(2010) Thesis Strata 1 Program Faculty of Teacher Training and Educational Pancasakti University Tegal. Keyword : Quantum Teaching Methods, achievement of learning English vocabulary. The objective of the research is to know whether the quantum teching method is effective to improve the students English vocabulary achievement of the eight grade student of SMP Negeri 6 Tegal in academic year 2009/2010. Hypothesis of this is that the Quantum teaching method is effective to improve the students English vocabulary achievement of the eight grade student of SMP Negeri 6 Tegal in academic year 2009/2010 (Ho), the quantum teching methods gives positive effect on achievement in learning english vocabulary of the eight grade students of SMP Negeri 6 Tegal inacademic year 2009/2010 (Ha) The population is the whole eight grade students of SMP Negeri 6 Tegal in academic year 2009/2010. the number of the population is 256 students. The random sampling technique is used to take the sample there are 60 students as the sample they are divided into two groups each group has 30 members. The first group (the experiment group) consist of the students who are taught by using quantum teaching methods and the other group (control group) consist of the students who are taught without using quantum teaching methods.
