Development of Student E-Worksheet Based on PBL (Problem Based Learning) to Pratice Metacognitive Abilities of High School Student on Reaction Rate Material

Perkembangan pada abad 21 yang begitu pesat mengharuskan inovasi diberbagai bidang salah satunya ialah Pendidikan. Metakognitif sebagi salah satu kemampuan yang dibutuh. Melalui implementasi kurikulum 2013, kemampuan metakognitif  yang dibutuhkan pada abad 21 ini dilatih. Model pembelajaran Problem Based Learning (PBL) dapat mendukung peserta didik untuk mengembangkan pengetahuan serta kemampuan metakognitifnya. Tujuan dari penelitian ini ialah untuk mengembangkan E-LKPD berbasis Problem Based Learning untuk melatihkan kemampuan metakognitif peserta didik. Model pengembangan E-LKPD dalam penelitian ini menggunakan model 4D. Pengembangan Student E-Worksheet dinyatakan layak untuk melatih kemampuan metakognitif siswa. Hasil validitas isi 94,81% dan validitas konstruk 96,97%. Kemudian E-LKPD dinyatakan praktis dengan hasil observasi aktivitas peserta didik sebesar serta hasil angket respon dengan nilai sebesar 96,37%. Keefektifan E-LKPD dilihat dari nilai pretest dan postest yang dianalisis menggunakan SPSS uji Paired Sample t-Test didapatkan nilai signifikasi 0,000 yang berarti E-LKPD yang dikembangkan efektif.

Developments in the 21st century is so rapid that innovation in various fields is required one of which is education. Through the implementation of the 2013 curriculum, the metacognitive abilities needed in the 21st century were train. The Problem Based Learning (PBL) model can support students to develop their metacognitive abilities. The rate of reaction as one of the subjects that are difficult to understand can be taught through the PBL learning model. The aim of this study is to develop a Student E-Worksheet based on Problem Based Learning to train students metacognitive abilities on reaction rate material. The Student E-Worksheet development model in this study uses a 4D model. The development of Student E-Worksheet was declared feasible to train student metacognitive abilities. The results of content validity of 94.81% and construct validity of 96.97%. Then the results of practical of observing student activities and questionnaire with a value of 96.37%. The effectiveness of the Student E-Worksheet is seen from the pretest and posttest values ​​which were analyzed using the SPSS Paired Sample t-Test test, a significance value of 0.000 was obtained.
