The effects of multimodal texts on science reading comprehension in Chilean fifth-graders: text scaffolding and comprehension skills

ABSTRACT

Reading comprehension is a crucial skill that elementary school students must develop in order to learn science. However, there is not yet enough research about the role that multimodal texts play in scaffolding student reading comprehension of complex scientific processes, such as energy transfer. This study explored how verbal and visual resources (scaffolding level) and individual differences (reading skills) contribute to science reading comprehension. One-hundred and sixty Chilean fifth-graders were assessed on reading skills, vocabulary, and prior science knowledge. A counterbalanced design was used to test two groups: Group 1 reads a text with low multimodal scaffolding and Group 2 reads a text with high multimodal scaffolding. Level of text scaffolding was determined by (1) image function, (2) visual-verbal relations, (3) presence of an explicit explanatory structure, and (4) lexico-grammatical resources. General monomodal and multimodal science reading comprehension were assessed with multiple-choice tests. An ANCOVA analysis revealed non-significant differences between groups after controlling for prior knowledge, fluency, and vocabulary. Likewise, a two-factor ANCOVA analysis showed that the high-multimodal scaffolding text significantly boosted science reading comprehension for low-skilled comprehenders. The paper discusses the implications of these findings for pedagogy and research, aiming to foster multimodal literacy for learning in content areas.     

Exploring the effect of background knowledge and text cohesion on learning from texts in computer science

In this study, we examine the effect of background knowledge and local cohesion on learning from texts. The study is based on construction–integration model. Participants were 176 undergraduate students who read a Computer Science text. Half of the participants read a text of maximum local cohesion and the other a text of minimum local cohesion. Afterwards, they answered open-ended and multiple-choice versions of text-based, bridging-inference and elaborative-inference questions. The results showed that students with high background knowledge, reading the low-cohesion text, performed better in bridging-inference and in elaborative-inference questions, than those who read the high-cohesion text. Students with low background knowledge, reading the high-cohesion text, performed better in all types of questions than students reading the low-cohesion text only in elaborative-inference questions. The performance with open-ended and multiple-choice questions was similar, indicating that this type of question is more difficult to answer, regardless of the question format.     

Key skills for science learning: the importance of text cohesion and reading ability

To explore the importance of text cohesion, we conducted two experiments. We measured online (reading times) and offline (comprehension accuracy) processes for texts that were high and low cohesion. In study one (n?=?60), we manipulated referential cohesion using noun repetition (high cohesion) and synonymy (low cohesion). Students showed enhanced comprehension accuracy and faster comprehension responses for text that were high in referential cohesion. In study two (n?=?52), we examined connective text designs (‘because’, ‘and’ and ‘no connective’). Students demonstrated enhanced reading times for text using a ‘because’ connective. Additionally, we examined the individual differences (reading ability, science self-concept and self-esteem) as predictors of achievement with science comprehension tasks. Across both experiments reading ability predicted comprehension with both high (noun-repetition text and ‘and’ text) and low cohesion text (synonym text and ‘no connective’ text). These findings highlight the importance of good reading abilities and text cohesion for promoting science comprehension and learning.     

Developmental dynamics of metacognitive knowledge and text comprehension skill in the first primary school years

The aim of this study was, firstly, to explore the development of primary school children’s metacognitive knowledge from preschool to the 2nd grade and the development of their text comprehension skill from the 1st grade to the 3rd grade. Secondly, the developmental dynamics between metacognitive knowledge (MCK) and text comprehension skill (CS) across the first three school years were investigated. The longitudinal sample included 181 children who were tested three times from preschool spring to the spring term of the 3rd grade using an identical set of measurements: the Metacognitive Knowledge Test and Listening and Reading Comprehension Tests. In studying developmental change using Latent Growth Curve modelling (LGC), no uni-construct effect for the development of MCK or for text CS was found. However, a slight multi-construct cumulative development between the children’s MCK and reading CS was identified. Thus, it could be cautiously interpreted that the more the children’s MCK developed from preschool to the end of the 2nd grade, the better reading CS they showed during the first three school years.

Lexical inference in L2: predictive roles of vocabulary knowledge and reading skill beyond reading comprehension

The current study examined the predictive roles of L2 vocabulary knowledge and L2 word reading skills in explaining individual differences in lexical inferencing in the L2. Participants were 53 Israeli high school students who emigrated from the former Soviet Union, and spoke Russian as an L1 and Hebrew as an L2. L2 vocabulary knowledge and decoding accuracy predicted L2 reading comprehension, which in turn was strongly related to lexical inferencing abilities in the L2. In addition, decoding accuracy predicted additional variance in lexical inferencing, beyond the role of reading comprehension. These findings support the idea that beginning L2 readers with more precise and efficient lexical representations demonstrate better lexical inferencing abilities, most likely due to the increased automatization of word reading, which frees up resources for higher level processing. These results suggest that lexical inferencing from text in the L2 might be limited not only by vocabulary knowledge and higher order comprehension processes, but also by basic decoding skills.     

