Pengaruh Strategi Index Card Match Siswa Kelas IV terhadap Hasil Belajar IPA di Sekolah Dasar

The purpose of this study was to determine the effect of the Index Card Match strategy on the science learning outcomes of students in class IV at SDN 101930 Perbaungan. The population studied in this study was the entire class A and B IV at SDN 101930 Perbaungan. The population in the study amounted to 44 students. As for the results of the study, namely the science learning outcomes of students who were taught with conventional learning in class IV students of SDN 101930 Perbaungan got an average score of 45.59. The learning outcomes of the control class students who were taught conventionally were categorized as adequate. Student learning outcomes in science taught using the Index Card Match Strategy for fourth graders at SDN 101930 Perbaungan got an average score of 71.5. Student learning outcomes are much better after the learning process using the Index Card Match strategy can be said to be categorized as good. The influence of the Index Card Match Strategy on the Science Learning Outcomes of Class IV SDN 101930 Perbaungan, can affect the science learning outcomes, this is evidenced by the results of the hypothesis where the level of a = 0.05 tcount ttable is 5.246 0.297 ttable, Ho is rejected, thus it can be concluded that there is a significant effect

Sikap terhadap Sains Siswa dalam Pembelajaran IPA Fisika melalui Penerapan Strategi Index Card Match pada Materi Kalor di Kelas VII 4 SMPN 20 Pekanbaru

The aim of this research was to determine the creasing of students\u27 attitudes toward science Physics in class VII4 SMPN 20 Pekanbaru by implementing in learning Index Card Match strategy in heat subject. The research subjects were students of class VII4 totalling 39 people consisting of 15 male students and 24 female students. Data collection instruments in this research a question of students attitudes towards science consisting of 24 items. Analysis of the data in this research is descriptive analysis to see changes in students attitudes toward science and use the gain. From the analysis of the data showed an increase in students attitudes towards science has increased by an average of 0.31. Thus, it can be concluded that the implementation of physics learning using the Index Card Match strategy can improve students\u27s attitudes toward science in class VII4 SMP 20 Pekanbaru

Corruption: Measuring the Unmeasurable

While the strategy of measuring and quantifying has been extremely successful, and valuable in the progress of science, it does not follow that it is universally useful. We argue that attempts to measure corruption can be counterproductive in several different ways. Qualitative and action oriented approaches may prove more valuable. A political economy explanation of why extremely distorted and biased measures of corruption continue to be used is also offered.Corruption, measurement, quantitative imperative, corruption perception index

Homogeneous optical cloak constructed with uniform layered structures

The prospect of rendering objects invisible has intrigued researchers for centuries. Transformation optics based invisibility cloak design is now bringing this goal from science fictions to reality and has already been demonstrated experimentally in microwave and optical frequencies. However, the majority of the invisibility cloaks reported so far have a spatially varying refractive index which requires complicated design processes. Besides, the size of the hidden object is usually small relative to that of the cloak device. Here we report the experimental realization of a homogenous invisibility cloak with a uniform silicon grating structure. The design strategy eliminates the need for spatial variation of the material index, and in terms of size it allows for a very large obstacle/cloak ratio. A broadband invisibility behavior has been verified at near-infrared frequencies, opening up new oppotunities for using uniform layered medium to realize invisibility at any frequency ranges, where high-quality dielectrics are available

Cost-effectiveness analysis of the management of distal ureteral stones in children

Objective To determine the most cost-effective approach to the management of distal ureteral stones in children given the potential for recurrent renal colic during a trial of passage versus potential stent discomfort and complications of ureteroscopy. Methods We developed a decision tree to project costs and clinical outcomes associated with observation, medical explusive therapy (MET), and ureteroscopy for the management of an index patient with a 4mm distal ureteral stone. We determined which strategy would be least costly and offer the most pain-free days within 30 days of diagnosis. We performed a one-way sensitivity analysis on the probability of successful stone passage with MET. We obtained probabilities from the literature and costs from the 2016 Pediatric Health Information System Database. Results Ureteroscopywas the costliest strategy but maximized the number of pain-free days within 30 days of diagnosis ($5,282/29 pain-free days). MET was less costly than ureteroscopybut also less effective ($615/21.8 pain-free days). Observation cost more than MET and was also less effective ($2,139/15.5 pain-free days). The one-way sensitivity analysis on the probability of successful stone passage with MET demonstrated that ureteroscopyalways has the highest net monetary benefits value and is therefore the recommended strategy given a fixed WTP. Discussion Using a rigorous decision-science approach, we found that ureteroscopy is the recommended strategy in children with small distal ureteral stones. Although it cost more than MET, it resulted in more pain-free days in the first 30 days following diagnosis given the faster resolution of the stone episode

Research Paper: School Of Teacher Training and Education, Muhammadiyah University of Surakarta. March, 2016. This research is aiming at (1) differences in the use of mind mapping’s strategy with index card match’s strategy auctioned in learning outcome of natural science at the 4th grade students of SDIT Nur Hidayah Surakarta 2015/2016 academic year, (2) a better implementation in learning outcome of natural science between mind maping’s strategy with index card match’s strategy at the 4th grade students of SDIT Nur Hidayah Surakarta 2015/2016 academic year. This research is experiment quantitative. The Subject of this research is all students at 4th grade of SDIT Nur Hidayah Surakarta 2015/2016 academic year. The tehnique of collecting data is test and documentation. Test instruments include test the validity and reliability testing. The tehnique of analizing data is t-test which doing pre-requisite test like homegenity test and normality test first. Based on the data analysis about 5% degree’s significance the result shows ttest > ttable is 2,0722 > 1,993 which the average of the learning outcome at 4th grade C is higher than the learning outcome at 4th grade D, is 85,1 > 82,5. The conclusion is (1)there are differences in leraning outcome of natural science using mind mapping’s strategy and index card match’s strategy auctioned in learning outcome of natural science at the 4th grade students of SDIT Nur Hidayah Surakarta 2015/2016 academic year. (2) mind mapping’s strategy is bigger than index card match’s strategy auctioned in learning outcome of natural science at the 4th grade students of SDIT Nur Hidayah Surakarta 2015/2016 academic year.
