Blended learning incorporates online learning experiences and helps students for meaningful learning through flexible online information and communication technologies, reduced overcrowded classroom presence, and planned teaching and learning experience. This study has conducted surveys of various tools, techniques, frameworks, and models useful for blended learning. This article has prepared a comprehensive survey of student, teacher, and management experiences in blended learning courses during COVID-19 and pre-COVID-19 times. The survey will be useful to faculty members, students, and management to adopt new tools and mindsets for positive outcomes. This work reports on implementing and assessing blended learning at two different universities (University of Petroleum and Energy Studies, India, and Jaypee Institute of Information Technology, Noida, India). The assessments prepare the benefits and challenges of learning (by students) and teaching (by faculty) blended learning courses with different online learning tools. Additionally, student performance in the traditional and blended learning courses was compared to list the concerns about effectively shifting the face-to-face courses to a blended learning model in emergencies like COVID-19. As a result, it has been observed that blended learning is helpful for school, university, and professional training. A large set of online and e-learning platforms are developed in recent times that can be used in blended learning to improve the learner’s abilities. The use of similar tools (Blackboard, CodeTantra, and g suite) has fulfilled the requirements of the two universities, and timely conducted and completed all academic activities during pandemic times.

混合学习工具和实践：综合分析

混合式学习包含在线学习体验，并通过灵活的在线信息和通信技术、减少过度拥挤的课堂以及有计划的教学和学习体验来帮助学生进行有意义的学习。本研究调查了对混合学习有用的各种工具、技术、框架和模型。本文对 COVID-19 和 COVID-19 之前的混合学习课程中的学生、教师和管理经验进行了全面调查。该调查将有助于教职员工、学生和管理层采用新的工具和思维方式来取得积极成果。这项工作报告了在两所不同大学（石油与能源研究大学，印度和 Jaypee 信息技术学院，印度诺伊达）。评估准备学习（学生）和教学（教师）混合学习课程与不同在线学习工具的好处和挑战。此外，还比较了学生在传统和混合学习课程中的表现，列出了在 COVID-19 等紧急情况下有效地将面授课程转变为混合学习模式的担忧。因此，据观察，混合式学习有助于学校、大学和专业培训。最近开发了大量在线和电子学习平台，可用于混合学习以提高学习者的能力。使用类似的工具（Blackboard、CodeTantra、g Suite）已经满足了两所大学的要求，
