Abstract:
A mathematical statement is not a theorem until it has been carefully derived from previously proven axioms, definitions and theorems. The proof of a theorem is a logical argument that is given deductively and is often interpreted as a justification for statements as well as a fundamental part of the mathematical thinking process. Studying the proof can help decide if and why our answers are logical, develop the habit of arguing, and make investigating an integral part of any problem solving. However, not a few students have difficulty learning it. So it is necessary to explore the student's thought process in proving a statement through questions, answer sheets, and interviews. The ability to prove is explored through 4 (four) proof schemes, namely Scheme of Complete Proof, Scheme of Incomplete Proof, Scheme of unrelated proof, and Scheme of Proof is immature. The results obtained indicate that the ability to prove is influenced by understanding and the ability to see that new theorems are built on previous definitions, properties and theorems; and how to present proof and how students engage with proof. Suggestions in this research are to change the way proof is presented, and to change the way students are involved in proof; improve understanding through routine proving new mathematical statements; and developing course designs that can turn proving activities into routine activities.

Abstract:
Sensitivity, knowledge, belief, and behavior to the environment will bring out good behavior that leads to environmental literacy (EL). This study aimed at analyzing the students’ EL based on the multidimensional perspective. This study comprised of two types, namely library and field research. Questionnaire was developed from The Second Minnesota Report Card on EL. This study was conducted in FKIP-UMM at undergraduate level, from July to October 2020. The types of data were in the form of qualitative and quantitative. The data were obtained from the results of Google Form. The population of this study was the students of FKIP-UMM, in which it consisted of 2.750 students. The subjects were chosen randomly by sharing the link of Google Form thru the WhatsApp group so that 139 students (5%) were obtained. The data and EL findings were analyzed descriptively qualitative analytic. Scaling multidimensional analysis was carried out by using ordination that continued with scaling and percentage processes. The results indicated that (1) Environmental sensitivity tends to show various conditions. (2) Environmental knowledge also tends to vary. (3) Environmental beliefs tend to be good. (4) Environmental behavior in students tends to be good.

Abstract:
Various previous studies have shown that ecotourism has great potential and benefits when associated with education and especially in learning. This review study aimed to explore an ecotourism-based learning model at the high school level in Malang, East Java. The focused in the review were (1) competencies and indicators of learning outcomes of all subjects in all subjects that could apply ecotourism-based learning 2) the potential for regional ecotourism (especially school environments in East Java) which could be used for ecotourism-based learning based on competencies and outcome indicators learning, and 3) drafted recommendations for learning models based on ecotourism. Based on the results of a review of various references, it can be stated that four things need to be considered in the application of an ecotourism-based learning model, namely the conceptual framework, planning, implementation, evaluation, and furthering the ecotourism-based learning model. Furthermore, It was necessary to develop an ecotourism-based Learning Model that follows an appropriate development model, so that an implementable model is produced.

Abstract:
The low utilization of technology and scientific literacy skills lacking in the classroomsremaina major problem in the learning and teaching process, specifically in influencing students' conceptual understanding. This research aims to analyze the effect of Diboracy (Digital Book Contained Scientific Literacy) in reducing misconceptions in Newton's law of gravity. This research uses experimentalresearch design with one group pre-test-post-test conductedon research subjects which were selected through random sampling technique. The sum of the research subjects include 38 students. The data instruments include tests and non-tests instruments. The test distributed is in the form of multiple choice questions equipped with CRI to measure the misconceptions, while the non-test assessmenttakes form of questionnaires to determine students’ responses to Diboracy. Data analysis was performed through t-test on student learning outcomes and the students’ questionnaire responseswhich resulted in the average percentages. Based on the analysis, it can be concluded that: (1) there is an effect in reducing students’ misconceptions when Diboracy is implemented, specifically regarding Newton's law of gravity; (2) students give better responses to Diboracy than textbooks.

Abstract:
Strengthening ecopreneurship plays an important role in preparing students for success in the life and career of students, but this skill is not well trained in learning physics. Therefore, the purpose of this study was to analyze the impact of environment-based physics learning on students' mastery of concepts and ecopreneurship. This research is a quasi experimental research with one group pretest and posttest design. The research subjects were 29 students of the physics education study program, Surabaya State University, Indonesia, who programmed basic physics courses. The data collection technique used a conceptual mastery test instrument and ecopreneurship. The data analysis technique used the Kolmogorov-Smirnov test, Paired t-test, Wilcoxon test, and N-Gain. The results showed a significant increase in students' mastery of concepts and ecopreneurship at α = 5%, with mean N-gain of 0.63 and 0.60, respectively, within the moderate criteria. Thus, environment-based physics learning has a significant impact on increasing student mastery of concepts and ecopreneurship.
