Information technology is determinant factor in creating learning environment among the 21st Century generation. This qualitative descriptive research aimed to obtain theoretical views and empirical evidences of the blended-problem based learning (PBL) application. The data were collected through non-test technique through observation. The observations were made to analyze student activities in each step of the blended-PBL. In addition, the observations were also constructed to get a view of students' off-task behaviors during learning. The results of this study indicated that Google Classroom-assisted blended-PBL was well implemented in Biology learning. The all students actively participated in searching for information related to the topics covered as well as exhibiting off-task behavior. Based on the findings in this study it can be concluded that blended-PBL can be implemented as an alternative model for learning Biology in the 21st Century.

ABSTRAKPenelitian ini dilakukan untuk menganalisis efektivitas SQ5R (Survey, Question, Read, Recite, Record, Reflect and Review) terhadap pengetahuan konseptual dan retensi siswa SMA pada pembelajaran Sistem Reproduksi Manusia. Penelitian ini menggunakan metode weak experiment dengan desain "The One Group Pre-Post and Retest" yang melibatkan 34 siswa SMA Kelas XI jurusan IPA. Pengetahuan konseptual siswa yang dijaring dengan tiga buah peta konsep melalui teknik fill in meningkat dengan N-gain pada subkonsep Sistem Reproduksi Pria, Sistem Reproduksi Wanita dan Gangguan Reproduksi Manusia berturut-turut adalah 0,4; 0,3 dan 0,5 yang termasuk kedalam kategori sedang. Retensi siswa meningkat dengan skor 96%, yang termasuk dalam kategori sangat baik. Efektivitas pembelajaran dengan SQ5R terlihat dari peningkatan hasil pre-test terhadap post-test yang dijaring menggunakan soal pilihan ganda. Nilai rata-rata sebelum pembelajaran adalah 47,5 dan setelah pembelajaran adalah 74 dengan N-gain 0,5, yang termasuk kategori sedang. Hasil penjaringan daftar cek keterlaksanaan SQ5R menunjukkan bahwa sebagian besar (90,2%) siswa sudah melaksanakan tahapan SQ5R dan keterlaksanaannya mengalami peningkatan pada setiap pertemuan. Penjaringan angket tentang respon siswa terhadap pembelajaran dengan SQ5R menunjukkan bahwa 47,1% siswa merasa senang mengikuti pembelajaran dan penerapan SQ5R dalam membaca artikel membantu mereka (94,2%) dalam memahami materi Sistem Reproduksi Manusia. Kata kunci: pengetahuan konseptual, retensi, SQ5R ABSTRACTThis study was conducted to analyze the effectiveness of SQ5R on conceptual knowledge and retention of high school students in learning the Human Reproductive System. The method was weak experiment using "one group pre-post-re test design" involving 34 senior high school students in science class XI. Student conceptual knowledge collected using fill in techniques of concept maps increased with N-gain of Male Reproductive System, Female Reproductive System and Disorders of Human Reproduction were 0,4, 0,3, and 0,5 respectively. Research also found that retention was excellent with average retest grade of 96%. The learning effectiveness through SQ5R proven by the increase of average pretest grade from (47,5) to post-test (74,5) with N-gain in medium level (0,5). The result of SQ5R feasibility check list showed that 90,2% of student already carried out SQ5R stage. Based on student responses, application of SQ5R made 47,1% of student enjoy the learning. There were also 94,2% of student said that SQ5R helped them to understand the concept of Human Reproductive System.

Academic self-efficacy of students makes students confident and confident in their ability to solve genetic problems correctly. The purpose of this study is to compare the level of academic efficacy of students who take tutoring with students who do not take tutoring in solving genetic problems. The research method used, namely quantitative comparative research. The study population was students of class XII in Majalengka Regency. The sample consisted of 240 students who were divided into two groups, namely participant and non-participant tutoring. The research instrument used a questionnaire consisting of 74 items that have been declared valid and reliable statements. Data analysis using two independent sample t-test techniques. The results showed that the comparison of the level of academic efficacy of students in solving genetic problems in terms of participation in tutoring showed a significant difference (p <0.05). Participants tended to have higher levels of academic efficacy on all dimensions of academic efficacy, namely level, strength, and generality compared to non-participants. The conclusion of this study was that there were differences in levels of academic efficacy between students who took tutoring and did not.

The digital technology enhancement occur rapidly providing various way and society’s reading behavior. Based on research survey, we analyze students preferences of using e-textbook or printed textbook. This research was a quantitative descriptive study that using 180 of 12th grade in 2018/2019 academic year as the subject. Quantitative data collected through filling questionaire. The instrument used a perception questionnaire that had Cronbach alpha 0,76 which means a good internal consistency. Instrument validation was through expert judgement. Finding indicated that students’ preference for e-textbook is higher in many aspects of praticality, quality of visual representation and availability of features that support reading strategies such as taking notes and highlighting essential concept. Students who had previously experience used e-textbook do not prefer e-textbook over p-textbook for learning Biology concept.
