STL Philosophy
Three major components; Science education is part of education. Science education meeting personal
aspirations. Science education related to society
needs.

Criteria for Science Teaching Initiate teaching from a social issue based scenario. Include cognitive, process, personal and societal
skills and values in chemistry/science teaching. Promote problem solving and decision making skills. Make the teaching student participatory. Base the assessment strategy on the goals. Enhance communication and cooperation skills. Ensure teaching relates to curriculum content
demands.

SCENARIO
This is a crucial component of the teaching material that identifies it as putting the learning into a relevant, societal context.
The scenario sets the scene for the learning and thus builds on the title of the material.
Where the title does not clearly give the issue of concern, the scenario illustrates the situation and elucidates the issue to be resolved.
Usually the more personal the scenario, the more the student can identify with the situation and hence find it more relevant.

WHICH MEDICINE IS BETTER – BLACK OR WHITE ?
Two days ago, Joe and Kim went to a birthday party. It was good, very good . The food was excellent.There was very rich, fruity birthday cake and all kinds of fizzy drinks to sample.
Yesterday , however the story was very different, Joe was unwell. He had stomach ache. His mother prescribed some fruit jelly drink. It tasted good, but Joey was not too sure he wanted to take it.
Kim was also ill. Her mother decided that it was better to take her to see the doctor. The doctor suggested charcoal tablets. Kim did not like the appearance of these black tablets, but she was presuaded to take them. Luckily, today both Joey and Kim are fine. Both recovered well. It seems the treatments worked.

CAN VEGETABLE OILS BE USED AS A FUEL?
Normal diesel is obtained from the distillation of crude petroleum. Any limitation in the supply of petroleum can thus have dramatic effects on the commercial life of a country.
If alternative ways could be found to produce diesel, this could help countries plan into the future, ensure that supplies of fuel can be obtained and hopefully providing a cheaper alternative than replacing the existing diesel engine with other mechanisms.
Fuels based on vegetable oils produce much less hydrocarbon emissions and practically no sulphur compound emissions. However, direct use of the oil itself is possible ONLY with modification to existing diesel engines. This is not a viable option.

Findings
The degree of ownership of STL is illustrated by teacher ability to create STL teaching materials.
The process of developing STL materials leads to permanent STL change in their general teaching approach.

Conclusions
. Teachers can understand the need for
relevance and express this in terms of a scenario-type teaching approach.
To ensure teachers permanent change towards STL more in-service experiences are needed after intervention.
