Teaching Approaches Used and Advocated

Respondents were asked to give ratings (1-5 scale using words) on the following questions:

  • I use the following approaches in teaching AE Design
  • I use student teamwork in teaching AE Design.
  • I would advocate changing the way the school teaches AED by changing the use of the following techniques

The detailed results are available on this Google-Docs spreadsheet.

 

Summary of Results

Approaches used:

  • Lecture is most common, followed by problem-based learning and guided design.
  • Architectural studio and modified study are never used in many cases.

Student Teamwork Used:

  • There is quite a spread in use in most cases - no consensus
  • Teamwork is used not much more than "sometimes" in most approaches, with a fair amount of use in Problem-Based Learning, and Guided Design.

Advocating Change in use of Techniques

  • There is considerable interest in increasing the use of all techniques except Lecture.
  • There is a marked interest in decreasing the use of lecture

 

Note on Statistical Significance of Results

Almost all the results showed a statistically significant difference from a null-hypothesis model centered on the middle term (3.0) of the 5-Likert values using a goodness-of-fit chi-squared analysis.  Those that weren't significant are shaded gray. 

Note, as always, that a significant result does not mean a big difference.  That is a matter of individual judgement, which is the reason the actual counts are shown.

Excel VBA Code for Likert Analysis

To test the significance of responses on a 1-5 scale ( commonly called a Likert Scale) produced as part of this sabbatical study I developed an Excel Macro to analyze the data and produce formatted output.  It is explained in detail on my webpage devoted to it with a link to download the code
