To help instructors in evaluating innovations in biomechanics instruction, a standardised test of the key concepts taught in the introductory biomechanics course was developed. The Biomechanics Concept Inventory (BCI) consists of 24 questions that test four prerequisite competencies and eight biomechanics competencies. Three hundred and sixty seven students from ten universities throughout the United States took the test at the beginning and the end of the introductory biomechanics course. Analysis of a sub-sample of the students showed that the BCI was reliable with typical errors in internal consistency and test-retest conditions of 1.4 and 2.0 questions, respectively. Mean pre-test scores (8.5 +/- 2.0) significantly (p < 0.0001) improved to 10.5 +/- 3.2 in the posttest (n = 305). Typical biomechanics students could correctly answer half of the prerequisite questions on the pre-test. Instruction resulted in a mean normalised gain (g) of 13.0% of maximum possible improvement that was consistent with research on traditional instruction in introductory physics courses. It was concluded that the BCI could be an effective tool to evaluate the overall effect of pedagogical strategies on student learning of key biomechanical concepts in the introductory biomechanics course.
为帮助教师评估生物力学教学中的创新，开发了一项针对生物力学入门课程中所教授关键概念的标准化测试。生物力学概念量表（BCI）由24个问题组成，用于测试四项先修能力和八项生物力学能力。来自美国十所大学的367名学生在生物力学入门课程开始和结束时参加了该测试。对部分学生样本的分析表明，BCI是可靠的，在内部一致性和重测条件下的典型误差分别为1.4个和2.0个问题。前测平均得分（8.5±2.0）在测试后显著提高（p<0.0001）至10.5±3.2（n = 305）。典型的生物力学专业学生在前测中能正确回答一半的先修问题。教学带来的平均标准化增益（g）为最大可能提高的13.0%，这与入门物理课程传统教学的研究结果一致。得出的结论是，BCI可能是评估教学策略对生物力学入门课程学生关键生物力学概念学习的总体效果的有效工具。
