ABSTRACT
The 21st century is the age of knowledge economy, thus, to adapt the demands of
highly-quality talents, creative thinking are becoming increasingly important. In the
explosion of knowledge, education has been seen as central in fostering creative
skills of youth. An emphasis on creative problem solving in science education can
help to better preparation of students for scientific and technological problem
solving and related careers. However, the central concern of most science teachers
is a narrow focus of fostering these skills.


The involvment of creativity in education comprises that teachers must understand
the core purpose of education - trainning students ways of thinking. Teachers
should give students opportunities to connect and combine; to work with the artistic,
scientific, and historical modes of thought; to communicate in verbal, mathematical,
kinesthetic, musical, and visual languages; to understand and use frameworks as
springboards for their creativity; and to enjoy the fact that many problems with a
single answer have multiple solutions, and that many more problems have no
universally right or best answer.

Chemistry as a part of science is an essential domain of the school curriculum. The
chemistry teaching has the potential to encourage students to think flexibly, thanks
to system of theories and problems, in order to increase a variety of approaches to
solving problems and, in that way, to contribute to development of learners creative
capacities. The assumption that chemistry can stimulate creativity depends on the
way chemistry is taught.

INTRODUCTION
1.

REASON TO CHOOSE THE TOPIC

In the 21st century, the appearance of high technology society and knowledge economy
brings human a vast of challenge. To adapt and develop in new society, people must
have qualifications as well as abilities which are appropriate to this global change.

In the demand of the information society and knowledge economy, educators should
enhance the quality of education, replace the old methods by the new ones. The core
purpose of education is that education should train students ways of thinking, enhance
independent thinking ... to bring into play students’ ability and creativity.

Teaching chemistry not only enhances the personal knowledge but also applies this
learning into real life or forms a new one. Chemistry teachers are instructors who train
thinking for students, such as observation ability, problem solving ability, scientific
imagination ability … through learning, which nurtures critical and creative thinking
skills. Specially, creative teaching methods are the key point for this development.

On the other hand, chapter 1 (Atom) and chapter 2 (The periodic table and the periodic
law) consist fundamental and difficult knowledge in chemistry program which guides
students to study other parts of chemistry. Thus, it is the reason why we choose two
chapters as the main chemical contents to research the thesis: “Improving creative

thinking of high school students through chemistry teaching”

CHAPTER I: THE MAIN THEORETICAL CONCEPT

1.1

BLOOM’S TAXONOMY AND BLOOM’S REVISED TAXONOMY

As educators we are all familiar with Bloom’s Taxonomy, created in the 1950′s by
Benjamin Bloom, and the more recently revised 2001 version adapted by Lorin
Anderson.
The chart shown below compares the original Bloom’s taxonomy with the revised one:

Figure 1.1: Bloom’s Taxonomy and Bloom’s Revised Taxonomy

This new taxonomy reflects a more active form of thinking and is perhaps more
accurate. The new version of Bloom's Taxonomy, with explanations and keywords is
shown below:


Remembering – retrieving, recalling or recognizing knowledge from memory.

Remembering is when memory is used to produce definitions, facts or lists, or recite or
retrieve material.


Understanding – constructing meaning from different types of function be they

written or graphic

4


Thesis for Master Degree – University of Education 2015



Applying – carrying out or using a procedure through executing or

implementing. Applying related and refers to situations where learned material is used
through products like models, presentation, interviews and simulations.


Analyzing – breaking material or concepts into parts, determining how the parts

relate or interrelate to one another or to an overall structure or purpose. Mental actions
include differentiating, organizing and attributing as well as being able to distinguish
between components.


Evaluating – making judgments based on criteria and standards through

checking and critiquing …


Creating – putting the elements into a new pattern or structure through

generating, planning or producing. [26]

Bloom’s Taxonomy categorizes thinking skills from the concrete to the abstract knowledge, comprehension, application, analysis, synthesis, evaluation. The last three
are considered HIGHER-ORDER THINKING Skills.
Bloom’s new taxonomy positions the abilities to analyze, evaluate, and create as upperlevel skills in the cognitive domain. Therefore, critical and creative thinking are
specific types of higher-order thinking skills that contrast with the lower-order skills of
understanding and remembering. Creative and critical thinking are key elements of
university life and future career and they are extremmely necessary to problem-solve at

school and in life, so students need develop both skills gradually over time. The duty of
teachers is that they should apply Bloom’s classification as guidence to check the
progression of students’ thinking as well as nurture these higher-order thinking skills
from early school years.
But, why should students reach to higher-order thinking skills and why should teacher
reach to higher-order thinking skills in the classroom? Because higher-order thinking
skills have enormous benefits for students. The reasoning here is similar to the
5


Thesis for Master Degree – University of Education 2015
rationale for pushing knowledge into our long-term memory. First, information learned
and processed through higher-order thinking processes is remembered longer and more
clearly than information that is processed through lower-order, rote memorization. For
example, comparing the difference between memorizing a formula and explaining the
derivation of the formula, a student who has the latter-type of understanding will carry
that knowledge longer. Moreover, the student with the deeper conceptual knowledge
will be better able to access that information for use in new contexts. This may be the
most important benefit of high-order thinking. Knowledge obtained through higherorder thinking processes is more easily transferable, so that students with a deep
conceptual understanding of an idea will be much more likely to be able to apply that
knowledge to solve new problems. Ironically, teachers are in complete ignorance of the
importance of higher-order thinking skills, they are likely to ask recall questions, which
requires only remembering and understanding thinking skill, rather than require higherorder thinking skills in classroom. The reason for the focus on lower-order thinking
skills may be very simple, it is because lower-order thinking skills are easier – easier to
understand, easier to teach, easier to test, easier to learn.
The level six in Bloom’s revised Taxonomy – creating – is the highest level of thinking
as Anderson arrangement. He sees the act of “creating” as combining elements into a
pattern that had not existed before and it is the hardest skill for teachers, students to
achieve. To succeed at this level, students must be able to synthesize their thinking and
make predictions based on knowledge. If students want to achieve them, they should

begin to practice this skill from primary school. Specially, by the time students reach
high school years, the bulk of class assessment questions and discussions are great
chance to practice creative thinking skill.

Because of the importance of creativity in education and life, the following part will
mention to creative thinking skill andhow to nuture this skill for further purpose.
