Self-regulation in text processing

In this paper an experiment is reported on the influence of two variations of instructions on learning performance and thinking-aloud protocols of 64 pupils from secondary schools. Furthermore, differences between successful and less successful pupils in self-regulatory processes during text processing are described. The texts consisted of instructions on how to use a computer keyboard and a text-editor. Learning performance referred to both knowledge and application. The variation in instructions did not influence the learning performance and the thinking-aloud protocols (either quantitatively or qualitatively), but the variable Marks/No Marks did. The main differences between successful and less successful pupils occurred in orientation processes, especially with regard to Reflection on Foreknowledge and Gaps in Foreknowledge. Differences also turned up for processes such as Process Selection and Making Summaries. The results are discussed in light of the results from a prior study with an informative text.     

Text-belief consistency effect in adolescents´ comprehension of multiple documents from the Web (El efecto de consistencia en la comprensión lectora de los adolescentes de documentos múltiples provenientes de Internet)

ABSTRACT

Readers often comprehend belief-consistent information from multiple texts better compared with belief-inconsistent information (text-belief consistency effect). The aim of the present study was to investigate whether adolescents’ comprehension of multiple texts is similarly impacted by their beliefs. Moreover, readers’ prior knowledge and an alternating (compared with a blocked) mode of presenting multiple texts were expected to attenuate the text-belief consistency effect. High school students read two belief-consistent and two belief-inconsistent texts on one of two scientific issues in different modes of presentation (blocked vs. alternating). A recognition task was used to assess situation model strength for each text, and prior beliefs and prior knowledge were measured before the main experiment. As expected, in the blocked mode of presentation high school students had a stronger situation model for belief-consistent texts. In the alternating mode of presentation, participants had similar situation model strengths for the different texts. Moreover, high-knowledge participants experienced a text-belief consistency effect, whereas low-knowledge participants had weaker and similar situation models for the texts.     

What animated illustrations conditions can improve technical document comprehension in young students? Format, signaling and control of the presentation

We study the comprehension of a multimedia technical document about gear functioning by young pupils. The research is focused on the effect of three factors on the construction of a mental model: illustration format (animated versus static) signaling cues (presence versus absence) learner-control of information delivery (three rhythms of presentation: speed, slow and self-controlled). The experimental procedure, conducted with 123 children, follows three phases: pre-test, individual passation of the lesson, comprehension test, delayed post-test. The goal of the pre-test is the evaluation of prior knowledge about gears, but also the control of spatial and verbal working memory aptitude and reading performance. The results show an effect of the animated format, of signaling cues and of the rhythm on the immediate comprehension test and delayed test. For the immediate comprehension test, these effects are different according to the kind of comprehension question (recall, transfer, explanation). These effects are maintained at the delayed post-test, for the self-controlled condition and for the pupils with low prior knowledge. The factor information delivery rhythm shows an effect for the delayed post-test. Our observation device of the behaviour of the child during the lesson was specially designed to explore the reading strategies between the medias.     

Individual variation in children's reading comprehension across digital text types

The present study examined children's digital text comprehension of digital text types linear digital text vs hypertext, with or without graphical navigable overviews. We investigated to what extent individual variation in children's comprehension could be explained by lexical quality (word reading efficiency and vocabulary knowledge), cognitive load factors (prior knowledge and working memory), text type and graphical overview. Participants were 93 sixth graders in a within‐subject design. Word reading efficiency, vocabulary knowledge and prior knowledge predicted children's digital comprehension scores, while working memory did not. Reading comprehension was equal for linear text or hypertext. However, the presence of an overview facilitated reading comprehension for readers with lower prior knowledge. It can be concluded that hypertexts with basic digital text features and accompanying comprehension questions are not more difficult for children than linear digital texts, that similar individual factors predict reading comprehension of linear text and hypertext, and that a graphical overview helps when prior knowledge is low.     

