TL;DR: In this paper, the authors used approach of mix method of sequential explanatory type to test the effectiveness of project based learning model with scaffolding in improving mathematical communication skills, and to describe students' curiosity.
Abstract: This study aims to: (1) test the effectiveness of project based learning model with scaffolding in improving mathematical communication skills, and (2) to describe mathematical communication skills and students' curiosity through the project based learning model with scaffolding. This research uses approach of mix method of sequential explanatory type. The subject of the research are the students of VIIA class of State Junior High School 18 North Halmahera academic year 2016/2017. Techniques of collecting data by using tests, observations, questionnaires and interviews. Data were analyzed by descriptive analysis and statistical test of t comparison and regression effect test. The results showed that the model of project based learning with scaffolding was effective on mathematical communication ability. Mathematical communication skills and the curiosity character of upper and middle group students are categorized as good and in the high category, while the lower group is considered poor and still in low category.

TL;DR: In this paper , the design of an e-module using the kvisoft flipbook maker application based on mathematical creative thinking skills is appropriate for use in the learning process for class VIII number pattern material.
Abstract: Mathematics learning innovations in teaching materials used in schools are still in the form of printed books from the government. In 4.0 era, the use of technology can be used to make teaching materials in the form of e-modules or electronic modules using the Kvisoft Flipbook application. The purpose of this study was to determine the validity, practicality, and student responses to the design of the number pattern e-module based on mathematical creative thinking skills using the kvisoft flipbook application so that it can be used as a learning resource for students both in the classroom learning process and independent learning. The method used in this study is a research and development (R&D) method using the ADDIE model. The data collection technique used is through a validation questionnaire, user practicality questionnaire and student response questionnaire to e-modules. The results of the study show that this e-module is very feasible to use with the results of material expert validation, media expert validation, user practicality, and student responses to e-modules. Based on the results of this study, the design of the e-module using the kvisoft flipbook maker application based on mathematical creative thinking skills is appropriate for use in the learning process for class VIII number pattern material

TL;DR: A detailed survey was conducted at Dahapara village of Murshidabad district to assess the present condition of the area giving emphasis on the identification of sources of arsenic pollution.
Abstract: According to WHO, the permissible limit of arsenic till 1993 was 0.05 mg. /L of drinking water. In 1993, WHO modified the maximum level and brought it down to 0.01 mg./L. According to the report of School of Environment Studies of Jadavpur University (1992-1993), West Bengal has 6 districts, affected by arsenic contamination of ground water. The present paper attempts to find out the vulnerability and impact of arsenic on human being. A detailed survey was conducted at Dahapara village of Murshidabad district to assess the present condition of the area giving emphasis on the identification of sources of arsenic pollution.

TL;DR: In this paper, Syamsudduha et al. used quasi-experiment with a quantitative approach to analyze the improving of mathematical communication skills of students, the learning acktivities of student and student's response at realistic mathematics learning.
Abstract: The purpose of this study is to analize the improving of mathematical communication skills’s students, the learning acktivities of student and student’s response at Realistic Mathematics (RME) learning. The research is held at MTs.S Syamsudduha in 2018-2019 years, which using quasi experiment with a quantitative approach. This study used two samples, they are experiment’s class as treatment class consists of 34 students and control’s class which not give the treatment consists of 36 students which the sample was taken in this research used the technique sampling purposive. This data was obtained with test technique and observation sheet. Data is analyzed with t test using SPSS 18, the result show that there is an increasing of mathematical communication skills of student on statistical study with the Realistic Mathematics Education (RME) learning. This shows that value of n-gain on student’s mathematical communication skill for experiment’s class is 0,49 and control’s class is 0,17 with significant 0,000 < 0,05, thats mean there is an increasing in the learning process. So, RME learning can improve student’s mathematical communication skills of students better than students who is taught by conventional learning.

TL;DR: In this article, a quantitative analysis using a test independent sample t-test was conducted to evaluate the effect of react strategy on the creative thinking ability of students in the SMAN 1 Banda Aceh class.
Abstract: The ability to think creatively is important to create students who can use mathematical mindset in their daily activities, and in various sciences. The conditions at school this time show us that students still run into problems in resolve math questions which related to mathematical creative thinking ability that finally impact on the result is low for this ability. Therefore, we need strategy for mathematics learning so it can improve mathematical creative thinking ability for students. The strategy that can be applied are through Relating, Experiencing, Applying, Cooperating, dan Transferring (REACT). This research aims to know the improvement creative thinking mathematical ability for students through react strategy. The type of this research is experimental research with a quantitative approach. The populations in this study are students in class X SMAN 1 Banda Aceh. The sample in this study is students in class X MIA-3 as an experimental class that gets learning with REACT’s strategy, and students in class X MIA-1 as a control class that has conventional learning. The instrument of this research is the questions of pretest and post-test. The quantitative analysis using a test independent sample t-test. Based on the results of data analysis it can be concluded that improvement creative thinking mathematical ability for students by teaching with REACT’s strategy is better than improvement of students' creative thinking skills by teaching conventionally.

TL;DR: In this paper, a study aimed to establish the impact of applying religious values through online Problem-Based Learning (PBL) among undergraduate students, and the results showed that there was a significant effect on the applying all religious value in the treatment group.
Abstract: Implementing religious value can develop good attitude and behaviour. It can be implemented in various ways such as in speech, behaviour, gesturing, comprehension and assessment. This study aimed to be establish the impact of applying religious values through online Problem-Based Learning among undergraduate students. A total of 81 students were involved in the study and were divided into treatment and control groups. In order to identify the effectiveness of the module in applying values, the quasi-experimental method was used through questionnaires. The results showed that there was a significant effect on the applying all religious value in the treatment group. The finding also revealed that learning through Problem-Based Learning (PBL) can provide a different learning environment as compared to regular learning sessions. The implications of this study can directly provide an alternative in applying values to students in the higher learning institution.Â
