CHSE Odisha Elective Home Science common mistakes
CHSE Odisha Elective Home Science · Understand the traps and how to avoid them.
Listing only the name of a nutrient deficiency disease (e.g., 'kwashiorkor', 'beriberi', 'night blindness') without stating the deficient nutrient, the vulnerable group, and two preventive dietary measures, even when the question carries 4-5 marks.
Candidates memorise disease names from one-line textbook headings and treat the question as a recall label rather than a structured answer; they do not notice the mark allocation implies several distinct scoring points, so they stop after the first fact that comes to mind.
What to do instead
Before writing, count the marks and allocate one point per mark. For every deficiency disease, prepare a five-part card: deficient nutrient, clinical signs, most vulnerable age/physiological group, two locally available preventive foods, and one national programme or supplementation measure. Practise writing these cards as full sentences within a time limit so the habit becomes automatic.
Calculating a meal's energy and protein by adding raw ingredient weights or by using the wrong food composition values, and omitting the cooked-weight or edible-portion correction, so the computed nutritive value is far from the expected figure.
Candidates learn food composition tables as isolated numbers but never practise the full calculation chain (raw amount → edible portion → cooked yield → nutrient per 100 g → total), and under exam pressure they skip steps or mix values from different food groups.
What to do instead
Build a one-page calculation template and use it for every practice problem: state the raw quantity, convert to edible portion, apply the cooked-weight factor if given, multiply by the table value per 100 g, and total. Do at least ten timed calculations covering cereals, pulses, milk and green leafy vegetables, and always show each step in the answer so partial credit is available.
Describing developmental milestones in vague terms such as 'the child grows and becomes social' instead of giving the approximate age, the specific observable behaviour, and the implication for caregiving.
Milestone content is often studied as a narrative rather than as an age-linked checklist, so candidates remember the general direction of development but cannot attach it to a stage or connect it to feeding, play or stimulation practices.
What to do instead
Make a four-column table (age band, motor, language, social-emotional) and fill it from the prescribed syllabus, then add a fifth column linking each milestone to a caregiver action. Answer milestone questions by naming the domain, the age range and one example behaviour, then one caregiving implication.
Confusing fibre properties with fabric finishes, or naming a weave without explaining its effect on durability, shrinkage or comfort, so the answer lists terms such as 'twill', 'mercerisation' and 'sizing' in one undifferentiated list.
The textiles syllabus moves quickly from fibre to yarn to fabric to finish, and candidates memorise the vocabulary of each stage without building the causal chain from fibre property to fabric performance to end use.
What to do instead
For each fibre, write a chain: fibre property → yarn/fabric structure → finish applied → performance characteristic → suitable garment or household use. When a question asks about a weave or finish, always state what it does to the fabric and why that matters for a specific product, rather than defining the term alone.
Answering a resource-management question with only a definition of a principle such as 'planning' or 'simplification of work', without applying it to a concrete household situation, a time or energy saving, and a stated limitation.
Principles are memorised as abstract statements and candidates do not practise transferring them to the case-based wording the paper uses, so they reproduce the definition and stop, missing the application marks.
What to do instead
Practise a fixed three-part answer structure for every principle: define it in one sentence, apply it to a named household task with a measurable saving (minutes, steps, cost), and note one condition under which it fails. Keep a bank of ten household scenarios (festival cooking, cleaning a two-room flat, budgeting a monthly income) and rehearse applying each principle to them.
Treating interior decoration as a list of furniture names, so answers on colour schemes, lighting or space planning never mention the room's function, the users' needs, or the principles of design being applied.
Candidates study furnishing items and styles visually and reproduce names, but the exam rewards design reasoning; without practice in justifying choices, the answer reads as an inventory rather than a design solution.
What to do instead
For every design answer, state the room and its users, the function, the principle applied (balance, rhythm, proportion, emphasis), and the practical justification (safety, maintenance, ventilation, cost). Draw a simple labelled layout plan in pencil where the question allows it, since a labelled sketch often earns marks that prose alone does not.
Writing extension answers that recommend a single mass-media channel or a lecture as the method for every situation, without analysing the audience, their literacy level, the available resources, or how adoption will be followed up.
Teaching methods are memorised as a list of options with advantages and disadvantages, but candidates do not practise the selection step, so they name a method rather than choosing and defending one for a described community.
What to do instead
Use a selection grid: audience characteristics, message complexity, literacy, cost, reach and feedback needed. For each practice scenario, choose two methods, justify the choice against the grid, and describe one follow-up mechanism such as a demonstration plot, a home visit schedule or a village meeting review. Always mention how adoption will be monitored.
In the practical examination, presenting a dish or garment that meets the recipe or pattern requirement but has no stated cost, no nutritive or functional justification, and no record of the work process in the file.
Candidates rehearse the product repeatedly but leave the written record and the oral justification to the last minute, and they underestimate how much of the practical mark depends on the file, the costing and the ability to explain decisions.
What to do instead
Maintain the practical file continuously with dated entries: aim, recipe or draft, costed ingredient or material list with local prices, method, observations, modifications made and reasons. Rehearse a two-minute spoken justification covering cost, nutrition or fit, hygiene or finish, and one improvement you would make next time.
Choosing a project or field-study topic that is too broad ('malnutrition in India') and then presenting only library material with no local data, no method and no analysis.
Candidates equate a project with an essay and select topics from textbook chapter titles; they do not realise that marks come from a defined sample, a described tool, tabulated findings and a discussion linked to the syllabus.
What to do instead
Narrow the title to one locality and one variable (for example, breakfast practices of Class IX students in a named school). Write the method section first: sample size, selection, tool, and how data will be tabulated. Collect at least a small real data set, present it in a table or simple graph, and discuss each finding against a syllabus concept.
In the viva, giving one-word answers or answering a question about a different topic than the one asked, and being unable to explain why a particular ingredient, stitch or measurement was chosen.
Viva preparation is often neglected because candidates assume marks rest on the product; nervousness then produces short answers, and without rehearsed reasoning the candidate cannot connect the product to the underlying concept.
What to do instead
Prepare and rehearse answers to predictable viva questions: why this recipe or design, what the nutritive or functional value is, what went wrong and how you corrected it, what you would change, and which syllabus concept it demonstrates. Practise with a peer who asks follow-up questions, and answer in complete sentences that name the concept before the example.
