SkyApp: a tablet-based e-learning design tool for mathematics teachers to cater for learning diversity

Session: Effect of gamesTheme: Engaging Learners: Games and Flipped LearningLearning diversity is one of the most challenging difficulties encountered by teachers in primary and secondary schools. This project aims at building a design tool for teachers of Mathematics to develop tablet-based e-learning activities and apply different pedagogical actions based on the results of learning analytics. With the analysis of fine grained learners’ behaviors in previous activities, such as the handwriting of calculation in solving multi-step questions, number of attempts in answering each question, answering sequence and thinking time, the design tool will ...postprin

Exploring Characteristics of Fine-Grained Behaviors of Learning Mathematics in Tablet-Based E-Learning Activities

Attributes of teaching and learning contexts provide rich information about how students participate in learning activities. By tracking and analyzing snapshots of these attributes captured continuously throughout the duration of the learning activities, teachers can identify individual students who need special attention and apply different pedagogical actions to them. This paper describes the results of the work-in-progress study in exploring characteristics of fine-grained behaviors of learning mathematics in tablet-based e-learning activities. An experimental platform called SkyApp is built. Through SkyApp, teachers can create e-learning activities and track learning records of students after the delivery of the activities. SkyApp supports capturing, storing and analyzing of fine-grained behaviors of students. Pilot tests have been done in two primary schools for eight months. The review of the tests demonstrates the potential in performing learning analytics. By applying clustering algorithms on multiple learning metrics of marks, time and number of attempts for students in solving mathematics questions, classification of students by learning characteristics of performance and engagement can be formulated.

Behavioural and educational outcomes following extremely preterm birth : current controversies and future directions

As a consequence of improved survival rates for extremely preterm (EP; <28 weeks of gestation) births, there is a growing body of evidence detailing the impact of extreme prematurity on outcomes throughout childhood and adolescence. Historically, attention first focused on documenting rates of sensory impairments and severe neurodevelopmental disabilities. However, over recent years, there has been growing interest in the impact of EP birth on long term mental health and educational outcomes. In this chapter we review literature relating to the impact of EP birth on attention, social and emotional problems, psychiatric disorders and educational outcomes. We also outline current controversies in the field. In particular, we present emergent research exploring developmental trajectories to determine whether the sequelae associated with EP birth represent a developmental delay or persistent deficit, and we consider what approaches to intervention may be most fruitful in improving behavioural and educational outcomes in this population

Protection of cigarette smoke–induced up-regulation of neutrophil elastase by Chinese green tea in rat lung

Introduction: Chronic obstructive pulmonary disease (COPD) is a progressively destructive airway disease mainly caused by smoking. Protease/anti-protease imbalance is hypothesised in the pathogenesis of COPD. Many studies have shown that the activities of proteases overwhelmed anti-proteases, causing lung destruction. Neutrophil elastase (NE) is one such protease released by neutrophil degranulation. This study aimed to investigate whether cigarette smoke (CS) exposure would up-regulate NE in bronchial secretions and whether Chinese green tea consumption would control the NE level/activity in the secretions. Methods: Sprague-Dawley rats were divided into four groups, ie sham air, 4% CS, 2% Lung Chen tea plus sham air or 4% CS. Exposure to sham air or 4% CS was performed for 1 hour/day for 56 days in ventilated smoking chambers. Rat lung tissues and bronchoalveolar lavage fluid (BALF) were obtained from rats sacrificed 24 hours after last CS exposure. Activity and amount of NE were determined by activity assay and ELISA analysis respectively. Results: NE activity was higher in BALF than in lung homogenates. There was a significant increase for NE activity in both lung homogenates (29.37±6.26 nM and 1.29±1.22 nM for CS-exposed and sham-air rats respectively; P<0.001) and BALF (43.47±3.15 nM and undetectable level for CS-exposed and sham-air rats respectively; P<0.001). The total amount of NE protein was also increased in BALF after CS exposure. The elevated CS-induced NE activity was prevented by green tea consumption (6.34±5.00 nM and 26.33±1.39 nM for lung homogenates and BALF respectively; P<0.001). Conclusion: These preliminary data suggest that Chinese green tea might have the ability to suppress CS-induced upregulation of NE activity and protein in lung. Further studies will be needed to elucidate the mechanism by which green tea regulates bronchial NE level in lung injury.
