Dear Kwanchanok, I am reaching out to share some feedback on your disruptive innovation papers. Apologies for the delay. Its been a very hectic semester. Papers: The first paper on renewable energy is well written and draws on useful case studies. However, references need to be inserted into the paper. The second paper on bottom-up versus top-down innovation is well written and demonstrates effective analysis and application of useful case studies. However, the author should pay attention to having a clear introduction and conclusion. The third paper on innovation and the social structure is a very analysis that uses contrasting case studies. Overall, the author demonstrates strong potential if they are able to refine their essay writing by developing a better structure and use of references. .....Joy - you have good organisational and analytical thinking. However, to succeed next semester, I suggest you pay attention to essay writing structure and following academic conventions regarding the use of references. All the best next semester. Best Regards,
