ABSTRACT
Science teachers need to help students identify their prior ideas and modify them based on scientific knowledge. This process is called as conceptual change. One of essential tools to analyze students’ conceptual change is by using concept map. Concept Maps are graphical representations of knowledge that are comprised of concepts and the relationships between them. Constructing concept map is implemented by adapting the role of technological information and communication, as it is suitable with Educational Ministry Regulation No.68 year 2013 that stated the aids of multimedia to support learning process.Institute for Human and Machine Cognition (IHMC) has developed CmapTools, a client-server software for easily construct and visualize concept maps. This research aims to investigate secondary students’ conceptual change and cognitive learning outcomes after experiencing five-stage conceptual teaching model by utilizingCmapTools in learning Light and Optics. Convergent parallel mixed method is implemented in order to collect and assess conceptual change as qualitative data and cognitive learning outcomes as quantitative data. Sample was taken purposively (n= 22 students)at grade VIII in an International School Bandung, West Java. Conceptual change based on comparison of preliminary and post concept map construction is assessed based on rubric of concept map scoring and structure whereas cognitive learning outcomes is assessed based on normality gain in each cognitive level from C1 (remembering) until C4 (analyzing) aspect. Results shows significance conceptual change differences at 50.92 % that is elaborated into concept map element based on Novak and Gowin’s criteria such as prepositions and hierarchical level in high category, cross links in medium category and specific examples in low category. Strong correlation coefficient (rxy= 0.78) illustrates the implementation of five-stage conceptual teaching model by utilizingCmapTools in helping students to construct concept map is capable to improve secondary students’ cognitive learning outcomes in high category that is obtained based on normalized gain value <g = 0.86>. All of the results are supported with the students’ positive response towards CmapTools utilization that indicates improvement of motivation, interest, and behavior aspect towards Physics lesson.

INTRODUCTION A. Background
Students are viewed as goal-directed agents who actively seek information as it is stated based on Piaget (1978) that they come to formal education with prior knowledge, skills, beliefs and concepts that significantly influence what they notice about the environment and how to organize and interpret it in order to develop their thinking process. The process of transferring knowledge especially during teaching and learning science is focused on the completion of thinking pattern as stated on Educational Ministry Regulation No.68 year 2013 that involves nine main aspects such based on student-centred approach, interactive learning, network based learning, active learning, team-based learning, multimedia based learning,independent learning based on students’ needs, multidiscipline that integrate essentials knowledge and critical learning.
It is distinctly seen that the basic competence in the science content at secondary level deals with mastering scientific concept through describing, explaining, classifying, applying concepts and formulas, investigating through experiment based on students’ inquiry by using scientific method and communicating the results (Basic Framework and Curriculum Structure for Secondary Level, 2013). The basic competence is not only emphasizes on cognitive and psychomotor, but also affective domain such as showing scientific attitude that covers several aspects such as sceptical, objective, responsibility, creativity, critical, and openness in order to construct an individual with precious behaviour in real society. Basic competence as the minimum requirement must be achieved by each participants of education therefore mastering science concept at secondary level is one of the standard competences which are very essential to be developed and implemented as well as constructing good behaviour and implementing scientific methods. As a good teacher in the future, pre-service science teachers have to mastering scientific concept as the most fundamental aspect in transferring the knowledge to students.

In the implementation of science teaching and learning, those expectations are not promising. According to preliminary study that is conducted by the researcher that aims to figure out students’ problem in learning Physics, it is obtained that most of students find several obstacles and difficulties that describes by these statements:
1. Based on the average of mid-term Physics exam results, it is obtained that only three students or 13.64% pass the criterion standard at 80 whereas the rest of them or 86.36% have score below.
2. Majority of Students state that physics lesson is extremely difficult that covers 86.36% from total twenty two respondents whereas 13.64% feel also that physics lesson is difficult.
3. Several factors that underlineddifficulties in learning Physics such as low motivation in learning is stated by 9.09% of students as well as high achievement standards, inclusion of complicated formulas is stated by 18.18% of students, and mostly students thinkthat lack of learning media involvement is considered as main factor that covers 63.64% of total respondents.
4. Students cannot be independent to construct their own idea because they prefer to learn in group based learning as stated on questionnaire result that covers 59.09%.
5. Students’ motivation in learning is low that is indicated by their response of 72.73% that states willingness to review Physics material only while exam is announced as well as 22.73% of students review only if there is homework or group assignment.
6. The learning environment is not supported as stated by 77.23% students that feel boring to conduct the lesson.
Teacher interview is also conducted in order to figure out the reliability of students’ answer. Teacher realizes that insufficient time for students to construct their own concept is considered as main factor. The statement is align with students’ response because 63.64% respondents recognize that teacher never use

