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.     

The tension in pre-service teachers’ explorations of tablet technology for literacy purposes: positive beliefs and practical shortcomings

Abstract

This mixed-method study sought to examine the experiences of a group of 21 pre-service teachers in a collegiate literacy education class which required a semester-long exploration of the potential of tablets to enhance the reading skills of youngsters. The quantitative portions of the study identified the participants’ daily use habits of electronic devices as well as their views on what is known as the new literacies. In the qualitative portions of the study, interviews and journal entries of the pre-service teachers were gathered relative to their experiences in devising literacy learning experiences using tablets. While these prospective teachers were avid users of electronic devises and confident in their abilities to use technology, they found considerable difficulty in preparing literacy-enhancing instruction which used tablet devices, which clearly points to the need for attention in teacher training programs to the use of tablet technology infused throughout teacher education courses.     

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.     

Cumulative Trauma Exposure and Mindfulness in College Students

The authors evaluated the cumulative effects of multiple trauma exposure and examined discrete mindfulness facets concerning trauma‐related outcomes among undergraduate students (N = 157). By using self‐report questionnaires, the authors found that higher trauma exposure was associated with more severe trauma symptomatology and psychological distress as well as lower quality of life. Furthermore, 4 mindfulness facets differentially predicted trauma outcomes. The authors discuss implications for college counseling counselors and researchers.     

Online self-assessment and peer-assessment as a tool to enhance student-teachers’ assessment skills

Self-assessment and peer-assessment are strategies employed to encourage students to take more responsibility for the learning process. Although the advantages are not obvious, the process has the potential to empower learning and to assist the development of assessment skills, which are so important for future teachers. The research aimed to identify student-teachers' attitudes concerning the contribution of self-assessment and anonymous peer-assessment to the quality of their assignments and improvement of their assessment skills, using both qualitative and quantitative methodologies. The sample included 300 students studying for bachelor’s or master’s degrees. Texts that were analysed included: responses to a questionnaire, self and peer-assessments, word comments on the assignments and written blog content relating to students’ activities and their performance of peer evaluations. The students noted that they significantly benefitted from the process, learned various methods of assignment and assessment performance and it positioned them in relation to others, noticing how others evaluated them. Anonymous evaluation allowed students to overcome inhibitions in evaluating peers' works and improved their assessment skills.     

Using cogenerative dialogues to improve coteaching for language learner (LL) students in an inclusion science classroom

This paper presents findings from a study conducted in an urban elementary school in the United States with an English language learner (ELL) student and two teachers engaged in collaborative teaching in an inclusion science classroom. This study examines the efficacy of utilising cogenerative dialogues between an ELL student and his science teacher and English as second language teacher to improve instructional practices enacted during coteaching. Drawing from field notes, teacher and student interviews, and video captured during cotaught science lessons and during cogenerative dialogues between the student and his coteachers, we examined the ways in which cogenerative dialogue expands teachers’ agency to adapt curriculum and implement instructional strategies that can better meet the needs of their students. At the same time, we examined the ways in which participation in cogenerative dialogues with his teachers expanded this student’s agency as a science learner and a language learner.     

Influences of electric field on living cells in a charged water-in-oil droplet under electrophoretic actuation

We experimentally investigate the effects of high electric field on living cells inside a charged droplet under electrophoretic actuation. When an aqueous droplet suspended in a dielectric liquid contacts with electrified electrode, the droplet acquires charge. This charged droplet undergoes electrophoretic motion under strong electric field (1–3 kV/cm), which can be used as a droplet manipulation method in biomicrofluidic applications. However, because strong electric field and use of dielectric oil can be a harmful environment for living cells, the biological feasibilities have been tested. Trypan blue test and cell growth test have been performed to check the viability and proliferation of cells in a droplet under various electric field strengths and actuation times. We have not observed any noticeable influence of electric field and silicone oil on the viability and proliferation of cells, which indicates that electrophoresis could be safely used as a manipulation method for a droplet containing living biological system.
