KONTRIBUSI MATHEMATICS ANXIETY TERHADAP KEMAMPUAN AKADEMIK MAHASISWA PADA PEMBELAJARAN KALKULUS
Get PDFThis reseach comprehending on the relation between mathematics anxiety and the academic competence of the first level students. This research is constituted by the performance of most students of the early study program of mathematics education still feel anxiety when dealing with mathematical problems in the learning of calculus, the emerging discomfort felt by the students. The method of this research is survey with corelation technique. The use of this method is to see how strong and how far the influence of mathematics anxiety on the students academic competence. The population of this research is the students of Mathematics Department faculty of teacher training and education in Muhammadiyah University of Cirebon in the academic year 2016/2017. The sample of the research is purposive sampling which consists of 20 students who contracted differential calculus subject. The instrument used in this research is mathematics anxiety scala. The result of the research shows that there is a negative relation between mathematics anxiety and students’ academic competence. The mathematics anxiety gives a contribution 35% to the students’ academics competence, and 65% influenced by other factors not examined in this study
REGRESI LOGISTIK: MENAKSIR PROBABILITAS PERISTIWA VARIABEL BINARI
Get PDFPrediksi melalui suatu pemodelan statistic merupakan kekuatan utama dari analisis regresi linier. Akan tetapi, teknik ini mensyaratkan variabel dependen atau kriteria harus memiliki data kontinum dan sebaran skor yang normal sehingga ia tidak dapat digunakan jika variabel kriterianya merupakan variabel binary (nominal dengan dua kategori, memiliki skor 1 atau 0). Regresi logistik merupakan teknik yang tepat untuk menggantikannya. Alih-alih menghasilkan taksiran skor variabel kriteria, pemodelan dengan regresi logistik menghasilkan taksiran probabilitas munculnya peristiwa (skor 1) pada variabel kriteria. Taksiran probabilitas tersebut diperoleh melalui model regresi yang menghasilkan nilai odds dan log odds, yang pada dasarnya merupakan cara pengungkapan yang berbeda tentang kenyataan yang sama terkait taksiran probabilitas munculnya peristiwa dari seluruh kejadian dalam variabel kriteria.

ANALISIS MISKONSEPSI LITERASI SAINS MENGGUNAKAN THREE TIER MULTIPLE CHOICE TEST MATERI CAHAYA
Get PDFRecently mastery of scientific literacy for students has become the focus of education. The level of scientific literacy skills of students in Indonesia is low, which is influenced by misconceptions. So far, study on the development of diagnostic tests that uncover the misconception of scientific literacy is still limited, whereas it is much needed to improve the learning system in Indonesia. The result of observation and interview of scientific lesson in SMP Negeri 05 Semarang shows that students having difficulties in studying light materials and evaluation tools used by teachers are not continued to reveal misconception of scienctific literacy. The aims of this study to develop three tier multiple choice (3TMC) test with the scientific literacy aspect and to find the misconception of students' light scientific literacy. The research sample is class VIIIE and VIIIF with mix method of sequential explanatory strategy. The result of 3TMC test instrument with scientific literacy aspect which is developed which is 30 item where 25 items fulfill criteria with valid result, reliable, sufficient distinguishing, medium difficulty level while 5 grains are not used. The results of the interpretation indicate that the average learners have misconception of scientific literacy aspects of knowledge (A), science investigation competence (B), science as a way of thinking (C) and application of science to technology, society and environment. In-depth interviews were conducted on 7 students who experienced the highest misconception of scientific literacy. The result they experience misconceptions of scientific literacy indicators of light properties, viewing processes, eye defects and optical devices
