Abstract
The challenges of 21st century globalization require students to have various skills needed in compete at the global level. One of the 21st century skills students need to have is critical thinking skills, but student-s critical thinking skills in Indonesia are still relatively low. To develop this skill, learning is needed along with appropriate assessment. The application of formative assessment in learning is one of the efforts in developing the skill. Through formative assessment, teacher can make appropriate learning strategies to facilitate student learning needs. However, the practice of assessment for learning rarely facilitates student learning needs. Thus, this study was needed for investigating the effect of formative assessment in develop critical thinking skill of students. The quasy experiment method is used in this study with the pretest posttest control group design. The experimental group was given the application of formative assessment through oral feedback during learning, while the control group was given the conventional assessment. The result showed that formative assessment through oral feedback can develop critical thinking skill of students, indicated by the experimental group has higher critical thinking skill improvement than control groups in Spermatophyta and Bryophyta chapter.

Abstract
The purpose of this study was to describe the implementation of skills assessment based on the 2013 Curriculum in one of the Bandung State Middle Schools. This study is descriptive qualitative research. The study was conducted in the even semester of the school year 2019/2020 with research informants are 2 mathematics teachers who teach mathematics in class VIII. The data were collected by using observation and interview. The results of this study are that the teachers only carry out the assessment of practices, products, and portfolios. The implementation of this type is carried out without using the rubric assessment. This is because the teachers have the difficulties in preparing objective assessment rubrics even though the school has implemented In House Training. This is because there is rarely an evaluation of In House Training. By carrying out an evaluation of the In House Training, it is hoped that it can help teachers in developing skills assessment rubrics so that they can carry out skills assessments properly.

Abstract
The purposes of this study were to describe the implementation of STEM learning by using toy projects and describing students perceptions of these learning. This study used a mixed research method. In the process of describing the learning process, the qualitative method was used and followed by quantitative methods to describe students perceptions. The instruments used were observation sheets and video recorder. For the quantitative, questionnaire was used. These were perception questionnaires consisting of 7 indicators. This questionnaire was adapted from Korpershoek (2013). The results of this study showed the process of implementing learning was well-acceptable. However, the teacher was very constrained in carrying out to assess the learning process. Meanwhile, from the results of quantitative data, the data analysis proved students agree that this learning was easy, interesting, focused, did not contain many theories, fitted to them, and also well-achieved or able-followed the learning process. On the other side, students could not determine whether this learning had varied content or not. This is indicated by the average student choosing neutral for this indicator.

Abstract
Based on a preliminary study conducted in one of the international schools in Bandung, the implementation of STEM is only done once a semester. The perceived constraints are the unavailability of teaching materials. Science learning that is integrated with engineering design will facilitate students to be able to make product designs. STEM learning with engineering design will train students to use scientific and mathematical knowledge in making products. This will make learning more meaningful in overcoming real problems even by professional engineering workers. By using quantitative descriptive methods, showing the results of the average value of 8.25 engineering abilities, the feasibility of teaching materials in the category is very feasible and the understanding of students is 94%.

Abstract
The study in Aerodynamics has shifted from large theoretical curriculum into authentic learning experiences in response to the industry requirement. In addition, the development of computational methods has revolutionized the design cycle in aerodynamics. This work describes an integrated approach in an undergraduate Aerodynamics course using the Kolb-s Learning cycle. Experiential learning is incorporated in the class to provide more opportunities for students to understand the theoretical concept through experiencing the applications and impact of the concept in real life. The Finite Element Method (FEM) which is widely used in analyzing many engineering problems was integrated into the Aerodynamics theory and application to visualize changes of parameter in the design phase. The main learning objective of the developed learning module is to apply appropriate aerodynamics models to predict the forces on and performance of a vehicle design. The module is assessed by instructor before being applied for the students in the classroom. It is considered to be an effective method for learning when lectures and computation works are integrated in a meaningful manner. This development research is expected to be able to produce graduates who are competent in the field of design.

Abstract
The aim of this study was to improve the mental model of high school students related to the concept of global warming through the application of the CBL model using the CM2RA strategy (context, microscopic models, macroscopic phenomena, and analogy representation). The mental model categories reviewed include scientific, synthetic and initial mental models. This mental model category is determined based on the test results data level of concept understanding. A pre-experiment method with one group pretest-posttest design was used in this research. The number of research subjects was 40 students consisting of 24 female students and 16 male students, in one of the high schools in the Tasikmalaya district of West Java province. The instrument used to collect data is a test of understanding the concept of global warming in the form of essays covering four aspects of the question. The results showed that before the application of CBL, the number of students in each mental model category was: scientific mental model (5%), synthetic (40%), and initial (55%), whereas after the application of CBL, the number of students in each category of mental models becomes: scientific mental model (78%), synthetic (15%), and initial (7%). These results indicate that the implementation of CBL with the CM2RA strategies has high effectiveness in facilitating the achievement of the scientific mental model.

