Its own logic can enlighten and optimize pupils rational thinking and innovative thinking ability from an early age. However, mathematics is not as interesting as language or art subjects. In order to obtain high-quality mathematics teaching results, primary school mathematics teachers must master good mathematics education methods. At present, the problem guidance method of mathematics education has been widely used in the teaching process of various subjects. Primary school mathematics teachers should pay enough attention to it, design problems and apply problems rationally, and create an efficient mathematics teaching classroom for students.展开更多

In physics teaching of senior high school, adopting problem-led teaching mode can stimulate students' interest in learning, encourage students to explore the knowledge they have learned, and promote the efficiency of classroom teaching.展开更多

Different from most of the existing literature in which the simultaneous attack problem is formulated as a consensus problem of missiles＇ time-to-go estimates, this paper formulates it as the consensus problem of missiles＇ ranges-to-go. Based on this strategy, novel distributed guidance laws are proposed to solve the simultaneous attack problem with the target of unknown maneuverability.Adaptive control method is introduced to estimate the upper bound of the target＇s acceleration. The effectiveness of the proposed guidance laws is verified both theoretically and numerically.展开更多
文摘Mathematics is a compulsory subject for students in primary school. Its own logic can enlighten and optimize pupils rational thinking and innovative thinking ability from an early age. However, mathematics is not as interesting as language or art subjects. In order to obtain high-quality mathematics teaching results, primary school mathematics teachers must master good mathematics education methods. At present, the problem guidance method of mathematics education has been widely used in the teaching process of various subjects. Primary school mathematics teachers should pay enough attention to it, design problems and apply problems rationally, and create an efficient mathematics teaching classroom for students.
文摘The so-called problem leading refers to the teacher through the creation of problem scene, to guide students to find out the problem, solve the problem, so as to deeply understand the knowledge, and can apply the knowledge to solve the problem of the teaching model. In physics teaching of senior high school, adopting problem-led teaching mode can stimulate students' interest in learning, encourage students to explore the knowledge they have learned, and promote the efficiency of classroom teaching.
