Developing Science Teachers’ Understanding Nature of Science through New York Time’s Scientist at Work Science Blogs Pongprapan Pongsophon 1 Division of Science Education, Department of Education, Kasetsart University, Bangkok, Thailand
Why Nature of Science? A characteristic of Scientifically Literate Person, a person who can function in scientific and techno based society. NOS = Ideas about Science; what science is, how it works, who do it. People with acceptable views of NOS can distinguish science from non- science and Pseudoscience.
NOS in Science Curriculum Framework One of eight learning strands Integrating strand Teach along all content strands from P1-S6 ….However, a great amount of studies indicated that science teachers have unacceptable views of NOS and as a result deliver such naïve views to students.. They might have not been trained on NOS or might have been ineffectively.
Blog as a way to enhance NOS views among science teachers Part of the 21 st century life Can be so Educational and Entertaining at the same time In align with Social Constructivism; Reflecting and Interacting with the more experienced can enhance their learning
Research Purpose To examine the effect of “Scientist at Work” Science Blogs Activity on science teachers’ understanding of Nature of Science
Participants M.Ed. Students in Science Education, Kasetsart University All are in-service science teachers with min 2 of teaching experience Took a NOS course with the author in 2011 academic year Blog activity lasted for 6 weeks
Scientist at Work Blog Science blog written by scientists, initiated and host by Nytimes. “This blog is the modern version of a field journal, a place for reports on the daily progress of scientific expeditions — adventures, misadventures, discoveries” NYtimes..
Science blog activity
Instrument View of Nature of Science (VNOS) Form C Situational/open-ended questions Developed by Norm Lederman in 2002 Measure NOS views on 6 Aspects Distributed before and after the blog activity
Resultsn (N=22) NOS aspectsBeforeAfter Nature of Scientific Knowledge Tentativeness 57 Laws and theories 33 Scientific Inquiry Empirical Basis, Observation and inference 1320 Subjectivity 24 Creativity 1121 Scientific Enterprise Sociocultural Embeddedness 817
Suggestions The blog should not be too short so the teachers could take time to comprehend, familiarize, adjust and become a part of the culture. The explicit approach could have occurred in the seminar that follows blogging in which the instructor pointed out and discussed the aspects of NOS regarding teacher’s reflection.
