إستراتيجية تدريسية مقترحة قائمة على ممارسات تدريس الرياضيات الفعال للمجلس الوطني لمعلمي الرياضيات (nctm)
The study aims to design a proposed instructional strategy based on effective mathematics teaching practices. A qualitative approach was followed to achieve the study's objective. Qualitative data was used in designing the instructional strategy through the Delphi method, gathering the opinions of nineteen experts. The thematic analysis of the data revealed a set of themes distributed across the three stages of the strategy: planning, implementation, and evaluation. The planning stage included coherence, learning objectives, success criteria, prior knowledge, vocabulary, error anticipation, purpose, nature of the task, questions, multiple representations, assessment, and classroom structure. The implementation stage included lesson launch, educational activities, questioning, task execution, mathematical dialogue, and lesson closure. The evaluation stage included diagnostic assessment, formative assessment, summative assessment, and teacher self-reflection. Based on these results, the proposed instructional strategy was designed. The research concluded with several recommendations, most notably: supporting and encouraging teachers to implement the procedural steps of the instructional strategy, which represent essential practices that support the achievement of mathematical success for all students. It also recommends the development of teacher guides by experts at the curriculum development center, presenting lessons in specific steps that align with effective mathematics teaching practices.
