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.

Reading difficulties have reached a prevalence of 3–10% in school-age children. Those who present these difficulties avoid reading and benefit very little from school-based learning opportunities, resulting in maladjustments, dropping out of school and having to repeat grades. Presented here are the results of an intervention based on a computer game intended for explicit phonic training in first-grade school children at risk of possessing reading difficulties. Fifty-six children from a low socioeconomic status (SES) and 31 children from a high socioeconomic status, divided into two groups (control and experimental), participated in the study. After the intervention, participants from the low-SES experimental group had enhanced their skills regarding letter sound recognition, whereas the high-SES experimental group had improved their naming speed. The results are discussed in light of the impact of interventions based on computer games and of the importance of the development of sublexical skills in children at risk of manifesting reading difficulties in transparent orthographies.

Executive functions (EF) are a set of processes that allow individuals to plan, monitor and organize tasks and thus play a key role in the development of reading and maths skills. Environmental factors such as socioeconomic level (SEL) influence reading and maths skills as well as EFs. The aim of this study is to explore the extent to which executive functions play a mediating role between SEL and reading and maths performance. To this end, we assessed 286 Chilean primary education students: 86 with a high SEL and 200 with a low level. The results show that the high-SEL group obtained consistently higher scores than their peers with low SEL levels in both reading and maths tasks as well as in EF measurements. This suggests that SEL could influence the development of these variables. The results also showed that EFs partially mediate the relation between SEL and reading and maths skills in primary school students through the specific function of inhibition. The results are discussed in light of the effect of SEL on the development of EFs and school learning.

Background: The role of non-linguistic factors, such as executive functions, in the reading comprehension process has been analyzed. The present research sought to investigate the relationship between executive functions and reading comprehension. Methods: In an exploratory cross-sectional study, a group of 89 fourth-grade students were evaluated, considering a balanced number of children with and without reading comprehension difficulties. Results: The results indicate that students with reading comprehension difficulties present a lowered profile with respect to both executive functions and reading variables. The path analysis indicates the presence of differences in the variables that explain reading comprehension for both groups. While in the case of students without reading comprehension difficulties, working memory has both a direct and an indirect effect, i.e., through vocabulary, on reading comprehension; in the case of children with reading comprehension difficulties, only cognitive flexibility has a direct impact. In both cases, inhibition has an indirect impact through vocabulary. Conclusions: We reflect on the differentiated role of executive functions according to the level of development of reading skills, highlighting the possibility that some skills may act in a compensatory manner in the presence of general difficulties. The role of vocabulary in the relationship between executive skills and reading is highlighted.

This research aims to evaluate the predicting role of executive functions, specially inhibition and flexibility, in reading comprehension. Participants were evaluated with inhibition and flexibility measures in first- grade, and later in third- grade their reading comprehension, oral and silent reading fluency, as well as their decoding skills were measured. Results show that first grade inhibition and flexibility are direct predictors of third- grade reading comprehension. When the indirect effect of inhibition and flexibility on reading comprehension was tested through measures of reading fluency and decoding, it was found that neither ORF nor decoding mediates the relationship between the variables. However, it was found that SRF is a variable that mediates the relationship between flexibility and reading comprehension. Results are discussed in the context of the relevance of early measures of inhibition and flexibility to explain reading comprehension and the role of SRF in this relationship.

This special issue is devoted to the study of reading and writing in Spanish focusing on their particularities from the perspective of its orthographic depth. Research has exposed the role characteristics from different orthographic systems play, explaining how reading and writing are learned and the cognitive processes involved in those learning processes. Through their research and reflection the various Latin American authors — and a special contribution by a Finnish author — describe the differences in reading processes in transparent orthographic systems as well as the future direction the study of reading may take from the perspective of their orthographic qualities.
