I Mind Map Application Needs Analysis to Improve Students’ Mathematical Concept Understanding Ability

The ability to understand concepts is the mastery of the material in which students recognize, know, and are able to re-express concepts in a form that is easier to understand. However, students’ conceptual understanding skills still tend to be low. So it takes teaching materials that integrate these abilities. For this reason, this study aims to analyze the need for teaching materials based on mind map applications to improve students’ conceptual understanding skills. A mind map is a mind map in the form of a diagram that visually describes ideas, concepts, information, or other things. This type of research is descriptive qualitative. The research was conducted in one of the public junior high schools in Yogyakarta. The subjects in this study were 32 students of class IXA. Data collection techniques used interviews, concept understanding ability tests, and preliminary study questionnaires. While the data analysis technique uses the Miles and Huberman model which consists of data collection, data reduction, data presentation, and drawing conclusions. The results showed that teachers had not implemented mind map-assisted learning, students’ conceptual understanding abilities tended to be low, students were interested in learning using mind map applications because students could develop ways of thinking and make them more active during learning

Studying mathematics is not only made into rote material, but students need to understand existing concepts, the ability to understand concepts cultivate can be interpreted as a result taken from a series of events or objects that are very important in thinking and reasoning (Akbar, 2018;Aldahdouh, 2020;Alfakih, 2021;Al-Salem, 2020).This ability can be used to find abstract ideas that are often found in mathematics subjects, so this ability is very important for students to have (Afsah, 2021;M. Ali & Amin, 2022;Al-Jubouri, 2021;Widdowson & Barbour, 2021) Students are said to have the ability to understand a concept if it is able to explain a definition in its own words according to important properties being able to mention examples and not examples and be able to use concepts in solving problems (Anoum dkk., 2022;Demina dkk., 2022;Firman dkk., 2022;Ilham dkk., 2022;Najeed dkk., 2022;Safitri dkk., 2022).However, students' conceptual understanding skills still tend to be low (Güler & Çelik, 2022;Hellstrand dkk., 2020Hellstrand dkk., , 2020;;Lo, 2017;Ruthven, 2020) So that the ability to understand students' concepts can increase.a teaching material is needed.The example of teaching materials that can be used is the i-mind map application.
Mind mapping is a learning method designed by mapping information in graphical form.Mind mapping can be mapped using branching lines of images (Alamri, 2020;Barakabitze, 2019;Meirovitz dkk., 2022), as well as keywords that are related to the main concept or idea (Arnott, 2014).Based on observations made by researchers at one of the public junior high schools in Yogyakarta, it is known that that this application has not been used, even though this application has advantages that can make students better understand the concept of the existing material (Almarzooq, 2020;Browning, 2021;Burke, 2020;Y. Chen, 2021;Elareshi dkk., 2022).This is in accordance with several studies using mindfulness that have been carried out where maps are able to improve students' conceptual understanding abilities (A.Ali dkk., 2022;Alzubaidi dkk., 2022;Aslanoglou dkk., 2022;Basavarajappa dkk., 2022;Vasquez & Bennett, 2022).Because of these advantages, the researcher intends to conduct research to determine the analysis of the need for using mind map applications to improve students' conceptual understanding abilities.

RESEARCH METHODOLOGY
This type of research is descriptive qualitative (Agee, 2009;Barnett-Page, 2009;Beneito-Montagut, 2011;Booth, 2016;Borrego, 2009).The research was conducted in one of the public junior high schools in Yogyakarta.The subjects in this study were 32 students of class IXA.Data collection techniques using test interviews and preliminary study questionnaires.Interview technique was conducted with mathematics subject teachers to analyze teacher responses regarding students' conceptual understanding abilities and needs regarding teaching materials.The test technique is used to determine the understanding of the initial concept of students' abilities in solving math problems.The form of the test used in this research is in the form of a description question consisting of 4 questions.The student response questionnaire technique aims to analyze student responses regarding teaching materials using the i-mind map application for learning mathematics.The data analysis technique uses a model.Miles and Huberman which consists of data collection, data reduction.presentation of data and drawing conclusions.

RESULT AND DISCUSSION
In this section the results will be presented.research obtained from interviews.observation, concept understanding ability test, and preliminary study questionnaire.Based on the results of interviews with mathematics teachers at Darul Hikmah Pakem Junior High School in Yogyakarta, it is known that the teaching materials used are in the form of printed books as a reference for learning mathematics.Furthermore, the results of observations showed that students tend to be passive, feel bored quickly and most students still think of mathematics as a difficult subject.This is supported by the results of the questionnaire distribution of the preliminary study which showed that 47% of students liked mathematics and as many as 87% considered mathematics material to be difficult.Results Others were also obtained based on the distribution of students' conceptual understanding ability tests presented in Table 1 2 shows that as many as 34% of students showed high students' conceptual understanding abilities, while others were in the low category.For this reason, it can be concluded that the students' conceptual understanding ability still tends to be low.This is supported by the results of interviews conducted with mathematics teachers that students' conceptual understanding skills still tend to be low.According to him, when given questions that are different from the examples, some students will be confused and think the material is different from what was taught.In fact, sometimes the questions only differ in numbers and only require students' understanding of the concepts in the material being taught.Understanding this concept means students will still understand the material being studied even though it is presented on a different question model.Therefore, students are said to have a high understanding of concepts when they are able to work on non-routine questions given by the teacher.
The low ability of students to understand concepts requires teachers to develop an application to facilitate it.Will but the teacher does not yet have an application idea to be developed in the class.So that based on the results of the preliminary study questionnaire, it is known that all students have used mobile devices and 87% of students are very interested if learning is carried out based on game applications.Furthermore, students are very interested if the application used is I Mind Map.I mind map is a diagram that visually depicts ideas, concepts, information, or other things.Each concept idea or information is in a mind map box that is connected in an organized manner with lines (links).The description of the mind map that the researcher made is presented in  1 is an example of a mind map made by researchers as an illustration to students regarding teaching materials that will be applied by researchers.From the results of the preliminary study questionnaire, it is known that almost all students are interested in learning using the application.In addition, according to students, learning using the i mind map will be able to make it easier for students to understand the concepts of the existing material.
Based on this information, the researchers concluded that teaching materials based on the I mind map application were able to improve students' understanding and that the I mind map teaching materials could stimulate students' understanding and needed to be developed.From the results of the analysis of student needs obtained from the distribution of questionnaires to each class IX student, it shows that students are interested in using teaching materials based on the I Mind map because students can develop their way of thinking and make them become active.
Several studies have also shown the use of the mind that improves students' mathematical concept understanding abilities (Chijimatsu dkk., 2022;Chiuppesi dkk., 2022;Fraile dkk., 2022;Fu dkk., 2022).In fact, the active role of students during learning is further enhanced by the application of mind mapping (Q.Chen dkk., 2022;de Ruiter & van Loon, 2022;Deshpande dkk., 2022;Fraile dkk., 2022;Hiraike dkk., 2022).Because of the advantages that exist from the application of mind maps, this study concludes that teaching materials that integrate mind map applications need to be applied to improve students' conceptual understanding abilities.

CONCLUSION
This study concludes that teachers have not yet implemented mind map-assisted learning, and students' conceptual understanding skills tend to be low.students are interested in learning using mind map applications because students can develop ways of thinking and make them more active during learning.This research is still in the preliminary study stage, and will still be continued at the design, implementation and evaluation stages.
