In China there is a trend in English language teaching for children which is to focus on listening and speaking instead of grammar and spelling. This research seeks to develop children's spelling ability in foreign language learning as English for instance to prove it is actually beneficial for children's language ability to acquire spelling skills in a foreign language in their early age. The research provides experiments and data in children's reading, speaking, writing and listening in both mother language and the foreign language after helping the children acquire the foreign language spelling ability.

MOOC has become an important channel to promote the professional development of teachers. However, despite the global presence and scale, some critical challenges still persist in MOOC. Some of these reported challenges include lack of learner engagement, limited practical motivation and feeling of isolation, all of which in turn contributes to low performance. These issues could be addressed through innovative teaching and learning strategies based on teaching presence . In this paper, we enhance the sense of teaching presence suitable for teacher education MOOC environment, and investigates and analyzes the effect of teaching presence on performance through empirical research. The study found that the enhanced teaching presence in the teacher education MOOC environment has a significant impact on teachers' practical motivation and learning engagement.

The use of augmented reality (AR) within educational settings has seen substantial growth in recent years. The highly immersive, engaging nature of AR offers a novel approach to second-language teaching. This quasi-experimental study investigated the efficacy of using AR in children's second-language acquisition (SLA). 52 kindergarten children participants were divided into experimental and control groups. Results revealed the use of AR to be effective, with those in the AR group exhibiting significantly greater performance on both same-day and 3-day delayed productive recognition tests, and intrinsic motivation whilst learning vocabulary than the control group. Given these findings, the paper speculates on why AR might improve kindergarten students' acquisition of English vocabulary, whilst providing suggestions for future research into the use of AR for SLA by kindergarten students.

At present, some colleges and universities use the recruitment system to complete the registration and review of candidates in the recruitment work, but the review work still requires reviewers to spend a lot of time to complete. In addition, candidates submit malicious incorrect registration information to disrupt recruitment, which not only increases the workload of reviewers, but also affects the efficiency of recruitment. Candidates need to upload scanned copies of certification materials (such as ID card, degree certificate, graduation certificate, etc.) when registering. Some candidates are worried about whether the information will be leaked and the reviewers are unfair in reviewing for personal gains. In response to these problems, this article proposes to add text recognition to the recruitment management system of a university teacher to complete the system's automatic registration review. Based on the traceability and non-tampering characteristics of blockchain technology, the security and traceability of registration information are guaranteed. Kind of optimization plan. By analyzing the system process, selecting a third-party API interface to complete text recognition, and combining the simple filtering function of the system to build an automated audit function of the system. Select the candidate's registration information as the traceability object, optimize the system process, write smart contracts, web3.js connect the system and the blockchain. Experiments have proved that the automated audit function is automatically executed after candidates submit the registration form, and the average audit speed is 550ms. Reduce the workload of reviewers and improve recruitment efficiency. If the candidate has questions about the review process, the candidate can retrospectively verify whether the registration information has been tampered with through the blockchain, which ensures the fairness of the recruitment work.

The analysis of classroom teaching behavior is of great significance to improve the teaching quality of teachers, but there are few researches on teaching behavior and teaching model analysis based on speech processing. This paper proposes a method of speech separation between teachers and students based on speaker diarization, which can help educators distinguish the teaching model objectively by identifying and analyzing the speech acts of teachers and students in the classroom. Firstly, the speaker segmentation based on Bayesian distance is used to detect and segment the classroom audio. Then, based on the pre-trained speaker model, speaker detection and clustering are performed on multiple segments of speech processed by speaker segmentation. Finally, the speech acts distribution in the classroom is visualized, and the teaching model is distinguished based on the Student-Teacher analysis method. This paper uses classroom audio collected in the classrooms of two elementary schools as the experimental data. The experimental results show that the method proposed in this paper achieves 74.0% and 98.28% accuracy in speaker segmentation and speech recognition, respectively. And this experiment takes a Chinese open class as an example to analyze and discuss its teaching model in detail. The research can help teachers summarize classroom teaching effect in time, and improve the quality of classroom teaching.

Python's naming convention provides suggestions on naming style, but these suggestions are not always clear for beginners who struggle to understand the usefulness of the conventions. In this research, we studied two properties that affect naming, namely, name-length and style. We analyzed python code from five professional project libraries and compared the name statistics with those obtained from student code. Our results show that, compared to students' work, expert developers use longer names (more descriptive) and are more closely compliant with the existing python naming convention. This research provides specific recommendations on the length and style of naming integers, floats, data structures, functions, function arguments and classes for students of Python.
