Message: Stoichiometry Bridge Course
The ChemCollective, in collaboration with Carnegie Mellon\'s Open Learning Initiative is offering free access to an online course in stoichiometry. The course is aimed at:
- High school students who would like additional help and practice with stoichiometry concepts and problem solving
- Students about to enter AP or college chemistry who would like a review of stoichiometry
Topics covered
The course begins with foundation topics such as dimensional analysis, significant figures, the mole, and molecular weight (molar mass.) This is followed by solution, composition and reaction stoichiometry. The most advanced topics are empirical formula, limiting reagents, titrations, and using reactions to determine the composition of mixtures. You can easily customize the syllabus to offer your students any subset of these topics.
Before taking the course, students need only have a basic familiarity with the meaning of chemical formulas, such as H2O, and reactions, such as that for the burning of Hydrogen in air: 2H2 + O2 --> 2H2O.
Course features
Each topic of the course includes an introductory movie and some interactive problems with hints. These serve as interactive worked examples since reading all the hints walks you through how to do the problem. Most topics conclude with either a virtual lab, that allows students to apply their knowledge by designing and carrying out an experiment or a randomized activity that gives help and feedback as students solve a challenging problem.
A very interesting proposal for chemistry class.

Message: This resource can be useful to diversify learning methods. Indeed, it offers, according to learning topics, very interesting investigation situations. With the investigation approach the pupil becomes an actor of their training. It motivates the pupil by giving meaning to the activities. Moreover, it encourages autonomy through individual work or work in small groups.
The learning situations selected are interesting problems often rooted in real life. These problematic situations encourage the learner’s questioning and thus their interest.
However, it must be pointed out that the investigation method favoured in these tools is the experimental approach in a virtual laboratory.
And yet, with an experimental approach really experienced during lab sessions the pupils can use several skills. It is one of the assets of a chemistry lesson that raises students’ motivation and helps understanding the phenomena studied.
However, the virtual lab can have some advantages. Indeed, the student can safely carry out virtual experiments to check/try out their skills.
Moreover, if the teacher does not always have a laboratory at their disposal, this virtual laboratory can on occasions replace real life experiments.
National Reports on successful experiences to promote lifelong learning for chemistry The national reports on chemistry successful experiences to promote lifelong learning for chemistry are now available on the related section of the project portal. The reports presents examples of successful experiences in the partner countries and the results of testing of ICT resources with science teachers.
