Pearson Product-Moment Correlation

What does this test do?

The Pearson product-moment correlation coefficient (or Pearson correlation coefficient, for short) is a measure of the strength of a linear association between two variables and is denoted by r. Basically, a Pearson product-moment correlation attempts to draw a line of best fit through the data of two variables, and the Pearson correlation coefficient, r, indicates how far away all these data points are to this line of best fit (i.e., how well the data points fit this new model/line of best fit).

What values can the Pearson correlation coefficient take?

The Pearson correlation coefficient, r, can take a range of values from +1 to -1. A value of 0 indicates that there is no association between the two variables. A value greater than 0 indicates a positive association; that is, as the value of one variable increases, so does the value of the other variable. A value less than 0 indicates a negative association; that is, as the value of one variable increases, the value of the other variable decreases. This is shown in the diagram below:

How can we determine the strength of association based on the Pearson correlation coefficient?

The stronger the association of the two variables, the closer the Pearson correlation coefficient, r, will be to either +1 or -1 depending on whether the relationship is positive or negative, respectively. Achieving a value of +1 or -1 means that all your data points are included on the line of best fit – there are no data points that show any variation away from this line. Values for r between +1 and -1 (for example, r = 0.8 or -0.4) indicate that there is variation around the line of best fit. The closer the value of r to 0 the greater the variation around the line of best fit. Different relationships and their correlation coefficients are shown in the diagram below:

 

Stanine Scores

What is a Stanine Score?

A stanine (“standard nine”) score is a way to scale scores on a nine-point scale. It can be used to convert any test score to a single-digit score. Like z-scores and t-scores, stanines are a way to assign a number to a member of a group, relative to all members in that group. However, while z-scores and t-scores can be expressed with decimals like 1.2 or 3.25, stanines are always positive whole numbers from 0 to 9.

Stanines are also similar to normal distributions. You can think of these scores as a bell curve that has been sliced up into 9 pieces. These pieces are numbered 1 through 9, starting at the left hand section. However, where a standard normal distribution has a mean of 0 and a standard deviation of 1, stanines have a mean of 5 and a standard deviation of 2.

What do Stanines mean?

A person with a score of 9 is in the top 4% of the scorers, while a person with a score of 1 is in the bottom 4%. These types of scores allow you to easily tell if a score is below the mean (a score of 5) or above the mean.

How to Convert a Score to a Stanine

Step 1: Rank the scores from lowest to highest.

Step 2: Assign a stanine score to your scores from Step 1:

Stanine score	Percentage of scores
1	Bottom 4%
2	Next bottom 7%
3	Next bottom 12%
4	Next Bottom 17%
5	Middle 20%
6	Next top 17%
7	Next top 12%
8	Next top 7%
9	Top 4%

The mean lies in the middle of the fifth stanine, cutting the center 20% into two parts.

Loss of Information

Stanines are a very simple way of categorizing items into top, middle and bottom percentages. This simplicity means that it’s a very imprecise way to measure anything. Everyone in the same stanine receives the same score. For example, a person at the bottom of the 5th is almost 20 percentage points below the person at the top of the 5th. These differences are what is called “loss of information.”

ICT IN TEACHER PROFESSIONAL DEVELOPMENT

ICT IN TEACHER PROFESSIONAL DEVELOPMENT

Researchers have identified many uses of ICT in relation to TPD that can be grouped in three categories:

• A focus of study that develops teachers’ abilities to use specific ICT tools, such as online platforms
• A delivery system providing teachers with information to improve pedagogy and content mastery,
• A catalyst for new forms of teaching and learning, such as inquiry-based learning, collaborative learning, and other forms of learner-centered pedagogy (infoDev, 2005). 

In other words, professional development in the context of ICT can be placed under three broad headings, namely

