Integrating Lesson Study and Talking Stick Model for Enhancing Student Activity and Conceptual Understanding of Inverse Functions: Implications for AI-Supported Higher Mathematics Education

This paper reports on an effort to improve student learning in a tertiary mathematics course by combining two approaches: Lesson Study (LS) and the Talking Stick (TS) model. The focus was inverse functions, a topic where students at UNIROW Tuban consistently struggled — pre-study data showed 63% low participation and 68% misconception rates around domain and codomain. We used a Collaborative Action Research (CAR) design with two plan-do-see cycles and 30 third-semester students. Data came from observation, activity questionnaires, and pre/post-tests, analyzed both quantitatively and qualitatively. Results were encouraging. Participation climbed from 63% to 86%. Conceptual understanding scores rose from 68.3 to 84.7, a statistically significant gain (t(29) = 11.45, p < 0.001, Cohen’s d = 1.35, N-Gain = 0.74). Domain/codomain errors dropped sharply, from 68% to just 12%. A strong correlation between participation and learning gains (r = 0.82) suggested the two were genuinely connected. We also discuss how the habits of reasoning developed through TS may prepare students to engage more critically with AI-assisted mathematical tools. The LS-TS combination worked here as a two-level model — improving teaching through reflection and improving learning through structured accountability. While AI tools were not directly implemented in this study, the findings highlight foundational cognitive practices — verbal reasoning, self-monitoring, and conceptual accountability — that are necessary for effective and critical engagement with AI-supported mathematical system

This study investigates the effectiveness of the Talking Stick learning model assisted by Choose Number media in improving student learning outcomes, activities, and responses in biology education on ecosystem topics. A Classroom Action Research (CAR) design was employed across three cycles at SMPN 2 Soko, Tuban, Indonesia, involving 34 seventh-grade students. Data collection instruments included student and teacher activity observation sheets, learning outcome tests, and student response questionnaires. Da ta were analyzed using descriptive statistical techniques. Results demonstrated progressive improvements across cycles. Student activity scores increased from 2.25 (Cycle I) to 2.8 (Cycle II) and 3.4 (Cycle III) on a 4 - point scale. Teacher activity scores improved from 2.1 to 2.65 and 3.2, respectively. Classical learning mastery increased significantly from 64.71% (Cycle I) to 88.23% (Cycle II) and reached 94.12% (Cycle III). Student response questionnaires indicated 89.7% positive responses. The findings suggest that the Talking Stick model with Choose Number media effectively promotes student active participation, improves teacher performance, and increases learning mastery. This research contributes empirical evidence supporting the integration of cooperative learning models with game-based media to enhance biology learning outcomes

The The Experiment on Giving Water and Sugar Solution to The Opening and Closing of Stomata as A Learning Resource for The Plant Physiology Course

This study aims to examine the effect of water and sugar solution on the mechanism of opening and closing stomata in Rhoeo discolor leaves a learning resource for Plant Physiology. The experiment was conducted through microscopic observation of the lower surface epidermis of leaves treated with pure water and 10% glucose solution alternately. The results showed that pure water treatment reduced the turgor pressure of guard cells so that stomata closed, while 10% sugar solution increased the turgor pressure which made guard cells become turgid and stomata open. These findings confirm that changes in turgor pressure due to differences in solution concentration are a major factor in the physiological mechanism of stomata opening and closing. Instructionally, this research is highly relevant as a contextual learning resource because it presents physiological processes at the cellular level in a realistic manner, making it easier for students to connect water potential theory with biological phenomena directly observable in the field

Early Childhood Teachers’ Perceptions of AI-Assisted English Language Teaching at RA YKU 02

This study investigates early childhood teachers’ perceptions of AI-assisted English language teaching at RA YKU 02, focusing on the importance of early instruction, effective strategies, and implementation challenges. Utilizing a qualitative descriptive research design, data were collected from four teachers through closed-ended Likert-scale questionnaires and in-depth interviews. The findings reveal that teachers hold positive perceptions toward AI-assisted English teaching, including the integration of digital and AI-supported media, with 4 out of 4 participants agreeing that English proficiency enhances readiness for higher education. Total Physical Response (TPR) was identified by 4 out of 4 teachers as the most suitable strategy, while 3 out of 4 teachers emphasized the effectiveness of songs, games, visual media, and AI-supported tools. However, significant hurdles were identified, as 4 out of 4 participants reported limited instructional time, inadequate media, and limited access to AI-based resources as major obstacles, alongside a fear of mispronunciation among non-specialist teachers. To address these gaps, teachers demonstrate agency by utilizing digital and AI-supported resources such as YouTube and Digital TV. This research underscores the need for continuous, context-sensitive professional development, particularly in integrating AI and digital tools, to ensure effective English instruction in religious-based early childhood settings.   Keywords: English for Young Learners, Teacher Perceptions, Raudhatul Athfal, Instructional Strategies, Challenge

