Created By/Date: Allison Ball | 1/26/12
Dates Taught (Start/End): 2/3, 2/6, 2/7/12
Lesson Summary/Overview: Students will learn what makes an argument valid and identify deductive
and inductive reasoning. To begin the lesson, students will be preassessed about unit vocabulary, set up
a note outline to be used throughout the unit, and will then watch a video clip about logic. All students
will identify and explain differences in whole group practice after completing guided notes. Students
will then practice analyzing and differentiating examples in pairs and will finish independently for
homework. Students will also identify logical fallacy through real-life examples for homework. At the
conclusion of class, as an exit ticket, students will show with their hands in the shape of the triangle that
represents deductive reasoning. At least 75% of my students will accurately differentiate between
inductive and deductive reasoning on at least 75% of the homework (15 of 20 questions). By the end of
the unit, however, 100% of students will identify the differences between inductive and deductive
reasoning as well as create examples of each.
Prior to this lesson, students have completed an expository essay unit. In seventh grade, students were
introduced to inductive and deductive reasoning as well as types and techniques of propaganda.
However, students have less experience with differentiating among difficult examples (that don’t always
follow an if-then or fact-only pattern). The preassessment indicated that at least 90% of students had
heard of 70% of the unit vocabulary (10 of 14 words) but felt comfortable defining or explaining only
four of the words. This indicated that more time will need to be spent on logical fallacies and specific
types later in the unit. Also, despite inductive and deductive reasoning being explicitly taught last year,
only four students indicated remembering the terms well enough to define or explain them.
Thus, the lesson needed more explanation and differentiation between the two terms than I originally
anticipated. I expected that students would know more about argument, premise, and logic
terminology and that a third of class time would be spent in paired practice. However, students needed
much more direct instruction than anticipated. I tried to access students’ prior knowledge by referring
to our essay unit and making comparisons between the introduction and deductive reasoning (general
to specific), by using math and science examples, and by mentioning everyday, practical examples
(“Everyone else is going… Therefore, I should go, too.”). However, later in the Powerpoint, some
examples proved problematic and were structurally unsound, causing me to skip some and have to
rearrange others’ structure in order to make sense. First period helped me to realize which examples
were problematic for the rest of the classes, so a couple examples will be revisited on day two. Because
first period needed more direct instruction than anticipated and didn’t have as much time to practice in
pairs, I would cut our starter, “Giggles in the Middle,” and instead have students set up notes in their
journals as the starter. This would have freed up more time for paired practice.
On day two of the lesson, students will watch part two of the video clip, “Broken Logic,” and enter a
deeper discussion about false premises and logical fallacies. We will watch a Prezi called “The Road to
Logic” focusing on fallacy and what makes an argument faulty, and students will take guided notes.
Then, as a whole group, we will discuss inductive and deductive reasoning homework from the previous
day and make corrections. Based on what the students missed and struggled with on their homework,
we will revisit certain Powerpoint slides and notes from Friday. Additionally, we will add on to the
previous homework by analyzing each example to determine if it is a valid or faulty argument. Students
will complete this in pairs. Next, as a class, we will read an article about global warming (the first of two
over the next two days). Students will create a chart analyzing and evaluating the authors’ claim,
evidence, logical and emotional appeals/fallacies, credibility, and structure. While reading, we will stop
at four designated parts in the text to evaluate and find evidence of certain fallacies or claims. After
reading, students will fill in their chart.
The next day, students will take a quiz over Inductive and Deductive Reasoning. Then, students will read
the second article about global warming. Students will fill in the second column of their chart for this
piece and again stop at five designated points of the text to reflect, make inferences, draw conclusions,
and use textual evidence to support the author’s claims. After reading both articles and completing the
chart, the students will write an essay that is a structured argument analysis. Students will be given a
graphic organizer to scaffold prewriting ideas and will identify, analyze, and explain fallacies and appeals
used in each article as well as each author’s claim. Then, students will choose one article that is the
most credible and logical, which may not necessarily be the article supporting their personal opinion
about global warming. Students will use the textual evidence, chart, and answers to text-driven
questions to help them complete this argument analysis.
