EFFORTS TO IMPROVE MATHEMATICAL CREATIVE THINKING OF SMK STUDENTS IN 2023 BY USING A PROBLEM-BASED LEARNING MODEL ASSISTED BY QUIZIZZ

,


INTRODUCTION
Education plays the most important role in influencing the development of the world in the future.Through education, humans are able to develop optimally and can compete well in the future by increasing their potential through the medium of education.Mathematics is a very vital subject because it is able to develop critical, creative, methodical and logical thinking skills for individuals who study it.This contribution of mathematics can be simple things such as basic calculations to complex things such as numerical analysis in technology.(Simanjuntak, 2023).
Mathematics lessons allow people to develop their mindset to think critically, creatively, logically and methodically.This is the main goal of learning mathematics.One of the strategies that can be used to help students improve their creative thinking skills is to make learning relevant to everyday life (Ed et al., 2023).
Every individual needs to have all four cognitive skills known as the "4Cs", which are critical thinking, collaboration, communication, and creativity.According to (Apriliani, 2016), having deep creative thinking skills in mathematics is important to overcome current problems in the era of globalization.This is due to the importance of generating new ideas and solutions to solve difficulties appropriately.In this regard, efforts have been made to develop abilities and skills in the learning process by improving the quality of learning in terms of understanding the material, using methods, utilizing supporting media, and creating a conducive classroom environment (Jihan & Hendriana, 2023).In accordance with Permendiknas Number 41 of 2007 concerning Process Standards, learning at every level of primary and secondary education must be interactive, inspiring, fun, challenging, and encourage students to participate actively.In addition, it also provides freedom for students to take their own initiative in releasing their creative ideas and stimulating the development of interests/talents and psychology (Aminy et al., 2021).
From the observation of the Mathematics learning process in class X SMK MALAKA, it was found that students' creative thinking skills in solving problems related to Statistics material were still low, with an average score of only 63.51.Students have not optimized their higher order thinking skills, especially in terms of creative thinking.There are four aspects of creative thinking skills observed, namely originality, fluency, flexibility, and elaboration (Miria et al., 2022).As a next step, further observation of students' creative thinking skills was carried out by conducting an initial test to evaluate students' understanding of Statistics material.Based on the results of the initial test, only 13 students managed to reach the math KKM score of 75, so the percentage of students who passed was 35%.Meanwhile, there were 24 students who had not reached the passing standard, with a percentage of 65%.These test results further underline the importance of improving creative thinking skills in all aspects for students.Mathematical creative thinking ability is considered as something important, but in reality it is still relatively low (Widiyanto & Yunianta, 2021).Many teachers are more concerned with results than processes, provide limited knowledge from textbook content, use passive teaching methods, and underutilize learning media (Indayanti & Sagala, 2023).
In this condition, the learning process becomes less effective because it focuses on the role of the teacher (teacher oriented).Students are only listeners and recipients of information recorded from the teacher.To improve students' creative thinking skills, the role of the teacher in managing learning has great importance.One of the learning models that can be applied to help the learning process is Problem Based Learning (PBL).
The application of PBL is very suitable for improving students' creative thinking skills.
Because through the PBL process, students are encouraged to develop divergent thinking skills in solving problems in mathematics learning materials, especially in Statistics materials.
Previous studies that have been conducted regarding the use of the PBL model show that this approach has a positive impact on increasing student activity and involvement in the learning process (Anwar et al., 2019).
PBL is learning that focuses on authentic and learner-centered problems (Subekti & Jazuli, 2020).Meanwhile, according to (Kreatif et al., 2021) problem-based learning model is to help students learn to solve problems, better understand what they are doing, and more actively gain knowledge.According to (Nitbani et al., 2020) problem-based learning model, learning activities must be focused on tasks or problems that are real, relevant, and presented in a specific context.Therefore, the role of learning media as a container in delivering learning messages to students.One of the learning media is important to support the success of education, which ultimately created the Quizizz application as a learning media.
The Quizizz application can be used easily if you have an adequate internet connection.
In order for Quizizz to develop into a competitive learning application amid the adaptation of the COVID-19 pandemic, continuous development is needed (Salsabila et al., 2020).Quizizz game is a game-based educational application that allows multiplayer activities to be carried out in the classroom and makes classroom exercises more interactive and fun (Mulyati & Evendi, 2020).If well prepared and in accordance with learning characteristics, the quizizz application is very helpful for teachers and students in the learning process.Not Creative Source: (Ikromi, 2018) To calculate the Percentage of Students (PoS) who are in the creative enough criteria, formula (2) is used as follows:

