6. Raising the Quality of Teaching in Public Schools of Pakistan: A Three Dimensional Analysis for Capacity Development of In-Service Teachers in Instructional Planning and Strategies

Author

Rizwan, Sidra and Khan, Rehana Masrur

Abstract

In order to prepare the upcoming generation to handle the sophisticated skills required to contribute to a knowledge-based society, the teachers need to be more successful with the learners having varied needs and learning styles. Development of teachers on the basis of professional standards is part of a broader movement for the assurance of quality in various fields of human life. The standard and quality of education is directly related with the quality and standard of teachers. The standard of effective and efficient teaching comprises of three dimensions which are further divided into multiple indicators of knowledge and understanding of the content, disposition of the teachers and the skill they portray in teaching. The important question here is that: 'What are the needs of in-service teachers in planning out the instructions and selecting appropriate strategies?' A definite and workable approach to answer the question has been done through three dimensional gap analyses while assigning arbitrary scores and five levels to each indicator of all three dimensions. The mixed method and methodological triangulation approach was used for the collection of data. Three dimensional indicator wise analyses revealed the difference between existing levels and desired levels of many indicators of instructional planning and strategies. On the basis of the findings remedial areas have been identified for necessary actions. This definitely will raise the quality of learning as well.

23. A Facile Approach for the Synthesis of Diverse Heteroaryl C-Glycosides as Potential Phosphorylase Inhibitors.

Abstract

Here, an efficient, one-pot and facile synthesis of nitrogen-containing heteroaryl C-glycosides is described. Protected 1-formyl sugars were condensed with various benzene derivatives to afford the desired sugar-linked benzimidazoles, benzoxazoles and benzthiazoles. In contrast to their O-analogues, these C-glycosides are less vulnerable to metabolic processing, which has led to significant interest in their viability as drug candidates and inhibitors of carbohydrate processing enzymes. Detailed spectroscopic analyses of all synthesized derivatives have been performed using 1H and 13C experimental techniques. Quantum chemical calculations including molecular orbital analysis have been performed by density functional theory using B3LYB functional and 6-3//G+(d,p) basis set. Molecular orbital calculations have provided detailed description of the orbitals including spatial characteristics and nodal patterns. Global and local reactivity descriptors have been computed to theoretically predict the reactive sites within the molecule and the reaction pathway. [ABSTRACT FROM AUTHOR]

Abstract

Purpose: To develop a deep learning (DL) system that can detect referable diabetic retinopathy (RDR) and vision-threatening diabetic retinopathy (VTDR) from images obtained on ultra-widefield scanning laser ophthalmoscope (UWF-SLO). Design: Observational, cross-sectional study. Participants: A total of 9392 UWF-SLO images of 1903 eyes from 1022 subjects with diabetes from Hong Kong, the United Kingdom, India, and Argentina. Methods: All images were labeled according to the presence or absence of RDR and the presence or absence of VTDR. Labeling was performed by retina specialists from fundus examination, according to the International Clinical Diabetic Retinopathy Disease Severity Scale. Three convolutional neural networks (ResNet50) were trained with a transfer-learning procedure for assessing gradability and identifying VTDR and RDR. External validation was performed on 4 datasets spanning different geographical regions. Main Outcome Measures: Area under the receiver operating characteristic curve (AUROC); area under the precision-recall curve (AUPRC); sensitivity, specificity, and accuracy of the DL system in gradability assessment; and detection of RDR and VTDR. Results: For gradability assessment, the system achieved an AUROC of 0.923 (95% confidence interval [CI], 0.892–0.947), sensitivity of 86.5% (95% CI, 77.6–92.8), and specificity of 82.1% (95% CI, 77.3–86.2) for the primary validation dataset, and >0.82 AUROCs, >79.6% sensitivity, and >70.4% specificity for the geographical external validation datasets. For detecting RDR and VTDR, the AUROCs were 0.981 (95% CI, 0.977–0.984) and 0.966 (95% CI, 0.961–0.971), with sensitivities of 94.9% (95% CI, 92.3–97.9) and 87.2% (95% CI, 81.5–91.6), specificities of 95.1% (95% CI, 90.6–97.9) and 95.8% (95% CI, 93.3–97.6), and positive predictive values (PPVs) of 98.0% (95% CI, 96.1–99.0) and 91.1% (95% CI, 86.3–94.3) for the primary validation dataset, respectively. The AUROCs and accuracies for detecting both RDR and VT
