New Breakthroughs and Innovation Modes in English Education in Post-pandemic Era

Abstract

The outbreak of COVID-19 has brought drastic changes to English teaching as it has shifted from the offline mode before the pandemic to the online mode during the pandemic. However, in the post-pandemic era, there are still many problems in the effective implementation of the process of English teaching, leading to the inability of achieving better results in the quality and efficiency of English teaching and effective cultivation of students’ practical application ability. In recent years, English speaking has attracted the attention of experts and scholars. Therefore, this study constructs an interactive English-speaking practice scene based on a virtual character. A dual-modality emotion recognition method is proposed that mainly recognizes and analyzes facial expressions and physiological signals of students and the virtual character in each scene. Thereafter, the system adjusts the difficulty of the conversation according to the current state of students, toward making the conversation more conducive to the students’ understanding and gradually improving their English-speaking ability. The simulation compares nine facial expressions based on the eNTERFACE05 and CAS-PEAL datasets, which shows that the emotion recognition method proposed in this manuscript can effectively recognize students’ emotions in interactive English-speaking practice and reduce the recognition time to a great extent. The recognition accuracy of the nine facial expressions was close to 90% for the dual-modality emotion recognition method in the eNTERFACE05 dataset, and the recognition accuracy of the dual-modality emotion recognition method was significantly improved with an average improvement of approximately 5%.

Technology in the educational processes of basic education in Peru

“…Basic education in Peru before, during, and after the pandemic was not prepared for online teaching as other countries had to learn on the fly. The study by Shen and Guo [20] in times of the COVID-19 pandemic has brought about drastic changes in teaching as it has moved to online mode during the pandemic. However, there are many problems in the effective implementation of the teaching process, leading to the inability to achieve better results in the quality and efficiency of teaching and effective learning of students' practical application ability.…”

Enhancing Supply Chain Efficiency: A Two-Stage Model for Evaluating Multiple Sourcing and Extra Procurement Strategy Optimization

“…The COVID-19 pandemic has forced the industry to change the conventional practices, requiring innovative practices for any kind of industry fields. For example, tourism (Sousa et al [18] and Sousa et al [19]), business management (Illiashenko et al [20]), or education sector (Shen and Guo [21]) have searched for novel breakthroughs to overcome pandemic situations. For the case of supply chain management, Ali et al [22] has thoroughly reviewed the main drivers for Internet of Things (IoT) adoption in the post-pandemic situations.…”

Duet This: Storytelling Through Social Media Video for Teaching English

“…In the post-pandemic era, the demands of teaching and learning have been translated into the needs of students to creatively engage in a digital environment and to prepare students to communicate in an increasingly digital mode of communication (Muftah, 2022;Shen & Guo, 2022). In line with this, a growing body of literature also shows that social media has been used to assist students with flipped learning, a learning style where teachers facilitate and guide students to produce learning content (Han, 2022;Fan, 2022).…”
