I have seen the term "Job-Embedded" in proffessional development papers, but I didnt find any well description of its meaning, what does it mean?
@Arrowfar suggested it, and I just searched for "job-embedded" (with quotes) on both Google and Wikipedia - interesting results...
I am not sure job-embedded is connected (aside from sounding similar) to job embeddedness as defined by Wikipedia. However, what I do see is a very stable use of "job-embedded professional development", from which I dare to hazard a guess that it's some kind of training program that teachers (this is what I see the most) undergo while continuing their normal job activities. What exactly it consists of, is not clear and I don't want to speculate.
Essentially it appears to be "on the job training" of sorts, specific to teachers.
First of all, I had never encountered this term "job-embedded" before I read your question, though the term on-the-job training (OJT) wasn't new for me. My first guess when I read the title before opening this question was that it would be about something "embedded in the job". Judging from the PDF I found (see below), I think "embedded in the job" isn't very far off.
From the PDF file (titled Job-Embedded Professional Development: What It Is, Who Is Responsible, and How to Get It Done Well),
What Is Job-Embedded Professional Development?
Job-embedded professional development (JEPD) refers to teacher learning that is grounded in day-to-day teaching practice and is designed to enhance teachers’ content-specific instructional practices with the intent of improving student learning (Darling-Hammond & McLaughlin, 1995; Hirsh, 2009). It is primarily school or classroom based and is integrated into the workday, consisting of teachers assessing and finding solutions for authentic and immediate problems of practice as part of a cycle of continuous improvement (Hawley & Valli, 1999; National Staff Development Council, 2010). JEPD is a shared, ongoing process that is locally rooted and makes a direct connection between learning and application in daily practice, thereby requiring active teacher involvement in cooperative, inquiry-based work (Hawley & Valli, 1999). High-quality JEPD also is aligned with state standards for student academic achievement and any related local educational agency and school improvement goals (Hirsh, 2009).
In my humble opinion, this seems like teacher's jargon. It's also worth noting that searching for
"job-embedded" on Google returns only 381 results. And the PDF I linked to in this answer is probably the best source that clarifies what job-embedded is all about.
