D2.Soc.2.9-12: Defining Social Context as the External Forces That Shape Behavior

In plain English: D2.Soc.2.9-12 is the C3 Framework sociology indicator for grades 9-12 that asks students to define social context in terms of the external forces that shape human behavior. Students name those forces, such as norms and social pressure, groups, institutions, economic conditions, the historical period and the physical setting, and trace them in historical accounts and federal data.

Overview

D2.Soc.2.9-12 asks students to define social context in terms of the external forces that shape human behavior. Social context is the set of conditions outside a person that come from living in society: the norms and social pressure people face, the groups they belong to, the institutions and rules around them, economic conditions, the historical period and the physical setting as people have organized it. These forces are external because they exist outside any one person and were mostly in place before that person arrived, yet they shape what the person does.

The lesson uses three sources. In a 1915 English translation, the French sociologist Emile Durkheim describes society's demands on its members and the respect that makes people obey (Source 1). Samuel Henry Prince's 1920 study of the Halifax, Nova Scotia, explosion of December 6, 1917 shows social pressure, group feeling, circumstance and climate shaping behavior after a disaster (Source 2). A U.S. Census Bureau table of the median age at first marriage from 1890 to 2025 lets students see how behavior shifts with the historical period. Students classify forces in invented scenes, sort internal from external explanations and analyze the Census data.

Learning Objectives

By the end of this lesson, students will be able to:

  • Define social context as the set of external forces that shape human behavior
  • Name and give examples of six kinds of external force: norms and social pressure, groups, institutions, economic conditions, historical period and physical setting
  • Distinguish external forces from internal causes such as personality or mood
  • Identify external forces in Durkheim (1915) and Prince (1920) and support each with a quotation
  • Compute and interpret changes in Census data on the median age at first marriage, without claiming causes the data cannot show

Prior Knowledge Required

Students should already be comfortable with:

  • The sociological perspective and how it differs from other social sciences D2.Soc.1.9-12
  • Reading a data table and a line graph RH.9-10.7
  • Computing a difference and reading a median

Lesson Procedure

60-70 minutes of class time across 5 phases.

  1. Warm-Up5-10 minutes

    Warm-Up Prompt

    "Think of a typical high school student's morning. Name one thing that student does because of a rule, a schedule or other people's expectations. Would the student still do it if they lived alone on an island?"

    List a few answers: catching a bus at a set time, dressing for school, greeting a family member, checking a phone because friends expect quick replies. Ask what each one depends on outside the student: a bus company, a school, a family, a friend group. Tell students that sociologists call this web of outside influences the social context, and today's task is to define it precisely.

  2. Direct Instruction20 minutes

    Definition. Social context is the set of external forces that shape human behavior: influences that come from outside the individual, from the society the person lives in. An external force is not the same as an internal cause such as personality, mood or a physical need, although the two often work together. A norm is a shared expectation about how to act; an institution is an organized, lasting structure such as a school system or a body of law. The table sorts external forces into six kinds; the grouping and examples are written for this page, and many real situations involve several kinds at once.

    Six kinds of external force (definitions and examples written for this page)
    Kind of forceWhat it includesEveryday example
    Norms and social pressureShared expectations about how to act, and the pressure to follow themStudents stand when the school song plays, even when no teacher is watching
    Groups and relationshipsFamily, friends, teams and other groups a person belongs to or identifies withA teenager joins the debate club because her friend group already belongs
    Institutions and rulesOrganized, lasting structures such as schools, laws, religion, the economy and governmentA state law sets the age at which teenagers may drive alone
    Economic conditionsJobs, prices, wages and the resources available to peopleWhen a town's factory closes, more teenagers look for part-time work
    Historical periodThe time a person lives in, with its events, technology and common ways of lifeTeenagers in 1925 and in 2025 face different choices about school and work
    Physical setting, as people organize itClimate, distance and the built environment of roads, buses and housingA new bus route lets students reach the library after school

    Reading 1. Emile Durkheim (1858-1917) was a French sociologist. This passage comes from his book on religion, translated into English in 1915, where he argues that society holds great power over its members. Read it only for what it says about society's pressure on individuals; the lesson takes no position on religion. Two words to know: servitors are servants, and privation means going without things one needs.

