Frequency of occurrence is the main way for teachers to choose what to teach when using corpora however as Andrew Walkley discusses in “Word choice, frequency and definitions” using just frequency is not without limitations. In addition to frequency we can use semantic transparency/opacity, that is, how the meaning of the whole differs from its individual parts. This is also sometimes referred to as how idiomatic a phrase is. Martinez (2012) offers a Frequency Transparency Framework that teachers can use to help them choose what phrases to teach. Using four collocates of take he presents the following graphic:
The numbered quadrants are the suggested priority of the verb+noun pairs i.e. the most frequent and most opaque phrase would be taught first (1), then the most frequent and transparent phrase (2), followed by the less frequent but opaque phrase (3) and last the least frequent and most transparent phrase (4). As said this is only a suggested priority which can be changed according to the teaching context. For example a further two factors (in addition to word for word decoding) can be considered when evaluating transparency:
- Is the expression potentially deceptively transparent? – “every so often” can be misread as often; “for some time” can be misunderstood as short amount of time (Martinez & Schmitt, 2012, p.309)
- Could the learner’s L1 negatively influence accurate perception?
Applying the framework to the binomials list from my webmonkey corpus – I would place up and running in quadrant 1, latest and greatest in quadrant 2, tried and true in quadrant 3 and layout and design in quadrant 4. Note that I did not place drag and drop, the most frequent and somewhat opaque phrase since it is so well-known with my multimedia students (similar to cut and paste) that it would not need teaching.
