This article presents the results of a survey of the 251 undergraduate dietetic programs for course content and level of the biochemistry course most frequently used to satisfy competencies in biochemistry under Plan IV of the ADA in 1979-80. It showed that a common core of information was stressed by all biochemistry instructors, but there was great variability in content and level of material covered and the textbook chosen, depending on whether the biochemistry course was offered to dietetic majors only, in classes with other nonchemistry majors, or in classes with chemistry majors. Variability was also seen in the time allotted for biochemistry--39 to 280 hours (total lecture and required laboratory hours); laboratory requirements--only 71%; and departmental affiliation of the instructor--17 different departments, primarily of chemistry (80%), biology (8%), and home economics (4%). Topics given greatest emphasis were descriptive ones, such as definitions, simple structures, and reactions of intermediary metabolism in general terms. Topics given least emphasis were those involving mechanistic and quantitative biochemistry, such as respiratory quotient (RQ), enzyme kinetics, calculations of energy from fat and carbohydrates, and specific structures of vitamins, ketones, and metabolic intermediates. The lack of communication between biochemistry and nutrition instructors and the great differences in the preparation of dietetic majors in biochemistry are sources of concern.
本文介绍了一项针对251个本科饮食学专业课程内容以及1979 - 1980年美国饮食协会计划四(Plan IV of the ADA)中最常用于满足生物化学能力要求的生物化学课程水平的调查结果。结果表明,所有生物化学教师都强调了信息的共同核心,但根据生物化学课程是仅面向饮食学专业学生、与其他非化学专业学生一起上课,还是与化学专业学生一起上课,所涵盖材料的内容、水平以及所选教科书存在很大差异。在生物化学课程的授课时长(39至280小时,包括总授课时长和所需实验时长)、实验要求(仅71%)以及教师所属部门(17个不同部门,主要是化学系(80%)、生物系(8%)和家政系(4%))方面也存在差异。最受强调的主题是描述性的,如定义、简单结构以及一般中间代谢反应。最不受强调的主题是那些涉及机制性和定量生物化学的内容,如呼吸商(RQ)、酶动力学、脂肪和碳水化合物能量计算以及维生素、酮和代谢中间体的具体结构。生物化学教师与营养教师之间缺乏沟通以及饮食学专业学生在生物化学准备方面的巨大差异令人担忧。
