Abstract

Despite growing policy attention to digital education in India under the National Education Policy (NEP) 2020 and numerous government-sponsored training initiatives such as DIKSHA and NISHTHA, the normalisation of Computer-Assisted Language Learning (CALL) in English language classrooms remains limited — particularly in semi-urban and rural districts. This study examines CALL teacher training, its effectiveness, the barriers impeding pedagogical integration, and teachers' preferred professional-development (PD) models among English language teachers in the three North Coastal districts of Andhra Pradesh: Srikakulam, Vizianagaram, and Visakhapatnam.

A concurrent mixed-methods design was adopted. A stratified random sample of 80 English language teachers was drawn from government, aided, and private schools and degree colleges across the three districts. Data were collected via a validated 48-item questionnaire (Cronbach's α = .89) supplemented by semi-structured interviews with 18 purposively selected participants. Descriptive statistics, one-way ANOVA, and reflexive thematic analysis were employed.

Results reveal that while a large majority (75.0%) engage in self-directed online learning, formal pre-service CALL training reaches only 27.5% of participants, and its effectiveness in promoting normalised classroom use is rated low (M = 2.83, SD = 1.16). Four principal barriers — inadequate ICT infrastructure (M = 3.91), curriculum-assessment misalignment (M = 3.74), time scarcity (M = 3.71), and lack of sustained post-training support (M = 3.68) — were identified. Teachers overwhelmingly preferred hands-on practical workshops (83.8%), peer learning communities (75.0%), and school-based mentoring (71.3%). Significant differences in training effectiveness ratings were found across institutional types, F(3, 76) = 6.43, p < .001. The study advocates for a context-sensitive, community-embedded CALL-PD framework anchored in normalisation theory and socio-cultural perspectives on teacher learning.

Abstract

Atherosclerotic disease significantly impacts patients with type 2 diabetes, who often present with recalcitrant peripheral ulcers. The angiosome model of the foot presents an opportunity to perform direct angiosome-targeted endovascular interventions to maximise both wound healing and limb salvage. A systematic review was performed, with 17 studies included in the final review. Below-the-knee endovascular interventions present significant technical challenges, with technical success depending on the length of lesion being treated and the number of angiosomes that require treatment. Wound healing was significantly improved with direct angiosome-targeted angioplasty, as was limb salvage, with a significant increase in survival without major amputation. Indirect angioplasty, where the intervention is applied to collateral vessels to the angiosomes, yielded similar results to direct angiosome-targeted angioplasty. Applying the angiosome model of the foot in direct angiosome-targeted angioplasty improves outcomes for patients with recalcitrant diabetic foot ulcers in terms of primary wound healing, mean time for complete wound healing and major amputation-free survival.
