Abstract

Critical thinking is essential in economics education, yet many senior high school students are still taught through memorization-focused methods, limiting the development of higher-order thinking skills. Project-Based Learning (PjBL) offers a potential alternative by engaging students in real-world, inquiry-based tasks. This quasi-experimental study employed a nonequivalent control group pretest–posttest design involving 71 senior high school students. The experimental group received instruction using the PjBL model, while the control group followed conventional teaching. Data were collected using a validated 20-item multiple-choice critical thinking test aligned with Bloom’s revised taxonomy (C4–C6). ANCOVA was used to analyze posttest differences, with pretest scores as covariates. Hedges’ g and normalized gain (N-gain) were calculated to assess effect magnitude and improvement. ANCOVA results revealed a statistically significant difference in posttest scores favoring the PjBL group (F = 5.686, p = .020), with a medium effect size (Partial Eta Squared = .078). The experimental group outperformed the control group with a mean posttest score of 67.86 versus 60.00. Hedges’ g was 0.522, and N-gain for the PjBL group (M = 0.558) exceeded that of the control group (M = 0.435). The findings suggest that PjBL is effective in enhancing students’ critical thinking in economics, particularly when projects are grounded in real-life contexts such as local inflation data. PjBL implementation requires structured planning, authentic tasks, and clear assessment criteria.

Abstract

Minat siswa Sekolah Menengah Atas (SMA) di Kabupaten Malaka untuk melanjutkan pendidikan ke perguruan tinggi masih tergolong rendah, yang disebabkan oleh berbagai faktor seperti keterbatasan informasi, hambatan ekonomi, dan kurangnya motivasi. Kegiatan pengabdian ini bertujuan untuk meningkatkan kesadaran dan minat siswa dalam melanjutkan studi ke jenjang sarjana melalui pendekatan edukatif-partisipatif. Kegiatan dilaksanakan di SMA N 1 Malaka Barat dan melibatkan 78 siswa kelas XI. Materi yang disampaikan mencakup urgensi pendidikan tinggi, jalur masuk perguruan tinggi (SNBP, SNBT, mandiri, vokasi), jenis-jenis beasiswa, serta panduan memilih program studi dan karier. Siswa juga mengikuti tes bakat Holland RIASEC untuk membantu mengenali potensi diri dan menyusun pohon karier sebagai refleksi perencanaan masa depan. Evaluasi menunjukkan peningkatan signifikan minat siswa untuk melanjutkan studi ke perguruan tinggi setelah kegiatan berlangsung. Kegiatan ini membuktikan bahwa edukasi yang terstruktur dan partisipatif dapat menjadi strategi efektif dalam menumbuhkan motivasi siswa untuk melanjutkan pendidikan tinggi, terutama di daerah perbatasan.

Abstract

In real life, the economy is open and continuously developing, so in its learning, critical thinking skills are needed to make it easier to understand. Students need to be taught to connect the theoretical concepts taught in the classroom with real-world situations. Project-Based Learning supported by an e-module is present to overcome this issue. However, several studies have focused on science subjects or urban contexts and have not specifically addressed border (3T) regions. In this study, we examined the effectiveness of the Project-Based Learning supported by the e-module model in improving students’ critical thinking skills in high school economics learning in the context of Indonesia’s border regions. For this purpose, we used a quasi-experimental method with a non-equivalent Control Group design involving 162 eleventh-grade students from public senior high schools in Malaka Regency, at the Indonesia–Timor Leste border. The students were divided into two groups: the experimental group, which was given the Project-Based Learning supported by e-module treatment, and the control group, which used traditional textbook-based methods. To measure students’ critical thinking skills, 20 HOTS-level questions that had been tested for validity and reliability were administered. For comparison, we analyzed the covariance (ANCOVA) test by controlling the pretest variable. The results of this study showed that the Project-Based Learning supported by the e-module proved to be more effective than the traditional method. This result was also supported by questionnaire findings showing that almost all students considered the Project-Based Learning supported by e-module learning to be interesting and enjoyable.
