First Program — Scratch for ages 5–9

Nine Scratch blocks, three sessions of about twenty-five minutes, and one small program a child of five to nine builds themselves. Written for the parent sitting beside them: what to click, what they will get stuck on, what to say when it goes wrong, and when to keep your hands off the mouse.

First Program — Scratch for ages 5–9

课程概述

This is the sequence used with a five-year-old who had already outgrown Scratch Jr, taught again with an eight-year-old, and it works because most of it is not teaching. The first twenty minutes are free play. No instructions at all. The child drags blocks and makes nonsense happen, and that is deliberate — a child who has already found out that blocks snap together and make things move does not need to be told what a block is. In the recorded session the five-year-old found the arithmetic blocks on her own, including negative numbers, ahead of anything she had been taught at school. After that, the child builds one thing: a character that jumps when you press the space bar, makes a pop as it goes, and then asks the child their name and greets them by it. Along the way there is one discovery that carries the whole segment, and it is a real one. Put the sound block inside the loop and it fires ten times, a horrible stutter. Put it above the loop and it fires once. Nobody explains this in advance. The child hears the difference, moves one block, and hears it again. Three sessions. The child chooses the character and what it says. Every written page is addressed to you, the adult in the chair, not to the child — they never read a word of it. Your job is to keep it moving, not to steer it, and to stop when they are done rather than when the lesson is.

  1. 01 Let Them Play First
    3 节课程·52m

    You will be tempted to start teaching in minute one. Do not. The free play is the lesson. It builds the one thing a child of this age needs before instruction is any use at all: the knowledge that…

  2. 02 The Jump, and the Sound in the Wrong Place
    3 节课程·53m

    The jump is built from four blocks and it is genuinely satisfying, so this is the session most children stay with longest. The sound goes in the wrong place first. Do not warn them. Let it stutter,…

  3. 03 The Sprite That Knows Your Name
    3 节课程·55m

    This is the part children remember, because the computer says their name. Two new blocks, one of which has to be dropped inside a gap in another block, which is fiddly with a mouse and worse with a…

Programming for the Exam — Python Answers That Score
Intermediate Programming for the Exam — Python Answers That Score The programming half of the paper, taught at exam pitch. Pseudocode translated both ways, because the mark scheme is written in a notation nobody practises. Trace tables done column by column, including the ones with a loop and a condition inside it. Linear and binary search, bubble and insertion sort, what each costs and the comparison questions boards love. Validation against verification, and the boundary test data everybody forgets. Procedures against functions, and a systematic method for finding your own error with four minutes left.

A fifth you should not have handed over. You finish with real work done and a page of your own numbers you can show someone.
