This research was conducted to: (1) design a Schoology-based blended learning media for Basic Physics I course on the topics of vector quantity, linear motion, and translational dynamics, (2) describe the validity of the product, (3) describe the product's effectiveness in enhancing students' conceptual understanding and problem solving skills, and (4) describe students' responses towards the media and blended learning model. The development procedures employed were ADDIE model which consisedt of five stages: analysis, design, development, implementation, and evaluation. In development stage, the assessment had been conducted by two experts to assess validity of media both in content and construct aspects. The results showed that the validities in content aspect and construct aspect were "very good" and "good", respectively. The results from classroom implementation revealed the effectiveness of the product in enhancing students' conceptual understanding and problem solving skills. Students' responses towards the product's utility, attractiveness, and easiness as blended learning media were also positive. The conclusion was that the media was valid and effective as blended learning media of Basic Physics I course.

This research aimed to find out the effectiveness of Flipped Classroom model to self efficacy and student concept mastery. This Research was conducted at SMAN in Bandar Lampung. The sample of this research was 22 students of X MIA1 as an experimental class and 21 students of X MIA2 as a control class. The research design used was Pretest-Posttest Control Group Design. Based on the result of self efficacy ANCOVA test with Fcount>Ftable  (15,28>4,09) and the result of concept mastery with Fcount>Ftable  (15,49>4,09),  it can be stated that  there are differences in mean of self efficacy and mastery of student concepts in the experimental class and control class which means that Flipped Classroom gives a significant impact to the self efficacy and student concept mastery. The conclusion of this research is Flipped Classroom learning model can improve self efficacy and ability to master student concept, this is indicated by the average difference of N-Gain self efficacy in experimental class 0.75 with high category and N-gain mastery of concept in experimental class 0,70 with high category.

This study was aimed to determine the effect of POE learning model on science process skills of high school students in the material of Newton’s Law motion. The study might benefit to a provide different learning experience that makes students become more active in learning and to improve students' science process skills towards the material being taught. The populations in this study were all students of class IPA X of SMA 5 Bandar Lampung in the even semester of the Academic Year 2018/2019, consisting of 6 classes with a total of 203 students, with samples of class X IPA 1 as the experimental class and X IPA 2 as the control class. Research method of the study was quasi-experimental. The research used a pretest-posttest control group design. The result of the study revealed that the control class using the conventional learning model had an average N-gain of 0.42, while the experimental class using the POE learning model had an average N-gain of 0.72. The effect size in this study, which was 0.71, indicated that the POE learning model has a high effect in this study.  Based on the hypothesis test, it can be concluded that there was an effect of applying the POE learning model to students' science process skills in the material of Newton's Law. The magnitude of the influence of the POE learning model was classified into the high category with the Cohen’s d value of 3.40 and the effect size r of 0.71.

This research aims to develop worthy (in terms of validity and practicality) Electronic Student Worksheets (E-Worksheet) based project using FlipHTML5 in light interference topic. E-Worksheet developed to stimulate student’s science process skills. This research used design and development research (DDR) which consisted of 4 stages, namely analysis, design, development, and evaluation. The results of the product validity were assessed by experts consisting of two high school physics teachers and a lecturer from the physics education department of the University of Lampung who got an average score of 3.56 with the very valid category. The E-Worksheet practicality in terms of the legibility, the student views that was completed by 9 students, and the teacher views that was completed by 5 high school physics teachers got an average percentage of 90% with the very practical category. These results showed that E-Worksheet were valid and very practical to stimulate student’s science process skills. Based on teacher views, the E-Worksheet is very possible to be implemented in online and face-to-face learning especially in the covid-19 pandemic era. The E-Worksheet can be used as multimedia to support online learning.

The Development of Student Worksheet Based on POE for High School Momentum andImpulse Material. Learning model supported by good learning media is needed to improve the effectiveness of momentum and impulse learning material. The aim of this research were to develop student worksheet based on POE for high school impulse and momentum material that are validated. This study uses the ADDIE development model, which starts with need analysis, then designs, develops and validation tests, and implementation to find out the attractiveness, easiness, usefulness, and effectiveness of the product. The results show that student worksheet validated (89,11), very interesting (3,40), very easy to use (3,28), useful (3,10) and proven effective use in the learning shown by 82,75% of student reached the standard of minimum score.Abstrak: Pengembangan LKPD Berbasis POE Untuk Pembelajaran Fisika Materi Momentum dan Impuls SMA.
