This research reports on implementing the integrated laboratory work to achieve effective learning in the biochemistry course. The integrated laboratory work includes three stages: pre-laboratory, lab work, and post-laboratory. In other words, the three stages include planning, implementing, and evaluating investigation activities in the laboratory. The research design used was a posttest control group design consisting of a control and an experimental group. There were 67 students as respondents, who were divided into control (N = 33) and experimental (N = 34) groups. Practical skills were measured using an assessment rubric with the involvement of the observer. The categories of practical skills measured were procedural skills, observation skills, interpretation skills, and reporting skills. Attitude toward biochemistry was measured using a questionnaire with five Likert scales. The indicators of attitudes toward biochemistry used were liking for a biochemistry theory lesson, liking for biochemistry laboratory work, evaluative beliefs about biochemistry, and behavioral tendencies to learn biochemistry. The influence of the implementation of the integrated laboratory work on the students' practical skills and attitudes toward biochemistry was analyzed using MANOVA. The research result shows that implementing the integrated laboratory work improves students' average scores in practical skills and attitudes toward biochemistry. All the practical skills and attitudes categories in the experimental group have a higher score than those in the control group. The reason is that the work of the integrated laboratory can prepare students to conduct better investigations in biochemistry laboratory work.

生物化学课程中提高学生实践技能和生物化学态度的综合实验室工作

本研究报告了如何实施综合实验室工作以实现生物化学课程的有效学习。综合实验室工作包括实验室前、实验室工作和实验室后三个阶段。换句话说，这三个阶段包括实验室调查活动的规划、实施和评估。使用的研究设计是由对照组和实验组组成的后测对照组设计。有 67 名学生作为受访者，分为对照组（N  = 33）和实验组（N  = 34）。实践技能是在观察员的参与下使用评估标准来衡量的。测量的实践技能类别包括程序技能、观察技能、解释技能和报告技能。使用包含五个李克特量表的调查问卷来测量对生物化学的态度。对生物化学态度的指标是喜欢生物化学理论课、喜欢生物化学实验室工作、对生物化学的评价信念以及学习生物化学的行为倾向。利用多元方差分析分析了综合实验室工作的实施对学生实践技能和生物化学态度的影响。研究结果表明，实施综合实验室工作提高了学生实践技能和生物化学态度的平均成绩。实验组所有实践技能和态度类别的得分均高于对照组。原因是综合实验室的工作可以让学生为更好地进行生物化学实验室工作的调查做好准备。
