“…Students also had a misconception in radicals as they were not aware that the domain of radical function is nonnegative real numbers. Based on similar finding by Ӧzkan [11], to get of the misconception of being negative in the square root, ones should stress out the domain of radical functions.…”

The transition from school to college mathematics courses involving advanced mathematics is a challenging task for many students. Undergraduate students in their first year are very often to experience difficulties in understanding mathematical concepts in a setting that emphasizes symbolic algebraic skills and graphing skills. Graphing skills are very important ability to grasp for students especially for whom mastering in mathematics. However, many references outlined that many students lack graphical skills. This study aims to investigate various students' errors in graphing polynomial functions which are considered as basic types of functions. To gather data on students' errors in graphing polynomial functions, two kinds of test are administered to first year students majoring in mathematics. The first test is directed to investigate students' prior knowledge on graphical skills learnt in school. On the other hand, the second one is aimed to gather information on students' graphical skills in higher order polynomial functions which have not been taught in school. The result reveals that many students make errors in graphing higher polynomial functions the same way as graphing linear and quadratic ones. Students' prior knowledge in graphing linear and quadratic functions essentially influences graphing skills in polynomial functions of higher degree.

“…Konsep-konsep yang ada dalam pelajaran matematika diajarkan mulai dari yang sederhana hingga yang kompleks (Dzulfikar & Vitantri, 2017). Ozkan (2011) mengemukakan bahwa pemahaman konsep yang rendah menjadikan siswa membuat pengertian sendiri terhadap konsep tersebut. Penguasaan konsep yang kurang atau kesalahan dalam memahami suatu konsep akan berdampak pada penguasaan materi berikutnya.…”

Logarithms are classified as new material for vocational students, where this material has never been taught in previous levels of education. A media in logarithmic learning are needed so that concept formation can be well received by students. This study aims to determine the validity and effectiveness of penselo media assisted by worksheet in facilitating the formation of students' logarithmic concepts. This is a development research with instruments used in this study are worksheet, media validation sheets, student response questionnaire, and field notes. Grade X students of SMK Telekomunikasi Darul Ulum are the test subjects in this study. The data in this study consisted of quantitative data and qualitative data. Quantitative data were analyzed using descriptive statistics, while qualitative data were analyzed using the stages of data reduction, data presentation and conclusion drawing. The results of the validation test on aspects of manual tools were 87.5%, language aspects were 75%, content aspects were 81.25% and other aspects were 81.25%, while student responses were 3.54 which met the very good category. It can be concluded that the penselo media assisted by worksheet is valid and effective in forming the initial concept of logarithm.

“…Dari penjelasan di atas dapat disimpulkan bahwa miskonsepsi adalah salah pandangan atau pemahaman tentang suatu konsep yang dimiliki oleh seseorang yang berbeda dengan orang tersebut konsep yang telah disepakati dan dianggap benar oleh para ahli. Ozkan (2011) mengungkapkan bahwa pendidikan matematika memiliki tempat yang baik dan penting dalam dunia pendidikan proses. Karena dengan strukturnya sendiri matematika mempengaruhi kajian ilmiah, teknologi sebagai metode dan metode sebagai hasil dari kehidupan ekonomi dan sosial.…”

In this study, this qualitative research aimed to describe the misconceptions students of junior high school in understanding characteristics of quadrilateral plane figure. The misconceptions instrument were administered to three students in 8th grade of junior high school. Students understanding were analyzed by misconceptions test with CRI (Certainty of Response Index) method with interviews. The misconceptions in understanding the characteristics of quadrilateral plane figure (trapezoid and parallelogram) were the main result of this study. Students showed the same misconceptions in understanding the characteristics of quadrilateral plane figure. The first, Students assumed the diagonal trapezoid isosceles is the only a pairs of same length segment. The second, students only known the parallelogram and rectangle shape are in the regular quadrilateral shape (if the parallelogram and rectangle has different position or irregular shape then it is no called a quadrilateral). In particular, the results indicated that the students had misconceptions in understanding characteristics of quadrilateral plane figure. The misconception occurs because the ability of student understanding is low or incomplete. So, the teacher should gave more problem and images for understanding the characteristics of plane figure.