The comprehension of first and second-language prose

How does national culture interact with second-language reading comprehension? This study investigated the effect of cultural medium of presentation, language, and sequence of cultural/foreign and first-language/second-language presentation on the literal and interpretative comprehension of Form I (seventh grade) bilingual Nigerian students. Data were analysed using ANOVA. Previous studies concerning schema theories were upheld in that the present results for Experiment 1 revealed significantly superior scores for culturally related English language text when compared with scores for foreign-based passages written in English. The data from Experiment 2 also revealed similar results when the subjects were presented with the same Experiment 1 foreign-based passages written in English and with translations of these English passages to the mother tongue. In spite of sequencing, scores were higher for the first-language passages. For both experiments, scores were higher at the literal level and sequencing was found to have little effect in enhancing comprehension of culturally unfamiliar material.     

The impact of sequencing and prior knowledge on learning mathematics through spreadsheet applications

According to cognitive load theory, instruction needs to be designed in a manner that facilitates the acquisition of knowledge in long-term memory while reducing unnecessary demands on working memory. When technology is used to deliver instruction, the sequence in which students learn to use the technology and learn the relevant subject matter may have cognitive load implications, and should interact with their prior knowledge levels. An experiment, using spreadsheets to assist studient learning of mathematics, indicated that for studients with little knowledge of spreadsheets, sequential instruction on spreadsheets followed by mathematics instruction was superior to a concurrent presentation. The reverse was found for studients with more knowledge of spreadsheets. These results are explained in terms of cognitive load theory.     

Relevant prior knowledge moderates the effect of elaboration during small group discussion on academic achievement

This study set out to test whether relevant prior knowledge would moderate a positive effect on academic achievement of elaboration during small-group discussion. In a 2 × 2 experimental design, 66 undergraduate students observed a video showing a small-group problem-based discussion about thunder and lightning. In the video, a teacher asked questions to the observing participants. Participants either elaborated by responding to these questions, or did not elaborate, but completed a distraction task after each question. They received either relevant or irrelevant prior knowledge before the discussion. After the discussion, all participants studied a text about thunder and lighting and completed immediate and delayed-recall tests for this text. Elaboration had no main effect on recall, but there was a significant interaction effect between relevant prior knowledge and elaboration. The results suggest that elaboration is helpful for students with more prior knowledge, but harmful for students with less prior knowledge.     

The relation of knowledge of textual integration devices to expository text comprehension under different assessment conditions

In this study we propose a theoretical construct (called rhetorical competence) that represents the ability of readers to detect, understand, and use the linguistic cues or discourse markers that texts contain. We measure one of the three postulated components of rhetorical competence (knowledge of textual integration markers), assessing whether readers correctly interpret these markers while reading. The influence of this skill on reading competence is examined in a correlational study of 185 sixth-grade pupils (aged 11–12 years) using different assessment materials (a standardized test and an academic text) and reading conditions (habitual and aided). Multiple regression analyses of the data indicate that knowledge of textual integration devices makes a significant independent contribution to expository text comprehension under most assessment conditions when the effects of working memory, prior knowledge, and word recognition skills are controlled.     

Fostering active processing of instructional explanations of learners with high and low prior knowledge

Despite the potential advantages of instructional explanations, evidence indicates that they are usually ineffective. Subsequent work has shown that in order to make instructional explanations effective indeed, one successful strategy is to combine them with indications of the limitations in learners' understanding that they are intended to revise, which makes learners deeply process the explanations. We explored whether this is so for both learners with low and those with high prior domain knowledge. In one experiment, 77 participants with low and high prior knowledge learned about plate tectonics from a multimedia presentation. In addition to the presentation, half the participants received instructional explanations combined with indications, whereas the rest received instructional explanations with no indications. After using the materials, the participants solved retention and transfer tests. Results showed that low prior knowledge learners learned more from explanations including indications of their misunderstandings, whereas high prior knowledge learners profited from instructional explanations either with or without the indications. We discussed theoretical and practical implications.     

