Coat colour in cats:- genes?- environment?- genes + environment?

Using clickers to test knowledge

Coat colour in cats

1. Genes

2. Environment

3. Genes + Environment

Coat colour in cats - genes or environment or both?

The Siamese coat pattern is a heat-map of the animal’s body

A mutated gene for an enzyme that controls dark coat colour works most effectively at low body temperatures

The enzyme, a tyrosinase, is responsible for producing the dark pigment, melanin

Generating discussionGenerating a discussion - Smoking and health 3

In the USA:

• 444 000 people die each year due to smoking related illnesses.

• Smoking causes 1 in 5 deaths in America annually.

• Smokers in the USA:

• 26.2 million men (21.5% of adult males)

• 20.9 million women (17.3% of adult females)

Smoking and health 3

A life-long cigarette smoker increases his/her risk of dying at age 55 by 2.5 times compared with a non-smoker and is twice as likely as a non-smoker to die at age 75.

Possible explanations:

Compared with smokers dying aged 55, the smokers who die at age 75 are:

1. Less susceptible to smoking-related diseases

2. More likely to die of something else

3. Both of the above

Smoking and health The smokers at age 75 are:4

1. Less susceptible to smoking related disease

2. More likely to die of something else

3. Both of the above

Consolidate understanding through practice

Subject:

• Types of clinical study

Consolidating understanding:

• Identify types of study from papers published in clinical journals

Example:

• A study to to examine the evidence as to whether or not taking vitamin or mineral supplements prevents the development of age-related macular degeneration (AMD).

Evidence-based practice for optometrists

A study to to examine the evidence as to whether or not taking vitamin or mineral supplements prevents the development of AMD.

1. Case study

2. Cross-sectional survey

3. Case-control study

4. Cohort study

5. Randomised controlled trial

6. Systematic review

How can clickers be used effectively to promote deep learning?

1. Get students on your side and put them in charge of their learning

2. Design questions that reinforce and progress the understanding

3. Allow students time to discuss with each other

4. Don’t just give the correct answer!!
