About This Topic

Synthesis is the 'highest level' of research. It is the ability to take information from multiple, often conflicting, sources and 'weave' them together to create a new, more nuanced understanding of a topic. In this topic, students learn to move beyond 'Source A says X, Source B says Y' to 'While Source A argues X, Source B provides evidence for Y, suggesting that the truth is actually Z.'

This unit aligns with CCSS standards for integrating information into the text selectively to maintain the flow of ideas, avoiding plagiarism and following a standard format for citation. Synthesis is what turns a 'report' into an 'essay.' This topic is best taught through 'mapping' activities and 'collaborative writing' where students must find the 'connections' between disparate pieces of evidence.

Key Questions

1. How can the publication date affect the relevance and credibility of a source?
2. Analyze how an author's credentials or affiliations impact the trustworthiness of a source.
3. Differentiate between primary and secondary sources and their appropriate use in research.

Learning Objectives

• Evaluate the credibility of online sources by analyzing author expertise, publication date, and potential bias.
• Compare and contrast the information presented in primary and secondary sources for a given research question.
• Explain how an author's affiliations or stated purpose can influence the objectivity of a source.
• Synthesize information from multiple sources to support a specific claim, citing evidence appropriately.

Before You Start

Identifying Main Idea and Supporting Details

Why: Students need to be able to identify the core message of a text before they can evaluate its credibility or relevance.

Basic Internet Search Skills

Why: Students must be able to locate and access various online sources to practice evaluation techniques.

Key Vocabulary

Credibility	The quality of being trusted and believed. In research, this refers to a source's reliability and accuracy.
Bias	A prejudice in favor of or against one thing, person, or group compared with another, usually in a way considered to be unfair. Identifying bias is crucial for objective analysis.
Primary Source	An original document or artifact created at the time under study, such as a diary, photograph, or interview.
Secondary Source	A document or work that analyzes, interprets, or summarizes information from primary sources, such as a textbook or scholarly article.
Relevance	The degree to which a source is pertinent and applicable to the research question. Outdated information may lack relevance.

Watch Out for These Misconceptions

Common Misconception

Synthesis is just a 'summary' of multiple sources.

What to Teach Instead

A summary is 'looking back' at what was said; synthesis is 'looking forward' to a new idea. Use a 'Recipe' analogy: a summary is a list of ingredients; synthesis is the 'cake' you make by combining them in a specific way.

Common Misconception

If sources disagree, one of them must be 'wrong.'

What to Teach Instead

Often, both sources are 'right' from their own perspective. A 'Nuance' workshop helps students see that 'conflicting' evidence is an opportunity to explore the 'complexity' of a topic, rather than just choosing a 'winner.'

Active Learning Ideas

Inquiry Circle: The 'Synthesis' Web

Groups are given three short articles with different perspectives on a topic (e.g., 'The Impact of Social Media'). They must draw a 'web' showing where the articles 'agree,' 'disagree,' and 'overlap.' They then write one 'synthesis sentence' that covers all three views.

Think-Pair-Share: The 'Missing' Link

Students are given two 'facts' from different sources. They pair up to find the 'missing link', the logical connection that explains how these two facts relate to each other. They share their 'connection' with the class.

25 min·Pairs

Role Play: The 'Panel' Discussion

Three students act as the 'authors' of three different sources; a fourth student acts as the 'Moderator.' The Moderator must ask questions that force the authors to 'respond' to each other's ideas. The class then writes a summary of the 'consensus' or 'conflict' they heard.

Real-World Connections

• Journalists at major news organizations like the Associated Press or Reuters must rigorously evaluate sources, distinguishing between official statements, eyewitness accounts, and opinion pieces to report accurately.
• Medical researchers developing new treatments must critically assess studies published in journals, considering the funding sources and potential conflicts of interest of the authors to ensure the validity of findings.
• Historians researching the Civil Rights Movement use a variety of sources, including letters from activists, government documents, and contemporary newspaper articles, to construct a comprehensive and nuanced narrative.

Assessment Ideas

Quick Check

Provide students with two short articles on the same current event from different sources (e.g., a reputable news site and a blog with a clear political leaning). Ask students to write 2-3 sentences identifying which source is likely more credible and why, citing specific elements like author credentials or publication date.

Exit Ticket

On an index card, have students list one question they would ask to evaluate the credibility of a website and one question they would ask to determine the relevance of a source to a specific research topic.

Peer Assessment

Students bring a source they are considering for a research project. In small groups, each student briefly explains their source and why they chose it. Group members ask clarifying questions about the source's credibility and relevance, offering one suggestion for improvement or verification.

Frequently Asked Questions

What is the difference between 'analysis' and 'synthesis'?

Analysis is 'breaking something down' into its parts to see how it works. Synthesis is 'putting parts together' to create something new. In research, you analyze individual sources so that you can synthesize them into a final argument.

How do I organize a 'synthesized' paragraph?

Don't organize by 'source' (one paragraph for Source A, one for Source B). Organize by 'idea.' Start with a topic sentence about the *idea*, and then use evidence from *multiple* sources within that same paragraph to support it.

What are 'transition words' for synthesis?

Use words that show relationship: 'Similarly,' 'Conversely,' 'In contrast,' 'Building on this idea,' 'While Source A focuses on X, Source B adds the perspective of Y.' These words are the 'glue' that holds your synthesis together.

How can active learning help students master synthesis?

Synthesis is a 'puzzle-solving' task. Active learning, like the 'Synthesis Web' or 'Panel Discussion,' forces students to physically 'see' the connections between sources. When they have to 'be' the authors and respond to each other, the 'dialogue' between sources becomes real, making it much easier to write about in their final paper.
