Defect chemistry engineering of Ga-doped garnet electrolyte with high stability for solid-state lithium metal batteries

Ga-doped Li_(7)La_(3)Zr_(2)O_(12)(Ga-LLZO)has long been considered as a promising garnet-type electrolyte candidate for all-solid-state lithium metal batteries(ASSLBs)due to its high room temperature ionic conductivity.However,the typical synthesis of Ga-LLZO is usually accompanied by the formation of undesired LiGaO_(2) impurity phase that causes severe instability of the electrolyte in contact with molten Li metal during half/full cell assembly.In this study,we show that by simply engineering the defect chemistry of Ga-LLZO,namely,the lithium deficiency level,LiGaO_(2) impurity phase is effectively inhibited in the final synthetic product.Consequently,defect chemistry engineered Ga-LLZO exhibits excellent electrochemical stability against lithium metal,while its high room temperature ionic conductivity(~1.9×10^(-3)S·cm^(-1))is well reserved.The assembled Li/Ga-LLZO/Li symmetric cell has a superior critical current density of 0.9 mA·cm^(-2),and cycles stably for 500 hours at a current density of 0.3 mA·cm^(-2).This research facilitates the potential commercial applications of high performance Ga-LLZO solid electrolytes in ASSLBs.

A Study on the Integration of Chinese Culture in High School English Teaching

The inseparable relationship between language and culture indicates that culture teaching is indispensable in English teaching.The ultimate goal of culture teaching in English teaching is to cultivate learners’cross-cultural communication skills.Cross-cultural communication is a two-way process,which requires not only knowledge of English culture but also the use of English as a medium for disseminating Chinese culture to the outside world.However,in actual English teaching,the teaching of Chinese culture is a mere formality,and the teaching effect is not obvious.Therefore,it is necessary to conduct a survey and research on Chinese culture teaching in high school English classrooms to understand its current situation,existing problems,and their causes,so as to provide suggestions for Chinese culture teaching in high school.

A Study on the Application of Task-Driven Teaching Method in High School Mathematics Teaching: Taking “The Determination of Vertical Line and Plane” as an Example

The“Ordinary High School Mathematics Curriculum Standards(2017 Edition,2020 Revision)”clearly stated in“Teaching Suggestions”that“teaching activities based on the core literacy of mathematics should grasp the essence of mathematics,create appropriate teaching situations,put forward appropriate mathematical questions,stimulate students to think and communicate,and form and develop the core literacy of mathematics.”The task-driven teaching model is a new type of teaching method that takes tasks as the main line,teachers as the guide,and students as the main body,which can enable students to engage deeply in classroom discussions and think actively.Based on the characteristics and principles of the task-driven teaching method,this paper designs a high school mathematics classroom teaching based on the task-driven teaching method,hoping to provide a reference for the majority of front-line teachers.

Reading is the key content of high school English teaching,which can improve students’mastery of words,grammar,and other knowledge,and can expand their horizons.British and American literature is the essence of British and American culture,and its application in high school English reading teaching can help improve students’English proficiency.This paper outlines the problems of high school English teaching,analyzes the role of British and American literature in high school English reading teaching,and explores the infiltration methods of British and American literature in high school English reading teaching,in order to provide references for teachers.

Teaching Design of the Junior High School English Reading for Deep Learning

English reading holds a pivotal position in junior high school English teaching,constituting an integral component of the entire educational process.Nowadays,it is imperative for English teachers to transcend the conventional,superficial reading instruction models and adopt a deep learning framework to fashion a profound reading classroom for students.This approach allows students to engage in inductive integration,application evaluation,and internalization and transfer,enabling them to delve into seemingly intricate and challenging texts,exploring them from multiple dimensions,including content,structure,and cultural implications.Ultimately,this fosters the development of students'comprehensive reading abilities and English core literacy.This paper,drawing from the perspective of deep learning and incorporating specific case studies,aims to devise a junior high school English reading instruction design that is both academically rigorous and emotionally engaging,with a focus on enhancing students'English core literacy and overall reading proficiency.

Eating Habits of High School Students in the District of Bamako in the Context of Nutritional Transition

Introduction: Eating habits are consolidated in early childhood and continue throughout life. Adolescence is a stage of rapid growth linked to puberty affected by the nutritional transition. This study aimed to evaluate the eating habits of high school students in the district of Bamako. Methodology: The cross-sectional, descriptive study was conducted from June 15 to July 4, 2023. The sample size was calculated with the StatCalc program of the Epi 7.2 software. Data was collected using a questionnaire on KoboCollect. Analyses were performed using SPSS 26 software. Results: A total of 2400 high school students were surveyed. The average age of high school students was 16.9 years ± 1.4. The median age was 17, with extremes of 14 and 19. Of the high school students, 53.3% were boys. The sex ratio (M/F) was 1.14. About 89.4% of high school students had a Smartphone. Among high school students, 51.1% did not engage in physical activity outside of high school. Rice was the cereal most consumed by high school students (99.2%). Consumption of fish and seafood was very low (25.5%). Soft drinks were consumed on average 4.2 days/week. In addition, 60.8% of high school students consumed energy drinks. Certain eating behaviors were found in this study, such as nibbling (38.5%), eating in front of screens (79.0%), and skipping meals (46.1%). Conclusion: The most consumed cereal by high school students was rice. The consumption of ultra-processed products and sedentary leisure are habits to be monitored in the context of the prevention of food-related non-communicable diseases among high school students in the district of Bamako.

