Tujuan dari penelitian ini adalah untuk mengetahui pengaruh metode pembelajaran kooperatif Round Robin terhadap prestasi belajar siswa SMA pada mata pelajaran Bahasa Indonesia. Penelitian ini merupakan penelitian eksperimen dengan desain randomized two group design post-test only. Hasil analisis menunjukkan bahwa nilai F sebesar 48,783 dengan taraf signifikansi 0.000 dan nilai t sebesar 6.241 dengan signifikansi 0.000. Dengan demikian dapat disimpulkan bahwa metode pembelajaran kooperatif tipe Round Robin dapat mempengaruhi prestasi be...

Since Edward Leamer's memorable 1983 paper, “Let's Take the Con out of Econometrics,” empirical microeconomics has experienced a credibility revolution. While Leamer's suggested remedy, sensitivity analysis, has played a role in this, we argue that the primary engine driving improvement has been a focus on the quality of empirical research designs. The advantages of a good research design are perhaps most easily apparent in research using random assignment. We begin with an overview of Leamer's 1983 critique and his proposed remedies. We then turn to the key factors we see contributing to improved empirical work, including the availability of more and better data, along with advances in theoretical econometric understanding, but especially the fact that research design has moved front and center in much of empirical micro. We offer a brief digression into macroeconomics and industrial organization, where progress—by our lights—is less dramatic, although there is work...

Exploiting the exogenous variation in childcare costs caused by a Swedish childcare reform, we are able to identify the causal effect of childcare costs on fertility in a context in which childcare enrollment is almost universal, user fees are low, and the labor force participation of mothers is very high. Anticipation of a reduction in childcare costs increased the number

Title. Evaluation of an osteoporosis prevention education programme for young adultsAim.  This paper reports a study exploring the effectiveness of an osteoporosis prevention education programme for young adults.Methods.  A quasi-experimental study was carried out with two groups, using pre-, post- and follow-up measures and was conducted in one integrated services centre during the period July 2005 to November 2005.Results.  The results showed statistically significant increases in the reported follow-up for each outcome: osteoporosis knowledge test scores, osteoporosis health brief scores, and osteoporosis self-efficacy scores, for those in the intervention group compared with those in the control group. On the satisfaction score, most participants in the intervention group rated the nurse's performance in the educational programme positively.Conclusion.  Strategies used in this programme may provide guidance for the design of future programmes.
