Social Issue

...ASSIGNMENT 4: Final paper Investigate a Social Issue By June 07th , 2014 SOC 100 Instructor: Professor NAZER In recent years, the relationship between crime and economy crises has been highly studied by economies and has sparked up interest among members of the general public, the media, policy makers, and criminal justice practitioners. Although there are many conflicting ideas on how the economy downturn affects crime rates, it is reasonable to study how crime rates have varied in the past and recent years. Taking a closer look at the current economy trend in the United States, both federal and state budgets have been affected as well as individuals. Many people have been laid off their jobs because the state cannot allocate money for them to be paid. Hence, many such people look for other means to raise money for survival including property theft and other related crimes. It is therefore convenient to say that more people are willing to commit crime in a declining economy so as to meet their daily needs, though it could be a difficult hypothesis to test. Bad economics leads to property theft and robberies as criminals steal items they cannot afford. Since 2008, there has been an increase recession in the United States as said by data from police records. However, the FBI in 2010 release records of a drop in violent crimes but not property theft and robberies. This can be seen on the media reports and even major adverts on the streets such as bus stops where......

...I. PENDAHULUAN A. Pengertian Kegiatan menganalisis butir soal merupakan suatu kegiatan yang harus dilakukan guru untuk meningkatkan mutu soal yang telah ditulis. Kegiatan ini merupakan proses pengumpulan, peringkasan, dan penggunaan informasi dari jawaban siswa untuk membuat keputusan tentang setiap penilaian (Nitko, 1996: 308). Tujuan penelaahan adalah untuk mengkaji dan menelaah setiap butir soal agar diperoleh soal yang bermutu sebelum soal digunakan. Di samping itu, tujuan analisis butir soal juga untuk membantu meningkatkan tes melalui revisi atau membuang soal yang tidak efektif, serta untuk mengetahui informasi diagnostik pada siswa apakah mereka sudah/belum memahami materi yang telah diajarkan (Aiken, 1994: 63). Soal yang bermutu adalah soal yang dapat memberikan informasi setepat-tepatnya sesuai dengan tujuannya di antaranya dapat menentukan peserta didik mana yang sudah atau belum menguasai materi yang diajarkan guru. Dalam melaksanakan analisis butir soal, para penulis soal dapat menganalisis secara kualitatif, dalam kaitan dengan isi dan bentuknya, dan kuantitatif dalam kaitan dengan ciri-ciri statistiknya (Anastasi dan Urbina, 1997: 172) atau prosedur peningkatan secara judgment dan prosedur peningkatan secara empirik (Popham, 1995: 195).
