Why Students Know the Answer but Still Lose Marks: German School Task Verbs Explained

The difference between nennen, beschreiben, erklären, begründen, vergleichen and beurteilen — and why understanding a subject is not always enough to complete a school assignment in German.

A student understands the science lesson.

They remember the facts. They can explain the topic in their first language. They may even know the relevant German vocabulary.

Then the test comes back.

The answer contains correct information, but the student has lost marks.

What went wrong?

Sometimes the problem is not what the student knows. It is what the assignment asked the student to do with that knowledge.

German school tasks frequently contain verbs such as nennen, beschreiben, erklären, begründen, vergleichen and beurteilen.

These are not interchangeable instructions.

They signal different intellectual operations: identifying information, describing observations, explaining mechanisms, supporting claims, comparing evidence and reaching justified judgments.

In German educational contexts, such instruction verbs are often called Operatoren.

Understanding them can change the way a student reads a question, constructs an answer and demonstrates knowledge.

1. One topic, six different assignments

Imagine a biology lesson about plant growth.

Students have observed two identical types of plants over several weeks.

Plant A received sufficient water and light.

Plant B received the same amount of water but much less light.

Plant A grew more vigorously. Plant B showed weaker growth and paler leaves.

The observations are deliberately simple. The purpose of this example is to examine the language of the assignment, not to present a complete scientific experiment.

Now imagine six questions about the same material.

1. Nenne zwei Bedingungen, die das Pflanzenwachstum beeinflussen.

Name two conditions that influence plant growth.

2. Beschreibe die Unterschiede zwischen den beiden Pflanzen.

Describe the differences between the two plants.

3. Erkläre, warum die Pflanzen unterschiedlich gewachsen sind.

Explain why the plants grew differently.

4. Begründe, warum Licht bei diesem Versuch berücksichtigt werden muss.

Justify why light must be considered in this experiment.

5. Vergleiche die Entwicklung der beiden Pflanzen.

Compare the development of the two plants.

6. Beurteile, ob dieser Versuch ausreicht, um eine allgemeine Aussage über Pflanzenwachstum zu treffen.

Assess whether this experiment is sufficient to support a general conclusion about plant growth.

The topic has not changed.

The available observations have not changed.

But the task has changed six times.

That is the central mechanism students need to understand.

2. Nennen: identify the requested information

The verb nennen usually asks students to name or list relevant information.

Consider:

Nenne zwei Bedingungen, die das Pflanzenwachstum beeinflussen.

A suitable answer might be:

Licht und Wasser.

Light and water.

The student identifies two relevant factors.

A long explanation is not necessarily required.

This does not mean that nennen is always easy. Students must still know which information is relevant and how many items the question requests.

But the expected response is generally different from an explanation or argument.

A student who writes an entire paragraph may be spending time on work the question did not require.

Practical reading rule: When you see nennen, first identify what must be named and how many examples or elements are requested.

3. Beschreiben: represent what can be observed

Beschreiben asks the student to describe features, developments, structures or observations.

For example:

Beschreibe die Unterschiede zwischen den beiden Pflanzen.

A suitable answer could be:

Pflanze A ist höher gewachsen und hat kräftigere Blätter. Pflanze B ist kleiner geblieben und hat blassere Blätter entwickelt.

Plant A grew taller and developed stronger leaves. Plant B remained smaller and developed paler leaves.

Notice what the answer does.

It reports differences.

It does not yet establish why those differences occurred.

That distinction matters.

Students sometimes jump immediately from observation to explanation.

But if the task asks for a description, the first requirement is to represent the observed information accurately.

Description answers: What can we observe?

It does not necessarily answer: Why did this happen?

4. Erklären: reveal the mechanism

Now consider:

Erkläre, warum die Pflanzen unterschiedlich gewachsen sind.

The student must move beyond observation.

