3. Chemistry is involved with various and diverse
interactions of matter either around us or simply
inside the laboratory. These are described using the
language of chemistry which consists of symbols,
formulas and equations (owlcation.com, n.d.).

4. CHEMICAL NOMENCLATURE
Nomenclature is the process of naming chemical
compounds with different names so that they can be
easily identified as separate chemicals.
• The primary function of chemical nomenclature is
to ensure that a spoken or written chemical name
leaves no ambiguity concerning to what chemical
compound the name refers. Each chemical name
should refer to a single substance.

5. It is important to be able to recognize and name all
chemicals in a standardized way. The most widely
accepted format for nomenclature has been
established by IUPAC. (LumenLearning, n.d.)
The International Union of Pure and Applied
Chemistry (IUPAC)

6. Naming Ionic Compounds
Ionic compounds have a very basic naming system.
The first part of the name is simply the name of the
metal element, while the second part of the name
changes the ending of the nonmetal compound to
ide (Academy and Academy, 2019).
Example: FeCl2=Iron Chloride

7. Naming Covalent Compounds
For covalent compounds or chemical compounds
with more than one formula, we use Greek prefixes
to indicate how many atoms of each molecule are
present. Common Greek numeral prefixes are as
follows: mono, di, tri, tetra, penta… (Academy and
Academy, 2019).
Example: N2S3
Dinitrogen trisulfide

1. Identify the problem in teaching practice and the learning
goals for students.
• difficulty in applying the learned concepts, or in understanding
the main concepts in naming and writing formula of chemical
compounds.
2. Worksheet solution by cooperative group. (Group Activity)
• Worksheet is prepared using various binary compounds. The
students of the study group are divided into groups; each group
consists maximum of three students and minimum of two. Each
group is asked to discuss and write the name and formula of the
organic compound in the blank. The present remedial strategy
fosters the importance of sharing the learning among them. It
fosters team building. Together everyone achieve more (TEAM).

3. Extended Learning Activity/Alternative Learning
(Individual Activity)
• Each student is asked to write the list of household
products containing inorganic compounds (name and
formula). This activity helps the students to achieve
the intended learning outcomes and enhance
conceptual understanding, deep learning and
correlate the subject with day today life. It helps/
fosters the students to master the concept and
interest.

4. Use Friendly Presentation
• Presentation is the heart of the teaching process. The
best way of getting students excited in chemistry is by
presenting it in a dynamic manner. Instructors may
buttress the lectures with the combination of boards
and audio-visual aids such as overhead
transparencies, PowerPoint slides and videos, etc [5]
that makes chemistry more alive and real to the
students as our millennium students are mostly visual
learners due to the image-centric, visual world in
which they are raised.

4. Use Friendly Presentation
Illustrate with analogies
• Even the most abstract concepts in chemistry can be
illustrated by examples or by analogies. It is beneficial
to include as many analogues as possible to illustrate
basic concepts in the lectures. It takes time to prepare
but it is extremely rewarding. In this way, students are
able to correlate sophisticated concepts in chemistry
with easy to comprehended analogies.

Correlate with everyday life
• Chemistry touches all aspects of our lives. An
experienced instructor is able to connect the
depth of the science of chemistry with its every-
day-life importance.

Problem Solving
• Students must learn to explore problems and
understand that taking a “wrong” step is often just
as valuable as following the correct path. Students
should be observant and self-critical during the
problem-solving process to evaluate whether they
are getting closer to or farther from the desired
solution.

15. Teaching Strategies in teaching Nomenclature and

Modeling
• By developing and modifying models, students can
refine their understanding, and eventually develop a
consensus model. Deliberately teaching that all
models have limitations allows new types of models to
be introduced to further explore the depth of the
concepts and recognize limitations in facets of
understanding. Then, to help students understand
these abstract concepts, carefully prepared analogies
and models can be used.

16. Teaching Strategies in teaching Nomenclature and

Choice
• Many students can demonstrate achievement of
course goals when they have the option to choose
how to express their understanding through
alternative modes such as by delivering an oral
presentation, creating a portfolio, or completing a
creative project.

17. Chemistry is an incredibly fascinating field of study.
Because it is so fundamental to our world, chemistry
plays a role in everyone's lives and touches almost
every aspect of our existence in some way. Chemistry
is essential for meeting our basic needs of food,
clothing, shelter, health, energy, and clean air, water,
and soil. Chemical technologies enrich our quality of
life in numerous ways by providing new solutions to
problems in health, materials, and energy usage.
Thus, studying chemistry is useful in preparing us for
the real world.

18. Chemistry is often referred to as the central science
because it joins together physics and mathematics,
biology and medicine, and the earth and
environmental sciences. Knowledge of the nature of
chemicals and chemical processes therefore provides
insights into a variety of physical and biological
phenomena. Knowing something about chemistry is
worthwhile because it provides an excellent basis for
understanding the physical universe we live in. For
better or for worse, everything is chemical (Why
Study Chemistry - Chemistry and Biochemistry, n.d.).

19. In general, inadequate conceptual understanding is
one of the common obstacles that students taking
chemistry face. This situation is exacerbated by the
lack of incentives and interest. However, an
experienced instructor can make chemistry vivid and
understandable to attract the interests, which in turn
leads to learning enhancement.
