Stress is generally defined as a state where someone is mentally disturbed as the response to the adversity that he/she experiences. Junior High School students usually are not aware of the stress that they encounter. This research aims to compare two classification methods of KNN and Naïve Bayes to determine stress level. The data of this research were gathered from 254 respondents from Catholic Junior High School of Don Bosco Bitung. The tests of k-cross validation and percentage split from the data showed that Naïve Bayes method excelled KNN method. With k=3, KNN accuracy reached 86.61% at the highest and Naïve Bayes reached 87.40%. Meanwhile, based on percentage split test, the average of Naïve Bayes accuracy was higher than KNN with percentage of 88.31%. Moreover, for the precision and recall, Naïve Bayes was higher than KNN with 88.30% and 87.40% seen from the k-cross validation.

The Government through 2013 curriculum wants to prepare students who are ready earlier than expected to develop his talents, so that the government create a system of specialization of class X with a variety of considerations which is considered very mature, with a value based on the level of the previous studies, the value of the psychological test, the data of interest, and value specialization. It is necessary to study to classify the high school students specialization 2013 curriculum, 2013. In this study, algorithm that used is Naive Bayes. Probability Bayes principle or principles is the principle that is based on the observation and focused on the use of traditional methods. Classification of Naive Bayes assumption that holds the relationship between independent features or attributes that make it more effective for the categorization, a simple, fast and produces a high degree of accuracy. The step of research include data collection and testing of Naive Bayes algorithm. In this study, the dataset used is desirable student Department, the Department of the Results of Psychotest, average value of Mathematics of the students when they were in the first to the fifth semester of junior high school, Math test scores, the average value of IPA of the student when they were in the first to the fifth semester of junior high school, IPA test scores, the average value of IPS of the student when they were in the first to the fifth semester of junior high school and IPS test scores. This study aims to determine the Clasification Results using Naive Bayes Method of determining the appropriate students’ specialization on 2013 curriculum, based on data value of SMAN 2 Banjarmasin. The significance of this study can be used by the school to perform accurate algorithm as a tool to calssify the corresponding specialization in 2013 curriculum and to provide an overview and understanding of Naive Bayes prediction methods, as a case study of the value of all the students of SMAN 2 Banjarmasin andto determine their specialization and it is also expected to become a tool determines the appropriate specialization curriculum in 2013 for students of SMAN 2 Banjarmasin. The result of the try out by using Naïve Bayes method to assess high school students’ specialization reached the assessment result that has the highest accuration level 99.47% and AUC value 1.000.

ABSTRACT This paper attempts to analyze the test items in the English National Final Examination (UAN) for Junior High School Students in the academic year 2009/2010. This study aims at analyzing the compatibility of the test items of package A in reading and writing section of English National Final Examination for Junior High School Students with the standard of graduate competence and the cognitive domains used in the test. The data were collected by using documentary method, while in analyzing the data the writers focused on matching the compatibility of the test items with the Standard of Graduate Competence and identifying the cognitive domain used. From the analysis, it was found that the test items of package A in reading and writing section of English National Final Examination 2009/2010 were in line with the Standard of Graduate Competence (SKL) arranged by the government. The cognitive domains in reading section mostly used level of comprehension. The cognitive domains in writing section used the application and the synthesis level. ?é?á Key words: analysis, test items, national final examination

In this paper I explore the connection between a/r/tography and poetic inquiry, and how together they cultivate multiple ways of understanding. I further claim that classroom situations are most provocative of thoughtfulness and critical consciousness when each student participates in the classroom conversation from his or her lived situations. While difficult, teachers who can facilitate rich interchanges of dialogue within a plurality of voices are genuinely creating communities of difference and thus imagining real possibilities for social change.
