Eritrea Grade 8 National Examination common mistakes
Eritrea Grade 8 National Examination · Understand the traps and how to avoid them.
In a word problem with mixed units, the candidate converts only the first measurement or ignores units entirely and adds or subtracts the raw numerals.
Practice is often done on bare numbers, so unit conversion is not automatic; under time pressure the candidate treats all quantities as interchangeable.
What to do instead
Require a written unit line before every calculation: list each quantity with its unit, convert all to one unit, then compute. Assign five mixed-unit drills weekly and mark the unit line separately.
In multi-step mathematics, the candidate writes only the final answer, skipping intermediate lines, then loses method marks or repeats an arithmetic slip.
Past practice rewards answer-only work, and weak working-memory load makes several steps hard to hold without writing.
What to do instead
Enforce a three-line minimum for multi-step items: given, operation, result. Mark process and answer separately, and use checkpoint boxes so each line is checked before moving on.
In reading comprehension, the candidate copies a sentence containing a keyword from the passage instead of answering an inference question.
Keyword matching is a fast test-taking habit, and inference questions are less practised than literal retrieval.
What to do instead
Have the candidate label each question as literal or inference, underline the evidence, then answer in their own words using a because statement. Practise five inference items per session.
In English grammar, subject-verb agreement fails when a phrase separates the subject from the verb or when a collective noun is used.
The candidate follows the nearest noun rather than the head noun, and first-language patterns may reinforce the error.
What to do instead
Teach a routine: bracket the subject, cross out prepositional phrases, identify the head noun, then choose the verb. Use ten sentence-correction items daily with the routine written beside each item.
In science practical questions, the candidate writes a conclusion as an observation, for example stating that a plant grew because it received water when asked what was observed.
Everyday reasoning blends what was seen with what it means, and the observation-inference distinction is often not made explicit in class.
What to do instead
Use a two-column observation/inference table. Require observations to come only from senses or instruments and conclusions to cite recorded data. Model one wrong and one correct answer.
In heat and matter questions, the candidate uses heat and temperature interchangeably and states that heat rises.
Everyday language treats the terms as synonyms, and the underlying particle model is insecure.
What to do instead
Use a concept card: heat is energy transferred; temperature measures average kinetic energy. Practise corrected sentence stems and demonstrate with melting/boiling data rather than verbal definitions alone.
On map or timeline questions, the candidate reads only the title and guesses, ignoring key, scale, direction, and labels.
Map and timeline skills are often taught briefly, and under exam pressure the candidate looks for a quick clue rather than applying a procedure.
What to do instead
Require a written checklist before answering: title, key, scale, compass direction, labels. Do three map or timeline questions per week with the checklist completed first.
In cause-and-effect social studies questions, the candidate names a single event without explaining the mechanism, for example saying famine caused migration without push and pull factors.
Revision focuses on dates and events rather than processes, so the candidate lists causes instead of linking them.
What to do instead
Teach a because, therefore, as a result chain. Sort cause and consequence cards, then write one full model answer. Require every cause to be followed by a mechanism and a consequence.
In mother-tongue essay writing, the candidate uses a spoken register with slang or loanwords, inconsistent spelling, and no paragraph breaks.
Oral fluency is transferred directly to writing, and editing for register and orthography is rarely practised.
What to do instead
Use a register checklist and a ten-minute plan with one topic sentence per paragraph. Provide a teacher-edited model, then require a second draft that changes at least three register or spelling items.
In mother-tongue comprehension and vocabulary items, the candidate gives an everyday synonym that does not fit the formal context of the passage.
Vocabulary is learned as single-word equivalents rather than in context, so tone and collocation are ignored.
What to do instead
Teach a context-clue routine: read the surrounding sentence, identify the tone, substitute the candidate word, and check whether it fits. Keep word-family and collocation lists rather than isolated synonyms.
