    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for correctly identifying and explaining the three main stages of search engine operation: crawling, indexing, and ranking.
    • Assess ability to construct a search query using at least one Boolean operator (AND, OR, NOT) to narrow or broaden results.
    • Check for evidence of evaluating website credibility, such as checking domain authority, author credentials, or publication date.
    • Look for demonstration of safe searching habits, e.g., using HTTPS sites, avoiding suspicious links, or clearing browsing data.
    • Award credit for clearly explaining the basic process of how a search engine finds and lists web pages (e.g., crawlers, indexing, relevance ranking).
    • Award credit for demonstrating the use of targeted keywords and advanced search operators (e.g., quotation marks, minus sign) to refine results.
    • Award credit for applying a basic framework to assess website credibility, such as checking the author, date, domain, and cross-referencing information.
    • Award credit for identifying and describing safe browsing practices, including recognising secure connections (HTTPS), avoiding suspicious downloads, and not sharing private details on unverified sites.
    • Describe how search engines crawl, index, and rank pages.
    • Use advanced search operators to refine results.
    • Evaluate sources for credibility and bias.
    • Apply safe search practices to protect personal data.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always cross-reference facts from multiple reputable sources to confirm accuracy before using them in research.
    • 💡Use quotation marks around phrases to search for exact matches, which reduces irrelevant hits and saves time.
    • 💡Before clicking a link, hover over it to preview the URL and ensure it leads to a trusted domain.
    • 💡Always read the full URL before clicking—look for slight misspellings or unusual domains that signal fake sites.
    • 💡When evaluating sources, use a simple mnemonic like 'CRAAP' (Currency, Relevance, Authority, Accuracy, Purpose) to structure your evidence.
    • 💡Practice using multiple search terms and combinations; explain your choice of keywords in your assessment to show deliberate research skills.
    • 💡Keep a log of your research steps, including safe-search settings and site evaluations, as this can serve as direct evidence for your portfolio.
    • 💡Practice using Boolean operators (AND, OR, NOT).
    • 💡Bookmark reliable sources for future reference.
    • 💡Always cross-check information from multiple sources.
    • 💡When answering questions about online safety, always give specific examples, such as 'using two-factor authentication' or 'checking for HTTPS in the URL'. This shows deeper understanding.
    • 💡For programming tasks, focus on the logic of your algorithm rather than memorising code. Draw flowcharts or write pseudocode to demonstrate your thought process.
    • 💡In practical assessments, ensure you save your work regularly and in the correct file format. This simple habit can prevent losing marks due to technical issues.

    Common Mistakes

    Common errors to avoid in your coursework

    • Assuming that all search results are equally reliable and not verifying the information source.
    • Using overly broad or vague keywords that lead to irrelevant or overwhelming results.
    • Ignoring the importance of privacy, such as sharing personal information on unsecured sites or not using incognito mode when appropriate.
    • Accepting the first search result as the most accurate or authoritative without further scrutiny.
    • Failing to distinguish between organic results and paid advertisements, leading to biased or commercial information.
    • Neglecting to verify the currency of information, resulting in the use of outdated or superseded data.
    • Clicking on links from unfamiliar sites or pop-ups, increasing the risk of malware or phishing attacks.
    • Relying solely on the first search result without checking reliability.
    • Using vague search terms that yield irrelevant results.
    • Ignoring privacy settings and sharing personal information.
    • Misconception: 'Digital skills are only for people who want to be programmers.' Correction: Digital skills are essential in almost every job today, from retail to healthcare, and this course covers a broad range of practical abilities.
    • Misconception: 'Online safety is just about not talking to strangers.' Correction: It also includes protecting your devices from malware, using strong passwords, and understanding privacy settings on social media.
    • Misconception: 'Spreadsheets are just for accountants.' Correction: Spreadsheets are used in many roles for data analysis, budgeting, and project management, making them a versatile tool.