A Literature Review of Fertility Education for High School Students

Purpose: Fertility education for high school students leads them to be able to decide when to get pregnant and give birth, and to think about their desired life plan. However, knowledge of fertility in Japan is low compared to other countries. This study aims to understand the state of fertility knowledge among high school students in Japan and to clarify issues in fertility education. Method: Ten articles published from 2013 to July 2023 were selected for review from ICHUSHI Web Ver. 5 and CiNii with the keywords “high school students,” “fertility,” and “education.” The review was limited to Japanese-language literature due to differences in fertility education and knowledge between Japan and other countries. Results/Conclusion: 60% - 90% of the high school students indicated that their source of information on fertility was school lessons. Half of the students understood egg aging and the effects of smoking and drinking on fertility, but their knowledge of menstruation, male reproductive physiology/function, and infertility was insufficient. 50% - 80% of students wanted to marry by the age of 30, and 70% - 80% wanted to have children. 80% of students who attended a lecture on preconception care considered the lesson an opportunity to think about their future life plans. 90% of school nurse teachers reported that fertility should be taught in schools, and half said that egg aging, causes of infertility, and other topics should be covered in high school. Educational caution points included the consideration of developmental stages and the relatedness of the content to what had already been taught, among other things. High school is the best time for fertility education because it gives students the opportunity to accept their own sexuality and think about their future. In addition, since many students plan to marry and have children by the age of 30, the acquisition of fertility knowledge can be an effective means of future life design.

Reliability and validity of the hidden hunger assessment scale in China-revised for high school students

Objective:Hidden hunger remains a severe public health problem that affects millions of people worldwide.In China,challenges related to dietary imbalance and hidden hunger persist.Micronutrient inadequacy deserves more attention among adolescents,given its vital role in their growth and development;however,this problem appears to have been largely ignored.High school students,in particular,are often at a high risk of hidden hunger but have limited assessment tools available.Therefore,this study aims to revise the hidden hunger assessment scale for high school students(HHAS-HSS)in China and assess its reliability and validity.Methods:Based on a literature review,expert consultation,pre-experiment,and formal survey,a hidden hunger assessment scale was revised for high school students.The formal survey involved 9336 high school students in 11 of the 16 cities in Anhui Province,China,and 9038 valid questionnaires were collected and included in the analysis.The item analysis,internal consistency reliability,test-retest reliability,content validity,exploratory factor analysis,and confirmatory factor analysis of the HHAS-HSS were examined.Results:The HHAS-HSS included a total of 4 dimensions and 12 items:"vegetables and food diversity"(three items),"fruits and dairy products"(three items),"micronutrient-dense foods"(four items),and"health condition and eating habits"(two items).The results showed a Cronbach's alpha of 0.758,a split-half reliability of 0.829,and a test-retest reliability of o.793,indicating good internal consistency.Using the Bartlett's test and Kaiser-Meyer-Olkin test(KMO)to test the exploratory factor analysis presented a four-factor model of the HHAS-HSS,the KMO0 value was 0.820(P<0.001),which indicated the possibility for factor confirmatory factor analysis.Using the maximum variance rotation method,four factors were obtained,and the cumulative variance explained rate was 57.974%.Confirmatory factor analysis also supported the division of the scale into four dimensions,and the fitting indices were x^(2)=1417.656,x^(2)/df=29.534,goodness-of-fit index=0.974,adjusted goodnessof-fit index=0.958,parsimonious goodness-of-fit index=0.600,normed fit index=0.938,incremental fit index=0.940,Tucker-Lewis index=0.917,comparative fit index=0.939,and root mean square error of approximation=0.056.Except for x^(2)/df,all the indices reached the fitting standard,and the above results showed that the construct validity of the scale reached an acceptable level.Conclusions:The HHAS-HSS has good validity and reliability for Chinese high school students.It is a convenient self-report measure of hidden hunger risk.

BACKGROUND Sport help promote healthy physical and mental development of high school students.To date,there have been few studies on the effect of sport on school adaptability,resilience and cell phone addiction tendency of high school students.AIM To explore the effects of sports on school adaptability,resilience and cell phone addiction of high school students.METHODS A stratified random sampling method was used to select 600 students from two high schools in Lhasa,and Physical Activity Rating Scale,School Adjustment Scale for High School Students,Chinese Adolescents Resilience Scale,and Mobile Phone Addiction Index were used for field questionnaire survey.RESULTS Sport was positively correlated with school adaptability and resilience(P<0.01),school adaptability was positively correlated with resilience(P<0.01)and cell phone addiction was negatively correlated with sports,school adaptability and resilience(P<0.01).The direct effect of sport on cell phone addiction was significant(P<0.001),accounting for 20.51%of the total effect.The mediating effect of school adaptability on sport and cell phone addiction was significant(P<0.001),accounting for 17.38%and 35.36%of the total effect value,respectively.School adjustment and resilience had a significant chain-mediated effect on sport and cell phone addiction(P<0.001),accounting for 26.75%of the total effect.CONCLUSION Sport affected the cell phone addiction tendency of senior high school students through the mediating effect of school adaptability and resilience,and through the chain mediation effect of both.

