The goal of current researcher to know the impact of strategic Jigsaw in the collection of hypertext and geographic operations of science students at the preparatory stage And that by checking the following 1.There is no difference statistically significant at the significance level 0.05 between the experimental group students who were studying strategy Jigsaw and between the control group students who studied in the usual way traditional degrees in the average achievement in the subject of geographical 2.There is no difference statistically significant at the significance level 0.05 between the experimental group students who were studying strategy Jigsaw and between the control group students who studied in the usual way traditional average test scores in science processes in the subject of geographical The sample consisted of 50 students distributed between the experimental group and a control group of 25 students in each group the equal students the sample in the following variables chronological age previous achievement in the subject of geographical historical experience intelligence the academic level of the parents. The researcher prepared to tools the first achievement test items objective than types consists of 50 choice of multi with four alternatives and the second test of science operations be one of the 30 paragraphs in both objective type multiple-test with four alternatives , it was verified validity and reliability of the validity and reliability of the validity and reliability of both instruments Experience has been in tilted in the first semester of the academic year 2015-2016 and lasted 13 weeks she studied at the experimental group under a strategy Jigsaw , in the same period the control group was taught the traditional way and used appropriate statistical methods , and results 1.There are difference statistically significant at the level of significance 0,05 between the average level students the experimental group who studied under a strategy to Jigsaw and average al jmuah officer who studied in the traditional way in achievement test, And in favor of the experimental group . 2.There are differences statically significant at the level of significance 0,05 between the average level students the experimental group who studied under a strategy to jigsaw and average grades al jmuah officer who studied in the traditional test operations in science , and in favor of the experimental group. 3.The size of the impact on the achievement jigsaw strategy and operations of a large flag. In light of the findings of the current research was directed taking strategy jigsaw in teaching geographical preparatory phase for its impact on the achievement of science and operations , And rehabilitation of teachers how to use geographic jigsaw strategy and the development of science prosses they have in teaching

In this study, we investigate the behavior of the estimated spectral density function of stationary time series in the case of missing values, which are generated by the second order Autoregressive (AR (2)) model, when the error term for the AR(2) model has many of continuous distributions. The Classical and Lomb periodograms used to study the behavior of the estimated spectral density function by using the simulation.

To ascertain the stability or instability of time series, three versions of the model proposed by Dickie-Voller were used in this paper. The aim of this study is to explain the extent of the impact of some economic variables such as the supply of money, gross domestic product, national income, after reaching the stability of these variables. The results show that the variable money supply, the GDP variable, and the exchange rate variable were all stable at the level of the first difference in the time series. This means that the series is an integrated first-class series. Hence, the gross fixed capital formation variable, the variable national income, and the variable interest rate
