The role of two reading strategies in text comprehension: An eye fixation study in primary school children

This study examined whether 10–12‐year‐old children use two reading strategies to aid their text comprehension: (1) distinguishing between important and unimportant words; and (2) resolving anaphoric references. Of interest was the question to what extent use of these reading strategies was predictive of reading comprehension skill over and above decoding skill and vocabulary. Reading strategy use was examined by the recording of eye fixations on specific target words. In contrast to less successful comprehenders, more successful comprehenders invested more processing time in important than in unimportant words. On the other hand, they needed less time to determine the antecedent of an anaphor. The results suggest that more successful comprehenders build a more effective mental model of the text than less successful comprehenders in at least two ways. First, they allocate more attention to the incorporation of goal‐relevant than goal‐irrelevant information into the model. Second, they ascertain that the text model is coherent and richly connected.     

The consistency effect depends on markedness in less successful but not successful problem solvers: An eye movement study in primary school children

This study examined the effects of consistency (relational term consistent vs. inconsistent with required arithmetic operation) and markedness (relational term unmarked [‘more than’] vs. marked [‘less than’]) on word problem solving in 10–12 years old children differing in problem-solving skill. The results showed that for unmarked word problems, less successful problem solvers showed an effect of consistency on regressive eye movements (longer and more regressions to solution-relevant problem information for inconsistent than consistent word problems) but not on error rate. For marked word problems, they showed the opposite pattern (effects of consistency on error rate, not on regressive eye movements). The conclusion was drawn that, like more successful problem solvers, less successful problem solvers can appeal to a problem-model strategy, but that they do so only when the relational term is unmarked. The results were discussed mainly with respect to the linguistic–semantic aspects of word problem solving.     

Schoolteachers' constructions of desirable educational leadership: a career-stage perspective

The current study aimed at exploring desirable constructions of educational leadership among Israeli schoolteachers at three different career stages, as well as tracing the origins of these constructions. Based on semi-structured interviews with 10 teachers at early-career stage, 10 at mid-career stage and 10 at late-career stage, the study first found major commonalities among the interviewees with regard to emotional, moral, participative and structural constructions of educational leadership. But, ‘a second reading’ of the data unearthed subtle distinctions among the interviewees, deriving from the teacher's position in the career cycle. The early-career teachers hold an egocentric view of educational leadership while their late-career counterparts present a more multi-focal outlook. Empirical and practical implications are suggested.     

The effects of instruction on situation model construction: an eye fixation study on text comprehension in primary school children

This study examined whether the formation of a situation model can be encouraged by a situation‐focused instruction in primary school children. To achieve this, the standard reading‐for‐comprehension instruction was adapted so that it would emphasise the importance of imagination in narrative text comprehension. The results showed that the situational instruction enhanced the situation model construction abilities in good comprehenders in such a way that it improved not only their memory for the situation model but also the ease with which they filled in the gaps in time and space that appeared in the narratives. In poor comprehenders, the situational instruction led to a redistribution of attentional resources allocated to textbase‐ and situation‐level processing. It was suggested that this caused them to go beyond encoding the explicit text and instead construct a situation model from it, and that they did so without enriching the model with general‐knowledge inferences as much as good comprehenders.     

Electroplating for high aspect ratio vias in PCB manufacturing： enhancement capabilities of acoustic streaming

This paper considers the copper electrodeposit ion processes in microvias and investigates whether the quality of the electroplating process can be improved by acoustic streaming using megasonic transducers placed into a plating cell. The theoretical results show that acoustic streaming does not take place within the micro-via （either through or blind-via＇ s）, however it does help improve cupric ion transport in the area close to the mouth of a via. This replenishment of cupric ions at the mouth of micro-via leads to better quality filling of the micro-via through diffusion compared to basic conditions. Experiments showing the improved quality of the filling of vias are also presented.
