An analysis of scientifc knowledge in local wisdom concerning “Ta-Dang chili paste”

Abstract

 This study examined the knowledge and science contained in local wisdom about red eye chili paste. The results can be used to organize learning activities for science courses or additional science courses. It is a part of research on effects of science learning
management according to the STS guideline on red eye chili paste on the local wisdom awareness of Mathayomsuksa 2 students. Interviews with villagers (Open-ended) involved 5 persons, selected from 15 villages in Suthep Subdistrict, Mueang Chiang Mai District Chiang Mai Province were divided into 3 steps: 1st step, raw material preparation for making Ta Dang chili paste; 2nd step was making Ta Daeng chili paste and the 3rd step was the eating and storage process. Data from interviews with local philosophers to analyze scientif c knowledge by content analysis were divided into 4 subjects, consisting of physics, chemistry, biology and astronomy at the elementary and lower secondary levels.
The analysis of data from the interviews was found that Chili Ta Dang is a household dish that has been passed down since from
ancestors The raw materials used for making red eye chili paste consist of dried chili, garlic, shallot, shrimp paste, fermented f sh, peanut, and fish meal. It was found that scientif c knowledge was as follows. Step 1. Chili is a body of scientific knowledge about thermal energy. By transferring heat energy without an intermediary such as the radiation of the Sun to Earth. This is a form of energy that is important in the activity of living organisms. Step 2. Mingling, roasting, roasting and grilling; it was found that the fermentation of fermented fish, roasting or grilling, or roasting of garlic, shallots and nuts. Using the heat from the charcoal stove transfers heat energy as well as radiant heat. Step 3. Roasting f sh meal used a pan set on the stove with low flame. Heat is transferred by conduction and the heat will moves through the texture of the object from the high to lower temperature positions when is the transfer medium does not move. Step 4. To make red eye chili paste by pounding, it was found that a wooden mortar or stone mortar was used to pound Ta Daeng chili paste. By moving roughly up and down this creates a motion that is pulls towards the center of the Earth, ie gravity.
