Abstract: A system manages education, career planning, workforce mobility for students and workers includes a database configured to store a code corresponding to a classification of a course. The course can include a single learning unit or any combination of learning units. The database also stores learner information including at least one code corresponding to the classified course and one code corresponding to assessment information for the classified course. An interface is configured to suggest recommended courses based on the learner information.

Abstract: A system for managing course content for a course includes a database configured to store course content. Course content includes problem-solving learning environments and design (PSLED) blocks. An interface is configured to provide information from a PSLED block for a student. An input and output module are configured to receive and send input regarding at least one of the PSLED blocks stored in the database. An evaluation module is configured to evaluate the student based on assessment requirements in at least one of the PSLED blocks stored in the database and based on the assessment data. A mapping module is configured for analyzing and mapping attributes between PSLED blocks stored in the database, the attributes including at least one of equivalency of instructional units, equivalency of standards of learning and practice, equivalency of micro-certificates, and equivalency of micro-credentials.
