Finished editing all php files and uploading them. All now work perfectly and look a lot more profesional and logically ordered using LaTex for every equation and giving good general feedback on all questions. Also noticed a few minor errors in some of the questions which have also been fixed. This should be the last time I edit these files, I am now relatively happy with them.

Started work on questions based around calculating errors.

Today I created some more differentiation questions, including questions involing sinx, cosx, e^x, and the product rule.

 

Calculate Mean Height

📥  Uncategorized

Completed a simple statistics question to calculate the mean height of a human population. The data look realistic and the tables appear to be working well on moodle.

After testing my triglyceride MW question in the quiz I found that my calculator was rounding to a different answer. I've managed to come to a compromise, and I've decided I'll use an If statement on compilation to flag any similar issues in future questions.

I've started looking at the "Questions for adapting" sheet, and don't think they're possible to translate verbotem without giving away too many clues.
One approach could be writing a related question which requires the student to rearrange the equation then apply it to some values.

Attempted the quiz of all the chemistry questions, and discovered faults in two of my codes. One was a simple calculation error, and the other was using unrealistic numbers. Fixed both of these codes and added a second part to one of the questions: A simple yes/no question depending on the sign of the previous answer. This required using if/else clauses, and it works for both results.

In todays session I worked on an indices question involving several sequential calculations. I did hit a bit of a problem with wiritng the php file and so will look into this and continue with it next week.

 

Table Generation

📥  Uncategorized

Wrote a function to create a table with an arbitrary number of columns/rows, and with two possible forms of orientation & border. This is now integrated with the statistics code so it should be relatively straightforward to create some questions next week.

I did the quiz and most of it seemed fine.
I have made a differentiation question in the form of: If y=ax^b+cx^d+ex and x=f, calculate dy/dx.
I have to leave slightly early today, but I will continue with this tomorrow. Beth

In todays session I added a hint and worked example to a randomised set of questions already imported into moodle. Following this I fixed some of the errors in a differentiation question where there were multiple answer boxes. I then added a hint and worked example to this question and successfully imported 100 random versions into moodle. I then began work on an indices question involving calculations of number of molecules in E.coli, I will continue with this next week.

I have now tidied up all of my questions and added a size conversion and energy conversion.