Reader and text factors in reading comprehension processes

The effects of epistemic beliefs and text structure on cognitive processes during comprehension of scientific texts were investigated. On‐line processes were measured using think‐aloud (Experiment 1) and reading time (Experiment 2) methodologies. Measures of off‐line comprehension, prior knowledge and epistemic beliefs were obtained. Results indicated that readers adjust their processing as a function of the interaction between epistemic beliefs and text structure. Readers with misconceptions and more sophisticated epistemic beliefs engage in conceptual change processes, but only when reading refutation texts. Results also showed that memory for text is not affected by differences in epistemic beliefs or text structure. These findings contribute to our understanding of the relations among factors associated with text comprehension and have implications for theories of conceptual change.

An evaluation of two approaches for teaching reading comprehension strategies in the primary years using science information texts

There are few research studies on the effects of teaching comprehension strategies to young children in the primary grades. Using a Dominant–Less Dominant Mixed Model design employing both qualitative and quantitative data collection, we evaluated two approaches for teaching comprehension strategies to 7- and 8-year-old children in four second-grade classrooms using science information texts. The first approach focused upon explicitly teaching a series of single comprehension strategies, one-at-a-time (SSI). The second approach focused on teaching a “set” or “family” of transacted comprehension strategies within a collaborative, interactive and engaging routine (TSI). Results showed no difference between teaching young children a “set” of comprehension strategies and teaching comprehension strategies explicitly, one-at-a-time on their reading comprehension performance as measured by a standardized test of reading comprehension, recall of main ideas from reading two 200 word passages from information texts, a reading motivation survey and a strategy use survey. Results showed significant differences between students taught a set of comprehension strategies on measures of elaborated knowledge acquisition from reading science books (detail idea units recalled), retention of science content knowledge, and significantly improved criterion or curriculum-based reading comprehension test scores. These benefits favoring TSI over SSI are important because the learning curve is relatively steep for teachers to develop the ability to teach and for young children to develop the ability to coordinate a “set” of transacted comprehension strategies.     

Effects of a peer-mediated phonological skill and reading comprehension program on reading skill acquisition for middle school students with reading disabilities

The purpose of this study was to examine the effect of a peer-mediated instructional approach on the teaching of phonological skills and reading comprehension for middle school (sixth- to eighth-grade) students with reading disabilities. All students (n = 38) were identified as having learning disabilities and reading at the third-grade level or below. One group was taught using a peer-mediated phonological skill program, Linguistics Skills Training (LST), and a peer-mediated reading comprehension program, Peer Assisted Learning Strategies (PALS). The contrast group was taught in the more traditional whole-class format using a widely implemented remedial reading program. The results showed significant differences between conditions, with students receiving the LST/PALS instruction outperforming the contrast group on Letter-Word Identification, Word Attack, and Passage Comprehension using the Woodcock-Johnson Test of Achievement-III. Furthermore, large effect sizes for growth were found on Letter-Word Identification, Word Attack, and Passage Comprehension for the LST/PALS treatment group. No differences were found between conditions for reading fluency. Findings are discussed in regard to instruction delivery format (peer tutoring vs. whole class) with respect to best practices for middle school students with reading disabilities.     

Mediation in the relationship among EL status,vocabulary, and science reading comprehension

The authors investigated the mediating effects of general academic and science-specific vocabulary on science reading comprehension among English learners (ELs) of varied proficiency. The sample included 169 regular education Grade 7 students (86 current ELs; 83 former ELs) enrolled in 1 urban school in Pacific Northwest region of the United States. The results indicated that both vocabulary types—rarely explicitly taught at the secondary level—were significant contributors to reading comprehension, above and beyond EL status. The full parallel mediation model accounted for 55% of the variance in science reading comprehension. Notably, the mediating effects of both vocabulary types were significant and statistically similar in size, yet, not sufficient to fully explain ELs' reading scores. Implications and directions for future research are discussed.     

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.     

