Analysis of Text-Based Grammar Teaching Method on the Language Proficiency and Grammar Accuracy of ESL Learners in China

This research paper explores the impact of text-based grammar teaching method on the language proficiency and grammar accuracy of English language learners in China. Two research questions were addressed: Research Question 1: Does text-based grammar teaching method improve language proficiency, in terms of writing, speaking, reading, and listening, of English language learners in China? Research Question 2: Does text-based grammar teaching method improve the grammar accuracy of English language learners in China? Through a mixed research approach, including a survey of 100 respondents, this study provides comprehensive insights into the effectiveness of text-based grammar teaching method. The findings reveal that text-based grammar teaching method significantly enhances language proficiency. Notably, improvements were most pronounced in writing (90%) and reading (93%) skills. While the impact on speaking (73%) and listening (76%) skills showed variability, this study suggests that a more balanced approach, incorporating increased speaking practice and listening activities, may yield more consistent results. Furthermore, the study demonstrates that text-based grammar teaching method has a profound impact on grammar accuracy, with 94% of respondents reporting improvements. This method also facilitates the ease of understanding grammar rules, as indicated by 96% of respondents finding it helpful in grasping grammar rules more easily. In conclusion, this research underscores the potential of text-based grammar teaching method as a valuable tool in language education, particularly for enhancing writing, reading, and grammar accuracy. The study highlights the importance of addressing individual differences and tailoring instruction to improve speaking and listening skills. These findings contribute to a deeper understanding of the role of text-based grammar teaching in language education and provide valuable insights for educators seeking effective pedagogical approaches in diverse learning environments. &nbsp

Boosting Paired Comparison methodology in measuring visual discomfort of 3DTV: performances of three di erent designs

International audienceThe pair comparison method is often recommended in subjective experiments because of the reliability of the obtained results. However, a drawback of this method is that the number of comparisons increases exponentially with the number of stimuli, which limits its usability for a large number of stimuli. Several design methods that aim to reduce the number of comparisons were proposed in the literature. However, their performances in the context of 3DTV should be evaluated carefully due to the fact that the results obtained from a paired comparison experiment in 3DTV may be in uenced by two important factors. One is the observation error from observer's attentiveness, in particular inverting the vote. The second factor concerns the dependence on the context in which the evaluation takes place. In this study, three design methods, namely Full Paired Comparison method (FPC), Square Design method (SD) and the Adaptive Square Design method (ASD) were evaluated by subjective visual discomfort experiment in 3DTV. The results from the FPC method were considered as the ground truth. Comparing with the ground truth, the ASD method provided the most accurate results with a given number of trials. It also showed the highest robustness against observation errors and interdependence of comparisons. Due to the e ciency of the ASD method, paired comparison experiments become feasible with a reasonably large number of stimuli for measuring 3DTV visual discomfort

Influence of Demographics and Buying Capacity on Consumer Buying Behaviour During the COVID-19 Pandemic in Dumaguete City, Philippines

The study looks into how the buying behaviour of the residents of Dumaguete City, in regards to demographics and consumer buying capacity, is influenced by the COVID-19 pandemic. A descriptive research method was used by the researcher, and the testing of the null hypothesis, at 0.05 level of significance, was done through the Chi-Square test of independence. There were 316 respondents, living, working, and studying in Dumaguete City, who participated in this study. The results show that majority of the respondents are experiencing varying levels of financial pressure during the COVID-19 pandemic, which directly influences the buying behaviour of most people. The test result indicated that there is a significant relationship between consumer buying behaviour during the COVID-19 pandemic and consumer buying capacity. Furthermore, the results also show that gender, education, and occupation directly influence consumer buying behaviour during the COVID-19 pandemic. Lastly, age and family size do not constitute a significant relationship with consumer buying behaviour during the COVID-19 pandemic

Numerical simulation of diffusion MRI signals using an adaptive time-stepping method

International audienceThe effect on the MRI signal of water diffusion in biological tissues in the presence of applied magnetic field gradient pulses can be modelled by a multiple compartment Bloch-Torrey partial differential equation. We present a method for the numerical solution of this equation by coupling a standard Cartesian spatial discretization with an adaptive time discretization. The time discretization is done using the explicit Runge-Kutta-Chebyshev method, which is more efficient than the forward Euler time discretization for diffusive-type problems. We use this approach to simulate the diffusion MRI signal from the extra-cylindrical compartment in a tissue model of the brain gray matter consisting of cylindrical and spherical cells and illustrate the effect of cell membrane permeability
