Table 4.11: Teachers’ Confidence in Students’ Test Results

As shown in table 4.11, 10 out of 12 respondents do not believe that their marks given on the students’ oral test performance can reveal the students’ actual interactive ability.

Table 4.12 presents responses selected for Question 8, used to elicit the reason(s) why the respondents are not or not very sure of the marks they have given on the students’ oral test performance.

Table 4.12: Teachers’ Lack of Confidence in Students’ Test Results

A remarkable thing shown in Table 4.12 is that those who are not sure of the reliability of students’ test scores all believe that their uncertainty results from the students’ prior preparation for test tasks.

Personal details about the respondents from questions 9 and 10 provide important facts:

  • Half of the respondents have taught English for over 8 years, 5 – over 5 years, and only one – over 11 years.
  • Only one of the subjects has attended a course or a workshop on language testing in Vietnam.

4.2.2 analysis of the results

This sub-section analyses the data gathered from the questionnaire survey. The information revealed in Tables 4.5 to 4.12 above can be generalized as follows: (1) most of the teachers are unable to distinguish the two functions of spoken language, (2) the majority of the teachers do not have a sufficient understanding of communicative language testing, (3) quite a number of the teachers fail to recognize the difficulty level of test tasks graded according to communicative stress, (4) the teachers have an inadequate understanding of oral language testing, and (5) the speaking tests in use lack authenticity.

Firstly, most of the teachers fail to distinguish the two different functions of spoken language in their own assessment criteria as discussed in 2.1 (Chapter 2). In particular, for Questions 1&2 (Tables 4.5&4.6), 11 out of 12 subjects give the lowest priority to option (g), that is the ability to speak at length. When taking transactional long turns, students are required to show their ability to express and convey their ideas at length. Nevertheless, the teachers at TNU hardly expect to see this feature in their students’ oral test performance.

Secondly, the notion of communicative language testing is not fully grasped and soundly engraved on many of the teachers’ mind. In this preferably applied approach to language testing as mentioned in 2.2 (Chapter 2), accuracy of language forms has turned out to be given a lower priority than communicative effectiveness in assessment. As revealed in Tables 4.5 and 4.6, the majority of the teachers, in their assessment criteria, give a high priority to options (a), (b) and (c) of both Questions 1&2. In particular, for Question 1, option (a) is given such a high priority by 4 subjects, (b) by 5 and (c) by 7; and for Question 2, option (a) by 5, (b) by 8 and (c) by 8. This implies that on average half of TNU English teaching staff give linguistic accuracy a high priority when evaluating their students’ production of spoken language.

good afternoon madam
what is system testing
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.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
