Self Efficacy of Pre-Service English Teachers in Using English as a Language Instruction
Authors: Starinne Adria Rosy , Kurniawati Dyah 
Published: October 2019

Field Experience Program or Praktek Pengalaman Lapangan (PPL) are carried out by students to fulfill the requirements for the formation of the education profession. But in the process of PPL, the pre-service English teachers of English Language Education Study Program at the University of PGRI Ronggolawe Tuban often experience problems related to their efficacy when teaching in English as language of instruction.This study aims to determine the efficacy of English Language Education students who run the Field Experience Program (PPL) in using English as the language of instruction, as well as what factors influence their efficacy in using English as the language of instruction. It is a phenomenological qualitative research which the choice of subject or data source was done by purposive sampling which focused on selected informants who were appropriate for in-depth studies (Nana Syaodih, 2007: 101). The subjects are pre-service English teachers who had finished undergoing PPL in the period between November 2017 to January 2018. Data collection techniques used are observation, interviews, and documentation, and using descriptive inductive analysis.The results of this study reveal that self-efficacy of all pre-service English teachers (six students) as subjects in this study in terms of the use of English as the language of instruction during PPL has varied self-efficacy on dimensions of magnitude, strength and generality. Only 1 out of 6 students had negative self-efficacy in all dimensions, and 1 (one) person showed positive self-efficacy in all dimensions; magnitude, strength and generality. While the others vary for all three dimensions. Those six students used both English and Indonesian in teaching English. The reason was because they were not confident (2 people), and for the emphasis on certain material delivered so that it is more easily understood (4 people).This study found that the factors of success experience and psychological factors were the strongest in forming self-efficacy of the 6 PPL pre-service teachers in using English as the language of instruction during field experience program. Furthermore, it is only slightly influenced by other people's success factors and social persuasion. The more experience and the better the psychological condition of students, the more positive their self-efficacy. Two students, namely Mg and Su, have negative self-efficacy due to the lack of teaching experience and poor psychological conditions because they felt uncomfortable and underappreciated in the school where they carried out the field experience program.

OBJECTIVEPhenotypic differences between moyamoya disease (MMD) and moyamoya syndrome (MMS) remain unclear. The purpose of this study was to evaluate whether such differences exist when presentation, procedure-related, and outcome variables are compared quantitatively.METHODSThe study cohort included 185 patients with moyamoya presenting to the Johns Hopkins Medical Institutions between 1994 and 2015. Baseline demographic, angiographic, and clinical characteristics were compared between patients with MMS and MMD, in addition to procedure-related complications and length of stay (LOS) after surgery. Stroke-free survival was compared between both disease variants after diagnosis. Kaplan-Meier analysis and Cox proportional hazards regression were used to compare stroke-free survival between surgically treated and conservatively managed hemispheres in both types of disease, while evaluating interaction between disease variant and management.RESULTSThe cohort consisted of 137 patients with MMD (74%) with a bimodal age distribution and 48 patients with MMS (26%) who were mostly under 18 years of age (75%). Underlying diseases included sickle cell disease (48%), trisomy 21 (12%), neurofibromatosis (23%), and other disorders (17%). Patients with MMS were younger (p < 0.001) and less likely to be female (p = 0.034). Otherwise, baseline characteristics were statistically comparable. The rate of surgical complications was 33% in patients with MMD and 16% in patients with MMS (p = 0.097). Both groups of patients had a similar LOS after surgery (p = 0.823). Survival analysis (n = 330 hemispheres) showed similar stroke-free survival after diagnosis (p = 0.856) and lower stroke hazard in surgically managed patients in both MMD (hazard ratio [HR] 0.29, p = 0.028) and MMS (HR 0.62, p = 0.586). The disease variant (MMD vs MMS) did not affect the relationship between management approach (surgery vs conservative) and stroke hazard (p = 0.787).CONCLUSIONSMMD and MMS have largely comparable clinical and angiographic phenotypes with analogously favorable responses to surgical revascularization.
Rapid-stretch injury to peripheral nerves: implications from an animal model

