Exploring the Possibility of Using Inscriptions to Support System Thinking in Middle School Science Textbooks while Addressing Visual Concepts
This study explored how middle school science textbooks facilitated system thinking while addressing visual concepts. This study investigated the system thinking revealed in the text of textbooks, the ontological category of inscriptions and a comparison of the information in the text and the inscriptions. The textbooks addressed visual concepts using three themes: Structure of the eye and vision formation, Pupillary reflex and visual accommodation and Myopia and hyperopia. A high-level of system thinking was required to learn these visual concepts. Unmodified inscriptions are typically categorized as structure, but inscriptions can be modified through the addition of words and conventions or the use of multiple images to fit process. Theses inscriptions could enable to support the high-level system thinking revealed in the text. This study discussed the implication of using inscriptions in a textbook to support system thinking in science classes.OAIID:RECH_ACHV_DSTSH_NO:T201716244RECH_ACHV_FG:RR00200001ADJUST_YN:EMP_ID:A074908CITE_RATE:0DEPT_NM:μλ¬Όκ΅μ‘κ³ΌEMAIL:[email protected]_YN:NN
Exploring the Possibilities of Students` Conception Construction through Inquiry Activities in Middle School Science Textbooks
The purpose of this research was to explore how scientific inquiry activities in middle-school textbooks support students construction of scientific conceptions. We analyzed what forms of reasoning students do while exploring the questions in each activity. On the basis of this analysis, we then inferred the aspects of conceptions that students can construct through each inquiry activity. Subsequently, we examined whether the inquiry activities provide sufficient support for students to understand the conception targeted in each textbook subunit that contains the inquiry activities. As indicated in the results, activities with questions that elicit different forms of reasoning supported the construction of different aspects of conceptions. Inquiries that foster phenomenon-based reasoning supported constructing structure aspect of conceptions; inquiries that prompt phenomenon or relation-based reasoning supported constructing function aspect of conceptions; and inquiries designed to foster model- based or multiple forms of reasoning supported constructing behavior or mechanism aspect of conceptions. The textbook subunits usually feature inquiry activities that support the understanding of targeted aspects of conceptions. However, when the aspects of targeted conceptions are related to mechanism, the subunits typically present inquiry activities that support the construction of behavior aspect of concepts. The findings demonstrate that additional support other than inquiry activities is needed for students to understand targeted mechanism aspect of conceptions through case analysis. Our results shed light on the support offered by inquiry activities in the construction of scientific conceptions and suggest the necessity of cognitive support in successful science learning.OAIID:RECH_ACHV_DSTSH_NO:T201716245RECH_ACHV_FG:RR00200001ADJUST_YN:EMP_ID:A074908CITE_RATE:0DEPT_NM:μλ¬Όκ΅μ‘κ³ΌEMAIL:[email protected]_YN:NN
Pre-service elementary school teachers perceptional changes on STS through small group discussions in the general biology course
Understanding the relationships between science, technology and society and improving scientific literacy is the major goals of current science education. Many science education reform documents suggested the significance of improving scientific literacy through inclusion of decision making on real-life problems into science curriculum as well as understanding scientific knowledge and doing scientific inquiry. This study aims to explore the effect of the general biology course for pre-service teachers, especially focusing on the changes of the views on the relationships between science, technology and society and the perception on learning environments. Biological contents related to current controversial issues were lectured and small group discussions were practiced for two hours per week during one semester. Changes of students' views on STS were searched using the pre- and post-VOSTS questionnaire, and their perception of the learning environment was also analyzed using the CLES questionnaire. The results showed that the general biology course had positive effect on the participants' views on STS, and this course had personal relevance and gave a chance to communicate with each other through peer discussion

