  5. Learning Objectives • At the end of this course learners will be able to, • 1. State the water quality requirements for different uses. • 2. State the standards for potable water. • 3. Discuss the principle of water quality systems analysis • 4. Enumerate the water quality management tools and models. • 5. Explain benefits and socio-economic concepts of water quality management . • Explain the major reactions that govern the chemistry of natural waters

  6. 5. Taking the Course • There will be 15 lecture units arranged into 5 modules. The course will be taught using the asynchronous method. On weekly basis for 15 weeks. • A lecture unit will be uploaded on the course blog for the learners to access. Support CDs will be made available to on registration • Pretest will be administered preceding each lecture to assess basic knowledge in the subject matter. Performance of learners in pretests will not count in the final examination grades • Practice tests will be administered at the end of each lecture unit for learner’s self assessment and revision. • 5 tutor-marked assignments (multiple choice) will be provided for each module • At a particular period in each week, learners will be expected to participate in a chat or a discussion forum • The schedule for a chat/discussion forum will be communicated to learners. • List of frequently asked questions (FAQ) and answers will be made available to learners. • List of suggested readings will be made available to learners • Additional instructions to facilitate learning may be provided by teachers as deem necessary Learners must participate in 75% of the chat/forum to qualify for the final exam Taking the practice test improves your chances of success in the course Tutor-marked assignment accounts for __20__% of the final grade for the course, so submit promptly!

  7. 6. How to prepare for the final examination for this course - • This study guide provides an in-depth knowledge needed by learners to successfully take the final examination. Learners are encouraged to read and understand the entire content to ensure good performance in this course. • Learners should make use of the supplemental CDs provided as this will expand the knowledge of the learner. • Learners should note that the sample questions and practice tests provided at the end of each lecture will help learners to assess self and promote revision before taking the final examination. • Suggested readings will enhance learner’s performance in the final examination.

  8. 7. Prerequisites for Examination • For any learner to be eligible to sit for the final examination in this course, he/she must fulfill the following requirements • Participate in at least 75% of all online interactions

  9. 8. Preparatory Questions – Dr Afolabi • Which of the following reactions govern the chemistry of natural waters? • (a) Addition reaction • (b) Displacement and Substitution reactions • (c) Redox reaction and Acid base reactions • (d) Equilibrium reaction • The parameters for water quality assessment includes the following except • (a) PH • (b) Alkalinity • (c) Nitrate content • (d) Particle size . • Natural water cannot be in the pure form because water is • (a) available to all • (b) a good solvent • (c) universal solvent • (d) life • After each question, the answer should immediately follow along with an explanation on why that answer is the correct answer. • Example Question: • If a term is defined within the text of a section it does not need to appear in the glossary. True / False • Correct Answer: False. A term needs to be in the glossary even if it has already been defined in order to provide the reader with a quick reference.

  10. 9. Assessment • Assessment in this course will be done considering active participation of learners in all interactive sessions, quality of written assignments, records of materials used as references in all assignments, regular feedback from teachers and learners and performance in examinations. Details of assessment strategies are as follow: • Part A • Continuous Assessment: a. Participation in group discussions/chat room: (20%) with contributions showing thoughtful preparation for the classes. • Assignment: individual term papers, group reports: (20%). • Tutored marked assignment (20%) • End of course examination: a. This comprises 100 multiple choice questions covering all topics covered in the course (40%)

  11. 9b. Feedback and advice: • Feedback will be from teachers to learners (you) and learners (you) to teachers. • The Course has a feedback blackboard available on __ronkeokoya.wordpress.com_______ (show the hyperlink). • All assignments have information about deadlines for submission after which submissions by students will be automatically rejected. • Results of all assignments (scores) will be released within 72 hours of the deadlines. • Summary of records of learners’ participation in all online sessions will be presented on the feedback blackboard for the course • Learners can also share information with peers on the feedback blackboard • Students are required to submit their proposed topics for term papers on the course • Students can contact their lecturers through their e-mail address for information, clarifications and support

  12. Exam arrangements • All examinations are conducted online. The site for end of course examination may be decided by the institution but candidates will be given information about this ahead of time • Continuous assessment • a. Assignments: individual term papers, group reports: List of assignments for each topic is available on the content area of the course • End of topic short tests comes within seven days of completing the topic. End of course test takes one hour and students will be informed of when to log on to do the test. Questions are withdrawn at the end of one hour after the questions would have been presented online. • The results are released automatically • End of course examination: • This comprises 100 multiple choice questions covering all topics covered in the course (40%) • Time allotted for this examination is 1 hour 0 minutes and it follows the same format as done with the end of topic tests.

  13.
