Abstract

The aimed of this research was: 1) to know the difference of the average of mathematics learning result of students obtained through Cooperative Script model with the average of student learning result obtained through STAD type cooperative learning model in class VII class material in SMP Negeri 1 Banyumas, and 2) to know the average of mathematics learning outcomes which is better between students whose learning is obtained through Cooperative Script model with students whose learning is obtained through STAD type cooperative learning model in class VII class material in SMP Negeri 1 Banyumas. The population in this study is all students of class VII even semester SMP Negeri 1 Banyumas academic year 2016-2017 with the number of 162 students divided into 5 (five) class. The sampling technique uses cluster random sampling. Obtained Class VII A amounted to 33 students as experimental class and class VII B which amounted to 33 students as a control class. Learning outcomes obtained through the test in the form of a description consists of 4 items. Data were analyzed using two-t test and one-party test. Data analysis using two-party t test with 5% real level obtained by result of 1,999 and 2,602, < , so reject H0 and accept H1 which indicate that there is difference of mean result of learning of mathematics between them. Analysis of data using t-test one party with 5% real level obtained ttable = 1.670 and tcount = 2.602 turns < , so H0 rejected and accepted H1 which indicates that the average mathematics learning outcomes of students applied Cooperative Script learning model more both from the STAD type cooperative learning model. The result of t test analysis concluded that there is influence of Cooperative Script model to the result of learning of class VII in SMP Negeri 1 Banyumas

Abstract

This research is used to analyze the error profile encountered by STKIP PGRI Pacitan students in the course of Complex Analysis on the subject of PolarShape. The type of research used is qualitative descriptive. Subjects used as many as 2 students. Data collection methods used are test methods andinterview methods. The results of this study are on Misunderstanding, Transformation Errors and Process Errors. Misunderstanding is to assume thesymbol R = r when R ≠ r. Then assume that in calculating the root of the value of negative/positive just the same, even though the end result also remains the same. And it is often reversed between the values of x and y. Transformation error is inverted in determining x and y for cos arc formula. While the Process Error is unable to determine the magnitude of a special angle adjusted to the location of the point of z. weak in calculating the powers in the form of fractions. And wrong in drawing the z-point coordinates.

Abstract

The Mathematic Teaching and learning based informatic system is learning system implementing computerization technology as a learning tool in theteaching and learning process. This teaching and learning process in which it combines conventional method with the application practice has been constructed on the basis of the implemented curriculum in a college. The use of media in a teaching and learning process like computer as a learning tool will make the teaching and learning process more effective because it will create an interesting teching and learning process as well as stimulate the students’ creativity. In addition, the teaching and learning process not only as a tutorial qctivity but also it provides the implentation of the theories given. The Mathematic teaching and learning based informatic is done to know the comparison of problem solving in mathematic using Mathematic software application. The standardized process and the use of informatic are constructed based on the exsisting curriculum in order to control the quality of the learning proses and result.

Abstract

SMA Negeri 3 Kotabumi as an educational institution has the problem of still low student learning outcomes in Economics. Student learning outcomes in economic subjects, especially students of class X IPS 2 are still low. Determination of learning strategies in order to improve the quality of the process and learning outcomes can be investigated by classroom action research, because this study aims to overcome problems or solve problems in the classroom by taking action. One of the cooperative learning techniques is the Jigsaw technique. By implementing Cooperative Learning procedures correctly, it will be able to activate students so that they can improve student learning outcomes Classroom Action Research (CAR) is designed as a study material in the application of learning "Jigsaw" models to improve the ability to solve statistical problems in Economics. This class action research was conducted on students of class X IPS 2 of SMA Negeri 3 Kotabumi in the odd semester of 2018/2019, with 32 students consisting of 15 boys and 17 girls. This research has the benefit of increasing the ability of students to understand economics in this case students are trained to dare to express opinions or differ opinions on issues of presenting data. Learning with the jigsaw model can be presented to improve the ability to understand statistics in Economics. The study design was carried out in two cycles, starting with planning, implementing actions, observing, reflecting, and continuing with the next planning cycle. This research took place in September 2018 until November 2018. Based on the results of the study it was concluded that the Jigsaw model was able to improve the learning outcomes of Economics in class X IPS 2 students of SMA Negeri 3 Kotabumi in the academic year 2018/2019.

Abstract

Based on observations and experiences in class, it was found that writing is often a matter of less interest and there is less good response from students. Writing skills in the classroom are generally taught only when learning to write, writing skills should be integrated in learning or inserted in every learning in class. Problems that also arise related to learning writing skills in schools are the way to assess and target curriculum achievement which is only measured based on the results of written tests. Because of this, it is necessary to apply an authentic writing skills assessment model that is in accordance with various techniques and procedures. The subjects in this research were the process of teaching and learning activities between students and teachers / researchers of Class XII MIPA 1 of SMAN 3 Kotabumi, North Lampung Regency in the Academic Year of 2017 - 2018, amounting to 34 students. After conducting research and analyzing research data, the researchers concluded that the use of journal writing skills as an authentic assessment material in Indonesian Language Subjects Class XII MIPA 1 SMA Negeri 3 Kotabumi can improve student learning outcomes. This is evidenced by the increase in the percentage of Minimum Completeness Criteria that have been determined from the first cycle to the second cycle of 23.69%.
