Douglas Hofstadter's "Metamagical Themas: Questing for the Essence of Mind and Pattern" is not the Hofstadter book people probably expected to eventually turn up in a Passages column, to be honest. And I do not want to disparage his most famous work; I read Godel, Escher, Bach: an Eternal Golden Braid (GEB) one Christmas vacation, I believe when I was in the eighth grade, and it was a revelatory and enchanting experience, with a profound impact on the course of my future life. But everyone knows about that book, and has an opinion on it; I think it's a literary masterpiece and even when it gets something wrong, it does so in an interesting way.

This study aims to know the influence of active learning model Course Review Horay to biology learning outcomes at eighth grade students of SMP Negeri 10 Batam academic year 2013/2014. This research design is  randomized experiment using posttest only control-group design. The study population is all the eighth grade students of  SMP Negeri 10 Batam with reached population consist of 7 classes. The sampling technique using a simple random sampling. Samples were selected class VIII5 as control class and VIII8 as experiment class. The instrument  that use in this research is the form of the test. Requirement have been in the form of normality and homogeneity test, which showed that normal and homogeneous data. Technique of data analysis conducted by the t test. The result analysis of data using the t test showed the tvalue 3.01 and ttable is 2.00 (tvalue > ttable). The results showed that the active learning result model Course Review Horay give effect to increase student learning outcomes from the average of the experimental class 82,57 and control class 76,04. Thus, the hypothesis put forward acceptable significance level (α = 0.05). Thus, it can be concluded that the using of active learning model Course Review Horay influential on learning outcomes of biology at eighth grade students of SMP Negeri 10 Batam. Keywords: Course Review Horay, Biology Learning Outcomes.

This study aims to determine the effect of cooperative learning models and studentlearning styles on the results of learning Social Sciences. Conventional learning models thatrely on reading books, multiplying practice exercises, teacher explanations in the classroom,students are expected to be more diligent in practicing questions suspected of influencingsocial studies learning outcomes. Conventional models are considered to be less than optimal,because basically students will easily feel bored because they have to open sheets per sheetby understanding the contents of the book and listening to the teacher's explanation in frontof the class verbally.This study uses an experimental comparison method containing activities planned and carriedout by researchers, 2x2 factorial design in this study to find out whether there are differencesin social studies learning outcomes between students who obtain learning with cooperativelearning models and students who obtain conventional learning. The population in this studywere all eighth grade students of Al-Kamil Middle School Islamic Boarding School in CianjurRegency, West Java. Affordable population there are eighth grade students of Al-KamilMiddle School Islamic Boarding School District. Cianjur numbered 120 students. The resultsof this study indicate that there is an interaction effect between learning models and learningstyles on the results of social studies learning at Al-Kamil Middle School Islamic BoardingSchool. Learning outcomes of students who have independent learning styles and followcooperative learning models are higher than students' learning outcomes that followconventional learning models. Likewise the learning outcomes of students who havedependent learning styles and follow cooperative learning models are higher than students'learning outcomes that follow conventional learning models

The Hipparcos mission demonstrated the efficiency of space astrometry (in terms of number of objects, accuracy, and uniformity of results) and the fact that a relatively small instrument can have a very large scientific potential in the area of astrometry. However, Hipparcos could probe less than 0.1 per cent of the volume of the Galaxy by direct distance measurements. Using a larger instrument and more efficient detectors, it is now technically feasible to increase the efficiency of a space astrometry mission by several orders of magnitude, thus encompassing a large part of the Galaxy within its horizon for accurate determination of parallaxes and transverse velocities. Such a mission will have immediate and profound impact in the areas of the physics and evolution of individual stars and of the Galaxy as a whole.