L2-reading in the content areas: text comprehension in secondary education in the Netherlands

In the Netherlands, as in other Western European countries, many minority children are unsuccessful in their school careers. Their lack of achievement is associated with language and literacy problems. In secondary education they are faced with the task of text comprehension in the content areas, which is a reading task and a learning task at the same time. This study will report on the assessment of text comprehension in relation to vocabulary, grammar, non-verbal IQ and background knowledge about topics used in the text-comprehension test. Turkish and Dutch pupils took these tests during the first three years of their secondary schooling. In order to relate students’ different reading styles to their linguistic background (L1 or L2), three different subtests of text comprehension were used, each referring to a certain discourse level. It was found that the L2-readers tend towards a top-down approach of reading, which implies a stronger reliance on conceptual guidance than in L1-reading. With respect to the childen's reading development there was a significant increase in their scores for Word Knowledge and Non Verbal IQ, but there was no progress in the scores for Text Comprehension. Especially, Turkish pupils in the lowest type of the Dutch secondary-school system showed no progress at all.     

Gender,prior knowledge,interest, and experience in electricity and conceptual change text manipulations in learning about direct current

The present study investigated relationships between gender, interest and experience in electricity, and conceptual change text manipulations on learning fundamental direct current concepts. Conceptual change text has been shown to lead to better conceptual understanding of electrical concepts than traditional didactic text, but previous research suggested that the effect interacted with the gender of the participants. We hypothesized that interest moderated this interaction. In this study, men and women who had higher or lower interest in electricity and greater or lessor experience with electricity read conceptual change or traditional text. When interest level, experience, and prior knowledge were not included in the analysis, both gender and text type produced significant main effects. When interest level, experience, and prior knowledge were included in the analysis, conceptual change text led to better understanding of electricity concepts than did the traditional text, and the effect of gender was eliminated. This finding supports the hypothesis that prior interest level, experience, and knowledge mediate apparent gender differences in learning about electricity. It suggests that conceptual change text manipulations are likely to be effective for both men and women. © 1997 John Wiley & Sons, Inc. J Res Sci Teach 34: 107–123, 1997.     

Student teachers' prior knowledge as prerequisite to learn how to assess pupils' learning strategies

This study analyzed whether student teachers exhibit insufficient prior knowledge concerning learning strategies and whether different contexts lead to variations in activated knowledge. Furthermore, we investigated whether pieces of prior-knowledge and their structured-ness were associated with the assessment of pupils' learning strategies. In a within-subjects experiment (ABABAB design; N = 47 student teachers), questions about learning-strategy application referred to either (A) pupil-focused or (B) teacher-focused contexts. After a short training intervention, student teachers assessed strategies in pupils’ work. Different prior knowledge was elicited depending on contexts, suggesting “knowledge-in-pieces”. Prior-knowledge pieces, even if insufficient, served as a prerequisite to learn strategy assessment.     

Cognitive and linguistic predictors of text comprehension

The problem was concerned with the extent to which cognitive/linguistic functions and domain-specific strategies could predict readers’ text comprehension when working with science texts. Six hypotheses were stated and tested in two prediction studies (N=101 eighth-graders), and one experiment (N=8 pupils of same age). Handal’s reading test was used for classifying pupils into good and poor readers. Two texts, one with a known subject and another with an unknown theme were imposed pupils as science reading tasks. Questionnaires and tests concerning cognitive and linguistic functions were used as independent variables in the prediction studies. Two different tests were used as independent variables (for text comprehension) in all of the three studies, and one additional criterion test (writing essays on main ideas in the texts) was applied in the experient. The experiment was organized as a 2x2 factorial design where text type and reading skill were the factors. According to the results, 5 of the 6 hypotheses could not be rejected, i.e., general concept information was the most significant predictor of science text comprehension. Furthermore, text based on a subject known to the reader always surpassed text with an unknown subject as to text comprehension. Similarily, across-domain strategies were more closely related to reading comprehension than domain-specific strategies.     

Learning from expository texts: Effects of the interaction of prior knowledge and text structure on responses to different question types

The objective of this study was to verify the effects of the interaction between text structures and prior knowledge on memory and learning from expository texts. It examined the effects of two levels of prior knowledge and two types of mixed structures on a post-reading questionnaire. A total of 119 French-speaking, sixth-grade subjects were selected on the basis of a multiple-choice questionnaire. This questionnaire served to distinguish two groups, one possessing a high level of prior knowledge about the topic covered in the text (HP group), and another having a low level of prior knowledge (LP group). The children’s reading ability was evaluated by a cloze test that also served to eliminate children with reading comprehension difficulties from the experimental groups. The subjects in each group were arbitrarily assigned to subgroups. One group read an experimental passage, “The effects of acid rain on maple and pine”, which was organized in a collection inserted in cause/effect structure (SI). The other group read the same information, but which was organized in a comparison inserted in cause/effect structure (S2). The post-reading measure consisted of 24 questions that varied according to three criteria. The statistical analysis revealed that the effects of text structure were dependent on the level of prior knowledge and on the type of questions and confirmed that prior knowledge had a determining influence on knowledge acquisition.     