and designing curriculum through an investigation of the production of the 2009
science curriculum as well as its background. The science curriculum revision
conducted in 2009 reflects the spirit of the 2007 science curriculum; however, the
difference is that integrated science for the 10th grade was developed by scientists.
The characteristics of the 2009 revision are as follows: It highlights the converging
competencies of creativity and integrity as key competencies; it increases the
minimum number of science courses high school students have to complete; and it
allows some local autonomy of the school curriculum, which provides students with
more relevant and appropriate learning opportunities. The 2009 science curriculum
reflects a desirable direction for school science education reform. Nevertheless, the
tight schedule for the curriculum revision left not only the curriculum content
overextended and too difficult for students owing to the lack of reviewing
processes, but also school curriculum implementation is not guaranteed in
accordance with the national curriculum guidelines owing to a lack of
understanding of the new curriculum at local education offices and schools. It is
suggested that the system of curriculum revision, including the standard procedures
and the time frame, should be reformed. It is further recommended that participants
from various backgrounds, particularly teachers, should be authorized to provide a
voice in developing curricula

The aim of this study was to explore how a novice science teachers epistemological framing, characterized from her modeling instruction, evolved over time. We observed that the teachers framing changed over time, as she collaborated with researchers to plan, facilitate, and reflect on a series of lessons to support students small-group scientific modeling. We tried to understand how such experiences contributed to the changes in her framing. One 8th grade science teacher with two years of teaching experience participated in the study. The teacher collaborated with researchers for four months to co-plan and facilitate 18 lessons that included small-group scientific modeling. She also engaged in cogenerative reflection on the lessons for 13 times. All of her lessons and reflections were video-recorded, transcribed, and qualitatively analyzed for the purpose of the study. Our findings showed that the teachers epistemological framing, characterized from her interactions with students during modeling lessons, evolved during the study period: transitioning from an emphasis on students merely filling in blanks to prioritizing constructing personal reasoning and ultimately to focusing on the social construction of scientific reasoning. The teachers perception about what students are capable of changed, as she observed students during the modeling lessons, and this led to the shifts in her framing. Furthermore, through her engagement in planning, implementing, and reflecting on modeling lessons with researchers, she came to recognize the value of student collaboration in knowledge-building processes. These results can offer implications for supporting and studying teachers epistemological framing and modeling-based teaching by partnering with them.N

For this, I teach scientific model constructing class for science gifted students. I shoot video and record the voice for whole class and each group activity, have a face-to-face talk for selected group members, analyze the paper of activities. I reconstruct model creation and model developing process for each groups and each students, draw a influence that activity aspects of the students and role of the teacher affected modelling process based on those data. After analyzing, I find that discussion in the group contribute model creation and model developing process and developing process of each model changed according to the similarity between target model and first model. The more the students actively participate group activities, the more first model is diversified and final model is more elaborated. Also, the teacher influence model creation and developing process.OAIID:oai:osos.snu.ac.kr:snu2012-01/102/0000001728/4SEQ:4PERF_CD:SNU2012-01EVAL_ITEM_CD:102USER_ID:0000001728ADJUST_YN:NEMP_ID:A004819DEPT_CD:721CITE_RATE:0FILENAME:μμ¬κ΅μ‘μ°κ΅¬ 22κΆ2νΈ-265-290.pdfDEPT_NM:μ§κ΅¬κ³Όνκ΅μ‘κ³ΌEMAIL:[email protected]:

usual school class participation appear important factors that have strong parents affect the interactions relatively lower. Through this study, We identify two
things. Firstly, We must consider individual's inside factors for making animatedly the
interaction among the students. Secondly, We get considering factors that devise the
strategies for making the interaction animatedly. connectionOAIID:oai:osos.snu.ac.kr:snu2012-01/102/0000001728/3SEQ:3PERF_CD:SNU2012-01EVAL_ITEM_CD:102USER_ID:0000001728ADJUST_YN:YEMP_ID:A004819DEPT_CD:721CITE_RATE:0FILENAME:μμ¬κ΅μ‘μ°κ΅¬ 22κΆ2νΈ-291-315.hwpDEPT_NM:μ§κ΅¬κ³Όνκ΅μ‘κ³ΌEMAIL:[email protected]:
