The first class in the afternoon was free activity ti. Normally, this period should have been spent in extracurricular activities, but due to what happened in the morning, all the students stayed obediently in the classroom.
Because he had to teach the students, Xu Renfei rarely got serious. Taking advantage of the self-study period, he brought over the physics book and the test papers Bi Xia had done earlier and started reviewing.
After reviewing as quickly as possible, he turned around and started discussing the classmates’ learning status with Bi Xia, then began preparing the lesson, hoping to help the students rember what they had learned in the simplest and fastest way.
It had been a long ti since ng Luo last engaged in academic subjects, so he struggled a bit at first. He felt embarrassed to turn around and ask Bi Xia and Xu Renfei, worried about disturbing them.
But fortunately, ng Chi, who used to be the top student in the class, was also good at studies. He could help ng Luo with so of the questions. Zhao Wenxin, who was already very familiar with ng Luo, joked that the two of them were Double ng siblings.
After learning about the decision made by his classmates, Zhang Zhongxing quietly took a peek through the back door window. Just one glance made him grin; the current H class and the old H class felt like two completely different classes...
He pondered for a mont, then turned back to the office and sent an electronic copy of H class’s grade report to Bi Xia, with a note: Based on grade analysis, weaker subjects are mainly due to poor foundational skills, so teaching with a focus on the basics is best.
Upon receiving Zhang Zhongxing’s ssage, Bi Xia smiled. She had just been planning to ask 007 to pull up a grade report and subject analysis for H class, and their horoom teacher had sent it in right on ti.
So Bi Xia and Xu Renfei borrowed a laptop from Lin Bin, who always carried his computer, and quickly compiled the weak areas of each student in the class, then organized the basic knowledge.
To ensure the study plan they developed would be effective, Bi Xia asked Lin Bin to create a comparison chart, and then had 007 make an estimate of the potential for grade improvent. Once confird, she sent a copy to Zhang Zhongxing.
The mont Zhang Zhongxing’s ’OK’ ssage ca through, Bi Xia and Xu Renfei exchanged glances and smiled slowly. Now, all that was left was to take action.
During the second class, Bi Xia ca to the podium. She had noticed that nearly two-thirds of the students in the class were significantly behind in math, and math was a subject that greatly affected their scores. So the plan was to tutor math first, followed by physics and chemistry.
The kids in H class were not new to studying; they simply couldn’t retain the previously taught concepts, had weak foundational skills, and took much longer to solve problems. When faced with complex problems requiring multiple formulas, they struggled to make connections, their minds getting stuck in a loop, and they felt hopeless in math, eventually giving up.
Therefore, the first thing Bi Xia had to do was to organize all the formulas that would be tested in the midterm exam, which ant all the formulas learned recently.
Among them, the most important were the basic trigonotric identities and the trigonotric inducent formulas. Although these were just two nas, within them, there were definition formulas, function relationships, inducent formulas, basic formulas, and so on.
Bi Xia now drew a right-angled triangle on the blackboard, labeling A, B, and C as well as the opposite side a, the adjacent side b, and the hypotenuse c.
"Actually, trigonotric functions are not as complicated as we imagine. Although there are many formulas that give us headaches, as long as we rember the most basic ones, we can derive the others."
"Of course, I don’t recomnd trying to derive formulas during the exam. I think the best way is to morize each formula firmly, keeping it in your mind."
"With the midterm exam coming next Friday, in these few short days, I can’t teach you difficult problems and points. Our most urgent and effective thod is to focus on basic knowledge."
Bi Xia stood at the podium, pointing to the blackboard, "So next, let’s clarify the definitions of trigonotric functions. It’s actually quite simple; as long as you listen carefully, you’ll understand."
