Chapter >> Page > standardisation meeting

As discussed in 4.1 – Chapter 4, before TNU oral tests are actually administered, no discussion taking place to reach agreement on how to mark each question/task among the group of assessors is proved to also affect test reliability. It would thus be strongly advisable that the English Section should potentially hold just a short standardisation meeting in order to ensure that enough discussion will take place for all examiners to understand thoroughly the level scale and the procedures for scoring. Of course, at this meeting the level scale (discussed in 5.2.3) and the marking key for each test task (discussed in 5.2.5) are really needed. As such a meeting is possible, it will help to increase test reliability. supportive test taking environment

As mentioned in 4.1 – Chapter 4, most of the speaking tests have taken place in noisy rooms, which surely affects students’ test performance and thus reduces reliability of the tests. Therefore, in order to ensure that a test is reliable, it is crucial to maintain a supportive environment throughout the test. In particular, examiners and administrators should avoid distractions due to temperature, noise, excessive movement, and so on, and provide a comfortable room for those students waiting for their turn. In my opinion, it would be feasible for TNU to maintain such a testing environment. use of test results for teaching evaluation

At TNU, as previously described and analysed, students’ test scores have never been used to either determine the effectiveness of instructional programs or make any improvement in teachers’ teaching methods and materials, which reveals that TNU staff do not exploit test potential and usefulness to improve their teaching as well as their testing. This sub-section hence aims at helping the concerned staff to develop a plan for teaching evaluation based on test scores collected.

In particular, teachers should first keep a list of scores in order to evaluate students’ achievement in general, i.e. to find out whether the instruction has helped students develop this skill. Then they should specify typical problems impeding the majority of students’ performance during test administration in order to find out suitable strategies to promote effective learning, i.e. to modify teaching methods and materials.

With the test scores, as Madsen (1983, p. 5) maintains, teachers might well ask themselves whether their teaching is effective, which is particularly suggested using the following questions:

‘1. Are my lessons on the right levels? Or am I aiming my instruction too low or too high?

2. Am I teaching some skills effectively but others less effectively?

3. What areas do we need more work on? Which points need reviewing?

4. Should I spend more (or less) time on this material with next year’s students?’

And test administration can ‘provide insights into ways that we can improve the evaluation process itself.’

‘1.Were the test instructions clear?

2. Did the test cause unnecessary anxiety or resentment?

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