    [...] Now society also gives us the sensation of a perpetual dependence. Since it has a nature which is peculiar to itself and different from our individual nature, it pursues ends which are likewise special to it; but, as it cannot attain them except through our intermediacy, it imperiously demands our aid. It requires that, forgetful of our own interests, we make ourselves its servitors, and it submits us to every sort of inconvenience, privation and sacrifice, without which social life would be impossible. It is because of this that at every instant we are obliged to submit ourselves to rules of conduct and of thought which we have neither made nor desired, and which are sometimes even contrary to our most fundamental inclinations and instincts.

    Even if society were unable to obtain these concessions and sacrifices from us except by a material constraint, it might awaken in us only the idea of a physical force to which we must give way of necessity, instead of that of a moral power such as religions adore. But as a matter of fact, the empire which it holds over consciences is due much less to the physical supremacy of which it has the privilege than to the moral authority with which it is invested. If we yield to its orders, it is not merely because it is strong enough to triumph over our resistance; it is primarily because it is the object of a venerable respect.

    Emile Durkheim, translated by Joseph Ward Swain, Source 1: Durkheim on society's demands and its moral authority (1912; English translation 1915) (1912; this edition 1915). Public domain (published 1915). Source text.
    • Why a force is external: Source 1, paragraph 1

      Durkheim says we must follow "rules of conduct and of thought which we have neither made nor desired." Explain what makes such rules external forces.

      Result: The rules existed before the person and do not depend on the person's wishes; they come from the society around them. A student did not invent the school schedule or the custom of shaking hands, yet both shape what the student does every day. That is the core of the definition: social context is made of forces outside the individual.

    • Naming the force (invented scene)

      Invented: in a town where most families have two working parents, the middle school opens at 7:15 a.m. so parents can drop children off on the way to work, and many students arrive sleepy. Name the external forces.

      Result: Economic conditions (parents' work hours), an institution and its rules (the school's opening time) and family relationships (who drives whom). The sleepiness is internal, but its timing is set by the context. One behavior, three kinds of external force.

    • Social pressure without a rule: Source 2, paragraph 1

      Prince writes that taking refugees into homes "became the thing to do." How does he define social pressure here?

      Result: "The thing to do is social pressure. It may be unwilled and unintended but it is inexorable." No law ordered families to shelter strangers; the pressure came from copying what others did ("Imitation is the foundation of custom"). An external force can work without anyone planning it.

    • The historical period as a force: Census table

      Men's median age at first marriage was 24.6 in 1920 and 22.8 in 1950. Find the change and say what kind of force a sociologist would look for.

      Result: 22.8 - 24.6 = -1.8, a fall of 1.8 years. Because the change shows up across a whole country's population, a sociologist looks for forces of the historical period, such as changes in jobs, schooling or norms, and then tests each idea with more evidence. The table alone does not show which force caused the change.

  3. Guided Practice15 minutes

    Reading 2. On the morning of December 6, 1917, a French munitions ship, the Mont-Blanc, collided with the Imo, a Norwegian ship chartered for Belgian relief, in the harbor of Halifax, Nova Scotia, and exploded. Prince, who lived in Halifax and observed the aftermath himself, wrote this study as his doctoral dissertation at Columbia University. He counted "Two thousand slain, six thousand injured, ten thousand homeless." His 1920 study asked how the city's people behaved and reorganized. In paragraph 2, consciousness of kind means the feeling of belonging with people one sees as similar.

    [...] Then the idea spread of taking the refugees into such private homes as had fared less badly. Imitation is the foundation of custom. It became the thing to do. The thing to do is social pressure. It may be unwilled and unintended but it is inexorable. It worked effectively upon all who had an unused room. Many sheltered upwards of a dozen for weeks; some, more.

    In the homes and shelters association of the like-minded soon came about through consciousness of kind. At first it was a very general consciousness which seemed to draw all together into a fellowship of suffering as victims of a common calamity. [...] Men, women and little children lay side by side in the large sleeping rooms and "shared each other's woes," for "the consciousness of kind allays fear and engenders comradeship." Then followed requests for changes of location in the dormitories, and for changes of seats at the dining tables. As various shelters sprang up, the religious element appeared. Applications came for transfers from Roman Catholic institutions to Protestant stations and vice versa. Even the politically congenial were only too ready to segregate when occasion offered.

