In addition to increased learning completeness, the average student learning outcomes in mathematics also increased. There is a change in the involvement of students to discuss and cooperate with fellow friends in terms of solving problems given by the teacher. Changes in the activity of students to take part in learning mathematics. The seriousness of students in participating in learning has also increased. The activeness of students in answering oral questions has also increased. This is indicated by the increasing number of students who give correct answers. the activeness of students in completing homework is increasing. This is indicated by the increasing frequency of students completing homework on time. The activeness of students to appear in front of the class solving problems on the board also increased. Students begin to believe in themselves and have the ability to solve the problems given. Based on observation, the teacher has a problem where the students are very familiar with the conventional way, the teacher explains in front of the class while students listen, Building a conducive classroom atmosphere by involving students to be more active sometimes inviting a commotion in the classroom where students initially play more than learn. Building a sense of responsibility to students also becomes difficult because students' demands actually become reversed because the teacher explains a little subject matter and students are directed to further develop material insights through discussion activities and so on. The application of the 2013 curriculum also requires students to understand the implementation of the value of the knowledge acquired so that a variety of practical activities are needed as a tangible form of the implementation of students' mathematical knowledge

This paper describes an innovative, three-day, turbomachinery research project for Japanese and British high-school students. The project is structured using modern teaching theories which encourage student curiosity and creativity. The experience develops team-work and communication, and helps to break-down cultural and linguistic barriers between students from different countries and backgrounds. The approach provides a framework for other hands-on research projects which aim to inspire young students to undertake a career in engineering. The project is part of the Clifton Scientific Trust’s annual UK-Japan Young Scientist Workshop Programme. The work focuses on compressor design for jet engines and gas turbines. It includes lectures introducing students to turbomachinery concepts, a computational design study of a compressor blade section, experimental tests with a low-speed cascade and tutorials in data analysis and aerodynamic theory. The project also makes use of 3D printing technology, so that students go through the full engineering design process, from theory, through design, to practical experimental testing. Alongside the academic aims, students learn what it is like to study engineering at university, discover how to work effectively in a multinational team, and experience a real engineering problem. Despite a lack of background in fluid dynamics and the limited time available, the lab work and end of project presentation show how far young students can be stretched when they are motivated by an interesting problem.

Taxicab Geometry

The urban world in which many of us live does not lend itself to the metric of Euclidean geometry. Assuming that the avenues are perpendicular to the streets in a city, the distance from “fifth and fifty-first” to “seventh and thirty-fourth” is not the familiar Euclidean distance found by applying the Pythagorean theorem. The distance must instead be measured in blocks from fifth to seventh avenues and then from fifty-first to thirty-fourth streets. This taxicab metric, one of several me tries used in mathematics (Eisenberg and Khabbaz 1992), is practical for many applications and helps students pursue interesting investigations while deepening their understanding of familiar topics.

The increased demand for energy, climate change, and energy security concerns has driven the research interest for the development of alternative fuel from plant origin. Biodiesel derived from plant oils, which include edible and non-edible oil have gained interest for the last two decades as alternative for diesel around the world. The purpose of this study was to determine the perceptions of high school students in Jakarta on the regarding renewable biodiesel. The study conducted a survey among twelve-grade. High school students studying in private schools in easten Jakarta  in order toexplore their perceptions of biodiesel  production from non eedible oil and edible oil  for heat and power. A total of 20 item questionnaires were administeredto a total of  185 students in twelve grades. In addition, three open-endedquestions were asked of the students in order to determine their level of knowledge regarding biodiesel, and power stations. The study data were analyzed using the SPSS statistical package program. The study results revealed that, thestudents were of the perception  that biodiesel  use wouldreduce global warming, and that renewable energy sources areenvironment-friendly, non toxic and renewable.In addition, thestudents generally knew about biodiesel  sources and their importance, although they lacked knowledge about certain aspects of biodiesel.The study recommends energy and educational policy makers to increase awareness of  non edible and edible oil baseed bioenergy production among young students. In this respect, schools, parents, and media can also play an important role to engage young students in bioenergy related discussions.

The purpose of this analysis is to show that strong connections might exist between the teaching of mathematics, science and art. This is due to the particular geometrical configurations behind several paintings and other artistic creations. Therefore, the knowledge of this connection might be of help for the students to guess that mathematics and science also have possible applications to art. This is particularly relevant for the high schools of art. Since too often, mathematics is taught in high schools without any relevant link to reality, this can be one of the reasons of students’ disaffection for this subject. In this analysis, a teaching experiment developed by the author in an Italian (Udine) high school of art is proposed. In particular, Escher’s periodic drawings, and the ornamental motifs that characterize many products in reality, offer an interesting opportunity to make high school students understand the relevance of mathematics and especially of geometry in art. The discovery of mathematical laws, that derive from crystallography, behind Escher’s drawings should persuade students that such an artistry is reachable only by means of mathematical knowledge. In what follows the main features of the outlined didactical proposal are presented and discussed. Keywords: Escher, periodic drawings, mathematics and art, mathematics teaching, cristallography
