Based on the data of the last three years, that the value of students under 70 reached 50%. The purpose of this study is to find out how much contribution: (1) motivation to learn on student learning outcomes in digital simulation courses ptik study program FKIP UBH Padang City, (2) attitude of learning to the results of learning in digital simulation courses ptik study program FKIP UBH Padang City, and (3) learning motivation and attitude of learning together to the results of learning students in the course Digital Simulation study program PTIK FKIP UBH Padang City. This research is quantitative research with correlational type. The research population was 39 students. The sampling technique uses the Total Samplingtechnique, which means that the sample has the same number as the population. Data on learning motivation and learning attitudes were obtained through questionnaires using the  Likertscale, while data on student learning outcomes in Digital Simulation courses were obtained from the final score of the even semester of FY 2019/2020. The data in the analysis uses statistical methods with the help of SPSS software  version 17. The results of the data analysis showed that (1) there was a positive and significant relationship of learning motivation to student learning outcomes with a correlation coefficient of 0.531, thus contributing 28.20%. (2) Then, there is a positive and significant relationship between the attitude of learning towards student learning outcomes with a correlation coefficient of 0.559, thus contributing 31.25%. (3) Furthermore, there is a positive and significant relationship between learning motivation and learning attitudes together with student learning outcomes with a correlation coefficient of 0.657 thus contributing 43.16%. This proves that learning motivation and learning attitudes contribute strongly in improving student learning outcomes in the Digital Simulation course of PTIK FKIP UBH study program in Padang City.","PeriodicalId":43182,"journal":{"name":"Estudios Demograficos y Urbanos","volume":"4 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2021-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42619772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because the position of the speaker as the main characters is themselves of their own knowledge. The proximal form is more dominant rather than the distal form in the place deixis. In the time deixis was used by present time, past time, and future time. In the social deixis was used in two parts. Therefore, absolute social deixis and relational social deixis. After that in the discourse deixis used through discourse marker and form of demonstrative this/that. Also, deixis is highly context-dependent that is cannot be understood without considering the context. Therefore, in realizing students' speech texts, English learners cannot only understand in the whole context of the students' speech text also trust on their vocabularies need. Because of this research for the future can improve knowledge of pragmatics especially in the speech text of deixis.","PeriodicalId":43182,"journal":{"name":"Estudios Demograficos y Urbanos","volume":"4 1","pages":"428-437"},"PeriodicalIF":0.4,"publicationDate":"2021-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49553698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the important role of reading comprehension, many researchers indicate that the students’ reading comprehension skill is not satisfactory yet. This situation is also found in MAN 3 Malang. The students were found to have difficulty in comprehending the reading text because of low ability in reading, especially in drawing on their prior knowledge. Thus, the researcher implemented the Making Connection Technique in the reading lessons in collaboration with the classroom teacher. This technique has several steps; they are text to text, text to self, and text to world. The design of this research was Classroom Action Research covering four stages; they were planning, implementing, observing, and reflecting. The subjects of the study were 29 students of class XI SCIENCE 1 of MAN 3 Malang. The instruments used to collect the data were students’ reading comprehension pre and post-test), observation checklist, and field notes. Since the researcher aimed to know whether the technique helped the students in both the lower and upper groups, this research is successful if there was a significant improvement from their pre and post-test scores. The findings of this study revealed that by using the Making Connection technique, the student's reading comprehension scores had achieved the criteria of success. The students also showed a positive attitude during the implementation of the technique. The several procedures of using the technique found are (1) making text to text-connection in the group, (2) making text to self-connection in the group, (3) making text to world-connection in the group, and (4) having a class discussion related to the results of their discussion.
