Abstract

Teaching materials that are too monotonous and have no color in the LKPD which are currently used by many students in schools make students less interested in seeing and even reading them. The purpose of this study is how to design the development and feasibility of student worksheets (LKPD) Mathematics using a contextual teaching learning model on the subject of the Himpunan. Can the developed student worksheets (LKPD) use the contextual teaching learning model on the subject of the Association. This research is a development research (RnD) using a 4-D model, namely the definition stage, the design stage, the develop stage and the dissemination stage. However, it was modified to be 3-D because the application media did not reach the deployment. The research instrument is the RPP feasibility test questionnaire and the LKPD feasibility test questionnaire. Based on the results of expert validation, from the results of the final assessment on RPP validation by the three experts with an average of 4.4 with a percentage of 88.6%, namely the Very feasible category. The results of the final assessment on LKPD validation by the three experts with an average score of 4.5 with a percentage of 87.2%, namely the Very feasible category. Based on these data, it can be concluded that the development of Contextual Teaching Learning (CTL)-Based Student Worksheets on the subject matter of the Association is very feasible to use.

Abstract

The aim of study is to investigate tourists’ perspective on English verbal communication of the tour guides at pulau banyak.. This study used descriptive qualitative method in analyzing the data. Verbal Communication consist can be found and use on tourist guide to tourist foreign.  And to reason for the used of communication between researcher and tourists . Tourist Guide are people who provide assistance, information about cultural, historical and contemporary heritage about people organized tours and individual client in educational pleces, Tourist attraction, religious and historical sites, museum,  and in places from other significant interests. And Tourist is person travelling in a certain period in place he visits( Yoeti : 1999 ). Therefore, the tourist need someone to help in giving detail information releted to the place, know as tour guide. That have good verbal communication to tourist understand what tour guide talk about it. it was found that the first tour guide produced (Fair ) for Accuracy, (Fair ) for Fluency and (Very Good  ) for Comprehensibility . and the second tour guide produced (Fair) for accuracy, (Good ) for Fluency and (Very good ) for Comprehensibility. It means the most dominant types of verbal communication that used on the conversation by both tour guide is   Comprehensibility.

Abstract

The formulation of the problem in this study is whether the flipped classroom learning model with a realistic mathematical approach is effective on the mathematics learning outcomes of students at MTs Azizi Medan T.P 2020/2021. The purpose of this study is to find out whether the flipped classroom learning model with a realistic mathematical approach is effective on the mathematics learning outcomes of students at MTs Azizi Medan T.P 2020/2021. The research design used in this study was a pretest posttest control group design. Sampling was done randomly. The instrument used in this study was a test (pretest and posttest in the form of a description). Based on the results of hypothesis testing using t-test at a significant level of 5% or 0.05 and degrees of freedom dk , obtained a value with a value of . Based on the increase test (N-Gain) that there is an increase in the experimental class by 0.5 and in the control class by 0.12. Therefore, it can be concluded that the flipped classroom learning model with a realistic mathematical approach is effective in improving student learning outcomes for class VIII MTs Azizi Medan T.P 2020/2021.

Abstract

In this study, the problem is that the students' interest in learning Mathematics is still low. This study aims to determine whether the application of the CTL (Contextual Teaching and Learning) learning model can increase interest in learning mathematics in VII students of SMP Muhammadiyah 8 Medan TP 2018/2019. This type of research is classroom action research (CAR) with the method used in this study. is qualitative. The subjects of this study were students of class VII-B SMP Muhammadiyah 8 Medan, totaling 34 students. The object in this study was the use of the CTL (Contextual Teaching and Learning) learning model to increase interest in learning mathematics for class VII-B students of SMP Muhammadiyah 8 Medan T.P 2018/2019 The data collection techniques in this study were observation, questionnaires and tests. Observations were used to obtain the results of observations of student interest in learning, the results of questionnaires of student interest in learning and tests were used to obtain the level of mastery of student learning and the implementation of the process of learning the subject matter of algebra using the Contextual Teaching and Learning model. The data analysis techniques used in this study were observational analysis, questionnaire analysis, learning completeness analysis and classical learning completeness analysis. The results showed an increase in students' interest in learning mathematics by using the Contextual Teaching and Learning model on the subject of algebraic forms in class VII-B students of SMP Muhammadiyah 8 Medan T.P 2018/2019. The improvements that occur are (1) in the early stages the average is 55 with a classical learning completeness percentage of 14.70%, (2) in the first cycle the observation average is 66.32 with a classical learning completeness percentage of 44.12%, (3) in the second cycle the average observation became 83.4 with the percentage of classical learning completeness 88.23%.

Abstract

This research is a quantitative research that aims to apply the Indonesian Realistic Mathematics Education (PMRI) approach in learning mathematics as an effort to improve the mathematics ability of high school students. Low math skills directs researchers how to improve math skills through the application of the PMRI approach using everyday life problems in learning mathematics. Mathematical skills in question are students' abilities in mathematics proficiency tests through conceptual understanding, reasoning, and problem solving exercises. This study aims to improve junior high school students through the PMRI approach in the teaching and learning process supported by appropriate learning tools. To achieve this, the method used in this study is a quantitative method with an experimental design. Meanwhile, to measure student responses and activities, this study used a qualitative approach. Quantitative data were analysed using statistical analysis techniques, namely t-test, while qualitative data were analysed using descriptive analysis techniques. The specific objective to be achieved in this research is to provide adequate teaching materials using the PMRI approach which innovatively supports the improvement of the mathematics abilities of junior high school students. Based on data analysis and hypothesis testing, there is a significant increase in students' mathematical abilities when using the PMRI approach rather than using the conventional approach. Furthermore, student responses and activities during the learning process with the PMRI approach are included in the specified category

Abstract

This study aimed to analyze the types of meaning and the description of meaningwords/phrase/sentencess used in the Mantra Pawang Hujan. Geoffrey Leech Theory was applied in this study. A descriptive qualitative research was appliedto analyze the data. Source of data was in the form of spoken form of Mantra Pawang Hujan from two local pawang. They were transcribed into the written form which consisted of word/phrase/sentence.Data were collected through observation, depth interview, and documentation. There were 23 word/phrase/sentence as data in Mantra Pawang Hujan 1, and 17 word/phrase/sentence in Mantra Pawang Hujan 2. After analyzing the data, it was found 6 types of meaning appeared in Mantra Pawang Hujan 1, namely; conotative meaning, social meaning, reflective meaning, thematic meaning, collocative meaning and affective meaning. Meanwhile there were 4 types of meaning found in Mantra Pawang Hujan 2, namely; conotative meaning, social meaning, conceptual meaning and affective meaning.The meaning of words/phrase/sentences communicated by the two pawang is not far from the actual meaning. Mostly, the expression used by pawang 2 is the real meaning, because the words/phrase/sentencess are pray, praises or a compliment to the Almighty God and also based on Quran.
