Flexibility is an essential quality for an athlete, which is why a high level of flexibility is required to increase efficiency and economy of movement, which interests all sports disciplines.The purpose of this scientific approach is to show that the development of static flexibility specific to foot techniques in karate, for practitioners between the ages of 14 and 18, is not done at random. The drive systems, applied within the programme proposed in this study for the development of flexibility, are subject to anatomically determined laws of motion, are functional and succeed in a methodical sequence.The experiment performed on karate practitioners - Shotokan emphasizes the importance of developing specific mobility which will allow them to execute foot techniques at a higher level and achieve outstanding performance.The application of the tests and the implementation of carefully selected drive systems that contribute to the development of mobility specific to karate techniques substantiates the working hypothesis and validates through its results the correctness of the experimental operation.

This research is motivated by the desire to make a change to conventional and monotonous ways of learning by providing variations in science learning for students, where so far learning has been fixated on old media that are not relevant to the demands of innovation in education namely skill-based learning in the 21st century and the industrial revolution 4.0. The purpose of this study was to determine the effect of the use of video animation based on a scientific approach to the high-level thinking skills of students. The sample in this study were students majoring in Primary teacher education programs in science education, which were determined by cluster random sampling techniques. The study used an experimental methodology with a pretest-posttest control design. (3) T-test results from the results of the analysis of high-level thinking skills scores of students showed a significance value of 0.002 <0.05, proving that the final ability of the experimental class group was significantly higher than the control class. This indicates that the use of scientific animated video approaches influences students' high-level thinking skills.

A glimpse of what is being taught Islam shows how much this religion intersect with science and education, for example, paragraphs 4 and 5 of Surah Al-Alaq, God Almighty, as a primary teacher, taught man what he did not know by means of a pen, « (الذی علم بالقلم (4) علم الانسان ما لم یعلم (5), when the Koran highlighted the importance of the pen as a tool for learning and spreading knowledge to swear to the pen, «ن والقلم وما یسطرون» ie "Noon. I swear by the pen and what the angels write. ", then all substance is solving educational problems existing in Islamic Education. Solve the problem of how to use the various disciplines in the face of an integrative way of life seemed quite handed over to the students to develop competencies naturally. The purpose of this study were: 1) Describe the effect of learning with a scientific approach to achievement motivation in class VII SMP Negeri 1 Gresik Wringinanom. 2) Describe the effect of learning with a scientific approach to learning achievement in Grade VII SMP Negeri 1 Gresik Wringinanom. From the analysis can be summarized as follows: 1) From the analysis it is known that the scientific approach to learning with an effect on achievement motivation in class VII SMP Negeri 1 Gresik Wringinanom value obtained Fhitung 15 641 (significance F = 0.000). So Fhitung> Ftabel (15 641> 1.60) or Sig F <5% (0.000 <0.05). This means that learning with the scientific approach effect on achievement motivation in class VII SMP Negeri 1 Gresik Wringinanom. then the null hypothesis (H0) is rejected and Working Hypothesis (H1) is accepted. 2) From the analysis show that the scientific approach to learning with an effect on learning achievement in grade VII SMP Negeri 1 Gresik Wringinanom value obtained Fhitung 2,924 (significance F = 0.009). So F count> F table (2,924> 1,60) or Sig F <5% (0.009 <0.05).

The aim of this study was to investigate the reliability of a newly developed long distance (LD) simulated triathlon for testing performance and physiological changes in LD triathletes. Ten trained LD triathletes (mean ± standard deviation: age 34.1 ± 5.0 years, body mass 69.07 ± 13.89 kg) completed two separate trials of a simulated LD triathlon consisting of a 1500 m swim, a 60 minute cycle at 60% of power at VO2max and a 20 minute run at 70% of velocity at VO2max. Performance (time, pace, power and rating of perceived exertion) and physiological (economy of movement (oxygen cost and energy consumption), blood lactate and heart rate)variables were measured throughout the simulated LD triathlon. Coefficient of variations (CV %) and intra class correlation coefficients (ICC) were calculated to determine reliability. The current study displayed a high level of reliability, with moderate to excellent ICC measurements for performance and physiological variables (ICC 0.62 – 0.99). All physiological variables, except blood lactate, demonstrated CV values < 10%. In conclusion, the newly developed LD simulated triathlon has a high level of task representation for LD triathletes and can accurately assess performance changes in a research setting.

Advisory committees are part and parcel of policy-making in every government agency. Their input is used at many levels, ranging from high level strategic initiatives and planning to very specific input into narrowly defined decisions. This chapter describes an operational overview of the different approaches used by science agencies in the United States and documents the heterogeneous way in which they are used. It suggests that some of the principles that motivated the establishment of advisory committees are not always fully served in practice. It also finds that that the financial structure and incentives of some entities, might usefully be reviewed. The chapter concludes by observing that the structure of committees might be improved by developing a more scientific approach to their constitution.

Learning by using scientific approach is a process of learning that is designed that make the students construct a concept actively, role or princip trough observation step (to identify or to find a problem), stated a problem, propose hypothesis, collecting data by using variety technic, analyze data, getting conclusion, and communicate the concept that find. Therefore, in  the learning process that hoped to stimulate the students in searching the source by an observation, not only  know by the teacher.The scientific approach role in learning process by skill process like observation, classification, assessment, explain, and making conclusion. In doing that process, the students need a helping from teacher. But the helping  must less because the students’ class is in high level.
