Abstract

Project-Based Learning (PjBL) serves as a robust pedagogical framework to engage students in solving real-world contextual problems through empirical evidence and collaborative innovation. This study seeks to analyze the creativity of prospective chemistry teacher students in voltaic cell learning through the implementation of PjBL using local organic resources. By adopting a mixed methods design method with a repeated measures design, the study involved 10 prospective chemistry teachers enrolled in the Basic Chemistry 2 course at Universitas Cenderawasih, Jayapura, Indonesia. Research instruments included observation rating scales for creativity, pre-test and post-test assessments for conceptual mastery, and a Likert-scale perception survey to evaluate professional motivation. The results demonstrated a significant positive impact across all measured dimensions. An analysis of student creativity showed that 60% of students were "creative," 30% were "very creative," and 10% were "quite creative," especially when it came to how fluently and originally they used local plant. Furthermore, a high-category Normalized Gain (N-gain) of 0.76 validated pedagogical effectiveness, indicating a substantial increase in conceptual mastery of electrochemical principles. Technical analysis confirmed that indigenous resources, such as local lime, provided stable voltage suitable for series circuit engineering to power electronic loads. Finally, the perception survey showed a very high score (4.95/5.00) for professional intent, reflecting a strong motivation to replicate this "living laboratory" model in future careers. This ethnochemistry-based PjBL approach effectively transforms local environments into authentic scientific laboratories, fostering resourceful, innovative, and culturally responsive science educators in resource-constrained regions

Abstract

This research aims to analyze factors that support and hinder chemistry learning on atomic structure material in class XI(C). research method used is a qualitative descriptive method by describing the data obtained from test results and correlating them with IQ, aptitude, and interest tests. techniques used for data collection are observation, interviews, test questions, and documentation.Test instrument consists 42 items form multiple-choice questions that are arranged based on content validity and have been validated by experts.results obtained show that students with high IQ will also achieve high learning outcomes, namely, those with an IQ 126 achieve a learning result 95, and about 5.4% students with an IQ 117 achieve a learning result 85. Conversely, those with low intelligence will have low learning outcomes, as evidenced by 8.2% students having an IQ 62. having an IQ 62. Obtaining learning outcomes scores ranging from 54 to 58, despite some deviations, indicates that an increase in students' intelligence levels will always be accompanied by increase in learning outcomes.Talent affecting students' learning outcomes, namely scholastic talent, shows average score 17.5 learning outcomes 83, abstract thinking has average score 45 and achieves learning outcomes 83, and clerical speed accuracy has average score 42.5 with learning outcomes 83, while talents that hinder learning scholastic talent, abstract thinking,clerical speed and accuracy, as these will result in low ability scores low learning outcomes if their talent levels are low. Interest needed for learning chemistry on the topic atomic structure includes a science interest and a personal social interest.

Abstract

Penelitian ini bertujuan untuk menganalisis peran bakat sebagai faktor pendukung dan penghambat dalam pembelajaran kimia pada materi sistem periodik unsur. Penelitian menggunakan pendekatan kuantitatif deskriptif dengan melibatkan 32 siswa kelas X salah satu SMA Negeri di Jayapura. Data dikumpulkan melalui tes hasil belajar dan tes bakat yang meliputi bakat verbal, numerikal, skolastik, mekanik, abstrak, serta kecepatan dan ketelitian klerikal. Hasil penelitian menunjukkan bahwa seluruh siswa mencapai nilai di atas KKM (70), namun variasi hasil belajar tidak selalu sejalan dengan profil bakat. Bakat abstrak, skolastik, dan ketelitian klerikal menunjukkan kontribusi lebih signifikan terhadap hasil belajar dibandingkan bakat verbal, numerikal, dan mekanik. Penelitian ini menegaskan bahwa keberhasilan belajar kimia ditentukan oleh kesesuaian antara jenis bakat dan karakteristik materi pembelajaran.
