Locate Three Different Video Lessons That Involves Teaching Ratio Or P

Locate three different video lessons that involves teaching ratio or proportional reasoning. As a separate document, discuss whether the lesson observed: Has a clearly identifiable objective. Is aligned to the CCRs. Supports the “big ideas” stated in the text; fostering student thinking that a ratio is a distinct entity, different from the two measures that make it up; facilitating multiplicative rather than additive comparisons; and developing proportional thinking by having students compare and determine the equivalence of ratios and solve proportions through problem-based contexts rather than based on formulas. Differentiates and addresses the diverse needs of students.

Includes an informal and/or formal assessment. If so, does the assessment align to, and measure, the objective? Requires any appropriate revisions. Along with the video that you have chosen, use the Class Profile to create a lesson plan using the COE lesson plan template that incorporates the revisions. Submit a copy of the lesson plan, the link to the video, and a rationale of words that summarizes the group's evaluations of the lessons and supports the revisions. APA format, Times New Roman, 12pt., double space, in-text citations, reference(s), and Turnitin percentage less than 20%.

Paper For Above instruction

The analysis of instructional videos focusing on teaching ratio and proportional reasoning offers valuable insights into effective pedagogical practices and curriculum alignment. The selected videos exemplify different approaches to teaching ratios, emphasizing conceptual understanding, multiplicative reasoning, and real-world problem contexts. This paper evaluates each lesson against criteria such as clear objectives, alignment to the College and Career Readiness Standards (CCRS), support for big ideas of ratio as a distinct entity, fostering student thinking, differentiation, assessment alignment, and potential revisions.

Video 1: Introducing Ratios through Real-World Contexts

This lesson begins with an engaging story about mixing paint colors, where students observe and compare the ratios of primary colors to produce specific shades. The objective clearly states that students will be able to identify, compare, and create ratios in real-world contexts. The lesson aligns well with CCRS as it emphasizes multiplicative reasoning and the understanding of ratios as a distinct concept rather than just a comparison of two measures. The teacher employs visual aids and manipulatives to facilitate students’ conceptual understanding, enabling them to perceive ratios as a multiplicative relationship rather than an additive comparison. Assessment includes a task where students create their own ratio-based problem, which aligns with the learning goal.

The lesson supports big ideas by explicitly discussing how ratios differ from fractions or simple comparisons, fostering students' deep understanding of proportionality. Differentiation occurs through varied scaffolds such as group work, visual supports, and individual reinforcement activities. The assessment, both informal through observation and formal via a short quiz, effectively measures students’ grasp of ratios in practical contexts.

Potential revisions include incorporating more varied problem types, such as those requiring students to interpret ratios in different representations, to address diverse learning styles further.

Video 2: Using Proportional Relationships to Solve Real-World Problems

This lesson focuses on solving problems involving proportional relationships, such as scaling recipes or map reading. The teacher explicitly states that students will understand and apply proportional reasoning to solve authentic real-world problems. The lesson is strongly aligned with CCRS and emphasizes the importance of developing proportional reasoning as a way to foster multiplicative thinking. Visual representations, ratios tables, and graphing activities help students compare ratios and determine proportionality.

The lesson distinguishes ratios as a standalone concept by engaging students in activities that compare different ratios and determine their equivalence. The teacher emphasizes the importance of solvers understanding that proportional reasoning involves multiplicative comparison rather than addition, aligning well with big ideas in proportional reasoning. Differentiation strategies include providing supports for students with diverse needs through scaffolded problem sets and flexible grouping.

Assessment is both formative, via class discussions and student explanations, and summative, with assignments requiring students to justify their answers in writing. These assessments effectively measure students’ understanding of proportional reasoning and its application in real-world contexts.

Suggested revisions involve integrating more technology-based tools such as dynamic graphing software to deepen conceptual understanding and cater to diverse learning modalities.

Video 3: Developing Student Understanding of Ratios and Proportions through Problem-Based Learning

This lesson employs a problem-based approach where students explore ratios and proportions through realistic scenarios like comparing advertisement prices or analyzing speed and distance. The teacher’s objectives focus on students’ ability to compare, determine equivalence, and solve proportions without reliance solely on formulas. The lesson is aligned with CCRS, emphasizing conceptual understanding and the big ideas of proportional reasoning.

This lesson actively fosters the idea that ratios are distinct from mere measures by encouraging students to analyze and interpret data. It facilitates multiplicative reasoning by engaging students in tasks that require them to think about ratios and proportions in context and to develop their reasoning about equivalence through authentic problem-solving.

Differentiation is incorporated through tiered problems and opportunities for peer collaboration. The assessment includes project presentations and written explanations, which are aligned with the lesson objectives and allow for authentic measurement of understanding.

Revisions may include additional formative checkpoints during activities to provide immediate feedback and further scaffold student understanding in real-time.
