This study aims to find out (1) the effect of problem-based learning model on critical thinking skill, and (2) the effect of problem-based learning model on environmental attitude. This study employs a quasi experiment model using pretest-postest for control group design. The subject of the study is Social Science Education Department students of Maulana Malik Ibrahim State Islamic University of Malang, Indoensia who were studying in the odd semester of Academic Year of 2018/2019. The numbers of students in experimental and control class are 25 people. The assessment instrument used for environmental attitude is Likert scale, and essay test is used for assessing the critical thinking skill. The data analysis in this study used normality test, homogeneity test, and independent sample t-test. The results of the study indicate that (1) learning activity using PBL model affects the students’ critical thinking, because through PBL learning, students are trained to think critically to solve real problems in groups. 2) The learning activity using PBL model affects the students’ environmental attitude, because the problem solving process in PBL learning encourages students to care about their environment.

Critical thinking skills are very important to have for students given the rapid distribution of information. To promote the critical thinking skills of the student, it could be done by including critical thinking learning in a formal learning environment. However, for the purpose of increasing this skill could be achieved, it required the motivation to learn. This study aimed to increase critical thinking skills and students' motivation through the implementation of an inquiry mind map tool. The study used a quasi-experimental group with a non-equivalent control-group pretest-posttest. The experimental class used an inquiry learning assisted inquiry mind map tool, whereas the control class requires that conventional learning. The sample consisted of 206 students from different schools and different genders. Data on critical thinking skills used essay tests referred to indicators from Sari in 2019. Motivation data learning taken from instrument motivation toward science learning from Tuan, Chin & Shied in 2005. Answers analyzed using ANCOVA. The research findings show that there were differences in the ability to think critically and students' learning motivation using an inquiry mind map tool. The results also examined no difference between school and gender on critical thinking skills and learning motivation. The results of the study show that the inquiry mind map tool was an impact on increasing critical thinking skills and learning motivation. It was recommended to be able to develop more other learning tools and learning model to improve critical thinking skills. Some im-plication was also provided in the article.

The study aimed to determine 1) the effect of digital eco learning in student worksheet flipbooks on environmental literacy projects, and 2) the effect of digital eco learning in student worksheet flipbooks on student ecological competence. The research is a quasi-experimental study using a Pretest-Posttest Non-equivalent Control Group. The research subjects were students in the Environmental Geography course semester 6 of 2020, divided into the experimental and control groups. The research was conducted at the Geography Education study program, Social Science Faculty, State University of Malang, Indonesia. Data were analyzed using the independent sample t-test in SPSS version 23 for windows. The results found: 1) there is a significant effect of digital eco learning with student worksheet flipbook on environmental project literacy competence, and 2) there is a significant effect of digital eco learning with student worksheet flipbooks on ecological competence.

Environmental care attitude is an important factor in protecting the environment. The Adiwiyata Award is presented as the highest recognition for implementing an environmental care attitude. The aims of this study are to (1) evaluate the execution of the environmental curriculum in Adiwiyata schools; (2) to analyze the students’ environmental care attitudes in Adiwiyata schools in the Pati Regency using the new ecological paradigm (NEP) scale; and (3) to examine the students’ environmental care attitudes in Adiwiyata schools in the Pati Regency related to gender differences. Based on the criteria of Adiwiyata schools, they were used as research subjects. The research subjects were chosen using a purposive sampling technique. A questionnaire was utilized as a data collection instrument. The new ecological paradigm (NEP) scale was used to assess environmental care attitudes. This study used a Likert scale to assess environmental care attitudes. The Mann-Whitney test was used to identify gender differences in environmental care attitudes. The results found that (1) Adiwiyata schools in the Pati Regency supported the implementation of environmental education in the curriculum, as well as participation in environmental activity programs and the use of greenhouses; (2) the environmental care attitudes of students from the SMA Negeri Pati Regency were in the moderate category; and (3) there was a gender difference based on environmental care attitudes, which found that female students have a higher environmental care attitude than the male students. Environmental education plays an important role in gender differences because the Adiwiyata school has integrated learning activities with the environmental education curriculum, and participatory-based environmental activities can improve students’ environmental care attitudes. The potential implication for policy and practice in the field is that humans will consciously prevent environmental problems from occurring.

There has been an increasing trend of land area being brought under human’s use over time. This situation has led the community to carry out land-use development activities in landslide hazard-prone areas. The use of land can have a positive impact by increasing economic conditions, but it can have negative impacts on the environment. Therefore, this study aimed to identify the landslide hazard, focusing on the development of a landform map to reduce the risk of landslide disaster in JLS, Malang Regency. The integration of remote sensing and geographic information systems, as well as field observation, were used to create a landform map and a landslide susceptibility map. Using the geomorphological approach as a basic concept in landform mapping, the morphology, morphogenesis, and morphoarrangement conditions were obtained from the remote sensing data, GIS, and field observation, while morphochronological information was obtained from a geological map. The landslide susceptibility map was prepared using 11 landslide conditioning factors by employing the index of entropy method. Thirty-nine landform units were successfully mapped into four landslide susceptibility classes. The results showed that the study area is dominated by a high level of landslide susceptibility with a majority of moderate to strongly eroded hill morphology. It also reaffirms that landform mapping is a reliable method by which to investigate landslide susceptibility in JLS, Malang Regency.

This study aims to describe and test students' perception of scientific learning, students' critical thinking skill level in scientific learning, differences in perception and critical thinking skill level of students based on school differences and gender, and the influence of perception on students' critical thinking skill in scientific approach learning. It involved 206 students from three high schools in Banjarmasin, Indonesia. Quantitative data was obtained from a perception questionnaire and critical thinking skill test. The perception questionnaire refers to Perception of Science Classes Survey (PSCS). The test used refers to indicators of critical thinking skill from Ennis in 2011. Data were analyzed using non parametric statistical tests with the SPSS version 23 application for Windows. The results showed that 1) students' perception of scientific learning were in the medium category, 2) students' critical thinking skill level was in a low category, 3) there were differences in perception and critical thinking skill level based on school, but there are not any differences found based on gender, 4) there was an influence of perception towards students' critical thinking skill in scientific learning approach. Designing innovative learning methods, involving student activity, and providing recommend-ed learning facilities are suggested to do to enhance students' positive perception and critical thinking skill.
