07 18-13 webinar - sharnell jackson - using data to personalize learningDreamBox Learning
Learning and competency data can be useful tools in assessing a student’s individual learning needs. In this month’s Blended Learning webinar, presenters Sharnell Jackson and Tim Hudson shared best practices for organizing and using student data in order to better meet student needs. They also discussed processes for using and analyzing data at the student, classroom, and district levels.
What is the important data that is not being recorded in comparative internat...Frederic Fovet
There have been giant steps made in the last decade with regards to the ways data on student performance is collected, analyzed and used for school improvement (Breakspear, 2014; Rozgonjuk et al., 2019; Wu et al., 2020). Much of the impact of the analysis of this data lies in the fact that it has allowed for large international comparative studies that yield important conclusions on the effectiveness of teaching practices, curriculum, and modes of assessment (Dickinson, 2019; OECD 2000-2015). The PISA framework and annual PISA results have in particular allowed for revealing reflections, at international level, in relation to the objectives, ethos and performance of national educational structures (Krieg, 2019; Patrinos & Angrist, 2018).
International comparative studies carried out on the data collected for the purpose of these large surveys, however, have yet to examine learner diversity or educational system’s ability to develop, grow and sustain inclusive practices in schools (Krammer et al., 2021). As a result, a significant gap exists in the quantitative data that is emerging from international comparative studies (Ainscow, 2015; Booth & Ainscow, 2002; Poulsen & Hewson, 2014).
This presentation will (i) examine the limitations of international, comparative standardized data on the issues of learner diversity and inclusive practices, (ii) explore the quantitative tools that do exist but are currently under-utilized in terms of data mining, (iii) examine the challenges and opportunities which lie ahead in relation to the development of sustainable quantitative tools that might allow for comparative analysis of the various ways national education systems tackle the task of differentiating education.
ANALYSIS OF EDUCATIONAL EXPENDITURES NEEDS AND RESOURCES.pptxDrHafizKosar
OBJECTIVE
This assignment aims to analyses an understanding relationship between the needs and resources of educational expenditures and their application in educational setting.
EDUCATIONAL EXPENDITURES:
Education expenditures encompass the financial resources allocated to educational institutions for various purposes, including teacher salaries, infrastructure development, instructional materials, and administrative costs (World Bank, 2007).
EDUCATIONAL NEEDS:
Educational needs vary across contexts and may include improvements in infrastructure, access to quality teaching materials, teacher training, and support services for diverse learners (UNESCO, 2015).
EDUCATIONAL RESOURCES:
Resources in education encompass not only financial assets but also human resources, technology, and community support. Effective utilization of these resources is crucial for achieving educational goals (Hanushek & Luque, 2003).
BALANCING EXPENDITURES AND NEEDS:
Striking a balance between educational expenditures and identified needs is essential for optimizing the impact of financial investments in education (Bruns, Mingat, & Rakotomalala, 2003).RESOURCE ALLOCATION STRATEGIES:
Various strategies for efficient resource allocation in education involve evidence-based decision-making, needs assessments, and prioritizing investments in areas that will yield the greatest educational impact (Hanushek et al., 2013).
WHAT IS ANALYSIS OF EDUCATIONAL EXPENDITURES
Analyzing educational expenditures involves assessing the financial aspects of educational systems, considering both needs and available resources. Needs Assessment:
• Identifying the educational requirements of a given population.
• Examining factors such as student enrollment, infrastructure, curriculum development, and teacher training.
• Understanding the specific needs of diverse learners and ensuring inclusivity.
Resource Evaluation:
• Assessing the financial resources allocated to education, including government funding, private contributions, and grants.
• Analyzing the efficiency of resource utilization to meet educational goals.
• Evaluating the adequacy of funding for various educational components.
Cost-Benefit Analysis:
• Evaluating the effectiveness of educational expenditures in terms of outcomes achieved.
• Assessing the long-term benefits of investments in education, such as improved workforce skills and societal development.
Monitoring and Adjustments:
• Establishing mechanisms for ongoing monitoring and evaluation of expenditures.
• Making adjustments based on changing educational needs, economic conditions, and emerging trends.
Stakeholder Involvement:
• Involving various stakeholders, including educators, parents, and community members, in the decision-making process related to educational expenditures.
• Encouraging transparency and accountability in the management of educational finances.
Education policies play a crucial role in creating the future of the evolving education sector. Education policy jobs include a broad range of roles. It includes making laws to implementing programs that directly impact students, teachers, and others.
Talk by Rebeca Ferguson (Open University, UK, and LACE project).
The promise of learning analytics is that they will enable us to understand and optimize learning and the environments in which it takes place. The intention is to develop models, algorithms, and processes that can be widely used. In order to do this, we need to move from small-scale research within our disciplines towards large-scale implementation across our institutions. This is a tough challenge, because educational institutions are stable systems, resistant to change. To avoid failure and maximize success, implementation of learning analytics at scale requires careful consideration of the entire ‘TEL technology complex’. This complex includes the different groups of people involved, the educational beliefs and practices of those groups, the technologies they use, and the specific environments within which they operate. Providing reliable and trustworthy analytics is just one part of implementing analytics at scale. It is also important to develop a clear strategic vision, assess institutional culture critically, identify potential barriers to adoption, develop approaches that can overcome these, and put in place appropriate forms of support, training, and community building. In her keynote, Rebecca introduced tools, resources, organisations and case studies that can be used to support the deployment of learning analytics at scale

