The most common strategies are surveys, interviews and focus groups. We will describe these first. However, there is a large number of evaluation strategies and the e3L team wants to encourage Hong Kong teachers to try out some of these other strategies. The strategies described on this site are:
Common strategies:
Other strategies:
Surveys
using questionnaires <top>
Interviews
<top>
A guided or structured interview is essentially a conversation between the interviewer and the interviewee. It is important to identify the key areas that are to be evaluated and then generate five or six key questions. The more open the questions, the more the individual experience is able to be captured. It may be that supplementary or clarification questions are asked during the interview; it is best to be flexible.
- Allow up to an hour for each interview.
- Either audiotape the interview with the permission of the participant or prepare detailed notes ASAP afterwards.
- The transcription or summary should be sent to the interviewee for approval before being finalized.
- Identify themes and code responses to match the themes. Locate quotations.
Variation:
- Use in conjunction with other more quantitative methods (e.g. questionnaire, checklist).
|
Focus
groups
<top>
These are moderated meetings of a sample of a class. They are useful for both formative and summative evaluation. They help to identify or clarify the key issues. Some points:
- A group size of 6-12 is good.
- Focus on key issues.
- It is usually better to take notes as the recording of several people is complex.
Variation:
Use to follow-up a quantitative method (e.g. questionnaire, checklist) to gain further clarification.

Web
logs
<top> |
Information about which parts of your website students visit, and when, can be very helpful.
- If you use WebCT or Blackboard, some statistics are built into the system. This may include the time of day that students work online.
- If you are using open websites, then counters can be put on each page.
|
Checklists
<top>
Confidence
Logs <top>
These are used to judge how confident students are with a specific activity. They are applied in order to:
- get a snapshot of student confidence in using the material, or
- compare the change in confidence of students before and after using the material.
Hints:
Identify the purpose of the log.
- Identify the purpose of the log.
- Give clear instructions.
- Compile a list of concise statements to put to students.
- Use language accessible to the students.

Discussion
archive <top>
In this strategy, there is an analysis of the interchanges between students in real time (synchronous) and asynchronous discussions, examining the nature of the interaction process and the quality of what is said. This can be time-consuming, but very informative. |
Ethnography
<top>
This is in-situ observation of a process or innovation. The aim is to observe the process or innovation within its intended environment with minimal effect on the environment. The ethnographic study acknowledges the environment in which it is happening. The data being collected are interpreted in context. This relies on describing the 'feel' as well as the ‘facts’. The evaluator becomes an observer. Anonymity in reporting is an issue. |
Expert
Review <top>
The outcome of an expert review is a report provided by an appropriate expert or group of experts. The type of expert depends on the aspect being investigated. It might be a subject matter expert, an instructional design expert, a graphical interface expert, or a combination of these.
The expert should have input to the criteria for the evaluation. With websites, expert reviews can be conducted online.

Reflective
journals <top>
The purpose of this strategy is to obtain students' interpretations of the process of understanding and learning. Students are asked to explain in writing how the technology may have assisted them to develop their understanding and learning of key ideas, with emphasis upon the understanding and learning processes. This requires careful structuring and exemplification if the journal is to move beyond a fairly low-level description of events and experiences. A useful framework is that of the five 'R' levels (Bain et al., 1999):
- Level 1 (reporting)
- Level 2 (responding)
- Level 3 (relating)
- Level 4 (reasoning)
- Level 5 (reconstructing)
|
Teach-back
<top>
| This can enable one to get insights into how a student's understanding is linked to the online experience. Students are asked to use the course website to 'teach' the interviewer about the material, and in doing so to show how the website assisted their understanding. It is more useful in open-ended 'constructive' interactive websites than in highly structured practice environments, but can be used in the latter. |
Testing
and User Trialing <top>
The purpose of testing is to verify that the product matches the requirements as outlined in the specification document. Testing should occur during the development stage to ensure the project is functioning successfully. It is a cyclical process and its time span depends on the size and scope of the project. The product needs to be specified clearly at the outset of the project so that comparisons may be made to see if the development is on track. As prototypes are developed, they undergo testing in terms of functionality, robustness of any programming code, compatibility across platforms, content, interactivity, look and feel. Problems are best addressed here.
The 'alpha' version is a near-complete build of the product which is advanced enough to undergo user trials. These are to provide usability information so that the design of the product can be modified as required.
The 'beta' version is developed for trialing after the modification pinpointed by the alpha version testing has been completed. It is a controlled introduction of an innovation or change that seeks explicit feedback from the users with a view to ensuring the innovation does what it is designed to do from the point of view of the user. |
Video
of think aloud <top>
| This type of video is used to record how students are thinking as they use a website. Students are asked to verbalise what they are thinking about as they work through materials on the website. It is useful when online thinking is not too demanding, but verbalizing can 'drop out' under heavy cognitive loads. It is important that this strategy only be used with students speaking in their first language. |
Video-stimulated
recall <top>
| This type of video is used to reveal how students are thinking as they use a website. Students are shown a video of themselves using the website and asked to say what they were thinking and why (best used with the split-screen technique so that the screen and student actions are both visible). This technique is less prone to the 'drop out' problem, but reliant on the video to cue memories rather than genuine real-time expressions. |
