Using Macromedia Flash- Assisted PBL and PjBL Learning Model to Improve Acid Base Leraning Outcomes

Anna Juniar, Mayloretta Barus

Abstract


Abstract Learning science provides a challenge for students who have lost interest in learning science, especially chemistry lessons. Resulting in low student learning outcomes, because apart from being abstract in nature, it is influenced by the positive attitudes of students and teacher readiness in managing innovative learning so that the skills that students must have are lacking in dealing with the advancement of 21st century education. The purpose of this study was to determine differences in learning outcomes (cognitive, affective and psychomotor aspects) using the PBL and PjBL learning models in Acid-Base material assisted by macromedia flash which was implemented at SMA Negeri 1 Delitua.Technique The selection of the sample used was purposive sampling with the research design Two Group Pretest – Posttest Design. Data collection techniques used tests for cognitive learning achievement and non tests for affective and psychomotor achievements. Data analysis used the normality test with the Chi Square test, homogeneity through the F-test and two-party hypothesis testing to analyze whether or not there was a difference between the two experimental classes. The results showed that there were differences in cognitive and psychomotor learning outcomes and there were no differences in students' affective aspects between PBL and PjBL models assisted by macromedia flash.

Abstrak Pembelajaran sains memberikan tantangan bagi siswa yang kehilangan minat belajar sains terkhusus pelajaran kimia. Mengakibatkan rendahnya hasil belajar peserta didik, karena selain kimia bersifat abstrak, dipengaruhi sikap positif siswa dan kesiapan guru dalam mengelola pembelajaran inovatif sehingga keterampilan yang harus dimiliki peserta didik kurang dalam menghadapi kemajuan pendidikan abad ke-21. Tujuan penelitian ini untuk mengetahui perbedaan hasil belajar (Aspek kognitif, afektif dan psikomotorik) menggunakan model pembelajaran PBL dan PjBL pada materi Asam Basa berbantuan Macromedia Flash yang diimplementasikan di SMA Negeri 1 Delitua. Teknik pemilihan sampel yang digunakan adalah Purposive Sampling dengan desain penelitian Two-Group Pretest- Posttets Design. Teknik pengumpulan data menggunakan tes untuk prestasi belajar kognitif dan non tes untuk prestasi afektif dan psikomotorik. Analisis data menggunakan uji normalitas dengan uji Chi Square, homogenitas melalui uji-F dan uji hipotesis dua pihak untuk menganalisis ada atau tidaknya perbedaan antara dua kelas eksperimen. Hasil penelitian menunjukkan adanya perbedaan hasil belajar kognitif dan psikomotorik dan tidak ada perbedaan hasil belajar afektif antara model PBL dan PjBL berbantuan Macromedia Flash.
