This invention relates to the field of teaching and more particularly to a system and method for measuring the efficiency and the effectiveness of the educational process and systems.
Teaching is a skill and an art. Being such, it is often difficult to measure the quality of education that has occurred. Teachers, professors, instructors and the like have varying attributes such as education, subject matter knowledge, personalities, styles, emotions, drive, speech patterns, etc. In addition, teachers contend with classes of varying size that affect their ability to interact with students in the classroom, and in any help sessions. Likewise, their students also have varying attributes such as prior education, personalities, styles, emotions, drive, attention patterns, study skills, etc. It is often hard to measure, let alone predict the outcome of a learning experience involving a subject, a teacher, a set of students and a time frame because of the complex interactions among this myriad of attributes.
Often, teachers are rated, and perhaps paid, based upon years in teaching. Although there may be some correlation between years in teaching, teaching ability and teaching effectiveness, there is no absolute direct relationship and, therefore, this evaluation method falls short.
In recent times, standardized tests have been used to measure the level a group of students have achieved on specific subjects or a broad range of knowledge. Many of these tests have been deployed to help colleges and institutions evaluate new student prospects, for example, the SAT and GRE exams. Most, if not all states, such as California, Florida, Ohio and New York, have standardized tests for evaluating the overall achievement of a group of students such as an entire grade level within a particular school. Such tests are used to evaluate the school and the overall school's ability to teach. Although still in use at the time of filing, this system has inaccuracies due to student demographics, teacher attributes, public pressure, etc., but especially because of several features of the present invention that are missing from such evaluations.
The prior art has several examples of methods for measuring teaching success. For example, US Patent Publication 20050297505 to George describes a method of teaching success. This method may help students generate and achieve goals, but it does not measure the efficiency or effectiveness of the teacher or of the educational system.
US Patent Publication 20040157201 to Hollingsworth, et al., describes a method for evaluating educational effectiveness. This method uses “time on task” and “instructional effectiveness” to evaluate educational effectiveness, but does not measure overall efficiency and effectiveness of the educator, nor the process employed by the educational system.
U.S. Pat. No. 6,789,047 to Woodson describes a method for evaluating an instructor using data captured during an electronic course (online) such as attendance and response time to questions. It does not measure before and after results and time spent.
What is needed is a system and method that will measure the efficiency and effectiveness of the educational system at several levels so that potential improvements can be identified and implemented.
In one embodiment, a system for measuring efficiency of educational activities is disclosed including a computer with software running on the computer that accepts inputs indicating an amount of effort expended and accumulating these inputs into an accumulated effort. Software is provided that accepts inputs indicating an educational goal such as credit-hours gained (or course hours of content completed), a knowledge level of a group of students before the teaching activities are performed, and inputs indicating a knowledge level of the group of students after the teaching activities are performed. Software is also provided for calculating the educational efficiency as a difference between the knowledge level of the group of students before the educational activities and the knowledge level of the group of students after the educational activities times the credit hours or the course hours and divided by the accumulated effort.
In another embodiment, a method for measuring educational efficiency and effectiveness of an educator and a group of students toward an educational goal is disclosed including measuring both the amounts of effort expended during educational activities and the costs of teaching (e.g. teacher wages and classroom and laboratory supply costs) into an accumulated cost. The knowledge level of the group of students is measured before the teaching activities and after the teaching activities. The educational efficiency is calculated as a difference between the knowledge level of the group of students before the teaching activities and the knowledge level of the group of students after the teaching activities times the number of credit hours (or course hours) divided by the accumulated effort for the group. The educational effectiveness is calculated as the difference between the knowledge level of the group of students before the teaching activities and the knowledge level of the group of students after the teaching activities times either the number of credit hours or the course hours and that product divided by the accumulated cost for the group.
In another embodiment, a computer storage medium tangibly embodying a program of instructions, the program of instructions produces a teaching efficiency and effectiveness of an educational system employed for teaching a varying sized group of students. The program includes computer instructions that measure amounts of effort and cost expended during teaching activities and computer instructions that accumulate the amounts of effort and cost into an accumulated effort and accumulated expenses associated with providing the educational experience. Computer instructions are provided that accept the knowledge level of the group of students before the teaching activities and the knowledge level of the group of students after the teaching activities. Furthermore, computer instructions are provided that calculate the educational efficiency and effectiveness as a the difference between the knowledge level of the group of students before the teaching activities and the knowledge level of the group of students after the teaching activities times the credit hours of the course (or course hours) divided by the accumulated effort or costs, respectively.
The invention can be best understood by those having ordinary skill in the art by reference to the following detailed description when considered in conjunction with the accompanying drawings in which:
Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in all figures. Throughout the description, the term “course hours” represents a measurement of time spent and, in some examples, the same as “credit-hours.” Course hours is any measurement of time and the present invention produces meaningful results as long as each measurement includes the same definition of course hours.

