This study aimed to analyze the effect of the application of the Think-pairs-Share and Means- Ends Analysis learning Achievement of a student on reduction-oxidation in class X at SMAN 7 Palu. This study was a ween experiment with a static group pretest-posttest design. This study was carried out by holding two groups of class X Science 1 as the experimental one group (n = 25) and class X science 2 as the experimental two groups (n = 28). Results of the data analysis showed the average value (X2) of the experimental one class was 68.56 with a standard deviation of 16.97 dan (X2) of the experimental two class was 56.14 with a standard deviation of 13.12. Based on the hypothesis test results with t-test statistical of two parties obtained –ttable ≤ tcount ≥ + ttable (tcount = 1.89 and ttable = 1.67) with a significance level of α= 0.05 and degrees of freedom of 51, then Ho was rejected and Ha was accepted. It can be concluded that there was an effect of the application of the think-pairs–share and means-ends analysis learning model toward learning achievement of students in class X at SMAN 7 Palu on reduction-oxidation.

This study aimed to determine the differences between students’ learning outcomes using guided inquiry-type learning model and team assisted individualization (TAI)-type learning model on redox reaction concept in grade X at SMA Negeri 2 Sigi. This study was a quasi-experiment method. The sample was class X MIA5 as an experiment class I (n = 24 students), and class X MIA1 (n = 24 students) as an experiment class II. The data analysis showed that the average score of experiment class I was 73.79, and the experimental class II was 71.45. The results of the hypothesis test with t-test two-party statistics obtained tcount = 0.86. The value was in the reception area of H0 that was between -1.68 and 1.68. The result from the statistical test showed that there was no difference between the students' learning outcomes using guided inquiry-type and team assisted individualization type learning models on redox reaction concept material in grade X at SMA Negeri 2 Sigi

This research aims to determine calcium level (Ca) and iron (Fe) on red and green spinaches at Parigi Moutong. The method used in this research is spectrodirect method. The research result shows that the calcium level (Ca) and iron (Fe) on green spinach was 0.97 mg/kg and red spinach was 58.33 mg/kg at Pelawa village, while the calcium level (Ca) and iron (Fe) on green spinach was 0.62 mg/kg and red spinach was 50.39 mg/kg. From the research results obtained, it can be seen that the level of calcium and iron on red and green spinach in where the red spinach levels higher than the green spinach levels.
