高中物理三轮复习

一轮复习

  1. 夯实基础,知识点全覆盖,力求全面细致不留死角
  2. 掌握核心物理模型及其通解法
  3. 刷透经典题型,熟知不同题型的考察方式
  4. 掌握大题模板,具备解题规范性和套路
  5. 在此基础上,建立系统化的知识体系,为二轮综合性复习做好铺垫

二轮复习策略

50分以下
  1. 一轮复习不到位,存在很严重知识漏洞;
  2. 学校的进度和自己的需求严重不匹配。目前大多数学校已经进入了二轮复习,进入了刷题讲题,知识综合,磨炼考场技巧的环节,所以不要指望跟紧老师,就能把漏洞补上;
  3. 我们只能占用二轮的时间来补一轮的漏洞。因为一轮是在织网,二轮是在演练。演练再多,网织的不好,也捕不到鱼。

所以同学们需要做到以下几点: 1. 继续按照一轮复习的节奏,分章节分专题复习,刷核心模型,刷经典题型; 2. 除了学校规定的套卷之外,尽量少刷套卷,这项工作可以放在考前一个月再进行; 3. 学会取舍和战略性放弃部分题目:如动力学多体多过程、复杂弹簧连接体、电磁场组合场+叠加场、电磁感应综合、新情境或创新题。这些暂时不属于你,有舍才有得。

必须掌握核心模型和经典题型

50-80分
  1. 部分专题存在重大漏洞,技巧和二级结论积累不够;
  2. 速度和准确度不可兼得,想做准就做不完,想做完就做不对。

所以这部分同学,需要做到以下几点: 1. 重点攻坚薄弱专题; 2. 积累并熟练运用解题技巧; 3. 通过限时训练提高速度及准确率。

专题测试来检测掌握程度

80分以上
  1. 刷近五年真题+近三年优质模拟题,把重点放在略大于高考难度的题目上,通过刷题培养题感,让自己的水平达到高考之上,升维学习,才能降维考试;

  2. 积累二级结论,提升解题速度;

  3. 培养解题的严谨性,不管是考试题还是平时的作业题,要做到会则不错,错必深究。

必会压轴题包括板块多过程,多体去返,复杂连接体,动力学+动量综合,复杂弹簧临界,电磁场综合,电磁感应综合,以及新情境类题目。

Evaluating Information:SIFT (The Four Moves)

The SIFT Method

image

The SIFT method is an evaluation strategy developed by digital literacy expert, Mike Caulfield, to help determine whether online content can be trusted for credible or reliable sources of information. All SIFT information on this page is adapted from his materials with a CC BY 4.0 license.

Determining if resources are credible is challenging. Use the SIFT method to help you analyze information, especially news or other online media.

S - Stop

Before you read or share an article or video, STOP!​

Be aware of your emotional response to the headline or information in the article. Headlines are often meant to get clicks, and will do so by causing the reader to have a strong emotional response.

Before sharing, consider:

What you already know about the topic. ​

What you know about the source. Do you know it’s reputation?

Before moving forward or sharing, use the other three moves: Investigate the Source, Find Better Coverage, and Trace Claims, Quotes, and Media back to the Original Context.

I - Investigate the Source

The next step before sharing is to Investigate the Source.

Take a moment to look up the author and source publishing the information.

What can you find about the author website creators? ​

What is their mission? Do they have vested interests? ​Would their assessment be biased?

Do they have authority in the area?​

Use lateral reading. Go beyond the ‘About Us’ section on the organization’s website and see what other, trusted sources say about the source.​ You can use Google or Wikipedia to investigate the source.

Hovering is another technique to learn more about who is sharing information, especially on social media platforms such as Twitter.

F - Find Better Coverage

The next step is to Find Better Coverage or other sources that may or may not support the original claim.

Again, use lateral reading to see if you can find other sources corroborating the same information or disputing it.​

What coverage is available on the topic? 

