A1 اعطية، دعاء راشد. A2 الثلاب، سعيد حسين علي A2 الظفيري، محمد إبراهيم AB The goal of current research is to identify the impact of the seventh learning cycle in : 1) acquire chemical concepts to the students of the scientific fifth grade in chemistry. 2) Development tendency among scientific fifth grade students about chemistry. The experimental design with partial precision was chosen for two equal groups one of them is experimental and the other is control. The sample of research was chosen from (Al-Farook secondary school for girls) randomly (by lot way) from the research community, which is represented by the diurnal governmental preparatory and secondary schools in the city center of Holly Karbala government. The students of scientific fifth grade of school year (2015-2016) were 104 students distributed into three groups are (A, B, C). Group B was chosen randomly to be experimental group and same way C was control group, where the No. of research samples was 69 students and the actual number was 34 students for experimental group who were studied according to seventh learning cycle and 35 student were the control group who was studied according to the usual way without exclusion any student statistically from the two groups, since there is no failed student and the total number of the two groups was 69 students. The researcher equalized statistically between the two groups included the following parameters (age counted in months, previous tendency test, students marks in chemistry in first course, the summation of all examined materials in first course and the education gaining of parents. The research tools, the researcher adopted to choose the main concepts which are 20 concepts to prepare the chemistry concepts acquisition test. Where three items were given for each concept according to the three cognitive processes (definition, distinguishing, and application); therefore, the No. of items of test was 60 items in a kind of multiple choices with four options. The second tool was tendency development scale test, where the researcher adopted to build tendency scale consisting of 32 items included two detective items and each item has three option for answering. The researcher has conducted a previous and subsequent test for the tendency to describe the difference among marks which represent the magnitude of developing the tendency towards chemistry by students. The experiment was applied in the second half of 2015-2016 school year and started on Monday (15/2/2015) and finished on Monday (24/4/2015) which it is lasting full course in fact four classes weekly each group. After experiment had been finished a test was applied on two group research students and marks were taken out for data analysis. After data analysis, the researcher found statistically that good results appeared for the experimental group who studied according to seventh learning cycle comparing to control group who studied according to usual method in concepts acquisition and tendency scale tests towards chemistry. According to research result, the researcher recommended the necessity of seventh learning cycle in chemistry teaching for scientific fifth grade because of their positive impact to acquire the chemistry concepts and developing the tendency. Besides that, the researcher suggests conducting an analogous study to show the impact of seventh learning cycle in other parameters for other study stages.
