Tried, jury-waived, in a so-called jury-of-six proceeding in District Court, Ann Towers was convicted of the crime of operating a motor vehicle while under the influence of alcohol (G. L. c. 90, § 24). In her appeal to this court, she claims that her waiver of the right to trial by jury should be voided because she is not shown to have made it freely and upon adequate knowledge. She claims also that, on the substantive evidence of the alleged crime, she was entitled to, but was denied, a required finding of not guilty, and that the court imprоperly considered extraneous matter in ruling on that issue. We hold that the first claim is justified, *558 the others are not, and so the conviction must be reversed for a new trial.
1. To be сonstitutionally effective, a defendant’s waiver of jury trial must have been made voluntarily and intelligently. See
Patton
v.
United States,
In the case of
Ciummei
v.
Commonwealth,
In the present case, any support for the finding rеsts on the colloquy alone. It was as follows:
The Judge: “Do ypu wish to go jury waived in this case?”
Ms. Towers: “Yah.”
The Judge: “Do you understand what you’re doing?” Ms. Towers: “Yah.”
*559 The Judge: “I just want to make sure you understand all rights, that’s all. You have a right to a jury trial by сonstitution [sic] and it would be up to the jury, not me, to determine if you are guilty or not guilty. The only function that I would have, in the event that you were found guilty, to sentence you. Do you understand thаt?” Ms. Towers: “Yah.”
The Judge: “Have you discussed it with your attorney?”
Ms. Towers: “Yes.”
The Judge: “Okay.”
Although the judge refers to jury trial, there is no description here of what such trial consists of, so as to put it in any meaningful apposition to trial by judge, which also goеs undescribed. The colloquy is instinct with the erroneous suggestion that the judge’s only function in a jury trial is to pronounce sentence if guilt is found. The defendant said yes to having discussed the mаtter with her attorney, who was present, but the content was not of record, see Commonwealth v. Abreu, 391 Mass. 777, 780 (1984). An inquiry about the defendant’s level of education seems a common and significant element of a colloquy but was absent here, and, especially as the crime to be tried involved alcohol, one might have expected the judge to inquire whether the defendant imbibed that day and thus compromised voluntariness. The colloquy has little of the formality or solemnity that should attach to such a procedure. The reference to the constitution appears garbled, as the Commonwealth acknowledges by interpolating “[sz'c].”
It should be emphasized that we do not aim, nor did the Supreme Judicial Court, to describe or hint at a specific form of words that will comprise a minimally adequate colloquy. Rather the question in each instance is whether, on the whole, the record made supports the required finding.
The Commonwealth refers to the colloquy in the
Schofield
case. A majority of our court thought it was inadequate, but the Supreme Judicial Court found it sufficient. See
Commonwealth
v.
Schofield,
Here is the court’s comment on the
Schofield
colloquy in ruling on a companion case,
Commonwealth
v.
Abreu,
Where a judge tries a case and convicts fairly on the merits, there is a natural temptatiоn to palliate the judge’s earlier carelessness in carrying out a threshold procedural protection; but if this is indulged, there will be a progressive lowering or debasing оf the protection actually accorded defendants. The temptation should be resisted, lest we suffer the reproach (paraphrasing Macbeth) that we keep the word of promise to the ear and break it to the hope. 4

2. The defendant contends that the Commonwealth did not prove illicit “operation” of the vеhicle by her to the point where a trier could rationally find guilt, cf.
Commonwealth
v.
Latimore,
The judge could accept the following as a summary of the evidence. When officers arrived at Mоntello and East Nielson Streets, Brockton, in the early morning of December 10, 1988, they found the defendant beside her car, which stood off the road on a sidewalk area in а construction site; the keys were in the ignition and the engine was running. The car showed front end damage. Nearby, parked on Montello Street, was a car with rear end damage; the owner lived across the street and appeared on the scene and spoke to the officers. The defendant “told [one of the officers] she wаs driving the vehicle — she was operating.” From observation and sobriety tests on the spot, the defendant appeared to be intoxicated. We think a trier could infer with reason that the defendant had driven while drunk on Montello Street and struck the parked car. 5
3. At the close of the evidence, the judge said there was enough to conviсt, then inquired why the trial came so late, and was told that it was due to sundry defaults. The defendant suggests that the judge’s view of the evidence may have been colored by his reaсtion to the defaults. We need say no more than that this overlooks the temporal sequence.
Judgment reversed.
Finding set aside.
*562 Appendix 1
The Judge: “Mr. Schofield, my name is Zobel and I’m the Justice of the Superior Cоurt who’s going to be trying this case. And I understand that you want to waive your right to a jury.”
The Defendant: “Yes, your Honor.”
The Judge: “Now, before I can approve of your request to waive your right to a jury, I have to be persuaded that you understand all your rights and are giving them up voluntarily. You understand?”
The Defendant: “Yes.”
The Judge: “Now, I’m going to ask you some questions. If any of my questions are not clear, you just tell me, okay?”
The Defendant: “Yes.” [Then followed preliminary questions concerning Schofield’s age (twenty-seven, at the time of trial), education (ninth grade), occupation (cook), and military service (none)].
The Judge: “You understand that a jury trial means that the twelve people in a jury box decide whether or not you are guilty?”
The Defendant: “Yes, I do.”
The Judge: “And if you give up that right to a jury trial, it means that a judge, in this case, me, I will decide_”
The Defendant: “Yes, I understand.”
The Judge: “ — the case? A jury trial is a very fundamental right. You understand that?”
The Defendant: “Yes, I do.”
The Judge: “That’s why I have to be very sure that you are willing to give up that right аnd are doing it freely and voluntarily. You understand that?”
The Defendant: “Yes.”
The Judge: “Has anyone promised you or offered you anything to make you give up your right to a jury trial?”
The Defendant: “No, I have dоne it on my own. I volunteered.”
The Judge: “Have you discussed this with Mr. Gorman, your lawyer?”
The Defendant: “Yes, I have.”
The Judge: “Okay. And you are satisfied with the advice which Mr. Gorman has given you?”
The Defendant: “Yes. I am.”
The Judge: “All right. I find that Mr. Schofield is fully awarе of his right and that he has knowingly and purposefully and intelligently waived his right to a trial by a jury and I accept the waiver.”

This cannot be dispensed with in our practice. See Commonwealth v. Thetonia, 27 Mass. App. Ct. 783, 783 (1989).
As to the latter, see

Talk in appellate decisions of what is or is not minimally sufficient is not the best guide to practice. Although judges, need not follow verbatim any “model” colloquy, they can take inspiration from the models. See Jury Trial Manual for Criminal Offenses Tried in District Court, Appendix II, Jury Waiver Colloquy (1987); Smith, Criminal Practice and Procedure § 1654 (2d ed. 1983).
In negating the suggestion of a possibility that the defendant’s admission was a figment of her intoxicated state, the Commonwealth is able to distinguish
