Abstract

This study is a quasi-experimental research (Quasi Experiment) that aims to determine the effect of guided inquiry learning model to the problem-solving ability of students Class XI SMAN 11 Makassar. The study design used was "posttest-Only Control Group Design ".The study population was the students of class XI MIA SMA Negeri 11 Makassar consisting of six classes, while the sample is a class XI MIA 4 as an experimental class and class XI MIA 6 as the control class with the number of students each 34 people. The experimental class was studied by guided inquiry model. While the control class was with conventional learning models.The independent variable in this study was guided inquirí learning model and conventional learning model. The dependent variable is the ability to solving problem.Data retrieval problem solving skills performed by administering the test problem solving abilities. Problem-solving abilities data were analyzed using descriptive statistics and inferential statistics. The results of inferential statistical analysis of the data prerequisite troubleshooting capabilities indicate that the data on the class experimental and control classes were not normally distributed, but had a homogeneous variance. Hypothesis testing was done by using a non-parametric test of Mann-Whitney test with α = 0.05 was obtained Zcalculated> Ztable (2:02> 1.64). The effect of guided inquiry learning model to the problem-solving ability of students in class XI MIA SMAN 11 Makassar studies on the subject matter of the reaction rate.

Abstract

This research aims to determine the effect of the snowball throwing method on the discovery learning model of students learning outcomes in the subject matter of the Periodic System of Elements. The Research Population of all students in X MIA MAN 1 SIDRAP, period 2018/2019. The sample of 29 people in class X MIA 2 as an experimental group was taught by the snowball throwing method in the discovery learning model and 29 people in class X MIA 1 as a group control that was learned by the discovery learning model without the snowball throwing method. Data collection through student learning outcomes and questionnaire responses to research design posttest control group design. The results of the descriptive analysis showed that the average value of the experimental group using the snowball throwing method on the discovery learning model, it was higher at 73.05 compared to the control group which only used the discovery learning model without the snowball throwing method which was 69.74. The results of hypothesis testing on inferential statistics using the Mannwhitney test obtained a Zhitung value of 3.62 and at the confidence level (α) of 0.05 obtained Ztable 1.65. Therefore, Zhitung> Ztable then H0 is rejected and H1 is accepted, it shows that there is a significant effect of using the snowball throwing method on the discovery learning model on the learning outcomes of class X MIA MAN 1 SIDRAP in the subject matter of the periodic system element.

Abstract

Penelitian ini adalah penelitian Eksperimen Semu yang bertujuan untuk mengetahui pengaruh integarasi metode diskusi Toulmin argumentation pada model pembelajaran Learning cycle 5E terhadap keterampilan berpikir kritis peserta didik. Desain penelitian adalah “Pretest Posttest Control Design”. Variabel bebas adalah integrasi Toulmin argumentation pada model pembelajaran Learning cycle 5E dan model pembelajaran Learning cycle 5E, dan variabel terikat adalah keterampilan berpikir kritis. Populasi adalah seluruh kelas VIII SMP Negeri 8 Makassar yang bukan kelas akselerasi yang berjumlah 6 kelas. Pengambilan sampel dilakukan dengan menggunakan teknik purpossive random sampling. Sampel penelitian ada dua kelas yaitu kelas VIII A sebagai kelas eksperimen dan kelas VIII E sebagai kelas kontrol dengan jumlah peserta didik masing-masing 33 orang. Instrumen penelitian berupa tes keterampilan berpikir kritis. Data keterampilan berpikir kritis yang diperoleh dianalisis dengan menggunakan statistik deskriptif dan inferensial. Hasil analisis menunjukkan nilai rata-rata pretest dan posttest berturut-turut pada kelas eksperimen adalah 23,48 dan 73,95 dengan rata-rata N-gain 0,655 (sedang). Sedangkan kelas kontrol 21,23 dan 59,85 dengan rata-rata N-Gain 0,507 (Sedang). Ketuntasan pada kelas eksperimen sebesar 39,39% sedangkan pada kelas kontrol sebesar 0% dengan nilai KKM adalah 79. Hasil pengujian hipotesis menggunakan uji-t diperoleh nilai thitung = 5,6212 dan pada taraf signifikan α = 0,05 dengan dk = 64 diperoleh ttabel = 2,0369. Oleh karana thitung > ttabel, maka H1 diterima dan H0 ditolak. Hal ini dapat disimpulkan bahwa integrasi metode Toulmin argumentation pada model pembelajaran Learning cycle 5E berpengaruh positif terhadap keterampilan berpikir kritis peserta didik kelas VIII SMP Negeri 8 Makassar pada materi pokok zat aditif, zat adiktif, dan psikotropika.
