Context Diagram/Data Flow Diagram

Aswell as producing a spreadsheet that will function as a Markbook, we had to produce a Context and Data Flow Diagram. The Context Diagram was not that difficult to construct but the Data Flow Diagram was a litlle more difficult due to the further level of detail not seen in the context diagram. To solve this I drew the Data flow diagram first on a paper as it is more easier to maneuver the different processes, flow of data and the different symbols used.

My Gantt Chart

Gantt Chart-shows the overall timeline for the project. As seen above most of my time went into planning, i even began designing whilst i was still planning. The whole project took about 2.5-3 weeks to complete.

Turning Points

A great tutorial that i came across during this project, which was a big help in creating my markbook is shown in the linke below.

Difficulties

So far during this project, i had a difficult time trying to remember how to use a macro. I solved this by asking the teacher. Another problem that i faced was the slowness of the computer, which limits the time i have in class to complete the project.

Task 2: Individual Project

To begin the project, I have been researching different markbook systems and the different features they have to offer.
These include:
*Ability to grade students
*Scale scores
*Print graphs of student progress
*Easy calculation of complex student assessment tasks through simple selection of all common statistical functions.
*statistically accurate ways of combining, weighting and transforming student test and assignment marks quickly and easily
*scaling options such as respecifying the mean and standard deviation of a test, scaling to a new maximum mark, moderating a set of tests based on a common test, multilinear mapping and assigning of Alphabetical Grades (based on user defined cutoffs)
*include detailed manual
