Techniques and methods of isolation, enumeration, and means of studying transformations will be emphasized. Relevant research articles will be discussed during regular lecture hours. Overview of importance Why study soil microorganisms? Historical accounts and the Golden Age of soil microbiology.

If you miss class due to a valid, documented extenuating circumstance, it will not count as an absence. Examples of valid absences include: (a) family member serious illness or death; (b) official academic/athletic event (e.g. field trip); or (c) recommendation from an MD. Conversely, points will be lost for unexcused absences, being late to the class, leaving the class at will, class disruptions, etc. Late assignments will not be accepted except when due to the above-cited circumstances. Examinations will have subjective and objective sections. The Final will be a cumulative. Please be aware that definitions will be expected in the examinations. Quizzes will test specific points covered during recent lectures. Make-up quizzes will not be given - rather if you miss a quiz during an excused absence I will use an average of all your other quizzes to calculate a replacement score. Participation points will be awarded for attentiveness and positive contribution to class discussions. Conversely, points will be lost for unexcused absences, class disruptions, etc. Missing more than 4 classes will result in 10% loss of your final grade. Method of instruction is traditional lectures mixed with student discussion on relevant journal articles. Part of the class work may involve visit to garden/field and other labs/institutions of interest. Grade Evaluation Scale: 93-100 = A 89-92 = A- 86-88 = B+ 83-85 = B 79-82 = B- 76-78 = C+ 70-75 = C 59-69 = D <58 = F Please ask questions in class as this will greatly add to the discussion and learning process and let me know at anytime throughout the term how I can be of help. Note: This syllabus and course schedule may be updated, if needed. An announcement of changes will be made in class and in Blackboard Learning class webpage. 5
