MATSEC SEC Environmental Studies common mistakes
MATSEC SEC Environmental Studies · Understand the traps and how to avoid them.
Defining a term such as 'sustainable development' or 'biodiversity' by repeating the phrase in different words rather than stating its components (e.g. intergenerational equity, variety at genetic/species/ecosystem level).
Candidates memorise the label but not the definition, so under time pressure they write a circular sentence that gains no marks against a mark scheme that awards credit per component.
What to do instead
For every key term, prepare a three-part card: a one-line definition, two named components, and one local Maltese example. Practise writing the definition in under 30 seconds and check it against the component list.
Answering a 'describe' question with a bare list, or a 'list' question with long prose, ignoring the command word.
Candidates read the topic rather than the instruction verb, and exam technique is rarely drilled separately from content revision.
What to do instead
Underline the command word before writing. Build a one-page table of command words (state, list, describe, explain, compare, evaluate, suggest) with the sentence structure each demands, and rehearse converting a list of four points into four 'because' sentences.
Giving a generic global example (Amazon deforestation, polar bears) when the question asks about Malta or the Mediterranean, or when a local case would earn the contextual marks.
Textbooks and online revision sites are internationally sourced, so candidates absorb foreign case studies and never link them to the local syllabus context.
What to do instead
Maintain a 'Malta file' of six to eight named local cases with figures: a Natura 2000 site, a reverse-osmosis desalination plant, a waste-management facility, a scheduled building or ODZ development dispute, a marine protected area, and a local renewable-energy scheme. Attach each to the relevant syllabus topic.
Writing 'it is bad for the environment' or 'it causes pollution' as the whole explanation, with no mechanism, named pollutant, or consequence.
Candidates know the direction of the effect but not the causal chain, and mark schemes award marks for the intermediate steps.
What to do instead
Practise chain diagrams: source, release, pathway, receptor, effect, mitigation. For example, fertiliser application, nitrate leaching, groundwater, drinking-water exceedance, treatment cost. Write each chain out as a full sentence before the exam.
Confusing the greenhouse effect with ozone depletion, or treating 'global warming' and 'climate change' as identical, and mixing their causes and consequences.
Both are atmospheric-chemistry topics taught close together, both involve gases and the word 'global', and both appear in media coverage with overlapping imagery.
What to do instead
Build a two-column contrast table: principal gases, location of the effect (troposphere versus stratosphere), primary mechanism, main international agreement (UNFCCC/Paris versus Montreal Protocol), and one consequence of each. Test yourself by sorting ten statements into the correct column.
Treating renewable energy or recycling as automatically sustainable, with no mention of limitations such as intermittency, land take, embodied energy, or contamination of recyclate.
Simplified campaigning messages present these as unqualified goods, and candidates reproduce the slogan instead of evaluating it.
What to do instead
For each 'green' solution on the syllabus, prepare one advantage and one genuine limitation with a number attached (capacity factor, land area per MW, cost per tonne of collection). In evaluation questions, always include a counterpoint sentence beginning 'However...'.
Omitting units, or giving a bare number, in calculations of energy use, waste per capita, ecological footprint, or percentage change, and not showing the working.
Candidates focus on getting an answer and skip the presentation, but method marks and unit marks are awarded separately from the final value.
What to do instead
Adopt a fixed layout: formula, substitution with units, answer with units, one-line comment on what the result means. Rehearse with past-paper-style data, including a percentage-change and a per-capita question, until the layout is automatic.
Describing a data figure or graph as 'going up' or 'high' without quoting values, axes, or trends, and without comparing two series.
Candidates read graphs as pictures rather than as evidence, and are not trained to extract specific figures under time pressure.
What to do instead
Use a three-step routine for any data response: quote the figure with its unit and year, state the trend or comparison, then offer a reason or implication. Practise on a table of Maltese waste or energy statistics until quoting figures becomes habitual.
Leaving structured questions blank or writing one word where four marks are available, because the candidate cannot recall the 'textbook' answer.
Fear of being wrong plus a belief that partial answers earn nothing leads to abandoned marks; in practice mark schemes credit any valid, relevant point.
What to do instead
Count the marks and write that many distinct points. If recall fails, reason from first principles using the chain-diagram method, and never leave a line empty: a relevant definition, example, or consequence can still score.
Running out of time on the extended or essay question because earlier short answers were over-written, leaving the highest-tariff section unfinished.
Candidates allocate time by interest rather than by mark weighting, and rarely rehearse full papers under timed conditions.
What to do instead
Before starting, write the minute allocation beside each section (roughly one minute per mark, plus reading time). Do at least two full timed papers, and practise a 20-minute essay plan: introduction, three developed points with local examples, counterpoint, conclusion.
