STS is more than just pure science knowledge.

Types of STS Programs

• SISCON (UK)--liberal arts science• SaTiS--STS modules• LoRST--integrating science into context

• ChemCom--start with STS issue• ALCHEM (‘70s)--technology contexts• STSC Chem (‘80s)--society contexts• Nelson Chem (‘90s)--epist. contexts

Decision Making Processes

• Identify and focus on the issue

• Formulate research questions

• Gather and organize evidence

• Analyze and evaluate evidence

• Resolve the issue• Apply the decision• Evaluate the

decision, the process and the action

Levels of Use for Perspectives

• Classify given perspective-statements

• Find +/- perspective statements and tally the number of each perspective

• Place personal value on statements• Make personal decision and state the

criteria used to make the decision• Participate in debate or townhouse