• Learning How to use ICT
• Learning through ICT
• Integration of ICT in teaching and teacher learning
• .Learning How to Use ICT
  ICT with its versatile nature has found its application in every activity related to educational practice. Some typical questions you may have to address while learning how to use ICT are as follows:
  • How do I use ICTs? (Technical)
  • What can ICTs help me do? (Functional)
  • How can I use ICT tools with so many students? (Logistical)
  • Will these ICT tools and technologies replace me as a teacher? Will my students lose respect if they think the ICT platforms have repositories of knowledge that I don't have? (Affective)
  • How do I organize my classroom to support the use of ICTs? How can they be used as part of what I already do in the classroom? (Organizational)
  • How can I learn from and with ICTs? (Conceptual)
  • How can ICTs help my students learn in different ways? How can they support the curriculum? How can they support my teaching? How should I teach using ICTs? (Instructional)
  • How do I assess student learning in ICT-based projects? (Evaluation related) 
  Another way to look at learning about ICT use in educational purposes is to see the various applications of ICT in educational setting. Following is a non-exhaustive list giving an indication on various areas of ICT application.
  • Learning ICT use for instructional planning
  • Learning ICT use for facilitating learning
  • Learning ICT use for assessment
  • Learning ICT use for school management
  • Learning ICT use for inclusive classrooms
  • Learning ICT use for strengthening school community relationship
  In all these areas of educational practice, ICT can be meaningfully integrated. But, one must know the ICT in the first place. For example, to develop digital lesson plans, one must learn word processing. In order to develop student record database, one need to learn some database management tools. A teacher needs to learn a spreadsheet application so that data can be organized, processed and analyzed. These are only few examples for what you have already discussed in various earlier units.
  Following figure gives a glimpse of illustrative Free and Open Source Software (FOSS) tools that are available for educational purposes:

Importance of ICT in education

Importance of ICT in education:

Being aware of the significant role of ICT in our life, especially in the educational activities, education authorities should be wise enough in implementing the strategies to empower ICT in supporting the teaching and learning process in the classroom.Nowadays the role ofInformation and Communication Technology (ICT),in the education sector plays an important role, especially in the process of empowering the technology into the educational activities. Education sector can be the most effective sector to anticipate and eliminate the negative impact of ICT. Technology in another side can be the most effective way to increase the students knowledge.

                  The use of ICT in education adds value to teaching and learning, by enhancing the effectiveness of learning. It added a dimension to learning that was not previously available. After the inception of ICT in schools, students foundlearning in a technology enhanced environment more stimulating and engaging than in a traditional classroom environment.

                  ICT plays a catalytic role in enhancing learning in classroom and beyond.

Information and communication technologies are extremely influencing every discipline including Education. It is affecting every aspect of education from teaching-learning to assessment and evaluation. It improves the effectiveness of education. It aids literacy movements. It enhances scope of education by facilitating mobile learning and inclusive education. It facilitates research and scholarly communication. Impact of ICT and its potential for the education field is manifold.A judicious use of ICT technologies together with new functions and roles of education personnel can bring about more efficient and effective teaching learning-process.

The main concern here is to bridge the differences amongst the students, parents and teachers leading to an effective interaction and a transparency between the three. An equal importance should also be given to promote the culture of learning at school and to support schools in sharing experience and information with others.

APPLICATIONS OF NORMAL PROBABILITY CURVE

Applications of Normal Probability Curve

The principles of Normal Probability Curve are applied in the behavioural sciences in many different areas.

·         NPC is used to determine the percentage of cases in a normal distribution within given limits:

The Normal Probability Curve helps us to determine:

i. What percent of cases fall between two scores of a distribution.

ii. What percent of scores lie above a particular score of a distribution.

iii. What percent of scores lie below a particular score of a distribution.

·         NPC is used to determine the value of a score whose percentile rank is given:

By using NPC table we can determine the raw score of the individual if the percentile rank is given.

·         NPC is used to find the limits in a normal distribution which include a given percentage of cases:

When a distribution is normally distributed and what we know about the distribution is Mean and the Standard deviation at that time by using the table area under NPC we can determine the limits which include a given percentage of cases.

·         It is used to compare two distributions in terms of- overlapping:

If scores of two groups on a particular variable are normally distributed. What we know about the group is the mean and standard deviation of both the groups. And we want to know how much the first group over-laps the second group or vice-versa at that time we can determine this by using the table area under NPC.

·         NPC helps us in dividing a group into sub-groups according to certain ability and assigning the grades:

When we want to divide a large group in to certain sub-groups according to some specified ability at that time we use the standard deviation units of a NPC as units of scale.

·         NPC helps to determine the relative difficulty of test items or problems:

When it is known that what percentage of students successfully solved a problem we can determine the difficulty level of the item or problem by using table area under NPC.

·         NPC is useful to normalize a frequency distribution:

In order to normalize a frequency distribution we use Normal Probability Curve. For the process of standardizing a psychological test this process is very much necessary.

·         To test the significance of observations of experiments we use NPC:

In an experiment we test the relationship among variables whether these are due to chance fluctuations or errors of sampling procedure or it is real relationship. This is done with the help of table area under NPC.

·         NPC is used to generalize about population from the sample:

We compute standard error of mean, standard error of standard deviation and other statistics to generalize about the population from which the sample are drawn. For this computation we use the table area under NPC
