Keywords STEAM-Based Learning, Students’ Concept Mastery, Students’ Creativity, Light and Optics 1. INTRODUCTION The new paradigm of the 21st Century science education explores a wide range of possibilities that can foster students’ interest in science and creative convergent thinking. In Indonesia, education is supported by the National Curriculum of 2013. The purpose of using National Curriculum 2013 is to prepare Indonesian to be a creative, productive, innovative, affective, and also give a contribution to the environment, country, and the world. STEAM (science, technology, engineering, art, and mathematics) education has been implemented to enhance scientific literacy to use the integrated knowledge in the newly revised Korean science education curriculum (Kong & Huo, 2014). Recently STEAM education has emerged to develop human resource with creativity in mind and see and understand human society in the future. STEAM education is defined as education in which the students’ understanding and interest in related subjects such as science, technology, engineering, etc., foster of conversions of thinking and problem solving based on science and technology (Baek & Yoon, 2016). Hence, the purpose of National Curriculum 2103 of Indonesia and STEAM has the similarity which is to make the student be creative and implement the knowledge in daily life. Learning activities cannot be separated from the mastery concept. Ability in mastering the material can be seen from the mastery concept. Mastery concept is the students’ ability to understand the meaning of learning and apply it in their daily life (Shidiq, Rochintaniawati, & Sanjaya, 2017). Mastery concept is very important, Anderson and Krathwohl (2001) state that mastery concept can improve their intellectual skills and help them solve the problem they face and lead them to meaningful learning. Journal of Science Learning Article DOI: 10.17509/jsl.v2i1.12878 27 J.Sci.Learn.2018.2(1).26-32 Concept Mastery should be completed by creativity and other skills to enhance the quality of students. Deep understanding of a concept is highly needed to maximize the students’ creativity. Creativity has long been recognized as a powerful force in shaping human society progress and knowledge (Henriksen, Mishra, & Fisser, 2016). Creativity and innovation concern to the process of creating and applying new knowledge (Gurteen, 1998). Concept mastery not only should be completed with the creativity but also should be related or implemented in daily life. Light and optics is something that used in daily life. It is an essential concept that student is difficult to understand. Light and optics concept is a complex area for students and if it is not connected even implemented to daily life the student may not grasp the concept easily. The concept of light and optics is a relay on daily life such as camera, microscope, telescope, etc. The concept of the optic can be developed to make a valuable product in the future. This concept consists of science and mathematical explanation. Besides, it also could be integrated with technology, engineering, and art to produce a better product. Light and optics topic also in line with STEAM and National Curriculum 2013 of Indonesia because the topic makes the student be a creative one to make something useful in daily life. Thus, the present study proposed the research to see the effect of STEAM-Based Learning on Students’ Concept Mastery and Students’ Creativity in Learning Light and Optics. This research will analyze two variables they are students’ concept mastery and students’ creativity towards STEAM-Based Learning. 2. METHOD The research method used in this research is the Mixed Method. According to Creswell (2012) stated that mixed method is a type of research design which collects, analyzes, and mixes both quantitative and qualitative methods in a single study or series of studies to understand research problem. The quantitative data focuses on students’ concept mastery that is measured by an objective test in form multiple choices test while the qualitative analysis focuses on students’ creativity that is measured by the rubric of CPSS developed by O’Quin and Bessemer (2006). There are several sub aspects in CPSS rubric. After the students finish their project, the researcher gives a score to the project done by the student and find the average of the score. All data are analyzed separately based on the indicator and compared to obtain better understanding and interpretation regarding the effect of STEAM-Based Learning on students’ concept mastery and creativity in learning light and optics. Then, the researcher finds the gain to see the improvement of a student using STEAM Based Learning. Besides, the researcher relates the result of the concept mastery and creativity and find the relation of both variables. The location of this research was in Private Junior High School in Bandung. The school was using Indonesian Curriculum 2013 in the teaching-learning process. Bahasa Indonesia was the daily language used. The population in this research are 8th students in Private Junior High School. The researcher took one class in eight grades as the sample consist of 27 students. The sampling technique was convenience sampling technique. Fraenkel, Wallen, and Hyun (2013) stated that convenience technique is used because there is a group of individuals who (conveniently) are available for study (Fraenkel, Wallen, & Hyun, 2013). the research problem and question rather than only a method (Creswell, 