Hint

-A line representing a function slanting upwards to the right is increasing, since as you increase -the inputs, the outputs increase as well. -

- If the line is horizontal then the outputs don't change -so the function is constant. -

-When you zoom in on most functions they look like straight lines. (The functions for which -this works are called differentiable functions --- there ARE functions which are not differentiable, -but we'll get to those later.) In any case you can tell whether a function is increasing or -decreasing by zooming in and determining whether the straight line is increasing or decreasing. -

-This means that the study of (differentiable) functions is largely a matter of understanding what -happens with straight line (or linear) functions. -

-

Remark on hints

-WeBWorK hints may or may not be helpful. - -Remember that WeBWorK's primary mission is to tell you whether your answer is correct. Programming -a computer to do this is hard enough, programming a computer to accurately understand why you -getting the wrong answer and to offer effective help is much harder. -

Standard example: $EBOLD This covers what you need to know to ask the majority of the questions you would want to ask in a calculus course. Problems with text answers, numerical answers and answers involving expressions are covered. -$PAR -$BBOLD 3. Simple multiple choice example: $EBOLD Uses lists(arrays) to implement a multiple choice question. -$PAR -$BBOLD 4.

True/false example: $EBOLD -$PAR -$BBOLD 7. Pop-up true/false example: $EBOLD Answers are chosen from a pop-up list. -$PAR -$BBOLD 8. On-the-fly graphics example 1: $EBOLD The graphs are regenerated each time you press the submit button -$PAR -$BBOLD 9. On-the-fly-graphics example 2: $EBOLD -- Adds some randomization to the first example. -$PAR -$BBOLD 10. Static graphics example: $EBOLD Presents graphs created on a separate application (e.g. Mathematica) and saved. -$PAR -$BBOLD 11. Hermite graph example: $EBOLD A particularly useful way of generating predictable graphs by specifying the value and first derivative of a function at each point. Piecewise linear graphs are also included in this example. -$PAR -$BBOLD 12. HTML links example: $EBOLD Shows how to link other web resources to your WeBWorK problem. -$PAR -$BBOLD 13. JavaScript example 1: $EBOLD An example which takes advantage of this interactive media! This one requires students to calculate the derivative of a function from the definition. -$PAR -$BBOLD 14. JavaScript example 2: $EBOLD A variant of the previous example that generates the example function as a cubic spline so that students can't read the javaScript code to find out the answer. -$PAR -$BBOLD 15. Vector field example $EBOLD Generates vector field graphs on-the-fly. -$PAR -$BBOLD 16. Conditional question example: $EBOLD Illustrates how you can create a problem which first asks an easy question, and once that has been answered correctly, follows up with a more involved question on the same material. -$PAR -$BBOLD 17 Java applet example: $EBOLD A preliminary example of how to include Java applets in WeBWorK problems. -$HR -END_TEXT - -################## -# EDIT ABOVE HERE -################## -BEGIN_TEXT -The primary purpose of WeBWorK is to let you know if you are getting the right answer or to alert -you if you get the wrong answer.

For example with -${LQ}MathJax${RQ} you can control the size of equations, have access -to accessibility options, etc. The ${LQ}Grades${RQ} page -shows your scores on the various assignments (but there is nothing -much to show at this point). -$PAR - -Links to your homework assignments are also listed in the ${LQ}Sets${RQ} -panel so you can quickly switch to another assignment. -$PAR - -\{ -#The ${LQ}Report Bugs${RQ} button is for reporting bugs in the WeBWorK -#System itself to the developers WeBWorK. It is unlikely that -#you will need to use that yourself. If you are having difficulty with -#WeBWorK, you should contact your professor using the ${LQ}Email -#Instructor${RQ} button instead. This should be available on nearly -#every page, so you always have a quick way to reach your professor. -#$PAR -\} - -The data in the panel at the top of the page tells you where you -are in WeBWorK's hierarchy of pages, but you can ignore that for the -most part. There is an additional logout button at the far right, -however, that you will need to use when you are done using $WW (don't -press it yet). -$PAR - -\{ -#The yellow question mark icon is a ${LQ}Help${RQ} -#button for system documentation, but there is not much of that -#available at the moment. -#$PAR -\} - -The main information on this page is located in the large panel -to the left. It shows the status of the problems in this assignment, -and your score on the set so far. Since you haven't yet tried any of -the problems, your score is zero, but after you work on some of them, -the number of attempts and the score will reflect the work you have -done. -$PAR -Near the bottom is a link that allows you to download a pdf ${LQ}hardcopy${RQ} -version of your -whole assignment which you can print out. This allows you to work on -the assignment without having to be connected to $WW. -$PAR -Also near the bottom of this and every $WW page there is an -${LQ}Email instructor${RQ} link that you can use to send email to -your instructor. That email, in addition to what ever you write, will -contain information on whatever page you are on so, e.g. if you are -working on a problem, your instructor will know what problem it is. - -$PAR -Each problem number is a link to that problem in the homework set. -You can click on one to get to any specific problem. To begin the -orientation assignment, click on the link for Problem 1. When you are -done working, be sure to dismiss your connection to the server by -clicking on ${LQ}Log Out${RQ}, so that no one else can gain access to -your account. -$PAR - - -END_TEXT - -} - -ENDDOCUMENT(); # This should be the last executable line in the problem. diff --git a/lib/WeBWorK/Utils/Rendering.pm b/lib/WeBWorK/Utils/Rendering.pm index 474936d49a..3869670e5b 100644 --- a/lib/WeBWorK/Utils/Rendering.pm +++ b/lib/WeBWorK/Utils/Rendering.pm @@ -67,14 +67,15 @@ sub constructPGOptions ($ce, $user, $set, $problem, $psvn, $formFields, $transla $options{problemSeed} = $problem->problem_seed; # Display information - $options{displayMode} = $translationOptions->{displayMode}; - $options{showHints} = $translationOptions->{showHints}; - $options{showSolutions} = $translationOptions->{showSolutions}; - $options{forceScaffoldsOpen} = $translationOptions->{forceScaffoldsOpen}; - $options{setOpen} = time > $set->open_date; - $options{pastDue} = time > $set->due_date; - $options{answersAvailable} = time > $set->answer_date; - $options{refreshMath2img} = $translationOptions->{refreshMath2img}; + $options{displayMode} = $translationOptions->{displayMode}; + $options{showHints} = $translationOptions->{showHints}; + $options{showSolutions} = $translationOptions->{showSolutions}; + $options{forceScaffoldsOpen} = $translationOptions->{forceScaffoldsOpen}; + $options{setOpen} = time > $set->open_date; + $options{pastDue} = time > $set->due_date; + $options{answersAvailable} = time > $set->answer_date; + $options{refreshMath2img} = $translationOptions->{refreshMath2img}; + $options{feedback_button_name} = $ce->{feedback_button_name}; # Default values for evaluating answers $options{ansEvalDefaults} = $ce->{pg}{ansEvalDefaults}; diff --git a/templates/ContentGenerator/ProblemSet/problem_list.html.ep b/templates/ContentGenerator/ProblemSet/problem_list.html.ep index 49d478934c..644200efba 100644 --- a/templates/ContentGenerator/ProblemSet/problem_list.html.ep +++ b/templates/ContentGenerator/ProblemSet/problem_list.html.ep @@ -53,6 +53,6 @@ %
