The two aims of this study were (1) designing and developing an affordable visual reaction system for badminton training that monitors and provides instant feedback on agility; and (2) to measure and improve the footwork and movement of badminton players and output useful reference data. Ten junior high school badminton players were invited to serve as the subjects of this study. They participated in a three-week (nine sessions) training program. Training was primarily in the form of fixed or random footwork drills. Timed tests were performed before and after each session to measure the players’ agility in performing six-point and four-point footwork drills. The results were compared to the training effects calculated using dependent-sample t-tests. In addition, the long-term durability and functionality of the training system were tested. The training system was able to maintain stable and reliable training and evaluation operations for extended periods. Results showed significant improvements in the visual reaction time (p = 0.003) and agility (p = 0.001) of players. The proposed training system is an affordable option for training and monitoring, evaluating, and recording training performance. It can accurately record movement and response times and simulate competitive environments.

Three Components

The responsibility of Islamic education cannot be carried out unilaterally. Ki Hajar Dewantara stated that it requires the cooperation of three components which called as tripusat pendidikan education (center of three in education), they are families, educational institutions, and society. Those three components are one unit and complement each other. This is what happened at MTs Zainur Ridla (Islamic Junior High School Zainur Ridla) and MTs. Bustanul Ulum (Islamic Junior High School Bustanul Ulum), both of them are in Nonggunong District, Sumenep Regency. The findings in this research indicate that student’s guardians in MTs Zainur Ridla and MTs Bustanul Ulum Nonggunong have awareness about the responsibility of Islamic education. Second, all teacher councils in those two Islamic Junior High School stated that educating responsibility was on their control with habituation for their students in the form of reciting Shalawat Nariyah, reciting short surahs before the lesson began, praying before and after the lesson, shaking hands with teacher councils when coming and going home. Third, the participation of the society in realizing the responsibility of Islamic education through the media and the tradition of Kompolan. Fourth, the pattern of cooperation between madrasah (school) and student’s guardians in the form of: Home visits, inviting student’s guardians, forming madrasah supporting body, and report cards. While the pattern of cooperation between madrasah and society is their involvement in PHBI (Commemoration Islamic Feast Day) activities, their involvement in camp activities, their involvement in accepting new students, and their involvement in enforcing the discipline and regulations at madrasah.

The Impact

AbstractIn education, many empirical studies have shown evidence that video games have the potential to improve student learning outcomes, but there is still great controversy in the literature regarding the impact of video game. More evidence is needed to convince educators and researchers regarding the actual value and the efficiency of video game in learning science. The purpose of this study was to examine the use of video game in learning to improve the mastery of concepts about the interaction of living beings and the environment of junior high school students who played the “Selamatkan Dunia Digital!” educational gaming application that has been developed by author in previous studies. This weak experimental study collected pretest and posttest results to determine students' mastery of concepts before and after Intervention. Normalized Gain of the pretest and posttest are assumed to be the effect of the intervention. The results show a low increasing mastery of concept by students who learned by playing game, so this study stated that learning science by using instructional video game media are still not able to facilitate mastery of concept of students.Keywords: interactive media; video game; mastery of conceptsAbstrakDalam dunia pendidikan, banyak penelitian empiris telah berhasil menunjukkan bukti bahwa video game memiliki potensi dalam meningkatkan hasil belajar siswa, tetapi kontroversi besar masih ada pada literatur mengenai pengaruh game yang sebenarnya. Dibutuhkan lebih banyak bukti untuk meyakinkan pendidik dan peneliti mengenai nilai aktual dan efisiensi pembelajaran menggunakan video game. Penelitian ini dilakukan untuk mengetahui penggunaan game dalam pembelajaran untuk meningkatkan penguasaan konsep tentang Interaksi makhluk hidup dengan lingkungan siswa SMP.  Game yang digunakan dalam penelitian ini adalah game yang berjudul “Selamatkan Dunia Digital!” yang telah dikembangkan oleh peneliti pada penelitian sebelumnya. Penelitian ini merupakan penelitian eksperimen semu, dengan desain The one-Group Prettest-Posttest Design untuk memperoleh gambaran penguasaan konsep siswa sebelum dan sesudah perlakuan. Peningkatan nilai pada pretest dan posttest diasumsikan merupakan efek dari perlakuan. Hasil penelitian ini menunjukkan bahwa peningkatan nilai N-gain rata-rata siswa masih dalam kategori rendah, dan pencapaian skor posttest rata-rata siswa juga masih rendah, sehingga dapat disimpulkan bahwa pembelajaran IPA dengan menggunakan media pembelajaran media video game masih belum dapat memfasilitasi penguasaan konsep IPA siswa pada konsep Interaksi Makhluk Hidup dengan Lingkungan.Kata Kunci: media pembelajaran interaktif; video game; penguasaan konsep Permalink/DOI: http://dx.doi.org/10.15408/es.v8i2.1576

