Active methodologies for teaching propose tools and strategies for improving student learning by using participative and integrative approaches. These lead students to autonomous research for industry problems and solutions. This study aimed to apply active-project active methodologies to undergraduate soil microbiology and inoculant courses to verify students’ perception of their knowledge levels on these topics. Forty undergraduate students received the traditional methodology that presented theoretical contents referring to the soil microbiology and inoculants; one group of twenty also elected to receive active methodologies based instruction during which they developed active projects that were structured in seven steps: briefing, bibliographic research, problematization and resolution, solutions, abstract and banner creation, and presentation. At the end of the academic year, all students answered a questionnaire to verify the perception of their levels of knowledge of soil microbiology and inoculants. Regarding the topic of microbial inoculants, perceived knowledge was the same for both groups, but overall, the active methodologies group had higher perceived knowledge of good practices of inoculation. The two groups were clustered by a multivariate approach, confirming that the use of active projects can increase the knowledge and level of subject matter understanding. The active projects contributed to undergraduate students’ increased assimilation and perceived understanding of soil microbiology subject matter content and microbial inoculant issues. The active projects can be explored in other subdivisions of soil science, including agriculture and environmental studies.

积极的土壤微生物学教学和接种剂应用项目，以提高对主题的理解和知识的获取

积极的教学方法提出了通过使用参与性和综合性方法来改善学生学习的工具和策略。这些引导学生自主研究行业问题和解决方案。本研究旨在将主动项目主动方法应用于本科土壤微生物学和接种剂课程，以验证学生对这些主题的知识水平的看法。40名本科生接受传统方法论，介绍土壤微生物学和接种剂的理论内容；一组 20 人还选择接受基于主动方法论的指导，在此期间他们开发了分为七个步骤的主动项目：简报、书目研究、问题化和解决、解决方案、摘要和横幅创建以及演示。在学年结束时，所有学生都回答了一份问卷，以验证他们对土壤微生物学和接种剂知识水平的看法。关于微生物接种剂的主题，两组的感知知识相同，但总体而言，主动方法组对良好接种实践的感知知识更高。两组通过多元方法进行聚类，证实使用活跃项目可以增加知识和主题理解水平。积极的项目有助于本科生增加对土壤微生物学主题内容和微生物接种剂问题的同化和感知理解。活跃的项目可以在土壤科学的其他细分领域进行探索，包括农业和环境研究。
