Abstract

Objek matematika sebagian besar bersifat abstrak dan sulit untuk dibayangkan sehingga banyak siswa yang kesulitan untuk memahaminya. Salah satu solusi untuk membantu siswa dalam hal ini yaitu dengan menggunakan alat-alat Euclid seperti penggaris, jangka, dan busur untuk menggambar objek geometri di papan tulis atau whiteboard. Namun, penggunaan alat-alat Euclid untuk menggambar terkadang tidak maksimal dikarenakan kurang efisien dan merepotkan. Akibatnya, banyak guru yang kemudian justru menggambar objek geometri tanpa menggunakan alat-alat ini sehingga gambar yang seharusnya membantu siswa memahami materi, justru malah membuat mereka semakin tidak paham. Penelitian ini bertujuan untuk menghasilkan alat yang dinamakan GeoKlik untuk mendukung kegiatan pembelajaran geometri. GeoKlik merupakan penggabungan alat-alat menggambar geometri Euclid yang didesain agar penggunaannya lebih fleksibel dan mudah sehingga guru maupun siswa dapat menggunakannya dalam proses belajar mengajar tanpa kesulitan. Pengembangan pada penelitian ini menggunakan model pengembangan 4D yang terdiri dari 4 tahap pengembangan yaitu define, design, development, dan dissemination. Penelitian pengembangan ini dilakukan di Program Studi Pendidikan Matematika FKIP UAD. Analisis data dalam penelitian ini menggunakan metode deskriptif kualitatif. Namun demikian, analisis data tetap melibatkan data kuantitatif dan perhitungan statistika sederhana. Berdasarkan hasil validasi ahli media, alat GeoKlik mendapat penilaian sangat baik dari ahli media dengan nilai rata-rata 4,79. Dari segi aspek desain, GeoKlik mendapat nilai rata-rata sebesar 4,78 dengan kategori sangat baik. Aspek keefektifan GeoKlik juga memperoleh skor sangat baik dengan nilai rata-rata 4,81. Sedangkan untuk aspek kepraktisan, GeoKlik mendapat nilai rata-rata 4,75 dengan kategori sangat baik. Respon yang diberikan guru dan siswa terhadap alat GeoKlik ini juga sangat positif dengan nilai rata-rata keseluruhan yaitu 4,79 untuk respon guru, sedangkan nilai respon rata-rata siswa yaitu sebesar 4,51.The development of the learning tool "GeoKlik" for geometry learningAbstractMathematical objects are mostly abstract and difficult to imagine so that many students have difficulty understanding them. One solution to help students, in this case, is by using Euclid tools such as rulers, rows, and arcs to draw geometric objects on the board or whiteboard. However, the use of Euclid tools for drawing is sometimes not optimal because it is less efficient and troublesome. As a result, many teachers then draw geometric objects without using these tools so that images that should help students understand the material actually make them even less understanding. This study aims to produce a tool called GeoKlik to support geometry learning activities. GeoKlik is a combination of Euclid's geometric drawing tools designed so that its use is more flexible and easy so that teachers and students can use it in the learning process without difficulty. The development of this study used a 4D development model consisting of 4 stages of development, namely: 1) Define 2) Design 3) Development, and 4) Dissemination. This development research was conducted at the Mathematics Education Study Program FKIP UAD. Data analysis in this research used the descriptive qualitative method. However, data analysis still involved quantitative data and simple statistical calculations. Based on the results of the media expert validation, the GeoKlik tool was very well rated by media experts with an average value of 4.79. In terms of design aspects, GeoKlik scored an average of 4.78 with very good categories. The aspect of GeoKlik effectiveness also scored very well with an average value of 4.81. Whereas for the practicality aspect, GeoKlik got an average value of 4.75 with a very good category. The response given by the teacher and students to the GeoKlik tool was also very positive with an overall mean value of 4.79 for the teacher's response, while the average response value of the student was 4.51.

Abstract

Many factors influence the low mathematics learning outcome. Teachers' attention, learning habits, and home study facilities may affect students' mathematics learning outcomes. Therefore, this research was conducted in order to determine whether there is a positive and significant relationship between teacher's attention, learning habits, and home study facilities with mathematics learning outcomes in even semester of the eight-grade students at SMP Negeri 7 kebumen academic year of 2016/2017. The population in this research were all students of class VIII SMP Negeri 7 kebumen in academic year 2016/2017 consisting of 3 classes with a total of 92 students. Random sampling techniques used to get the class sample and collected VIII H as a sample that consists of 30 students. Data collection techniques were conducted by questionnaires to the teacher's attention, learning habits, and home study facilities. They are a test method for mathematics learning outcomes. Test instruments used validity and reliability. Prerequisite test analysis using normality test, independent, and linearity test. Hypothesis testing data analysis using simple linear regression analysis and multiple regression analysis and correlation. The results showed that there is a positive and significant correlation among teacher’s attention, learning habits and home study facilities with mathematics learning outcomes with Fcount = 11,97 and Ftable = 2,98 so Fcount > Ftable, multiple correlation coefficient (R) is 0,76, and the multiple determination coefficient (R2) is 0,58. While the multiple regression equation is , relatively contribution (X1) = 45,51%, the relative contribution (X2) = 31,19%, the relative contribution (X3) = 23,30% and effective contribution (X1) = 26,40%, the effective contribution (X2) = 18,10%, and the effective contribution (X3) = 13,52%.

Abstract

The misconception is a condition where a student has a misunderstanding in comprehending a particular concept of what is meant to be. It raised when a student was gaining a new concept, namely in learning math, specifically in algebra operation. To know the misconceptions can be detected by using the Certainty of Response Index (CRI). This study aims to know the students' misconceptions and their causes in algebra operation of the 8th grade of SMP N 2 Bantul. This study is qualitative research. The subject of the study is the 8th grade of class C in SMP N 2 Bantul 2016/2017. The object of the study is the student's misconceptions in algebra operation. The data collection technique is in the form of a test based on the CRI and an interview. The data analysis used reduction, data presentation, and data inversion and verification. The results show that 53% of the students know the concept of algebra operation, 20% of the students only guesting, 15% do not know the concept, and 12% have misconceptions. Within the 12%, the misconceptions can be mention as follows (1) in the concept of formulating simple algebra and fraction algebra into its factors; (2) in the concept of the operation of addition, subtraction, multiplication, and division in the form of simple algebra and fraction algebra. The causes of this misconceptions are (1a) the student's low comprehension, (1b) the student's incomplete information, (1c) the student's low motivation to learn is not fully understood yet; (2a) the wrong intuition or opinion, (2b) The student's cognitive condition that remains in concrete.
