Tony Bates - who reads and reviews academic literature for fun - offers an overview of recent work on program renewal, a.k.a. curriculum renewal. This is especially relevant in like of the recent emphasis on competencies and skills, which he takes pains to distinguish. "Competency-based learning often aims for 100% proficiency," he writes, but "‘soft skills’ are different... these have no limit." Also, "competencies are job-specific," while "soft skills have high transferability" from one discipline to the next. He then looks at Deesha Chadha's model in more detail, which describes several levels of transferable skills development.