Analysis of Wind Characteristics in Tuban Regency Waters, East Java: Implications for Small-Scale Fishery Operations

Wind is a critical meteorological parameter influencing sea conditions, fishing vessel safety, and the effectiveness of capture fisheries in coastal waters. This study analyzes wind characteristics in the waters of Tuban Regency, East Java, Indonesia, based on observational data from the BMKG Maritime Meteorological Station Perak Surabaya. Wind speed and direction data from October to December 2025 were analyzed using descriptive statistics and windrose diagrams to identify dominant wind patterns and their implications for small-scale fisheries. The results show that wind speeds generally ranged from 2 to 6 knots, with occasional increases to 10-12 knots, particularly from late November to early December. The dominant wind directions originated from the west (W), southwest (SW), and south (S) sectors, consistent with the seasonal monsoon transition. The average wind speed of 5 -6 knots is categorized as light to moderate, which is generally safe for small-scale fishing operations. However, speed fluctuations exceeding 10 knots require adaptive fishing strategies. This study provides baseline information for improving weather-based fisheries management and safety planning in the southern Java Sea region

Behavioral Response and Optimal Water Debit Requirement of Jatimbulan Nile Tilapia (Oreochromis niloticus) Fry at Prijetan Reservoir, Indonesia

Water debit fluctuation is a critical environmental factor in aquaculture, yet quantitative studies on optimal flow rates for Jatimbulan Nile tilapia (Oreochromis niloticus) fry remain limited. This study aimed to determine the optimal water debit for growth and survival of Jatimbulan fry and quantify behavioral responses under different debit treatments. A completely randomized design (CRD) with four debit treatments (Q1=10 L/s, Q2=15 L/s, Q3=20 L/s, Q4=25 L/s) and three replications was conducted over 60 days at the Fish Seed Center Kedungpring, Lamongan, which receives water from Prijetan Reservoir. Data were analyzed using one-way ANOVA and post-hoc Tukey HSD (α=0.05). The Q3 treatment (20 L/s) produced the highest SGR (4.21±0.15 %/day) and SR (96.3±2.1%), significantly different from Q1 and Q4 (p<0.05). Behavioral analysis showed that fry exhibited strong positive rheotaxis (85.3±4.2%) only at Q3; at Q4 (25 L/s), 68% of fish moved to stagnant zones indicating avoidance behavior. A quadratic regression model (R²=0.94) predicted the optimal debit at 19.8 L/s. This study concludes that the optimal water debit for Jatimbulan fry rearing is 20 L/s, and deviations above or below this threshold significantly reduce growth and induce maladaptive stress behaviors

Development of a Problem-Based Learning E-Module on the Human Respiratory System to Enhance Critical Thinking Skills

The 21st-century learning paradigm demands the integration of digital resources and higher-order thinking skills, particularly critical thinking. However, preliminary observations at UPT SMPN 4 Tuban revealed that eighth-grade students exhibited low critical thinking abilities, and teachers lacked digital learning resources on the human respiratory system. This study aims to develop and validate a Problem-Based Learning (PBL)-based e-module on the human respiratory system to enhance students\u27 critical thinking skills. This research employed the Research and Development (R&D) method using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation), limited to the Development stage due to time constraints. The e-module was designed using the Canva application, incorporating PBL syntax (problem orientation, student organization, investigation guidance, artifact development, and analysis/evaluation) and six critical thinking indicators. The validation instrument employed a Likert scale questionnaire assessed by three validators: two biology education lecturers and one junior high school science teacher. Data were analyzed using descriptive quantitative and qualitative techniques. The validation results demonstrated an overall average percentage of 88.37%, categorized as "valid." Specifically, the material feasibility aspect scored 88.47% (valid), the language feasibility aspect scored 89.33% (valid), and the media feasibility aspect scored 87.33% (valid). This research contributes a valid PBL-based e-module specifically designed for junior high school biology content. Further research is recommended to assess the e-module\u27s practicality and effectiveness in actual classroom settings
