Student projects/Blog improvements
Note: You are currently viewing documentation for Moodle 1.9. Up-to-date documentation for the latest stable version is available here: Student projects/Blog improvements.
This project aims to make improvements to the existing blog component and add a blog assignment module. Blogs can help immensely in keeping a student's work and an instructor's supervision coordinated, especially in self and group-directed projects or long-term assignments. The blog assignment module will make it easier for instructors to take advantage of the existing blog component.
The improvements to the blog will be a new system of relating course entities to blog posts. Assignments (and other modules), groups, and courses can all be associated with blog posts, providing a method of filtering a blog at each level and thus avoiding the need to search through a blog for relevant posts from a student enrolled in multiple classes. These relations also provide a means of access control for group projects and the notion of a group blog. A group may pertain to several students, and blog posts from each student related to the project can be filtered out of each of their blogs and combined on a single view. Specific blogging assignments can also be associated with blog posts so the instructor is aware of which posts the student wishes to have considered for evaluation.

- Provide a means for organizing blogs in terms of which courses and assignments the blog entries are relevant to
- Provide a means for viewing blog entries for students collaborating on group projects
- Provide a means for students to blog about certain modules within a course, or the course itself
- Provide a means for allowing students to set viewing restrictions for given associations and for teachers to require certain viewing restrictions

Progress can be tracked in-depth on my blog. Completed stages are marked out on the list above. The first item that is not marked out is the current item I am working on.
Associations will appear with icons under the tags portion of a posted blog entry. Each links to a list of blog entries associated with the course/project/assignment selected just as they are when a tag link is visited.
Settings for how many associations may be made for an assignment and the maximum visibility that may be used for an assignment will be present on the edit page of a blog assignment.
Stores associations between blog posts and other moodle entities. This table is similar to the "tag_instance" table. An accompanying 'association' table will not be necessary as the id's in this table point to other existing tables, and the association itself has no substance as tags do.
|contextid||int||The id of the context being associated with the blog post (from table 'context' field 'id')|
|blogid||int||id of the blog post being associated (from table 'post' field 'id')|
Several security issues exist for this project, such as:
- who may read blog entries with particular associations
- who may use particular associations with their blog entires
- who may grant permission to use certain associations
When creating a blog assignment, teachers can require the student use certain access restriction levels for the entries they associate with the assignment.
For students, the blog settings panel should include options for visibility of entries associated with any of the courses, groups, or assignments the student has access to. Two options will be included: the first will be the default visibility, and the second will be the visibility which takes precedence until the due date. These fields will be populated with only those values allowed by the instructor. Possible values are:
- Everyone on this site
- Members of the class
- Group Members (for group associated entries)
- Yourself (only the author and teachers)
These are what I see as the points where community members may want to see something different from what I've settled on. My answers to each question follow in bold.
- Is the "project" feature desired? If not, would associating blog entries with groups be desired? - The 'Project' feature will not be implemented, and instead associations with groups will be implemented
- How extensible should the associations be?
- At the database level, blog posts will be associated with moodle contexts. Support for assignments will be added first, followed by other course mods, and other contexts as time permits.
- Should teachers be able to set permissions for using associations on a per-student basis?
- No, because Moodle is role based
