Abstract
Related to face the era of globalization where job competence requires someone who is critical, creative, able to work together and able to communicate, learning does not only lead to the provision of knowledge but training skills become important. We call this skill a 21st-century skill (KA21). The quasi-experiment study with 100 samples taken randomly from 288 populations in one of the high schools in Bandung Regency aims to get an overview of the development of the KA21 through the application of IPjBL with a reading infusion strategy and google classroom. The development of KA21 was measured using the rubric adopted and adapted from the Boss and analyzed using the standard developed by Lati, which has been tested with inter-rater reliability technique with the reability of 0.67. The results of the study show the experimental class critical, creative and collaborative thinking skills can increase to good level and communication skills to excellent levels. In the control class, critical thinking skills and creative thinking skills can increase to good level while collaboration and communication skills increase to excellent levels. The conclusion of this study, learning needs to be developed to get wiser ways to train KA21.

Abstract
Abstract. Science literacy is one in HOTS (High Order Thinking Skills). Science literacy is one of the skills needed by students so that students have the ability to solve HOTS problems. One way to measure scientific literacy skills is to use scientific literacy instruments. Several studies have been carried out in the development of scientific literacy instruments, but there are still shortcomings in their development. Some researchers also provide advice on the development of subsequent scientific literacy instruments. There are several shortcomings in existing scientific literacy instruments, including those that have not raised aspects of inquiry, critical insight. In addition, the existing forms of scientific literacy instruments still need development. Then the item analysis method used still uses the classical data analysis method, but some have used analysis items using IRT (Item Response Theory). These shortcomings can be minimized by changing the form of scientific literacy instruments to be more interesting or can measure more than one ability. In addition, the item analysis method of using IRT is one of the recommended methods of data analysis compared to classical analysis methods.

Abstract
In this study, we describe an interesting relationship between uniform circular motion and simple harmonic motion trough simple experiment. The experiment requires a low cost-easily found materials and free software Video Tracker. To represent uniform circular motion, we use a tape stick on a fan moving with constant angular speed. Meanwhile, spring and pendulum motion are used for representing the simple harmonic motion. Through Video Tracker analysis, we showed that the positions (x and y coordinates) of an object moves along a circle with constant angular speed follow a sinusoidal function, as same as, showed in simple harmonic motion. This simple experiment can be embedded in high school physics or introductory physics in college to lead for the students to develop conceptual understanding about uniform circular motion with less mathematical approach.

Abstract
The development of information and communication technology (ICT) has influenced various life activities including human behavior. The use of this technology has increased productivity, but this technology is still deficient to use in education. The teacher must innovate the learning environment to be more comfortable for generally millennial students. One of the learning innovations is the application of the flipped classroom concept. This concept still gives teachers room to face to face in class but also utilizes ICT in activities outside the classroom. From a variety of previous research studies, the application of this concept has a positive impact on various competencies in students. This study aims to see the impact of applying the flipped classroom to improving students critical thinking skills. The research design was the pretest-posttest controlled group design which consists of three groups taught different learning. Teacher applied direct instruction learning at the control group. Two other groups taught using a flipped classroom approach or online using Google Classroom. The participants of this study were 10th-grade students in physics subjects. Samples are taken randomly simple to determine groups. The analysis technique used is ANOVA to know the effect of learning strategies on critical thinking skills. Measurement of critical thinking skills is carried out using critical thinking test questions in the form of descriptions that have previously tested for difficulty and power of difference.

Abstract
Old practices of teaching and learning, mainly based on conventional media, offer a very limited resource in explaining a comprehensive concept of physical phenomena. As a consequence, it needs to incorporate a computer simulation which plays an important role in visualizing a wide range of complicated and abstract concepts. This study aims to develop a computer simulation of gas velocity measurement as a learning medium on the subject of Maxwell speed distribution. Measurement of very small and un-naked eye gas particles requires special techniques and tools that involve a complicated process of selecting particles and measuring their speed. For learning purposes, this measurement process needs to be done by computer simulation as in real lab it still face many limitations. This research uses the ADDIE model which includes analysis, design, development, application and evaluation. The results of the simulation show that: the velocity of gas particles passing through gaps ∆y is not a single velocity but has a certain range (v min - v max), a decrease in angle of two gaps and its width causes a decrease in the speed range, data of particle-s number when angular velocity of disks are varied from 0-100 units shows conformity with Maxwell-s velocity distribution graph which was obtained theoretically.

Students- various conceptions in Physics learning causes the emergence of discrepancy between alternative and scientific conception called as Intermediate conception. This research aims to description of intermediate conception in learning Physics. This research was qualitative research with literature review design. Data collection was conducted by collecting some literatures either articles or books related to intermediate conception. Data analysis was done by conducting analysis and articles and books synthesis and then drew a conclusion. The research results show that intermediate conception can be described as the conception between alternative conception and scientific conception which represent the pieces of ideas or concepts that have lead to science. Intermediate conception can be categorized into; naive physics, phenomenological intermediate primitives, lateral intermediate conception, and ontological intermediate conception.

Abstract
This paper is aimed to design and to implement a new inquiry based laboratory model and cookbook experiment model on a simple concave eyeglasses experiment in Indonesia. The model is a part of experiment models contributing to developing standardization of national experiment examination through revised 2013 curriculum framework. The model has been successfully applied to K-11 in a Private Senior High School. The best achievement of the model is very high with (0.92) item validity as much as its reliability, good (0.50) discrimination power, and medium (0.64) difficulty index. Average student can achieve 72% of experiment process test including finding problems, tools, method, procedure, data, analysis, and conclusion. We concluded that several competences can be trained by using inquiry based laboratory experiment, including understanding experimental problem, determining experimental tools needed, choosing an appropriate method, composing the experiment procedure, collecting data, analyzing data, and writing conclusion.

Abstract
In this increasingly competitive 21st century global economy, it is necessary for students to have adequate skills to cope with demands of 21st century. This quasi-experiment research aims to get an overview of how to train 21st century skills by applying inquiry-project based learning with reading infusion strategy. The participants are 121 students, randomly picked from 288 students at one of the senior high schools in West Bandung district. The development of 21st century skills was measured using rubric adopted and adapted from Boss. The analysis used standards developed by Lati, which have been tested through inter-rater reliability technique with reliability value 0.67. The result shows that in experiment class, collaboration and communication skills can increase to “good” level. However, critical and creative thinking skills are still in “fair” level. While in control class, collaboration and communication skills can increase to “fair” level. But critical and creative thinking skills are declining to “very poor” level. Based on the results, it appears that inquiry project-based learning with reading infusion can help improving the development of certain 21st century skills. Lazy-to-read habit that students do still becomes an obstacle, therefore more appropriate ways are still needed in developing 21st century skills.

Abstract
Smartphone is example of communication technology evolution. At the past time, phone is only used for communication purpose, however nowadays smartphone functions are various. Although still limited, application of smartphone in high school physics is very potential. For physics learning platform, smartphone has some advantages such as it allows physics interactive illustration, it allows students to study anywhere and everywhere, it provides self-evaluation for students, and so on. In this research, we develop smartphone app as learning resource on circular motion topics. Circular motion is phenomenon that closely related to our daily life, however there are some physics quantities which need more visualization, as example is the distinction between linear speed and angular speed. This study aims to develop smartphone app which can improve high school students- conceptual understanding on circular motion. The app includes material, physics animation, exercise, and quiz.
