Misconceptions are one of the most important and long-lasting studied themes on science education. It is because their nature is obstinate and settled as well as they corrupt students' understanding of science concepts. This study examines whether preservice elementary school teachers enrolled in biology teaching material research course changed positively on science teaching efficacy and correcting life science misconceptions when they used the handbook developed for this study. The handbook comprises 203 life science concepts surveyed among preservice teachers holding from advanced researches and arranged by 2007 Revised Science Curriculum. 107 preservice elementary school teachers participated in the study. Forty-six (46) of them were assigned to the experimental group and the other 61 to the control group. ANOVA was conducted for analyzing data. Science Teaching Efficacy Belief Instrument (STEBI) and the life science misconception test which was developed for this study, were administrated as assessing instruments for pretest and posttest. The experimental group, using the handbook, acquired higher scores in both tests on statistical significance level than the control group who were not using the handbook. The results indicate the handbook developed for correcting life science misconceptions for this study is effective in enhancing science teaching efficacy and correcting life science misconceptions.

For secondary school teachers who attended 'A Social Constructionism Science Teacher Training Program', we analyzed their processes of cognizance change as well as whether they put its results into practice in the field of education, so as to find out the efficacy of the program. 'A Social Constructionism Science Teacher Training Program' consists of three phases based on La main ${\grave{a}}$ la $p{\hat{a}}te$, a French experience-oriented science education program. In its first phase, a study of the philosophy of La main ${\grave{a}}$ la $p{\hat{a}}te$ was made, together with a search for examples of creativity education. In its second and third stages, real education programs were developed for designated themes and free themes, respectively, and then discussions were made. It was a ten-session program, with each session comprising a four-hour sub-program. All activities were both visually and orally recorded, while the participants were asked to write reflective journals for each class. An additional survey and interview were conducted six months later to check if the seven selected secondary school teachers put the results of the program into practice. It was found that changes may be made in the beliefs of teachers with the introduction of theories in teacher indoctrination, but the acquisition of practical knowledge that can be implemented in actual classes may be effectively secured by demonstrations and practice sessions. It was concluded that indoctrination should be conducted to lead participants to the level of practical planning from the level of mere belief so that the theories might actually be put into practice in the education field.
