Urban open data is the key to the construction of smart city. Through the research on evaluation of urban open data, the concept, types, characteristics and other basic problems of urban open data are systematically summarized. From perspective of "quality", "opening" and "acquisition", a complete urban open data evaluation framework and index system is built. And the corresponding weights of evaluation indexes and score and overall rating methods are determined, so as to objectively evaluate the conditions of urban open data, and describe, monitor, guide and promote the construction and development of urban open data.
The present study aimed to investigate Vocabulary Learning Strategies (VLSs) used by undergraduate students (S1) of 6th semester and how they learned or acquired VLSs. In addition, the study compares the use of VLSs between low and high achievers of undergraduate students that consisted of 30 students. An explanatory sequential mixed research method was implemented in this study. The corroboration was used employing a questionnaire adapted from Schmitt’s taxonomy (Classification of VLSs) as the instruments. As for the qualitative approach, the writer conducted interviews to explore how the students acquired VLSs. The research report showed that the mean score indicated the uses of Determination strategies are most frequently used by both of achiever. Likewise, the least frequently used vocabulary learning strategy was Social strategies (Consolidation). There were no great differences found in using vocabulary learning strategies between the low and high achievers and they learn the most frequently used strategy in several situations such as, course, organization, English club, media, and etcetera. Effective vocabulary learning and teaching strategies need to be incorporated into students’ vocabulary learning process.
In this article, we use set, function, sieve and number theory to study the prime and composite numbers, prove that the lower limit formula of the number of prime numbers derived from the Euler's function, and find d(n) to count the lower limit formula of the number of prime integer-pairs. We proved that Goldbach's conjecture is correct by mathematical induction. Finally, we proved proof reliance by mathematical analysis and computer data.
ABSTRACT Norzulya Aries,2020.Teaching Vocabulary Through Students’ Visual Spatial Intelligence at The Second year of MAN SidenrengRappang( Supervised by Hj. Nanning and Mujahidah). This research was aimed to investigate the teaching vocabulary through students’ visual spatial intelligence at the second year of MAN SidenrengRappang. The purpose of this research was to know is teaching vocabulary through students’ visual spatial intelligence able to enhance students’ vocabulary and are students interested in learning vocabulary through students’ visual spatial intelligence. This research took the second year focus on IX Mia 3 with 27 students as sample of MAN SidenrengRappang. This research was classified as quantitative research, where the instrument this research were test consist pre-test and post-test and questionnaire. The sampling technique of this research was random group sampling. In this research used pre-experimental design with one group pre-test and post-test The researcher found that: 1) teaching vocabulary through students’ visual spatial intelligence able to enhance students’ vocabulary. The students mean score of post-test more higher than pre-test, where the mean score of pre test 77,48 while the mean score of post test 83,70. Then the result of t-test was 3,76 was higher than value of t-table 1,706 and for the level significant 5% or 0.05 and degree of freedom (df) =26. Thus, the researcher concluded that teaching vocabulary through students’ visual spatial intelligence able to enhance students’ vocabulary. Furthermore, the nullhypothesis is rejected and the alternative hypothesis is accepted. 2) the students’ interested through the questionnaire also had concluded and most of them got 81-100 score with percentage was 83,76%. Based on the liker scale the student is very interested in learning vocabulary through students’ visual spatial intelligence. in concluded that teaching vocabulary thriugh students’ visual spatial intelligence able to enhance students’ vocabulary.
Intensive speaking is drills or repetitions focusing on specific phonological or grammatical points, such as minimal pairs or repetition of a series of imperative sentences, where learners are going over to practice some phonological or grammatical aspect of language. Cooperative script learning model is a learning where students work in pairs and take turns verbally summarizing the parts of the material being studied.The purpose of this research was to know the difference students’ intensive speaking skill before and after using cooperative script learning model atSMK DDI Parepare.The samples of this research were 23 students from XI TKJ (Teknik Komputer dan Jaringan) class and XI PMR (Bisnis Daring danPemasaran) class. The researcher used cluster sampling technique to decide the sample.The researcher used pre-experimental design in one group was given pre-test, treatment and post-test design.To collect the data, the researcher used tests that are pre-test and post-test. The researcher also gave observation.The result in this research was indicated that there was the improvement of the students’ intensive speaking skill. It was indicated by the students’ mean score of post-test (7) was greater than pre-test (5.5). Even, for the level significant (p) 5 % and df = 21, and the value of table is 1.721, while the value of t-test is 12.5. It means that the t-test value is greater than t-table (12.5 1.721). Thus, it can be concluded that the students’ intensive speaking skill is significant better after getting the treatment. So, the null hypothesis (H0) is rejected.