2012). Based on the research method which has been adjusted to the research objective, therefore the research design which was implemented in this research is the convergent parallel design. The rationale for this design is to complete the understanding of research problem result from collecting both quantitative and qualitative data at the same time (Creswell, 2012). Besides researcher chose one class to make the researcher easier to conduct the research. The school has 3 classes of 8 grade. The researcher selected one class of 27 students because compare to the other classes, it was the available class and the amount of the student is not too much. In this research, the concept of Light and Optics is limited by Core Competence No. 3 and Basic Competence No 3.12 and 4.12 that are attached in Kurikulum 2013. The focus of subtopics that will be investigated by students such as (1) Light properties, (2) The image formation of lenses, and (3) Telescope. There are two types of instruments used in this research. There are objective test and rubric. First, an objective test based on Bloom’s Revised Edition was used to measure students’ concept mastery before and after implementing STEAM-Based Learning. It consists of Pre- test and Post-test. A pre-test is conducted to find the prior knowledge, while the post-test is conducted to identify whether the cognitive mastery is increasing or not. The cognitive level that will be tested in this objective test is C4 (analyzing), C5 (evaluating), and C6 (Creating). Concept mastery test consists of forty-one questions before judgment by experts. It is used to measure students’ concept mastery. After judging by the expert the objective is only twenty questions as a representative for each learning indicators. Then, the test was distributed to students in grade 8 as a test. The next step after conducting the test, the result is analyzed the objective test using ANATES software to measure the validity, reliability, difficulty level, discriminating power and distractor. Second, Creative Product Semantic Scale (CPSS) developed by Besemer and Treffinger (1981) was adapted to analyze students’ creativity. This analysis was used to assess students’ product at the end of the class. The Journal of Science Learning Article DOI: 10.17509/jsl.v2i1.12878 28 J.Sci.Learn.2018.2(1).26-32 adapted rubric of CPSS constructed by the author has been judged by two experts. 3. RESULT AND DISCUSSION The results show quantitative and qualitative data. The pre-test and the post-test are conducted to determine the students’ concept mastery before and after treatments. Qualitative analysis will describe the students’ product of the project at the end of the class. 3.1 Students’ Concept Mastery The profile of students’ concept mastery was obtained from objective test consisted of 20 multiple choice question that has been given as pre-test and post-test while implementing STEAM-Based Learning in chapter light and optics. The test item has been tested in term of validity, reliability, discriminating power, and difficulty level. Besides, it also has been judged by some experts and revised so it is appropriate to be used as a research instrument to obtain the data of students’ concept mastery. The improvement of students’ concept mastery is determined by the calculation of the normalized gain . Normalized gain is calculation processed through data of pre-test and a post-test score of students. The result is presented in Table 1. The average of the pre-test conducted before the implementation of STEAM-Based Learning is 43.14 and it is improving into 87.40 in the post-test. For the score of the students, the lower score of the student in pre-test is 15 and the highest is 70. Merely, the lower score of post-tests is 70 and the highest is 100. To get the improvement score, a normalized gain was calculated. Based on the result, the students’ concept mastery is improving with the normalized score 0.78 that assume as high improvement according to Hake (1998). In order to analyze the profile of students’ concept mastery, the improvement of each test item in every cognitive domain should be processed. The test item used in this research was developed based on the Bloom’ Taxonomy Revision by Anderson and Krathwohl (2001). There are three levels considered to be used in this research based on the basic competence that is used. Those are analyzing (C4), evaluation (C5), and creating (C6). The result is presented in Table 2. In order to analyze the improvement of concept mastery in each group, the test item was analyzed based on Table 1 The result of students’ concept mastery No Component Pre- test Post- test G Cate- gory 1 Participant 27 27 44.26 0.78 High 2 Average 43 87 3 Lowest Score 15 70 4 Highest Score 70 100 Figure 1 Concept mastery’s improvement of each group Table 2 The summary of students’ concept mastery based on Bloom’ Taxonomy Revised Edition Cognitive Domain Amount of Question Number of Students Average Score G Category Pre-test Post-test C4 8 27 52.8 88.4 35.6 0.75 High C5 7 27 36.5 89.4 52.9 0.83 High C6 5 27 33.3 82.2 48.9 0.73 High C4 C5 C6 C4 C5 C6 C4 C5 C6 C4 C5 C6 C4 C5 C6 1 2 3 4 5 Pre (%) 45.8 40.5 23.3 56.3 31 26.7 40 31.4 48 60 37.1 32 62.5 42.9 40 Post % 97.9 92.9 83.3 89.6 83.3 80 85 85.7 76 82.5 97.1 84 85 88.6 88 100 90 80 80 70 70 80 80 50 60 100 80 60 80 80 0 20 40 60 80 100 120 S co re Cognitive Level of Group Journal of Science Learning Article DOI: 10.17509/jsl.v2i1.12878 29 J.Sci.Learn.2018.2(1).26-32 the students’ group. The result of each