Any quantification means a loss of data (even reporting scores on a multiple-choice test means that what each student answered for each question is lost). However, quantification means that more data can be covered (allowing greater generalisability). In other words, a decision needs to be made between breadth (quantitative) and depth (qualitative).

For the following research focuses, is quantification of the data justifiable and why?

1. A researcher identifies different types of scaffolds and wants to see what scaffolds a teacher uses and the contexts in which they are used.

2. A researcher would like to investigate how certain scaffolds change the ways in which a group of students understand a language point.

3. A researcher wants to examine the bases for decision making as students navigate their way through a CALL program by asking the students to think aloud.

4. A researcher wants to examine how bloggers use language to establish a relationship with their audience.
