<正>课堂是学校教育的重要阵地,亦是学生获取知识的主要场所,又是净化人灵魂的殿堂。那么,上好一堂课的标准是什么呢?怎样才算一堂好课呢?一、教学目的要明确。尽管目前对一堂课的好赖,众说纷纭,各说不定,大有仁者见仁,智者见智之势,但必须要有明确的教学目的却是衡量一堂课的重要尺度之一。那么,什么是教学目的呢?所谓教学目的是指教师在一堂课中所要达到的目的。它包含两层意思:一是教学目的要定得切合实际,对知识的了解、理解、运用     

如何上好数学课

上好一堂数学课,要注重双基训练,注重教学细节;重视数学概念教学,注重能力培养;充分有效地发挥学生的主体地位,提高合作探究意识;注重课堂教学环节的完整性,整个教学环节完整,目标清晰,落实到位,学生学有所获。只有这样,才能真正创造出高效的数学课堂。     

如何上好数学课

教学设计、授课、课后回顾与反思三个方面是上好数学课的重要环节.因此数学教师要把握好上述几个环节,积极实践,勇于创新.     

如何上好数学课

现在很多老师认为数学课难上,要上好就更难了,有的抱怨学生基础差,学习又不努力,有的说数学课枯燥,学生提不起兴趣,有的认为当老师没有味道,更何况是数学老师就更没有味道了,有的觉得数学不像其他课有故事,有趣味,一天就是字母和数字,学生烦,老师也烦,还有数学作业难改,实际运用不多有些家长和学生认为学起来没有用,有些认为数学老师工作量大等等原因,针对这些理由,我认为都是一种解说,没有道理,关键是我们数学老师自己怎么想,怎么做。     

如何上好数学课

如何上好数学课?是值得每个数学教师的深思的问题.每个教师都有自己的一套教学方法.     

如何上好数学课

教学活动展开的主要场所是课堂。不管是过去、现在,还是将来,课堂教学都是我们培养学生综合能力的主要途径。课堂教学效率就是师生在单位时间内完成的教学任务,即投入的时间、精力与“产出”的关系。它是衡量课堂教学实效的一个重要指标,影响着学生作为社会公民必须具备的基本数学知识的学习、学生的可持续性发展及情感、态度、价值观和一般能力的培养。     

由康德道德教育观对现代高校德育的反思

哲学的沉思是一个民族所应有的学风。道德哲学和道德教育之间的交流与融合已成为一种发展趋势，因而对道德哲学和道德教育的思考与分析对现实德育工作有重要的意义。本文主要研析了德国古典哲学的创始人康德的道德哲学及其道德教育观，并在对其评价中从新的角度对现代的德育工作进行思考。     

与高一学生谈谈如何做好数学课堂笔记

本文通过几个方面阐明了做好数学课堂笔记的重要性,要重视方法指导,明确了记课堂笔记的教学要求,通过理清思路,使学生掌握课堂笔记的技巧,然后通过展览、评比优秀的课堂笔记,从而激发学生做好课堂笔记的积极性。     

从场论角度理解引力场的特性

本文将引力场的梯度、散度和旋度与静电场相应的三量进行了对比,从场论的角度对引力场的属性加以描述,加深了对引力场特征的认识。     

在初等数学教学中渗透数学思想方法

数学思想方法是培养学生数学素养的有效途径。在初等数学的教学过程中，可以从概念教学、定理和公式的教学、问题解决、知识的归纳总结等方面进行渗透。培养和提高学生的数学素养，形成正确的数学观，更好的从事今后的工作。     

Using three-dimensional models to teach molecular structures in high school chemistry

The purpose of this study was to compare the effects of using two- and three-dimensional model representations of molecular structures on student learning of organic chemical structures. Organic structures were taught to high school students using one of four methods of molecular representation: (1) two-dimensional textbook representations, (2) three-dimensional computer models, (3) three-dimensional ball and stick models, and (4) combination of the computer molecular models and the ball and stick models. The computer software used in this study wasMolecular Editor. Students in the combination group of using both computer and ball and stick models scored significantly higher on the retention test of isomeric identification compared to the other groups. Molecules were represented in this test in the same mode as the instructional representation. However, on a similar two-dimensional post-instructional test of isomeric identification, this group had a significantly lower mean than the other groups; the two-dimensional group had the highest mean. This difference was not observed with the two-dimensional retention test of isomeric identification. When given a two-dimensional test of isomeric construction, no significant difference was found among the group means with either the posttest or the retention test.     

Effect of project-based learning on high school students' state-mandated,standardized math and science exam performance

In a technologically driven society, math and science students in the United States are falling further and further behind their international counterparts, resulting in an influx of STEM focused, reformed K-12 schools, including schools focused on project-based learning (PBL). This article reports a study of the effectiveness of PBL on high school students' performance on state mandated standardized mathematics and science achievement measures. Manor New Tech High School is a nationally recognized model STEM school, with a diverse student population, where all instruction is delivered through PBL. Although there is ample research suggesting that PBL is advantageous for increasing STEM learning compared to conventional teaching approaches, there is a lack of studies randomly assigning students to receive PBL. Further, some of the effects observed for students attending project-based schools could be due to a self-selection bias for students or parents that choose such an alternative learning environment. This study addresses both of these concerns and found that students taught through PBL, as a group, matched performance of conventionally taught students on all science 11th grade and mathematics 9th, 10th, and 11th grade TAKS achievement measures and exceeded performance by a scale score increase of 133 for the 10th grade science TAKS measure by (B = 133.082, t = 3.102, p < .05). One possible explanation of the differences observed in this study could be the TAKS instrument used to capture student math and science achievement that interprets “real-life applications” of content differently between math and science questions. These results align with literature on the effects of PBL and deepen our understanding of these effects by providing a controlled study with random assignments to the PBL experience. Future research looking at the effect of PBL on achievement on the PISA could be beneficial in identifying benefits of PBL implementation in schools.
