Wiki vs Blog
Wiki vs Blog
- Both are Web 2.0 tools
- Wiki: collective voice, shared editing, non-chronological pages, knowledge building
- Blog: individual voice, single author, reverse-chronological posts, reflection
- Wiki best for group projects, glossaries, shared notes
- Blog best for portfolios, journals, opinion pieces
- Wiki produces one shared document; blog produces a series of posts
Wikis and blogs both come from the same wave of Web 2.0 tools that let ordinary users publish content online. They look similar at first glance, but they shape classroom work in very different ways. Choosing the wrong one wastes time. Choosing the right one makes the activity match the learning goal.
The core difference
A wiki is a shared document many people edit. Voice is collective and objective, like an encyclopedia article.
A blog is a personal channel where one author publishes posts. Voice is individual and reflective, like a journal.
That single difference shapes everything else: the workflow, the ownership, the assessment, and the type of learning each tool supports.
Comparison table
| Feature | Wiki | Blog |
|---|---|---|
| Main purpose | Collaborative knowledge building | Reflection, expression, updates |
| Voice and tone | Objective, neutral, encyclopedic | Subjective, personal, conversational |
| Structure | Pages linked by topic, non-chronological | Posts in reverse-chronological order |
| Authorship | Many authors edit the same page | One author per post; readers comment |
| Workflow | Constant revision of one shared document | New posts published; old ones rarely edited |
| Best for | Group research, class glossary, shared study guide | Portfolios, reflective journals, opinion pieces |
| Teacher role | Facilitator and monitor of contributions | Prompt setter, comment moderator, feedback giver |
| Assessment focus | Team contribution, accuracy, synthesis | Reflection, argument, individual voice |
| Sample task | Class wiki on pioneers of computing | Weekly blog reflection on the teaching practicum |
When to use a wiki
Pick a wiki when the task needs many heads working on one piece of work. Examples:
- A class glossary for an ICT course.
- A group research paper on climate change.
- A shared study guide for a final exam.
- A class project documenting a community survey.
- A long-running class policy document students update over the term.
A wiki rewards negotiation. Students must agree on facts, structure, and tone. The final product belongs to the whole class.
When to use a blog
Pick a blog when the task needs an individual voice or a series of separate posts. Examples:
- A student e-portfolio with reflections after each lesson.
- A weekly journal during a teaching practicum.
- A class news channel where the teacher posts updates and students leave comments.
- An opinion column where students defend a thesis with evidence.
- A learning diary that tracks growth across a term.
A blog rewards personal articulation. The post belongs to the writer. Other students respond through comments.
How workflow shapes assessment
The two workflows lead to two ways of judging student work.
Wiki assessment
The teacher uses the version history to see who added content, who corrected errors, and who reorganised the structure. Grades look at:
- Quality of content added.
- Number and quality of edits.
- Cooperation in discussion threads.
- Accuracy of sources cited.
This catches the student who only joins in the last hour and rewards steady contributors.
Blog assessment
The teacher reads each student’s posts as a personal record of thinking. Grades look at:
- Depth of reflection.
- Strength of argument or example.
- Regular posting across the term.
- Quality of comments left on peers’ posts.
This rewards thoughtful, consistent writers and gives shy students a way to show their best thinking.
Objective and neutral, like an encyclopedia.
A wiki is a shared document, so the writing should not sound like one person’s opinion. Personal voice belongs in a blog.
A worked example: same topic, two tools
Topic: water pollution in a local river.
As a wiki project: the class builds one wiki on the river. Group A writes the page on causes. Group B writes the page on health effects. Group C writes the page on government policy. Group D writes the page on solutions. Every page links to every other page. The final product is a small encyclopedia the class can hand to the local council.
As a blog project: every student keeps a blog with weekly posts. Week one is about a field visit. Week two is about an interview with a resident. Week three is a reflection on what surprised the writer. Week four is the student’s opinion on the most useful solution. Other students read and comment.
Same topic. Same effort. Two very different learning outcomes.
Educational value of both
Both tools support ICT integration, communication, writing, and student engagement. The key is to match the tool to the learning goal:
- A wiki produces a single shared document. Use it when the class is building knowledge together.
- A blog produces a series of personal posts. Use it when each student needs space to reflect, argue, or document personal growth.
A complete ICT-rich classroom may use both at different points in the term, taking care not to confuse the two.
