Activity Summary A TRACS exercise for database queries. A set of queries suitable for national 4 and national 5. Number of Lessons An introductory lesson with pupils attempting simple examples. A second lesson to present complex sort / search and calculated / derived data. PLAN...
Activity Summary The attached resources demonstrate TRACS for expressions at N4/5 level, and focus on the order in which a language evaluates an expression. Pupils can be guided through the process, allowing them to use the PICCLLES guide to carry out expressions in the correct order. Suggested time allocation These tasks...
Summary of Approach The process a computer goes through when executing a section of code is manually stepped through by the learner in order to understand how it will work and what the expected output should be. Keypoints Just showing a visualisation of a piece of...
Summary of Technique Pupils use a paper-based TRACS model to trace the processing of a database query. Pupils annotate the model to indicate the sequence of the operations and the effect of each of the operations on the results of the query. The activity is based...
Summary of Technique Office mix TRACS for expressions is a technique for analysing the expressions in code. This could be as simple as the expression 4+5, to a complex expression such as (INT(RND*23)+1)>ROUND(a,3) OR b<j*r. The approach uses annotation to outline the order of evaluation of...
