Evaluating teaching styles: a different approach to bench-marking zoo education?
Andy Moss, Chester Zoo
Introduction
• We wanted to increase the amount of student-led ‘activity’ in our teaching sessions.
• We wanted to measure the success (or not) of this.
Baseline data collection (spring 2010)
Teaching sessions changed – more activities added (summer 2010)
Further data collection after changes were made (Autumn 2010)
Evaluation of success!
Research Design
Method
• Range of teaching sessions observed by me.
• Each session was divided into 5 main teaching ‘components’:
• Chalk and Talk
• Question and Answer (Q&A)
• Activity
• Artefact use (by Education Officer)
• Animal Encounter
The ‘components’
Chalk and talk:
Solely educator-led content, with or without the use of other media (such as photographs or video).
Tropical Rainforests
Capybara!
Question and answer: Educator-led questioning with one student (at a time) answering
Activity:
Either whole class or smaller group investigative activities where all students participate.
Artefact use: Demonstration by educator in whole-class situations. Does not include artefact use in activity components.
Animal encounter: Educator-led, whole class encounter

‘Explanation time’
From 2010 data…A Discovery!
So, we had another look in 2011…
Data from 2011….
6% of each session is spent on explaining activities
Explanation time average = 1 min 12 secs
So every time we add a new activity, we automatically add another bit of explanation time.
An average session…
Note that certain component types are intrinsically linked to others – Chalk and Talk with Q+A for example
Summary
• We have to be careful not to assume that changing what we do will have the effect we want!
• We wouldn’t have known this if we hadn’t evaluated it.
• Teacher feedback stayed the same throughout this study – so don’t just rely on teachers for your evaluation.
