Abstract
The development of mathematics’ teaching material using project-based learning integrated with science, engineering, and technology (STEM) is a new thing to do. In its development, teaching materials through two series, namely the preparation and development then validation of teaching materials that have been developed. This research was conducted to determine the validity value of mathematics teaching materials based on project integrated with STEM. The data of this study were obtained from the assessment of mathematicians who acted as material experts and media experts to determine the face validation, content validation, and construct validation. The validation by 36 junior high school students was conducted to find out the value of content validity in each part of evaluation to ensure the learning objectives could be achieved. The results of the experts judgement and 36 junior high school students can be concluded that the teaching materials being developed have a high value of face validation, content and constructs. Based on these results, mathematics teaching materials that are developed feasible and valid for use in a broad scope of research or furthermore are worthy of being used in the learning process of teaching mathematics on appropriate topics.

Abstract
This research is a qualitative descriptive study that analyses the Pedagogic Content Knowledge of prospective mathematics teachers in the practice of learning in secondary school Cirebon. Nine students are taken as participants of the study based on high, medium and low academic ability levels. The instruments were questionnaires and observation sheets in the form of PCK measurement instruments that had been designed for prospective mathematics teachers and were declared valid. The results of the study show that prospective mathematics teachers with high academic abilities have good abilities in compiling learning devices and PCK. For prospective teachers with moderate academic abilities are still relatively good in preparing learning tools, but the ability of PCK is still quite sufficient. Whereas prospective teachers with low academic ability are still quite sufficient in compiling learning tools and PCK abilities.

Abstract
The purpose of this research is to determine the model and utilization of the information communication technology (ICT) that effectively improve the science process skill (SPS). The method used is quasi-experiment. The sample was selected using purposive sampling technique as many as 12 classes of junior high schools in Lampung Province with average initial ability were equivalent. The material that is learned is about the measurement. Data were collected using SPS observation sheet and analysed using two-way ANOVA. The first factor is ICT media model those are the tutorial and the simulation media model of measuring instrument. The second factor is the utilization model of ICT media those are the substitute-experimental, the substitute-demonstration, the complement-experimental, the complement-demonstration, the supplement-experimental, and the supplement-demonstration. The result of the research shows that there is no difference of SPS caused by the difference of ICT media model, there is a difference of SPS caused by the different model of ICT utilization. There is an interaction between media utilization model and ICT media model in terms of SPS. The highest SPS was obtained from the learning using the tutorial media model that was learned as a supplement using the experimental method.

Abstract
The abilities that students must possess as a result of learning are to have critical and creative thinking skills, communication skills and collaborative skills. These skills are called 21st century skills. Those skills are very important to be trained during the learning process. Ones of learning models that considered effective for trained 21st century skills is the OIDDE model. To know the effectiveness of the model, we used reading infusions strategy as a comparison. after learning, students that learning with OIDDE and reading infusion models have increased and get higher score of critical thinking skills and creative thinking compared to OIDDE classes, as well as acquired skills profiles of communication and collaboration skills. Hypothesis test using ANOVA shows the average difference. The effectiveness of the model is shown by the value of d-value with the weak category.

AbstractVirtual laboratories have been developed in this study as an alternative to the limited equipment of physics experiments. This study aims to examine the effectiveness of virtual lab models to improve creativity and problem-solving skills for prospective physics teachers. The research and development have been divided into 3 phases namely, preliminary study, design development, and model testing. Model testing was performed on two groups of thermodynamic courses using a pre-test post-test control group design. The instruments that have been used are creativity tests and problem-solving tests in the form of essays. Instruments of creativity include verbal and figural aspects. Each data was analyzed using t-test and normalized gain score. The results showed that there was an increase in creativity and problem-solving skills in both groups. The creativity of students of the experimental group was higher than the control group. Student problem-solving skills in the two groups differed significantly. The experimental group has a higher problem-solving ability than the control group. This suggested that the developed virtual lab model proved to improve the creativity and problem-solving skills ability of prospective physics teachers.

Abstract
Mental models aid us to comprehend the establishment of objects, the progress of the process and to assert a notion about a certain concept. This study consigns to investigating the mental model used by K-11 students in describing the hydraulic system. Research methods utilized the case study. The age of the participants is between 16th and 17th-year-olds (N = 105) of the eleventh graders in one of the Secondary Schools in West Java. The data unruffled through Two-Tier Open-Ended Tests (2TOET) was analyzed both quantitatively and qualitatively. Through quantitative analysis, the descriptive mental model is more widely used than the exploratory mental model. The results assert that the participants built a diversity of mental models about system hydraulic and almost all students including defective mental models rather than a scientifically appropriate one.

Abstract
This paper aims at the problem of the generalized modeling considering the capacity limitation of inverter. Firstly, how the inverter capacity limitation can influence the generalized load fault response of the grid-connected point was analyzed. Then, the idea of fitting the piecewise function was proposed and applied to the training process of the generalized load artificial with neural network class model. To be clearer, fault samples were jointly trained at the same time to learn different segmentation characteristics. The modeling and simulation results show that the proposed method can improve the generalization ability and stability of the artificial neural network class model in generalized load modeling.

Strategies to Fabricate Flexible SnO2 Based Perovskite Solar Cells Using Pre-Crystallized SnO2
Authors: Liu Detao , Chen Hao , Ahmed Yameen , Li Shibin 
Published: November 2019

Abstract
Perovskite solar cells (PSCs) have attracted much attention since the first report. Flexible PSCs are one of the important development orientations due to its light weight. However, a low temperature process is essential to fabricate the flexible PSCs due to the deformation of the plastic substrate. Here, the pre-crystallization SnO2 colloids have been used to deposit the electron transport layer of flexible PSCs. The photovoltaic performance of flexible PSCs has been optimized through controlling the annealing temperature and SnO2 thickness. A moderate annealing temperature reduces the deformation of flexible substrates and protects the conductive layer. A SnO2 film with a suitable thickness not only blocks the direct contact between perovskite and electrode, but also transports the electron from perovskite to anode efficiently. As a result, the power conversion efficiency of the champion PSCs has been improved to 11.61 %.
