A cross-disciplinary Renaissance movement is unfolding on the campuses of national high schools and elementary schools. Pingtung High School’s mathematics and science gifted class combines music and natural science hip-hop courses to create beautiful rap songs using physical and chemical principles. Students from Penghu Pengnan Junior High School use ruler and compass drawing and vertical line principles in mathematics to create giant sand paintings.

"It turns out that Doppler also understands love/My dada's horse hooves are running towards you at full speed/My deep eyes are like black holes/Einstein said/The gravity field distorts time and space." In the "Rap ATP" class led by Pingzhong's music teacher Huang Jinlan and chemistry teacher Zhang Yaochang, students not only created their own lyrics and music, but also used mathematical formulas or their favorite scientists to create hip-hop rap works that blended chemical elements with music.

Huang Jinlan said that from Broadway musicals to hip-hop rap, she first let students understand the evolution of beauty, and then asked students to create in groups. During the process, the students were unable to master the tone of rapping and failed many times. Therefore, she spent special time training students to speak in rapping and published it at the end of the semester.

Huang Jinlan said that because the melody, chords and lyrics have to be created by the students themselves and completed with computer software, the challenge is high, and the time is also very tight to create a song in one semester. The key is to allow students to switch from the "receptive" learning mode they were accustomed to in the past to active presentation, and to convert words into live performances. The students have made great breakthroughs, and the teachers have also learned from each other.

Penghu Pengnan Junior High School uses the visual arts course to ask students to describe the customs and characteristics of the living community and the cultural or natural landscapes in Penghu tourist attractions. The art teacher then examines the feasibility of the graphics and discusses with the students how to use scale and straight lines. geometric figures such as rulers and compasses, and clearly draw the selected figures. Through the teaching of cross-domain courses, students can re-understand mathematics and get close to ruler and compass drawing.

Wang Zixiang, an art teacher at Pengnan Junior High School, said that he has done this course twice, and the works are "Dried Fish" and "Double Star Stone". The work is 30 meters in diameter. Wang Zixiang said that she first asked students to draw sketches in art class, and then asked mathematics teacher Zheng Weijie to teach them how to use rulers and compasses to draw. Then, when they went to the beach, they used plastic ropes and iron rakes as compasses to draw. Pattern production is the most difficult stage. "Not all imaginable patterns can be drawn on the beach."

"Creating on the beach must have the right time, place, and right people," Wang Zixiang said. In addition to checking whether the beach is flat, the ebb tide must also recede to the "moment of the greatest tidal range," and it must be a time when students are in school. When the tide begins to recede, you have to start painting. There are only 90 minutes, "all the steps must be calculated." I have simulated it twice in school before setting off, and I must not delay it.
