Modelling pre-service teachers' perceived usefulness of an ICT-based student-centred learning (SCL) curriculum: a Singapore study

Timothy Teo 서울대학교 교육연구소 2009 Asia Pacific Education Review Vol.10 No.4

The purpose of this study is to examine the factors that influence pre-service teachers' perceived usefulness of an Information and Communication Technology (ICT) course that was conducted using the student-centred learning (SCL) approach. In this study, perceived usefulness was used as the dependent variable and perceived competence, course delivery, facilitating conditions and learning environment as independent variables. The results of this study showed that perceived competence and course delivery have direct effects on pre-service teachers' perceived usefulness of the course, while learning environment and facilitating conditions affect perceived usefulness indirectly. Overall, the results support the hypothesis that the four selected variables in this study affect perceived usefulness and that the resulting model is an adequate fit to the observed relationships among the factors that influenced pre-service teachers' perceived usefulness of an ICT course.

Examining the influence of subjective norm and facilitating conditions on the intention to use technology among pre-service teachers: a structural equation modeling of an extended technology acceptance model

Timothy Teo 서울대학교 교육연구소 2010 Asia Pacific Education Review Vol.11 No.2

This study examined pre-service teachers' self-reported behavioral intentions to use technology. Three hundred and fourteen participants completed a survey questionnaire measuring their responses to six constructs from a research model that extends the technology acceptance model (TAM) by including facilitating conditions and subjective norm. Structural equation modeling was used as the main technique for data analysis. This study contributes to the growing interests in using information science models to explain intention to use technology in educational contexts. The results of this study showed that the TAM constructs were significant in explaining pre-service teachers' intention to use technology. Although facilitating conditions and subjective norm had significant effects on behavioral intention to use technology, they were mediated by attitude toward usage, perceived usefulness, and perceived ease of use. Overall, this study indicated the TAM has sufficient explanatory powers to explain pre-service teachers' intention to use technology in an educational environment.

In the recent decade, Thailand has launched many initiatives to ensure that technology is integrated into the school curriculum. Despite the investment and efforts of the government, few studies have been conducted to examine users’ acceptance of technology. Given that educators are the change agents in many educational initiatives, it is important to gain insights into the factors that influence their uses of technology for teaching and learning. The aim of this study is to survey the level of technology acceptance among pre-service teachers in Thailand. In so doing, the level of technology acceptance among a national sample of 969 pre-service teachers was measured and whether their acceptance was significantly differentiated by gender, age, perceived technology competence, and computer experience was assessed. Using the Technology Acceptance Measure for Pre-service Teachers (Teo in Educ Psychol Meas 70(6):990–1006, 2010a; Multicult Educ Technol J 4(3):163–172, 2010b), the results provided preliminary evidence which suggests that pre-service teachers possess an above-average level of technology acceptance and that computer experience acted as a mediator of technology acceptance. To some degree, this study has contributed to the ensuing debates on technology acceptance in education and offered additional insights into the advancement of technology integration in Asia.

Background: Unstable distal clavicles experience high non-union rates, prompting surgeons to recommend surgery for more predictable outcomes. There is a lack of consensus on the optimal method of surgical fixation, with an array of techniques described in the literature. We describe an alternative method of fixation involving the use of a distal clavicular anatomical locking plate with Fibertape cerclage augmentation in our series of patients. Methods: Nine patients (8 males and 1 female), with a mean age of 36 years, who sustained unstable fracture of the distal clavicle in our institution were treated with our described technique. Postoperative range of motion, functional and pain scores, and time to radiographic union were measured over a mean follow-up period of 10 months. Incidences of postoperative complications were also recorded. Results: At the last patient consult, the mean visual analog scale score was 0.88±0.35, with a mean Disabilities of the Arm, Shoulder, and Hand (DASH) score of 1.46±0.87 and American Shoulder and Elbow Surgeons (ASES) score of 94.1±3.57. The mean range of motion achieved was forward flexion at 173°±10.6°, abduction at 173°±10.6°, and external rotation at 74.4°±10.5°. All patients achieved internal rotation at a vertebral height of at least L2 with radiographical union at a mean of 10 weeks. No removal of implants was required. Conclusions: Our described technique of augmented fixation of the distal clavicle is effective, produces good clinical outcomes, and has minimal complications.

Spinal Stenosis Presenting with Scrotal and Perianal Claudication

Jacob YL Oh,Jun-Hao Tan,Timothy WW Teo,Hwan-Tak Hee 대한척추외과학회 2015 Asian Spine Journal Vol.9 No.1

A 63-year-old gentleman presented with a one-year duration of progressive neurogenic claudication. However, unlike most patients who presents with leg symptoms, his pain was felt in his scrotal and perianal region. This was exacerbated with walking and standing, but he had immediate relief with sitting. An magnetic resonance imaging (MRI) was performed which showed severe central canal stenosis. An L3/4 and L4/5 surgical decompression and a transforaminal lumbar interbody fusion was performed, and the patient made good recovery with immediate resolution of symptoms. Although rare, spinal stenosis should be considered a differential when approaching a patient with perianal and scrotal claudication, even in the absence of leg claudication. An MRI is useful to confirm the diagnosis. This rare symptom may be a sign of severe cauda equina compression and we recommend decompression with predictable good results.

Short-term comparative outcomes between reverse shoulder arthroplasty for shoulder trauma and shoulder arthritis: a Southeast Asian experience

Background: Reverse shoulder arthroplasty (RSA), first introduced as a management option for cuff tear arthropathy, is now an accepted treatment for complex proximal humeral fractures. Few studies have identified whether the outcomes of RSA for shoulder trauma are comparable to those of RSA for shoulder arthritis. Methods: This is a retrospective, single-institution cohort study of all patients who underwent RSA at our institution between January 2013 and December 2019. In total, 49 patients met the inclusion criteria. As outcomes, we evaluated the 1-year American Shoulder and Elbow Surgeons (ASES) and Constant shoulder scores, postoperative shoulder range of motion, intra- and postoperative complications, and cumulative revision rate. The patients were grouped based on preoperative diagnosis to compare postoperative outcomes across two broad groups. Results: The median follow-up period was 32.8 months (interquartile range, 12.6–66.6 months). The 1-year visual analog scale, range of motion, and Constant and ASES functional scores were comparable between RSAs performed to treat shoulder trauma and that performed for arthritis. The overall complication rate was 20.4%, with patients with a preoperative diagnosis of arthritis having significantly more complications than those with a preoperative diagnosis of trauma (34.8% vs. 7.7%). Conclusions: Patients who underwent RSA due to a proximal humeral fracture or dislocation did not fare worse than those who underwent RSA for arthritis at 1 year, in terms of both functional and radiological outcomes.
