From the pre-intervention interviews with teachers, it appeared that teachers were separating subject knowledge from skills. Skills were linked with students involvement in the learning process, whereas knowledge was given by the teachers’ talk or the textbook. (i.e. ‘to teach general properties of metals’, or ‘skill to write ionic equations using the table of solubility’). In the interview, the teacher’s answers were not organised – most of their answers included fragments from the curriculum content and there was no balance between the subject oriented goals and more general goals (‘to teach logical thinking’, or ‘to understand the world around us’).

Social goals were linked mainly with environmental issues; only very few teachers mentioned goals linked to careers, or daily life needs. All teachers who recognised social goals, also emphasised the need to teach general skills in chemistry lessons (‘to develop a responsibility to protect the environment’, or ‘to understand possibilities for linking future life with chemistry’).
The manner in which teachers worded the goals illustrated their actual approach to teaching. The fact that less than 20% of goals were presented (orally in the interviews) in a student centred way was partly based on their understanding of student centred activities. Problem solving and decision making were not seen as components of student centred teaching. Student centred teaching was expressed in terms of solving numerical tasks, doing individual work with the textbook, or conducting an experiment. Communication between students was never highlighted. Problem-solving often appeared as a lower level thinking activity where there was little link with everyday life, if at all.
As Einstein put it, “the formulation of a problem is often more essential than its solution, which may be merely a matter of mathematical or experimental skill” (Penick, 1996). The findings indicate the need for suitable in-service for teachers. “Why” type of problems demand only one certain answer and do not develop the creativity of the learner. Teachers need be taught to look beyond the textbook and recognise wider problems.
After becoming familiar with the STL philosophy and the existing materials, the teachers started developing their own STL materials. The most difficult part was finding an issue or concern coming from the society and formulating it as a scenario – the starting point for STL teaching. Teachers gave mainly examples that illustrated scientific theories and their application. In the process of the development of the scripts, the following observations were noted :
- The teachers' skill to formulate the first draft of the scenario (a story leading towards a consequence map) depended on their previous perceptions about problem-solving situations - teachers who acknowledged socially derived problems in their interviews were able to find applications within the curriculum material.
- Teachers who stated, besides subject oriented goals, general and social goals for their everyday teaching, or presented large number of subject oriented goals a variety of ways, were easily guided to reformulate the scenario.
- The process of developing the consequence map encouraged teachers to overemphasise activities based on process skills and the scientific method.
- The emphasis in the scenario finally chosen by the teacher was linked with the quality of the consequence map created by the teacher. Well designed, socially derived scenarios indicating several strategies for seeing and solving the problem – the social issue based scenario.
- Poor consequence maps (teaching strategy leading to a simple concept map without decision-making in a social context) came from teachers whose priority for teaching was and remained to teach subject content and find, due to the intervention, more examples to show the application of conceptual science outside the school.
- The need for guidance decreased from workshop to workshop. Teachers picked up each others ideas and could interact orally, for example, in the consequence map formation. In so doing, teachers slowly moved in the direction of be able to create exemplary STL supplementary materials through their own ownership.
