The teacher highlights what is relevant and the nature of the relationships between the elements. For example, the teacher might explain the compressibility of air in a bicycle pump by describing it as dispersed particles which may be brought closer or else by comparing it with the behaviour of a spring.

This process-centred approach could, for instance, offer the children experiments and investigations as starting points for acquiring conceptual knowledge with little or no direct teaching of concepts. In this case a conceptual structure is withheld. The onus is on the children to recall or construct a functional mental representation without reference to a teachers' description of one. Pupils might infer relationships in the topic under study and may be given an opportunity to test and revise their ideas.

2008 UCHCHTAR PAGAR DHORAN - OFFICIAL LETTER BY GOVERNMENT. KUTCH RAPAR Of course, other teachers might focus on a combination of these two approaches and develop scientific skills and conceptual understanding from in this combination. This mixed approach could be a balance or, perhaps, a compromise, between a product-centred and a process-centred approach, in which the teacher provides a partial conceptual structure and leaves the remainder for children to construct by inferring, hypothesising, or testing their ideas. It could encourage lessons where children do investigations with some features already identified by the teacher, and with some conceptual knowledge about the subject that enables them to appreciate the purpose of the activity. In contrast, it could encourage lessons without a clear purpose which mixed different types of activity, but did not develop either conceptual or procedure understanding exclusively.
