3V1275.1

3V1275.01 Computer “rods” (7/20/81) Seeing the trouble she had with the rods always falling over, I asked is a Rods microworld would be easier to manipulate and thus intellectually more accessible to her. So I proceeded to make one, substituting (a later idea) the blinking of numbers in place of partial blanks — that is …

3V1267.1

3V1267.01 Computer-based cuisenaire rods (7/12/81) Peggy enjoyed playing with the Cuisenaire rods during out experiment P181. Either in that one or the next P182, Peggy first accomplished a set of “stairs.” After the end of the experiment, she continued playing with rods and I heard her mention (at a point where she omitted the 3-length …

3V1247.2

3V1247.02 Past tense and conditionals (6/22/81) For the past month or so, Peggy has been forming past tenses in the typical non-standard way — ie. RUN, RUNNED. (I will have to see if I can get her to discuss this in the next session, P181 now) — to get at the question raised by Seigler …

3V1188.1

3V1188.01 Piecemeal discovery from playing with TI BLOCKS (4/24/81) Peggy’s grasp of what she could do with this micro-world has been delightfully piece meal. The first and most striking thing was learning to make the blocks walk. I seem to recall this happened in the first session. The next discovery was the BACK command. It …

3V1185.1

3V1185.01 Computer at home: TI-99 (4/21/81) I finally brought home a TI-99 from the Logo lab. The machine’s storage extension is very flakey and the tape recorder would not work well for the first week or so. Consequently it was hard to program little systems for Peggy. We began using the computer in experiments with …

3V1184.1

3V1184.01 Blocks microworld: Moving Blocks (4/20/81) Peggy has experienced a number of insights in her developing control of the little blocks microworld. The record of her discovery of “BK” is in P169. This is a significant and meaningful operation for her when the block has a forward velocity. In the case “BK” interrupts the velocity …

3V1181.01 Blocks microworld: “Clever little blocks” (4/17/81) Peggy was introduced to computers with P168 and P169. We talked a little today about what she was doing with the computer upstairs. She replied that she was “making the blocks walk.” I asked if she was able to make the blocks turn yet. She replied, “No, they …

3V1171.1

3V1171.01 Letter names versus Meanings: now even “the mommy letter” is blind coded.(4/7/81) In the last experiment, P167, Peggy made a distinction I have observed otherwheres since. When asked the name of any letter, she would reply “D”, no matter what the letter was, no matter what meaning it had for her. For example, she …

3V1169.1

3V1169.01 Recognizing “By” in another context: Asterix book (4/5/81) Peggy asked me to read “Asterix in Britain.” On page 6 (bottom) there appears a balloon with “Attack by Juno” in large capitals. As I was reading near the top of the page, Peggy pointed to “BY” and said, “That says ‘BY’.” Now it appears that …

3V1155.1

3V1155.01 Cuisenaire rods: playing with them after experiments (3/22/81) Guessing games Peggy had used Cuisenaire rods in the immediately previous videotape. Somehow she got hold of them again and I became aware that she was laying them out [Bob had, I think, tried to see if she would build a “stair.”] As she did so, …

3V1122.1

3V112201 Same vs. Different: different animals, same activities (2/17/81) Peggy sat in my lap, playing her animal game (see examples in videotape, e.g. P162). I tired of it and she volunteered, ‘I know…let’s play a different game.’ I agreed enthusiastically, so she got from her toy box two different animals, sat in my lap and …

3V1109.02 Trip to Logo: typical stories (2/14-15/81) Peggy, Robby and I went to MIT after story hour. Danny Moore came to the lab late in the afternoon and I tended Peggy while Robby played with him. What I recall of this time is that Peggy and I went to DSRE for my Spencer Foundation letter, …

3V1102.01 Playing with toys: using animals as manipulatable actors (1/28(81) Recently Peggy has frequently climbed on my lap after dinner, bringing a small collection of animal toys with her. Frequently the horses (Calico and Blue Mane) and Gretchen’s old rabbit and mouse are the main actors. Peggy takes one animal and gives me another, e.g., …
