How can an automated essay scoring (AES) program, which provides feedback for essays, be a formative tool for improving ESL writing? In spite of the increasing demands for English writing proficiency, English writing instruction has not been effective for teaching and learning because of a lack of timely and accurate feedback. In this context, AES as a possible solution has been gaining the attention of educators and scholars in ESL/EFL writing education because it can provide consistent and prompt feedback for student writers. This experimental study examined the impact of different types of feedback for a college ESL writing program using the Criterion AES system. The results reveal the positive impact of AES in a college-level ESL course and differences between the teacher's feedback and the AES feedback. The findings suggest that AES can be effectively integrated into ESL writing instruction as a formative assessment tool.

Purpose : The purpose of present study was to determine effects of a visual feedback training on balance ability in poststroke hemiparetic subjects. Methods : Fourteen chronic stroke patients participated. Participants were randomly divided into either visual feedback training group(7 experimental group, 7 control group). All of participated were inpatients at local rehabilitation center and had been receiving a traditional rehabilitation program, five days a week. Exprimental group have additionally undergone for four weeks, three days a week, the visual feedback training but control group was not received any additional program except the traditional rehabilitation program. The Berg Balance Scale(BBS), the FICSIT-4, the MTD-balance system to measure a balance ability were carried out twice before and after training. Results : After participation in the program, subjects of visual feedback training demonstrated a significant improvement in the scores of the BBS, the FICSIT-4, the MTD-Balance system. The control group had no change on the any tests. After the training, the result to improve significantly in visual feedback training group compared to post-test of control group were the score of BBS and the FICSIT-4 and the MTD-Balance system. Conclusions : The present study suggests that the visual feedback training program may become a useful strategy for enhancing balance ability in the rehabilitation of stroke patiens.

Objective: This study is to investigate the effect of real-time feedback from the therapist on posture, muscle strength, pain of subjects with forward head posture based on a non-face-to-face complex exercise program. Design: Two-group pretest-posttest design. Methods: Thirty healthy men and women in their twenties with forward head posture with a Craniovertebral angle of 52° or less were targeted, the final selection was made as 15 experimental groups who performed the non-face-to-face intervention program while receiving real-time feedback and 15 control subjects who performed the non-face-to-face intervention program without providing feedback. Six of them were eliminated, and a total of 24 were conducted as subjects. All exercise groups performed an exercise program three times a week, 30 minutes each, for a total of two weeks. Before and after exercise, Craniovertebral angle (CVA), CranioRotation angle (CRA), muscle strength, and tenderness threshold were evaluated. Results: Significant differences were shown in both groups in CVA, and tenderness threshold before and after exercise (p<0.05), and CRA, the left middle trapezius muscle strength, only in the experimental group (p<0.05). In the comparison of theamount of change between exercise groups, the group that received feedback on CVA, CRA and tenderness threshold showed a significant change than the group without feedback (p<0.05). Conclusions: As a result of this study, it can be seen that the therapist's real-time feedback is more effective in improving the forward head posture. This requires feedback from the therapist on posture correction during non-face-to-face exercise intervention.

Purpose: Hemiplegic patients usually present with difficulties in maintaining their balance. Balance retraining is a major component of a rehabilitation program for patients with neurological impairments. This study compared the effects of prorpioceptive exercise and visual feedback program on the limits of stability (LOS) in chronic hemiplegia patients. Methods: Thirty subjects (mean age $57.0{\pm}9.8$) were recruited. The subjects were divided into a proprioceptive group and a visual group. The subjects for the proprioceptive group participated in the proprioceptive exercise program for 4 weeks, and the visual group were treated with visual feedback training using a Balance Master. Results: At the 4 week follow-up test, the LOS in the proprioceptive group improved significantly in all directions (p<0.05). However, improvement was only observed in the forward direction in the visual feedback group. Therefore, the proprioceptive control approach improves the LOS in chronic hemiplegia patients. Conclusion: These results suggest that compared with physical therapy alone using a proprioceptive control approach to hemiplegia, there was no additional benefit of visual feedback training, such as Balance Master, when administrated in combination with other physical therapy interventions.

이 연구는 20대 여대생들을 대상으로 세 가지 균형조절 훈련(Aqua, Bio-feedback, Trampolin)이 정적 균형 능력과 시각, 전정각, 고유수용감각 등의 감각요소에 미치는 효과를 비교하기 위해 아쿠아 훈련군(10명), 바이오피드백 훈련군(10명), 트램폴린 훈련군(9명)으로 무작위 할당한 후 각 군별로 주 3회, 회당 30분간의 운동 프로그램을 6주간 진행하면서 3주후, 6주후에 Tetrax portable multiple system을 이용하여 안정성지수를 측정하고, 근전도 중앙주파수값을 이용하여 산출한 근전도 균형점수를 반복측정된 자료의 분산분석 및 Wilcoxon의 부호순위 검정 등을 이용하여 비교 분석한 결과를 종합해 볼 때, 바이오피드백 훈련은 세 가지 감각기능을 고루 향상시키며 아울러 감각기능 간의 협응성 또한 향상시키는 것으로 판단되며, 아쿠아 훈련은 전정기능을 집중적으로 강화시키는 것으로 보인다.

This study aims to investigate the different opinions about feedback given to high level Middle School students about their writing.18 students in the Gifted Program participated in the study. They were divided into three groups through their presurvey answers according to their language learning opportunities and genders. Students language self-assessment was compared with achievement as well. Three times of students' written work were collected. They then received feedback from the teacher and their two peers respectively. With the teachers' and peers' feedback, they completed their final draft. The study then examines how much the students take feedback practically from the different feedback givers. Examples of formative and corrective feedback were arranged to find out the differences in the students practice when giving and taking feedback. These Gifted class students showed that they didn't care much about who gave them the feedback, instead they cared more about how much language competence they presumed the feedback giver had. Implications of the findings are discussed and future study is suggested.

The purpose of the study were to investigate the effect of the neuro-feedback program which improves brain function and stress reduction effect. The research design is one group pretest-posttest survey. 121 nursing students of a college in the Busan region took part in the study. Training involving the neuro-feedback program was conducted twice a week, 30 minutes per session, for a total of 10 weeks. The collected data was encoded and analyzed using SPSS 12.0 Version. The brain function and stress levels of the subjects were analyzed through the before-and-after results of the training were analyzed using a paired t-test. The results of the study showed that the BQ and SQ were enhanced as a result of the neuro-feedback. In particular, there were significant increases in the SRQ, ATQ, ACQ, and EQ of the BQ. SQ is correlated with the prevalence rate and resistance to disease, meaning not only psychological anxiety, uneasiness and excitement, but also physical anxiety and response to disease. Based on the study, by using the neuro-feedback training as a program for stress reduction, it is expected that nursing students will receive less stress from internal and external factors, and their ability to cope with stress will be enhanced.
