Today’s Notes: Charlotte Notes 16th January 2019

Exam technique revision lesson. Charlotte to complete essay question planned in the notes below for next lesson:

Charlotte Notes 12-12-18

Theory lesson on Application Software – Charlotte felt that this area had many gaps so we covered each section in detail.

Notes are linked in the revision section for Application Software below.

Following on from last lesson, we focused on exam technique today using the exam board exemplar questions.

Pseudocode is showing a clear improvement, and the more we practice, the more accurate the logic will become.

I have suggested that Charlotte watches the tutorial video below on linked lists to extend from the questions that we covered today.

We focused on theory work from types of processor today (see revision list below). It appears that Charlotte has some knowledge gaps in this area, so we have been using Doodle Notes to bring her up to speed on these quickly.

Once these are completed, we will use past papers to apply the knowledge and work on exam technique.

We began to look at revision of internal hardware today. This has led to the identification of some significant gaps in her knowledge. To address this, I have added a list of OCR topics below to alow us to monitor progress and we are looking through the Structure of The CPU from foundations.

Continued to use C to create a worked example of a queue.

It would be worth looking at the syntax of loops:

FOR:

for ( int i = 0; i < 10; i++ ) {
  printf("d%", i);
}

WHILE:

while (true) 
{
    take_turn(player1);
    take_turn(player2);
}

DO WHILE:

do {
      printf( "Hello, world!\n" );
  } while ( x != 0 );

We were using the online C editor this week – it should allow you to create most of the required code: https://repl.it/repls/ForthrightClearcutDigit

Lesson recording:

In our first lesson we discussed Charlotte’s progress so far in college and identified that programming an algorithms have become a pinch point. With this in mind, we started today with a focus on writing pseudocode with more confidence.

The link to the official OCR pseudocode Guide is here.
