Social Studies Semester Exam Review

The instructor reviews the main examinable ideas across four areas: population, cities, global economic activity, and climate and the environment. The recurring advice is to study the textbook carefully, memorize key concepts and examples, and practise adapting textbook questions rather than only memorizing their answers.

Exam Overview and Study Approach

• The instructor estimates 26 multiple-choice questions, roughly divided as follows:
  • Population: 9
  • Cities: 6
  • Global topics: 6
  • Environment: 5
• There may also be about 7 short-answer questions: approximately 1 on population, 2 on cities, 3 on global topics, and 1 on the environment.
• Work through the textbook alongside the review, paying particular attention to graphs, maps, city names, and case studies.
• For end-of-unit questions, consider how the teacher could change the wording or details to create a new exam question.
• The subtitles are auto-generated, so some names and phrases—especially a few city examples—may be imperfect.

1. Population

Population Distribution

• Review the distribution of the world’s population and the natural and human factors that influence where people live. The instructor especially emphasizes natural factors.
• Learn the names and locations of relevant cities and regions.
• In Korea, understand how population distribution changed:
  • Before industrialization, population was concentrated in a different pattern, described in the lecture with reference to Uiju and Yeongil Bay.
  • Industrialization increased the populations of large and industrial cities.
  • Rural-to-urban migration contributed to population decline in agricultural and mountainous areas.

Population Migration

• Study why people migrate and the main patterns of international migration.
• For migration within Korea, review the periods and patterns highlighted in the lecture, including the 1960s, 1970s, and 1990s, as well as migration during the Japanese colonial period and migration to Japan.
• Understand the effects of population inflow and outflow:
  • What changes occur in areas receiving people?
  • What problems can arise in areas losing people?

Population Issues

• Distinguish the population challenges of developed and developing countries, and know possible responses. Be ready to interpret relevant graphs and data.
• For Korea, focus on low birth rates and population aging: their causes or consequences as covered in the textbook, the problems they create, and possible measures to address them. The instructor identifies these as likely short-answer material.
• Memorize the age thresholds for classifying an aging society:
  • Aging society: people aged 65 and over exceed 7% of the population.
  • Aged society: they exceed 14%.
  • Super-aged society: they exceed 20%.

2. Cities and Urbanization

City Characteristics and Examples

• Review the characteristics of cities and be able to connect well-known landmarks with their locations. One example emphasized is the Sagrada Família in Barcelona.
• Learn eco-city examples along with their countries. The lecture names Reykjavík (Iceland), Quito (Ecuador), Freiburg (Germany), and Curitiba (Brazil).
• The instructor also highlights examples of livable cities. Several city names in this part of the subtitles are unclear, so check the textbook’s examples rather than relying only on the auto-generated transcript.

Urban Structure and Urbanization

• Know the concepts used to describe internal urban differentiation, including:
  • City center and sub-center
  • Central and peripheral areas
  • Development-restricted zones
  • Satellite cities
• Understand how accessibility and land prices help explain differences among urban areas.
• Review urbanization in both developed and developing countries, including how their patterns differ.
• Study urban problems in developed and developing countries and possible responses. The lecture refers to examples such as Detroit and a case in Brazil.

Textbook Areas Singled Out

The instructor specifically points students to:

• Pages 133–134 for low birth rates and population aging
• Pages 142–143 for examples of livable cities
• Page 151 for urbanization and cities in developed countries

3. Global Economic Activity

Agriculture and Multinational Corporations

• Review how the corporatization and globalization of agriculture affect economic activity.
• Understand what multinational corporations are, why they expanded, and how improved transportation and communications, the WTO, and FTAs relate to their growth.
• Know the international division of labor:
  • Headquarters and research facilities are often located in developed countries.
  • Production facilities may be located in developing countries where land and labor costs are lower.
• Be able to discuss both potential benefits and costs of multinational corporations’ arrival, including job creation and technology transfer, as well as possible negative effects.

Service Industries, Tourism, and E-Commerce

• Distinguish consumer services from producer services.
• Review tourism and distribution-related topics, including fair or responsible practices as presented in the textbook.
• Understand why service industries can create employment. The instructor emphasizes that services can be difficult to standardize because they vary by customer, and that providing more services often requires more labor.
• Pay particular attention to tourism and e-commerce, including the e-commerce material highlighted around page 170.

4. Climate and Environmental Issues

• Distinguish natural and human causes of climate change, with particular attention to greenhouse gases and global warming.
• Review the effects illustrated in maps and other materials, including:
  • Melting glaciers and rising sea levels, with Tuvalu cited as an example
  • Floods, droughts, desertification, and coral bleaching
• Learn the environmental agreements covered in class, including their names and the circumstances in which they were established; the subtitles do not identify specific agreements.
• Understand how pollution-intensive industries, polluting factories, and electronic waste move between places.
• Review the environmental problems and proposed responses discussed in class, including waste, genetically modified organisms, and fine dust.

Short-Answer Priorities

The instructor highlights these areas as especially important for written responses:

1. Korea’s low birth rate and population aging: problems and possible solutions.
2. Well-known city examples, especially cities presented as livable.
3. Urban differentiation and how urbanization develops.
4. Differences in urbanization and urban problems in developed and developing countries.
5. Multinational corporations: division of labor and the effects of their expansion.
6. Service industries, tourism, and e-commerce, including why services generate employment.
7. Environmental problems and ways to address them.
