Abstract

Penelitian bertujuan menganalisis perkembangan ekonomi di Sumatera selama tahun 2014-2020 dengan menggunakan model persamaan simultan dengan data panel. Hasilnya menunjukkan adanya hubungan dua arah antara pembangunan ekonomi dan pembangunan manusia di Sumatera. Pengeluaran pemerintah dan ekspor neto berpengaruh signifikan dan positif terhadap pertumbuhan ekonomi. Konsumsi rumah tangga dan rata-rata lama sekolah berpengaruh signifikan dan positif terhadap indeks pembangunan manusia. Dua faktor penentu pertumbuhan ekonomi Sumatera adalah pengeluaran pemerintah dan ekspor neto. Konsumsi rumah tangga dan rata-rata lama sekolah berpengaruh tidak langsung terhadap pertumbuhan ekonomi.

Abstract

Students' scientific literacy and critical thinking skills are very important to meet the challenges of the 21st century, especially in science learning. This research aimed to determine the scientific literacy and critical thinking abilities of junior high school students. This research uses quantitative descriptive methods. Data collection techniques were done using instruments to test students' scientific literacy and critical thinking abilities. The research subjects were 29 class VIII students. The results of the research show that the students' scientific literacy abilities with an average score of (29.89) are very poor. Of the three indicators of scientific literacy based on PISA, evaluating and designing scientific research received a score of (41.38) poor, interpreting scientific data and evidence received a score of (20.69) very poor and explaining phenomena scientifically (27.59) very poor. Meanwhile, critical thinking skills received an average score of (37.93) which was very poor. Of the five indicators of critical thinking based on the Ennis framework, giving a simple explanation got a score of (79.31) good, building a basic classification got a score of (24.14) very poor, making an inference got a score of (31.03) very poor, making an explanation more continued to get a score of (13.79) which was very poor, managing strategies and tactics got a score of (37.93) which was very poor. The results of this research showed that the scientific literacy and critical thinking abilities of junior high school students in science learning were still low.

Abstract

Low mathematics achievement in Indonesian secondary schools persists despite ongoing curriculum reforms. This study employed a Design Thinking–guided mixed-method inquiry to analyse instructional needs and co-create a multimedia Problem-Based Learning (PBL) model that fosters critical thinking. Three purposively selected schools in Batam contributed three mathematics teachers and forty-two students. Data were gathered through two rounds of semi-structured interviews, classroom observations, and Google-Form questionnaires. Qualitative coding during the Empathise and Define stages revealed four central issues: limited transfer of concepts to problem contexts, weak foundational mastery, mismatch between learning media and student preferences, and scarce collaborative support. Only 7.2 % of students felt competent, whereas 83.3 % acknowledged frequent computational errors and 80 % were unable to apply formulas. Students preferred group discussion (67.7 %), peer tutoring (51.6 %), and audio-visual media (45.2 %). In the Ideate stage, a PBL sequence aligned with the TPACK framework was prototyped and pilot-taught in each school. Observation indicated that 67.7 % of learners participated actively in group problem-solving, while post-lesson feedback showed 74.4 % experienced clearer conceptual understanding when multimedia and peer support were combined. Teachers reported improved lesson flow and greater responsiveness to heterogeneous ability levels. The study concludes that Design Thinking, coupled with media-rich PBL, can realign pedagogy with stakeholder needs, strengthen critical-thinking dispositions, and serve as a replicable model for mathematics instruction in similar contexts. Future work should examine long-term learning gains, scalability across diverse regions, and professional development structures required to sustain technology-enhanced PBL adoption. Such evidence will clarify policy guidelines and funding priorities for equitable implementation nationwide.
