From the learning of these researches we get clearer that English teaching and learning is a continuous process in which many interrelated and intrinsic factors work together. Furthermore, we know that teachers＇ beliefs on teaching and learning play an important role in class. During the process of learning and teaching, a teacher＇s own learning from relevant books on education and learning helps a lot in increase teachers＇ awareness about English teaching and learning, and improving the classroom teaching. In this paper three effective applications of the results of the research of teacher development are introduced, which shows that a teacher is a decisive factor in the classroom setting and the research and learning about teacher development is useful for a teacher to improve himself or herself as a teacher.展开更多

The writer of this paper suggests a teaching model by using Internet in after-class activities, which is supposed to be helpful in promoting students＇ participation in class activities and enhancing their learning autonomy.展开更多

While the class imbalance issue has been extensively investigated within the multi-class paradigm, its study in the MDC context has been limited due to the imbalance shift phenomenon. A sample’s classification as a minor or major class instance becomes ambiguous when it belongs to a minor class in one LD and a major class in another. Previous MDC methodologies predominantly emphasized instance-wise criteria, neglecting prediction capabilities from a dimension aspect, i.e., the average classification performance across LDs. We assert the significance of dimension-wise metrics in real-world MDC applications and introduce two such metrics. Furthermore, we observe imbalanced class distributions within each LD and propose a novel Imbalance-Aware fusion Model (IMAM) for addressing the MDC problem. Specifically, we first decompose the task into multiple multi-class classification problems, creating imbalance-aware deep models for each LD separately. This straightforward method performs well across LDs without sacrificing performance in instance-wise criteria. Subsequently, we employ LD-wise models as multiple teachers and transfer their knowledge across all LDs to a unified student model. Experimental results on several real-world datasets demonstrate that our IMAM approach excels in both instance-wise evaluations and the proposed dimension-wise metrics.展开更多

Through internet technology, knowledge is taken as the core resource, and fragmented time is used for learning, which provides a wider space for learners to learn individually. With the help of WE Learn accompanying classroom network teaching platform, starting from the current situation of English teaching in colleges and universities, this paper analyzes the current predicament of traditional English teaching in colleges and universities, and puts forward some suggestions and countermeasures for the English teaching model under the mixed online and offline teaching environment.展开更多
