Teacher's Tools AP Chemistry is an excellent package for the teacher of AP Chemistry. I certainly would have found a package like this a great addition to my teaching and an outstanding help for my AP Chemistry students in the past. The package contains three separate programs: the Teacher's Tools Library, Student Tutorials, and Student Monitor.

The Library is a CD-ROM of printable materials for the teacher, including worksheets, handouts, lab materials, and teacher notes. Adobe Acrobat Reader is required to print the materials and is included on the CD. A schedule of topics and the number of class periods suggested to cover the material and teacher bullet notes make preparation for the teacher very easy. The student handouts include notes and example problems, which are invaluable to the student. The worksheets have many types of questions with answers that will help students prepare for exams. The lab materials give an abstract, objectives, references, and materials needed. The procedures were not included.

The Student Tutorial is one CD-ROM that covers all topics included on the Advanced Placement Chemistry exam. The material is presented in a six-step interactive learning sequence. Step 1 is Assess Me, which is a pretest. Step 2, Teach Me, uses audio and visual presentations of the material. Step 3 is Show Me, which gives step-by-step explanations of problems. Peer tutors model the thought processes involved in solving the problems. Step 4 is Let Me Try, where the student tries interactive problems. Helps, hints, and feedback are presented as the student proceeds through the problem, allowing the student to make corrections as needed. Step 5 is Test Me, where the student works through sample test questions. The peer tutor will then give the correct solution with feedback to the student. Step 6 is Finish Me, where students are given a histogram of their progress through the five previous steps so that they know whether they have learned the material or need to review more. The teacher is able to access the students' performance through the Student Monitor portion of the package.

The topics in the Student Tutorial are presented using a floor plan as the menu. Each topic is a different floor: (1) Atoms and Electrons, (2) Molecules, (3) Gases, Stoichiometry, and Colligative Properties, (4) Kinetics, (5) Equilibrium, (6) Acids and Bases, (7) Thermochemistry and Thermodynamics, (8) Electrochemistry, (9) Chemical Reactions, and (10) Nuclear and Organic Chemistry. Each floor has three to seven stations dealing with subtopics. For example, on the first floor, there are six stations: light energy, the Bohr model, electronic structure, quantum numbers, periodic trends, and the periodic table. This allows students to quickly choose the area they want to work on. Each station takes 30 to 40 minutes to complete. Since there is usually so little class time to adequately practice problems, the Student Tutorial will allow students to have guided practice and instruction any time they are available to go to the computer.

The third component of the package is the Student Monitor. This program allows the teacher to follow the progress of each student through the student modules. This permits the teacher to see the areas that students have mastered and the areas where they are having difficulty. So many times, students cannot articulate where they may be having specific problems or they will not ask the teacher for help. The Student Monitor lets the teacher know where and what problem areas are and then can address them.

The complete Teacher's Edition includes 3 CD-ROMs--Teacher's Tools Library, Student Tutorials, and Student Monitor, plus 5 additional Student Tutorials. The cost is $599 and the software comes as either an NT network version or a stand-alone version. Individual components and extra CD-ROMs may also be purchased.
