PBL (Project-Based Learning), or project-based teaching, is a problem-oriented teaching method that designs learning scenarios and is a student-centered educational approach based on the real world. The teaching of PBL involves subjects such as mathematics, physics, technology, engineering, and design, so the teaching content is actually a comprehensive course compiled around various problems. This requires students to solve problems through interdisciplinary and cross-field learning.

In order to successfully complete PBL projects, students must integrate their knowledge from various disciplines and life experiences, and cooperate with teams to solve various problems.

During this process, the behaviors such as exploration, communication, innovation and collaboration that students engage in are beyond the reach of traditional teaching models. It is precisely through these behaviors that students' comprehensive qualities have been comprehensively enhanced.

Experimental purpose:

Today's good life is hard-won. We should cherish and protect our homeland. Do you know the way ancient people built wooden houses? How do the electric lights in modern homes work? So today, let's work together to build our own warm home.

Principle application

Principle analysis

Knowledge Point 1: Mortise and tenon (Pinyin) structure: Ancient people mostly built houses with wooden structures. Moreover, metal nails are rarely used for reinforcement. The diligent and intelligent ancients used mortise and tenon joints to build the framework of their houses. The house is strong and durable. For instance, the Forbidden City is constructed with wooden mortise and tenon joints. It remains as solid as ever for hundreds of years. Many of the models we build today are constructed using mortise and tenon joints.
Knowledge Point 2: LED Lights and Direct Current: There are many kinds of light sources that emit light in our daily life. For example: sunlight, candles, incandescent lamps, power-red lamps, LED lamps, etc. Many red lights and advertising lights use LED lights. The LED lights used today are driven by a DC power supply. All power supplies that distinguish between positive and negative poles are DC power supplies. The 220V household and 380V industrial electricity in our daily life belongs to alternating current power supply. There is no distinction between positive and negative poles. The LED light bead has two pins, one long and one short. The longer pin is connected to the positive pole. The positive terminal is generally indicated by a red line. The short pin is connected to the negative terminal. The negative wire is generally represented by a black wire. The LED beads won't light up when connected in reverse. Dc lamp beads with tungsten filaments can be easily burned out and damaged if connected in reverse.