The Impact

Learning trends in the 21st-century require students to have the ability to sort appropriate information from certain sources. To do this, students must have critical thinking skills. One of the learning models that can facilitate students to think critically is a guided-inquiry lab. Thus, the purpose of this study was to quantitatively analyze the impact of the implementation of the guided-inquiry lab model on students' critical thinking skills on mechanics material. A pre-experimental method employing one group pretest-posttest only design was applied to obtain students' critical thinking skills data before and after the implementation of the guided-inquiry lab model. A total of 32 students from a junior high school in the city of Karanganyar, Central Java, were involved as the samples in this study. The data obtained were then analyzed using N-gain calculations. Based on the data analysis, there are 81.25% of students have medium creative thinking skills after being taught with a guided-inquiry lab, meaning there is an increase in the average score of students after being taught using a guided-inquiry lab model. It can be concluded that the implementation of the guided-inquiry lab model is effective to improve students' critical thinking skills

Most women who are incarcerated have experienced sexual violence; difficulties adjusting to prison could interfere with women’s ability to benefit from trauma-focused therapy. Here, we explored whether therapeutic benefits of trauma treatment varied as a function of time since incarceration. Women ( N = 128) participated in an 8-week group treatment for sexual violence victimization while incarcerated in a community corrections center for nonviolent offenses. Ninety participants consented to the study and completed self-report questionnaires assessing internalizing symptoms (depression, posttraumatic stress, and shame) before and after treatment. Bivariate correlations revealed a significant negative association between time since incarceration and pretreatment depression but not posttraumatic symptoms or shame. Dependent-sample t tests revealed significant improvements from pretreatment to posttreatment in internalizing symptoms. Longer time since incarceration did not significantly predict internalizing symptoms after controlling for pretreatment symptom severity. Findings suggest trauma-focused treatments can be offered to women shortly after they are incarcerated.

AbstractObjectivesThe improvement in the/reaction time is important, as it is an indicator of cognitive function. Therefore, there is a need, especially for adolescents in the form of techniques or courses that can improve the reaction time. Yoga was found to cause a better improvement in the health of the individuals. The present study intended to show the effects of Bhramari pranayama (Bhr.P) on reaction time in the healthy adolescents.MethodsOf the 730 potential subjects screened, 520 apparently healthy adolescents randomly assigned to either the Bhr.P group (n-260) or control group (n-260). Bhr.P group practiced the bhramari pranayama for 3 days in a week for 6 months. The Auditory Reaction Time (ART) and the Visual Reaction Time (VRT) were assessed before and after Bhr.P pranayama practice.ResultsBhr.P group shows significant shortening of response time in both VRT (from 267.13 ± 52.65 to 249.87 ± 39.41 ms) and ART (from 237.42 ± 48.12 to 227.91 ± 34.60 ms) after 6 months of Bhr.P practice. In control group subjects, no such significant changes were found (p > 0.05).ConclusionsShortening of RT implies an improvement in the information processing and reflexes. This beneficial effect of Bhr.P on reaction time can be used for improving cognitive function in the adolescents for their academic performances.

Purpose. To develop and to test a feedback training system for improvement of tactile perception and coordination of fingers in children and youth with cerebral palsy.Methods. The fingers of 7 probands with cerebral palsy of different types and severity were stimulated using small vibration motors integrated in the fingers of a hand glove. The vibration motors were connected through a microcontroller to a computer and to a response 5-button keyboard. By pressing an appropriate keyboard button, the proband must indicate in which finger the vibration was felt. The number of incorrect responses and the reaction time were measured for every finger. The perception and coordination of fingers were estimated before and after two-week training using both clinical tests and the measurements.Results. Proper functioning of the developed system in persons with cerebral palsy was confirmed. The tactile sensation of fingers was improved in five of seven subjects after two weeks of training. There was no clear tendency towards improvement of selective use of fingers.Conclusion. The designed feedback system could be used to train tactile perception of fingers in children and youth with cerebral palsy. An extensive study is required to confirm these findings.

The purpose of this study was to compare the response times of deaf and normal-hearing individuals to the onset of target events in the visual periphery in distracting and nondistracting conditions. Visual reaction times to peripheral targets placed at 3 eccentricities to the left and right of a center fixation point were measured in prelingually deafened adults and normal-hearing adults. Deaf participants responded more slowly than normal-hearing participants to targets in the near periphery in the nondistracting condition and to targets in the near and distant periphery when distracting stimuli were present. One interpretation of these findings is that deaf individuals may be more deliberate than normal-hearing individuals in responding to near peripheral events and to peripheral events that occur in the presence of distracting stimuli.