    [...]

    Men at best are largely creatures of circumstance. Innumerable causes, small and great, conspire to incite social action. But in catastrophe the control of circumstantial pressure becomes almost sovereign in extent. The conditions it brings about, while often delaying measures of individual relief, account very largely for the rapidity of organization. While they limit they also provoke effort. The common danger constrains great numbers to "overlook many differences, to minimize many of their antagonisms and to combine their efforts." [...]

    [...]

    In consequence of otherwise unendurable conditions, the most rapid repairs were made to all habitable houses or those possible of being made so. [...] The climate decided the question of reconstruction in favor of temporary structures; for it was a time of year when prompt rebuilding was out of the question. Climatic conditions also seriously delayed the arrival of relief supplies, allowed but scanty provision for many, kept some from the depots of relief, or from surgical aid; and others standing in line in the bitter cold. [...] But it speeded and spurred the workers to prevent the maximum of exposure and neglect. It called imperatively for the most effective system, and many of the workable methods were hit upon under the stress of storm.

    Prince also printed the weather for the week after the explosion, from the St. John (N.B.) observatory and the Halifax station. The figures below are copied from his table; he does not name the temperature unit, and he gives Friday's snow in inches.

    1. Find the forces. For each paragraph of Source 2, name the kind of external force Prince describes and quote the phrase that shows it.
    2. Pressure without a rule. Does paragraph 1 say that anyone ordered families to take in refugees? What does your answer show about how social pressure works?
    3. Circumstance. Paragraph 3 says circumstantial pressure both limits and provokes effort. Find one example of each in paragraphs 3 and 4.
    4. Data. Using the weather table, on how many of the seven days did snow fall?
  4. Independent Practice15 minutes

    Students work with Table 2, copied from the U.S. Census Bureau's Table MS-2, Estimated Median Age at First Marriage, by Sex: 1890 to Present (December 2025 release). The median is the middle value: roughly, half of people who marry for the first time do so before that age and half after. The Bureau estimates it from survey and census data on who has ever married, which is why the table calls it an estimated median. The Census Bureau's notes say the 1890-1940 figures come from the decennial censuses and later figures from the Current Population Survey, that estimates from 2019 on include same-sex married couples, and that 2025 figures reflect a change in population estimates. The table shows selected years; Diagram 1 plots them.

    Table 2. Median age at first marriage, selected years (U.S. Census Bureau, Table MS-2)
    YearMenWomen
    189026.122.0
    192024.621.2
    194024.321.5

    199026.123.9
    201028.226.1
    202530.828.4

    Task: (1) For one period of your choice, compute the change for men and for women. (2) Write two hypotheses, each naming one external force from the six-kind table that might help explain the change, and label them as hypotheses. (3) For each hypothesis, name one kind of evidence that could test it. Students should discuss groups and trends only, never their own family's choices.

  5. Closure5-10 minutes

    Exit ticket: "Define social context in one sentence. Then name two external forces that shape a typical student's school day."

    Teacher notes. (1) Source 1 comes from Durkheim's sociological theory of religion. The lesson uses only his claim about social pressure and takes no position on any religious belief; if students ask, explain that Durkheim was describing how religion works in society, which believers and nonbelievers may interpret differently. (2) Both authors write "men" for people in general, as was usual in their time. Prince's paragraph 2 describes shelter residents asking to move by religion and politics; treat this as a historical observation about group feeling in 1917, not as a judgment of any group. The death and injury figures are Prince's 1920 estimates. (3) Census marriage data describe the whole population, not any student's family. Keep discussion at the level of groups and trends, and do not ask students about their parents' marriages. (4) The six-kind table and the scenes in Activities 1 and 2 are written for this page.

Differentiation Strategies

For Struggling Students

  • Give the six-kind table with an icon or color for each kind, and have students mark each quotation in Sources 1 and 2 with the matching color
  • Pre-highlight one sentence per paragraph of Source 2 that names a force
  • Provide a sentence frame: "___ is an external force because it comes from ___, not from the person, and it shaped ___ by ___."

