Some of the Worst Instructional Mistakes Teachers can Make

Many teachers spend a career doing the wrong things. What's worst is that some are aware that much of what they do is poor teaching and teachers continue because they are unable to adapt to new ways, or some are just "wrong-spirited" and seem immune to new ideas.

#1. Grading formative assessments. Homework, for example, is generally for diagnosis and practice. It has two serious defects as a gradable assessment: (i.) it can be -- and often is -- copied; and (ii) it often violates the principle of grading something  that has not yet been thoroughly taught -- that's why it is designated as a "formative" assessment.

Likely, the most common reason for grading it is personal deriving from the notion that the teacher told students to do it and feel as though the student disobeyed by not doing it. The grade is a punitive action for the disobedience and a reward for compliance.

Perhaps equally common is the belief that "If I don't grade it, they won't do it." That is due to the fact that many students have been    "taught" that school is about grades and learning is secondary. Students often do not understand that well-conceived homework is about learning and not grades. After receiving a few grades for homework students expect it. 

Finally, many teachers believe that homework develops responsibility. Actually, responsibility develops homework. The seeds of responsibility are planted and nourished at home and responsible students do homework because their parents engendered positive habits. Students with parents who don't nourish children get penalized.

#2. Over-Reliance of Punishment and Rewards. Teachers often face a genuine dilemma when students  misbehave or violate class rules. They often turn to some type of punitive retribution that may or may not bring about positive changes in student behavior. Punishment can create as many problems as it solves and may be effective at temporally stopping bad behavior but useless at creating long-term positive changes.


Rewards to increase positive behavior or enhance learning can likewise create serious and unexpected consequences. To believe  that material rewards are necessary for learning is simplistic and incorrect. 

Careless use of rewards by teachers
may discourage charitable behavior.

Most of us are raised on a reward/punishment routine by our parents, so it seems OK to apply the same techniques in class, but there are ethical and behavioral issues with both. Punishments have been briefly discussed above. As for rewards, teachers should know that rewarding expected behavior is equivalent to giving a payoff for doing things that are simply right and should not be rewarded. Charitable behavior, for example, is something we want people to internalize as "a right thing to do." It becomes an ethic, and the "reward" should not be an expectation of a prize, but a good feeling from within.

#3. Poor Evaluation Techniques. No. 1 (above) addresses the issue of grading homework, but there is a large class of student work that need not be graded. They are generally called "formative assessments" and include lots of written classwork (like worksheets) which students complete while they are learning something new. Getting students used to completing work that they know will not  be graded may seem difficult, but the solution lies in convincing them that what they do helps them learn the material for formal testing (summative assessments). That also means that teachers must plan and select class activities that actually do help students learn. 

The big bonus for teachers is that there are fewer papers to grade, since students can correct answers in class. Teachers must help students see the relationship between formative work and summative grades. Parents should be kept up to date about whether or not students are completing formative work-- not because it is graded, but because failure to complete formative assignments can result in lower grades on tests.

Many teachers record 40 or more grades per student per grading period. Some of  these grades are for non-academic work like returning important papers with parental signatures, scores for good behavior, deductions for tardiness, etc. Grades or unfortunately used as bribes, rewards, and punishments. Lots of teacher do it, but it is still wrong.

#4. Poor Discipline. Often during class two or three students might continue to talk or be disruptive despite the teacher’s warnings. A common practice is to announce that if unless everyone behaves that the entire class will be punished in some way. This is equivalent to arresting everyone present in a bank even though all of the evidence makes it clear that only one person committed the crime!

Use positive discipline to develop trust  and cooperation.

The intent of this type of negative discipline is to create resentment toward the offender and turn peers against one another. Often the one or two guilty students aren't the most popular kids in school anyway, and punishing the class distances them even more from good role models who typically behave. Holding each member of a class responsible for controlling the behavior of all makes little sense. It is a Machiavellian power approach -- the ends justify the means. If it works, it is deemed "good." 

What these teachers fail to understand is that creating resentment in students is not a good idea. The teacher has made a judgement call that "bad" students deserve to be disliked by peers. Also, students correctly see this technique as unfair and are more inclined to label the teacher as unfair. 

The responsible, well-behaved students in the class may  behave better because they fear the irrational actions of the teacher, not because they respect  the teacher. Those students who cause the problem initially feel great-- they may not like others in class and have found a way to manipulate the teacher. If the resentment created is strong enough, the offending student(s) may become targets of physical violence if the mistreated students decide to take retribution.

#5. Too many Notes. Notes are a pat of the learning process, especially as students get older. But teachers who depend on notes and lectures daily are making a big mistake. Some teachers learn that giving notes can help bring quiet to a noisy class by giving them something to do. I.e., students who are busy writing are not as likely to get involved in misbehavior. 

This does not mean that the students who are busily copying notes are involved in a learning activity. It means that they have something to do. It's like "doodling," and compliance in note-taking helps defeat the boredom of sitting quietly and paying attention. There is no guarantee that students will use notes to study. Indeed, they may never look at them again.

Before using notes teachers should offer tips to students about taking and using notes.

• Listen to what is said by the teacher. Be confident about listening skills.
• Writing word for word is not necessary. Key words and concepts can be studied later.
• Abbreviate liberally. Develop unique shorthand symbols.
• Don’t copy what is already known well.
• Ask questions for clarification.
• Students should organize notes in a way that they understand.
• Use highlighters to emphasize key points.
• Have a designated notebook for notes. No loose-leaf paper that ends up stuffed into a book bag.
• Review notes soon after taking them. Compare them with classmates.

There are many ways for students to take notes. Teachers should not dictate a precise method. The important thing is that the notes are meaningful and useful to the student. 

Notes have their place, but teachers who use them as the main instructional method on a daily basis run the risk of being boring and ineffective.

#6. Failure to Know and Treat Students as Individuals. One size does not fit all. Cookie-cutter teaching does not reach everyone. The expectation that all students will react identically to one method of teaching is flawed. 

Teachers need to know something of significance about each students. They need to know something of their families, their hobbies, their reading and math abilities. This does not mean  we delve into their personal lives for sordid details, but the social  grapevine in schools is fruitful and paying attention to it can provide insights into behavior and academic progress. 

Differentiate instruction when possible. With cooperative work, mix the groups frequently rather than allow the same students to work together all the time. 

If students are failing assessments due to particular deficits in basic skills, make tests that are fair to a broad group of students. Be sure vocabulary is appropriate and sentence structure is appropriate for the entire class. 

Talk with parents to gain understanding of students. No need to pry, but parents are usually anxious to share issues that might become barriers. 

Take time to engage each student in polite conversation as time allows. Make each one feel welcome and noticed. Validate their existence as persons of worth. You may be the only person to do so.
