Strategies to Improve the Effectiveness of Classroom Teaching for Philosophy Teachers

The purpose of this study is to achieve two objectives.First,to compare the effectiveness of philosophy classes in two administrative classes of Liupanshui Normal University,and to explore the influence of the strategies used by the teachers in the two administrative classes in philosophy teaching on the students.Secondly,through the comparison and discussion of the first point,this paper puts forward the implementation strategies to improve the effectiveness of philosophy classroom,so that students can accept and absorb these knowledge points to the maximum extent to improve the teaching effect.Liupanshui Normal University is located in a remote mountain area of China,so students don't have enough knowledge and guidance in philosophy.Therefore,it is necessary to improve students'philosophical quality through effective classroom practice,so that they can better adapt to the society.Taking case study as the research method,this paper conducted observation,questionnaire survey,interview and literature analysis on philosophy teachers,students,parents,employers and school administrators.The results show that the effect of traditional teaching methods is not as good as audio-visual teaching tools,and the application of audio-visual materials in philosophy teaching has successfully endowed students with higher intellectual value and stimulated their creativity and innovative spirit.In addition,continuous improvement in teachers'emphasis on evaluation feedback,interaction and knowledge literature learning has a positive impact on students,as these strategies encourage them to use higher-level thinking skills.

Statistical Study of foF2 Diurnal Variation at Dakar Station from 1971 to 1996:Effect of Geomagnetic Classes of Activity on Seasonal Variation at Solar Minimum and Maximum

The statistical study of F2 layer critical frequency at Dakar station from 1971 to 1996 is carried out. This paper shows foF2 statistical diurnal for all geomagnetic activities and all seasons and that during solar maximum and minimum phases. It emerges that foF2 diurnal variation graphs at Dakar station exhibits the different types of foF2 profiles in African EIA regions. The type of profile depends on solar activity, season and solar phase. During solar minimum and under quiet time condition, data show?the signature of a strength electrojet that is coupled with intense counter electrojet in the afternoon. Under disturbed conditions,?mean intense electrojet is observed in winter?during fluctuating and recurrent activities. Intense counter electrojet is seen under fluctuating and shock activities in all seasons coupled with strength electrojet in autumn. In summer?and spring under all geomagnetic activity condition, there is intense counter electrojet. During solar maximum, in summer and spring there is no electrojet under geomagnetic activity conditions.?Winter shows a mean intense electrojet. Winter and autumn are marked by the signature of the reversal electric field.

Analysis of the third harmonic for class-F power amplifiers with an Ⅰ–Ⅴ knee effect

The appearance of third-generation semiconductors represented by gallium nitride （GaN） material greatly improves the output power of a power amplifier （PA）, but the efficiency of the PA needs to be further improved. The Class-F PA reduces the overlap of drain voltage and current by tuning harmonic impedance so that high efficiency is achieved. This paper begins with the principle of class-F PA, regards the third harmonic voltage as an independent variable, analyzes the influence of the third harmonic on fundamental, and points out how drain efficiency and output power vary with the third harmonic voltage with an I-V knee effect. Finally, the best third harmonic impedance is found mathematically. We compare our results with the Loadpull technique in advanced design system environment and conclude that an optimized third harmonic impedance is open in an ideal case, while it is not at an open point with the I-V knee effect, and the drain efficiency with optimized third harmonic impedance is 4% higher than that with the third harmonic open.

体育锻炼参与对老年人阶层认同的影响——基于CGSS(2010—2021)混合截面数据的分析

该研究基于2010—2021年7次中国综合社会调查(CGSS)中60~85岁老年人的混合截面数据,运用Ologit回归、工具变量法、KHB模型和交互项调节效应检验等方法对体育锻炼参与影响老年人阶层认同的机制及变化进行了研究。研究得出:(1)总体来看,参与体育锻炼的老年人占比约为37.37%,其中,2010~2013年老年人体育锻炼参与人数比例不高、但较为稳定;2014年开始,老年人体育锻炼参与人数比例逐渐增加。此外,随着社会变迁,阶层认同处于中上层及上层的老年人占比也在逐渐增加。(2)体育锻炼参与对老年人的阶层认同具有显著促进作用。(3)体育锻炼参与对老年人阶层认同的影响能够通过改善身体健康、心理健康和社会交往等中介作用来提升其阶层认同。(4)教育程度、房产起到了显著的调节作用。体育锻炼参与显著提升了低教育水平老年人的阶层认同,但这种提升作用随着时间的变迁在逐渐变小;拥有房产也可有效增强体育锻炼参与对老年人阶层认同的正向促进作用,但增强力度随着时间的变迁也在变小。

比较法提升实训课堂教学效果的实践探索——以高职会计专业增值税纳税申报实训项目为例

三孩政策下家庭教育期望及其生育效应

随着经济社会发展和生育观念转变,家庭生育决策进入日益理性化和成本约束的阶段。父母较高的教育期望和激烈的教育竞争影响着家庭生育意愿和行为。通过构建家庭资源约束条件下教育期望、培育策略与生育效应的分析框架,并基于大样本调查数据,考察了教育期望对家庭生育的影响效应。研究发现,家庭教育期望显著提升了生育一孩的概率,但降低了家庭生育二孩的概率,较高的教育期望引致家庭采取“质量替代数量”的生育决策。异质性分析发现,教育期望对不同阶层生育数量和再生育意愿的影响形成分化效应。较高的教育期望显著降低了中低收入阶层家庭二孩和三孩的生育意愿及行为;但在高收入阶层,较高的教育期望并未对家庭二孩和三孩的生育意愿及行为产生挤压效应。进一步研究发现,育龄夫妇受教育程度与家庭教育期望形成替代效应,育龄夫妇受教育程度越低,教育期望对二孩生育的挤压效应越大。机制分析发现,较高的教育期望显著降低了家庭的男孩偏好,说明父母对子女的教育期望越高,越重视孩子的质量而非性别和数量,带来少子化的生育决策。家庭教育期望具有一定程度的不可逆性和不同群体的趋同性,必须降低家庭的养育成本和缓解家庭养育焦虑。通过发展普惠性学前教育和义务教育,提高城乡教育均等化水平,提供多元化的市场养育服务,改善家庭的生育预期,进而提高家庭生育率。