For Advanced Students

  • Read Prince's full chapter III in the source file and find two forces he names that this page leaves out, such as leadership or discussion
  • Compare Durkheim's claim that people obey society mainly out of respect with an invented example where obedience comes mainly from fear of punishment, and decide which fits better
  • Plot every year in the full Census Table MS-2 (linked through the Census Bureau) and mark the switch from census to survey data in 1947

Assessment Guidance

What to Look For

Strong answers define social context as forces outside the individual that come from society, name the specific kind of force (norm, group, institution, economic condition, historical period or physical setting), show how it shaped a behavior, and support the claim with a quotation or a correct figure. Watch for students who list internal causes such as laziness or personality as social context, who treat a trend in the Census table as proof of one cause, or who describe a whole group's behavior as if every member acted the same way.

Classroom Activities

3 Activities

1

Force Finder: Six Invented Scenes

15 minGroups of 3-4, rotating

Six stations each hold one invented scene. At each station, groups name the behavior, the main external force behind it and its kind from the six-kind table, and one internal factor that might also matter.

The 6 Scenes (invented)

  1. At a new school, students who sit at the front of the cafeteria are teased, so new students learn to sit at the back.
  2. Three cousins all choose the same college because the family has gone there for two generations.
  3. A city raises the minimum age for working at night, and fewer 15-year-olds apply for evening shifts.
  4. When a town's largest employer cuts jobs, families eat at restaurants less often.
  5. Students in 1955 wrote letters to faraway friends; students today send messages within seconds.
  6. After a new bike lane opens, more students ride to school on dry days.

Answer Key

1: norms and social pressure. 2: groups and relationships (family tradition). 3: institutions and rules (a city law). 4: economic conditions. 5: historical period (the technology of the time). 6: physical setting as people organize it. One scene for each of the six kinds. Internal factors vary, for example shyness in scene 1 or a love of cycling in scene 6.

Discussion

Which scene involves more than one kind of force? Scene 2 also involves an institution (the college), and scene 6 also involves a government decision to build the lane. Real behavior is usually shaped by several forces at once.

2

Inside or Outside? Ten Reasons for Arriving Late

15 minPairs

Pairs get ten invented cards, each giving one reason why a student, Sam, often arrives late to first period. They sort the cards into internal causes and external forces, then discuss the cards that are hard to sort.

The 10 Cards (invented)

  1. Sam finds it hard to wake up early.
  2. The city bus that stops near Sam's home was moved 15 minutes later this fall.
  3. Sam's parent starts a work shift at 7:30 and drops a younger sibling off first.
  4. Sam often loses track of time while getting ready.
  5. Road construction closed the shortest route to school.
  6. In Sam's friend group, arriving a few minutes late is treated as normal.
  7. The school does not mark students late until 10 minutes after the bell.
  8. Sam feels anxious about the first-period class.
  9. Sam works a closing shift at a grocery store three nights a week.
  10. Sam likes to sleep in.

Answer Key and Discussion

External forces: 2 (physical setting and a transit institution), 3 (family relationships and economic conditions), 5 (physical setting), 6 (norms of a group), 7 (an institution's rule) and 9 (economic conditions). Internal causes: 1, 4, 8 and 10. That is six external and four internal. Discussion: is card 1 really internal if Sam goes to bed late because of the closing shift in card 9? Durkheim's point in Source 1 is that outside rules can become part of how a person feels and acts, so the line between inside and outside is not always sharp.

3

Reading a Century of Census Data

20 minPairs

Pairs use Table 2 and Diagram 1 to describe how the median age at first marriage changed and to propose, as hypotheses only, external forces that might help explain the change.

Steps

  1. Mark the lowest median for each sex in the table and the year it occurred.
  2. Divide the century into two or three periods by direction of change (falling, rising) and compute the change for men and for women in each period.
  3. For one rising period, write two hypotheses, each naming a kind of external force, for example "Hypothesis: more years of schooling (an institution) may delay marriage." Label each one a hypothesis.
  4. For each hypothesis, name one source of evidence that could test it, such as Census data on years of schooling.
  5. Read the table notes in Independent Practice and write one caution about comparing years.

