What is a lesson plan in the Official Letter 5512 format?
A lesson plan in the Official Letter 5512 format is a teaching plan written in the structure of Official Letter 5512: a section of aims, a section of teaching equipment and materials, then the teaching process made of four activities in sequence: opening, forming new knowledge, practice and application.
In EduFlow every activity has its own minutes, linked learning requirements and four parts: aims, content, outputs and how it is organised. The organisation part goes through four steps: handing over the task, carrying it out, reporting and discussing, then concluding.
The subject, grade, chapter, topic and learning requirements come from the GDPT 2018 curriculum framework that ships with the app and is read on your computer, with no network. Each plan is one fixed 45-minute lesson; the minutes of the activities must add up to exactly 45.
Writing by hand, using ChatGPT, and using EduFlow
| Criterion | By hand | ChatGPT or a general tool | EduFlow |
|---|---|---|---|
| The Official Letter 5512 structure | You build the frame yourself from the template you use. | You paste the structure into your prompt and check whether every section is there. | A fixed structure: aims, equipment and materials, and a process with four activities in order. Gate P6 checks that the required sections are present. |
| Curriculum data | You look up the framework and copy the learning requirements. | You paste the chapter, topic and learning requirements into your prompt. | Subject, grade, chapter, topic and learning requirements come from the GDPT 2018 framework built into the app, read on your computer. Each activity links up to six requirements. |
| Total time of the lesson | You add up the minutes of the activities yourself. | You ask it to split the minutes and add them up again yourself. | A fixed 45-minute lesson; gate P7 checks that the minutes add up to exactly 45, and the total line updates as you edit. |
| Information about the author | It stays in your own file. | You decide what to write into the conversation. | School, department and teacher name are only printed in the header and are never sent to AI. The lesson name and your notes are sent. |
| Who approves the plan | You review and approve it by your school's process. | You review the content and record the approval yourself. | The plan stays a proposal until you press approve; at the K-12 level that is the last step. Each warning needs its own confirmation. |
| The file for your records | You write it directly in a word processor. | It returns text that you paste into a file and lay out. | Export to DOCX or PDF. An unapproved plan can still be exported, with a DÙNG THỬ (trial) watermark. |

The four activities of the plan
A lesson plan in EduFlow is one 45-minute lesson with the four activities below, in this order. On the plan screen each activity is an editable block with its minutes, linked learning requirements and the four parts a, b, c, d.
- Opening: Creates a situation that brings students into the lesson, linked to what they already know.
- Forming new knowledge: Students work on the main content of the topic and produce something concrete.
- Practice: Students consolidate through tasks with clear outputs and a clear way to carry them out.
- Application: Students use what they learned in a new situation.
The plan gates and the review
In the export step, the gate table gives each gate code, the units checked, the violations and the result. A gate that checked 0 units does not count as passed: the app reports a gate error. A missing required section or a wrong total of minutes is a blocking violation, to fix in the plan step and save.
- P6: The plan has the full Official Letter 5512 structure.
- P7: The total minutes equal the number of lessons times 45.
- P11: Each activity is anchored to a learning requirement; an unanchored one is a warning, fixed by editing or by confirming that line.
- P10: A teacher has approved the plan; it reads as waiting for approval until you press approve.
- Semantic review: A separate card scores eight criteria, each as passed or not passed with a note. It is only a suggestion for the approver and locks nothing.
- Cost: Before AI runs, the app shows a cost estimate box; cancel and no job is created and nothing is charged. How cost is calculated is explained on EduFlow pricing.
Write an Official Letter 5512 lesson plan with EduFlow
These steps follow the lesson plan screen of the app; the linked guide covers every button.
- Choose to write a lesson and pick the lesson plan type. Click write a lesson on the home screen, in the sidebar, or new lesson inside a K-12 project, then choose the lesson plan type. Write a lesson plan (Official Letter 5512)
- Pick the subject, grade, chapter, topic and lesson name. Choose from the GDPT 2018 framework built into the app. The lesson name is at most 120 characters and is sent to AI as the focus of the lesson, so do not write student names or personal details in it. Write a lesson plan (Official Letter 5512)
- Fill in the plan header. Fill in school, department and teacher name (never sent to AI) and, if you like, your notes to AI (sent as written). Every change saves itself after about a second. Write a lesson plan (Official Letter 5512)
- Let AI write the four activities. Click generate, read the estimated cost in the dialog, then run it. It needs a network connection; when it finishes, the screen opens the plan step. Write a lesson plan (Official Letter 5512)
- Read the gate warnings and edit. Edit each activity, check that the total reads exactly 45 minutes, then save so the app runs the gates again. Each warning has its own confirm button, with no confirm-all button. Write a lesson plan (Official Letter 5512)
- Approve and export DOCX or PDF. When no blocking violation is left and you have confirmed the warnings, approve, then export DOCX or PDF. An unapproved plan can still be exported, with a DÙNG THỬ (trial) watermark. Write a lesson plan (Official Letter 5512)
What EduFlow does not do yet
- Some subjects: the lesson dialog lists only the subjects of the GDPT 2018 framework that ships with the app. Literature, Vietnamese language, Music, Art and Experiential activities are not there; they exist only in the full pack, planned after the first release, with no date.
- A lesson plan template of your own school: not available. EduFlow builds one fixed Official Letter 5512 structure and cannot yet load a school sample plan to build from it.
- A library of sample lesson plans by subject and grade, and a school logo in the plan header: not available. The header holds only school, department and teacher name for now.
- AI writes a proposal only: you check, edit and approve it before using it in class. Each plan is one 45-minute lesson; generating a plan needs a network connection.
