The teaching content and process of Petrochemical Technology were reconstructed based on the demand of petrochemical industry. The ideological and political contents permeation and methods, the reform of ideological and political evaluation and the educational effect of the course were introduced. The professional ethics of engineer was paid attention to cultivated and “The Spirit of Westward Migration” of university was publicized during the process of teaching. The feedback from students' questionnaires showed that 82% of students thought that the “critical thinking ability” of them had been improved. Students' classroom participation rate had increased to 100%, and the excellent rate of academic performance had increased by 32% (score > 80 points).

The study aimed to validate a measure of teachers' self-efficacy in implementing integrative science, technology, engineering, and mathematics (STEM) education-the Technological Pedagogical STEM Knowledge Survey (TP-STEMK)-in a sample of 235 teachers in Hong Kong. Confirmatory factor analysis (CFA) was conducted to test TP-STEMK's measurement validity, while structural equation modeling (SEM) was performed to examine the interrelationships among its factors. Results of the CFA showed that the four-factor model of TP-STEMK composed of self-efficacy for technological pedagogical mathematics knowledge (TPMK), technological pedagogical science knowledge (TPSK), technological pedagogical engineering knowledge (TPEK), and integrative STEM (iSTEM) has good fit to the data, providing support for its measurement validity. Moreover, results of the SEM revealed that TPMK, TPSK, and TPEK significantly and positively predicted iSTEM, with TPMK as the strongest predictor. Hence, the study was able to extend the validity of the TP-STEMK to a sample of teachers in Hong Kong.

This study selected 20 Tibetan children in a large class as the research object to explore a more effective teaching model to promote children's learning of the national common language. The research results are analyzed by SPSS data and it is found that under the AR teaching model, children's national common language learning has significant advantages in terms of understanding and language expression ability. It is suggested that teachers in the ethnic minority areas in western China guide children to carry out teaching activities with the help of AR resources on the basis of the original national common language teaching activities.

With the popularity and application of information technology in China's education industry, the demand for education and teaching resources based on the Internet is also increasing, and the trend of intelligent teaching platforms is becoming more and more obvious. Most of the mainstream teaching platforms appearing at home and abroad have similar characteristics, and it is not possible to fully understand the differences as well as their advantages and disadvantages in-depth just through the user manuals provided by each intelligent teaching platform. Based on the EduTools evaluation system, this study conducts statistical and comparative research based on a comprehensive survey of intelligent teaching platform tools.

The purpose of this study is to incorporate a collaborative flipped classroom technique using student-generated videos to increase classroom participation. Traditional flipped classroom methods depend on educators to spend resources to produce video content. However, there is uncertainty whether a scalable and sustainable method with student-generated content can be used. Student-generated videos may provide opportunities for increasing collaboration and online engagement. The lack of knowledge and evidence has motivated this pilot study for which students record short reflective videos prior or after class using a private social media application, Soqqle. This was performed across three classes of differing modules in Hong Kong and Thailand. Evaluation and analysis of the classes differ, between participation and learning improvements, although having a similar teaching method of using student-generated videos. Results were mixed. In some cases, the predictors of correlational analysis were contradicting. In one group, results show a 64.2% increase in participation compared to the COVID-19 period. In another group, a regression analysis was able to predict learning performance with 41.2% accuracy $(mathrm{p}= <. 001)$, using the number of videos watched and average duration as predictors. A teaching and learning framework for using the collaborative flipped classroom model is proposed and can be adapted by future researchers. Suggestions to further enhance the model are discussed.

Although the significance of EFL textbooks has been widely acknowledged, previous analyses of textbooks have paid little attention to learning strategies implied or presented in textbooks. By a corpus-assisted method, the present study aims to examine how instrumental texts in mainstream high school English textbooks in China are used to construct learning strategies both implicitly and explicitly. The study found an imbalance in the representation of strategies in the textbooks which partially fulfilled the requirements of the latest English Curriculum Standards for Senior High School in China. It also reveals typical patterns of learning strategies displayed in the textbooks which may shed light on cultivation of learning strategies and English textbook writing in the Chinese EFL contexts.

Since group awareness was introduced into the field of CSCL, it has become an important concept to trigger high-quality collaborative learning. This study reviewed the literature on the visualizations and effects of group awareness in CSCL. After the searching and screening process, 23 empirical studies were selected from 3 databases. Findings revealed that learners cannot easily capture the group awareness information because of its hiding. Therefore, more and more group awareness tools (GATs) have been developed as an important way for learners to perceive the process of collaboration in CSCL. This study analyzed what information is presented by different types of GATs (cognitive, behavioral, and social) and how to visualize this information. In addition, this study also focused on exploring the effects of GATs on students' collaborative learning from three aspects: collaboration process, group performance and individual performance. Finally, based on the results of literature analysis, potential future research directions were proposed.

Mobile augmented reality games are more effective for teaching and learning, and the impact of different proportions of learning content in mobile augmented reality games on preschoolers' learning outcomes is significant. For preschoolers there is a golden ratio that makes them learn better. This paper will discuss the impact of the proportion of game content on learning outcomes in mobile augmented reality games. The results show that the right proportion of instructional content in mobile augmented reality games enhances teaching effectiveness, satisfaction, entertainment and motivation. However, the proportion of learning content in play varies significantly across the age range. This study focuses on improving teaching effectiveness for teachers and designers by adjusting the proportion of instructional content in mobile augmented reality games when the content is similar.

To understand the effectiveness of the rotational synchronous teaching (RST) model on students' learning, a mediation model was conducted to investigate the effects of teaching presence and learning environment preference on college students' deep learning in RST. A total of 274 college students completed the survey. The correlation analysis results show that teaching presence and learning environment preference are positively related to deep learning. At the same time, teaching presence is also found positively related to learning environment preference. The mediation analysis results indicate that teaching presence directly predicts deep learning and also indirectly predicts deep learning via learning environment preference after controlling for gender. That is, learning environment preference plays a partial mediating role between teaching presence and deep learning.

Hybrid teaching entails conducting online and offline classes, thus combining the advantages of online and traditional teaching. The introduction of information-based teaching resources has created difficulties in teaching, learning, and teaching management. Harnessing the advantages of such teaching resources while allowing teachers and students to adapt to non-traditional teaching and learning methods is a matter of concern. Hence, this paper presents countermeasures to the problems of hybrid teaching, such as strengthening teachers' hybrid teaching training, stronger supervision and management, and formulating evaluation criteria for hybrid teaching and learning.
