我们小组所研究的是生物科学,要研究各种生物的生长发育过程,需要在长时间内才能完成。因而一般同学都认为要订具体计划是很困难的。就拿植物来说,如何根据其发育的各个阶段及生长的各个时期的规律来进行管理和研究,由於各地的自然条件不同,难於准确地拟出计划。因此,许多人虽然也明白计划的重要,但总是觉得难订,有的只是笼笼统统地订了几点目的要求,有的虽然订得比较详细,但是由於不符合实际,结果也不能执行,最後还是打乱仗。结果,同学们的情绪也就渐渐低落了,甚至还有个别同学,要求退出小组,或是全小组最後完全垮台,我们这里两学期来,都有过这样的情况,所以,事先订好切实可行的计划,是一项很重要的工作。在这里我简单地把我们上学期是怎样拟订活动计划的一些体会谈一谈。上学期,我们小组实验的题目是“南瓜的生产性杂交”,材料是用长身南风品种和圆身南瓜品种进行有性杂交,以便提高产量,并获得杂种,准备明年继 Our team is studying the biological sciences, to study a variety of biological growth and development process, need to be completed in a long time. Therefore, most students think that it is very difficult to formulate a concrete plan. Take plants as an example, how to conduct management and research according to the law of each stage of their development and each period of growth, because of the different natural conditions in different places, it is difficult to draw up a plan accurately. Therefore, while many people understand the importance of the project, they always find it hard to make any decisions. However, some of them just set a few general requirements for the purpose of the project. Some of them, although more detailed, are not implemented because they are not realistic Finally, disrupt the battle. As a result, the mood of the students is also gradually declining. There are even some students who asked to leave the group or the whole group finally collapsed completely. We have had such a situation in both semesters here. The plan is a very important task. Here I will simply talk about some of the experiences we learned during the last semester about how to plan an activity. Last semester, our team experimented with the topic of “Productive Hybridization of Pumpkin”. The material is a sexual cross with long southerly varieties and round pumpkin varieties in order to increase production and obtain hybrids ready for next year
