The purpose of this study was to Meta-analyze the empirical evidence of the effectiveness of ICTs assisted teaching on preschool children's mathematical achievement. A systematic search of English-writing, peer-reviewed, and randomized controlled studies was conducted. There were 19 studies in which 3,900 participants met the study selection criteria. The results showed that ICTs had a positive and medium effect on young children's mathematics achievement (SMD=0.673), especially on reasoning (SMD=0.642) and numeracy (SMD=0.641) achievement. Under different moderating variables, such as ICTs devices type and experiment period, the effect of ICTs on preschoolers' mathematical achievement was different. Touch screen ICTs devices (SMD=0.834) and experimental periods of less than 4 weeks (SMD=0.769) had high effect levels. According to different mathematics teaching content, flexibly choose and use ICTs devices, and adjust the teaching period of ICTs using to improve the effect of mathematics teaching and children's mathematics achievement.

Background: The 2030 agenda for sustainable development proposed global equitable quality education and lifelong learning opportunities for all children. The quality of early childhood care and education (ECCE) programs helps shape children’s minds, attitudes and behaviors, and has short and long-term effects on a child, a family and a country. In Malaysia, the government has formulated some policies and laws to protect children’s rights. However, ECCE is facing some challenges. The purpose of this study is to investigate parents’ perceptions of the quality of ECCE programs implemented by Malaysian government. Methods: A mixed method was used to collect data on parents’ perceptions of ECCE policies in selected states in Malaysia. The questionnaires, (P1/POL) from the research project “Development of a Comprehensive and Integrated Model of Quality Malaysian ECCE”, were distributed among 629 respondents who have a child in a preschool, and 22 participants were randomly selected to take part in five focus group interviews Results: The key findings of the study revealed 68% parents were not familiar with ECCE Malaysian government policy, however 84.3% stressed it is important for the government to educate them about ECCE. Thus findings indicated that the majority of parents lack awareness of the ECCE policies and quality of early childhood care and education programs related to the policies remain the issue. While interviewing the focus group ,most of them were not aware of ECCE and pointed out parents are stressing children’s academic learning in particular preschools. Conclusions: It is concluded that parents’ awareness regarding the ECCE program must be part of the policies and needs to improve. It is recommended that the government of Malaysia should supply more information on ECCE policies to parents and focus on policy implementation. Moreover, the quality of ECCE programs should be improved based on the parents’ perceptions.

The present work aims to study the influence of virtual reality (VR) technology on the teaching and curriculum of preschool physical education in colleges and universities and establish a virtual teaching model suitable for the college teaching system. The classroom teaching situation of using VR technology in physical training of preschool education major direction in colleges and universities is investigated using the questionnaire survey and teaching experiment. Firstly, the feasibility of applying VR technology to teaching is proved by analyzing the relevant education theories. Secondly, the experimental research method is designed to verify the application effect of VR technology in teaching behavior. Finally, the collected data is sorted out to judge the method’s feasibility. The experimental results demonstrate that 88.0% of the respondents are curious about the application of VR, and 88.6% of the respondents can accept the application of VR in sports dance teaching. Besides, 89.1% claimed that VR technology could enhance students’ understanding of knowledge, and 93.0% thought that VR applications would not interfere with teachers’ explanations. In addition, 80.0% thought that virtual teaching could stimulate students’ interest in learning, 75.0% said that VR application could attract students’ attention, and 63.0% believed that VR application could improve learning efficiency. The preliminary investigation suggests that introducing VR technology can reduce the work intensity of teachers, and the students participating in the survey are optimistic about the application of VR technology in preschool physical education. The formal test based on a t-test indicates that the average score of the experimental group is 3.18 points higher than that of the control group, and there are significant differences in technology between the control group and the experimental group. VR technology can improve students’ technical level, enhance self-confidence, and improve students’ grades. To sum up, this study provides a reference for developing virtual teaching mode and applying VR technology to physical education.

Cardiothoracic intensive care unit (CICU) nurses have shared the role and responsibility for ventilator-weaning to expedite decision-making in patient care. However, the actions taken are based on individual's unstructured training experience as there is no clinical practice guideline (CPG) for nurses in Malaysia. Hence, this study aims to design a CPG for the process of weaning from mechanical ventilation (MV) for a structured nursing training in a CICU at the National Heart Institute (Institut Jantung Negara, IJN) Malaysia. The Fuzzy Delphi Method (FDM) was employed to seek consensus among a panel of 30 experts in cardiac clinical practice on the guidelines. First, five experts were interviewed and their responses were transcribed and analyzed to develop the items for a FDM questionnaire. The questionnaire, comprising of 73 items, was distributed to the panel and their responses were analyzed for consensus on the design of the CPG. The findings suggested that the requirements expected for the nurses include: (a) the ability to interpret arterial blood gases, (b) knowledge and skills on the basics of mechanical ventilation, and (c) having a minimum 1-year working experience in the ICU. On the other hand, the CPG should mainly focus on developing an ability to identify criteria of patient eligible for weaning from MV. The learning content should focus on: (a) developing the understanding and reasoning for weaning and extubating and (b) technique/algorithm for extubating and weaning. Also, the experts agreed that the log book/competency book should be used for evaluation of the program. The CPG for structured nursing training at IJN in the context of the study is important for developing the professionalism of CICU nurses in IJN and could be used for training nurses in other CICUs, so that decision for ventilator-weaning from postcardiac surgery could be expedited.

Surface discharges are precursors to flashover. To pre-empt the occurrence of flashover incidents, utility companies need to regularly monitor the condition of line insulators. Recent studies have shown that monitoring of UV signals emitted by surface discharges of insulators is a promising technique. In this work, the UV signals’ time and frequency components of a set of contaminated and field-aged insulator under varying contamination levels and degrees of ageing were studied. Experimental result shows that a strong correlation exists between the discharge intensity levels under varying contamination levels and degree of ageing. As the contamination level increases, the discharge level of the insulator samples also intensifies, resulting in the increase of total harmonic distortion and fundamental frequencies. Total harmonic distortion and fundamental frequencies of the UV signals were employed to develop a technique based on artificial neural networks (ANNs) to classify the flashover prediction based on the discharge intensity levels of the insulator samples. The results of the ANN simulation showed 87% accuracy in the performance index. This study illustrates that the UV pulse detection method is a potential tool to monitor insulator surface conditions during service.
