"Embryonic development" illustrates the weight of maternal love.
"The battle has finally begun!" With each ring of the bell, we stood on the three-foot-wide platform of our teaching careers. The night before, my heart was filled with anxiety and unease; I tossed and turned, unable to sleep soundly. This was the most uncertain lesson I'd ever given; there was no trial lesson, just a direct entry into the battlefield. Now, it was finally our turn.
With the children's greetings of "Hello, teacher!", our nervousness subsided. Our eyes and hearts were filled with them, thinking about how to guide their thinking and elicit the answers I wanted. The topic of this lesson was embryonic development, and we were teaching second and third graders. Because there were some technical terms like "fertilized egg," "placenta," and "umbilical cord," we used comics and videos to help them understand more vividly.
The students were particularly excited when we explained fetal heart development and the mother's morning sickness. We asked the children to count their heartbeats in one minute.
"Teacher, mine was 60!" "Mine was 72!" "Mine was the most, 80!" the students answered excitedly.
"You are all very capable, but a fetus's heartbeat is 150 beats per minute at two months. Your mothers also start experiencing morning sickness at this time, vomiting everything they eat, which is very difficult."
This lesson was to help the children understand the hardships their mothers endure during their ten months of pregnancy, to cherish life, and to learn to be grateful to their parents. Furthermore, we also learned from the children that teaching is no longer about how much we tell them, but about letting them think, experience, and internalize the knowledge.