cognitive domain in each group is presented in Figure 1. The result of STEAM-Based Learning implementation shows the average of pre-test is 43.35, meanwhile the average of post-test is 87.42. it is showing the improvement of concept mastery by processed the pre-test and post-test results the gain as much as 44.26. In order to categorize the students’ concept mastery improvement, the normalized gain is used. The result of the normalized gain is 0.78 which is categorized as a high improvement. Therefore, the hypothesis is accepted that STEAM-Based Learning improves students’ concept mastery. This result is supported by previous findings by Kim, Ko, Han, and Hong (2014) that is STEAM education influenced the improvement of academic achievement, creative problem- solving abilities, and scientific attitude. The research compared the control and experimental group in post-test and analyze it quantitatively and found out there is differences in the results. Another research by Kim and Park (2012) resulted that the STEAM Teaching Model is stimulated the students understanding related the activities in STEAM itself. Henriksen (2014) also stated in their research that STEAM Education significantly influenced the improvement of academic achievement, basic scientific process skills, and affective domain. This result showed the improvement of students’ assessment in content knowledge from 30% to 40%. The instrument was arrange based on Bloom’s Taxonomy revised edition by Anderson and Krathwohl (2001). There is three cognitive levels used in this research which is analyzing (C4), evaluating (C5), and creating (C6). The result shows that n-gain for C4 level is 0.78 which categorized as high, C5 level is 0.83 which categorized as high, and C6 level is 0.73 which categorized as high. The higher value of n-gain is evaluating (C5). The result shows the students are easier to checking, critiquing, testing something, or making a judgment. Light and optics are though in Indonesian Curriculum 2013 and it delivered when implementation of STEAM- Based Learning. In the process of the implementation, the students find a problem in learning light and optics. They said the topic is too abstract and many concepts deliver in this chapter. The strategy of the teacher to make the student understand the topic is to divide the class into groups and give them a problem related to the concept. The students are pro-active. They always ask the question outside the class if they do not understand the concept. The students have high curiosity makes the students give more attention while the implementation. There are steps of STEAM-Based Learning implemented in this research. There are 3 steps, those are 1) presentation of the situation; 2) creative design; 3) emotional experience. The first steps implemented at the beginning of the meeting until all the concept has been delivered to make the student understand the relationship between the concept and real life (Baek & Yoon, 2016). Compare to the other method, in Pratiwi, Rochintaniawati, & Agustin (2018) stated that the improvement of students’ concept mastery after implemented the multiple intelligent-based learning resulted in medium improvement as much as 0.61. hence, every method will have a different result. 3.2 Students’ Creativity In this research, students’ creativity is measured by telescope they made as a final project. Students’ creativity is assessed by using CPSS rubric adapted from Besemer and Treffinger (1981). Besemer and Treffinger (1981) suggested that product creativity is grouped into three creative dimensions which are novelty, resolution, and elaboration and synthesis. Each aspect has several criteria and also sub-criteria to make easier to assess the product of creativity. The criteria of novelty used are original, germinal, and surprising; for the resolution are valuable, logic, and useful; and the last, resolution and synthesis are organic, well- crafted, elegant, understandable, and complex. The result of creativity is stated in Figure 2. Figure 2 presents the result of every creativity dimension. For novelty dimension is 75.6%, resolution dimension is 77.8 %, and elaboration is 65.3 %. In order to see the whole profile of creativity in each group, the creativity in each group is necessary to be processed. The category of all dimensions is good. The students were more attractive and excited when they make the project. Every group has a good collaboration because every group consists of the students who have the same characteristic, thus they enjoyed when making the project. The result of the creativity in each group is presented in Figure 3. Based on Figure 3, every dimension in each group has a different result. Group 1 got 89% for novelty, 56% for resolution, and 73% for elaboration in average 73%. Group 2 got 100% for novelty, 89% for resolution, and 93% for Figure 2 Result of creativity dimension 76% 78% 65% 60% 65% 70% 75% 80% 85% Novelty Resolution Elaboration P er ce n ta g e Creativity Dimension Journal of Science Learning Article DOI: 10.17509/jsl.v2i1.12878 30 J.Sci.Learn.2018.2(1).26-32 elaboration in average 94%. Group 3 got 67% for novelty, 78% for resolution, and 100% for elaboration in average 82%. Group 4 got 89% for novelty, 56% for resolution, and 93% for elaboration in average 79%. The last, group 5 got 78% for novelty, 67% for resolution, and 73% for elaboration in average 73%. Creativity dimensions of a product consist of three aspects which are novelty, resolution, and elaboration and synthesis (Besemer, 