Abstract
Argumentation skills are an important practice in science in the 21st century to develop analytic skills and engage in arguments that can construct scientific explanations, develop critical thinking skills and evaluate alternatives. Science learning with guided inquiry model is able to facilitate students in learning to argue. However, good learning must be supported by good teaching materials. So the purpose of this study is to develop junior high school science teaching materials to improve students ability to argue. This study uses the Research and Development (R & D) method which was adapted from Borg & Gall. The parameters used to determine the quality of teaching materials developed are validity and practicality. The validity and practicality of the teaching materials developed were analyzed using Aikens V. The results of the feasibility test based on the results of expert validation were obtained by Aikens V of 0.75 with valid criteria, while the practicality test results based on teacher and student responses obtained Aikens V scores in a row 0.84 (very practical) and 0.80 (practical). Based on this, it can be concluded that the teaching materials developed meet the criteria for developing quality products that are valid and practical.

Abstract
This study aims to determine the increase of student learning activeness through the demonstration method of concrete objects in the line and angle material in Junior High School. This type of research was Class Action Research conducted collaboratively between teacher and researcher at MTsN Batang Toru. The research subjects were 40 students of class VII-4. Data collection techniques were carried out by observation and distribution of questionnaires. The data analysis technique used is the analysis of the Miles and Huberman models with three stages, namely data reduction, data display, and drawing conclusions. This research through three cycles to obtain the desired results. The results of this study indicate that student learning activeness increases significantly. The results of the observation during the learning process showed the observations of the first cycle, the first meeting, the activity of students was 34.82%, and the second meeting was 42.33%. The 1st cycle of the 1st meeting was 51.5%, the second meeting was 63.83%. The third cycle of the 1st meeting was 74.16%, at the second meeting increased by 85.16%. Moreover, measuring the level of student activity was carried out by distributing questionnaires at the end of each cycle. The results of the questionnaire showed that respectively in the first cycle reached 44.16%, the second cycle 64.16, and the third cycle 84.33%. It can be concluded that the activeness of students in line material and angles in mathematics lessons using the concrete object demonstration method increases as expected.

Abstract
The present study is aimed at investigating the influence of Concrete Pictorial Abstract (CPA) approach to the improvement of elementary school students- Self Efficacy Mathematics (SEM) seen from Mathematical Prior Ability (MPA) and as a whole. It is a quasi-experiment with control design of pre-scale and post-scale in Mathematics in the topic of 3 dimension geometry (3D geometry) to 119 elementary school students in Puwakarta Subang Bekasi (Purwasukasi), West Java. The present study is conducted by using two study groups, a group which implements CPA learning approach as the experimental group and group which implements conventional learning as the control group. Both descriptive and inferential data analysis show that the improvement of students- SEM is better in students with CPA learning approach rather than students with conventional learning, seen as a whole and in every MPA. Therefore, CPA learning can improve elementary school students- SEM.

Abstract
The environmental issues that happened in the northern part of Central Java are getting worse. Human activity is believed as the main factor of environmental damage. The developing in infrastructure, changing the coastal area into harbor and industry and also habit in throwing waste material into the sea will contribute great damage in the environment. Then, preventive action is needed to overcome this problem. By changing the young generation-s perception, awareness, and action with the integration of environmental literacy in learning practice will become the best way to fix these challenges. This research is aimed to develop environmental literacy-integrated learning in high schools and measure student-s environmental literacy as a result of the implementation of this integrated learning. The environmental literacy-integrated learning combines environmental literacy aspects with problem-based learning model. In addition, a set of learning media and module based environmental literacy are used as supporting materials in this research. This research use mix method with a qualitative approach to examine the quality of the environmental literacy-integrated learning. The quantitative approach also used with quasi-experimental design to measure the effect of environmental literacy-integrated learning which involving 30 students in the experimental class and 30 students in the control class. The score of environmental literacy is taken after the implementation of environmental-integrated learning using Middle schools environmental literacy surveys (MSELS) questionnaires. The data then analyze using ancova. The qualitative data is also used to evaluate the implementation of environmental literacy-integrated learning. The result shows that environmental literacy-integrated learning gives positive impact in student-s comprehension in all environmental literacy aspects. In addition, a statistical analysis also shows significant value as 0.000 (p< 0.05). This result indicates that environmental literacy-integrated learning can improve student-s environmental literacy.
