Preservice teachers’ and teachers’ conceptions of energy and their ability to predict pupils’ level of understanding

The study examined (a) the extent to which teachers and preservice teachers understand the concept of energy and adhere to particular preconceptions associated with it; and (b) their ability to predict pupils’ knowledge and understanding of the same concept. Teachers and preservice teachers completed a test by indicating for each item what their response was and what an average sixth-grade pupil’s response might have been, and their predictions were compared to actual pupil performance. Results indicated that teachers’ and preservice teachers’ understanding of the concept was far from complete, and that teachers were, in general, more likely to overestimate pupils’ knowledge.     

Reading argumentative texts: comprehension and evaluation goals and outcomes

The study is situated at the interface between reading comprehension and critical thinking research. Its purpose was to examine the influence of reading goals and argument quality on the comprehension and critical evaluation of argumentative texts. Young adult readers read to comprehend or evaluate texts on two different controversial issues. Argument quality was varied across text versions on the basis of the hasty generalization fallacy. Text versions varied with respect to the quality of the arguments included, but not in terms of argument content. Measures of comprehension included main claim recall, overall recall and inferences in recall. Text evaluation was measured with a rating task. The sample’s familiarity with the text topics was low, and prior beliefs were relatively neutral. The results indicated that an evaluation goal had a consistent positive effect on main claim and text recall when compared to comprehension goal. Argument quality, however, had no main or interactive effects on text evaluation. The findings indicate that reading to evaluate argumentative text facilitates the representation of its content and critical argument elements, such as the claim it promotes. However, this representation is not sufficient for analyzing and critically evaluating the text’s argument line. The implications of these findings are discussed in relation to current efforts to promote critical-analytic thinking skills in the context of reading and writing.     

The role of reading comprehension in word meaning acquisition during reading

The purpose of this study was to explore the influence of reading comprehension on the acquisition of word meanings from context and to compare it to the effects of local context characteristics, such as proximity and directness of context clues. The study also examined the effects of prior topic and enabling concept knowledge. Sixth-grade students were pretested on their knowledge of target vocabulary from two expository passages appropriate for their grade and reading level. The students were then familiarized with selected main concepts from one passage and, subsequently, read both experimental passages. Half of the target words appeared in an informative context, while the rest appeared in an less-informative context. A comprehension test and a vocabulary posttest followed the reading of each passage. Hierarchical Regression analyses indicated that reading comprehension level and prior main concept knowledge facilitated vocabulary learning from context. In comparison, the effect of presence or absence of informative context clues was not significant. These findings, underline the need for a reconceptualization of context to take into account the mental representation that readers construct in addition to the printed text that surrounds an unfamiliar word.