OBJECTIVERapid-stretch nerve injuries are among the most devastating lesions to peripheral nerves, yielding unsatisfactory functional outcomes. No animal model has yet been developed that uses only stretch injury for investigation of the pathophysiology of clinical traction injuries. The authors’ objective was to define the behavioral and histopathological recovery after graded rapid-stretch nerve injury.METHODSFour groups of male B6.Cg-Tg(Thy1-YFP)HJrs/J mice were tested: sham injury (n = 11); stretch within elastic limits (elastic group, n = 14); stretch beyond elastic limits but before nerve rupture (inelastic group, n = 14); and stretch-ruptured nerves placed in continuity (rupture group, n = 16). Mice were injured at 8 weeks of age, comparable with human late adolescence. Behavioral outcomes were assessed using the sciatic functional index (SFI), tapered-beam dexterity, Von Frey monofilament testing, and the Hargreaves method. Nerve regeneration outcomes were assessed by wet muscle weight and detailed nerve histology after 48 days.RESULTSPost hoc biomechanical assessment of strain and deformation confirmed that the differences between the elastic and inelastic cohorts were statistically significant. After elastic injury, there was a temporary increase in foot faults on the tapered beam (p < 0.01) and mild reduction in monofilament sensitivity, but no meaningful change in SFI, muscle weight, or nerve histology. For inelastic injuries, there was a profound and maintained decrease in SFI (p < 0.001), but recovery of impairment was observed in tapered-beam and monofilament testing by days 15 and 9, respectively. Histologically, axon counts were reduced (p = 0.04), muscle atrophy was present (p < 0.01), and there was moderate neuroma formation on trichrome and immunofluorescent imaging. Stretch-ruptured nerves healed in continuity but without evidence of regeneration. Substantial and continuous impairment was observed in SFI (p < 0.001), tapered beam (p < 0.01), and monofilament (p < 0.01 until day 48). Axon counts (p < 0.001) and muscle weight (p < 0.0001) were significantly reduced, with little evidence of axonal or myelin regeneration concurrent with neuroma formation on immunofluorescent imaging.CONCLUSIONSThe 3 biomechanical grades of rapid-stretch nerve injuries displayed consistent and distinct behavioral and histopathological outcomes. Stretch within elastic limits resembled neurapraxic injuries, whereas injuries beyond elastic limits demonstrated axonotmesis coupled with impoverished regeneration and recovery. Rupture injuries uniquely failed to regenerate, despite physical continuity of the nerve. This is the first experimental evidence to correlate stretch severity with functional and histological outcomes. Future studies should focus on the pathophysiological mechanisms that reduce regenerative capacity after stretch injury.

OBJECTIVEThe object of this study was to evaluate surgical outcomes and prognosis factors in patients with drug-resistant posttraumatic epilepsy (PTE) who had undergone resective surgery.METHODSThe authors retrospectively reviewed the records of all patients with drug-resistant PTE who had undergone resective surgery at Sanbo Brain Hospital, Capital Medical University, in the period from January 2008 to December 2016. All patients had a follow-up period of at least 2 years. Seizure outcomes were evaluated according to the International League Against Epilepsy (ILAE) classification. Patients in ILAE classes 1 and 2 during the last 2 years of follow-up were classified as having a favorable outcome; patients in all other classes were considered to have an unfavorable outcome. Univariate analysis and a multivariate logistic regression model in a backward fashion were used to identify the potential predictors of seizure outcomes.RESULTSAmong 90 patients with a follow-up of 2–10 years (mean ± standard deviation, 5.79 ± 2.84 years), 70% (63 patients) were seizure free, of whom 68.9% (62 patients) had an ILAE class 1 outcome and 1.1% (1 patient) had an ILAE class 2 outcome. Permanent neurological deficits were observed in 10 patients (11.1%). Univariate and multivariate analyses revealed that only the duration of seizures ≤ 8 years was an independent predictor of a favorable seizure outcome (OR 0.34, 95% CI 0.13–0.92).CONCLUSIONSResective surgery is an effective treatment for patients with drug-resistant PTE with an acceptable incidence of complications. The information on prognosis factors suggests that early surgery may offer more benefits to patients with drug-resistant PTE.
