课程名称：定量方法 课程概述：在这门课程中，您将了解行为和社会科学中扎实科学方法的原则。我们将帮助您区分不严谨的科学与可靠的研究！课程将涵盖科学的基本原则、科学的历史与哲学、研究设计、测量、抽样以及伦理等内容。该课程相当于大学的定量研究方法入门课程，重点在于研究的诚信性。我们将以社会学、政治学、教育科学、传播科学和心理学的实例为基础进行学习。 课程大纲： 1. **开始之前…**：本模块将讨论科学方法的基本原则、历史和哲学。您将对课程的组织和内容有一个大致了解。 2. **科学方法的起源**：本模块探讨怎样通过科学方法获得知识，确保解释的准确性，了解其历史和哲学背景。 3. **科学方法**：我们将更详细地讨论经验循环和因果关系，并介绍评估研究方法质量的主要标准，包括有效性和可靠性。 4. **研究设计**：讨论常用的研究设计，包括实验设计、准实验设计和相关设计，如何应对内部效度的威胁。 5. **测量**：选择研究设计后，需要决定具体的变量测量方式。本模块将深入探讨测量的标准，自我报告测量等常用工具。 6. **抽样**：在数据收集前，研究者需要确定潜在参与者，并决定如何选择和招募他们。 7. **实践、伦理与诚信**：关注数据收集后的过程，包括数据存储和结果解释的伦理与诚信问题。 8. **复习**：没有新内容，主要是完成最后的同行评审作业，复习之前的模块内容，并准备期末考试。 9. **考试时间！**：在最终模块中，您将应用所有学习到的知识完成期末考试。考试结构与先前的练习考试完全相同，以便您做好准备。 通过这门课程，您将掌握定量研究的基本原则和方法，提高科学研究的严谨性和伦理意识。
Name:Before we get started...
Description:In this first module we'll consider the basic principles of the scientific method, its history and its philosophies. But before we start talking methods, I'll give you a broad sense of what the course is about and how it's organized. Are you new to Coursera or still deciding whether this is the course for you? Then make sure to check out the 'Introduction' and 'What to expect' section below, so you'll have the essential information you need to decide and to do well in this course! If you have any questions about the course format, deadlines or grading, you'll probably find the answers here. Are you a Coursera veteran and anxious to get started? Then you might want to skip ahead to the first course topic: the Origins of the Scientific Method. You can always check the general information later. Veterans and newbies alike: Don't forget to introduce yourself in the 'meet and greet' forum!
Name:Origins of the scientific method
Description:Science is all about gaining knowledge, coming up with the best possible explanations of the world around us. So how do we decide which explanation is the best one? How do we make sure our explanations are accurate? How do we determine we actually know something? In science we try to resolve these questions by using a set of principles and procedures called the scientific method. You need to know its historical and philosophical 'origin story' to really understand the scientific method and to fully appreciate how hard it is to apply the scientific method in the social and behavioral sciences!
Name:The Scientific Method
Description:In the first module we discussed how the scientific method developed, general philosophical approaches and the types of knowledge science aims to find. In this second module we'll make these abstract principles and concepts a little more concrete by discussing the empirical cycle and causality in more detail. We’ll see how, and in what order these concepts are implemented when we conduct a research study. We'll also consider the main criteria for evaluating the methodological quality of a research study: Validity and reliability. The focus will be on internal validity and how internal validity can be threatened.
Name:Research Designs
Description:In the previous module we discussed the empirical cycle, causality and the criteria for methodological quality, focusing on threats to internal validity. In this module we'll consider the most frequently used research designs and we'll see how they address threats to internal validity. We'll look at experimental, quasi-experimental and correlational designs, as well as some other designs you should be familiar with. To understand and appreciate these designs we will discuss some general concepts such as randomization and matching in a little more detail.
Name:Measurement
Description:Choosing a design is only the first step in the deduction phase (remember the empirical cycle?). The second step is deciding on specific ways to measure the variables of interest and disinterest. This step is extremely important, because even if we are able to perform a true double-blind experiment, if our measurement and manipulation method are of poor quality, then internal validity will still be compromised! In this module we'll look at what measurement is exactly and what the criteria for evaluating measurement are. We will also look more in-depth at self-report measures, including survey, questionnaires and tests. These methods are among the most frequently used measurement instruments in the social and behavioral sciences.
Name:Sampling
Description:In the previous two modules we discussed research designs and methods to measure and manipulate our variables of interest and disinterest. Before a researcher can move on to the testing phase and can actually collect data, there is just one more procedure that needs to be decided on: Sampling. Researchers need to determine who potential participants are and how they will be selected and recruited.
Name:Practice, Ethics & Integrity
Description:In this last content module we will focus on the part of the research process that follows data collection. The specifics of storing data and using statistics form a course topic in their own right (see the specialization courses on Basic and Inferential Statistics). For now we will focus on more general issues to do with data, interpretation and dissemination of results that relate to ethics and integrity. Some of the concepts that we discuss here will be familiar if you watched the interviews of the past modules. It might be interesting to (re-)watch these if you have the time!
Name:Catch Up
Description:In this module there's no new material to study. The only requirement in this module is that you finish up the final peer review assignment. We also advise you to take some extra time to review the material from the previous modules and to practice for the final exam. We've provided two practice exams that you can take as many times as you like. In the first one, feedback for each answer will be provided right after taking the test. We've also created some screencast videos that explain the right answers to the second practice exam in more detail.
Name:Exam Time!
Description:This is the final module, where you can apply everything you've learned until now in the final exam. The final exam is structured exactly like the practice exam, so you know what to expect. Please note that you can only take the final exam once a month, so make sure you are fully prepared to take the test. Please follow the honor code and do not communicate or confer with others taking this exam. Good luck! Once you've taken the exam why not check out the bonus material - a series of presentations on research integrity in the social sciences, presented at a special symposium at the University of Amsterdam in 2014.
Discover the principles of solid scientific methods in the behavioral and social sciences. Join us and learn to separate sloppy science from solid research! This course will cover the fundamental principles of science, some history and philosophy of science, research designs, measurement, sampling and ethics. The course is comparable to a university level introductory course on quantitative research methods in the social sciences, but has a strong focus on research integrity. We will use examples from sociology, political sciences, educational sciences, communication sciences and psychology.
