Abstract

The aim of this qualitative research was to describe construction of algebraic factoring concept of high-ability students using APOS theory. The subjects of the research were high-ability students of SMPN 1 Surakarta and have been selected using purposive sampling. Data retrieved using think aloud method. Based on the findings and discussions, it can be concluded as follows. (1) In action stage: (a) subjects presented their knowledge by using pictures and words, and (b) subtracted the simple algebraic form by classifying the algebraic terms which have the same variables. (2) In process stage: (a) subjects multiplied the binomial using FOIL method, and (b) classified the algebraic terms that have same variables mentally and in the written form when they did the trinomial addition and binomial multiplication. (3) In object stage, subjects factorized the trinomial using procedural method and non-procedural method. (4) In schema stage, subject explained that the factor when multiplied by another factor will produce the factored trinomial and linked all the stages to formed a complete concept of algebraic factoring.

Abstract

The accurate understanding of critical thinking and mathematical creativity in solving the current problem is still difficult to standardize. These two thinking skills are indispensable to anyone who is studying mathematics, especially for Undergraduate Mathematics students who are studying Linear Algebra. However, the difficulties in critical thinking discourage students to think creatively and mathematically. In linear algebraic subject matter, many problems require critical reasoning. It goes without saying that the difficulties in various reasoning aspects critically cause other difficulties in developing creative thinking aspects. Further, mathematical critical thinking skills in solving problems require a background in understanding the concepts related to the problem faced. In addition, the failure to understand and connect between concepts in solving linear algebra problems makes it worst and difficult to critically and creatively think.

Abstract

The purpose of this research is to know the improvement of lecturer professionalism through the approach of lesson study, to see the increase of student interaction (with the students, teaching materials, lecturer), and to know whether the student learning result of the lesson study approach reaches the completeness. This research is a research of mixed method based on lesson study. Activities performed for each cycle consists of three stages: planning, execution, and reflection. The qualitative data is the description of the lectures professionality improvement with the quantitative is the increase of student interaction (with students, teaching materials, lecturers), and the result of studying Curriculum Review of Mathematics 1. The subject of this research was the students of Curriculum Review of Mathematics 1 in Mathematics Department UNNES year academic 2016/2017. The research instruments are a test, observation sheet, and questionnaire. The result of the research is the improvement of professionalism of lecturers of KBK Mathematics Education through lesson study approach for Mathematics Curriculum Mathematics 1 course, student interaction (with students, teaching materials, lecturers) increases, and learning achieves mastery.

Abstract

In the computer laboratory of Mathematics Department previously installed in the network of Novell Netware 5 operating system. But file sharing problem is when client upgrades the operating system. The server can not be accessed from the client. So finally the data management was decided not to go through the server. Another constraint is not being able to update regularly, so it certainly will be vulnerable to viruses. Within 1 month required to re-install twice because of virus attacks, malware, and others. The idea is to build a network which is server-based integrated, and make improvements on the server side system more effective and efficient, and safe from hackers or viruses. This research also contributes to the realization of green computing that supports the commitment of college conservation.
