<p><em>Global warming and climate change issues and the impacts become worse recently. This condition needs real actions to maintain sustainable living being. One thing that we can do is developing go green lifestyle  for teenagers . It is important because they are  agent of future change. </em></p><p><em>This project aims to build go green mindset for Senior High School students and encourage them to implement their ideas  become real actions. A series of activities were designed by using active learning approach so the students have active roles in each activity. Firstly, we organise a go green poster competition. Secondly, we installed two  hidroponic sets to make the school greener. The winner of the poster competition became green </em><em>school </em><em>ambassadors who have responsibilty to maintain  hydroponic installation. They also have to do green campaign around their communities. </em></p><p> </p>

The study was report the findings of an only post-test control group research design and aims to analyze the influence of problem-based learning approach, school level, and students' prior mathematical ability to student's mathematics critical thinking ability. The research subjects were 140 grade ten senior high school students coming from excellent and moderate school level. The research instruments a set of mathematical critical thinking ability test, and the data were analyzed by using two ways ANOVA and t-test. The research found that the problem-based learning approach has significant impact to the ability of students' mathematics critical thinking in terms of school level and students' prior mathematical abilities. Furthermore. This research also found that there is no interaction between learning approach and school level, and learning approach and students' prior mathematics ability to students' mathematics critical thinking ability.Keywords: problem-based learning, mathematical critical thinking ability

This study discusses the influence of tactical learning approaches in soccer learning on physical fitness of Sport Senior High School students in Riau. The purpose of this study is to determine the physical fitness that is applied through a tactical learning approach and through a technical approach in soccer learning. The method used in this study is an experimental method. The population in this study were 109 male students of Sport Senior High School in Riau. The number of samples which  30 students was divided by two cells using cluster random sampling. The study was taken for 4 months, which the number of treatments is 16 meetings with a frequency of 3 times a week. The instrument chosen by the author was a physical fitness test. The results of data analysis showed that based on the calculated value and analysis of the calculated t-value obtained, the calculated t-value obtained was greater than t-table at the confidence level α = 0.05 with df (n1 + n2-2) = 28, where t-value (1-1 / 2 @) in the distribution list, the value of t-table is 1.97. Since t-value is greater than t-table 1.761, it can be concluded: (1) The learning approach using tactical approach in soccer learning had an influence on the physical fitness of students of Sport Senior High School in Riau; 2) The learning approach using technical approach in soccer learning had an influence on physical fitness students of Sport Senior High School in Riau. (3) The learning approach using the tactical approach and the technical approach in soccer learning had the same effect on the physical fitness of Sport Senior High School students in Riau. However, the learning approach using the tactical approach gave more significant influence than the technical learning approach in soccer learning.

The study deals with the developing interactive media for senior high school students. The objective of this study is to find out how to develop interactive media for better speaking skill of senior high school students. The research was conducted by using Research and Development (R&D). The subject of this research was 2016/2017 students of the eleventh grade of Class XI IPA4 in SMAN 1 Batang Kuis. The number of the students was 30 students. The data of this study was collected by using need analysis questionnaire and experts’ judgment. Need analysis questionnaire was calculated by using percentage to get the information of students’ need before developing interactive media. Experts’ judgment was calculated by using likert data, mean and criteria interval of expert judgment to know the validity of interactive media which has been developed. After the data analyzed, it was found that the experts’ judgment result was 4.80 which had a very good criteria interval. The result of the research find that interactive media is a very good to be used in teaching speaking skill.

The objectives of this study were to find out the types of lexical ambiguity and the most dominant type of lexical ambiguity used in analytical exposition texts in English Today 2 and Advanced Learning English 2 textbooks. This study was conducted by using descriptive qualitative method. The research was mainly focused on the four types of lexical ambiguity proposed by Saeed, such as homonymy, polysemy, synonymy and antonymy. In carrying out this study, the data were taken from analytical exposition texts in reading materials and exercise material from the two English textbooks which contained of ambiguous words. The result of the study indicated the numbers of lexical ambiguity were 46 words within homonymy (34,8%), polysemy (28,2%), synonymy (19,6%), and antonymy (17,4%).

<div>We present here an interdisciplinary workshop on the subject of biomolecules offered to undergraduate and high-school students with the aim of boosting their interest toward all areas of science contributing to the study of life. The workshop involves Mathematics, Physics, Chemistry, Computer Science and Biology. Based on our own areas of research, molecular modeling is chosen as central axis as it involves all disciplines. In order to provide a strong biological motivation for the study of the dynamics of biomolecules, the theme of the workshop is the origin of life. </div><div>All sessions are built around active pedagogies, including games, and a final poster presentation.</div>
