The Practice of Chemistry
Book Purpose and Goals

• One-semester introductory chemistry course
• For students with little or no background in
  science and math
• Written as preparation for a course in general
  chemistry or general, organic, and biochemistry.

The Practice of Chemistry
Instructional Strategy

• Introduce students to chemistry as it is
  communicated verbally, symbolically, and
  quantitatively
• Build skills in problem-solving, mathematics, and
  scientific reasoning
• Consistently apply skills in practical situations

The Practice of Chemistry
Educational Approach

• Support deep learning that is best done in a
  context where students carry out meaningful
  operations
• Part 1 provides context for operations with
  chemical examples
• Parts 2 and 3 bring out the power of these
  operations with quantitative work

The Practice of Chemistry
Teaching Flexibly Quantitative Concepts can be
Taught Early
Start with Chapter 1, then go to the nomenclature
sections of Chapters 2 and 3. Introduce the mole
concept with Chapter 4, then discuss
calculations, metric system, and molar mass
problems in in Chapter 6, 7, and 8. Go back to
Chapter 5 and then to Chapter 9 for a more
concentrated discussion of chemical reactions and
chemical stoichiometry. Present the remaining
material in Chapters 2 and 3. This order is
used by the authors!

The Practice of Chemistry
Features Chapter Practicals
The Chapter Practicals in each chapter present
particular themes related to the way chemistry is
done or used. The Practicals provide a unifying
theme for each chapter and connect chemical
concepts to a situation outside of the classroom.
Students are able to answer the questions in
the Practicals using the concepts and
problem-solving methods presented in the chapter.

The Practice of Chemistry
Features Chemistry as practiced by chemists

• The practice of chemistry uses methods that
  reflect the chemistry in the process of the
  problem solving.
• No algorithms. Ask what is the chemical system
  doing here?
• With masses and moles, use the chemical
  quantities to map the units, and then add the
  numbers.

concepts that are vital to understanding the
chapter and to solving its problems. Remember it
icons mark tables, equations and facts that
should be memorized. Make the connection icons
appear where material from earlier chapters is
referenced and used.

Making it work with mathematics
Where it all started The Practice of Chemistry
grew out of a National Science Foundation program
grant to integrate mathematics and chemistry
education. This seven-year old program, called
MATCH, continues to be taught and was the basis
of our engagement with one of the key challenges
in preparatory and general chemistry getting
students to use math well, especially algebra, in
problem solving.

Making it work with mathematics
What it means in this text The Practice of
Chemistry retains the findings of the MATCH
program through its Making it work with
mathematics sections. These special sections,
integrated throughout the text, present
mathematical concepts where they are most needed.
The terminology links to the common treatments
of algebra found in high school and intermediate
algebra textsdemonstrating to students that they
have seen this mathematics before.

Proportional reasoning
The treatment of mathematics in the Practice of
Chemistry draws on proportional reasoning in
converting from one unit to another. When two
terms are related by direct variation,
proportional reasoning implies y kx or The
k in this equation can be any valid ratio for
the y and x.

Proportional reasoning

• The book emphasizes the use of proportional
  reasoning and the conversion factor method in
• Chemical formulas and reactions (mol / mol
  ratios)
• Metric conversions (metric prefixes for ratios)
• Mass to mole conversions (molar mass)
• Mole to atom conversions (Avogadros number)
• Solution stoichiometry (molarity)
• Mass to volume conversions (density)
• Students come to see these operations as
  mathematically simple!

features that let students pull together, or
integrate, what they are doing in the course.
These include links that provide information, let
students review what they have learned, and allow
them to interactively develop their learning.

through the online Web animator. This makes use
of the downloadable program WebLabViewer
Lite. This feature is more than just an add on.
Some chapters include Web problems that require
the students to examine and manipulate animator
