Programming Techniques Assessment (Computer Science) Date : 1-10-18 Strengths/Best Bits : Most of you attempted questions well Good peer assessments Overall the effort from the majority of you has been brilliant ( R1 ) Areas for Improvement : Make sure you put your full name on the assessment paper, One of you did not put there name on the exam paper. Try to use keywords in your answers Try to give examples to help justify and secure your marks   Common SPaG Errors : Write answers in sentences. Make sure you use a capital letter and full stops. Proof read your work.  Lack of Effort/Quality (E/Q): Student A Lack of effort (C2) Student B Lack of effort (C2) No Name Person (C1) Exemplar work (Who, Why?) Highest score : Student C (R2) Student D (R2) Student E (the better behaved one) (R2) Things to Improve On : String handling Procedures and functions SQL

Most of you got 2 out of 3 constructs correct Question 1 (information retrieval) Question 2 (language analysis) Question 3 (structural analysis) Question 4 (critical evaluation) Strengths Most of you stated “constant do not change” Attempted by most of you, who correctly explained it is changing one data type to another Most of you got 2 out of 3 constructs correct When questioning you all in lesson everyone understood the process and how to do it Areas for Improvement State Constant/variable is a container which holds a value [1]   Need to state Can not change while the program is running [1]   Very few of you gave correct examples of casting Int() Str() Float() Chr() Ord() A lot of you are confused about abstraction, decomposition and algorithms as programming constructs ( Sequence Selection and iteration) Very few of you gave examples of the constructs rather then the name. Most pupils didn’t understand the question or answered the question incorrectly, Can you explain why? Common Misconceptions

Mostly correctly answered Question 5 (information retrieval) Question 6 (language analysis) Question 7 (structural analysis) Question 8 (critical evaluation) Strengths Differences most of you stated correctly that a function returns a value and a procedure doesn’t. Some of you answered this correctly Mostly correctly answered Areas for Improvement Most of you struggled to state a similarity, both use structured code, pass parameters to both.      Very few back up statements with facts Very few explained reasons to use procedures, just stated answers Need to learn the different data types and why we use them. Need to re visit SQL in year 11. Common Misconceptions