2000). Each aspect has some criteria. The criteria of novelty are original, surprising, and germinal; for resolution are valuable, logic, and useful; for elaboration and synthesis are elegant, well-crafted, organic, complex, and understandable. Each criterion of creativity is used to assess students’ creative product as the final result of STEAM-Based Learning implementation. Overall, the students’ creative product is categorized as good (Henriksen, 2014). This result is supported by research conducted by Kim, Ko, Han, and Hong (2014) that significant improvement was found in students’ creativity by using STEAM-Based Learning compared to the control group. It happens because in STEAM-Based learning consist of the creative process in every step of the implementation. In line with the research of Kim, Chung, Woo, & Lee (2012) that STEAM leads to processes that result in creativity, innovation, and continued growth and exploration of the world. Another research supported this result conducted by Kim, Ko, Han, and Hong (2014) that there is significant improvement found in the creativity and scientific interest in elementary students. 3.3 The Relation between Student’s Concept Mastery and Creativity In order to compare and relate the result of students’ concept mastery and creativity, the charts of the comparison between student’s concept mastery and creativity is made. The chart is shown in Figure 4. The relation between students’ concept mastery and creativity could be seen through the cognitive level of concept mastery and dimension of creativity. Here, the level of cognitive used was analyzing, evaluating, and creating. The dimension of creativity used here was novelty, resolution, and elaboration and synthesis. Anderson and Krathwohl (2001) stated that analyzing is finding, integrating, something, and organizing something or breaking material into its constituent parts and detecting how the parts relate to one another and to an overall structure or purpose. Evaluating is checking, critiquing, of testing something or making judgments based on criteria and standards. Creating is designing, constructing, planning, or making something or putting elements together to form a novel, coherent whole or make an original product. The dimension of creativity used here novelty, resolution, and elaboration and synthesis. Besemer and Treffinger (1981) stated that novelty is the newness of the product, new techniques, new process, and another element of newness. Resolution is how well the product does what it is supposed to do. Elaboration and synthesis consider product’s presentation style. There is a similarity between the cognitive level and the dimension of creativity. If we relate the level of cognitive and the dimensions of creativity, we can see that analyzing is closest to resolution. Both analyzing and resolution are to make something in order, relate to one another, and how something does what it is supposed to do. Evaluating is closest to elaboration and synthesis which is testing or judging something or product and how to describe it. Creating is closest to novelty which is constructing or making something new. Figure 3 Result of creativity in each group 1 2 3 4 5 Novelty 89% 100% 67% 89% 78% Resolution 56% 89% 78% 56% 67% Elaboration 73% 93% 100% 93% 73% Average 73% 94% 82% 79% 73% 0% 20% 40% 60% 80% 100% 120% P er ce n ta g e Dimension in Each Group Journal of Science Learning Article DOI: 10.17509/jsl.v2i1.12878 31 J.Sci.Learn.2018.2(1).26-32 Based on the explanation, the students’ concept mastery and creativity relate each other. It is proven with the pattern of the relationship between students’ concept mastery and creativity result. The data of the students’ concept mastery and creativity is shown in Figures 4. From the data, it is clear that every cognitive level paired with a dimension of creativity will be the same. The higher the value of C4, the novelty value will be high. as well as elaboration and C5 also resolution and C4. It also can be related also with the implementation of STEAM-Based Learning where the students more excited to prove something whether it is right or wrong and in the presentation session, they were so excited to explain the product. It is proven by Kim and Park (2012) stated that the STEAM improves the student understanding and interest. This condition is proven with the value both of evaluating and elaboration and synthesis are higher than other cognitive level and dimension of creativity. Different from the result of analyzing and novelty which gains the lowest value. The students are hard to analyze something and making the product different with the example given. 4. CONCLUSION Based on the result of STEAM-Based Learning implementation that has been conducted, STEAM-Based Learning effect significantly to Students’ Concept Mastery and Creativity in Learning Light and Optics. There are some other conclusions gained: Implementation of STEAM-Based Learning on light and optics concept improves students’ concept mastery. It can be noticed by the gain of pre-test and post-test score that is 0.78 which included as high improvement category. Implementation of STEAM-Based Learning can be used to profile students’ creativity through the project. Students’ creativity is assessed based on CPSS rubric focuses on tree dimension which is novelty, resolution, and elaboration and synthesis. Students’ creativity on novelty gain 76%, on the resolution is 78%, while on the elaboration and synthesis is 69%. All creativity is categorized as good.
