Words and Bots: An Empirical Experiment Vocabulary Mastery with Robotics in Young Children

This study aims to determine the impact of educational robot on increasing English vocabulary as a foreign language. Pre-experimental research design was conducted with 35 first grade junior high school students as sample. The pre-post English vocabulary test was given to the sample and the research were done in eight meetings. In the control class there was no action treatment and did not use robots in learning but in the treatment class, researchers used educational robots, namely the Evoce robot in learning. From the comparison between the two classes both the control class and the treatment class from the pre and post English vocabulary tests, the result finding showed in the t-test score based on the value of df = 35-1 = 34 at a significant level of 5%, a ttable of 1.0691 is obtained and at a significant level of 1%, a ttable of 2.441 is obtained. With a tcount of 9.899, which means that it is greater than ttable at a significance level of 5% and 1%, (1.0691 < 9.899 > 2.441) then Ho is rejected and Ha is accepted. In summary, the Evoce robot has given contribution in young learners’ English vocabulary. It recommended that the educational robot may become one of alternative media to be used for recent days for English vocabulary class.

Evaluation of the reciprocal teaching style in tennis

The purpose of this study was to evaluate the Reciprocal Teaching Style (hereinafter R.T.S.), in basic strokes of tennis, such as forehand, backhand and service, and at the same time to investigate whether it affects the development of motor skills. The first part of the research consisted of 102 children aged 14-15 years with no previous experience in Tennis. There were held 12 lessons for the first two strokes (forehand and backhand) and then 8 lessons for the service to students in 6 classes of third -grade Junior High School students in 2 different schools. The sample members were divided into two groups (experimental and control), and the data were processed in the statistical program IBM SPSS 24 using the t-test for independent samples before and after the intervention with a significance level of (p <.05). The survey showed that the performance of the participants was improved in tennis in the forehand, backhand and service in both teams (especially in the E.G.), after finding a statistically significant difference in the scores (increasing the mean of consecutive strokes and accuracy). In the second part of the research, the sample consisted of 408 students aged 12-15, 204 students in High Schools of the Municipalities of Tanagra and Chalkida, as well as 204 from tennis clubs of the Municipalities of Larissa, Chalkida and Thebes. A detailed plan of one hour reciprocal teaching was applied to the 3 main aforementioned tennis strokes and at the end the participants were given as a measuring tool, anonymously and confidentially the questionnaire of Intrinsic Motivation Inventory (IMI) by McAuley et al. (1989). Data processing in IBM SPSS 24 via one-way variance analysis (One-Way Anova) gave the results: There is a statistically significant difference between the first-grade and second-grade High School classes in the effort which is due to a systematic factor and the pleasure, the perceived ability, the pressure, the attitude / opinion towards tennis, the intention to try tennis and the physical activity are influenced by the highest level of education completed by the father.
