The aim of this research was to determine the significant difference in the application of quantum teaching learning model in natural science subject. This research was conducted on fourth grade students of SD INPRES Kupa-Kupa with the population of 20 students. The sample of this research divided into control group consisted of 10 students and the experimental group consisted of 10 students. This research used a post-test only design. Data analysis used normality, homogeneity and hypothesis test. The result showed that the average score obtained by post test of experimental group, it was 87 higher than control group, it was 52. The t-count = 14.42 > t-table = 2.228, it could be concluded that H0 was rejected and 𝐻𝑎 was accepted or the application of a quantum teaching learning model could improve the learning outcomes on fourth grade elementary students

Kurangnya penggunaan model pembelajarn yang inovatif dan kreatif. Berpengaruh terhadap rendahnya hasil belajar siswa. Penelitian ini bertujuan untuk menganalisis dampak dari penggunaan model pembelajaran Discovery Learning pada hasil belajar mata pelajaran IPA siswa kelas V SD. Metode dalam penelitian ini yaitu metode pre-experiment tanpa adanya kelompok pembanding. Penelitian ini mengunakan One Group Pretest-Posttest Design. Populasi penelitian ini adalah 16 orang siswa. Teknik pengumpulan data yang digunakan adalah Persiapan Penelitian, Pelaksanaan Penelitian, Memberikan Pre-test dan post test, Mengumpulkan Data dan Analisis Data.  Teknik analisis data menggunakan  t-test dan data satistik yaitu Modus (Mo), Median (Md), Mean (Me). Hasil penelitian menunjukkan penerapan model pembelajaran Discovery Learning dapat meningkatkan hasil belajar IPA kelas V SD dengan perbedaan rata-rata diperoleh nilai posttest = 77 lebih tinggi dibandingkan nilai pretest = 33, sedangkan thitung = 14.42 > ttabel = 2.228. Maka dapat disimpulkan H0 ditolak dan Ha diterima. Dapat disimpulkan bahwa terdapat perbedaan yang signifikan hasil belajar IPA antara kelompok siswa yang dibelajarkan melalui model Discovery Learning dan kelompok siswa yang dibelajarkan melalui pembelajaran konvensional. Dengan  demikian, dapat disimpulkan bahwa penggunaan model Discovery berpengaruh terhadap hasil belajar IPA siswa kelas V SD.

Tujuan dari penelitian ini adalah untuk mengetahui Penerapan Media Permainan Congklak dalam Meningkatkan Kemampuan Berhitung Siswa Kelas II SD Inpres Wosia. Metode dalam penelitian ini yaitu metode pre-experiment tanpa adanya kelompok pembanding. Penelitian ini mengunakan One Group Pretest-Posttest Design dengan teknik analisis data menggunakan paired t test. Teknik  pengumpulan data yang digunakan adalah soal tes. Penelitian ini menggunakan keseluruhan populasi yang berjumlah 24 orang siswa. Hasil penelitian menunjukkan perbedaan rata-rata diperoleh nilai posttest = 77.91 lebih tinggi dibandingkan nilai pretest = 43.75, sedangkan thitung = -14.697 ≠ ttabel = 1.714 .  Maka dapat disimpulkan H0 ditolak dan Ha diterima atau penerapan media permainan Congklak dapat meningkatkan kemampuan berhitung siswa Kelas II SD Inpres Wosia.

This study aims to examine the error of speaking the language of the North Halmahera speech at the fonological level in the interaction of learning and the factors behind it. The type of research used is qualitatively descriptive with phenomenological approaches. Data is obtained using simak method with basic tapping technique. Once the data is obtained, it is then analyzed using the agih method and the padan method at the time of the speech interaction. Based on the results of the analysis, it was found that language errors include, errors in pronunciation and spelling. The error in the tester consists of  the error using phoneme /e/ (pepet) pronounced to /é/ (taling) caused by the language of the mother not knowing the phoneme /e/ (pepet), pronouncing phoneme /i/ to /é/ (taling), phoneme /e/ being /a/, phoneme /ai/ being /e/, phoneme / é/ (taling) becomes /i/, phoneme diftong /au/ becomes /o/, phoneme /c/ becomes /sé/, phoneme /v/ becomes /p/, phoneme /u/ becomes /w/, phoneme /n/ becomes /ng/, phoneme /i/ manjadi /e/, phoneme /kh/ becomes /h/, phoneme /z/ becomes /s/, phoneme /z/ becomes /j/, phoneme /sy/ becomes /s/, phoneme /f/ becomes /p/, phoneme /h/ at the end of a specific word, phoneme /o/ becomes phoneme /u/, Phoneme removal /h/ in a specific word, and Phoneme removal /k/ in a specific word. Spelling errors consist of capital letters usage, use of punctuation, and use of words. Thus it can be inferred language errors in the phonological state including pronunciation and spelling errors.

The students really need nutritional intake therefore breakfast is very important for them. Children who are accustomed to breakfast will have better abilities than children who are not accustomed to breakfast. Breakfast will stimulate growth and maximize children's abilities at school. This study aims to analyze the correlation of breakfast with the learning concentration of fourth grade elementary school students. The method used in this research is a survey method by conducting treatments in data collection, by distributing questionnaires, tests, structured interviews, and so on. This study uses a descriptive approach. The subjects in this study were 24 students including 11 male students and 13 female students. While the research stages are: 1) Documentation; 2) Questionnaire (Questionnaire preparation, Questionnaire Validity Test, Questionnaire Reliability Test. The instrument or measuring instrument used is the Likert Scale and the data analysis technique used is using "significant test" the correlation test can analyze how the relationship between x and y variables. To calculate item analysis and correlation, the product moment correlation coefficient formula is used. The results of the research show that the correlation between Breakfast and Learning Concentration results in the number 0.987 where the resulting number is positive. This shows that there is a very close relationship between Breakfast and Student Learning Concentration. Based on the results of the correlation analysis, the hypothesis proposed is that there is a relationship between breakfast and student concentration. It means that there is a very significant relationship between breakfast and the learning concentration of fourth grade elementary school students.
