Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? In Tough's 1971 study of sixty-six adults across seven occupational categories, all but one interviewee had conducted a learning project in the previous year, fewer than one per cent of projects were undertaken for credit, and 68% were self-planned. → Percy 1994 q2 i? Every occupational category in Tough's 1971 sample that included women spent fewer hours on learning projects than the other categories. → Percy 1994 (2)

q2 · i? · review · r2

Tough's 1970 study, reported in The Adult's Learning Projects, interviewed sixty-six adults drawn from seven occupational categories using intensive structured interviews with probing and prompt sheets; the review reports near-universal project participation and under 1% undertaken for credit, with "the majority (68%) of projects were self-planned".

"All but one of the interviewees had conducted a learning project in the previous year, and less than one per cent of all the learning projects was undertaken for credit."

q2 · i? · review · r2

Across the seven occupational groups, total hours devoted to learning projects differed by group (professors highest, mothers lowest in hours); the review reports that every category including women logged fewer hours, a finding Tough did not pursue.

"A significant finding of the research was that every category which included women spent less hours engaged inlearningprojects."
