Slide 2
• What is science?The systematic pursuit of knowledgeA way to find out true answers to
questions
• Why do we need science?Because common sense is often wrong
Important questions about science

Slide 3
1. Clearly identifying the problem
Needs to define what will be tested
2. Formulating a hypothesis
Based on observations3. Testing the hypothesisNeed to change one
variable only- all other variables must be kept constant
Need for a control group
Scientific method

Slide 6
• A scientist wanted to test the effect of talking to his plants on how they grew. He didn't talk to one group of plants, and talked for varying amounts to 3 other groups. After one month, he measured how tall the plants grew.
A. What was the experimental variable in this experiment?
B. What was the control group?C. What was the data he collected?D. What would be three variables that he would
have to control?

Summary
• On pieces of paper, write down what the main points you have learnt in this session are
e.g.• Science is a way to answer questions• Scientific method involves defining a question,
formulating a hypothesis and testing the hypothesis
• There are different ‘tiers’ of science publications• Scientists need to publish papers to progress in
their careers

Slide 12
• What are the issues for policy makers?
Look at scientific publications• What is it?
– primary research paper?– review article?– policy briefing/report?
• Who is it aimed at?• Does it reflect scientific consensus?• Does it give policy options?• Is it easy to understand?• How useful is it for policy makers?
Example of science publications: Malaria control

Science is the [intensive] human effort tounderstand, or to understand better thehistory of the natural world and how thenatural world works
• It is done through observation of natural phenomena, and/or through experimentation
• And its based on observable physical evidence.

What is Research?. The systematic process of collecting and analyzing information to increase understanding of the phenomenon under study
. Broadest sense of the word, the definition of research includes any gathering of data, information and facts for the advancement of knowledge
Many Special delicacies have one special ingredientResearch is the ‘special ingredient’ that makes science delicious

What is MLW?
• Medical Research Programme affiliated to University of Malawi, College of Medicine (the only medical school is Malawi) and funded by The Wellcome Trust, UK
When was it established?
• Established in 1995 originally as a Malaria Project but diversified in 2003
Case study 1: Medical Research in Malawi
Example projects
•HIV testing in children
•Iron Supplementation for children with HIV
•Comparison of two new Malaria drugs in children

Example: The Fight against Cassava Viruses
• Cassava is an important staple in many countries.
• Late 1980s, a new strain of cassava mosaic virus emerged.
• The Virus was highly powerful and aggressive
• Result - starvation in some districts of Uganda as many communities lost their principal source of carbohydrates.
• The government- demanded action.
Case study 2: Agricultural Research in Uganda
•Scientists responded by demonstrating that there was sufficient genetic diversity of cassava plants available for the national cassava breeding programme to mobilise.
•The outcome was to increase food security in Uganda. •Today cassava production is restored to former levels and able to generate a surplus

Example: Combating Drug Addiction
• An estimated 8.5% of Egyptians are addicted to drugs
• The most commonly used drug is Bango- a type of marijuana- but other drugs including heroin are also used
• The Center for Social and Criminological Research on Drugs carried out a study to design a national strategy to combat drugs and to provide treatment for drug addicts in Egypt
Case study 3: Social Research in Egypt

Case study 4: Health Policy Research in Ghana
Ghana Health Service Research Centres
• Primarily to generate information for policy consideration
– Work closely with programme implementers and policy makers in defining the problem.
– Design appropriate research methods for answering the questions
– Analyse and report appropriately
• Facilitate the policy dialogue
• Monitoring and evaluation of interventions
• Example projects:– Tobacco Use & Control– Strategies for Health Insurance for Equity in less
Developed Countries (SHEILD) in Ghana, South Africa & Tanzania
– HIV/AIDS– Malaria and Pneumonia

• Lack of sufficient funding • Insufficient trained
personnel• Negative attitude of the
public and policy makers towards science in general
• Lack of trust by communities?
• Poor infrastructure? • Brain drain?

Slide 25
Goal: developing country specific goals for theadvancement of science information in Africanparliaments
• Get into groups of approximately 5• Discuss why should we do research in Africa?• Discuss what strategy you would like to adopt in
promoting knowledge about science in our respective parliaments?
Share with the rest of the group
