C
[解析] 词语搭配题。be engaged in意为“从事于,忙于”,例如:Engaged in conversation, they did not see me. 根据原文意思:高等教育的人文价值观念鼓励学生积极培养自我发展的能力,选项C engaged在语意与结构上均符合题意,故选C。选项A consist in意为“存在于”,例如:The beauty of air travel consists in its speed and ease. consist的常见用法还有:consist of(由…组成,构成),consist with(与…一致,符合);选项B dealt和选项D worked均不能与in连用。
