In order to assist current KembloX users, future KembloX
users, and potential KembloX users, a new page has been created on the https://Kemblox.org site. The page is entitled
“CLASS ACTIVITIES” and it will comprise models of activities related to the use
of the KembloX™ system in the classroom and/or in the laboratory. The models
can be tailored by educators according to their needs and preferences.
For starters, a first class activity was published, to be
followed by other class activities. This first class activity is simply
entitled “Ionic Compounds Modeling with
the KembloX™ System” and can be used in connection with the following
-Definition of Anions and Cations
– Naming ions, both monatomic and polyatomic
-Formula Unit (aka Empirical Formula)
-Naming of ionic compounds, including Stock notation.
We hope that you will include this class activity into your
syllabi, as KembloX™ proved to be an effective educational tool.
As always, KembloX appreciates feedback, ideas, and
suggestions for improvement.
Our poster at the 2019 IUPAC Congress enjoyed a vivid interest, i.e. people that saw it remembered it when they saw the display :)), and realized the KembloX’s potential to facilitate the learning and the teaching of the ionic compounds’ chemistry.
This year is the 100th anniversary of IUPAC and the 150th anniversary of the Periodic Table of the Elements. KembloX™, a tool for Chemical Education, honors all IUPAC conventions and it innovates in the field of the Periodic Table. KembloX will be present as both exhibitor and technical contributor to the IUPAC Congress in Paris (https://www.iupac2019.org/).
The KembloX™ booth is situated in the center of the floor,
on the second level of the Palais de Congres, Porte Maillot. We’ll be very
happy to see you there.
The technical presentation, entitled “The KembloX Effect on Students’ Learning” is part of Theme 5 – Chemistry Education, in the section on Tools in Chemistry Education. It presents preliminary research showing significant improvement in students’ performance with respect to learning; copies are available upon request.
The KembloX™ educational system (https://kemblox.org) is used to illustrate
chemical terms and concepts such as: ionic charge and formation of ionic
compounds, Stock notation, nomenclature of ionic compounds, dissociation in
solution, metathesis reactions with precipitate formation, full ionic equation,
net ionic equation, spectator ions, limiting reactant, and excess reactant. From
a didactic perspective, KembloX™ addresses two of the main learning styles: visual and kinesthetic (tactile), by
using complementary blocks and color coded interrelated objects. The
system comprises three parts: a set of color-coded, complementary blocks that
can be assembled according to chemical principles, a chart of most common
monatomic and polyatomic ions, and a four-sided spinning top used for
educational purposes; the same color code is used for all items.
In this communication we present preliminary results on the
“KembloX effect”. We calculated the
grade improvement for a quiz related to the ionic compounds’ formula unit.
Based on a paired t-test, the results indicate that, with 95% confidence, the
improvement in grades is in the interval 6 – 15 points (on a 0-100 scale).
KembloX™ is a system designed to enhance the experience of learning the chemistry of ionic compounds.
With KembloX™, learning transforms from “work” into “play”, giving educators and students a hands-on tool to help promote the learning and understanding of important chemical concepts regarding ionic compounds, both inside and outside the classroom.
