Contents of Biotechnology in Technology Education Recognized by Experts

Abstract

The purpose of this study was to identify contents for biotechnology in technology education of the secondary school level. To accomplish this, this study employed literature review and modified Delphi survey. The modified Delphi survey that were conducted totally 3 times all consisted of structured items and the selected panel is composed of 33 persons. The results of this study are summarized below. Firstly, four categories of biotechnology contents were foundation of biotechnology, principles of biotechnology, utilization of biotechnology and impact of biotechnology. Secondly, the foundation of biotechnology included five sub-categories such as definition of biotechnology, history of biotechnology, terms related to biotechnology, characteristics of biotechnology (improvement & utilization of organism function, mass production), and technology related to biotechnology domain{bio-utilization technology (improvement of organism function - genetic manipulation, cell fusion, utilization of organism function - fermentation, culturing, cultivation, raising, breeding, bioreactor), biomimetics}. Thirdly, the principles of biotechnology included six sub-categories such as genetic manipulation, cell fusion, culturing, bioreactor, procedure of modern biotechnology(genetic manipulation or cell fusion →culturing→ bioreactor) and hands on activity corresponding to technology related to biotechnology domain. Fourthly, the utilization of biotechnology included five sub-categories such as the utilization in agriculture sector, the utilization in medicine sector, the utilization in environment sector, the utilization in energy sector, career exploration related to biotechnology. Fifthly, the impact of biotechnology included four sub-categories such as social impact of biotechnology, bioethics, biosafety(food, environment), the prospect of biotechnology.
