Blended learning has been identified as a highly promising instructional approach
within vocational education institutions. The objective of this study is to examine

the disparities in speaking skills learning strategies between traditional (face-to-
face) instruction and blended learning. Additionally, the study seeks to ascertain the

impact of these learning strategies on students' speaking abilities in both traditional
and blended learning environments. The present study employs a quantitative
research approach, utilizing an experimental design. The sample for this study
comprised 120 participants, 24 participants representing Politeknik Penerbangan
Medan and 96 participants representing Politeknik Penerbangan Surabaya. The
results of this study suggest that the mere adoption of technology and the removal
of the traditional classroom setting do not suffice in establishing an optimal learning
environment for individuals learning a second or foreign language. Nevertheless,
there exists a considerable opportunity to amalgamate conventional educational
settings with contemporary technological advancements in order to enhance
students' academic achievements across various abilities and sub-skills, with a
particular emphasis on oral communication proficiency. Based on the results
obtained from the study, it is possible to draw the following conclusions: 1) A
statistically significant disparity exists in the proficiency of English speaking skills
when employing the blended learning approach. 2) A statistically significant
discrepancy is observed in the proficiency of English speaking skills for the
experimental group, thereby corroborating the efficacy of post-implementation
learning strategies.


  • The experimental group demonstrated significant improvements in various aspects of speaking skills,
    leading to a notable increase in mean speaking ability scores from pre-test to post-test, indicating an
    overall enhancement of 11.80%. Conversely, the control group showed minimal improvements,
    reflecting a minor increase in pre-test to post-test scores.

  • The ANOVA test results revealed no statistically significant difference in the mean initial ability score
    between participants exposed to blended learning techniques and those receiving traditional methods
    for the pretest. However, for the posttest, a significant difference was observed, suggesting that
    blended learning approaches significantly enhanced final ability scores compared to traditional

  • Blended learning, facilitated by multimedia sources like E-Module Aviation Speaking Preparation
    Test, creates a conducive learning environment and improves independent learning strategies,
    ultimately enhancing students' speaking achievements. Incorporating blended learning approaches in language education can lead to better learning outcomes and enhanced language proficiency, supported
    by previous research demonstrating the benefits of blended learning over face-to-face teaching.
    Providing online resources can add value to students and improve their performance, particularly in
    speaking lessons tailored to meet students' needs and interests.
