Understanding the concepts and math reasoning ability of learners in schools has not developed optimally. This is because, teachers have not facilitate learners to be active in learning. In other words, learning done in schools has not been meaningful learning. One of the causes of mathematics learning tools used by educators has not supported the achievement of optimal learning objectives. The purpose of this research is to produce as learning device based on discovery learning mathematics on equation material and linear inequality that is valid, practical, and effective. This research is a development research using the Plomp development model consisting of initial investigation phase, prototype development or prototype phase, and assessment phase. The effectiveness data is obtained from the cognitive competence test sheet of the learner, observation sheet of students' affective competence and observation sheet of psychomotor competence of the learner. The results showed that the learning tools of mathematics developed were valid, practical and effective. In this journal only discussed increased understanding of the concept and the ability of mathematical reasoning of learners after use of learning devices based on discovery learning mathematics.Keywords: Discovery Learning, Conceptual Understanding and Reasoning Math Abilities.

The learning sets of mathematics used by educators greatly determine the achievement of learning objectives. But the fact that the the learning sets of mathematics used in schools have not supported the achievement of conceptual understanding and reasoning ability to the fullest. The purpose of this research is to produce the learning sets of mathematics based on discovery learning mathematics on equation material and linear inequality that is valid, practical, and effective. This research is a development research using the Plomp development model consisting of initial investigation phase, prototype development or prototype phase, and assessment phase. The effectiveness data is obtained from the cognitive competence test sheet of the learner, observation sheet of students' affective competence and observation sheet of psychomotor competence of the learner. The results showed that the learning sets of mathematics developed were valid, practical and effective. Learning outcomes of learners on cognitive, affective, and psychomotor competencies are effective. In this journal only discussed the effectiveness of learning tools of mathematics.Keywords: Discovery learning, the effectiveness of mathematics  learning  sets based on discovery learning

Student interest in learning is a very important factor in determining student success in learning mathematics. Various attempts were made by educators and educational researchers to increase student interest in learning. This research is a classroom action research model by Kemmis and Mc Taggart that aims to describe the application of Guided Discovery learning in optimizing students' interest in learning mathematics. The increase in students' interest in learning mathematics is also supported by the results of student achievement. The research data consisted of students' interest in learning mathematics, learning achievement data, and observations of learning outcomes. Data on learning interest in mathematics is obtained through a questionnaire, data on learning achievement is obtained through tests and data on the results of observations of learning achievement are obtained through observation sheets during learning. In general, the results of the study showed that the average student interest in learning mathematics at 83.93 reached the good category. The completeness of student achievement test results reached 83.87% of students achieving the minimum completeness criteria with an average student score of 85.61. The percentage of teacher and student learning outcomes respectively at 83.80% and 76.91% reached the good category. Therefore it can be concluded that the Guided Discovery learning model can be applied to optimize students' interest in mathematics learning especially by paying attention to the results of reflections from this study.

<p><em>research was motivated by the problem of the low learning outcomes of fourth grade mathematics. This is because mathematics learning is still teacher centered or still dominated by teachers, teachers tend to still teach mathematics in an abstract/symbolic way where the learning method is contrary to the cognitive development of students. This study aims to determine whether there is an increase in mathematics learning outcomes using the Guided Discovery Learning method in fourth grade students of SD 4 Adiwarno. The research was conducted in March-April 2020 in the fourth grade of SD 4 Adiwarno, Mejobo District, Kudus Regency as the research subject. The results of the study showed that the results of learning mathematics in the initial conditions were only 33.33% of students who reached the KKM. There was an increase in the first cycle of learning outcomes to 50% of students and in the second cycle increased to 94.4% of students who reached the KKM. The author suggests elementary school teachers to apply the Guided Discovery Learning method in learning mathematics in order to improve student achievement.</em></p>

It was hope that the improvement of mathematical reasoning should be reach by the students after the mathematics learning process, although it is not easy to reach. This study was carried out in secondary high schools through quasi experiment methods. The aim of this study is to describe: Students’ achievement after the learning process, and the difficulties factors on learning mathematics, through contextual teaching and learning based on constructivist approach. The conclusions of this study are: The improvement of students’ mathematical reasoning is quite good. There are also some positive improvements on students’ autonomous learning, students’ participation on the class discussion, the students’ ability on answering the question, and the students can explain to the class how to solve the problems. The obstacle of the learning process is the number of students in the class and the learning schedule. The alternative way to overcome this problem is by giving work sheets to be done as home work or some activities out of the class. It was hope that in the future, the math book should be revised, and being adapted to contextual learning with contextual illustration that is well known and well understood by the learners, so mathematical lesson will be attractive and easy to learn.Keywords: constructivism, contextual learning, mathematical reasoning

Mathematical Connection

This research is motivated by the low ability students' mathematical connections. Mathematical reasoning and connections are two basic mathematical ability that must be mastered middle school students. However, many students have problems and learning difficulties in solving mathematical problems. Through the process of mathematical connections, conceptual thinking and students' horizons will be broader, the students will have the skills to solve problems and make decisions. The problem of this research is " Is there any connection to the students' mathematics learning difficulties mathematical connection capability? ". Subjects in these criteria is a class XI student of SMK Kartika Accounting 1 Surabaya. Data obtained by questionnaire to measure students' learning difficulties and then given treatment for the provision of learning achievement test items to get valid data. Based on the analysis of data by using the formula Pearson product moment is known H_0 is no relationship difficulty learning mathematics against the ability to connect mathematics to the students of class XI AK-1 SMK Kartika 1 Surabaya while the H1 is no relationship difficulty learning mathematics against the ability to connect mathematics to the students of class XI AK-1 SMK Kartika 1 Surabaya. Of the formula product moment correlation can be obtained rhitung with significance level of 5% showed greater than the value rtabel = 0.344 and rhitung = 0.45; where r_hitung> r_tabel or 0.45> 0.344, it can be concluded that learning difficulties affect the ability of students' mathematical connections.
