Communication skills need to be improved during learning. However, the learning process in schools has not fully implemented learning models that can improve students' communication skills. Learning in schools is still teacher-centered, lack of use of Information Technology (IT), students’ inactivity, and their lack of interest in learning in class. The solution is to apply the PBL learning model in IT interventions. The research objective was to develop students' communication skills. The instrument used is was a rubric to assess communication that had been validated by experts. The research design was Randomized Control Group Posttest Only Design. This type of research is a quasi-experimental. The data were analyzed by using  the two-way ANOVA test. The results showed that there was a significant difference between the PBL learning model and the information technology intervention on the communication skills of students with an average score of 64.27% in the experimental class and 57.70% in the control class and a significant value of 0.00

Abstrak. Keterampilan komunikasi perlu dikembangkan dalam proses pembelajran. Namun, proses pembelajaran di sekolah belum menerapkan model pembelajaran yang mengembangkan keterampilan komunikasi peserta didik. Pembelajaran di sekolah masih dominan berpusat pada guru, masih kurang pemanfaatan Teknologi Informasi (TI), tidak aktif, dan kurang minat belajar dikelas. Untuk mengatasi masalah yang dikemukakan tersebut adalah menerapkan model pembelajaran Problem Based Learning(PBL) yang diintervensi TI. Penelitian ini bertujuan untuk meningkatkan keterampilan komunikasi peserta didik. Instrumen yang digunakan berupa rubrik untuk menilai komunikasi yang telah divalidasi oleh pakar. Analisis data yang digunakan yaitu uji Anova dua arah. Hasil penelitian ini menunjukkan perbedaan yang signifikan antara model pembelajaran PBL yang diintervensi teknologi informasi terhadap keterampilan komunikasi peserta didik dengan nilai rata-rata kelas eksperimen 64,27 persen dan kelas kontrol 57,70 persen.Abstract. Communication skills need to be developed in the learning process. However, the learning process in schools has not yet fully implemented a learning model that develops students' communication skills. Learning in schools is still dominantly teacher-centered, there is still a lack of use of Information Technology (IT), not active, and lack of interest in learning in class. To overcome the problems raised by applying the Problem Based Learning (PBL) learning model with IT intervention. This study aims to improve the communication skills of students. The instrument used is a rubric to assess communication that has been validated by experts. Analysis of the data used is a two-way ANOVA test. The results of this study indicate that the communication skills of students in the experimental class (64.27 percent) are significantly higher than the control class (57.70 percent). It can be concluded that problem-based learning that is intervened by information technology has a positive effect on students' communication skills.

Students' creative thinking skills need to be developed in the learning process. However, the learning process in schools has not fully implemented learning models that develop students' skills. From the results of observations at SMAN 7 Padang, learning at school still does not make use of Information and Communication Technology (ICT) and lacks interest in learning in class. To overcome these problems, the Problem Based Learning (PBL) model which is intervened with the use of ICT is applied. The use of ICT used is utilizing cellphone and internet networks in obtaining broader information. This study aims to analyze the effect of the implementation of the problem-based learning model that is intervened by information technology on students' creative thinking skills. This type of research is quasi-experimental research with a randomized control-group posttest only design. The results of testing the hypothesis, namely tcount > ttable, indicate that the research hypothesis is accepted.

This research based on the problem on SMAN 1 Lubuk Alung, those are inappropriate learning model choices and low of students’ learning competencies. An efforts could done to solve it was implementation of problem based learning model charged with science literacy toward the students’ learning competencies on the topic of excretion system at XI grade of SMAN 1 Lubuk Alung. This research aimed to know the effects of Problem Based Learning (PBL) charged with science literacy toward the students’ learning competencies at XI grade of SMAN 1 Lubuk Alung. The type of this research was experimental research and designed on Control Group Posttest Only. The populations of this research were all of the students at grade XI MIPA of SMAN 1 Lubuk Alung academic years 2017/2018 that consisted of seven classes. This research used purposive sampling technique to take the samples; those are XI MIPA 3 as experiment group and XI MIPA 2 as control group. The research’s instruments used were test for cognitive competence and observation sheets for affective and psychomotor competence. Hypothesis was tested by using T-test method.Based on the thesis result by using t-test, it can be concluded that on students’ cognitive competence   tscore 4,15> table 1,67, on students’ affective competence tscore  5,07 > table 1,67, and on students’ psychomotor competence tscore 1,69 > table 1,67. It showed that hypothesis was accepted. So it can be concluded that the implementation of Problem Based Learning (PBL) charged science literacy model improved toward students’ learning competences at XI grade of SMAN 1 Lubuk Alung significantly with 0,05 degrees of truthiness.
