One needs to build a theory by using an inductive model of thinking with logic as in grounded theory as Strauss and Corbin (1990) suggested that the development of a theory is the culminating aspect of the study grounded in data gathered. This theory can be presented as a logic diagram or a visual representation of relationship among concepts. As stated by Miles and Huberman (1984), a conceptual framework explains either in graphical or narrative forms the key factors or variables and the presumed relationships among them. As elaborated by Miles and Huberman (1984):
- Conceptual frameworks are best done graphically rather in text
- Expect iterations in these frameworks
- Develop simplified frameworks without arrows going in all directions
- In conducting data analysis, develop orienting framework, then add prior theorizing and empirical research to the framework.
The basis for conceptualizing the technology of food dehydration process’ as a source material for secondary school teachers is to provide an option window for them (secondary education teachers) to acquire skills and knowledge aside from the basic subjects they teach. Such an innovative approach provides added knowledge that not only enrich the teachers’ teaching skills but can also enhance their entrepreneurial skills as they can eventually venture into income generating businesses in food dehydration.
