The class sees a source on the wall, at least up close. Ghi chús alone are not enough.
You have a survey. Today a line the class sees. A source is honesty. Under a chart, a photo, a diagram one small line: who, what, when, or “own photo”, “an anonymous poll of 12 votes”. Type smaller, but with contrast. Not grey fog.
Imagine a chart with no line. The teacher: where from. A shrug. A figure. Decoration. Trust falls. Under 12 km “odometer, 8 May.” Under the chart “a poll of 12 votes, the class, May”. The teacher. Trust. The line small. Visible.
Rule: a text box under the picture. Size 14–18, but contrast almost black on white. Not into notes as the only place. The class sees the source, at least up close. From the back it is enough to know it is there.
Do not write an email into a source. Do not write a link to a private chat. A text box under the picture, size 16 plus, contrast. Ghi chús alone are not enough. The class sees the source. Type smaller, but with contrast. Not grey fog. A source visible.
Klára left a chart with no line. The teacher: where from. A shrug. The figure looked like decoration. Marek under 12 km wrote “odometer, 8 May.” Under the chart “a poll of 12 votes, the class, May”. The teacher. Trust. In the evening Klára added a box under the chart and made it bigger from ten to sixteen, because grey fog vanished. She said she had it in notes. The class does not see notes. Today a line on the wall. She added a box under the chart and made it sixteen. Grey ten vanished. Dad held the account. The teacher hit where from. Up close the line could be read. From the back you could see it was there. Grey ten no more.
Up close the line must be readable. From the back it is enough to see it is there. Size 16 plus if it vanishes. Do not shrink it for looks.
One line under a picture, contrast, no email
Under every picture and chart insert a text box. One line. Contrast. Not fog. Not an email. Own / a poll / school / a date.
Present (F5). Up close do you read the line? From the back do you know it is there? Size 16 plus if it vanishes. Make it bigger. Do not shrink it for looks.
A slide with no line at someone else’s picture: delete the picture, or add a source. You have no source? The picture off. Honesty. Ghi chús may hold a longer link. The wall holds a short line.
Grey type 10 on a grey strip dies like contrast in Chuẩn bị. It holds here too. Under every picture and chart one line. Own, a poll, school, a date. Not an email. Present (F5) up close: can the line be read? From the back do you know it is there? You have no source? The picture off. Full stop. Size 16 plus, contrast almost black on white, so the line at least lights up from the back.
Wrong: a chart, no line, in notes “from the net”. The teacher does not believe. A figure decoration.
Right: Marek. A line under. Klára after adding the same, contrast, 16.
An example: “own photo, a chain, 8 May.” “textbook p. 42, the teacher allowed.” “an anonymous poll of 12 votes, 12 May.” Full stop. No email. No chat. “own photo, a chain, 8 May.” carries trust. A figure with no line is decoration. Grey fog size 10 no. “textbook p. 42, the teacher allowed.” carries. A link to chat does not. Full stop. Under 12 km an odometer and a date. Under the chart a poll of 12 votes and May.
Do not write an email into a source. Do not write a link to a private chat. Trường words. Own. A textbook. A poll. A date. Full stop.
Four things you will build in this course
The course has four small projects. You do not have to do them all at once. Today you add only this:
🎯 A hobby in 5 slides
Five slides about something you like doing. One sentence about what it is. No paragraphs from your notebook.
Hobby: under a photo “own photo” and a date, not a link to a shop.
📚 A report
Eight slides for school: a start, three proofs, an end. The title on every slide is a sentence, not “Slide 3”.
Report: under a diagram “own shapes” or a textbook with permission.
📊 Survey results
A chart from a table (not a screenshot from chat) and under it where the numbers come from.
Survey: under the chart a vote count and a date. Without that a figure lies with trust.
⚖️ A defence
You say one sentence, show proof, answer “and what if…”. If you do not know, you say I don’t know.
Defence: a panel points at a number. The line answers where from.
Add a line under every picture and chart
A text box. One line. Contrast. Present. What has no source, delete.
-
Under every picture and chart insert a text box. One source line. Contrast. Not fog. Not an email. Own / a poll / school. A parent’s account.
-
Present (F5). Up close do you read the line? From the back do you know it is there? Size 16 plus if it vanishes. Make it bigger.
-
In PowerPoint almost the same: a text box under the object, contrast, size. A slide with no line at someone else’s picture: delete the picture, or add a source. You have no source? The picture off.
-
Ghi chús may hold longer info. The wall holds a short line. Both. Not only notes.
-
Drive a tick. The workshop ends when every picture and chart has a visible line. The finale tomorrow. Today lines.
Decoration, or trust
A figure with no line is decoration. A line makes trust.
-
Under every chart write a count and a date, or delete the chart.
-
Under a photo “own photo” or a concrete school source.
-
Make grey ten bigger to contrast 16.
Now you 💪
- Under every picture and chart is one contrast line where from.
- In the line there is no email or a link to chat.
- Up close I read the line. From the back I know it is there.
Done when: The source is on the wall under the picture. A figure with no line is gone. Trust holds.
What to take from this lesson
- Under a picture and a chart one line where from.
- Ghi chús alone are not enough. The class should see the source.
- Contrast. Not grey fog size 10.
- With no source delete the picture.
- No email in a source.
- Têns in the examples (Klára, Marek) are made up. Do not put your number, email or photo on a slide.
