Cognitive Obstacle On The Topic Of Integral Among Mathematics Education Students Kartinah1,2*), Toto Nusantara 1), Sudirman1), Tjang Daniel1) 1) Universitas Negeri Malang Jl. Semarang No.5, Sumbersari, Malang, Jawa Timur 2) Universitas PGRI Semarang Jl. Sidodadi Timur No.24, Semarang, Jawa Tengah Abstract Obstacles are part of a students knowledge at a time that is generally reliable in solving a particular problem but this knowledge is then inadequate when dealing with a new problem. Obstacles are the knowledge that a person possesses and are generally sufficient in solving a particular problem, settling in the mind, but when faced with a new problem this knowledge is inadequate and difficult to adapt. Obstacles arises from the fact that certain concepts have a degree of complexity and necessary to recognize them in a particular order. For example, fractions are more complicated than all numbers, the student experience with operations on integers leads to the implicit nature that multiplications make numbers larger leading to a cognitive obstacle when encounter multiplications fractions less than one. Cognitive obstacles seem to be ontogenetic, epistemological, didactic and even cultural, according to their origins and the way they develop. Cognitive obstacles of Mathematics Education Students of Universitas PGRI Semarang were found when subjects solved the finite integral problem and assumed that the integral was integrable, whereas if the function in the integral is a function that can not be integrated.

High levels of anxiety can make student learning outcomes low. This research is aimed to analyze the relation of rote quran and yaumiah deeds to the level of math anxiety. Subjects in this study are junior high school students, who in addition to learning he also do memorization activities Al-Quran, other than that the students are also very maintaining yaumiahnya deeds, such as obligatory prayers and sunna, fasting sunah, read quran. This research was descriptive qualitative research. The researchers collected data through questionnaires of anxiety mathematics, sheet of memorization Al-Quran, and sheet of muttabaah yaumiah, then the researchers analyzed the data collected. The results are that: (1) Quantity of high zikr can reduce anxiety in learning mathematics, to the level of medium learning anxiety, and (2) obligatory prayers are always done and on time can affect the level of anxiety students in doing math problems, to the level of medium anxiety.

Interface Web Development For Analysis Of Item Response Theory With Mix Model Approach and Application On Bank Soal MGMP (a)Tika Clarinta Putri Utama, (b) I Made Tirta (c)Moh.Fatekurrahman (a)Department of Mathematics, University of Jember (b)Laboratory Statistics Department of Mathematics, University of Jember (c)Senior High School PGRI 5 Tegaldlimo, Banyuwangi Abstract The development of the world of education today is progressing very rapidly, the era of technology is increasingly modern, so that teachers must have adequate competence in every process of teaching and learning activities. One type of measurement often done in education are measurement of the students performance both for cognitive and effective aspects. These measures are extremely important therefore must use a good measuring tool and the results also easy to interpret. The measurement of students performance mostly use tests. Items response theory have evolved from traditional one to modern theories to apply more realistic models which are known as item response theory. However the use of modern test theory much rely on availability of the computer software. In this paper we report the development of a web-GUI interface that can be used to analyze polytomous responses, using Hierarchical Generalized Linear Models which will also contains theories and interpretations of the results. This Web GUI interface is expected to help teachers to understand and to do the analysis of polytomous responses more easily.

Ir. Sutami No. 36A, Surakarta 57126, Indonesia *amy.elnino[at]gmail.com b) Pascasarjana Pendidikan Matematika, Universitas Sebelas Maret, Jl. Ir. Sutami No. 36A, Surakarta 57126, Indonesia Abstract One of the 21st century skills is the mathematical literacy ability. The aim of this research was to describe the mathematical literacy ability student based on mathematical ability. This was qualitative descriptive research. The subjects of this research were three 8th grade students MTs Muallimaat Muhammadiyah Yogyakarta. The data collection was by test and interview methods. The research instruments was mathematical literacy test used 4 PISA questions and semi structured interview guidlines. The data were analyzed using a Miles and Hubermans concept, that was data reduction, presentation, and conclusion. To determine students mathematical literacy based on students mathematical ability, first step is grouping the students mathematical ability. There are 3 type of mathematical ability, high, average, and low mathematical ability. One person its was chosen of every group to be research subject, namely S1 (students with high mathematical ability), S2 (students with average mathematical ability), and S3 (students with low mathematical ability). Then was given a test mathematical literacy and interview. The analysis result showed that students can only answer of 2 question with level 2 and 4 mathematical literacy, whereas in question number 3 and 4 with level 3 mathematical literacy, student cant resolving.
