) (c) above.

    1. A candidate who fails to take prescribed examinations with good cause may be allowed by Senate on the recommendation of the School Board of Examiners to take Special Examinations at the next Ordinary University Examinations/ Supplementary Examinations.
    2. Examinations taken under this clause shall be treated following clause (7.1.5) and shall be graded in full.
    3. A pass obtained in the supplementary examination for a course following clause (7.1.6) shall be adopted as 40 per cent and will be entered as 40 per cent which will then be the mark entered in the candidate’s academic record.
    4. The mark adopted according to this clause shall be used to calculate a new aggregate mark for the candidate.

 Project Assessment

Assessment for the whole course unit (FEB 540) is 100 per cent by coursework and oral presentations. The distribution of the marks shall be based assessment formats provided by the Department as shown below along the following anticipated deliverables:

  • Concept Notes   5%
  • Concept Paper   5%
  • Full Project Proposal 10%
  • Oral Seminar Presentation 20%
  • Oral Examination Seminar 20%
  • Final Design Project Report 20%
  • Logbook Assessment 10%

 

The Final Design Project Report shall be assessed by the project supervisor and at least two Independent Internal Examiners knowledgeable in the field in which the project falls. And the Final Score shall be taken as the Mean of the marks awarded by the three (3) examiners. In case the individual marks awarded by the three Examiners differ by more than 20 %, then the External Examiner will moderate.

Before any examination paper is taken, it shall be moderated by an internal moderator nominated by the Departmental Board of Examiners from amongst the senior academic staff. The moderated paper shall be sent for external moderation by the external examiner. Likewise, the marked scripts shall be moderated by the same set of internal moderators and external examiner. Further moderation of the marks shall be undertaken by the Departmental Board of Examiners, the School Board of examiners (School of Engineering) and the College Academic Board (College of Architecture and Engineering) before sending it to the University Senate for approval.

 Moderation of Examinations

There will be two levels of moderation of examinations

  1. Internal moderation: upon Lecturers setting the examinations, the Chairman of Department will identify suitable Lecturers within the department to internally moderate all the examinations before they are sent for external moderation.
  2. External moderation: The examinations will be sent to an external examiner appointed according to the rules of the university. The external examiner will review the examination papers before they are sat. Once the examinations have been marked, the External examiner will review the performance in the examinations and provide a report.