Learning from texts: activation of information from previous texts during reading

Learning often involves integration of information from multiple texts. The aim of the current study was to determine whether relevant information from previously read texts is spontaneously activated during reading, allowing for integration between texts (experiment 1 and 2), and whether this process is related to the representation of the texts (experiment 2). In both experiments, texts with inconsistent target sentences were preceded by texts that either did or did not contain explanations that resolved the inconsistencies. In experiment 1, the reading times of the target sentences introducing inconsistencies were faster if the preceding text contained an explanation for the inconsistency than if it did not. This result demonstrates that relevant information from a prior text is spontaneously activated when the target sentence is read. In experiment 2 free recall was used to gain insight into the representation after reading. The reading time results for experiment 2 replicated the reading time results for experiment 1. However, the effects on reading times did not translate to measurable differences in text representations after reading. This research extends our knowledge about the processes involved in multiple text comprehension: Prior text information is spontaneously activated during reading, thereby enabling integration between different texts.     

An investigation of children’s conceptualisation of computers and how they work

This paper reports on a study in which observation, stimulated recall and semi structured interviews were used to report on children’s knowledge and understanding of computer processes. It suggests a model for identifying stages in pupils’ understanding of these processes with implications for how best to support and develop that understanding. This was a small scale, exploratory case study involving data collection in two schools. The study differentiated between: simple awareness of computer processes; immediate knowledge of how to use an item or carry out a process; ability to offer a simple explanation for a process; and ability to offer a more sophisticated explanation and to use knowledge to solve problems. It was found that all pupils had an awareness of basic input, output and storage devices and a reasonable level of confidence and competence in using the computer. However, children’s knowledge tended to be confined to what they had acquired through experience. Interviews with the same pupils over a period of time showed little development in their conceptualisation of computer processes. Some examples of children’s common misconceptions as well as partial and appropriate conceptions are given. An implication for the classroom is that more dialogue between teacher and pupil, or more realistically between teacher and groups of pupils, is needed so that the teacher can ascertain prior knowledge and understanding and present accessible explanations for pupils.     

The impact of the teacher’s role and pupils’ ethnicity and prior knowledge on pupils’ performance and motivation to cooperate

How can the teacher bring about effective cooperative learning (CL) in multiethnic elementary classrooms? To answer this question we hypothesized that when the teacher stimulates pupils’ helping behaviour (experimental group), this increases pupils’ performance and CL motivation more than when the teacher lets pupils fend for themselves (control group). Subjects were 166 pupils from 10 schools. The results show that national pupils in the experimental group outperformed pupils in the control group and teams with low and medium prior knowledge performed better in the experimental group. Additionally, immigrant teams with high prior knowledge in the control group outperformed their low prior knowledge counterparts and had a higher CL motivation. Our results suggest that, next to the teacher’s role, attention has to be paid to both the pupil background characteristics ethnicity and prior knowledge and the teacher’s experience with CL.     

Early approach to theoretical thinking: gears in primary school

Gears are part of everyday experience from very early childhood. This paper analyses a teaching experiment conducted with 4th graders in the field of experience of gears. The aim is to identify the characteristics which, given a suitable sequence of tasks and proper teacher guidance, have enabled the pupils to approach theoretical thinking, and in particular mathematical theorems. We have focused on the relationships between the epistemological analysis of some pieces of mathematical knowledge brought into play in tasks concerning gears, cognitive analysis of pupil construction of those pieces of mathematical knowledge, and didactic analysis of the teacher's role in designing tasks and in offering cultural mediation. This paper presents the early findings of the teaching experiments, both at the external level of interpersonal classroom processes and at the inner level of individual mental processes.
