How FLASH marking transformed my feedback in modern foreign languages lessons

How a new marking system reduced workload and raised standards in Melody Valois’ modern foreign languages (MFL) classroom.

How can we give students high-impact feedback without drowning in marking? As a GCSE and A-Level Spanish teacher, I faced this challenge daily, until I discovered FLASH Marking.

Inspired by the Education Endowment Foundation (EEF) trial in English, I adapted FLASH for modern foreign languages – creating a feedback system that’s fast, focused and formative. Drawing on top-band descriptors from the AQA A-Level Spanish marking scheme and cognitive load theory, I developed a toolkit that helped students think more like linguists, reflect on their progress and grow in confidence – without increasing my workload.

This article shares how I tailored FLASH for AQA GCSE and A-Level Spanish, and why it could be worth exploring in your own setting.

Adapting FLASH for MFL

In AQA GCSE Spanish

In my adaptation for AQA GCSE Spanish, I created a feedback grid aligned with the key skills assessed in the 90-word and 150-word writing tasks. Each code links to a specific linguistic feature or success criterion, many drawn from A-Level descriptors, to challenge students and encourage them to aim higher.

Example codes include:

• T – Use of five different tenses
• OJ – Opinion Justified
• SoE – Ser vs Estar confusion
• ACC – Accuracy
• CSS – Complex Structures and Sentences
• PA – Personal response
• AV – Ambitious Vocabulary
• EX – Your answer needs developing

The system works as follows:

• I mark students’ work using these codes, highlighting strengths and targets.
• I model the codes using real student examples.
• Students use the codes for self- and peer-assessment.
• The codes inform their target setting and revision strategies.

For A-level Spanish

For A-level Spanish cultural essays, I developed a separate set of codes aligned with the AQA mark scheme’s assessment objectives. AO3 covers accuracy, complexity and range of language; and AO4 covers critical and analytical response to the text or film.

• AO3 codes include T (Tenses), SUBJ (Subjunctive), CSS (Complex Structures), and AV (Ambitious Vocabulary).
• AO4 codes include EV (Evaluation), TH (Themes), SC (Social Context), and AQ (Analysis of Quote).

This structure scaffolds metacognitive understanding: students see what they’ve done well, why it matters, and how to improve within a clear academic framework.

Insights from the classroom

During my lessons, I explored how FLASH Marking could support cognitive load management and improve behaviour and motivation. In one lesson, students analysed two essays, one high-scoring and one mid-range, using the AQA mark scheme. They identified key features, discussed misconceptions and worked together to improve the weaker essay. This process helped them build mental models of success and engage in reflective dialogue.

I also refined my resources to reduce split attention, using dual coding and simple visuals. With feedback from my colleagues, I made the FLASH feedback codes easier to read and select by putting them on a single A4 pastel-coloured sheet. Using IRIS Connect, I recorded and reviewed my explanations, focusing on clarity and pacing. This helped me improve my instructions and ensure that students could process new information without overload.

Final thoughts

Marking in MFL can often feel repetitive or overwhelming, but FLASH Marking gave me a way to maintain high standards without compromising my time or wellbeing. More importantly, it gave my students a toolkit for understanding their progress and becoming more independent, reflective learners.

If you’re exploring ways to make feedback more meaningful and manageable in MFL, FLASH Marking might be worth a try. I’d love to connect with others trialling similar approaches.
