||Herron developed a model
which classified inquiries on a scale of 0 (Confirmation/Verification)
to 3 (Open Inquiry) depending on how much teacher structure is supplied
and whether there is an already existing solution to the problem or question.
I like this model because it ties in with my beliefs about the need for
scaffolded/guided inquiry when students (of any age) are new to inquiry.

Modified Herron's Model
I have made some modification to Herron's model (see table below). Firstly I have renumbered the levels as I feel that naming it 0 implies it is not inquiry. It is certainly very low-level inquiry but I believe it is still has a place at times. Secondly, I have restructured the table to make the desired outcome clearer i.e. ticks for student designed/owned elements rather than for teacher designed/owned elements.
I have changed the second level (Herron's level 1) to allow for either a student-generated question to which there is a pre-existing solution (not known to the students) or for an unknown solution to a teacher-generated question. This is because student-generated questions can often have pre-existing solutions. If we include among our definitions of inquiry: "Inquiry" is defined as "a seeking for truth, information, or knowledge - seeking information by questioning." (www.thirteen.org/edonline/concept2class/inquiry/), "Inquiry is a systematic investigation or study into a worthy question, issue, problem or idea." (www.galileo.org/inquiry-what.html) and especially: “Through the process of inquiry, individuals construct much of their understanding of the natural and human-designed worlds.” (www.thirteen.org/edonline/concept2class/inquiry/), then we must allow for that fact that some student-generated inquiries will have a pre-existing solution.
I have also changed the third level (Herron's level 2) to include either a student-generated problem or student- designed/selected procedure. This is because I feel that students are often able to generate their own problems before they are ready to independently design and/or select all the procedures they will use and that students. I believe having an either/or situation more actually reflects what can happen in classrooms. I have renamed the final level Independent Inquiry as I feel this more accurately describes the level.
Table modified from http://edweb.sdsu.edu/wip/four_levels.htm
1. Confirmation - students answer a teacher-presented question through a prescribed procedure when the results are known in advance to the teacher but not necessarily the students.
2. Structured Inquiry - students investigate through a prescribed procedure and EITHER there is a teacher-presented question (usually open-ended) but the answer is not known in advance and could vary from student to student OR there is a student-generated question where the results are known in advance to the teacher but not to the students.
3. Guided Inquiry - The solution is not already existing/known in advance and could vary from student to student. Students EITHER investigate a teacher-presented question (usually open-ended) using student designed/selected procedures OR investigate questions that are student formulated (usually open-ended) through a prescribed procedure (some parts of the procedure may be student designed/selected).
4. Independent Inquiry - students investigate questions that are student formulated (usually open-ended) through student designed/selected procedures. The solution is not known in advance and could vary from student to student. Ownership of all aspects of the inquiry belongs to the student.
