Abstract

Purpose of the study: This study aims to describe the practicum activities carried out in the Plant Physiology practicum activities of the Biology Education Tadris Laboratory, IAIN Batusangkar. Methodology: This descriptive study combines the accuracy of numerical data and a more profound understanding through observation and interviews. The population in this study were all students who took the plant physiology practicum course in the odd semester of 2019, totaling 96 people and six laboratory assistants. Data collection consisted of quantitative data collection using questionnaires and qualitative data through interviews and observations. Quantitative data analysis was carried out using the average percentage score for each activity. Furthermore, qualitative data analysis from observations and interviews was carried out by bringing up themes and information patterns from practicum activities to support quantitative data. Main Findings: Data analysis indicates that the practicum activities have been executed efficiently, evidenced by a planning score of 80.56 and an implementation score of 79.42. Additionally, the score for follow-up activity was 93.66. The overall average percentage of practicum activity execution was 84.55, indicating good category. Novelty/Originality of this study: The activities of the practicum are detailed in this article, including planning, implementation, and follow-up. In order to generate comprehensive data, the analysis employs descriptive methods that are supplemented by observational data. Research data was collected from all parties involved in the practicum activities, including students, practicum assistants, and laboratory assistants. In contrast to other researchers who exclusively employ qualitative data with samples of practicum participants.

Abstract

This study validates an analytic rubric designed to assess divergent thinking as a core dimension of pre-service biology teachers' creative thinking. The research addressed the absence of psychometrically sound assessment tools in Indonesian biology education, where creativity remains underdeveloped despite policy mandates, such as Kurikulum Merdeka, and international benchmarks, like PISA 2022. The study pursued two objectives: (1) theoretical validation of the rubric through expert judgment and inter-rater reliability, and (2) empirical validation through exploratory and confirmatory factor analyses. Eight subject-matter experts evaluated the rubric's descriptors, and 218 pre-service biology teachers completed divergent-thinking tasks based on human physiology scenarios. Content validity was calculated using Aiken's V, inter-rater agreement with Kendall's W, and construct validity and reliability through EFA and CFA. Findings indicated strong content validity (Aiken's V = 0.78–1.00) and fair to good inter-rater reliability (Kendall's W = 0.50–0.79). Factor analyses confirmed a unidimensional structure, with CFA demonstrating good model fit (RMSEA = 0.04; CFI = 0.97). All factor loadings exceeded 0.30, and composite reliability was ≥0.70 for three dimensions, though solution variety was marginally reliable. Notably, feasibility emerged as more stable than variety, suggesting that appropriateness is a stronger indicator of creativity in applied STEM contexts. The validated rubric provides theoretical insights into the structure of divergent thinking and practical tools for formative assessment in biology education. Future studies should extend validation across institutions, examine measurement invariance, and explore predictive validity to ensure broader applicability.

Abstract

Pesisir Aceh Barat memiliki mosaik habitat lahan basah seperti mangrove, muara sungai, laguna, pertambakan, dataran lumpur pasang surut, sawah pesisir, dan pantai berbatu yang berfungsi sebagai area makan, beristirahat, dan berbiak bagi burung air ordo Ciconiiformes. Bukti ekologi menunjukkan bahwa produktivitas mangrove, ketersediaan invertebrata pada dataran lumpur, serta dinamika pasang-surut menjadi faktor penting yang menentukan kehadiran dan kelimpahan kelompok burung ini. Penelitian ini bertujuan mengidentifikasi komposisi jenis dan tingkat keanekaragaman burung Ciconiiformes serta mengevaluasi kondisi habitat lahan basah di Aceh Barat. Metode yang digunakan meliputi survei lapangan melalui pengamatan langsung dengan analisis indeks keanekaragaman Shannon-Wiener dan dominansi Simpson. Hasil penelitian menunjukkan bahwa pesisir Aceh Barat memiliki potensi sebagai habitat penting, dengan famili Ardeidae sebagai kelompok paling dominan. Nilai indeks keanekaragaman Shannon-Wiener (H’ = 0,49) mengindikasikan kategori rendah akibat dominasi Bubulcus ibis. Indeks dominansi Simpson (D = 0,79) menunjukkan komunitas tidak seimbang. Temuan ini mengindikasikan perlunya pengelolaan berbasis bentang lahan melalui restorasi mangrove, perlindungan dataran lumpur, pengaturan tambak ramah-burung, dan pemantauan berbasis komunitas.
