What is the best way for teachers to demonstrate the effectiveness of a new instructional method after a workshop?

Assembling portfolios that reflect student work and discussing the results with other teachers is the most effective way for teachers to demonstrate the effectiveness of a new instructional method after a workshop. This approach not only showcases actual student outcomes but also provides tangible evidence of learning and engagement that has occurred as a direct result of the new methods.

Portfolios allow for a comprehensive collection of student work over time, which can highlight progress and development across various skills and subject areas. By including a variety of student projects and assessments, teachers can illustrate how the instructional method has impacted different learners. Moreover, when they engage in discussions with fellow educators, it fosters collaborative reflection and professional growth, as teachers can share insights and best practices. This peer engagement enhances the validity of the findings by incorporating multiple perspectives on the instructional approach's effectiveness.

In contrast, while creating a formal report for administration or publishing results in a teaching journal are useful for documentation and sharing insights, they may not provide immediate, actionable feedback that can be explored in real-time with student work. Conducting a survey of student attitudes offers valuable information, but it primarily captures perceptions rather than direct evidence of learning and achievement. Therefore, the portfolio method stands out as a holistic way to illustrate the impact of instructional changes.