specific software in order to visualize concept. The role of teacher during instructional process is also dominant because teacher often uses speech with the lack of discussion process that is stated by 59.09% students. After doing self-reflection as stated on interview result, teacher thinks that inappropriate teaching method and media is considered as main factor of lower cognitive outcomes although remedial program is already conducted.
Two main problems underline students’ low achievement results based on preliminary study through questionnaire and teacher interview. These problems are classified into two; the inappropriate method and time for students to construct their own concept and the lack use of learning media in science teaching and learning process. In order to overcome those problems; method based on constructivism is essential in order to improve students’ independence in learning as well as thinking process. Students actively construct new information by making use of their prior knowledge and experience; therefore they construct their own understanding through the interaction with the physical and social environment (Liang and Gabel, 2005). Therefore, learning processdevelops students strongly held assumptions or ideas that are not consistent with accepted scientific understanding (Posner et.al, 1982). As a result, science teaching and learning must address these ideas.
Science teachers need to help students identify their prior ideas and modify them based on scientific knowledge. This process is called as conceptual change (Aydin and Balim, 2011). One of essential tools to analyse students’ conceptual change is by using concept map. Concept maps are graphical tools for organizing and representing relationships between concepts that is indicated by a connecting line through linking words (Novak and Canas, 2007). Concept map aims to answer focus question related with particular inquiry that the arranger seek to answer. Concepts and propositions are usually arranged in hierarchical structure; from most inclusive to exclusive concepts that represents knowledge organization (Canas, 2003). In particular period, teacher can analyse the existence of conceptual change by viewing prior knowledge, misconception, also the

acquisition and accommodation of new knowledge as maps are modified over time (Kern and Crippen, 2008).
Constructing concept map can be implemented by adapting the role of technological information and communication, as it is suitable with Educational Ministry Regulation No.68 year 2013 that stated the aids of multimedia to support learning process.Bennett, 2003 (in Qarerah, 2010) explains that as technology has become ever central to schooling, assessing students via technology-based methods will be increasingly required.With the help of ICT tools such as computer and software, complex Physics concepts can be visualized statically or dynamically i.e, graphic animation (Utariet al, 2013).
Institute for Human and Machine Cognition (IHMC) has developedCmapTools, softwarethat provide many capabilities for the creation of concept maps including highly intuitive, modeless editor and the ability to connect links into several trusted resources through serves (Canasetal. 2003). This software is designed based on client-server architecture that allows users to browse and share concept map that is stored in CmapServers distributed throughout the network by supporting synchronous and asynchronouscollaboration (Granados, 2003). Synchronous collaboration through CmapTools allows two users to construct concept maps simultaneously in spite of at different place, meanwhile asynchronous collaboration through CmapToolsis existed by the role of Concept Map sharing and Knowledge Soups that allow users to add or modify annotations and discussion threads (Canaset al. 2003).The knowledge soups that is stored in CmapServer allows students from distant schools to share claims (propositions) derived from their concept maps regarding with any domain of knowledge being studied (Canaset al. 2003).
CmapToolshas been used as effective tool to construct concept maps. A recent study by Carvhalhoetal. (2001) states that this software allows user to locate resources and web pages that are related to a concept, facilitating the addition of explanatory resources (pictures, videos, interactive flash) through the CmapServers. This software facilitates users by linking concept propositions through automatic linking words and enabling the navigation from one concept

map to another (Canaset al. 2003). CmapTools also provide beneficial features that allows user to easily construct knowledge model; a set of concept maps and associated resources about a particular domain of knowledge (Canaset al. 2003). Users can create concept map based on their conceptual understanding by establishing informative linking words and cross links, therefore publish and share them through CmapServers, social media or personal websites.
Based on the statement above, it is essential to implement research that able to investigate students’ conceptual change by optimizing the role of technology through CmapTools utilization. Conceptual change can be investigated under conceptual teaching strategy that involves concept acquisition process by modifying students’ prior conception. Therefore, the researcher has intention to conduct research entitles, “Application of Five-Stage Conceptual Teaching Model by Utilizing CmapToolsto AnalyzeConceptual Change and Cognitive Learning Outcomes on Light and Optics Topic.”

RESEARCH METHODOLOGY
A. Location and Subject
1. Research Location and Period
The research was conducted at International School in Bandung, West Java that applied 2013 Curriculum during instructional process. Data is obtained in the period of May until June 2014.
2. Population and Sample
Population is defined as generalization consists of objects or subjects that cover whole quality and specific properties; meanwhile sample is a part of whole quality and specific properties of population (Sugiyono, 2008:118)
The population of this research is all of students’ significance in conceptual change and cognitive learning outcomes that belongs to all secondary students in the school. Samplings are selected by purposive sample technique since researcher has the specific objective. The sample is all of students’ significance in conceptual change and cognitive learning outcomes under the topic of light and optics that consists of 22 students of VIII Grade.
B. Research Method and Design
1. Research Method
Method that is applied in this research is weak experimental method since only one treatment group is investigated without the involvement of control group (Arikunto, 2010). There will be no control group since it is not appropriate to compare method of concept map construction using prototype-based media with