What does the future hold for learning analytics? In terms of Europe’s priorities for learning and training, they will need to support relevant and high-quality knowledge, skills and competences developed throughout lifelong learning. More specifically, they should improve the quality and efficiency of education and training, enhance creativity and innovation, and focus on learning outcomes in areas such as employability, active-citizenship and well-being. This is a tall order and, in order to achieve it, we need to consider how our work fits into the larger picture. Drawing on the outcomes of two recent European studies, Rebecca will discuss how we can avoid potential pitfalls and develop an action plan that will drive the development of analytics that enhance both learning and teaching.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Data Description
35
36. MEASURES OF CENTRAL TENDENCY
• A value that represents a typical, or central, entry of a data set.
• Most common measures of central tendency:
• Mean
• Median
• Mode
36
37. MEASURE OF CENTRAL TENDENCY: MEAN
• Is the sum of all the data entries divided by the number of entries.
• Population mean:
• Sample mean:

37
38. MEASURE OF CENTRAL TENDENCY: MEDIAN
• The value that lies in the middle of the data when the data set is arranged in
order from lowest to highest.
• Measures the center of an ordered data set by dividing it into two equal parts.
• If the data set has an
• odd number of entries: median is the middle data entry.
• even number of entries: median is the mean of the two middle data entries.
- The position of the median can be find using the following formula:
• Position of the median = (n+1)/2 , where n is the sample size.
38
39. COMPUTING THE MEDIAN
If the data set has an:
• odd number of entries: median is the middle data entry:
• even number of entries: median is the mean of the two middle data entries:
39
2 5 6 11 13
median is the exact middle value:
median is the mean of the by two numbers:
2 5 6 7 11 13
Median = 6

40. Median for grouped data
- The median for grouped data can be calculated using the
following formula.
Where,
Lm = lower limit of the class containing the median.
wm = width of the class in which the median lies.
fm = frequency in the class containing the median.
n = total number of frequencies.
fm = cumulative number of frequencies in all the classes
immediately preceding the class containing the median.
** To identify the class of median, we need to find the middle
observation which is determined by n/2.

41. MEASURE OF CENTRAL TENDENCY: MODE
• The data entry that occurs with the greatest frequency.
• If no entry is repeated the data set has no mode.
• If two entries occur with the same greatest frequency, each
entry is a mode (bimodal).
• Examples:
1) 5.40 1.10 0.42 0.73 0.48 1.10
2) 27 27 27 55 55 55 88 88 99
3) 1 2 3 6 7 8 9 10
Mode is 1.10

42. CATEGORIES OF MODE
No mode Unimodal Bimodal Multimodal
Data set which
each value
occurring once
Data set with one
value that occurs
with highest
frequency
Data set with two
values that occur
with same highest
frequency (2
modes)
More than two
values in a data set
occur with the
same highest
frequency (>2
modes)

43. DISTRIBUTION SHAPES
• The three most important shapes are positively skewed,
symmetric, and negatively skewed.
43
44. MEASURES OFVARIATION (“SPREAD”)
Another important characteristic of quantitative data is how
much the data varies or is spread out.
The 3 most common method of measuring spread are:
1. Range
2. Standard deviation
3. Variance
44
45. RANGE
• The difference between the maximum and minimum data
entries in the set.
• The data must be quantitative.
• Range = (Max. data entry) – (Min. data entry)
45
46. STANDARD DEVIATION ANDVARIANCE
• The standard deviation is the most used measure of dispersion.
• The value of the standard deviation tells how closely the values of a data set
are clustered around the mean.

