An Overall Study on Automated Writing Evaluation

Automated Writing Evaluation(AWE) program is designed to provide instant scores based on automated writing scoring engine along with diagnostic feedback. Five main AWE programs are introduced, four invented by foreign companies and one by Chinese native company for Chinese students. This paper reviews studies on AWE home and abroad from perspectives of its validity and instructional application. These studies have shown that AWE program should be used as an instructional tool to improve writing skill rather than only as a scoring and feedback engine. So how to implement and integrate AWE program into instructional context and to achieve more desirable learning outcomes while avoiding potential harms should be the focus of study for the future research.     

‘Consider the Opposite’ – Effects of elaborative feedback and correct answer feedback on reducing confirmation bias – A pre-registered study

Unbiased reasoning is considered an essential critical thinking skill that students need to possess to face the future challenges in their work and life. Confirmation bias, which is the tendency to selectively attend to information that is consistent with held beliefs, presents a significant thread to unbiased reasoning. An effective strategy to reduce confirmation bias is the ‘consider-the-opposite’-strategy (COS). The central question of this pre-registered study was whether providing elaborative, worked example feedback after COS practice would lead to a better performance on previously practised and transfer tasks than correct-answer feedback. Participants were 132 university students who took a confirmation bias pre-test, watched an instructional video on COS afterwards and next received either worked example feedback or correct answer feedback on practice tasks, practised only, watched the instruction only or received no treatment. Finally, all participants took a learning test assessing their skill to avoid confirmation bias, and a transfer test assessing whether they could apply this acquired skill to problems containing other biases. Results revealed no differences on the learning test between both feedback conditions, but students who received feedback scored significantly higher on the confirmation bias problems than students who did not receive feedback. We carried out our pre-registered analysis plan, but due to the low reliability of particularly the pre-test, we carried out an additional exploratory analysis on subsets of post-test items and a subset of transfer test items. Results on learning revealed the same pattern as the planned analyses. However, we found no differences between any of the conditions on transfer.     

The use of speech feedback by normal and disabled readers in computer-based reading practice

Disabled readers and normal beginning readers were compared on requesting help in the form of speech feedback during computer-based word reading. It was also examined whether it is best to give feedback on all words or to allow the disabled readers to choose. Normal beginning readers and reading-age matched pupils with reading problems engaged in reading practice with speech feedback on call for both difficult and easy words. A set of both difficult and easy sums was completed as a control task. Another group of reading-disabled pupils who were also matched on reading level practiced the reading of words with unsolicited speech feedback. In the first two groups the selectivity in requesting help in both the reading and arithmetic task was assessed. All subjects were tested on the reading of both practiced and nonpracticed words. The results indicate that both disabled readers and beginners were very sensitive to sum difficulty but not to word difficulty, though in the present study the students were more selective than in a previous study. The inclusion of more easy words might account for this finding. The beginners requested help only during the first sessions of reading practice, whereas the disabled readers remained dependent on the speech feedback. The reading-disabled pupils did not learn less when the computer unsolicitedly delivered the spoken form of all words than when they were allowed to choose. It is discussed how profits from the different speech feedback procedures by disabled readers might be related to word decoding skill and metacognitive monitoring.     

I am not unskilled and unaware: deaf and hearing learners’ self-assessments of linguistic and nonlinguistic skills

The unskilled and unaware effect refers to the finding that individuals who are less knowledgeable or less skilled in a domain are relatively less able to evaluate their level of skill or effectively utilise feedback relative to individuals who are more skilled. Studies finding deaf students less accurate than hearing students in estimating their English vocabulary knowledge and in judging how much they are learning from material presented via sign language have attributed those results to the unskilled and unaware effect, citing the lack of language fluencies frequently demonstrated among deaf learners. The present study addressed the issue more directly by comparing both deaf and hearing individuals who were more and less skilled in four domains, three linguistic and one nonlinguistic. Results indicated that even individuals who are unskilled in a nonlinguistic domain can evaluate their performance when they are aware of what skilled performance would look like, and that unskilled and unaware effects can be influenced by individuals’ desires to be skilled.

The role of feedback in young people’s academic choices

ABSTRACT

Women are underrepresented in Science, Technology, Engineering and Mathematics subjects with more girls leaving these subjects at every stage in education. The current research used a scenario methodology to examine the impact of teacher feedback on girls’ and boys’ choices to study a specific science subject, engineering. British participants aged 13 (N?=?479) were given scenarios where a new teacher encouraged them to take engineering using person feedback which focussed on their abilities, process feedback which focussed on their effort levels or gave them no reason. Results suggested that both boys and girls were more likely to select to study engineering when they received person feedback rather than process or no feedback. Young people also thought that ability was more important to being successful in science than in non-science subjects.This suggests young people feel that ability is needed to succeed in science subjects and person feedback can lead them to believe that they have this ability. Therefore, teacher feedback which gives ability attributions for possible success could be used to encourage more young people to persist in science. However, the potentially negative longer term outcomes of ability attributions and how they may be negated are also discussed.

Behavioural sequential analysis of using an instant response application to enhance peer interactions in a flipped classroom

To stimulate classroom interactions, this study employed two different smartphone application modes, providing an additional instant interaction channel in a flipped classroom teaching fundamental computer science concepts. One instant interaction mode provided the students (N?=?36) with anonymous feedback in chronological time sequence, while the other showed their feedback by “like” ranking (N?=?26). The behavioural patterns of undergraduates using these two different modes were compared. The results showed that the like-ranked feedback deepened the interaction between asking and answering questions, reduced the number of irrelevant messages, and increased attention to questionable messages. The students using the like-ranking mode also received more encouragement during the flipped classroom discussion activities.     

How emotionally intelligent are pre-service teachers?

Although there is evidence that teacher emotional intelligence is important for pupil adjustment and learning and for teachers in managing the emotional demands of their work, little is known about the levels of emotional skill of teachers and beginning teachers. Using Mayer and Salovey's emotional intelligence (EI) model and the MSCEIT test of EI, this study investigates how emotionally skilled student teachers are (N = 352). Results show lower than average levels of EI among student teachers, but with important differences between students and across emotional skill areas. The implications of the findings for pre-service teacher education are explored.
