3. BACKGROUNDSTEM (Science, Technology,
Engineering, Mathematics)
integration promotes active,
contextual, and project-
based learning.
Limited availability of modules
specifically designed to foster
these skills.
Problem-solving skill is
essential in 21st-century
learning.
Need for innovative digital
teaching modules aligned
with the Merdeka
Curriculum.

4. RESEARCH PURPOSE
Develop a STEM-based digital module
on “Energy and Its Changes.”
Evaluate its:
1.Validity (expert assessment)
2.Practicality (ease of use and
implementation)
3.Effectiveness (learning improvement &
problem-solving skills).
4.Provide a foundation for improving
STEM-based learning in vocational
schools.

5. RESEARCH METHOD
Research Design:
Research & Development
(R&D) with ADDIE model
(Analyze–Design–Develop).
Instruments:
Validation sheets,
observation sheets,
pretest–posttest,
student worksheets.
Data Analysis:
Mean score, N-Gain,
and reliability (%
agreement).
Participants:
Grade X students,
SMK Penerbangan
Banjarbaru.

6. PjBL Syntax
STEM Activity (Mini Solar
Panel Project)
Problem-Solving Skill
Formulate driving question
Design how to make a mini
solar panel
Clarify problem
Design plan
Create design & select
materials
Brainstorm ideas
Schedule production Plan workflow
Evaluate & select best
option
Monitor project Build and test connections Implement solution
Test results Measure voltage/current Assess effectiveness

TEST VALIDITY
Format, language, and content = Very Good
Reliability = 80% (Good)
Revisions: clearer objectives, improved color
design, added answer key.
Validity per item ≈ 3.5 (Very Good)
Revisions: added problem-based items and
scoring rubric.

10. PRACTICALITY RESULTS
Observations over 4 meetings: all aspects rated Very Good
(avg. = 3.38).
High reliability between observers.
Module considered easy to use, engaging, and time-efficient
for teachers and students.

EFFECTIVENESS RESULTS
STEM–PjBL enhances critical thinking, creativity, and collaboration.
Students engage in contextual problem-solving and project creation.

12. STEM-based digital module: Highly valid, highly practical, moderately effective.
Students’ problem-solving skills improved but remain not optimal.
Needs refinement through:
➡️ Full Implementation & Evaluation stages of ADDIE.
➡️ Larger-scale trials and extended classroom application.
➡️ Potential to strengthen 21st-century skills and STEM literacy in vocational education.