Keep track of trusted news sources.

Many times, fact checkers have already looked into the claims. These fact-checkers are often nonpartisan, nonprofit websites that try to increase public knowledge and understanding by fact checking claims to see if they are based on fact or if they are biased not supported by evidence.

T - Trace Claims, Quotes, and Media to their Original Context

The final step is to Trace Claims, Quotes, and Media to their Original Context.

When an article references a quote from an expert, or results of a research study, it is good practice to attempt to locate the original source of the information.​ Click through the links to follow the claims to the original source of information. Open up the original reporting sources listed in a bibliography if present

Was the claim, quote, or media fairly represented?

Does the extracted information support the original claims in the research? ​

Is information being cherry-picked to support an agenda or a bias?​

Is information being taken out of context?​

Remember, headlines, blog posts, or tweets may sensationalize facts to get more attention or clicks. ​Re-reporting may omit, misinterpret, or select certain facts to support biased claims. If the claim is taken from a source who took it from another source, important facts and contextual information can be left out. Make sure to read the claims in the original context in which they were presented.

When in doubt, contact an expert – like a librarian!​.

Think Again

image

MENTAL FLEXIBILITY

Thinking again can help you generate new solutions to old problems and revisit old solutions to new problems.

COGNITIVE LAZINESS

We favor the comfort of conviction over the discomfort of doubt, and we let our beliefs get brittle long before our bones. We are afraid of rethinking answers and the idea of rethinking.

INDIVIDUAL RETHINKING:HOW TO OPEN OUR MIND TO RETHINK

THINK LIKE A SCIENTIST

Run experiments to test hypotheses and find knowledge

AVOID THINKING LIKE

  • PREACHER We deliver sermons to protect and premote our ideals.
  • PROSECUTOR We recognize flaws in other peoples reasoning to prove them wrong and win our case.
  • POLITICIAN We campaign and lobby for the approval of our comstituents.

BEWARE OF THE MOUNT STUPID

The danger lies not only in a lack of competence, but also in an overestimation of competence.

GET INTO TASK CONFLICTS

Conflicts of ideas and opinions. Prevent it from turning into an emotional conflict. Well-performing groups do not hesitate to present opposing perspectives.

ATTAIN A CONFIDENT HUMILITY

CONFIDENCE

Armchair quarterback syndrome

COMPETENCE

Impostor syndrome

HAVE A CHALLENGING NETWORK

A group of people we trust to point out our blind spots and help us overcome our weaknesses.

INTERPERSONAL RETHINKING

HOW TO ENCOURAGE OTHERS TO RETHINK THEIR CONCEPTS

DEBATE LIKE A DANCE

A good debate is not a battle, it’s more like a dance without choreography.

LEARN TO DEBATE

Find a common denominator, focus on few arguments, avoid getting into an attack-defense spiral, ask lots of questions.

EXERCISE COUNTERFACTUAL THINKING

Imagine how the circumstances of our lives could have unfolded differently.

PRACTICE MOTIVATIONAL INTERVIEWS

Ask open-ended questions, listen reflectively, affirm the other person’s desire and ability to change.

COLLECTIVE RETHINKING

HOW TO CREATE COMMUNITIES OF LIFELONG LEARNERS

AVOID BINARY BIAS

When it comes to complex issues, knowing the other side’s opinions isn’t enough. The opposing arguments do not change our view. Generates polarization.

TEACH HOW TO CHECK THE FACTS

Teach children to question information instead of simply consuming it. Reject rank as a proxy for reliability

TEACH HOW TO THINK LIKE A SCIENTIST

Identifying problems, developing hypotheses and devising their own experiments to test them.

BUILT A CULTURE OF LEARNING

Learning culture, organizations innovate more and make fewer mistakes. Psychological safety with accountability. Performance Culture, short-term result, but people stop innovating, making mistakes and sharing ideas.
