USING SCREENCASTING TO ASSESS ANNOTATION
Kerry Pusey, University of Macau, Taipa, Macau SAR

Last semester, students in my upper-intermediate English for academic purposes (EAP) courses were required to annotate a text as part of a critical thinking module, which also included a summary and critical response to the text that they annotated. This three-part assignment constituted one of the major assessments for the course and was mandated across all sections of the level (about 10 in total). While I had taught and graded the genres of summary and response in the past, it dawned on me that annotation wasn’t something I had explicitly taught before—at least not to any great extent—and it definitely wasn’t something I had ever tried to formally assess. In fact, it seemed questionable to me whether one could assess such an idiosyncratic document (or process?) in any kind of objective way. However, as a newcomer to this particular language program, I decided I should just go with the flow and see how the assignment panned out.

So in spite of these initial qualms, the assignment was carried out as planned: Students chose and carefully annotated a text (one of five approximately 1,500-word academic essays) and then scanned and submitted their annotations via our course Moodle webpage. After a calibration meeting where the other teachers and I refined the criteria for assessment and identified benchmarks for different score ranges, the annotations were then assessed by individual teachers and scored using a rubric developed for the task.

The result? The annotations proved to be rather difficult to assess for the following reasons:

Lack of Consistency Among Texts

While three of the texts followed the prototypical structure of a problem-solution essay, the other two texts did not. This inconsistency among texts was problematic because, while the problem-solution papers lent themselves to a certain variety of annotation techniques (e.g., highlighting the thesis statement, labeling the text structure in the margins), the other two texts elicited annotations that were highly varied and (incidentally) seemed to miss the point of the texts. This resulted in a high degree of variation among students’ annotations, making it difficult to fairly score different students’ work.

Unclear Purpose for Annotating

Usually readers have a specific purpose for annotating. For example, they may want to find support for their arguments when writing an essay or identify information from a reading that they will be tested on later, or perhaps they just want to engage more deeply with the text in order to improve their reading comprehension. For this assignment, however, we were not as clear as we should have been about the purpose of the annotations, which led to a lack of common focus among students’ work (similar, in a way, to the effect of including texts with different rhetorical structures).

Ambiguity of Annotations

As is quite common in actual practice, students did not label every part of their annotations. This caused difficulties in terms of interpreting the meaning or purpose behind their annotations (i.e., the reasons why parts of the text had been underlined, highlighted, circled, etc.).

The Solution: Using Screencasting to Fill in the Gaps

Reflecting on the causes of the problems listed above, it seemed to me that the first two issues (inconsistency of texts and purpose for annotating) could be addressed fairly easily by predetermining the type of texts that students would use and giving students a clear purpose for annotating at the outset. However, the last issue (ambiguity of annotations) remained problematic because without knowing the unstated logic or reasoning behind students’ annotations, it would be difficult—if not impossible—to fully understand why they annotated in a particular way.

And then a thought occurred to me: What if we could access those cognitive processes? How could this be accomplished? Eventually, I came up with the following solution: Have students create screencasts in order to fill in the gaps of their annotations. In other words, ask students to include a narrative component to explain aspects of their annotations that would otherwise be ambiguous.

This idea was inspired in part by work that a colleague of mine had done using screencasts to give written feedback and is a sort of spin on the think-aloud protocol (or self-report). This elicitation technique is used in applied linguistics research to gain access to the cognitive processes that second language learners engage in when performing language tasks (Cohen, 2012) and is viewed as a vital means of assessing the validity of assessment instruments (Green, 1998, cited in Cohen, 2012). Thus, the use of screencasting seemed particularly apt for assessing annotation skills, as it simultaneously grants access to the visual component of the annotation while also addressing the issue of ambiguity through the inclusion of an accompanying narrative.

Assignment Details

During the following semester, I decided to test this technique with two of my classes (once again, upper-intermediate EAP classes). This time, however, the purpose was more specific and the task itself more authentic. Because students were in the process of gathering sources to write a problem-solution essay, I asked them to annotate one of the sources they were planning to use in their papers. I then had students create a screencast using the free web application Screencast-o-matic to explain their annotations and tell how their source would be incorporated into their papers.

Before giving out this assignment, we reviewed the purposes of annotating and various techniques that can be used. I also created a screencast of my own explanation of the assignment in detail, provided two sample annotation screencasts, and created a step-by-step guide for how to use Screencast-o-matic.

Below are the directions to the assignment that I gave students:

I would like to know more about the annotation techniques you use and how annotation helps you obtain important information from texts you read. For this assignment, please do the following:

  1. Carefully annotate one of the sources you plan to use for your problem-solution essay.
  2. Scan your annotation and obtain the color PDF file.
  3. Open your scanned annotation (the PDF file) on a computer.
  4. Open Screencast-o-matic.
  5. Record a 3- to 5-minute screencast to explain the following information:
    a. The source you’ve annotated and its relation to your essay topic (be brief)
    b. The annotation techniques you used (e.g., brackets, squiggly lines, stars)
    c. The aspects of your annotation that might be difficult for someone else to understand (i.e., things that are not clearly labeled, such as highlighted sections)
  6. Save your screencast as an MP4 and upload your file to Moodle under the “Annotation Screencast” assignment submission by (date), at midnight.


Assessment Procedures

To assess students’ annotation screencasts, I developed a rubric, which was modeled on the rubric used in the previous semester for the first annotation assignment. As I had hoped, the verbal report information was very useful in clarifying the ambiguities in students’ annotations. I also found that the rubric was fairly easy to use and resulted in a fairly normal spread of scores (in the statistical sense). I should mention that while the rubric does not explicitly state “explains relevance of the text to essay,” almost all students did so, as it was one of the main directions given for the assignment. I ended up considering this criterion as part of the “evidence of critical thinking” band, in addition to the other criteria listed.

Guidelines and Other Considerations

This assignment or adaptations thereof can be quite useful for assessing students’ ability to annotate effectively and think critically. However, there are a few things that should be considered before asking students to complete such an assignment.

First, you should consider whether the task will be a high-stakes or low-stakes assessment, as this may have implications for scoring procedures. Specifically, if you were to adopt this as a major form of assessment, it would be advisable to use two raters (to increase reliability) and to conduct norming sessions and establish benchmarks before scoring. For lower stakes assessment, such procedures might not be necessary (and may ultimately be impractical).

Another consideration is how you define the purpose of the task. As mentioned earlier, there are many specific purposes for annotating a text; depending on your course objectives, students’ proficiency level, and their English needs, the assignment should be adapted so that it’s most relevant to your course and meaningful to students.

Finally, it should be mentioned that the process of assessing the screencasts can be a bit time-consuming, so you should be prepared for this and think carefully about your resources (in terms of time) before giving the assignment. Nevertheless, I believe it is time well spent that can provide insight into a wealth of information about students’ reading and critical thinking skills.
