Identifying a bottleneck to learning is the first step in the seven steps of Decoding the Disciplines. This step involves identifying a particular place in a course (or in a series of courses) where significant numbers of students are unable to adequate perform essential tasks. Such places are refered to as bottlenecks.
Describing bottlenecks
It is generally better to be explicit about the nature of the problem and to focus on the task that students are unable to carry out. Here are examples of productive and unproductive ways to complete this step:
Example: English
Vague: Students cannot interpret texts.
More Useful: Students in literature classes have a particular problem in the basic approach to textual interpretation. Students forever want to go directly to interpreting a text without first getting a good grasp of a text’s content. They need to observe before they interpret, but they are constantly skipping a thoughtful observation stage. Skipping this stage leads to poor interpretations.[1]
This observation is specific enough and provides enough information that it can serve as a starting place for the analysis of the bottleneck.
Example: Biology
Vague: Students have difficulty moving from fact learning to a deeper understanding of biological processes.
More Useful: Students have difficulty visualizing chromosomes, appreciating the distinction between similar and identical chromosomes (i.e., homologs and sister chromatids), and predicting their segregation patterns during mitosis and meiosis.[2]
It is important to focus on specific tasks that many students find difficult and to avoid beginning with moral judgments (students just don’t care) or general cultural theories (electronic media are corrupting the learning process). It is generally more productive to concentrate on the specific places where students get stuck and to try to understand the nature of the problem.
Cognitive and emotional bottlenecks
The obstacles to learning come in two varieties, cognitive and emotional bottlenecks. Somewhat different strategies are needed to deal with each. In some cases there may be both cognitive and emotional bottlenecks to learning.
Cognitive bottlenecks
In these situations students’ learning is blocked because they have failed to master particular mental operations. To help them overcome these obstacles, it is necessary to first make explicit for oneself precisely what steps are necessary to complete the work that students find so difficult. (Step 2 of the Decoding process)
Emotional bottlenecks
In other cases students’ difficulties revolve less around cognitive difficulties, than around the negative emotional reactions of students to either the processes of the course (e.g. students are upset that the work in this course does not match what they did in high school courses in the discipline) or to its subject matter (e.g. some of the findings in the discipline are at odds with things students were taught as they were growing up). This second set of emotional bottlenecks will be dealt with in step 5 of the Decoding process.
