Evaluation of this WebQuest, of course, will vary according to the level and ability of the students that you are teaching. Remember to provide students with a clear set of expectations or a rubric that tells them exactly what you will be looking for. Aspects to consider for evaluation include:
- Task completion: Did students finish all related details?
- Credit: Was source and reference information included? Did the student cite sources in an acceptable manner?
- Comprehension: Does the student's finished project show understanding of the concepts you wished him or her to comprehend?
- Cooperative Learning: Did students collaborate with one another in a productive fashion?
- Presentation: Was the project shared in a clear and creative manner? Did the student's work conform to grade level standards for grammar, spelling, neatness, and/or public speaking?
