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.

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.

4
5. Shenzhen KYL Communication Equipment Co., Ltd
1. Power supply
The factory default setting is +5V (needing 3.3-3.6V, please notify us when placing
the order). Using better ripple factor, KYL-200U transceivers can also share power
supply with other equipments. If possible, a voltage-stabilizing chip with 5V
voltage is much recommended than Switch power supply. But if only switch power
supply is available, the jam caused by switch pulse should be avoided. In addition,
the reliable grounding must be used if there is other device in the system equipment.
In case of failing to connect with the ground, it can form its own grounding but
must be absolutely separated from the municipal electric supply.
2. Connection Definition with terminal
KYL-200U transceivers supply one 9-pin connector (JP1), their definitions and
connection methods with terminals are shown in Table 1.

4. Setting of channel, interface, and data format
Before using KYL-200U, the user needs to make simple configuration to
determine the channel, interface mode and data format based on his own needs.
You can view or change the module's interface baud rate, channel and address
code, parameter setting or reading as per the testing software KYLCOM in the PC
(in products box). And the configuration is as follows:
i. Channel configuration:
Channel No. Frequency Channel No. Frequency
1 429.0325MHZ 5 433.0325MHZ
2 430.0325MHZ 6 434.0325MHZ
3 431.0325MHZ 7 435.0325MHZ
4 432.0325MHZ 8 436.0325MHZ
Note: the frequency points corresponding to each channel can be adjusted
based on the user’s needs.
ii. The schematic diagram of setting the parameter is in the following:
a. Connect the PC and module with RS232 data cable.
b. Open the “KYLCOM” PC software, then select “English”:

5. Installation dimension:
6. The Function-indicator light
a. The LED indicator light will turn red for 0.5S once switch on.
b. The LED indicator light will turn green continually while receiving data from
air.
c. The LED indicator light will turn red continually when transmitting data into air
after receiving from COM.
d. If the module keeps sleep function, LED indicator light is always dark.
7. Supported protocol and Transmit capability
KYL-200U standard transceivers offer transparent protocol to support various
applications and protocols of users. If the user needs to decrease his cost or ease the
workload of terminal CPU, we can add other specific functions based on the
transparent protocol, such as addressing, data acquisition, command interpretation,
etc.
8. Sleep function instruction:
In order to reduce consumption, KYL-200U transceivers support Sleep function. In
sleep mode, the current consumption is less than 20uA.
a. How to use the Sleep function:
The Pin8 ‘SLP’ in JP1 is the signal of sleep control. At high power level,
transceiver stays in working mode. At low power level (<0.5V), transceiver stays
in sleep mode. The SLP signal can convert transceiver from working to sleep
mode in 1ms after falling edge. If the Sleep signal arrives when the transceiver is
transmitting data, the module will move to sleep mode after finishing
transmission. From sleep mode to working, it takes the transceiver 1ms after
rising edge.
To disable the opened sleep function of KYL-200U, the SLP (SLEEP) pin
should be definitely connected with 0 or ground.
10
11. Shenzhen KYL Communication Equipment Co., Ltd
b. Attentions about use of sleep function:
When the sleep function enabled, or any supply glitches, such as switch dithering,
fire striking or quick switching on and off, may cause the transceiver switch to
wrong sleep mode.
After switching on, users can avoid this error by making a compulsive
restoration once after the CPU delays 100ms.
Sleep Timing Diagram:
9. Attentions in data transmission
a. The delay time (tc) of conversion between transmitting and receiving is less
than 1ms.
Timing diagram:
b. The delay time of transceivers between the first bit sent by TxD to the first
bit received by RxD.
As data processing will be made on user’s data by KYL-200U transceiver using
FEC (Forward Error Correction) or other correction algorithm, when RxD of a
KYL-200L transceiver ‘A’ receives the data, then transmits it, the other one
transceiver ‘B’ will have a delay (ts) to receive and transmit by TxD. Different
RF data rate causes different delay time. Please see the specific delay time
below:
11
12. Shenzhen KYL Communication Equipment Co., Ltd
RF Date Rate Delay RF Date Rate Delay
(bps) Ts(mS) (bps) Ts(mS)
1200 90 9600 16
2400 48 19200 10
4800 30
Timing diagram:
c. Error dealing procedure:
To enhance the reliability and stability of user’s systems, a verify bit or a Cyclic
Redundancy Check (CRC) mode is highly recommended to prevent wrong
information while using KYL-200L modules.
d. Large-number data transmission
In theory, when the interface data rate is faster than the RF data rate, KYL-200U
transceivers can sent unlimited-long data package, but long packages more than
120B are not recommended. The length of each package should be between
60~100B. We also recommend our users to use Automatic Error Request
Equipment (ARQ) to prevent wrong information.
Reasons:
What if the actual transmission BER (Bit Error Rate) is 10-4, 1 packet with 1KB
data which is about 10-thousand bits, is sent, theoretically, at least 1 bit will be
received wrongly, then the 1KB information will never be received correctly.
But if we package the data into 10 packets with 100B for each, when all 10
packets are sent, there will be only 1 packet wrong according to this probability.
After that, resend this wrong packet using ARQ mode. So by resending one more
packet and the efficiency rate is reduced 10%, all data will be absolutely received
correctly.
10. Antenna configuration:
Many appropriative antennas for low power RF modules are selected to meet
different users’ antenna configurations. Please ask our Sales for more information
about the antenna’s dimension and performance.

If the user has special demands on antennas, we can design and produce for them
specially.
V. Network Application of KYL-200U
The communication channel of KYL-200U is half duplex, which is most suitable
for the communication mode of point to multi-point. Under this mode, one
master station must be set, and all of the rest are slave stations. A unique address
13
14. Shenzhen KYL Communication Equipment Co., Ltd
is given to each station. The coordination of communication is controlled by
master station that uses data frames containing address code to transmit data or
command. Slave station will receive all of the data and command and compare
the received address code with local address code. If they are different, the data
will be deserted without any response. If those address codes are the same, it
means the data is sent to the local. Slave station will make different responses
according to the transmitted data or command and send back the data of response.
All these jobs must be performed by upper protocol, and it is assured that there is
only one transmitter-receiver in the state of transmission in the communication
network at any instant moment so as to avoid the cross-interference.
KYL-200U can also be used for point-to-point communication with easier
operation. For the programming of serial port, all you have to do is to remember
that its communication mode is semi duplex while always observing the time
sequence of come-and-go for receiving and transmitting.
