Some of the beginner athletes in UKM of court tennis in UPGRIS conduct swing on the forehand striking in a slightly different way. Some when swinging with fully straight arms, some are slightly bent. The aim of the study is to investigate the differences between elbow extension and elbow flexion toward the accuracy level of forehand striking of court tennist. This research method uses comparative design. The sample of this study is the tennis players of the students in Universitas PGRI Semarang, the total are 7 people. The Hewiit Tennis Achievement Test is used for forehand striking instruments and dartfish software to find out the differences between the elbow movements and the analysis. Independent t-test is used to find out the differences of the striking accuracy result. The results show the significant differencs between elbow extension and elbow flexion with an average score of 22 and 63, with the significance value of a difference of 0.001. The conclusion of this research is that the elbow flexion movement in forwardswing step is better than elbow extension movement.

This study aims to determine the effect of the use of the number card playing method on student motivation and learning outcomes in fraction material in class IV SD NU 03 Nurul Huda Wuluhan Jember. The research method used was a quasi-experimental study with a total of 20 experimental and control class students. Data collection techniques are using pretest and posttest. Analysis of the data used was the T test. The results of the data analysis with the T test at the 95% confidence level showed that the learning outcomes of the experimental class students who used the number card playing method were better than students in the control class who did not use the number card playing method. From the results of the above analysis the researcher draws the conclusion that the learning outcomes of students who use the number card game method program are higher than students who do not use the number card game method. So the number card game method can be used as an alternative learning media that can increase student motivation and learning outcomes.Keywords: Game Method, Number Cards, Learning Outcomes

LANGUAGE NOTE | Document text in Chinese; abstract also in English.The main aim of this study was to investigate the influence on tennis serve performance in terms of with/without audiences and with/without receivers. The subjects were 18 tennis players - 13 from the National College of Physical Education and Sports and 5 from the Army tennis team. They were classified into two main groups: national players (Gl) and non-national players (G2). Successful rate, speed, accurate rate and double-fault of serve were recorded under the circumstances of with/without audiences and with/without receivers. Four different conditions were used: (1) without audiences and without receivers, (2) without audience and with receivers, (3) with audiences and without receivers, and (4) with audiences and with receivers. Independent t-test was used to compare the difference between the groups of Gl and G2 under the four situations whereby α level was set at .05. As a consequence, the results reveal that there was no significant difference between these groups of tennis players under the circumstances of first/second serve successful rate, first/second serve speed, first/second serve accurate rate and double-fault, with/without audiences and with/without receivers. Nevertheless, the non-national players appeared to perform better than the national players under the circumstances of first/second serve successful rate, first/second serve accurate rate and double-fault, with audiences and with receivers.本研究主要是探討國手與非國手在練習發球時，有、無觀眾在場與有、無人接發球對發球表現的影響，以提供國內敎練與選手作為訓練的依據。以13名國立體育學院運動技術系網球隊選手及5名國軍網球隊選手，合計18名男選手為研究對象。共分為國手組及非國手組兩組自願擔任本研究的受試者。記錄這些受試選手在有、無觀眾在場與有、無人接發球四種情境下的發球表現情形(進球率、進球速度、準確率及雙發失誤)。共分四種情境：(1)無觀眾在場、無人接球時。(2)無觀眾在場、有人接發球時。(3)有觀眾在場、無人接發球時。(4)有觀眾在場、有人接發球時。以獨立樣本t考驗來考驗國手組與非國手組在四種不同情境下的發球表現是否有差異。顯著水準設在α = .05。本研究結果發現比較國手與非國手在四種情況下第一與第二發球進球率、第一與第二發球進球速度、第一與第二發球準確率以及雙發失誤的t考驗均未達顯著水準，但國手的表現普遍較非國手來得好。但唯有在「有觀眾在場與有人接發球」情況下，非國手的第一及第二發球進球率、第一及第二發球準確率及雙發失誤較國手有較好的傾向。

The objective of the research is to know whether the aplication of Picture word inductive model improve students’ vocabulary at SMP Negeri 2 Jikumerasa. In this research, the researcher used quantitative research method with pre-Experimental design of the one group pretest and posttest. The sample of the research was 26 students learning at the seventh grade of SMP Negeri 2 Jikumerasa which consist of 7 male students and 19 female students. The data were collected by using 30 items of multiple choices test. The data obtained were analyzed by applying dependent t-test the formula. The result of the analysis show that the average score in posttest X2 = 1818 is greater than score of pretest X1 = 1449, calculation of t-test = 9.39 exceeds the t-table = 1.711 at significant level of = 0.05. Thus the alternative hypothesis (Hα) stating that the use of Picture word inductive model improve students English vocabulary is accepted and the null hypothesis (H0) stating that the Picture Word Inductive Model can not improve students‟ English vocabulary is rejected.
