Abstract

This study investigated the effect of Design Thinking-Based Learning (DTBL) on students’ learning independence and creative thinking skills based on adversity quotient (AQ). A quasi-experimental pretest–posttest control group design was employed involving 69 tenth-grade students of SMA Negeri 1 Sidrap. The experimental group was taught using DTBL, while the control group received Project-Based Learning (PjBL). Learning independence was measured using a self-regulated learning questionnaire, creative thinking skills were assessed using a Torrance-based creative thinking test, and AQ was measured using an adaptation of Stoltz’s Adversity Response Profile (ARP). Data were analyzed using descriptive statistics and factorial Analysis of Covariance (ANCOVA). The results showed that DTBL significantly affected learning independence (F = 4.602, p = 0.036) and creative thinking skills (F = 5.052, p = 0.028). The mean posttest score of learning independence in the DTBL class (M = 109.23) was higher than that of the PjBL class (M = 103.00), while the mean creative thinking score in the DTBL class (M = 61.74) also exceeded that of the PjBL class (M = 59.85). AQ significantly influenced learning independence (F = 9.222, p = 0.003), but not creative thinking skills (p = 0.279). A significant interaction between learning model and AQ was found on learning independence (p = 0.020), whereas no interaction effect was observed on creative thinking skills (p = 0.813). Therefore, DTBL was more effective than PjBL in improving students’ learning independence and creative thinking skills.

Abstract

This study aims to analyze the relationship between metacognitive awareness, self-efficacy, and learning motivation on biology learning outcomes of eleventh-grade students in public high schools in Soppeng Regency, both directly and indirectly. This quantitative study employed an ex post facto correlation approach with Structural Equation Modeling (SEM) analysis techniques. A sample of 505 students was selected using simple random sampling and proportional sampling techniques from a total population of 1.444 students. The instruments used included questionnaires on metacognitive awareness, self-efficacy, and learning motivation, as well as a biology learning achievement test. The results showed that metacognitive awareness was significantly related to learning motivation (p=0.00), but had no direct effect on learning outcomes (p=0.06). Self-efficacy was significantly related to learning outcomes (p=0.01), but not significantly to learning motivation (p=0.06). Learning motivation was also significantly related to learning outcomes (p=0.00). Indirectly, metacognitive awareness has a significant relationship with learning outcomes through the mediation of learning motivation (p=0.00) and self-efficacy (p=0.02). However, the indirect relationship between self-efficacy and learning outcomes through learning motivation was not significant (p=0.16). The conclusion of this study confirms that learning motivation plays a crucial role as a primary mediator. Increasing metacognitive awareness and self-efficacy needs to be optimized in an integrated manner to improve student learning outcomes.

Abstract

The emergence of antimicrobial-resistant pathogens reinforces the critical need for new antibiotics sourced from unexplored microbial habitats. Actinomycetes remain the most prolific bacterial producers of bioactive secondary metabolites, yet tropical karst ecosystems and plant-associated rhizospheres in Indonesia remain poorly investigated despite their ecological complexity. This study aimed to isolate, screen, and characterize Actinomycetes from the karst and rhizospheric environments of South Sulawesi, Indonesia, and to identify isolates capable of producing antibacterial compounds. A total of 42 isolates were obtained using heat-shock pretreatment and selective Starch Casein Agar. Preliminary antagonistic assays against Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 35218 identified four active isolates. Two isolates KMR 1E2 and SDR 2a exhibited strong inhibition (>30 mm) against S. aureus, while SDR 9.9 inhibited E. coli. Morphological and phenotypic characterization revealed diverse spore-chain architectures, colony color profiles, carbon and nitrogen utilization patterns, salinity tolerance, melanin production, and variable growth under different pH and temperature conditions. Ethyl acetate extracts of KMR 1E2 and SDR 2a demonstrated potent antibacterial activity, and TLC-bioautography identified three active metabolites (Rf 0.73, 0.48, 0.34), with the Rf 0.34 spot associated with an alkaloid-type compound. The minimum inhibitory concentration (MIC) of KMR 1E2 extract against S. aureus was 0.3125 mg/mL. This study confirms that tropical karst ecosystems in Indonesia are promising reservoirs of antibiotic-producing Actinomycetes and provides a foundation for future genomic and chemical elucidation studies

Abstract

Despite the growing emphasis on student-centered learning in science education, many biology classrooms continue to rely on teacher-centered instruction, resulting in limited development of students’ science process skills and learning outcomes. This study aimed to investigate the effect of the Deep Learning approach on science process skills and biology learning outcomes among Grade XI students at SMA Negeri 1 Adonara Barat. A quasi-experimental study employing a nonequivalent control group design was conducted with 70 students selected through purposive sampling. Thirty-five students were assigned to the experimental group and 35 students to the control group. Data were collected using a science process skills essay test and a biology achievement multiple-choice test and were analyzed using descriptive and inferential statistics. The results showed that students taught through the Deep Learning approach achieved higher science process skills than those receiving conventional instruction, as reflected by a high N-gain score (0.70), 89% classical mastery, and a significant difference between groups (p = 0.001). The experimental group also demonstrated superior biology learning outcomes with an N-gain score of 0.65, 83% classical mastery, and a significant difference compared with the control group (p = 0.000). These findings suggest that meaningful, mindful, and joyful learning experiences enhance scientific inquiry skills and conceptual understanding. Furthermore, improvements in science process skills were accompanied by better academic achievement, indicating a close relationship between scientific practices and learning outcomes. Therefore, the Deep Learning approach is an effective pedagogical strategy for improving both science process skills and biology learning outcomes in secondary education.

Abstract

Purpose: This study was conducted to design a Biology module grounded in local Socio Scientific Issues (SSI) and integrated with (RQA) approach for environmental change topics. It also aimed to evaluate the module’s validity, practicality, and effectiveness in facilitating Biology learning at the senior high school level. Methods: This research employed a Research and Development (R&D) design adapted from the Borg and Gall development model. The study was conducted at UPT SMA Negeri 2 Sinjai with 59 tenth-grade students and two Biology teachers. Data collection was carried out using expert validation instruments, practicality questionnaires completed by teachers and students, and learning achievement tests administered through pretest and posttest. The collected data were then analyzed using Gregory’s content validity coefficient to determine validity, percentage analysis to assess practicality, and N-Gain analysis to measure the increase in students’ learning outcomes. Findings: The developed module achieved a Content Validity coefficient of 1.00, which reflects a very high level of validity. This result was supported by the strong ratings given by both validators across all 35 assessed indicators. In terms of practicality, the module received an average score of 94% from teachers and 89% from students, placing both results in the highly practical category. Furthermore, the effectiveness evaluation produced an average N-Gain score of 0.77, which falls within the high category, with 73% of students demonstrating a high level of learning improvement. Research Implications: The module can be used as an alternative contextual teaching material that supports active learning and improves students’ understanding of environmental change. Originality: This study offers a locally contextualized Biology module that uniquely integrates SSI with the RQA approach to connect biological concepts with real environmental issues.
