Lesson Study in Introductory Biology Courses

Scott Cooper, Roger Haro, and Bill Cerbin

University of Wisconsin-La Crosse, USA

What is Lesson Study?Lesson study is a process developed in Japan, in

which a group of teachers jointly

design,

teach,

observe,

analyze,

& revise

a single class lesson, called a Research Lesson.

Develop Student Learning Goals

Design & Plan the Lesson

Teach, Observe, Gather Evidence

of Student Learning

Analyze Evidence & Revise Lesson

Re-teach, Study &Document Lesson

Biology lessons under development

Evolution – (2005)Survey students

before and after unit with questions about their understanding of how evolution works.

Will not ask if they believe in evolution, just if they understand it.

Ecology – (2005)Students analyze

data on temperature and precipitation and build ecological models to explain any trends.

These models are then tested by examining data from other sites.

Biology lessons under development

Genetics – (2005)Students are

assigned one of the 63 mutations that cause phenylketonuria and have to explain how that specific mutation could cause the disease.

Cells – (2005)Students analyze

data on how specific mutations in a gene in mice lead to susceptibility to ecstasy.

Similar mutations in humans have been linked to deaths in people using the drug.

Populations (2003-4)The Parsitologist’s Dilemma

Many countries have a problem with overpopulation which can lead to environmental damage and a lower quality of life.

These same countries also have a lower life expectancy due to infectious disease.

The “Parasitologist’s Dilemma” is that in curing a disease, one may contribute to overpopulation.

The Lesson

Students are broken into groups and assigned a variable to research.Give groups of students links to data on population

and environmental indicators in 3-4 countries.Students prepare a powerpoint slide with their

assigned variable for the countries. Students predict impact of curing heart disease or

malaria on the population of each country.These slides are presented in lecture as digital

posters.

Heart Disease is the leading cause of death in developed countries.50% of all deaths in US and Europe, typically

>50 years old.Caused by obesity, poor diet, lack of exercise,

diabetes, and genetic factors.

Clot in Coronary Artery

Malaria kills 2-3 million humansannually (90% of malaria deaths are in Subsaharan Africa)

Caused by Plasmodium parasite and transmitted by mosquito

Affects primarily children under age of five and pregnant women(Malaria kills an African child every 30 sec)

Malaria is a leading cause of death in less developed countries.

Assigned Variables

Student Work

Groups of students research assigned variable and turn in powerpoint slide as electronic poster.

These are graded and presented in the next lecture.

Students have a table to fill in the results of their colleagues research.

Adult Mortality

N= 60,424,000 ppl

R= 0.5% growth

G= RN = 302,120 ppl

N= 33,065,000 ppl

R= 2.4% growth

G= RN= 704,000 ppl

N= 293,028,000 ppl

R= 1.0 % growth

G= RN= 2,930,000 ppl

Info not available on the WHO website, but the death rate is 18 per thousand in the population

Males: 140 per 1000

Females: 83 per thousand

Will not have a large effect on adult mortality because malaria primarily effects kids

Will slightly lower adult mortality because malaria is prevalent in subsaharan Africa

Will not have a large effect on adult mortality because malaria is not prevalent in the US

Will lower adult mortality because HD is the leading killer of adults in developed countries

Will not significantly lower adult mortality because it is not a big killer of adults in Tanzania

Will lower adult mortality because HD is the leading killer of adults in developed countries

Wildness in 2050

Because the growth rate is positive in all three countries, the wildness will be depleted as a result of necessary

expansion.

ResultsStudent Engagement

Difficulty sympathizing with the malaria victims.

Tuned out when the environment and consumption were discussed.

Link between variables and population or environment were not clearly stated.

RevisionsIncluded more

pictures of children with malaria.

Decreased number of slides on consumption, and had students do research themselves.

Required statement of impact on slides students turned in.
