Wireless sensors application in smart English classroom design based on artificial intelligent system

In the traditional intelligent English classroom teaching, the efficiency of students' learning is often affected by many external environments, such as the influence of learning environment, the influence of students' own condition, and the influence of teachers' teaching mode. In view of these problems, we propose a wireless sensor network technology intelligent teacher management system, which can reduce the influence of the above factors on students' learning efficiency and improve students' learning efficiency. Make students more focused on learning. The system can monitor the state of students through wireless sensors. When the students are in bad condition, the system can adopt certain measures to enhance the enthusiasm of students. At the same time, the state of students and the state of the classroom will be recorded in the internal background system, the system managers can timely monitor the state of students and teachers, and give some guidance and feedback to students and teachers. This learning system is based on machine-free learning and sensor development. It can adjust the classroom environment to suitable conditions and make students more motivated to learn. Teachers can also have a more stable play, will not cause waste of classroom time and attention loss and other phenomena. When students feel tired or sleepy in class, the management system can also actively remind students. Observing the students' state at all times in the traditional classroom will lead to the teacher's distraction, but the teacher has to observe the students' state while lecturing. This may affect teachers and affect their teaching level, and the use of this automated classroom detection technology can solve such problems. Machine learning is to improve the calculation method through various experiences, which is also a problem in the field of artificial intelligence.

Building an automated English sentence evaluation system for students learning English as a second language

This paper presents an automated scoring system which grades students’ English writing tests. The system provides a score and diagnostic feedback to students without human’s efforts. Target users are Korean students in junior high schools who learn English as a second language. The system takes a single English sentence as its input. Dealing with a single sentence as an input has some advantages on comparing the input with the answers given by human teachers and giving detailed feedback to the students. The system was developed and tested with the real test data collected through English tests given to third grade students in junior high school. Scoring requires two steps of the process. The first process is analyzing the input sentence in order to detect possible errors, such as spelling errors and syntactic errors. The second process is comparing the input sentence with given answers to identify the differences as errors. To evaluate the performance of the system, the output produced by the system is compared with the result provided by human raters. The score agreement value between a human rater and the system is quite close to the value between two human raters.     

Development and evaluation of multimedia whiteboard system for improving mathematical problem solving

This study developed a web-based multimedia whiteboard system to help students learning with mathematical problem solving. The purpose is to promote a new online mathematical learning model that students not only use electronic whiteboard to write down their mathematical problem solving solutions but also use voice recording tool to give oral explanations about their thinking behind the solutions. To cultivate students’ critical thinking capability and encourage collaborative peer learning, the new learning model also requests students to criticize others’ solutions and reply to others’ arguments. With the multimedia supporting tools, students can communicate easily with each other about what they think and how they solve mathematical problems. We have conducted an experiment with sixth grade primary school students for evaluation. After the experiment, a questionnaire about students’ attitude toward the multimedia whiteboard system for math learning was then held. The results show that students were satisfied with the use of the multimedia whiteboard system for helping them with learning fractional division. Most students were interested in studying mathematics with the multimedia whiteboard system and thought this tool is particularly useful for doing collaborative learning. After analyzing the recorded solving processes and discussions content of students, we found that the performance of female students was superior to male students in communications and mathematical problem solving. Additionally, students with higher final exam grades had better mathematical abilities for doing critiques, arguments and communications.
