realization of the material, considered the most suitable
for being sufficiently prescriptive, clearly establishing the
phases and sub-phases of production.
• In addition, to create attractive multimedia didactic
materials, with interactive activities, videos, audios,
photographs, animations, etc., which were incorporated into
the MEHI, the use of an author tool was required. Investigating
the advantages, disadvantages and potential of these tools,
it was decided to use Educaplay because it has advantages
both in technical aspects such as installation, usability,
compatibility, license, etc., as well as in psychopedagogical
aspects such as the ability to produce attractive, motivating,
relevant materials, effective and with impact.
Contributions to the context of use and evaluation of
the material
Once the MEHI was produced, the possibility of carrying out
a real educational application experience to evaluate the
impact of the material was assessed.
A case study was proposed in the context of a cross-sectional
descriptive research. For this, the MEHI hypermedial
material was incorporated into a Flipped Classroom or
flipped classroom modality, where the student receives the
hypermedial material prior to the class, uses it to understand
the contents and then in class, activities are carried out in
which They involve more complex cognitive processes, in
order to consolidate, with the teacher’s assistance, the prior
learning carried out by the student.
The case study was developed at UNNOBA, in the General
and Inorganic Chemistry subject that is dictated for the
Engineering and Genetics careers.
To evaluate this classroom experience, qualitative and
quantitative techniques were articulated that made it
possible to account for the scope and limitations of the
implemented didactic strategy.
The evaluation tools used were: evaluation of the MEHI
production phases, student survey, teacher survey, participant
observation, analysis of student productions and data
triangulation. Control groups were used to compare the results.
Hypermedial educational material with contents in
Electrochemistry
The main contribution of this thesis was the Interactive
Hypermedial Educational Material (MEHI), in which the
Electrochemistry topic is addressed in four chapters, which
include contextualization of the topic and its technological
applications, development of previous content, Galvanic
and Electrolytic cell addressed in four sections: Before
starting, Contents, Exercises, Self-evaluation, Evaluation
with return to the tutor and To know more. It includes 46
interactive activities: 11 activities to complete text, 6 to
video quizzes, 5 to relate columns, 10 to interactive maps,
7 tests and 6 presentations.
Future Research Lines
Continuous updating of the theoretical framework of the
teaching and learning of Chemistry with the incorporation
of digital materials.
• Incorporation of experimental activities through virtual
Chemistry laboratories.
• Production of materials that promote self-management
learning in asynchronous proposals or group learning in
collaborative contexts.
• Designs of blended and distance courses for the teaching
of Chemistry, including experimental practice, that require
minimal connectivity and can be used on mobile devices.
• Development of virtual formative evaluation systems.
