Vocational Higher Education is a formal college providing knowledge as well as preparing the students for six months apprenticeship after five semesters of school. This study is based upon work that the researcher has done to investigate the contribution of this institution especially insurance administration and actuary seen from the student’s perspectives for apprenticeship to develop their skills. This study used qualitative data which were collected by interviewing the randomly chosen apprentices and are measured with the questionnaire. The study shows that 58,5% of total apprentices had difficulty when they are doing their job which is caused by what they had to do is a little bit different from the theory taught in college. But they think the lecturers had an important role in learning and gave them many theories before they went to the apprenticeship. The finding revealed that they preferred to learn by watching others working. They watched, learned, and did the job.

This study aims to identify students’ errors in solving problem equals to PISA’s based on Newman procedures. Qualitative-descriptive research was used in conducting this study and the subjects were third-grade students at SMP Unggul Sigli in year 2017/2018. Data was collected using tests and interviews. The instrument of this study was a sheet consisting of 5 (five) mathematical questions that composed equivalent to PISA’s problem. Analyzing students’ errors was guided by analyzing procedures developed by Newman which contain 5 (five) kinds of error, they are (1) reading error; (2) understanding error; (3) transformation error; (4) processing skill error; and (5) writing error. The result showed the percentage of each kind of errors made by students which detailed as follows, reading error comprised 37,1% of students; error in problem understanding made up 47%; 73% of subjects made error in transforming; 80% of students had error in processing; and error in writing final answer made up 78,1% of them. By analyzing the percentage, it is identified that the three most common mistakes are processing error, transformation error, and error in writing a final answer.

The steps consist of the problem and need analysis, literature review, product design, validity, practitioner trials. The research subjects in this development were two validators consisting of material expert validators, instrument design expert test validators, and five practitioners. The type of data taken in this study is qualitative data. The instrument used in the study was an open questionnaire. The process stages in developing are (a) Analysis of problems and needs, (b) literature review, (c) product design, (d) validity, (e) trial practitioners. The product specifications developed in the module are that there are three chapters on introduction, concepts, and procedures accompanied by examples by using types of problem-solving, namely problem-solving design and story problem. Teacher's perception in the teacher guidance module is positive, of the five practitioners recommending that it be used as a guide in making problem-solving problems.","PeriodicalId":34056,"journal":{"name":"Edumatika","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82505226","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}