A suitable explanation could begin:

Die Pflanzen erhielten unterschiedlich viel Licht. Licht ist eine wichtige Energiequelle für die Fotosynthese. Die geringere Lichtverfügbarkeit kann deshalb dazu beigetragen haben, dass Pflanze B schwächer gewachsen ist.

The plants received different amounts of light. Light provides the energy used in photosynthesis. Reduced light availability may therefore have contributed to Plant B’s weaker growth.

The answer connects a condition with a biological mechanism and an observed outcome.

This is different from merely stating that one plant was taller.

However, good scientific explanation also requires care.

A single observation does not automatically prove every possible cause.

The wording kann dazu beigetragen haben — “may have contributed” — acknowledges that the interpretation depends on the experimental conditions.

Explanation answers: How or why does this happen?

The student must connect facts through a meaningful relationship.

5. Begründen: support a claim with reasons

Begründen is often translated as “justify” or “give reasons.”

But students should not treat it as simply another word for erklären.

Consider:

Begründe, warum Licht bei diesem Versuch berücksichtigt werden muss.

A suitable answer:

Licht muss berücksichtigt werden, weil es das Pflanzenwachstum beeinflussen kann. Wenn die Lichtbedingungen nicht bekannt sind, lassen sich Unterschiede zwischen den Pflanzen nicht zuverlässig interpretieren.

Light must be considered because it can affect plant growth. If the light conditions are unknown, differences between the plants cannot be interpreted reliably.

Here the student is supporting a specific claim.

The claim is:

Light must be considered.

The reasons explain why that claim is justified.

The distinction between erklären and begründen is not always absolute. Real answers can contain both explanation and justification.

The important question is what the student is being asked to establish.

Erklären: What mechanism accounts for the outcome?

Begründen: What reasons support this statement, decision or conclusion?

6. Vergleichen: establish a relationship between two or more things

Students often misunderstand vergleichen as “describe A and then describe B.”

But a comparison should establish relevant similarities and differences.

Consider:

Vergleiche die Entwicklung der beiden Pflanzen.

A weak answer:

Pflanze A ist groß. Pflanze B ist klein.

Plant A is large. Plant B is small.

The information may be correct, but the comparison is minimal.

A stronger answer:

Beide Pflanzen wurden über denselben Zeitraum beobachtet und erhielten gleich viel Wasser. Pflanze A bekam jedoch mehr Licht und entwickelte sich kräftiger, während Pflanze B kleiner blieb und blassere Blätter zeigte.

Both plants were observed over the same period and received the same amount of water. However, Plant A received more light and developed more vigorously, while Plant B remained smaller and showed paler leaves.

The answer identifies a shared condition and relevant differences.

It creates an explicit relationship between the objects being compared.

A good comparison does not always require equal space for similarities and differences. The assignment may specify a particular criterion.

Practical reading rule: When you see vergleichen, identify what is being compared and according to which criteria.

7. Beurteilen: reach a justified judgment

Beurteilen requires the student to reach an assessment based on relevant knowledge, evidence or criteria.

Consider:

Beurteile, ob dieser Versuch ausreicht, um eine allgemeine Aussage über Pflanzenwachstum zu treffen.

A suitable answer might be:

Der Versuch liefert Hinweise darauf, dass die Lichtverfügbarkeit das Wachstum beeinflusst. Für eine allgemeine Schlussfolgerung reicht er jedoch nicht aus, weil nur zwei Pflanzen betrachtet wurden und weitere Einflussfaktoren sowie Wiederholungen berücksichtigt werden müssten.

The experiment provides indications that light availability affects growth. However, it is insufficient for a general conclusion because only two plants were examined, and additional influencing factors and repeated trials would need to be considered.

The student has not merely described or explained the results.

They have evaluated the strength of the evidence and reached a reasoned judgment.

This is particularly important in science, history, geography and social studies.

A justified judgment is not the same as an unsupported personal opinion.

Beurteilen asks: What conclusion is defensible, and on what basis?

8. The same knowledge can produce six different answers

The following table summarises the experiment.

This is a practical guide, not a universal marking rubric.

