Motivation
It's not too uncommon to associate motivation to catch-phrases, celebrity spokespeople, and miracle stories. Long term motivation for students is a bit more subtle, but can be broken down into three main influences. Let's familiarize ourselves with them.
A student's surroundings will undoubtedly have a significant influence on behavior and motivation. Static elements (environmental cues) and peers (social cues) each are given a dedicated section elsewhere on this site due to their enormous influence. Here are two studies which should give you a basic understanding of the power of environmental and social cues on motivation:
From 2004 to 2006, Stephen B. Plank and colleagues from Johns Hopkins University conducted a correlational study to determine the degree to which the physical appearance of the school and classroom setting influence student behavior, particularly in respect to the variables concerned in their study: fear, social disorder, and collective efficacy. They collected survey data administered to 6th-8th students by 33 public schools in a large mid-Atlantic city. From analyses of the survey data, the researchers determined that the variables in their study are statistically significant to the physical conditions of the school and classroom setting.
...the findings of the current study suggest that educators and researchers should be vigilant about factors that influence student perceptions of climate and safety. Fixing broken windows and attending to the physical appearance of a school cannot alone guarantee productive teaching and learning, but ignoring them likely greatly increases the chances of a troubling downward spiral.
A report from Caroline Hoxby suggest that having a more female peer group raises both male and female scores in reading and math. To identify true peer effects, Hoxby compares groups within a given school that differ randomly in peer composition. She controls other common variables, such as home environment and student achievement. One of her results suggested that having a more female peer group raises both male and female scores in reading and math. She points out that only some of the "good" peer effect of females can be direct learning spillovers because females do not know math better than males on average, although they are better readers. The fact that females raise math scores, therefore, must be due to phenomena more general than direct learning spillovers -- for instance, females' lower tendency to disrupt.
Small differences can accumulate and undergo exponential change over the course of many years. Studies like the ones suggest cryptic influences on behavior. For example, a poorly maintained class may be detrimental to motivation. Having male tablemates may result in dramatically different scores in math than having female tablemates. Many of these variables are beyond our control, but we should be aware of their influence.
The book How Learning Works describes these three factors in detail. The three levers (value, efficacy expectancies, and the environment) can influence motivation. Neglect of any one of the three can substantially influence motivation. Below are general cases that occur under different circumstances.
The environment has a significant influence on motivation. Classroom atmosphere impacts day to day behavior.
Carefully choose classes based on class environment in addition to academic goals. Obtain information from past students if possible.
The place where you situate yourself in a classroom may impact learning.
Choose seating to avoid distractions and problem students. Put yourself in the front of the class.
Your perceptions about your abilities influence behavior. The perception of control can help sustain motivation.
Avoid focusing on things that are beyond control such as having a bad teacher or not being a "math person". Shift your thoughts to things you can control. After doing poorly, think about the factors you control. "I'll put more work in next time."
Be cautious of extrinsic rewards and punishments.
Threats and rewards are short term solutions. In the long term, they do more harm than good.
