After the COVID-19 pandemic，online teaching has become an integral part of the education sector．With the advent of the post-pandemic era，the integration of education and information technology has become even closer，making online teaching an indispensable component．Both online education and traditional offline teaching have unique advantages，and the integration of these two modes into a blended teaching approach presents new opportunities for education．Therefore，it takes“New Energy Materials Preparation Experiment”as an example to explore and research the blended online and offline teaching mode for experimental courses．Addressing issues such as students’insufficient understanding and low motivation，this study uses the self-assembly of flexible self-supporting MoS 2 /CNTs composite films as an illustrative example．By fully leveraging the advantages of blended online and offline teaching，it aims to enhance the educational quality and accessibility of experimental courses，providing students with a more enriching learning experience． This research also offers novel perspectives and insights for the future educational reforms in“New Energy Materials Preparation Experiment”．

Driven by the “ability to solve complex engineering problems” of engineering education certification，the content and mode of the topic selection of electronic science integrated design course in universities are constantly reformed and innovated．Lithium-ion battery technology is the representative of the current new energy scientific and technological revolution．It has multiple characteristics of interdisciplinary and comprehensive，and meets complex engineering problems． It discusses the feasibility and effectiveness of including lithium-ion battery technology into the comprehensive design course of electronic of science，and

summarizes the specific implementation plan of comprehensive experimental design of lithium-ion battery，which lays a foundation for improving students’ability to solve complex engineering problems and training composite innovative college students．

The experimental system is built with the Michelson interferometer as the core equipment，and the debugging scheme of double light source optical interference fringes is proposed． The image processing technology based on Python is introduced to analyze the coincidence degree between the reference pattern and the adjustment pattern to judge the adjustment boundary，which realizes the accurate measurement of film thickness． Experiments were conducted using soap film as a sample，and the results showed that the experimental scheme had good operability and repeatability，improved measurement accuracy compared to visual estimation algorithms，and provided a solution for non-destructive measurement of liquid film thickness．It can also be introduced into university physics experiments to enhance students’research and innovation

abilities．

By analyzing the signiicanee and current situation of integrating the " eraftsmanship spirit” into theinnovation and entrepreneurship quality education of normal university students ( referred to as " the integrationof craftsman ’s spirit and innovation education " ), four elfeetive integration paths are explored, namelyexpanding the platform carriers of“the integration of craftsman’s spirit and innovation edueationconsolidating the teaching staff of“the integration of cratsman’s spirit and innovation educationstrengthening the value guidance of “ the integration of craftsman’s spirit and innovation education" , andcreating a good atmosphere of “ the integration of craftsman'’s spirit and innovation education".Research hasshown that only by promoting, inheriting, and practicing the spirit of craftsmanship in innovation andentrepreneurship practice can we elfectively cultivate innovation and entrepreneurship abilities , improvethequality of teacher education, raise the professional literacy of normal university students , and enhance theeffectiveness of innovation and entrepreneurship education.

With the deepening of the research of vortex light , higher requirements are put forward for thetransmission control of vortex light in various media.The on-off control of vortex optical transmissioncompleted in the three-level heat source subsystem by using the optical pump effect. The transmissior transmittance of signal light is regulated by controlling the degree of detuning of signal light ,the optical poweof pump light and the temperature of rubidium atom gas pool, so as to realize the on-off control of vortex opticatransmission.lt combines theory with experiment , so that students can fully understand theoretical knowledgthrough experiment , and cultivate and improve students' practical ability and innovation conseiousness

Wireless power transmission is a technology that can transmit electric energy between electric source and load without any physical contact．With the gradual popularization of this technology，magnetically coupled resonant radio energy transmission has come into people’s view due to its high efficiency of medium and short distance transmission．A research device is designed and made based on the principle of magnetic coupling resonance．Firstly，the relationship between energy distribution and coil distance and angle under the condition of magnetic coupling resonance is analyzed，and the image of energy distribution rule in space is obtained based on the above relationship．

The characteristic experiment of silicon solar cells is the study of the volt-ampere properties ofsilicon solar cell by means of circuit experiments.Conventional experiments do not fully take into account theelfect of the connection of the measurement apparatus on the measurement results , leading to anomalous datacurves and low elfieiency in practical operational experiments.We present three circuit connection methods forsilicon solar cell load testing and analyze the impact of different meter connection methods on the measurementresults.Students can understand the main points of photovoltaic measurement through the data processinganalysis and discussion of the experimental results. This experiment has cultivated the students ' ability toanalyze and solve problems.

To enrich the content of university experiment teaching，a new micro-angle measurement method is proposed．The method uses laser self-mixing interference technology and combines the optical characteristics of right-angle prisms，which get the features of a compact system structure and high resolution．The experiment is conducted with a He-Ne laser as the light source，and the measurement range can reach 21.49 mrad．Benefiting from strong operability and expansibility，the proposed experiment can further cultivate students’practical ability and scientific thinking．