An Empirical Study of the Effect of Inquiry Teaching on the Development of High School Students'Critical Thinking Under the New Curriculum Standards

The Ministry of Education of the People’s Republic of China has issued three guideline documents to encourage inquiry teaching to help students develop their ability to question,which is a defining feature of critical thinking.Two of the documents have clearly stated that English subject teaching should focus on building students’thinking capacity.Critical thinking is an essential feature of building thinking capacity and a key element of the core competencies the English subject seeks to cultivate.This research measures the performance of students of two high school classes in the exams conducted at the beginning,in the middle,and at the end of the experiment period during which inquiry teaching was applied to enhance students’critical thinking ability.The experiment results show that inquiry teaching can improve students’academic performance in English study and help them better develop their language skills.The implementation of the inquiry design in teaching listening,reading,and writing conforms to the law that governs the development of critical thinking,and the adoption of inquiry teaching can promote the development of critical thinking.

Discussion on the Infiltration of Experiential Career Education Concept in Biology Teaching in Senior High Schools

Based on the implementation of the new college entrance examination reform policy and the demand of related policies,the choice of subjects for high school students has shifted from the traditional relatively single model of arts and sciences division to the"3+3"model,and the topic of"how to infiltrate the concept of career education in the teaching process of senior high schools"has become increasingly important.However,at present,the implementation of career education in senior high schools is frequently limited,mainly in the form of class meetings,which instills the concept of career education to students.Therefore,the implementation effect is often not satisfactory.Therefore,experiential learning,a novel and efficient learning method,has entered public's view.Based on relevant research literature at home and abroad,we started with the importance and urgency of implementing career education in high schools,and generally reviewed the research status and future development trends of experiential career education both domestically and internationally.The practical and theoretical significance of the research were explained,and relevant concepts were summarized.Finally,strategic suggestions were proposed for integrating experiential career education concepts into biology teaching in ordinary high schools in China.

Multimodal Synergistic Strategies in High School English Teaching

This paper focuses on the multimodal synergistic strategy in high school English teaching.It first briefly reviews the relevant concepts and theories of multimodality and multimodal teaching.On this basis,it employs cases from text books published by People’s Education Press to illustrate how to exert the synergistic effect of multimodal teaching to guide English teaching practice from the perspectives of the English core qualities-listening,speaking,reading,viewing,and writing.The introduction and application of multimodal theory into English teaching practice is conducive to further promoting the“student-centered”English teaching reform,and plays a positive role in the cultivation of high school students’thinking and the improvement of core literacy.

A Survey of Digital Content Required for STD Prevention Education Taught by School Nurses

Purpose: In recent years, there has been concern in Japan about the increase in STDs among adolescents aged 15 - 19. In order to prevent STDs and guide adolescents toward desirable sexual behavior, this study’s goal was to examine the actual state of STD prevention education taught by school nurses as part of the school curriculum, as well as the kinds of digital content they wish to have for teaching on the subject. Method: An anonymous, self-administered questionnaire was distributed by email and leaflet. Targeting the 100 valid responses received from the surveyed school nurses, descriptive statistics were made for each survey item and comparisons were made between the early- and mid-career groups based on years of experience. Results: 70.0% of respondents reported teaching about STDs in Health & Physical Education classes. School nurses in the early-career group used ready-made materials, while the mid-career group used both ready-made and self-made materials. 95% of respondents reported that they had little or no knowledge of STDs, while 84% reported that they were “good” or “fairly good” at teaching classes on sexuality. Both groups reported difficulty with the topics of “phimosis” and “nocturnal emissions” in the physiological category, “sexual behavior” in the “sex-adjacent” category, and “sexual and reproductive issues” in the psychosocial category. Respondents expressed a need for digital content covering the topics of “sexual violence”, “sexual abuse”, “sexually transmitted diseases”, and “how to turn down sex”. The mid-career group desired digital content for more items than the early-career group, with significant differences in the pathogens involved in sexually transmitted diseases and sex-adjacent items. 32.0% of respondents answered that they had done self-study for sex education classes in the past three years, and both groups desired self-study on “sexually transmitted diseases”, with the mid-career group significantly higher than the early-career group on “cervical cancer & HPV”, “emergency contraceptives”, and “media literacy”. Conclusion: Health & Physical Education is the main subject that covers STDs, and pre-existing materials are commonly used. It is expected that this is due to nurses’ busy schedules and the fact that only one school nurse is assigned to each school. The data collected suggested that nurse teachers want categorized digital content that can be used in the classes they are responsible for, rather than educational content on topics they are not comfortable with. In addition, given the changing environment surrounding sex, it was clear that they wish to understand the realities and needs of the high school students they teach, and desire self-study opportunities to improve their teaching methods.
