“…Researchers must properly analyze the appropriateness of the instruments developed to support an optimal research finding before implementing research begins. The tools compiled and developed must be valid, reliable, have good discrimination power with varying problem difficulty levels (Andrian, Kartowagiran, & Hadi, 2013;Manongko, 2016). An Instrument that generates records with good validity means a tool that can present essential knowledge concerning that which is being measured.…”

This study was motivated by the importance of mathematical connection ability for elementary school students. It was necessary to develop an instrument that suitable the indicators of mathematical connection ability to understand the students' mathematical connection ability. The goal of this research was to develop an appropriate mathematical connection ability instrument for primary school students. This study was applied using Research and Development. The participants were 34 third-grade students at an elementary school in Purwakarta, SDN Nagrikaler, chosen through purposive sampling. The instrument was an essay test consisting of six open questions about whole numbers. The indicators developed in composing questions were related to the mathematical connection ability, namely connections inter topics in mathematics, other subjects, and everyday life. The questions were made beforehand in the expert judgment, then tested to see the validity, reliability, difficulty index, and discrimination power index. The validity test analysis indicated that six items on the instrument were valid, the reliability of the test instruments was very high. Meanwhile, the difficulty level was classified as difficult and moderate, and the discrimination power was also categorized as good and very good criteria. Thus, those six developed questions could be applied to measure mathematical connections in the topic of operations of whole numbers for second-grade elementary school students and were suitable for further research instruments on similar subjects and variables even at different times and places.AbstrakPenelitian ini dilatarbelakangi oleh pentingnya kemampuan koneksi matematis bagi siswa sekolah dasar. Penelitian ini bermaksud mengembangkan instrumen yang sesuai dengan indikator kemampuan koneksi matematis untuk memahami kemampuan koneksi matematis siswa. Penelitian ini bertujuan untuk mengembangkan instrumen kemampuan koneksi matematis yang sesuai untuk siswa sekolah dasar. Penelitian ini menggunakan metode Research and Development. Partisipan adalah 34 siswa kelas III SD di Purwakarta, SDN Nagrikaler, yang dipilih secara purposive sampling. Instrumen yang digunakan adalah tes esai yang terdiri dari enam pertanyaan terbuka tentang bilangan cacah. Indikator yang dikembangkan dalam menyusun soal berkaitan dengan kemampuan koneksi matematis, yaitu koneksi antar topik dalam matematika, mata pelajaran lain, dan kehidupan sehari-hari. Soal-soal tersebut dibuat terlebih dahulu sesuai saran expert, kemudian diuji untuk melihat validitas, reliabilitas, indeks kesukaran, dan indeks daya diskriminasi. Analisis uji validitas menunjukkan bahwa enam item pada instrumen tersebut valid dan reliabilitas instrumen tes sangat tinggi. Sedangkan tingkat kesukaran tergolong sukar dan sedang, dan daya pembedanya juga termasuk kriteria baik dan sangat baik. Dengan demikian, 6 item soal yang dikembangkan tersebut dapat diterapkan sebagai instrumen untuk mengukur koneksi matematis dalam pembelajaran matematika pada topik operasi hitung bilangan cacah terhadap siswa kelas dua SD dan layak digunakan untuk instrumen penelitian selanjutnya pada subjek dan variable sejenis meskipun pada waktu dan tempat berbeda.

“…If the obtained data is not valid or is not appropriate with the facts, it might lead to the wrong conclusion (Arifin, 2017). The quality of research can be identified from the quality of arranged and developed instruments, in which it should be valid and reliable (Manongko, 2016). Other studies describe good instrument requirements as instruments that have high validity and reliability or meet psychometric requirements (Kartowagiran, 2018).…”

To generate high-quality research, a reliable instrument is required. This study aims to develop an instrument that can measure mathematical dimensions of elementary school students appropriately, for use in mathematics learning on spatial geometry. Each statement item in Mathematical Anxiety Instrument was developed based on 3 learning aspects, namely Attitudinal, Cognitive, Somatic. This study uses Research and Development (R&D) method with a quasi-experimental design on geometry topic. The sample is 100 sixth grade students in an elementary school located in Karawang Regency. The instrument developed in this study is in the form of a questionnaire with closed-ended questions. The validity test analysis implies that 23 out of 30 items on the instrument are valid. This data is supported by Cronbach's Alpha test results, where all item has reliability value higher than 0.80 indicating that the instrument being tested has a very high-test reliability. Therefore, 23 items out of 30 items were developed into instruments for measuring mathematics anxiety that applicable in Mathematics learning activities. Thus, it leads to the conclusion that this mathematics anxiety questionnaire can be utilized as an instrument for future research.