Variation: The Gap Between Men and Women

Instead of the trend, pairs study the difference between men's and women's medians in each year and describe how it changed. They still label any explanation a hypothesis.

Homework: Mapping the Forces Around a Behavior

Directions: Source 1 is printed in Direct Instruction, Source 2 and the weather table in Guided Practice, and Table 2 in Independent Practice. Quote every source you use with its paragraph number, and show your work for computations. Discuss groups and trends only; do not write about your own family's private choices.

Part 1: Reading the Data (Problems 1-3)

  1. Using Table 2, find the gap between men's and women's median age at first marriage in 1890 and in 2025 (men's median minus women's). Did the gap grow or shrink? Name one kind of external force that a sociologist might investigate to explain the change, and label it a hypothesis.
  2. Using Table 2, find the change in women's median age at first marriage from 1990 to 2010 and from 2010 to 2025. In which of the two periods did it rise faster per year? Show the per-year rates.
  3. Using Prince's weather table, find the total snowfall on the days with snow, adding the three printed figures (Prince gives the unit, inches, only for Friday; treat all three as inches). Then quote one sentence from Source 2, paragraph 4 that shows the weather shaping what people did.

Part 2: Defining and Applying (Problems 4-6)

  1. Write your own one-sentence definition of social context. Test it on three invented situations of your choice, one sentence each, and name the kind of external force in each.
  2. On paper only, make a force map of an ordinary school day for a typical student at an invented school: list five behaviors and, for each, one external force and its kind. Do not use real names.
  3. Durkheim (Source 1, paragraph 2) says people obey society "primarily because it is the object of a venerable respect," while Prince (Source 2, paragraph 3) says that "Men at best are largely creatures of circumstance." Write a paragraph comparing the two kinds of external force and give one invented example of each.

Frequently Asked Questions

10 Questions

What does D2.Soc.2.9-12 mean?

D2.Soc.2.9-12 asks high school students to define social context in terms of the external forces that shape human behavior. Students should be able to say what social context is, name the kinds of outside forces it includes and show how those forces shape what people do.

What is social context in sociology?

Social context is the set of conditions outside a person that come from living in society. It includes norms and social pressure, groups and relationships, institutions and rules, economic conditions, the historical period and the physical setting as people organize it.

What are some examples of external forces?

A school's start time, a state law on teen driving, a friend group's expectations, a local job market, the technology of an era and a new bus route are all external forces. Each comes from outside the individual and shapes behavior, even though people respond to it in different ways.

Is social context the same as the environment?

Not quite. The physical environment is one part of social context when people's lives are organized around it, as with roads, housing or winter weather that decides how a city rebuilds. Social context is broader: it also includes norms, groups, institutions, the economy and the historical period.

If social context shapes behavior, do people still make their own choices?

Yes. External forces shape and limit choices but rarely decide them completely; two people in the same context can act differently. Durkheim's claim that we must follow rules "we have neither made nor desired" is a strong version of the idea that students can test and argue with.

Why does the lesson use a disaster as an example?

In everyday life, external forces are easy to overlook. Prince argued that in catastrophe "the control of circumstantial pressure becomes almost sovereign," so the Halifax explosion of 1917 makes forces such as social pressure, group feeling and climate unusually easy to see.

Why use Census data on the age at first marriage?

Because the data describe a whole population over more than a century, they show how behavior shifts with the historical period, one kind of external force. The table describes trends for groups, not any one family, and it shows change without proving its cause.

How is D2.Soc.2.9-12 different from D2.Soc.3.9-12?

D2.Soc.2.9-12 is about defining social context and naming its forces. D2.Soc.3.9-12 goes a step further and asks students to identify how that context influences particular individuals, for example how a family, school or neighborhood shapes one person's choices.

How is D2.Soc.2.9-12 assessed?

Here, through quotation-based questions on Durkheim and Prince, classification of new invented scenes by kind of force, computations with the Census table, and short answers that define social context and separate external forces from internal causes. The rubric also rewards labeling explanations of trends as hypotheses.

Is a passage from Durkheim's book on religion appropriate for a public school class?

Yes, when it is used as a social science text. The excerpt is about society's pressure on its members; the lesson takes no position on any religious belief, and a teacher note explains how to answer questions about the book's subject.
