Secondary Biology Preservice Teachers' Conceptual Understanding Of The Chemical Processes Of Photosynthesis And Cellular Respiration, Edwin Estime Apr 2019

Secondary Biology Preservice Teachers' Conceptual Understanding Of The Chemical Processes Of Photosynthesis And Cellular Respiration, Edwin Estime

Doctor of Education in Secondary Education Dissertations

Photosynthesis and cellular respiration are important topics taught in most high school biology curriculum. These processes emphasize the interrelationship between the abiotic and biotic factors found in our world. The portrayal of these relationships to students is recommended by using crosscutting concepts such as Energy and Matter: flow, cycles, and conservation and Systems and System Models, which are discussed in this study. The conceptual knowledge of photosynthesis and cellular respiration has been studied widely amongst middle, high school, and college students. Before this study, only primary preservice teachers were examined for the conceptual knowledge of these biochemical processes. This dissertation ...

Television Lies: A Phenomenological Study Of Television’S Influence On Students’ Expectations Of High School Chemistry, Sarah Holcomb

Doctor of Education in Secondary Education Dissertations

High school students bring with them preconceived notions as to what types of laboratory experiments they will perform and content they will learn in chemistry class. Some of what students have learned about chemistry may have been derived from watching television in which chemistry is portrayed. There are many widely popular shows that portray science on television, and the narratives are over dramatized, simplified, or distorted for the sake of entertainment. Often the science portrayed on television is rooted in chemistry practices and thus influences students’ perceptions and attitudes of chemistry class. Though there is research in both fields of ...
