Course Advising Day#

Theme: A student helper explains school subjects and numbers to new university students.

Leo worked at the university help desk on advising day. Many new students came to ask about their course choices. One student loved reading about societies, so Leo suggested sociology and politics. Another wanted to understand human behavior through psychology. Leo also advised a quiet boy who loved deep thinking to study philosophy and formal logic. On the same desk, colorful guidebooks for history and geography were arranged neatly side by side.

Next, several business students arrived with questions. A young woman wanted to learn about markets, so Leo introduced her to economics and marketing. For working with business numbers, she needed accounting and a course on how to audit company records. She also asked about a famous corporate merger in the news. Leo then explained how modern food production depends on agriculture, and how international trade relies on careful logistics to move products around the world.

Science and technology fans had questions too. Leo talked about living cells in biology, chemical reactions in chemistry, and forces in physics. For students who liked building machines, engineering was very popular, especially modules in mechanics and electronics. However, Leo reminded them that every science student needed strong skills in maths and statistics to analyze their laboratory results.

To help them prepare, Leo drew simple numbers on a whiteboard. He reviewed basic arithmetic, shapes in geometry, letters in algebra, and rates of change in calculus. “Five plus five gives a sum of ten,” he said. “The total is ten. When both sides are balanced, we write an equation to show they are identical. If you see ten minus two, you simply subtract two. You can multiply two by three to get six, or divide six by two to get three.”

Leo then explained other parts of numbers. “In division, the number being divided is the dividend, and what is left over is the remainder,” he said. He wrote a fraction to show a rational number. He told them that room size was a fixed parameter today, while the number of visitors was an unpredictable variable. A group could have an even number of four members or an odd number of three. To find the mean test score, they should add all marks together and divide by the class size.

Finally, Leo spoke about course limits. If student numbers were to double, the university would open a second room; if they were to triple or quadruple, they would move to the main hall. Because there were multiple popular classes, each room had a maximum of forty students and a minimum of ten. “We have approximately fifty students waiting in the hall right now,” Leo laughed as he ended the session, happy to help everyone find the right path.

选课咨询日#

主题： 一名学生助理向大学新生讲解学科门类与数字运算。

利奥在选课咨询日的大学服务台值班。许多新生前来咨询他们的选课事宜。有一位学生喜欢阅读关于社会的书籍，于是利奥推荐了社会学和政治学。另一位学生想通过心理学来理解人类行为。利奥还建议一位喜欢深思的文静男生学习哲学和形式逻辑。在同一张桌子上，历史和地理的彩色指南整齐地并排摆放着。

接下来，几位商科学生带着问题走了过来。一位年轻女士想了解市场，于是利奥向她介绍了经济学和市场营销。为了处理商业数据，她需要学习会计学以及一门关于如何审计公司记录的课程。她还询问了新闻中报道的一起著名企业合并案。随后，利奥解释了现代食品生产如何依赖于农业，以及国际贸易如何依靠精细的物流将产品运往世界各地。

理工科爱好者们也有疑问。利奥谈到了生物学中的活细胞、化学中的化学反应，以及物理学中的力。对于喜欢制造机器的学生来说，工程学非常受欢迎，尤其是机械学和电子学模块。然而，利奥提醒他们，每位理科生都需要扎实的数学和统计学技能，以便分析他们的实验结果。

为了帮助他们做好准备，利奥在白板上画出了一些简单的数字。他复习了基础算术、几何中的形状、代数中的字母，以及微积分中的变化率。“五加五得到的和是十，”他说，“总数是十。当两边平衡时，我们写出一个方程式来表示它们是完全相同的。如果你看到十减二，你只需减去二。你可以用二乘以三得到六，或者用六除以二得到三。”

随后，利奥解释了数字的其他部分。“在除法中，被除的数是被除数，剩下的部分是余数，”他说。他写下了一个分数来表示有理数。他告诉他们，今天房间的大小是一个固定的参数，而访客的人数则是一个不可预测的变量。一个小组可以有四名成员的偶数，也可以有三名成员的奇数。要计算测试成绩的平均值，他们应该把所有分数加在一起，然后除以班级人数。

最后，利奥谈到了课程的人数限制。如果学生人数翻倍，大学将开放第二间教室；如果翻三倍或翻四倍，他们将搬到主礼堂。因为有多门热门课程，每个教室的上限为四十名学生，下限为十名。“现在大厅里大约有五十名学生在等候，”利奥在结束咨询时笑着说，他很高兴能帮助每个人找到正确的方向。
