an innovative approach

Erickson (2003: 1155) believed that the qualitative research involves detailing
information about an everyday event and identifying the personal understandings of
participants in the event. A necessary example of an event is the implementation of a
teaching program, which can be studied by observing and documenting classroom
discourse and pedagogy. In this case, identifying and revealing the students’
meanings of school science and everyday science knowledge and the students’
awareness of knowledge should be considered critically while investigating what
students understand.
Quantitative methods are viewed as a tradition of emphasis on the
measurement and analysis of fundamental relationships between research variables
rather than the research inquiry process (Denzin and Lincoln, 1998: 8-9). The
quantitative method could be used to provide good information for qualitative
research, such as using computer assisted methods and low-level statistics to analyze
frequency counts. Also, the statistical measures, methods, and documents could be
used as a way of selecting a group of subjects from a larger population.
2. Methodology and Methods in Design of the Research
This research study used an interpretive methodology to develop a teaching
intervention to promote the eleventh grade student understandings about
photosynthesis in Thailand. Figure 3.1 shows developmental processes and
evaluating processes of the intervention as a research design. The development
process was concerned with the first research question, and evaluating process was
concerned with the second research questions presented in Chapter 1.
