The triode amplifier circuit is a classic circuit in analog electronic technology (referred to as "modulus"), and it is also the basic content and difficult points for beginners to get started. Many textbooks usually outline the composition and working principle of the triode amplifier circuit from an analytical point of view, but ignore the circuit design or construction process, resulting in most students "knowing it but not knowing why" after learning, let alone applying knowledge to solve practical engineering problems. Based on the question-oriented, teacher-led, and student-thinking inquiry-based teaching model, this paper constructs the transistor amplifier circuit, attaches importance to the teaching process, summarizes internalized knowledge and cultivates abilities through induction. Years of teaching practice has shown that the problem-oriented "transistor amplifier circuit construction" teaching model has a good teaching effect for the students of the second college.

The tripolar amplification circuit is a classic circuit in analog electronics technology ("molded electricity"), and it is also the basic content and difficulty for beginners to get started. Many teaching materials usually from an analytical point of view to summarize the composition and working principle of the tripolar tube amplification circuit, while ignoring the circuit design or construction process, resulting in most students after learning "know it but do not know why", not to apply knowledge to solve the actual problems of engineering. Based on the inquiry-based teaching mode of problem-oriented, teacher-led and student-thinking, this paper constructs the three-pole amplification circuit, attaches great importance to the teaching process, summarizes the internalized knowledge through generalization, and cultivates the ability. Years of teaching practice show that for students in two colleges and universities, the teaching mode of "tripolar amplification circuit construction" based on problem orientation has a good teaching effect.

Triode amplifier circuit is a classic circuit in Analog Electronic Technology (referred to as "analog electricity"), and it is also the basic content and key and difficult point for beginners. Many textbooks usually summarize the composition and working principle of triode amplifier circuit from the perspective of analysis, but ignore the circuit design or construction process, resulting in most students "know it but don't know why" after learning, and can't apply knowledge to solve practical engineering problems. Based on the inquiry teaching mode of problem orientation, teacher guidance and students' thinking, this paper constructs the triode amplifier circuit, attaches importance to the teaching process, summarizes the internalized knowledge and cultivates the ability. Many years of teaching practice shows that the problem-based "triode amplifier circuit construction" teaching mode has good teaching effect for the students of the second university.
