OUTLINE OF CLASS ACTIVITIES

This page provides an outline of the class activities. Together with the Objectives, it should be read beginning-to-end before the Jan. 7 Wednesday lecture period so that you have a sense of how the class will operate. You should also have a first look at the Assessment Scheme, which is an "Individually Weighted Scheme"; we will discuss it in class. More details on specific activities are or will be posted on the WebCT site which you can consult when we begin those activities.

THE TWO PHASES

The class has two phases
  1. The Learning Phase, covering the first 8 weeks
  2. The Application Phase, covering the final 4 weeks.
The Learning Phase will be spent studying and discussing basic factual material and concepts, doing numerical problem-solving exercises, and searching for and evaluating relevant data bases on agroecosystems. Through this period, students will work in groups, and learn to communicate and build a common data base using Web based tools.

In the Application Phase, the accumulated materials, new expertise, and team work skills will be applied to the task of building an Agroecosystems site on the Web.

LEARNING PHASE: DAY BY DAY

We meet three times a week (MWF). The First Week.

In the first week (Jan. 5, 7, 9) we will discuss the class, form Working Groups, and learn to prepare a page with HTML tags using an HTML editor.

One of the tools we are using is WebCT (CT stands for Course Tools). This program makes on-line use of a Web Browser (Netscape) to post notices, accumulate class material, and facilitate on-line chats and other activities within the class. These activities and files are accessible only to class members. In the Learning Phase, we will build up a bank of materials on our WebCT site which we can draw on in the Application Phase. All reports in the class will be submitted as Web-ready pages.

The rainy season was unusually late, resulting in transplants that were spindly and chlorotic. Extensive deforestation of the uplands may be contributing to more erratic rainfll patterns.

During weeks 2 to 8, Mondays, Wednesdays and Fridays will follow a routine

Mondays are PS Days (Problem-Solving Days) on which the routine will be:

  1. dp presents a quantitative problem.
  2. Students congregate in their Working Groups.
  3. One group agrees to be the Reporting Group for the week.
  4. Each group discusses the problem and proposes an approach (model) to solve it.
  5. The class as a whole discusses the problem.
  6. If we find that we need more information to solve the problem or clarify a concept, a student volunteers to find the "Information Needed", and prepares a MIC (Monday Information Card) for one 'Research Credit'.
Members of the Reporting Group take notes on the proceedings, organizing the information for a Monday Report under five headings: (i) Definitions, (ii) Concepts, (iii) Formulas and Units, (iv) Information Needed, and (v) Overview. Individual members prepare different sections of the Report which they send by e-mail to a member who has agreed to be the Compiler for the week. On Friday, the Reporting Group meets in B400 to review submissions, complete the report, and submit it to our WebCT site. The Report is reviewed by class members over the next 10 days, critique is offered in class, discussed and the Report revised as necessary. Students will be responsible for this material.There will be a problem-solving/definitions test on April 8.

Wednesday are Text Days.

Over the first 9 weeks, we will cover chs. 1-8 of the text, roughly at the rate of one ch. per week. Chapters 1,2, 6,7,8 will be assigned for self study, followed by tests and class discussions of the material. "Guiding Questions" will be provided for each of these chapters to indicate which parts are most pertinent to our class (and to tests). dp will give lectures related to chs. 3,4, and 5 and assign portions of them for self study. We will also make use of the text in our Monday PS sessions as a source of information.

The schedule for the chapters is as follows

  • Jan 7: assign chs 1&2
  • Jan 14: test on chs 1,2
  • Jan 21: lecture on ch 3; assign ch. 6
  • Jan 28: test on chs 3,6
  • Feb 4: lecture on ch 4; assign ch 7
  • (Feb 11: Guest lecture)
  • Feb 18: test on chs 4,7
  • (Feb 25: Feb break)
  • Mar 4: lecture on ch 5, assign ch 8
  • Mar 11: test on chs 5, 8
On each of the 4 test days, the routine will be as follows:
  1. At the beginning of the class, a test is given and completed individually (15-20 T/F, MC, SA questions).
  2. Students congregate in their Working Groups, discuss the same test as a group, and answer the test as a group.
  3. The group tests are marked in class.
  4. The rest of the lecture is spent discussing the text material, and the application of the ecosystem concept to agricultural systems.
  5. WICs (Wednesday Information Cards) may be assigned.

Fridays are Web Days

     
  • We meet 12:30-14:30 in Room B400 in the Killam, where there are 20 computers.
  • The Reporting Group discusses each member's contribution to the Monday Report, an Overview is written and the report prepared with HTML tags. It is then placed on the WebCT site and reviewed by the class over the next 10 days
  • Students who prepared MICS or WICS likewise submit them to the WebCT site.
  • This time is available otherwise for students to work on computers in relation to their Special Topics assignments, or to do some "Agroecosystem Web Grazing"
Contents 

OTHER LEARNING PHASE ACTIVITIES & TOOLS

  • Special Topics: Students will choose one or two special topics assignments. These are researched as they would be for a term paper, but the report is made as a Web page.
  • Demonstration Lab: Room 6078, next to dp's office will be set up as a demonstration lab which students can access at other times of the week (times to be decided after discussion in class). It will contain demonstration materials, and a computer on which a dynamic modeling tool (Stella) can be run.
  • Bulletin Boards: There are two Bulletin Boards: an Ecosystems Board where we will carry on a discussion about the Ecosystem concept and how it can be applied to agricultural systems, and a Banter Board, which will carry everything else.
  • Glossary and References. There are glossary and reference functions on the WebCT site, which we will be using once we have worked out a class protocol for doing so.
  • On-Line Chat: This function is available at the WebCT site; you may want to try it out early on within your group so you have a sense of how it works, and how you could use it. One possible use: a Working Group or an individual might use On-Line Chat to interview someone in a distant location in relation an Agroecosystems topic.

THE APPLICATION PHASE

After the final Text Day ( March 11), we will shift gears and apply all of the skills and materials we have accumulated to a task, which is to build an Agroecosystems Web site.

This exercise is one that will benefit from both discipline and creativity - the discipline to ensure that what we finally put on the Web is credible, as free of errors as possible etc., and creativity to make it an interesting and useful site. The peer review process that you will have developed in Working groups in relation to the Monday reports and Special Topics will be applied to the building of the Web page.

We will formulate as a class the precise objectives of this exercise, and how we will go about doing it. Here are some of my initial reasons for including this exercise :

  • there is not to my knowledge, an equivalent site on the Web, and I do have a sense that there would be considerable interest in it, also in the process by which we do it - it is a worthwhile exercise and one which we will all author
  • it provides a focus for the factual learning we do in class, as well as for individual Special Topics work, and Group work
  • it challenges us to be creative, which makes the drone part of the learning process easier
  • it challenges us to be disciplined in an editorial context.