48. ❖In general, a lower value of the standard deviation for a
data set indicates that the values of that data set are
spread over a relatively smaller range around the mean.
❖In contrast, a large value of the standard deviation for a
data set indicates that the values of that data set are
spread over a relatively large range around the mean.

49. POPULAR STATISTICAL METHOD USED
IN DEVELOPMENT RESEARCH
• One sample t-test
• Paired sample t-test
• Correlation
49
51. ONE SAMPLE T-TEST
• to determine whether an unknown population mean is different from a specific value.
• Assumptions:
i. The data are numeric
ii. Independent (values are not related to one another)
iii. Continuous
iv. the population is assumed to be normally distributed.
51
52. EXAMPLE
The average score in the statistics test at a
university has been 28 points for years. This
semester a new online statistics tutorial was
introduced. Now the course management
would like to know whether the success of the
studies has changed since the introduction of
the statistics tutorial: Does the online statistics
tutorial have a positive effect on exam results?

53. INDEPENDENT SAMPLE T-TEST
• to test the difference between means when the two samples are independent and when
the samples are taken from two normally or approximately normally distributed
populations.
• Assumptions:
i. The data are numeric
ii. Observations are independent of one another (that is, the sample is a simple
random sample and each individual within the population has an equal chance of
being selected)
iii. The sample mean, is normally distributed
iv. Equal variances between groups.

53
54. PAIRED SAMPLE T-TEST
• observations in the first sample are directly related to the observations in the second
sample or they occur as pairs of values.
• Assumptions:
• The dependent variable must be continuous (interval/ratio).
• The observations are independent of one another.
• The dependent variable should be approximately normally distributed.
• The dependent variable should not contain any outliers.
54
55. • Examples of dependent samples:
a) To determine students’ achievement using a new teaching method by
having pre-test and post-test.
b) To investigate the effectiveness of a games on the topic straight-line
for secondary school students.
c) To investigate the students’ interest on different subjects.

56. EXAMPLE
• A physical education director claims by taking a special vitamin, a weightlifter can increase
his strength. Eight athletes are selected and given a test of strength, using the standard
bench press. After 2 weeks of regular training, supplemented with the vitamin, they are
tested again. Test the effectiveness of the vitamin regimen at α=0.05. Each value in these
data represents the maximum number of pounds the athlete can bench-press. Assume
that the variable is approximately normally distributed.
Athlete 1 2 3 4 5 6 7 8
Before (X1) 210 230 182 205 262 253 219 216
After (X2) 219 236 179 204 270 250 222 216

57. CORRELATION
• Correlation is a statistical method used to determine whether a relationship between variables
exists.
• Correlation coefficient is a measure to determine whether two or more variables are related and
also to determine the strength of the relationship.
• There are 2 types of relationship: simple or multiple.
• Simple relationship -- there are only two variables under study
• Multiple relationship -- several variables are under study
• Simple relationships can be either positive or negative.
• A positive relationship exists when both variables increase or decrease at the same time. In a
negative relationship, as one variable increases, the other variable decreases, and vice versa.
57
58. CORRELATION COEFFICIENT
• The correlation coefficient computed from the sample data measures the
strength and direction of a relationship between two variables.
• The symbol for the sample correlation coefficient is r while the symbol
for the population correlation coefficient is ρ.
58
59. • The range of the correlation coefficient is from -1 to +1 (-1 ≤ r ≤+1). If there is a strong
positive linear relationship between variables, the value of r will be close to +1. If there is
a strong negative linear relationship between the variables, the value of r will be close to
-1.Where there is no linear relationship or only a weak relationship, the value of r will be
close to 0.
• The formula for the correlation coefficient, r is given below:
