Researchers and experienced educators from around the world open up the questions at the heart of teaching and learning: What kinds of learning experiences and assessment practices will best prepare students for the demands of an unpredictable, ever-shifting future? The ability to study and explore new areas without external assistance is crucial for students' future professional success.

Today's educational landscape requires a strong emphasis on developing students' independent learning skills. The heart of independent learning skills is metacognition. Metacognitive skills play a crucial role in fostering self-directed and reflective learners, especially in the context of inquiry-based learning. This study explores the effectiveness of integration of Visible Thinking Routines (VTRs) as a structured approach to enhance students’ metacognition, enabling them to engage more deeply in the learning process. VTRs, developed by Harvard’s Project Zero, provide learners with cognitive tools to make their thinking explicit, organize their thoughts, and critically reflect on their learning journey. For this reasons our research question is “To what extent are the Visible Thinking strategies effective in developing students’ metacognitive skills?”

Objectives:

• Investigate the impact of VTRs on students’ metacognitive development
• Examine how VTRs enhance students' ability to engage in reflective and independent inquiry-based learning.
• Provide practical recommendations for teachers to implement VTRs into lessons for improving students’ learning outcomes.

Furthermore, it investigates how the maturity of metacognitive skills influences knowledge quality and the cultivation of independent learning abilities. The study also examines the positive impact of reflective practices and Project Zero routines on the advancement of metacognitive skills during lessons.

In today's educational landscape, there is a growing emphasis on nurturing students' independent learning skills, which are essential for their future professional endeavors. Metacognitive skills play a pivotal role in this regard, enabling students to engage in conscious learning by identifying problems, assessing strengths and weaknesses, formulating learning strategies, evaluating solutions, and accurately assessing their knowledge and skills.

The International Baccalaureate (IB) recognized the importance of metacognitive skills and commissioned a study in August 2020 to explore their integration and support within IB programs. The study drew significant conclusions and recommendations, including the development of guidance for assessing metacognitive skills and creating a specific learning progression for metacognition, emphasizing the importance of reflective practice across all IB programs.

Inquiry-based teaching and learning (ITL) is fundamental to the success of IB programs, with teachers actively engaging students in inquiries driven by curiosity and questions. Visible Thinking routines, developed by Project Zero, are instrumental in promoting metacognitive thinking and enhancing learning outcomes. Integration of Visible Thinking routines with inquiry-based learning enhances students' metacognitive skills and engagement in the learning process.

Another critical aspect explored in this study is students' awareness of their own knowledge, as adolescents often tend to overestimate their understanding. The study introduces Tobias and Everson's Knowledge Monitoring Ability (KMA) method as a tool for assessing students' self-knowledge, enabling them to align their preliminary self-assessment with their actual knowledge levels. This method aids in the development of students' metacognitive skills, contributing to their overall metacognitive awareness and self-regulation.

In conclusion, this study provides valuable insights into enhancing metacognitive skills in mathematics education, offering practical strategies and methodologies for educators to foster students' independent learning abilities. By incorporating reflective practices, Visible Thinking routines, and assessment tools like the KMA method, educators can empower students to become more effective learners, equipped with the metacognitive skills necessary for success in their academic and professional endeavors.

Expected Outcomes: The research aims to provide evidence supporting the positive impact of Visible thinking routine strategies on metacognitive skills of students. Findings contribute to the broader understanding of effective pedagogical approaches for metacognitive development in diverse educational settings. Limitations: The study's scope is limited to a specific school and program, potentially impacting the generalizability of findings. Participants: The study involved Diploma Program students from Nazarbayev Intellectual School of Astana (11-12th grade, 17-18 years old adolescents). Stratified sampling method was implemented. The strata based on key characteristics such as grade level, mathematics class and geography class students. Research Design: The research adopted a mixed-methods approach, combining both quantitative and qualitative data collection and analysis. Pre- and post-intervention assessments were conducted to measure the impact of the implemented Visual Thinking Routines on metacognitive skills using the Metacognitive Assessment Inventory (MAI) and Tobias and Everson's Knowledge Monitoring Ability (KMA) method. Intervention: The intervention involved the integration of Project Zero strategies, particularly Visible Thinking Routines, into the mathematics curriculum. Data Collection: Quantitative Data: Pre- and post-assessment tests measured students' metacognitive skills before and after the intervention. Academic performance metrics were collected and analyzed to identify correlations with metacognitive development. Qualitative Data: Classroom observations were conducted to qualitatively assess the implementation of Project Zero strategies. Student reflections, gathered through interviews ("Student voice") and reflection surveys ("Exit ticket"), provided insights into their perceptions of the impact on their learning. Assessment Tool: Tobias and Everson's Knowledge Monitoring Ability (KMA) method was employed to assess students' self-knowledge and metacognitive awareness. Pre- and post-intervention surveys gathered subjective insights into students' perceptions of their metacognitive growth. Implementation Timeline: The intervention spanned a semester, allowing for sufficient time to observe changes in metacognitive skills. Pre-assessment occurred at the beginning, with post-assessment conducted at the end of the semester. Data Analysis: Quantitative data were analyzed using statistical tools to measure the significance of changes in metacognitive skills. Qualitative data underwent thematic analysis, identifying recurring patterns and themes in student reflections and classroom observations. Ethical Considerations: Informed consent was obtained from all participants, ensuring voluntary participation. Confidentiality was maintained, and data were anonymized during analysis.

In conclusion, the evidence gathered from the research strongly underscores the effectiveness of Visible Thinking strategies in enhancing students' metacognitive skills. Regular practice with Visible Thinking routines positively impacted student engagement, learning outcomes, and their development as thinkers. By making their thinking visible, students gained a clearer perception of task difficulty and learned to efficiently manage their time during lessons. They also exhibited improved metacognitive monitoring and became more flexible in selecting strategies Moreover, the initiatives described within the research context yielded several notable positive outcomes within the dynamics of classroom lessons: 1. Students demonstrated heightened responsibility for their learning, utilizing class time efficiently and consistently completing homework assignments. 2. Their informed choices regarding further education, particularly in the Diploma Program in Mathematics, were supported by their improved awareness of their strengths and weaknesses. 3. Students exhibited enhanced verification skills, highlighting the ability to provide multiple solution approaches and justify their reasoning in both of the subjects (Math and Geography). 4. Increased independence in learning new topics was observed, suggesting that students' metacognitive abilities facilitated engagement in self-directed learning. 5. Feedback provided by students during reflection sessions became more comprehensive, indicating active assessment of their learning progress and a desire for improvement. 6. Classroom interaction became more productive, likely due to students' heightened metacognitive skills, fostering improved communication and engagement among peers and teachers. These positive outcomes serve as compelling evidence of the efficacy of the implemented strategies in bolstering students' metacognitive skills. The findings underscore the significance of inquiry-based learning and metacognitive development in cultivating enriching learning experiences and fostering favorable educational outcomes.   Statistical results demonstrate positive correlation.
