Corrective Feedback and Repair Strategies in Meaning-focused Language Classroom

The practice of corrective feedback in communicative language classroom has become a debate among applied linguists. Some consider it obstructs students' fluent speech and some assert it is vital to show students their linguistic gaps. This study aims to describe the practice of oral corrective feedback in meaning-focused instruction specifically to answer the questions 1) what is to correct, 2) how it is corrected, and 3) how repair is constructed. The data are in the forms of teacher's and students' utterances obtained through video recording during meaning-focused instruction in a secondary school. The result shows that in meaning-focused instruction, the ESL teacher mainly corrects semantic errors and among six types of corrective feedback (explicit correction, recast, clarification request, metalinguistic feedback, elicitation, and repetition), the teacher mostly uses elicitation and recast while the repair strategies that occur in this class takes the pattern of other initiation-self repair. So, it can be concluded that in a meaning-focused instruction the teacher does not relatively interrupt the students' fluent speech and that the communicative activity is maintained. And with self-repair, students notice their linguistic gaps. Therefore corrective feedback is still worth practicing in meaning-focused language classrooms

ANALISIS RASIO KEUANGAN UNTUK MEMPREDIKSI KONDISI FINANCIAL DISTRESS PERUSAHAAN MANUFAKTUR YANG TERDAFTAR DI BEI

Financial  distress  precedes  bankruptcy.  Most  financial  distress  models actually rely on bankruptcy data, which is easier to obtain. The purpose of this research to examine financial ratios that predict financial distress condition of a firm. The sample of this research consist of 14 distress firm and 79 non-distress firms, chosen by purposive sampling. The statistic method which is used to test on the research hypothesis  is logistic regresion. The results show that the liquidity ratio (current assets/current liabilities) and a leverage ratio  (current leabilities/total  asset)  is  a  significant  variable  to  determine  of  financial  distress firms.  When  profitability  ratio  (net  income/net  sales)  and  price  earning  ratio (market  price  per  share/earnings  per  share)  are  not  significant  variables  to determine of financial distress

THE IMPLEMENTATION OF SYNCHRONOUS AND ASYNCHRONOUS E- LANGUAGE LEARNING IN EFL SETTING: A CASE STUDY

Teaching and learning process since the pandemic time has shifted away from the traditional face to face classroom into online distance learning, and this will be undergo in the post pandemic. This case study aimed to investigate the effectiveness use of the combined modes of synchronous and asynchronous in e- language learning for university students. While both types of that learning approach have its importance in different scenario. The research questions to be answered in the study was how the adoption of synchronous (discussion activity platform) and asynchronous (learning content platform) would be more effective in e- language learning. 55 university participants from the second semester of English Department who joined the online creative writing class in synchronous and asynchronous language learning activity received the survey questionnaire as the sampling of the collected data. The data from the interview was also obtained to get the learners insights regarding the course experiences.The results showed that the applying of the combination approach in online learning has been greatly effective in helping the learners in terms of the community interaction and  material engagement. Moreover, the learners’ response about the using blended mode of synchronous and asynchronous for their learning is very positive. Some suggestions to enfold the problems over the online learning  are also provided

Analisis Pengaruh Saturasi Oksigen terhadap outcome pasien stroke iskemik fase akut di RSUD Dr. Moewardi

There are controversies about the influence of oxygen saturation level for stroke patients as a predictor of acute phase stroke outcome. Oxygen saturation was selected as the examination because it is an easy, rapid, and economical by using only pulse oxymeter. A good oxygen saturation level is critical in oxygen supply in acute phase of ischaemic stroke. The use of oxygen saturation at hospital admission is still controversial in predicting outcome or neurologic improvement because prior studies showed opposite results. The researcher in this study would like to investigate the influence of oxygen saturation at hospital admission to the outcome of ischemic stroke during acute phase so that it may give clues as a predictor of stroke outcome. This is a cross sectional study, using a purposive sampling method. The subjects were acute ischemic stroke patients in the inward section of the neurology department of Meowardi General Hospital. The minimal sample was 60. The level of stroke severity is measured with NIHSS. Analysis for statistic was using linear regression with confidence levelof 95%, significant if p < 0,05. Results showed that there is a correlation of oxygen level saturation at hospital admission to NIHSS score on the first day but has no correlation to the outcome of acute infarct stroke patients in RSUD Dr. Moewardi General Hospital. Analysis was then continued using fisher test and a significant correlation was found between oxygen saturation at hospital admission to stroke outcome. Conclusion: There is an influence of oxygen saturation at hospital admission to NIHSS score at day-1 and no influence to NIHSS at day-7. There is a significant correlation between oxygen saturation at hospital admission to acute stroke aoutcome Keyword: Acute Ischemic Stroke, Oxygen Saturation, NIHS
