Acronyms and Abbreviations, dont you just love them? I occassionally get asked... What does PDP really mean? (Personal Development Planning)
The Higher Education Academy has a rather good summary: http://www.heacademy.ac.uk/ourwork/learning/pdp they also provide some case study examples (see links at the bottom of the page) showing how other persons have implemented PDP. E.g. http://www.heacademy.ac.uk/resources/detail/id91_a_series_of_case_studies
These range from purely factual information gathering (e.g. for CVs) to the more subjective student centred reflective journals. Reflective journal information can be used as evidence in, for example, the ‘further information’ sections of job application forms – what the students did, achieved and skills they used in their projects; or perhaps even their labwork/fieldwork experiences.
