The purpose of this study is to explore successful classroom management from three aspects: effective time management in a classroom, effective teaching in small classes, and effective use of handouts for a lecture. The findings reveal that it is crucial for language teachers to deliver enough knowledge during the limited time. And then small class teaching is an inevitable trend that teachers should focus on. Finally, despite the disadvantages of handouts, using handouts effectively can benefit both teachers and students.展开更多

The Class-F PA reduces the overlap of drain voltage and current by tuning harmonic impedance so that high efficiency is achieved. This paper begins with the principle of class-F PA, regards the third harmonic voltage as an independent variable, analyzes the influence of the third harmonic on fundamental, and points out how drain efficiency and output power vary with the third harmonic voltage with an I-V knee effect. Finally, the best third harmonic impedance is found mathematically. We compare our results with the Loadpull technique in advanced design system environment and conclude that an optimized third harmonic impedance is open in an ideal case, while it is not at an open point with the I-V knee effect, and the drain efficiency with optimized third harmonic impedance is 4% higher than that with the third harmonic open.展开更多

Although these gadgets are useful and convenient, a majority of students(whether they are higher learning students or low level students) are becoming more and more dependent on them. The aim of this study is to find out the reason why college students are addicted to cell phone and the impact of mobile phone abuse on their academic performance as well as propose feasible solutions for teachers to motivate learners to take an active participation in English speaking class by adopting advanced mobile phone technologies to improve learning efficiency.展开更多
