Common Mistakes Students Make in American Sign Language and How Feedback Helps

Key Takeaways

Definitions

Receptive skills are the ability to understand signs, facial expressions, and movement when someone else is signing.

Expressive skills are the ability to produce signs clearly and accurately using correct handshape, movement, palm orientation, location, and non-manual signals such as facial expression.

Why American Sign Language can feel harder than parents expect

For many families, American Sign Language looks approachable at first because students can begin learning useful signs quickly. A teen may come home after the first few weeks able to fingerspell names, introduce themselves, and sign basic classroom phrases. That early success is real, but high school ASL becomes more demanding as students move beyond memorizing vocabulary and into grammar, fluency, and visual accuracy.

This is one reason the common American Sign Language mistakes students make can be confusing to parents. A student may study hard, know the quiz words, and still lose points during a live signing assessment. In ASL, communication depends on more than remembering the right sign. Students also need to use the right facial expression, sign in the correct location, keep movements controlled, and follow ASL sentence structure rather than English word order.

Teachers often assess ASL through video submissions, partner conversations, receptive quizzes, and in-class performances. Those tasks can reveal mistakes that would not show up on a traditional written worksheet. A teen might recognize a sign on flashcards but produce it unclearly in conversation. Another student may understand isolated signs but struggle when a classmate signs a full sentence at natural speed.

From an instructional standpoint, this makes sense. Students in world languages develop skill through repeated input, guided correction, and active use. In ASL, that process is especially visible because the language is expressed through the body. Feedback matters because students cannot always hear or feel their own errors the way they might notice a mispronounced word in a spoken language class.

Common ASL mistakes in high school and what they look like in class

In grades 9-12, ASL courses often shift from basic signs to more precise communication. That is where patterns of error become easier to spot. Below are some of the most common issues teachers see.

Using English grammar instead of ASL structure

One of the biggest hurdles is word order. Students who think in English may sign a sentence exactly as they would say it aloud. For example, a teen might try to sign, “I am going to the store tomorrow,” in English order. In ASL, time markers often come earlier, and the sentence may be organized more visually. A teacher may ask the student to restructure the sentence rather than simply swap one sign for another.

This is a normal stage in language learning. Students often rely on their first language while they are still building comfort with a new one. Helpful feedback sounds specific, such as, “Your signs are correct, but your sentence order is following English.” That kind of correction gives the student something clear to revise.

Weak or inconsistent facial expressions

Parents are sometimes surprised to learn that facial expression is not just extra emotion in ASL. It carries grammar and meaning. A yes or no question, a WH-question, surprise, uncertainty, and emphasis can all depend on non-manual signals. A student who signs the hand movements correctly but keeps a flat expression may sound incomplete or confusing to a teacher or fluent signer.

In class, this often shows up when a teen does well on vocabulary recognition but seems stiff during presentations. They may know the signs for “where,” “go,” and “you,” but if their eyebrows, eye gaze, and expression do not match the question, the sentence does not fully communicate what they intend.

Handshape errors that change meaning

Small differences in handshape can create a completely different sign or make a sign hard to understand. High school students commonly confuse signs that look similar at a glance, especially when they are still building fine motor control and visual memory. If a teacher repeatedly marks a sign as unclear, the issue may not be vocabulary knowledge at all. It may be handshape precision.

This is where guided practice is valuable. Students often need someone to slow the sign down, compare the incorrect version to the correct one, and have them repeat it several times with immediate correction.

Signing too fast, too small, or outside clear signing space

Teens often rush when they are nervous. During a video assignment or in-class dialogue, they may sign too quickly, clip movements, or let signs drift out of the usual signing area. Teachers may then comment that the signing is difficult to read even if the student technically chose the right vocabulary.

ASL teachers frequently coach students to make signs readable before trying to make them fast. Clear production is usually a better sign of proficiency than speed alone.

Overreliance on fingerspelling

When students forget a sign, many fall back on fingerspelling. That can be useful in moderation, but overusing it can interrupt flow and signal that vocabulary is not yet secure. In beginner and intermediate classes, teachers often want students to build direct sign meaning rather than constantly translating from English and spelling around gaps.

If your teen says, “I know what I want to say, but I freeze,” they may need more retrieval practice, not just more memorization. Organized review and targeted feedback can help them access signs more automatically.

What feedback changes in an ASL course

Feedback is especially powerful in ASL because many errors are visual and physical. Students do not always notice when their palm orientation is off, their movement path is too short, or their facial expression does not match the sentence type. Without correction, those habits can stick.

In a strong high school world languages classroom, feedback is usually concrete and observable. A teacher might say, “Your location is too low,” “Use raised eyebrows for that question,” or “That sign needs a repeated movement.” This kind of coaching helps students connect performance with meaning.