Impact of text availability and question format on reading comprehension processes

We conducted two experiments to analyze how text availability and question format affect readers’ processes and performance on measures of expository text reading comprehension. Junior high school students read expository texts and answered both multiple choice and open-ended questions on a computer that recorded reading times and readers’ actions with Read&Answer software. The results showed that readers reread prior text segments during initial reading of the text more often when they knew that the text would be unavailable when answering questions than when they knew that the text would be available. In addition, readers made more search decisions in the text- available condition when answering open-ended questions than when answering multiple-choice questions. Regarding performance, we repeatedly found an interaction effect between availability and question format: text availability benefited the open-ended but not the multiple-choice format. We concluded that the two availability conditions are useful in assessing different discourse processes. We discuss theoretical and practical implications for the development of models of reading and new ways to assess reading literacy skills that emphasize purposeful reading.     

Investigating the contributions of background knowledge and reading comprehension strategies to L2 reading comprehension: an exploratory study

While a number of studies have investigated the influence of background knowledge and reading comprehension strategies on comprehension, no L2 research exists examining and comparing the unique contributions of these two variables examined together. Therefore, the purpose of this exploratory study was to investigate the combined and individual contributions of background knowledge and reading comprehension strategies to reading comprehension. Data collected from 20 university-level English language learners were analyzed using regression analyses. The results indicated that background knowledge and reading comprehension strategies, operationalized as self-questioning, combined to account for a significant portion of variance in reading comprehension scores, with self-questioning being a stronger predictor of reading comprehension than background knowledge.

Predicting reading comprehension of narrative and expository texts among Hebrew-speaking readers with and without a reading disability

The aim of this study was to investigate which cognitive and reading-related linguistic skills contribute to reading comprehension of narrative and expository texts. The study examined an Israeli national database of Hebrew-speaking readers in fourth grade, from which a subsample of 190 readers with a reading disability (RD) and 190 readers with no reading disability (NRD) was selected. IQ, text reading, reading comprehension, and various linguistic and cognitive skills were assessed. Structural equation modeling results suggested that both groups rely on lower level processes such as text reading accuracy and orthographic knowledge for reading comprehension of both genres. However, RD readers depend more heavily upon these lower level processes compared with NRD for whom higher level processes contribute more to reading comprehension. The various variables accounted for only 25-34% of reading comprehension variance, and possible explanations are discussed. Taken together, these findings highlight the variety of factors influencing reading comprehension and its multidimensional nature.     

Effects of different text display types on reading comprehension,sustained attention and cognitive load in mobile reading contexts

Despite the popularity of mobile reading devices, many studies have indicated that small screens restrict information transmission, adversely affecting reading performance on mobile devices. Moreover, mobile reading typically occurs in different reading contexts. Therefore, suitable text display type for mobile reading in different reading contexts should be considered, such that learners can effectively read content. This work selected the frequently used static and dynamic text display types (i.e. Paging and Auto-scrolling) and assessed their effects on mobile reading performance. Furthermore, the features of static and dynamic text display types were considered when designing a mixed text display type for mobile reading. Based on brainwave detector, reading-comprehension test sheet, and cognitive-load scale, this work designed a mobile reading experiment with a two-factor experimental design to assess the effects of the selected static, dynamic, and designed text display types, which were respectively presented in sitting, standing, and walking contexts, on reading comprehension, sustained attention, and cognitive load of learners. Experimental results show that sitting obtained the highest sustained attention and the mixed text garnered lowest sustained attention. Moreover, although analytical results show that no significant difference existed in overall reading comprehension with each text type presented with the mobile reading contexts, reading comprehension (i.e. memory, comprehension, and application types) was significantly affected by the reading context, and to some degree, the text display type. This work also found that the text display type is a major factor affecting learners' cognitive load; however, learners' cognitive load is not be affected by the considered reading contexts. Among the three text display types, the mixed type generates the highest cognitive load, followed by the dynamic type, and then the static type. In conclusion, the three reading contexts with the three text display types have both advantages and disadvantages for reading comprehension, sustained attention, and cognitive load. As a result, text display type for mobile reading on small screens should be adjusted according to reading context or to improve reading comprehension, attention, or cognitive load.     

Gender differences in reading: Examining text-based interest in relation to text characteristics and reading comprehension

Reading is a key competence for knowledge acquisition and learning processes. One important source of reading motivation is interest. Even though students' text-based interest often differs by gender, it remains unclear which text factors underlie these differences and whether text-based interest relates to reading comprehension among boys and girls. In a sample of 514 elementary students (47.2% girls), this study examined whether text topic, protagonists' gender, and text difficulty affect boys' and girls' text-based interest and whether interest and reading comprehension are intertwined. Based on a repeated within-subject design using fourteen narrative texts, the results indicated that boys' interest was higher in texts with male-attributed topics, male protagonists, and in more difficult texts. In contrast, girls’ interest was only affected by text difficulty. Text-based interest and reading comprehension were significantly related, albeit stronger for boys than for girls. The findings are discussed regarding future implications for research and educational practice.
