A Strategic Approach: GenAI in EducationPeter 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.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

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.

Assistant Professor & HOD
Department of Agronomy
School of Agricultural Sciences
Career Point University, Kota (Raj.)
3. Career Point Cares
Agronomy is a branch of agricultural sciences which deals with
principles and practices of soil, water and crop management.
This term is derived from Greek words agros meaning ‘ field’ and
nomos meaning ‘ to manage ‘.
4. Career Point Cares
The term agriculture is derived from the Latin words ‘ ager or agri
meaning ‘soil’ and culture meaning ‘ cultivation’.
Agriculture is a very broad term encompassing all aspects of crop
production, livestock farming, fisheries, forestry etc.
5. Career Point Cares
Scope of Agronomy
1. Yield maximization with introduction of new cultivars.
2. Reduced cost of production due to proper crop management.
3. Better water use efficiency due to agronomic knowledge.
4. Special tillage and intercultural operations for better crop growth

Seed and Sowing
Seed: Seed is a fertilized matured ovule together covered with seed coat is
called seed or it is a propagating material.
Type of seed:
1. Monocots
2. Dicots
9. Career Point Cares
MONOCOTS DICOTS
Embryo with single cotyledon Embryo with two cotyledons
Germination usually hypogeal (Except in onion) Germination usually epigeal (except in pea, gram)
Flower parts in multiples of three Flower parts in multiples of four or five
Major leaf veins parallel Major leaf veins reticulated
Stem vacular bundles scattered Stem vascular bundles in a ring
Secondary growth absent Secondary growth often present
Grains, (wheat, corn, rice, millet) sugarcane, banana,
ginger, onions, grass
Legumes (pea, beans, lentils, peanuts) ,tomato, tree, etc
10. Career Point Cares
1.Epigeal Germination : The cotyledons come out above the soil surface and
generally turn green and act as first foliage leaves. This type of germination
present in groundnut, bean, cotton, sunflower and cotton seeds.
11. Career Point Cares
2.Hypogeal Germination The cotyledons do not come above the soil
surface. This type of germination is found in wheat, barley, maize and
pea.
12. Career Point Cares
Methods of Sowing: The sowing method is determined by the crop to be
sown. There are 6 sowing methods which differ in their merits, demerits
and adoption. Those are:
1. Broad casting
2. Drilling or Line sowing
3. Dibbling
4. Transplanting
5. Planting
6. Putting seeds behind the plough
13. Career Point Cares
1. Broad casting: It is the scattering of seeds by hand all over the prepared
field followed by covering with wooden plank for contact of seed with
soil. Crops like wheat, paddy, Sesamum, methi, coriander, etc. are sown
by this method.
2. Drilling or Line sowing: It is the dropping of seeds into the soil with
the help of implement such as seed drill and then the seeds are covered
by wooden plank to have contact between seed & soil. Crops like Jowar,
wheat Bajara, etc. are sown by this method.
14. Career Point Cares
3. Dibbling: It is the placing or dibbling of seeds at cross marks (+) made in the
field with the help of maker as per the requirement of the crop in both the
directions. It is done manually by dibbler. This method is followed in crops like
Groundnut, Castor, Cotton, etc. which are having bold size and high value.
4. Transplanting: It is the raising of seedlings on nursery beds and transplanting
of seedlings in the laid out field. For this, seedlings are allowed to grow on
nursery beds for about 3-5 weeks. Beds are watered one day before the
transplanting of nursery to prevent jerk to the roots. The field is irrigated before
actual transplanting to get the seedlings established early & quickly which
reduce the mortality. This method is followed in crops like paddy, fruit,
vegetable, crops, tobacco, etc.
15. Career Point Cares
5. Planting: It is the placing of vegetative part of crops which are
vegetative propagated in the laid out field. E.g.: Tubers of Potato,
mother sets of ginger & turmeric, cuttings of sweet potato &
grapes, sets of sugarcane.
6. Putting seeds behind the plough: It is dropping of seeds behind
the plough in the furrow with the help of manual labour by hand.
The seeds are covered by successive furrow opened by the plough.
This method is not commonly followed for sowing of the crops.
16. Career Point Cares
Tillage and Tilth
Tillage : Tillage is the physical manipulation of soil with tools and
implements to result in good tilth for better germination and subsequent
growth of crops.
Why tillage is important: Reduced tillage systems may have more
weed, insect, and disease problems than conventional systems. More
residue cover can increase overwintering survival of some insects
and diseases and delay crop development due to cool, wet soils,
increasing the risk of infestation.
Tilth: Tilth is a physical condition of the soil resulting from tillage.
17. Career Point Cares
Conservation tillage: Conservation tillage is any method of soil
cultivation that leaves the previous year's crop residue (such as corn
stalks or wheat stubble) on fields before and after planting the next crop
to reduce soil erosion and runoff, as well as other benefits such as carbon
sequestration (MDA, 2011).
Minimum tillage: Minimum tillage is a soil conservation system like Strip-
till with the goal of minimum soil manipulation necessary for a
successful crop production. It is a tillage method that does not turn the
soil over. It is contrary to intensive tillage, which changes the soil
structure using ploughs.
18. Career Point Cares
Zero tillage: No-till farming (also called zero tillage or direct drilling) is a
way of growing crops or pasture from year to year without disturbing the
soil through tillage.
19. Career Point Cares
Crop density and geometry
Crop density : Density in plant ecology is defined as the number of
individuals of a given species that occurs within a given sample unit or
study area. Density is often used in a vegetation survey to describe a
species' status in a plant community.
Crop geometry : Crop geometry refers to the shape of the space available
for individual plants. It influences crop yield through its influence on
light interception, rooting pattern and moisture extraction pattern. Crop
geometry is altered by changing inter and intra-row spacing (Planting
pattern).
20. Career Point Cares
Crop Nutrition :Proper nutrition is essential for satisfactory crop growth and
production. The use of soil tests can help to determine the status of plant
available nutrients to develop fertilizer recommendations to achieve
optimum crop production. There are at least 17 elements known to be essential
for plant growth.
Essential Elements: Plants need 17 elements for their growth and completion of
life cycle. they are: carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium,
calcium, magnesium, sulphur, iron, manganese, zinc, copper, boron,
molybdenum and chlorine, nickel. In addition, four more elements sodium,
cobalt, vanadium and silicon are absorbed by some plants for special purposes.
21. Career Point Cares
The elements C, H, O are not minerals. The rest of the elements are
absorbed from the soil and these are called mineral elements since they
are derived from minerals. These mineral elements are mainly absorbed
in ionic form and to some extent in non-ionic form.

Manures and Fertilizers
Plant requires food/nutrients/elements for its growth and development which are
absorbed through soil. The nutrient supplying sources are manures and
fertilizers. Application of manures and fertilizers to the soil is one of the
important factors which help in increasing the crop yield and to maintain the soil
fertility. N, P and K are the 3 major elements required for the crop growth.
Manure: It is a well decomposed refuse from the stable and barn yards including
both animal excreta and straw or other litter.
Fertilizers: These are industrially manufactured chemicals containing plant
nutrients.
