Technology and millennials have created a shift in the world and how it operates. This impact has been experienced in the field of occupational therapy education. As a result of this paradigm shift, an analysis of effective teaching methodologies was carried out to assess the most effective way to engage the millennials in an analysis of occupation process, which is a critical foundation for effective critical thinking and clinical practice for occupational therapists. An action learning assignment was utilized to bridge this gap. The action learning assignment immersed the students in a safe learning environment that recreated many types of domains that needed to be analyzed. As a result, the students experienced first-hand the outcomes of effective and ineffective analysis and problem-solving during their action learning project. Therefore, the students were able to reflect and critically think through alternatives and hear about other students' projects. Overall, the action learning project yielded positive learning and engaging outcomes. 相似文献

利用12种植物材料,应用分光光度法对分别以丙酮和乙醇作为提取剂,并同时各采用研磨与浸泡两种方法的叶绿素含量测定值进行比较研究.结果显示,4种方法测定的植物叶片叶绿素含量均具有一定的相关性,其中,乙醇浸泡法与乙醇研磨法的相关程度最高.且用乙醇作为提取剂测定植物叶片叶绿素含量比较稳定,尤其用乙醇浸泡法测定的人为误差相对较小. 相似文献
