Abstract

Tujuan dari penelitian ini adalah untuk menguji alat ukur instrumen yang digunakan untuk menilai keterampilan berpikir tingkat tinggi (HOTS) siswa dalam kimia. Jenis penelitian ini yang digunakan aadalah deskriptif kuantitatif dengan menggunakan model pengembangan tes Wilson, Oriondo, dan Antonio yang terdiri atas desain tes, uji coba tes, dan pengukuran tes diterapkan dalam penyusunan ujian kimia HOTS. Instrumen pengumpulan data berupa tes HOTS kimia berbentuk multiple choice beralasan. Temuan penelitian menunjukkan bahwa tes tersebut telah terbukti sesuai dengan PCM pada tahap uji coba dan pengukuran, menurut kriteria INFIT MNSQ. Ketiga puluh elemen tersebut sesuai dengan model, menurut batas terendah dan maksimum INFIT MNSQ, yaitu 0,77 dan 1,3. Tingkat kesulitan item berkisar dari -0,88 hingga 1,04. Tes tahap uji coba memiliki peringkat reliabilitas 0,97. Tes dengan kesalahan pengukuran terkecil, 0,21, akan menghasilkan informasi terbanyak, 20,92.

Abstract

Optimalisasi e-panduan skripsi pada mahasiswa tingkat akhir bertujuan untuk meningkatkan pemahaman mahasiswa mengenai penggunaan platform E-Panduan Skripsi sebagai alat pendukung dalam proses penyusunan skripsi. Platform ini dirancang untuk memberikan akses yang mudah dan terstruktur terhadap informasi, pedoman, serta prosedur terkait penyelesaian skripsi. Sosialisasi ini melibatkan penyampaian materi oleh narasumber yang berkompeten, simulasi penggunaan E-Panduan, serta sesi tanya jawab interaktif untuk mengatasi kendala teknis maupun substansi yang dihadapi mahasiswa. Melalui kegiatan ini, mahasiswa diharapkan dapat memahami langkah-langkah administratif dan teknis dalam menyusun skripsi secara efisien, memanfaatkan teknologi digital untuk mendukung penyusunan karya ilmiah yang berkualitas, serta meningkatkan tingkat ketaatan terhadap pedoman akademik yang berlaku. Hasil dari kegiatan ini diharapkan dapat mendukung percepatan penyelesaian studi mahasiswa tingkat akhir, mengurangi kesalahan administratif, dan menciptakan budaya akademik yang lebih terstruktur di lingkungan Program Studi Pendidikan Kimia.Penggunaan platform ini diharapkan tidak hanya mempercepat penyelesaian studi, tetapi juga membangun sistem pembimbingan akademik yang lebih terstruktur. Dengan menyediakan akses ke sumber referensi yang terstandarisasi, platform ini mendorong mahasiswa untuk menghasilkan karya ilmiatugas akhir yang lebih berkualitas.

Abstract

Science process skills (SPS) are essential competencies that students must possess during laboratory activities to support conceptual understanding and the development of scientific thinking abilities. This study aims to assess the level of students' mastery of SPS and evaluate the effectiveness of chemistry practicum activities in enhancing these skills. The research employs a quantitative approach with a descriptive-evaluative design. The subjects are second-semester students participating in a basic chemistry practicum. The SPS assessment instrument, consisting of 18 items, was developed and validated, yielding an average Aiken’s V index of 0.84, indicating high validity. The results show that most students demonstrated strong skills in observation (76%) and classification (68%), but showed weaknesses in higher-order skills such as formulating hypotheses (35%), designing experiments (30%), and understanding experimental variables (25%). Skills in data interpretation (45%) and oral scientific communication (40%) also require improvement. These findings highlight the need to strengthen inquiry-based learning and consistently apply process-oriented assessment in chemistry practicum activities to comprehensively develop students’ science process skills.

Abstract

This research aims to evaluate the quality of an instrument used to measure the chemistry proficiency of senior high school students in Yogyakarta city in response to high order thinking test questions. The evaluation employs the item response theory (IRT) approach, which considers both dichotomous and polytomous data types. The assessment involved analyzing three fundamental assumptions: unidimensionality, local independence, and invariance. The unidimensionality assumption was examined through factor analysis, revealing that the first factor contributed the most to both dichotomous and polytomous data. Local independence was tested using variance-covariance matrix analysis, which revealed that the covariance values between ability intervals were minimal or nearly zero, thereby fulfilling this assumption. Furthermore, invariance testing was conducted on both item parameters and student ability parameters. The results indicated a high correlation (0.893) for item parameters and a moderate correlation (0.761) for ability parameters, confirming that the invariance assumption was satisfied. The students’ ability levels were categorized into five levels, ranging from very low to very high. The analysis revealed that dichotomous data covered a broader range of abilities than polytomous data did. Overall, the study confirms that the instrument used is valid, reliable, and aligns with the core assumptions of IRT. These findings have significant implications for enhancing the quality of chemistry assessment tools using the IRT approach, ensuring that test questions are more accurate and dependable. These insights can help teachers design instructional methods that promote higher-order thinking skills (HOTSs), encourage the broader application of IRT in assessment, and support data-driven educational policies. Moreover, students gain improved training in analytical thinking and problem solving, leading to a deeper understanding of chemistry.
