1. The Michigan state university research a subject "henology", a study of recurrent nature activities. However, there are some limits that Phenology encounters, such as the higher cost and the useless of additional equipment as compared to the biological research. 2. The subject of Phenology is relevant to the climate change, such as fallen leaves, etc. Also, it's a complex subject too. 3. The Michigan State U. has a group of TAs (Teaching Assistants) who did the research on this subject, and they organized a "boot camp" in order to better study the nature of Phenology. 4. These TAs used different techniques and innovative methods to study the fallen leaves (does the half fallen leaves considered fallen leaves, etc.), the climate change and the cycle of this change. Later, they incorporated existing lab report and rewrite the existing one with their new thoughts and explorations. From the report, it's clearly to see that these TAs are potential to deal with such challenge problems. In addition, their exploration is not only based on the common sense, but also emphasized by their challenging ideas and techniques. Thus, their altitude should be rewarded. 5. From this study of Phenology, TAs also learn to build their confidence within their classmates and exert various methods to investigate the new field of knowledge. 6. The author suggests that we should provide more opportunities and rewards for our students because they do have the ability to handle the challenging subjects.
