Our student's newly created copy of the Function aplet is now totally independent of its parent aplet. The student can now (if desirable) the original Function aplet back to factory defaults and go on with the extra work that she wanted to do. A saved aplet cannot be because the calculator is no longer sure what to reset it to. To remove a saved aplet you need only press . Pressing on a normal aplet is equivalent to . Copying and adding to the Stats aplet Our second scenario had a teacher not wanting to waste the time that would be needed for his students to type in five sets of data. In this case also, the solution is to make a copy of the aplet. First set up the Statistics aplet to be exactly the way you want it... for example five data sets of 20 numbers, NUM view set to univariate stats ( ), SYMB view set up for five Box and Whisker graphs, axes set up to display all five sets. See page 114 for information on the Statistics aplet. The next stage is to move to the APLET view and this modified Statistics aplet under a new name - say "Related Sets". If desired, you can the original Statistics aplet afterwards, ready for next use. This saved aplet can now be downloaded to all the students' calculators using the infra-red link in the case of an hp 39gs or using the cable in the case of the hp 40gs. This ensures that each student has exactly the required data sets, with PLOT views pre-set to the teacher's needs. An ambitious teacher might even complete his aplet by adding a set of instructions to the Note which is associated with the aplet. This would allow an absent student to download a copy from a friend's calculator and then find instructions on what they are supposed to do in the Note. Indeed, if the students have access to the Internet and a Connectivity Kit themselves, then there is no reason that the teacher could not post the aplet on the department's web page for downloading by any students who need access due to absence from class. In both of these cases, the procedure has been to save a copy of one of the standard aplets under a different name. In neither case was there any need to do any programming and the amount of memory taken up by these copies is fairly minimal because they share most of their resources with their parent aplets. 231
