Introductory biology students are typically overwhelmed in the laboratory. Many of the students are unsure of how to prepare for each session. Two online pre-laboratory modules were developed to introduce the students to the concepts required for laboratory. The students studied the information in the modules and took an online quiz prior to each lab session. Of the 49 students who reviewed the first module and took the online quiz, the average quiz grade was 83.7% ± 12.8. A control group that did not review the online module had an average quiz grade of 53.6% ± 17.5. Of the 20 students who reviewed the second module and took the online quiz, the average quiz grade was 76% ± 15.0. The average quiz grade of the control group was 47.2% ± 16.5. The students were required to prepare laboratory reports for each session. Students who were required to review the modules received slightly higher grades on their laboratory reports compared to the control group. The students and faculty took a survey to determine their perceived impact of the modules on laboratory preparedness and performance. Both the faculty and students agreed that students are typically underprepared for lab (100% and 62%, respectively). Eighty-five percent of the students and all faculty felt that the modules did help them with preparation for the lab. Eighty-eight percent of the students and 76% of the faculty reported that the modules helped them to prepare their laboratory reports. These data clearly indicate that the pre-laboratory modules do enhance student preparedness and performance in the laboratory.
基础生物学课程的学生在实验室通常会应接不暇。许多学生不确定如何为每次实验课做准备。开发了两个在线实验前模块，向学生介绍实验所需的概念。学生在每次实验课之前学习模块中的信息并进行在线测验。在49名复习了第一个模块并参加在线测验的学生中，测验平均成绩为83.7%±12.8。未复习在线模块的对照组测验平均成绩为53.6%±17.5。在20名复习了第二个模块并参加在线测验的学生中，测验平均成绩为76%±15.0。对照组的测验平均成绩为47.2%±16.5。要求学生为每次实验课撰写实验报告。与对照组相比，被要求复习模块的学生在实验报告上的成绩略高。学生和教师进行了一项调查，以确定他们认为这些模块对实验准备和表现的影响。教师和学生都认为学生通常对实验准备不足（分别为100%和62%）。85%的学生和所有教师都认为这些模块确实帮助他们为实验做了准备。88%的学生和76%的教师报告说这些模块帮助他们撰写实验报告。这些数据清楚地表明，实验前模块确实提高了学生在实验室的准备程度和表现。