𝑃𝑜𝑆 = 𝑠𝑡𝑢𝑑𝑒𝑛𝑡𝑠 𝑤ℎ𝑜 𝑟𝑒𝑎𝑐ℎ 𝑡ℎ𝑒 𝑐𝑟𝑖𝑡𝑒𝑟𝑖𝑎 𝑎𝑟𝑒 𝑞𝑢𝑖𝑡𝑒 𝑐𝑟𝑒𝑎𝑡𝑖𝑣𝑒 𝑠𝑡𝑢𝑑𝑒𝑛𝑡 𝑥100%
A study is said to meet one of the specified success criteria if the results achieved show that at least 75% of students are at least moderately creative.

The initial mathematical creative thinking ability test was given to 37 students.

Discussion
The discussion of the results of this study is to find answers to the problems raised in There is a significant positive correlation of creative thinking skills assisted by quizzes in Statistics material, then these skills can be applied to students' daily lives because of the implementation of Problem Based Learning.The teacher acts as a facilitator and provides Based on the above problems, the researcher is interested in conducting a study entitled "Efforts to Improve Mathematical Creative Thinking of Vocational Students in 2023 by Using Problem Based Learning Model Assisted by Quizizz".METHODSThe approach used in this research is classroom action research (PTK) using the Kemmis and Mc Taggart model.In this study the researcher acts as a planner, action implementer, reflector, data collector and data analyzer, as well as debriefing the results of the research, helping schools carry out classroom action research (PTK).It also includes elements.The diagram of this research is based on the diagram developed by Kemmis and Taggart, in which there are four stages of action: planning, implementing, observing, and reflecting.The diagram is in Figure 1.below.Diagram of the PTK cycle model developed by Kemmis and Taggart This research was conducted in collaboration with the school mathematics teacher as a researcher and observer.The observer refers to the teacher activity sheet to check the learning process and the student activity sheet.The subjects of this study were class X students of SMK MALAKA in the 2022/2023 academic year totaling 37 people.The data collected include (1) teacher activity observation results and student activity observations, (2) test results at the end of each lesson, and (3) end-of-cycle test results.Data collection procedures in this study include validation of learning and research tools, observation, test Efforts to Improve Mathematical creative thinking of SMK Students in 2023 by Using a Problem-Based Learning Akbar, Hendriana the study of how the application of the problem-based learning model can improve creative thinking skills in students in class X-DKV SMK MALAKA.Based on the test data that has been obtained, there is an increase in test results and students' abilities in creative thinking skills during the application of the problem-based learning model in Mathematics in class X-DKV SMK MALAKA.Class X-DKV was the investigation conducted at SMK MALAKA.Students' mathematical creative thinking ability was evaluated before the implementation of PBL.The results of the initial creative thinking ability test showed a quite disappointing average score of 57.16 points.The mathematics teacher of class X-DKV of SMK MALAKA tested students' creative thinking ability after the lesson.In the problem-based learning model in cycle I, students obtained an average score of 63.51 on the mathematical creative thinking test, which showed a classical ability of 49%.In cycle II, the students' average score was 86.89, which showed a classical ability of 81%.As a result, students developed greater creative thinking skills.
