Levels of inquiry functioning that describe the performance on each individual attempt

	Level	Use of task feedback	Variable coordination	Variable isolation	Succes
1	Reiteration of magnitudes between attempts (Repeating same conditions from last attempt)	No	No	No	No
2	Basic adjustment without magnitude coordination nor previous information coordination.	No	No	No	No
3	Basic adjustment with magnitude but without coordination with previous information coordination.	No	Yes	No	No
4	Basic adjustment isolating variables but with-out previous information coordination.	No	Yes	Yes	No
5	Adjustments without magnitude coordination but coordinated with previous information.	Yes	No	Yes	No
6	Adjustment with multiple variables with magnitude and previous information coordination and partially attuned with the goal.	Yes	Yes	No	No
7	Systematic adjustment isolating variables and with previous information coordination and partially attuned with the goal.	Yes	Yes	Yes	No
8	Adjustments with multiple variables and with magnitude and previous feedback coordination attuned with the goal.	Yes	Yes	No	Yes
9	Adjustment with variable isolation and with previous information coordination. Goal reached.	Yes	Yes	Yes	Yes