In general, the hard disk 140 is often used to store programs, executable code and data persistently, while the CDROM 150 is often used to load such programs, executable code and data from removable media onto the hard disk 140. These peripherals are meant to be examples of input/output devices, persistent storage and removable media storage. Other examples of persistent storage include core memory, FRAM, flash memory, etc. Other examples of removable media storage include CDRW, DVD, BlueRay, DVD writeable, compact flash, other removable flash media, floppy disk, ZIP®, laser disk, etc. In some embodiments, other devices are connected to the system through the system bus 120 or with other input-output connections. Examples of these devices include printers; mice; graphics tablets; joysticks; and communications adapters such as modems and Ethernet adapters.

Next, teaching proceeds 14 and during such, the amount of effort and cost is accumulated 15. The amount of effort is a measure of work expended by the students and educator and includes some or all of classroom time, online time, study time, homework time, discussion group time, educator time spent grading, preparation, research, tutoring, etc. Costs are those expenses associated with providing the educational opportunity being evaluated, and for some measures may be partial costs. If the curriculum is not complete 16, the steps of teaching 14 and accumulating effort and costs 15 are repeated until the curriculum is complete 16. Once complete, the students are again tested using a post-test 18. The post-test is, necessarily, similar in scope but preferably not identical to the pre-test and therefore provides a measurement of how much the students learned during the teaching steps. Subtraction of the pre-test results from the post-test results provides a measurement of basic learning. It represents the fraction of the educational goal; for example the course credit hours mastered in the course measured. This measurement of basic learning is just that—how much more the students know now than they knew before the course began. This raw measurement does not take into account either the amount of time expended or the monies expended to achieve this increment of learning. The basic learning (post-test scores minus pre-test scores) multiplied by either credit-hours or course hours as a learning goal is divided by the accumulated effort to provide a measurement of educational efficiency 20. Likewise, the basic learning is divided by the accumulated cost to provide a measurement of educational effectiveness 22.
For example, consider two United States Department of Commerce classes, one of 15 students and another of 8 students, learning the Japanese language. The subject matter is taken in this example as a two (2) college-level credit-hours class. In Japanese 101, one must first learn the Katakana and Hiragana characters used as a phonetic alphabet. Both classes are tested before any teaching occurs to see how many of the Katakana and Hiragana characters are recognized by the students. Referring to
Assuming a teacher salary allocated to this course of $400 per student per credit hour and no other costs, the cost effectiveness 222 is determined by dividing educational accomplishment by the cost to arrive at a value of 3.50 effective credit-hours/$1000.

If methods of the prior art were applied to these scores, it would have looked like the second set of students started with slightly more knowledge and finished with slightly more knowledge than the first group, but nothing would indicate which teacher performed better at teaching and motivating each class. Moreover, much of any difference would be masked by the difference in class size. For the second class, as per the present invention, the measured gain in knowledge (90%-25%) is multiplied by the learning goal of two (2) credit hours and is divided by the work effort of 36 hours to determine the teaching efficiency 320. In this example, teaching efficiency is 2×(0.90-0.25)/36, or 0.036. The effectiveness is calculated as in the previous example. Because of the smaller class size, even though the teacher wage rate is constant, the per student cost increases to $750 per student per credit hour. The effectiveness 322 for the second class thus is 2×(0.90-0.25)*1000/750 giving an effectiveness of 1.73 effective credit-hours per $1000.
Both classes finished knowing roughly the same measured number of Hiragana and Katakana characters and both are adequately prepared to move on to the next level of Japanese learning. By simply comparing the post-test results of the first educator (85%) to the second educator (90%), it would appear that the second class (or perhaps teacher) out performs the first, a result the present invention shows to be incorrect. The present invention provides a method for comparing educators, educational environments, curriculum, teaching methods, etc. Using the teaching efficiency and effectiveness measures shows that the first class's educational experience was superior despite a lower post-test score.
The raw test results might lead one to conclude that the teacher for the second class was substantially inferior. An advantage of the present invention is that a factor such as class size is isolated analytically. Referring to