Parents may hear their teen say that ASL feels awkward or that they keep getting corrected on tiny details. It helps to know that those details are part of the language system, not random preferences. Precise feedback supports real communication.

There are several ways feedback helps students improve:

• It prevents repeated errors. If a student practices a sign incorrectly for weeks, it becomes harder to change later.
• It makes invisible problems visible. Video review, teacher modeling, and one-on-one correction help students see what they could not catch on their own.
• It builds receptive and expressive skills together. When students compare their signing to a teacher model, they strengthen both production and understanding.
• It lowers guesswork. Instead of feeling that ASL grades are subjective, students learn exactly what to improve.

Many teens benefit from recording short practice clips at home and comparing them to class models. Others improve when they receive live correction and can immediately try again. If your child tends to shut down after making mistakes, supportive feedback can also help with confidence. Families looking for broader academic habits around confidence and persistence may find useful ideas in confidence-building resources.

What can parents watch for in grades 9-12 ASL?

High school students are often balancing ASL with demanding schedules, other language or elective courses, and performance pressure. A teen may appear to be doing fine because they can complete homework, but certain signs may suggest they need more targeted support.

Watch for patterns such as these:

• Your teen memorizes vocabulary lists but struggles in live conversations.
• They do well on written gloss or matching activities but lose points on video assignments.
• They avoid eye contact, facial expression, or larger signing movements because they feel self-conscious.
• They say the teacher signs too fast, even after studying.
• They understand isolated signs but miss meaning in full sentences or short stories.
• They rely heavily on English translation instead of thinking in ASL structure.

These patterns are common in ASL classes and do not mean a student is not capable. They usually point to a skill gap in fluency, receptive processing, motor accuracy, or confidence with expressive language.

Teachers often see these same patterns in class. For example, a student may perform well with a familiar partner but struggle when responding to a new signer. Another may know unit vocabulary on food, school, or family but become confused when the teacher signs a narrative that combines classifiers, time markers, and non-manual signals. Those are normal developmental steps in language learning, and they respond well to guided practice.

How guided practice and individualized support help

Because ASL is performance-based, many students need more than independent review. Flashcards alone may not fix an inaccurate handshape or a missing facial marker. Guided instruction gives students a chance to practice with correction in the moment.

In tutoring or one-on-one support, the work can be very specific to the course. A student might:

• Rehearse an upcoming dialogue assessment and get feedback on pacing, clarity, and expression.
• Practice receptive skills by watching short signed clips at a manageable speed, then gradually increasing complexity.
• Learn how to break down confusing signs by handshape, location, movement, and palm orientation.
• Compare English-based sentence attempts with more natural ASL structure.
• Review teacher comments from a graded video and turn them into a focused practice plan.

This kind of individualized help matters because students make different kinds of errors. One teen may need support with visual grammar. Another may need confidence using signing space. A third may understand class content but benefit from slower, repeated receptive practice. Personalized instruction can meet the student where they are instead of treating every mistake the same way.

Educationally, this aligns with how skill-based learning develops. Students improve fastest when practice is targeted, feedback is immediate, and the next step is clear. That is true in music, athletics, and world languages, and it is especially true in ASL.

Helping your teen practice ASL at home without taking over

Parents do not need to know ASL fluently to support steady progress. What helps most is creating conditions for consistent, low-pressure practice tied to actual course demands.

You might encourage your teen to:

• Record short videos and review them for one focus area at a time, such as facial expression or signing space.
• Practice unit vocabulary in phrases and sentences rather than as isolated signs.
• Use teacher rubrics when preparing for expressive assessments.
• Ask their teacher which errors are affecting comprehension most.
• Keep a short list of signs or grammar points that need reteaching after quizzes or presentations.

If your teen is frustrated, try asking course-specific questions instead of broad ones. “Was the issue vocabulary, sentence order, or facial expression?” is more useful than “Did you study enough?” That shift helps students reflect on the actual skill they are building.

It is also helpful to normalize revision. In ASL, redoing a video after feedback is not a sign of failure. It is part of learning how to communicate more clearly. Many students become more independent once they understand exactly what to watch for and how to self-correct.

Tutoring Support

When ASL starts to feel harder than expected, extra support can give students a more manageable path forward. K12 Tutoring works with families to provide individualized academic help that matches the pace and expectations of a student’s course. In a class like American Sign Language, that can mean targeted practice with expressive skills, clearer feedback on recurring mistakes, and structured support for quizzes, conversations, and video assessments. The goal is not perfection. It is stronger understanding, better communication, and growing confidence over time.
