Abstract

The purpose of this study is aimeds to (1) produce the mathematics lesson plan based on social arithmetic Problem Based Learning (PBL) in class VII in viewed from the aspects of validity and practicality and to know the potential effects arising from the development of the lesson plan, (2) describe the characteristics of the lesson plan based on social arithmetic Problem Based Learning. The method of the study was the development research according to the type of formative research by Tessmer. The stages of development were  Self Evaluation, prototyping and product. The subjects were VII.1 grade students of SMP Negeri 1 Muaradua semester 2014/2015 academic year, consistive of 31 people. Data collection techniques used were documentation, walk-throughs, observation sheets, and test results. Data were analyzed qualitatively and quantitatively. The results of data analysis showed that in the mathematics lesson plan based on social arithmetic Problem Based Learning (PBL) were valid, practical, and had a potential effect. The lesson plan had a valid learning in the content, construct, and language experts based on the results of the validation stage of the expert review and the prototype  test on a small group stage, while the practical lesson plan obtained  from the revised test results of one-to-one and small group. Potential effects of the lesson plan was  known from the results of the field test and the results of the students final test. The results of the students final test showed 45.16% of the students were is very good category, 32.26%  were  good category, and 22.58% fair category. From the result of observation, the percentage average of students’ activity was above 81,25% included in very good category.

Abstract

This research aims at (1)producing a valid and practical LKS (Student Worksheet) in discovery learning model in two circles intersection material in class XI, and (2) to find out the potential effect toward the learning outcomes from the development of LKS with discovery learning model in two circles intersections material in class XI MIA. The design ofthis research is a developmental study. The subjects of this research were 33 students of XI MIA 1 SMA N 1 Indralaya in academic year 2015/2016. The data collecting technique used were observation, test, and interview. The result of the researches were : (1) This research produced a valid and practical LKS with discovery learning model in two circles intersections material in class XI MIA withsome characteristics such as, (a) Contain the operational steps of discovery learning model, (b) Help students in finding the concept of two circles intersections model. (c) Make students active in learning. Being valid can be seen from the results of validator assessment, where the validator comments on the first prototype of LKS from content, construct, and language. Being practical can be seen from the results of  small group try out, in which it was based on analysis of the answer sheets of students, it was found that students were able to complete each steps there and students’ comments obtained from the sheets that stated the LKS given was easy to be done by students. (2) The developed LKS consisted of potential effect toward the learning outcomes from cognitive (knowledge), affective (attitude), and psychomotor (skill). In the cognitive domain 81.81% of students got score > 65, in the affective domain all of the students had shown an attitude of honesty and responsiveness shown by observations during LKS usage, as well as in the of psychomotor domain skills all of students had good skill that seen from the result of students performance.

Abstract

This study aims to generate trajectories of students in learning by using a comparison worth growing terraced paper of form informal toward formal shape. The method used in this research is the research design consisted of three stages, namely the preliminary, design experiments and retrospective analysis. In this study, a series of learning is designed and developed based on the notion of the learning process and approach PMRI. This research was conducted in SMP PGRI 1 Palembang by involving students in grade VII.2 totaling 30 students. This research produces Learning trajectory (LT), which includes three activities namely 1, activity starts from drawing two wake up the same but different size, measure each side at the wake and determine the corresponding sides to determine the ratio. Activity 2, the activity determines the relations between the two ratios to determine whether the two ratios is a comparison worth or not. Activity 3, resolve issues relating to the comparative worth of daily life-today. Results of the experiments showed that a series of learning activities that have been done to help improve students understanding of learning valued comparison.

Abstract

The research aims to produce a valid and practical LKS based on discovery learning model and also having potential effect. This type of research is Development Study of Design Research. The subject of this research were the first year students of SMP Negeri 7 Prabumulih academic year 2015/2016. The technic of collecting data have done with walkthrough, test, observation, and interview. The result of this research was produce two LKS that valid and practical based on discovery learning model with characteristic (1) Contain stages of discovery learning model, (2) Assist students in finding concepts on the subject of the angle, (3) make students being actively in learning process .Valid can be seen from the result of validator assessment where the validator comment on the first prototype of LKS from content, construct, and language perspective. Practical can be seen from the result of small group try out, which is based on  analysis of the answer sheets of students found that students are able to complete each stage there, and based on coment sheet of students found that LKS given were easy to used and understanded by students.  This devoloved  LKS which based on discovery learning model also have the potential effect toward result study. The result study from this research consisted of cognitive domain, affective domain, and psychomotor domain. In the cognitive domain, 91,66% of students got score more than 6,25, in the affective domain, all students have demonstrated a responsible attitude and respect that seen from the observation during LKS usage, and the psychomotor domain, all of students have been skilled that seen from the result of students performance.

Abstract

This research is motivated by the low mathematical communicating skills of junior high school students. The aim of this study is to know the differences in average score of mathematical communicating skills between the students once learnt using realistic mathematics education approach and students learnt using conventional approach. This research used a quasi-experimental method with non-equivalent control group design. The population used were all 7th grade students in SMP Negeri 2 Pagedangan, with two classes used as samples. This research datas are obtained from students’ scores in pretest and posttest. Based on the analysis of the research results, it is concluded that there are differences in the average score of matematical communicating skills between the students once learnt using realistic mathematics eduacation approach and conventional approach. The average score of mathematical communicating skills of the students learnt using realistic mathematics education approach is higher than the students learnt using conventional approach.

Abstract

This research aims to produce a TIMSS characterized math problems that are valid and reliable. The method of this research is Design Research. The sample of this study were 31 students of SMP Negeri 1 Inderalaya. The procedure of this study through the stages of Preliminary Evaluation and Formative Evaluation. Based on the results obtained 7 of TIMSS characterized with characteristics (1) using real-life contexts, (2) using characteristics of TIMSS, and (3) the type of problem-solving that problem logically and empirically valid  and reliable. Valid logically be fulfilled from the results of the assessment validator, where the validator comment on the terms of the content, construct, and  language. Valid empirically criteria for both internally for items validity and externally for the whole items validity. Items also expressed reliable with a high level of confidence as the test instrument through items with the analysis result reliability coefficient of 0,703.