mapping the preliminary and post concept map is required in order to analyze its relation towards cognitive learning outcomes that is assessed quantitatively through statistical means; therefore mixed method is developed in this research. Research variables are classified into two; independent variable (X) and dependent variable (Y) that is affected by the treatment process. Five-stage conceptual teaching model by utilizing CmapTools is the independent variable, whereas the dependent variable is students’ cognitive learning outcomes.
2. Research Design
Type of mixed method design that is applied in this research is convergent parallel that simultaneously collect both quantitative and qualitative data, merge the data and use the results to understand research problem. The datasets is analyzed separately based on its own indicator in order to make interpretation as to whether the results support or contradict each other that provides a convergence of data sources (Creswell, 2011).
Students’ preliminary and post concept map will be analyzed qualitatively
based on the scoring rubric that is developed by researcher and experts based on Novak’s criteria (1984, in Karakuyu, 2010) including concept map pattern based on Kinchin (1999 in Hay and Adams, 2000). Concept elaboration of each individual that is developed can be analyzed descriptively based on comparison of preliminary and post concept map construction. Qualitative investigation is also
concern on students’ ability in linking concept node to various resources by
utilizing CmapTools to understand their thinking process.
Quantitative analysis focuses on students’ cognitive learning outcomes that is obtained from pretest and posttest result by statistical calculation in order to investigate achievement in each cognitive domain; from C1 (remembering) until C4 (analyzing).
The interpretation concerns on quantitative measurement of the correlation between conceptual change and cognitive learning outcomes in order to analyze whether significance conceptual change can affect great cognitive outcomes.

accordance with the questions statement. The instrument analysis of objective test requires levels of difficulty, discriminating power validity and reliability.
1. Instrument Test Requirements a. Level of Difficulty
Good quality question has to be arranged in balanced; the proportion should not consist of whole easy or hard questions, since easy question will not stimulate students to spend more effort in answering as well as hard questions will make students desperate and doesn’t have any motivation to solve it (Arikunto, 2013: 222). Consideration of difficulty level is based on proportion of problem categories easy, medium and difficult. The formula to determine levels of difficulty is represented as follow:
.
� = � Where:
P= difficulty level
B = number of students who answer correctly N= Total number of students
(Arikunto, 2013: 224) Classification of difficulty level based on Arikunto is represented on Table 3.1 as follow:
Table 3.1Interpretation of Difficulty Level

Discriminating power is defined as the ability of particular question to distinguish students who classified as higher achievement and lower achievement. The amount of higher achievement students who can answer more particular questions compared to lower achievement means that those questions have positive discriminating power index (Arikunto, 2013: 226). Discriminating power index shows the scale from minus one until positive one, with the negative represents lower discriminating power index and vice versa. The formula to determine the discriminating power is represented below followed by criteria as seen on Table 3.2
DP =

…….. (3.3) c. Validity
Validity is defined as the extent to which the instrument measures what it is designed to measure that emphasizes not on the test itself, but on the result (Arikunto, 2013: 80). Validity which is used in this study is Construct Validity since each question item is formulated based on Cognitive Taxonomy. Arikunto (2013:83) describe construct validity measures thinking aspect based on logical; such as classified question item into cognitive dimension. The formula to determine validity is shown below followed by Table 3.3 that interprets the classification of coefficient correlation criteria.
=
−( ) ( )2
−( )2 2−( )2
Where:
= coefficient correlation or item validity
= sum of total score of all students for each question’s item = sum of total score of all students for whole test
N = total number of students
X = score of each student for each question’s item Y = total score of each student

Reliability is defined as the extent to which a questionnaire, test, observation or any measurement procedure produces the same results on repeated trials. In short, it is the stability or consistency of scores over time or across raters (Arikunto, 2013: 101). The split-half method using KR 20 equation is used to calculate reliability of the test by giving score one for correct answer and zero for wrong answer (Arikunto, 2013: 108).The equation is described as follow:
r
11= (
−1
)(1-
²)
Where:
r11 = instrument reliability k = amount of test item
∑pq = multiplication result of p and q s = deviation standard
The reliability interpretation represents on the table below.

B. Recommendation
Based on the findings of the research that has been conducted and concluded, there are several recommendations that necessary to be conveyed by the researchers as follow:
1. It is recommended for the other researcher to make a research about mapping conceptual change by utilizing CmapTools to analyze cognitive learning outcomes in others topics with higher level of cognitive level at evaluating (C5) and creating (C6) aspect by integrating it into project based learning.
2. Time allocation should be well-arranged in developing the conceptual teaching model so that efficient time with better result can be obtained. 3. Before designing or adapting a learning model, teacher should be able to
adapt with new characteristics of students based on their learning style.
4. Teacher has to concern with every students’ need in conducting treatment
therefore they will be not feel being pressured and learning atmosphere can be more enjoyable.
5. In conducting introduction of concept map that describes its elements such as propositions, hierarchical levels, cross links and examples, it is highly recommended to directly train students how to build concept map by using concept bank in order to stimulate students to classify and organize their prior conception. Concept bank can be made by using small papers that attached on the whiteboard.
6. For the researchers, it is suggested to build good communication with related subject teacher at school in order to overcome and minimize obstacles such as providing equipment for experiment and demonstration using local resources materials if school does not provide it.
7. For further researchers, it is suggested to distinguish characteristics between concept map and content diagram based on the inclusion of linking words and cross links.
