国家多次下发指导意见和政策支持，明确提出了提高质量是高等教育发展的核心任务，是建设高等教育强国的基本要求；要加快教育信息化进程，加强教育信息基础设施建设，推动优质教育资源的开发与应用，提高教师使用信息技术水平，鼓励学生利用信息手段主动学习。随着互联网的快速发展，教育信息化进程逐渐加快，现代信息技术与教育教学的不断融合，线上学习在实际教学中的应用越来越广泛，在关注线下学习情景中学生投入与学习效果的关系时，有必要关注线上学习情景中的学生投入与学习效果的关系。
       为了了解学生在不同学习情景中学生投入与学习效果的关系，对促进学生投入、提高学生学习效果、提升学校教育教学质量提供参考，本研究使用线下和线上学习情景中学生投入与学习效果的调查问卷，以西安电子科技大学本科生为研究对象，对不同情景中学生投入与学习效果进行调查。
       通过对国内外相关研究成果的梳理，结合相关的国家政策和学校制度，制定调查问卷，问卷分为基本信息和学习现状两部分，学习现状由学生投入和学习效果组成，其中学生投入可细分为自主学习、课程学习、师生互动、生生互动、时间管理五个维度，学习效果细分为爱国进取精神、创新思辨能力、学科知识、实践能力和国际视野五个维度。
       对研究对象发放调查问卷，并对回收的数据进行处理分析。通过描述性统计、配对T检验、相关分析和回归分析等方法，对线下和线上两种不同学习情景中，学生投入与学习效果的现状和关系分析对比。进行学生投入中各项因子对学习效果的预测，剖析出现这种情况的原因，并对提高学生学习效果提出具有针对性、可行性的策略和建议，从而促进学校培养创新型、复合型人才。本研究立足于实际情况，从学生主体的层面，关注学生投入对学习效果的影响，有利于了解学校的教育质量现状，对学校深化教育改革、提高教育质量以及加快教育信息化建设具有深远的意义。
       通过调查发现，线下和线上两种学习情景中，学生投入和学习效果的整体情况都比较好，但是师生互动投入和国际视野方面还需要加强。同时，学生投入对学习效果有正向显著影响，学生投入各项因子种对学习效果影响较大的是师生互动和课程学习，影响较小的是生生互动。并在此基础上提出对策：第一，要加强师生互动；第二，开阔学生的国际视野；第三，提高课程学习效率；第四，加强师资队伍的建设。

The country has issued guidance and policies on many occasions, clearly states that improving quality is the core task of higher education development and the basic requirement for building a strong country with higher education. It is necessary to speed up the process of education informatization, strengthen the construction of education information infrastructure, promote the development and use of high-quality educational resources, improve the level of information technology used by teachers, and encourage students to take the initiative to learn with information. With the rapid development of the Internet, the process of educational informatization is gradually accelerating, the continuous integration of modern information technology and education, online learning is more and more widely used in actual teaching. When paying attention to the relationship between student engagement and learning outcome in the offline learning scenario, it is necessary to pay attention to the situation in the online learning scenario.

In order to understand the relationship between student engagement and learning outcome in different learning scenarios, and to provide a reference for promoting student engagement, increasing student learning outcome and improving the quality of university education and teaching. This study uses offline and online learning scenarios for student engagement and learning outcome. The questionnaire surveyed the undergraduates of Xidian University as a research object to investigate student engagement and learning outcome under different scenarios.

By sorting out relevant research results at home and abroad, combining relevant national policies and school systems, a questionnaire is formulated. The questionnaire is divided into two parts: basic information and learning status. The learning status is composed of student engagement and learning outcome. Among them, student engagement can be subdivided into five dimensions: independent learning, course learning, teacher-student interaction, student-student interaction, time management. And the learning outcome can be subdivided into five dimensions: patriotism, innovative ability, subject knowledge, practical ability and international perspective.

Distribute questionnaires to the research subjects and analyze the recovered data. Through descriptive statistics, paired T test, correlation analysis and regression analysis, analyze the situation and relationship between student engagement and learning outcome in two different learning scenarios, offline and online. And predict the learning engagement of various factors in student outcome, analyze the reasons for this situation, and propose targeted and feasible ways to improve the learning outcome of students. So as to promote the cultivation of innovative and compound talents in colleges and universities. This study is based on the actual situation. From the aspect of student body, it pays attention to the influence of student engagement on learning outcome, which is helpful for understanding the status of school education quality. It is of far-reaching significance for university to deepen education reform, improve education quality and accelerate the construction of education informatization.

According to the survey, under both offline and online learning scenarios, the overall situation of student engagement and learning outcome is better, but the teacher-student interaction engagement and international perspective still need to be strengthened. At the same time, student engagement has a positive and significant effect on learning outcome. The factors that student engagement in have a greater impact on learning outcome: teacher-student interaction and course learning, and the smaller impact is student-student interaction. Based on this, countermeasures are proposed: first, to strengthen teacher-student interaction; second, to broaden students' international perspective; third, to improve the efficiency of curriculum learning; fourth, to strengthen the construction of teaching staff.
