Two mathematical mindsets are two of four mathematical midsets what integrated in the technique of writing observational report text. The four mathematical mindset is the one of latest writing technique that was invented by Ayu Utami. This research aims to determine whether or not the influence of two mathematical mindset assisted skill of writing text on observational reports at 4th grade of SDN Dukuh Menanggal 1 Surabaya. Research use quantitative approach with experimental research is quasi experimental posttest-only design. Sampel in this research is student at 4thA grade as control team and 4thB grade as experiment team.T-test shows that the value of t-test count obtained is 9,860, while the t-table value at 5% significance level with degrees of freedom 37 obtained for 2,0262. This indicates that t-test count (10,794) > t-table (2,0262), so that the hypothesis accepted. The conclusion of research is two mathematical mindsets’ technique is influence assisted by skill of writing text on observational reports at 4th grade of SDN Dukuh Menanggal 1 Surabaya.

This study aimed to describe the effect of PQ4R learning methods with internet-assisted on students’ learning outcomes of class XI SMA Labschool UNTAD Palu on salt hydrolysis material. The type of research was quasi-experimental with a nonrandomized pretest-posttest control group design. This study was conducted with two groups, namely the XI IPA class 1 as the experimental group (n = 21) and the XI IPA class 3 as a control group (n = 23). The testing of the research data used a two-party t-test statistical analysis. The results of data analysis obtained that the average of an experimental class was 63.19 with a standard deviation of 7.37 and a control class was 57.22 with a standard deviation of 8.19. The results of testing the hypothesis with the two-party t-test statistics obtained -ttable<tcount> +ttable (tcount 2.54 and ttable 1.68) with a significance level (α) = 0.05 and degrees of freedom (dk) = 35. Based on the results testing of the hypothesis, it can be concluded that H0 was rejected and H1 was accepted. This means that the PQ4R learning method with internet-assisted has a positive effect on the learning outcomes of students class XI SMA Labschool UNTAD Palu.

This research is entitled “Using graphic organizer strategy in teaching writing on narrative paragraph (experimental research). Writing is a very important subject that should be learned by English learners. The students should be able to express their ideas and opinion either in the form of a sentence or paragraph. However, the researcher found that many students at the Second Grade Students of SMP Negeri 1 Tanah Luas could not express their ideas and develop into the paragraph. Hence, the appropriate strategy of teaching and learning is very important to help students master writing skills. This research aims to know the effect of achievement between the students who are taught writing by using graphic organizers from those taught writing in the narrative by using traditional methods. This research was experimental research and used a quasi-experimental design. The samples chosen in this research were the whole students of class VIII2 and VIII4 of SMPN 1 Tanah Luas. Class VIII2 consisted of 25 students was chosen as experimental group and class VIII4 consisted of 24 students was chosen as control group. This research was conducted in three phrases; there were pre-test, treatments and post-test. The data collection technique used in this research was test. The tests were pre-test and post-test. The researcher gave pre-test before giving treatment and post-test after giving treatment. The treatment was conducted in three meetings. The data was analyzed by using t-test formula. The research result and the hypothesis authentication found by using t-test formula in significant level 5% or α = 0.05 were obtained that ttest > ttable. The ttest found in this research was 3.91. Meanwhile, ttable was gotten from the list of distribution value with degree of freedom = 47, because the data not in the table, the researcher used interpolation approach and obtained = 1.67. So >  = 3.91 > 1.67. It meant that Ha was accepted and Ho was rejected. So, graphic organizer strategy significantly affects the students’ ability in mastering writing.   Kata Kunci: graphic organizer strategy, teaching and learning, writing narrative paragraph

The Subject

The problem that we need to be solved in the world of our education is the weak learning process. The learning process in the classroom is still directed at the child's ability to memorize information. While biology requires logical and reasonable learning to be accepted and absorbed by the brain so that it can last long. The aim of the research is to know the influence of course review horay learning toward student’s of cognitive learning class ten in the subject matter cell in MA Sabilul Hasanah Kecamatan Sembawa Kabupaten Banyuasin. This research method used quasi-experimental design with a quantitative approach research pretest-posttest control group design. The sample is taken by using purposive sampling techniques. The sample was grade XI MIA 2 as an experimental class and class XI MIA 1 as the control class. The instrument used in this research is a test to measure student’s cognitive learning about the cognitive categories C1-C4. Data analysis use the t-test, data on the calculation difference average posttest both groups earned value t-test much as 4,806 while value t-table with significant level5% with degrees of freedom (dk) 42 is equal to1,684, it can be said that t-test > t-table means the alternative hypothesis (Ha) be accepted and the null hypothesis (H0) rejected.
