<![CDATA[The purpose of this research to describe the effectiveness of the learning model in improving problem solving skills and mastery of concepts to classify colloidal material. Learning model of problem solving is one of constructivism based learning model consists of five phases. The research was done in class XI High School IPA4 YP Unila Bandar Lampung. This study used a pre-experimental method with One Group Pretest Posttest Design. The effectiveness of the learning model of problem solving is measured by the difference in the mean score of the pretest and posttest as indicated by the value of n-Gain skill grouping and mastery of concepts, 0.41 and 0.29. Based on the study hypothesis testing, the results obtained after using a model of learning problem solving skills and his mastery of concepts classify higher than before the learning model of problem solving. This suggests a model of learning by effectively increasing the skills of problem solving and concept mastery group class XI science in colloidal material. Penelitian ini bertujuan untuk mendeskripsikan efektivitas model pembelajaran problem solving dalam meningkatkan keterampilan mengelompokkan dan penguasaan konsep pada materi koloid.

<![CDATA[The design of this research is survey research. This study aimed to explore seventh-grade science teachers’ perception of laboratory activity on mixture separation topics and match them with available evidence from learning document. The sample comprised 10 seventh grade science teachers, purposively sampled from seventeen teachers. Questionnaires and interview guidelines were used to collect data. The results show that while teachers’ perceptions of mixture separation topics in science classrooms are inadequate. Caused, there was a mismatch between teachers’ perceptions, learning document, and what was taking place in the science classroom. The study may inform teachers’ performance in teaching mixture separation topics in science. It is recommended that teacher on learning should be used to practice worksheet and assessment of laboratory activity, as most of the teachers do not record marks regularly for laboratory activity. Furthermore, laboratory activity prepared by the teacher should be arranged in a lesson plan and practice schedules.]]>

<![CDATA[Model pembelajaran berbasis proyek atau project based learning (PjBL) merupakan model pembelajaran di mana siswa mendapatkan pengetahuan dan keterampilan melalui suatu proyek dalam jangka waktu tertentu, untuk menyelidiki dan menanggapi pertanyaan kompleks. Pada model ini, pembelajaran dirancang berdasarkan masalah kehidupan nyata dan bersifat ill-structured, sehingga siswa menjadi terdorong lebih aktif dalam belajar dan kreativitas siswa menjadi berkembang. Akan tetapi faktanya kemampuan guru dalam menerapkan model ini relatif rendah. Untuk itu perlu dilakukan pelatihan penyusunan LKS berbasis model PjBL. Tujuan dari kegiatan pelatihan ini adalah meningkatkan pemahaman guru IPA tentang model PjBL, dan keterampilan guru IPA dalam menyusun LKS berbasis PjBL. Metode pelatihan yang digunakan adalah ceramah, diskusi, dan pendampingan. Kegiatan ini dilaksanakan di gedung G FKIP Universitas Lampung. Sasaran dari kegiatan ini adalah guru-guru IPA yang tergabung dalam MGMP IPA Kota Bandar Lampung dan Kabupaten Lampung Selatan. Model evaluasi program yang digunakan adalah model evaluasi Context, Input, Process, Product (CIPP). Berdasarkan hasil evaluasi, dapat dinyatakan bahwa terdapat peningkatan pemahaman guru tentang model PjBL, hal ini terlihat dari peningkatan nilai postes dibandingkan nilai pretes dengan n-gain rata-rata sebesar 0,88 (kategori tinggi); dan meningkatnya keterampilan guru dalam menyusun LKS berbasis model PjBL DOI: https://doi.org/10.23960/rp/v1i2.hal.74-81]]>

<![CDATA[Abstract: This study aims to describe the effectiveness of the inquiry lesson model on the buffer solution material to improve students' critical thinking skills. The research sample was grade XI students of a senior highschool in Bandarlampung which obtained by using purposive sampling technique. In the control class, direct instruction learning was applied and in the experimental class was the inquiry lesson. The research used a quasi-experimental design with The Matching-Only Pretest- Post-test Control Group. The research data were analyzed using the n-gain calculation and parametric statistics with the t-test. The results showed that the post-test average score of critical thinking skills in the experimental class and the control class had a significant difference and the average n-gain in the experimental class was 0.48 (moderate category). Thus, it can be concluded that the Inquiry Lesson model is effective for improving students' critical thinking skills.Keywords: Inquiry lesson, buffer solution, critical thinking skills Abstrak: Penelitian ini bertujuan untuk mendeskripsikan efektivitas model inquiry lesson pada materi larutan penyangga untuk meningkatkan keterampilan berpikir kritis siswa.

<![CDATA[The objective of this research was to investigate the Science teachers' perception toward e-worksheet based on chiken manure waste treatment projects to improve students' creative thinking skills. The method used in this research is mixed methods with Sequential Explanatory Design. The data was collected through questionnaire, then analyzed by using descriptive analysis. The questionnaires were distributed to 14 Science teacher respondents and 127 junior high school students in North Metro District. The result shows that teacher have a positive perception toward usage of the electronic students' worksheets based on chiken manure waste treatment projects. The results showed that 79% of teachers had not used project-based e-worksheets; based on students' response questionnaires, 37% of teachers have given project assignments, but the projects were not based on real problems in the environment. Environmental problems that occur in North Metro District is the amount of chicken manure waste issue that causes pollution to the environment around society’s houses. The current worksheets has not completely train students' creative thinking skills and that's skills was in low category. Based on the result It can be concluded that a e-worksheet based on chiken manure waste treatment projects is needed to improve students' creative thinking skills]]>

<![CDATA[This research aims to find out more about teacher perceptions in students' scientific creativity as a basic for project-based learning models as well as provide information about the use of project-based learning programs that are in accordance with PjBL syntax at the junior high school level in Metro City. This research is a type of qualitative research with a case study approach, data collection techniques used are interviews (interviews), observation and documentation. Then to ensure the validity of the data using technical triangulation and source triangulation followed by data analysis with the research flow, namely identifying problems, determining research designs, determining research roles, determining data collection procedures, data recording, data analysis and verification, and narrating the research results obtained. The results of this research indicate that 54% of teachers have not used the PjBL learning model in learning and the teacher's perception of PjBL is good, but 62% of teachers do not know the PjBL syntax that must be fulfilled in using this learning model. In relation to scientific creativity, teachers do not know what indicators must exist in assessing students' scientific creativity]]>