The exact expectations depend on the subject, educational level, wording and assessment criteria.

A single task may also combine several operations.

For example:

Beschreibe die Ergebnisse und erkläre die Unterschiede.

Describe the results and explain the differences.

That question explicitly requires two different kinds of work.

Students must notice both.

9. Why translation alone is not enough

Imagine a student whose first language is English.

They translate begründen as “explain.”

The translation may seem close enough.

But in a particular task, the teacher expects a claim to be supported with reasons, not merely a process to be described.

The student may therefore understand the vocabulary without understanding the required performance.

The same difficulty can affect learners whose first language is Ukrainian, Polish, Spanish, Chinese, Arabic or another language.

The problem is not that their first language lacks the relevant concepts.

The problem is that a familiar concept must be recognised within the conventions of a new educational environment.

This is why language instruction should go beyond word-for-word equivalence.

A student needs to understand the function of the instruction.

10. Mathematics: when the calculation is correct but the answer is incomplete

Consider a mathematics problem.

An item originally costs CHF 80.

Its price increases to CHF 100.

The question asks:

Berechne die prozentuale Erhöhung.

Calculate the percentage increase.

The answer is 25%.

Now change the instruction:

Begründe dein Ergebnis.

Justify your result.

The calculation alone is no longer sufficient.

The student should show that the increase is CHF 20 and that CHF 20 represents 25% of the original CHF 80.

The mathematical knowledge is the same.

But the expected response has changed.

This illustrates a crucial distinction:

A student may know how to calculate a result without knowing how to present the reasoning required by the assignment.

In such cases, more mathematics practice is not always the only answer.

The student may also need to learn how mathematical reasoning is expressed in German.

11. Biology, geography and history: the operator travels across subjects

These instruction verbs are not confined to German-language classes.

They appear in different school subjects, although their exact definitions and expectations can vary.

In biology, students may be asked to explain a process.

In geography, they may compare two regions.

In history, they may assess a decision using historical evidence.

In mathematics, they may justify a method or result.

The verbs remain recognisable, but the evidence and methods required are subject-specific.

For example:

Beurteile die Entscheidung.

Assess the decision.

A history answer may require historical context and sources.

A science answer may require experimental evidence and scientific criteria.

The same verb does not eliminate the need for subject knowledge.

It tells the student what kind of work must be performed with that knowledge.

12. Why a student can speak German fluently and still struggle with assignments

Conversational language and academic language serve different purposes.

In everyday conversation, students can ask for clarification, rephrase a thought or rely on context.

In a written assignment, they must identify the instruction, select relevant knowledge and produce the expected form of answer.

A student might comfortably say:

Ich glaube, Pflanze A ist besser gewachsen.

I think Plant A grew better.

But a scientific explanation may require:

Pflanze A erhielt mehr Licht. Dies könnte zu einer höheren Fotosyntheseleistung und damit zu stärkerem Wachstum beigetragen haben.

Plant A received more light. This may have contributed to greater photosynthetic activity and therefore stronger growth.

The second response demands greater precision and an explicit causal relationship.

That is part of what German educational discussions call Bildungssprache — academic or educational language.

The Canton of Zurich identifies academic language development as a responsibility across school subjects, not merely in German lessons.

13. The important diagnostic question: what exactly is missing?

Suppose a student gives an inadequate answer to a biology question.

There are several possible explanations.

Possibility A: The student does not know the biology.

They cannot explain the process even in their strongest language.

Subject instruction is needed.

Possibility B: The student knows the biology but does not understand the German question.

When the task is explained in another language, they can answer correctly.

Language comprehension is the primary obstacle.

Possibility C: The student understands the question and knows the material but cannot construct the expected response.

They may need practice with academic language, argumentation or task conventions.

These situations can produce similar marks.

But they should not automatically produce the same teaching response.

A useful assessment separates knowledge, language comprehension and answer construction.

14. A practical exercise: change only the operator

Teachers and parents can use a simple exercise.

