Session 2. The Phone as a Document Camera, and Tidy Files
Objective. Set up a phone on a simple stand to show a page to the whole class, and name and store files so that they can be found quickly.
Showing one pupil's page to thirty-five others used to mean copying it on the board or passing the notebook round. A phone on a simple stand can do it in seconds, but only if the picture is steady, sharp and complete, and only if you can find the file again next month. This page looks at the geometry of a good shot and at the small file habits that stop a phone from becoming a drawer of lost photos.
Key ideas
Why show the real page
- A document camera shows a textbook page, a pupil's notebook, a drawing or a small object to everyone at once, so you do not copy it onto the board.
- A phone with a decent camera can do this job if you can fix it above the page. It still needs a display from session 1.
- Good uses: model a worked example in real time, compare two pupils' solutions, show a map or diagram, read a short text with a finger or pencil pointing along.
Set up the shot
- Build a stand from what you have: a pile of books, two cups, a folded card or a small box. The phone must be steady, straight above the page and parallel to the desk.
- Frame the whole page with a small margin, in wide (landscape) orientation. Switch off the flash, tap the text to focus, and let light come from the side.
- Test before the lesson: put a page under the phone and look at the big screen from the back row. If you can read your own handwriting there, pupils can too.
Photograph pupils' work with care
- Show the work, not the child: no faces, and cover the name with a slip of paper. Follow your school's rules and ask permission where they require it.
- Ask the pupil first. Many are proud, but some do not want their mistakes shown; offer to show a good example instead.
- After the lesson move useful photos to the school folder and delete the rest from the phone gallery. Do not post to open chat groups.
Names, folders and a second copy
- Use one pattern for every file: date with the year first, class, subject, topic and type, for example 2027-03-03_5A_maths_fractions_worksheet.
- Keep one folder per class and term, with the same sub-folders each time (plans, slides, worksheets, photos, marks). Avoid names like 'new' or 'final2'.
- Keep a second copy in another place, such as a USB stick or the school computer, and a printout of the one file you cannot lose today.
From the page to a file you can find
What the camera sees
A camera sees a cone, so the higher it is above the page, the more of the desk it takes in and the smaller your handwriting appears. Place the phone just high enough to fit the whole page and a small margin, and no higher. Keep the back of the phone parallel to the desk; if it is tilted, the page looks like a trapezium and the lines slope.
Light matters as much as height. A window or lamp at the side lights the page evenly and keeps your hand out of the way, while a flash on glossy paper creates a white patch. Let the phone focus on the text, wait a second before you speak, and always judge the picture on the big screen from the back row.
Files you can find in ten seconds
A phone gallery sorts by the moment of capture, which is no help when you need 'the fraction worksheet from March'. Give each kept file a name that starts with the date written year first, then class, subject and topic. Because the year comes first, a list sorts in time order without any effort.
Decide where files live before you create them: a folder for each class and term, with the same few sub-folders every time. Keep a second copy somewhere else, such as a USB stick or a school computer, because phones are lost and broken. After each lesson move the photos you want into the folder and delete the rest, which also protects the pupils in them.
Examples from the classroom
A pupil's clever solution
Scene. Aziz teaches Grade 5 mathematics in Tashkent to 38 pupils. A pupil solves a fraction problem in a way nobody expected. Aziz builds a stand from four textbooks and a cup, puts the notebook under his phone with the window on his left, and shows the page on the TV. The page is sharp, with no shadow, and he points with a pencil. Pupils explain each step in turn.
Insight. A steady phone and side light let the class study real work instead of listening to a description of it.
Reading a poem together
Scene. Dilnoza teaches Grade 3 in Samarkand and has 28 textbooks for 35 pupils. She places the poem under the phone and follows each line with a pencil while pupils read aloud. For the last verse she covers the words with a strip of paper and the pupils recall them. The printed copy stays in the lesson box in case the phone battery is low.
Insight. One shared page serves the whole class when books are short, and a printed copy protects the lesson.
From 1,200 photos to three folders
Scene. Malika teaches Grade 6 in Fergana and has about 1,200 photos named IMG_ followed by a number. One Sunday she creates a folder for each class and term, moves the 40 useful photos, and renames them with date, class and topic. She copies the folders to the school computer and deletes the rest. In March she finds last year's water-cycle worksheet in under ten seconds.
Insight. A name pattern, a folder plan and a second copy turn a pile of pictures into a reusable library.
Common pitfalls
- Holding the phone in one hand over the page, which causes shadows, tilt and blur.
- Showing a pupil's name and face when the work alone would do.
- Keeping the only copy of an important file on one phone.
- Names such as 'new' or 'final2' that nobody can decode after a week.
Photo Problems and the File-Name Sort
- Photo problem cards (10 min): in pairs, read the six cards that describe poor pictures of a page. For each, write the cause and one fix. If phones are available, test two of your fixes on a real page.
- Design a stand (10 min): sketch or build a stand from objects in the room (books, cups, card, a box). A good stand is stable, holds the phone straight above the page and leaves both hands free. Write your measurements, such as the height of the pile.
- File-name sort (10 min): sort the ten file-name cards into GOOD and POOR. Rewrite each poor name with the date, class, subject and topic pattern. Then sketch a folder tree for one class for one term.
- Agree a pattern (5 min): as a group, vote for one naming pattern and one folder layout that everyone can use, so that colleagues can find shared files too.
Your facilitator will guide you through this activity in the session.
Questions to discuss
- Which photo problem happens most often with your hands and your light, and what is the quickest fix?
- What would you do if there is no phone, no stand or no display? How would you show a page to everyone?
- What is your rule for pupils' names and faces in photos?
Reflect
- Which page, drawing or object would you show to the whole class this week if you could?
- How long does it take you to find last term's best worksheet right now?
- Where is your second copy of your most important file?
Try it tomorrow
- Make a stand from books or cups and test it with one page, checking the result on the big screen from the back row.
- Choose one name pattern and rename the ten files you use most.
- Copy your most important folder to a second place today.
