Inquiry-based laboratories are acknowledged as the preferred method of instruction for development of research skills. Much has been written about changes in student performance associated with inquiry, but less is known about how students view the inquiry-based format or whether they perceive a benefit from this type of instruction. The Student Assessment of Learning Gains (SALG) survey was used to evaluate and compare student reactions to the new, inquiry-based laboratories of a lower-division undergraduate curriculum, from implementation to the present (an interval of 3 yr). Initial student response to the format and value of the inquiry labs improved over time. The quality of the graduate teaching assistants and the clarity of the laboratory manual were important variables influencing student perception. A student's perception of his/her retention of lab-related skills was strongly associated with perceptions of gains in those skills. Student responses reflect their most current laboratory experience and not a cumulative effect of participation in the core series of courses. Student success in the inquiry format was not associated with gender or status as a transfer student. The majority of students believe that their experiences in the lower-division inquiry labs have prepared them for upper-division course work.
基于探究的实验室被公认为培养研究技能的首选教学方法。关于与探究相关的学生成绩变化已有很多著述,但对于学生如何看待基于探究的形式,或者他们是否认为这种教学方式有益,却知之甚少。学习收获学生评估(SALG)调查被用于评估和比较学生对低年级本科课程中新型基于探究的实验室从实施到目前(三年时间间隔)的反应。随着时间推移,学生对探究实验室的形式和价值的最初反应有所改善。研究生助教的质量和实验手册的清晰度是影响学生看法的重要变量。学生对自己保留与实验相关技能的认知与对这些技能提升的认知密切相关。学生的反应反映了他们当前的实验室经历,而非参与核心系列课程的累积效应。学生在探究形式中的成功与性别或转学生身份无关。大多数学生认为他们在低年级探究实验室的经历为他们的高年级课程学习做好了准备。