Choose one topic the student already understands.

For example, the water cycle, a percentage calculation or a historical event.

Then create several tasks using different German instruction verbs.

Ask the student to explain what each instruction requires before answering it.

Next, let the student answer.

Compare the results.

Did the student list facts when an explanation was required?

Did they describe two objects separately instead of comparing them?

Did they express an opinion without supporting it?

Did they explain a mechanism when the task required a judgment about evidence?

The exercise reveals something that ordinary vocabulary tests may miss.

It shows whether the student can recognise the intellectual operation encoded in the task.

A useful extension

After answering, ask:

Warum hast du so geantwortet?

Why did you answer in that way?

Then:

Was wäre anders, wenn hier „begründe“ statt „beschreibe“ stehen würde?

What would be different if the instruction said “justify” instead of “describe”?

This encourages the student to make deliberate choices rather than rely on memorised response patterns.

15. What this means for children entering German-speaking schools in Switzerland

For immigrant families, this issue is particularly important.

A child may have studied mathematics, biology or geography in another country.

They may possess substantial subject knowledge.

But they must now demonstrate that knowledge through German-language school tasks.

In German-speaking Switzerland, the challenge may also include adapting to Swiss German dialects and Swiss Standard German.

These are related but distinct needs.

A child who struggles with classmates’ dialect is not necessarily unable to read a textbook.

A child who reads German fluently is not necessarily prepared to justify a mathematical solution.

And a child who receives a low mark in biology does not necessarily lack biological understanding.

Our related article, Swiss German or Standard German for School? What Immigrant Families Actually Need to Know, explores these different layers of school language in greater detail.

The practical lesson is that support should begin with identifying the actual obstacle.

16. Individual online learning: German, school subjects and the connection between them

Sometimes a student needs general German instruction.

Sometimes they need additional mathematics or biology lessons.

But sometimes the difficulty lies precisely at the intersection of language and subject knowledge.

They understand the mathematics but cannot interpret the task.

They know the biological process but cannot explain it in German.

They recognise the vocabulary but misunderstand the instruction.

In these situations, individual teaching can focus on the connection between the subject and the language used to study it.

At Levitin Language School, families can explore individual online lessons and teacher options, including language learning, school subjects and relevant combinations of language and subject support, depending on the student’s needs and teacher specialisations.

To discuss a particular learning situation, parents or adult students can contact Tymur Levitin directly on Telegram.

A useful first message includes the student’s age, current school level, language background, relevant subjects and a brief description of the difficulty.

The purpose is not to promise a universal solution.

It is to identify which kind of instruction can address the student’s actual needs.

17. What parents should ask before arranging extra lessons

Instead of asking only whether a teacher can help with German or mathematics, consider three more precise questions.

Can you distinguish between a subject knowledge gap and a language comprehension problem?

Can you teach a student how to recognise and respond to different German task instructions?

Can you use the student’s existing knowledge as the starting point instead of automatically repeating the entire subject?

These questions help establish whether the teaching approach matches the student’s actual difficulties.

18. The deeper lesson: instructions are part of knowledge in action

There is a difference between possessing information and using it appropriately.

A student can know that light influences plant growth.

But naming the factor, describing an observation, explaining a mechanism, justifying a claim, comparing results and assessing evidence are not the same activity.

Each operation requires a different response.

This principle extends beyond German.

It applies to education in many languages and to real-world communication.

Understanding a request means understanding not only its subject, but also the action the speaker expects.

German school task verbs make that distinction particularly visible.

Conclusion: the right answer depends on the question’s required action

When students lose marks despite knowing the material, the first assumption should not automatically be that they need to study the subject again.

They may need to understand the instruction more precisely.

Nennen is not the same as erklären.

Beschreiben is not the same as begründen.

Vergleichen is not the same as beurteilen.

The differences are not always rigid, and the precise requirements depend on context.

But the central principle remains:

Knowing the answer and knowing what to do with that answer are two different competencies.

Effective teaching should develop both.
