Online Tests in the Trend of Education 4.0: An Empirical Study in Mathematics at High Schools of Can Tho City

In the trend of Education 4.0, the assessment of learning results through online tests is increasingly widespread and important because of its usability and mobility. In addition, it is also adaptable in the volatile situations of today's society such as natural disasters, epidemics, war, etc. The paper presents the results of an empirical study in Mathematics at high schools in Can Tho city on the comparison of outcomes between online tests and paper tests. The initial statistical analysis results show that the evaluation of learning results by online tests has high consensus among the experimental group. Furthermore, the advantages and suggestions for improvement are also pointed out and discussed in this work.

PRELIMINARY STATISTICAL ANALYSIS OF THE PROJECTION OF THE VELOCITY OF THE HYDROGEN MOLECULE USING A NOMOGRAM

This article provides an initial statistical analysis of the projection of the velocity of the hydrogen molecule. Checked for normal distribution according to signs of conformity. In it, Kolmagorov's sign, 𝒳2 (xi - squared) sign, 𝜔 2 - sign and other signs were checked for normalcy. We examined the normality of the general set related to the projection of the velocity of the hydrogen molecule in 7 different ways, and in all cases concluded that the 𝐻𝑜 hypothesis was correct.

The Relationship Between Academic Trait Boredom, Learning Approach and University Achievement

This study explored factors that influence academic achievement and hence, future career prospects. The relationships between the factors, academic trait boredom, approach to learning and academic achievement were examined using data collected from university students at a small English university and from their student records. The initial statistical analysis revealed significant effects of gender on learning approach and two of the three academic trait boredom subscales. Female students proved to be less prone to academic trait boredom than their male counterparts. A model was then developed that showed how a student’s choice of learning approach was influenced by academic trait boredom and impinged on academic achievement. This modelling also confirmed that students who are more prone to academic trait boredom are also more likely to adopt a surface approach to learning rather than a deep or strategic one. The results of this investigation have implications for students, lecturers, course designers and learning support staff both here in this one location as well as elsewhere across the higher education sector.

A case study in text mining: Textual analysis of the Territorial Papers

The Territorial Papers of the United States are a valuable and underused resource containing almost 10,000 documents written between 1789 and 1848 about the formation of new sovereign states from US territory. These communications between the federal government and frontier settlers comprise the actual discourse of the nation’s expansion over six decades. Digitizing the Territorial Papers permits the possibility of analyzing the entire corpus globally. Text mining and topic modeling methods give us a lens on the language patterns through which new state governments and the expanding nation were formed. An initial statistical analysis of the textual information provides a visualization of content, helps discern how ideals about governance emerged, and lays the foundation for developing more sophisticated hypotheses and theoretical constructs.

Effectiveness of a New Fluoride Varnish for Caries Prevention In Pre-School Children

Objective: To investigate the effectiveness of a new fluoride varnish (Clinpro White Varnish, 3M Espe, Seefeld, Germany) with regard to the caries incidence within a 2-year period. Study design: A non-randomized sample of 400 children from the Kyffhäuser district (Thuringia, Germany) was divided into a fluoride group (FG, biannual application of fluoride varnish) and control group (CG, no intervention). (Non-)cavitated caries lesions were recorded using World Health Organization (WHO) and Universal Visual Scoring System (UniViSS) criteria. Parents were given questionnaires to gather information about their socio-economic status (SES). Non-parametric methods and binomial logistic regression were used for data analysis. Results: There was a significant increase in caries incidence in both groups. The number of non-cavitated carious lesions was significantly lower in the FG (mean 2.2; sd 2.3) compared with the CG (mean 2.9; sd 1.9). Initial statistical analysis revealed that fluoride varnish might prevent non-cavitated carious lesions. When including SES as a confounder into regression model, potential preventive effect was lost. Conclusions: This study underlines the importance of the multi-factorial etiology of caries and illustrates that the effectiveness of biannual fluoride varnish application was evident in non-cavitated carious lesions only.

Characteristics of Teachers Nominated for an Accelerated Principal Preparation Program

This article reports the initial evaluation results of a new accelerated, job-embedded principal preparation program funded by a Race to the Top Grant (U.S. Department of Education, 2012a) in Florida. Descriptive statistics, t-tests, and chi-square analyses were used to describe the characteristics of a group of potential applicants nominated to the program by their principals. Demographic and education-related variables for the group were compared to a group of self-selected students enrolled in an existing educational leadership master’s program at the same public university. Initial statistical analysis revealed that more than two-thirds of the nominated teachers belonged to a minority group and had not majored in education as undergraduates. These findings have immediate implications for this new program and for research related to the identification of potential future educational leaders.