Next, teaching proceeds 1014 and during such, the amount of effort and cost is accumulated 1015. The amount of effort is a measure of work expended by the students and educator and includes some or all of classroom time, study time, homework time, discussion group time, educator time spent grading, preparation, research, tutoring, etc. Costs are those expenses associated with providing the educational opportunity being evaluated, and for some measures may be partial or allocated costs. If the curriculum is not complete 1016, the steps of teaching 1014 and accumulating effort and costs 15 are repeated until the curriculum is complete 1016. Once complete, the students are again tested using a post-test 1018. The post-test is, necessarily, similar in scope but preferably not identical to the pre-test and therefore provides a measurement of how much the students learned during the teaching steps. Subtraction of the pre-test results from the post-test results provides a measurement of basic learning. It represents the fraction of the educational goal; for example the course credit hours mastered in the course measured. This measurement of basic learning is just that—how much more the students know now than they knew before the course began. This raw measurement does not take into account either the amount of time expended or the monies expended to achieve this increment of learning. The basic learning (post-test scores minus pre-test scores) is multiplied by the credit hours (or effective course hours) to determine a value for effective credit hours (or course hours) 1020. The effective course hours is then divided by the accumulated effort to provide a measurement of educational efficiency 1022. Likewise, the effective credit hours (or course hours) is then divided by the accumulated cost to provide a measurement of educational effectiveness 1024.
For example, consider the above two United States Department of Commerce classes, one of 15 students and another of 8 students, learning the Japanese language. The subject matter is taken in this example as two (2) college-level credit-hours. In Japanese 101, one must first learn the Katakana and Hiragana characters used as a phonetic alphabet. Both classes are tested before any teaching occurs to see how many of the Katakana and Hiragana characters are recognized by the students. Referring to
Assuming a teacher salary allocated to this course of $400 per student per credit hour and no other costs, the cost effectiveness is determined by dividing the effective hours (16.8) time 1000 by the cost ($400) to arrive at a value of 42 effective course hours per $1000 1224.

If methods of the prior art were applied to these scores, it would have looked like the second set of students started with slightly more knowledge and finished with slightly more knowledge than the first group, but nothing would indicate which teacher performed better at teaching and motivating each class. Moreover, much of any difference would be masked by the difference in class size. For the second class, as per the present invention, the measured gain in knowledge (90%-25%) is multiplied by the learning goal of two (24) course hours to provide the effective course hours 1320. On a per-student basis, the effective course hours is divided by the effort of 36 hours to determine the teaching efficiency 1322. In this example, the work effort is 24×(0.90-0.25)=15.6 effective course hours. The educational efficiency is then 15.6/36, which yields an efficiency of approximately 0.43. Because of the smaller class size, even though the teacher wage rate is constant, the per student cost increases to $750 per student. The effectiveness for the second class thus is 15.6 effective course hours*1000/$750 giving an effectiveness of 20.8 effective course hours per $1000.
Both classes finished knowing roughly the same measured number of Hiragana and Katakana characters and both are adequately prepared to move on to the next level of Japanese learning. By simply comparing the post-test results of the first educator (85%) to the second educator (90%), it would appear that the second class (or perhaps teacher) out performed the first, a result the present invention shows to be incorrect. The present invention provides a superior method for purpose of comparing educators, educational environments, curriculum, teaching methods, etc. Using the teaching efficiency and effectiveness measures make it clearer that the first class's educational experience was superior despite a lower post-test score.
The expenses attributable to the educational experience that are measurable in dollars include the cost of educator salaries, resource costs, equipment costs, facility costs, travel expense, training or seminar fees, and other education related expense.
The following are examples of expense measurements at an individual class level:
As an example at the class level, the total class level expense is the total of the classroom teaching expense, the classroom supply expense, the laboratory teaching expense, the laboratory supply expense and the development expense. Therefore, the class level teaching effectiveness according to the present invention is the net classroom instructional improvement divided by the total class level expense.
The following are examples of effort measurements at a grade level reflecting, for example, all classes in one particular grade across a school such as all sophomores in a given high school:
As an example at the grade level, the total grade level expense (effort) is the total of the grade classroom teaching expense, the grade classroom supply expense, the grade laboratory teaching expense, the grade laboratory supply expense and the grade development expense. Therefore, the grade level teaching effectiveness according to the present invention is the total classroom instructional improvement for the grade divided by the total grade level expense.
The following are examples of effort measurements at a school level reflecting, for example, all classes in all grades across a given school such as all grades/classes in a given high school:
As an example at the school level, the total school level expense (effort) is the total of the school classroom teaching expense, the school classroom supply expense, the school laboratory teaching expense, the school laboratory supply expense, the school administrative expense and the school development expense. Therefore, the school level teaching effectiveness according to the present invention is the total school instructional accomplishment for the entire school divided by the total school level expense.
The following are examples of effort measurements at a school system reflecting, for example, all schools in a geographic area such as all public schools in New York City:
As an example at the school system level, the total school system level expense (effort) is the total of the school system teaching expense, the school system supply expense, the school system teaching expense, the school system laboratory supply expense, the school system administrative expense and the school system development expense. Therefore, the school system teaching effectiveness according to the present invention is the total school system instructional improvement for the entire school system divided by the total school system level expense.
Equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result.
It is believed that the system and method of the present invention and many of its attendant advantages will be understood by the foregoing description. It is also believed that it will be apparent that various changes may be made in the form, construction and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages.
