To achieve this capability requires a model of
learning chemistry more effective and emphasis on
students' thinking skills. One study design used here
is the type of techniques Hands-on Explorer
Challenge Activity. Problems in learning a learning
stimulus (Barrows, 1996).
This problem is bridging the relationship
between the content learned in the context of (real-
world situations). The students face a situation
problem solving in small groups led by tutors.
Tutors assist students in identifying the knowledge
required to solve the problem by asking questions
and monitoring the problem-solving process.
Chemistry material selected in this study, namely
benzene and its derivatives have the kind of
concepts that are abstract concrete. Besides the
problem of benzene is very close to daily life. Issues
of Benzene and its use is very close to their lives. So
students need to be introduced on a contextual
phenomenon.
One of the issues about the topic Benzene
students are introduced about synthetic pesticide
compounds as well as cases that arise in the
community, has appeared many complaints related
to the high content of toxic chemicals in food
ingredients that cause various diseases, such as
stroke, blood vessel constriction , and poisoning the
body. The farmers and people still have a strong
desire to use pesticides because of the results
obtained more quickly seen and felt immediately.
Although it must be admitted that the use of
synthetic chemicals is able to increase production,
but did not realize that the accumulation of the use
of synthetic chemicals can cause problems such as a
high content of residues in products, lead to
resistance, resurgence, and the explosion of pests
and diseases will even happen disturbance
environment life.
In this study, researchers will be introduced by
the media about the learning that will be used in the
learning Benzene Blue Flower (Clictoria ternatea).
These flowers grow in areas Kalumata, Teak and
Gambesi in Ternate. People usually use it as a
traditional treatment for the disease asthma /
shortness of breath. This interest has not been
cultivated by the people that still grows wild. Blue
flowers used as a medium of learning because this
compound contains phenolic compounds namely
Benzene derivatives. In the research project is
designed in the form of worksheets students are
required utilizing as biopesticides or blue flowers as
natural indicators.
Based on the background of the problem, the
characteristics of the concept of benzene and its
derivatives, as well as the application of concepts in
learning the researchers tried to design a study
entitled, "Learning the techniques of chemical types
Challenge Hands-on Activity Explore the Blue
Flower (Clictoria Ternatea) on the topic of benzene
and its derivatives to improve skills Conceptual
thinking high school students."
1.1 Problem Formulation
Based on the background research that has been
stated previously, the research problems can be
formulated as follows:
1. How do the characteristics of the STEM media
model with blue flowers in chemistry learning
improve students' creative thinking skills?
2. How to increase understanding of concepts and
students' creative thinking skills through the
media of Blue Flowers on the concept of
Benzene with implementation STEM model?
3. How do the teacher and students respond with
chemistry learning STEM model with Blue
Flower (Clictoria ternatea)
1.2 Research Objectives
Based on the formulation of the problem, the
objectives of the study are to:
1. Identify the characteristics of the type of STEM
model with Blue Flower (Clictoria Ternatea) on
the topic of Acid base can enhance high school
students' conceptual thinking skills.
2. Find ways of making learning media of blue
flowers (Clictoria ternatea) on the topic of Acid
and base can enhance creative thinking skills for
student SMAN 2 Kota Ternate Class XI.
3. Identify increasing student mastery of concepts
in the concept of benzene and its derivatives
through learning techniques Hands-on types
Challenge Explore Activity with Blue Flower
(Clictoria Ternatea)
1.3 Benefits of Research
The findings in this study are useful for:
a) High School Chemistry Teacher, the findings
could be used as an addition to insight,
knowledge and skills in designing, using and
developing an innovative learning chemistry, as
an operational guideline in applying learning
techniques oriented Hands-on especially on the
concept of Acid and base in learning chemistry;
For chemistry learning student learn about Acid
based and implementation topics i their life.
Implementation of the Stem Model (Science, Technology, Engineering and Mathematics) with Blue Flower (Clitoria Ternatea) to Improve
the Creative Thinking Skill of High School Students
