Aichi Entrance Social Studies common mistakes
Aichi Entrance Social Studies · Understand the traps and how to avoid them.
When calculating time differences, candidates simply subtract or add the difference in longitude without considering the standard meridian of each country's time zone, and they forget that the International Date Line causes a date change.
They memorize the formula '15° = 1 hour' but do not understand that standard time is based on the standard meridian, and they confuse the direction of the date change at the International Date Line.
What to do instead
For each country, confirm the standard meridian (e.g., Japan: 135°E, India: 82.5°E, China: 120°E) and calculate the time difference as (longitude difference)/15. When crossing the International Date Line, remember that going east (from Japan to the Americas) subtracts a day, and going west adds a day. Practice with specific examples.
When reading a map, candidates confuse latitude and longitude, or they cannot correctly determine the cardinal directions (north, south, east, west) on a map without a north arrow.
They are not accustomed to the convention that on maps north is up, and they do not understand that latitude lines run horizontally and longitude lines run vertically.
What to do instead
Always check the map's legend and orientation. Use the rule 'latitude = horizontal, longitude = vertical' and practice reading coordinates of specific cities (e.g., Tokyo 35°N, 139°E). Draw a simple grid and mark directions.
When describing the characteristics of a region, candidates list only climate or only industry, failing to connect multiple factors such as climate, religion, language, and economy.
They memorize fragmented knowledge and do not practice integrating it, so they cannot see the relationships between factors.
What to do instead
Use a framework: for each region, create a table with columns for climate, religion, language, main industries, and population, and write a short paragraph linking them. For example, 'In West Asia, dry climate → Islam → oil economy'.
In history, candidates memorize only the names of eras and people, and cannot explain the causal relationships between events (e.g., the cause and effect of the Taika Reform).
They study by rote memorization of isolated facts without understanding the historical context and connections.
What to do instead
Create a timeline for each period and write 'cause → event → result' for key events. For example, 'Sui's invasion → dispatch of envoys to Sui → introduction of Chinese culture → Taika Reform'.
In modern history, candidates confuse the order of events (e.g., the order of the opening of Japan, the Meiji Restoration, and the promulgation of the Constitution) and cannot explain the relationship between domestic politics and international relations.
They do not grasp the overall flow of history and study events in isolation.
What to do instead
Make a chronological table with columns for year, domestic events, and international events, and check the sequence. For example, '1853 Perry arrives → 1868 Meiji Restoration → 1889 Constitution promulgated'.
In civics, candidates memorize the names of rights but cannot explain the difference between basic human rights and the rights of the people, or they confuse the roles of the National Diet, Cabinet, and courts.
They study the Constitution as a list of articles without understanding the actual functioning of the separation of powers.
What to do instead
Create a diagram of the separation of powers with checks and balances (e.g., the Diet designates the Prime Minister, the Cabinet dissolves the House of Representatives, the courts review constitutionality). For human rights, classify them into equality rights, freedom rights, and social rights with examples.
In economics, candidates confuse the roles of the Bank of Japan and the government, or they cannot explain the mechanism of supply and demand and price determination.
They do not understand the basic concepts of the market economy and study only by memorizing terms.
What to do instead
Draw a supply and demand graph and explain how price is determined. For monetary policy, compare the Bank of Japan's role (issuing currency, controlling money supply) with the government's role (fiscal policy). Use current examples such as interest rate changes.
When reading statistics or graphs, candidates look only at the numbers and do not check the units, year, or source, leading to misreading (e.g., confusing percentages with absolute numbers).
They are not accustomed to carefully reading the axis labels and notes on graphs.
What to do instead
Always check the title, unit, year, and source of the graph. Practice by comparing two graphs and pointing out differences. For example, 'The population is increasing, but the percentage is decreasing'.
In essay questions, candidates write only their impression or list multiple opinions without a clear conclusion, failing to answer the question.
They do not understand the structure of a logical essay (claim → evidence → conclusion) and have little practice writing.
What to do instead
Practice the format: 'I think X because of reason A and reason B. Therefore, X.' Use specific data or historical facts as evidence. For example, 'I agree with the idea that the Constitution should be revised because...'
When relating multiple materials, candidates treat each material independently and cannot find common points or contradictions.
They lack practice in cross-referencing materials and do not know how to extract relationships.
What to do instead
Practice by comparing two materials (e.g., a map and a graph) and writing a sentence that connects them. For example, 'The map shows that the population is concentrated in coastal areas, and the graph shows that industry is also concentrated there.'
