The impact of L1 writing system on ESL knowledge of vowel and consonant spellings

Orthographic knowledge, the general ability to learn, store, and use information about the orthographic form of words (Stanovich & West, 1989), is a crucial skill for supporting literacy. Although the development of first language (L1) orthographic awareness is impacted by the characteristics of a learner’s L1 writing system, relatively little is known about what impact the L1 may have on second language (L2) orthographic awareness. In this study, English language learners from three L1s (French, Hebrew, Mandarin Chinese), plus L1 English speakers, were tested on their English spelling knowledge using a word-pseudohomophone discrimination task. In addition to allowing for the cross-linguistic comparisons, items were designed to examine whether learners had differing performance on pseudohomophones (misspellings) that targeted vowels versus consonants. Consistent with previous research (e.g., McBride-Chang, Bialystok, Cong, & Li, 2004), the L1 Chinese speakers had the highest (L2) accuracy, followed by the L1 Hebrew and the L1 French speakers. The participants from non-alphabetic languages (Hebrew and Chinese) had significantly lower accuracy on items with misspellings involving vowels compared to consonants, and the size of the vowel-consonant accuracy difference varied substantially across L1 groups. The results demonstrate that the characteristics of a learner’s L1 writing system, particularly the existence of vowel and consonant graphemes, impact the development of L2 orthographic knowledge and sensitivity to different types of word misspellings.     

Scaffolding reflection and articulation of scientific explanations in a data-rich,project-based learning environment: An investigation of progress portfolio

In this study, we examined how learners developed scientific explanations about light with the assistance of various technology-based scaffolds. The study emphasis was on scaffolding processes of reflection and articulation. We used a content-neutral software program (Progress Portfolio) to create the instructional scaffolds. A qualitative research design was used to investigate two pairs of prospective teachers in a science content course in engineering. Our findings suggested that the computer-based scaffolds used in our study were useful to support articulation, reflection, and revision of explanations, when certain conditions were met. A major theme of our findings relates to interacting effects among learner characteristics, teacher coaching, software scaffolding design, and task characteristics.

Vocabulary does not complicate the simple view of reading

Gough and Tunmer’s (1986) simple view of reading (SVR) proposed that reading comprehension (RC) is a function of language comprehension (LC) and word recognition/decoding. Braze et al. (2007) presented data suggesting an extension of the SVR in which knowledge of vocabulary (V) affected RC over and above the effects of LC. Tunmer and Chapman (2012) found a similar independent contribution of V to RC when the data were analyzed by hierarchical regression. However, additional analysis by factor analysis and structural equation modeling indicated that the effect of V on RC was, in fact, completely captured by LC itself and there was no need to posit a separate direct effect of V on RC. In the present study, we present new data from young adults with sub-optimal reading skill (N = 286). Latent variable and regression analyses support Gough and Tunmer’s original proposal and the conclusions of Tunmer and Chapman that V can be considered a component of LC and not an independent contributor to RC.     

Science Classroom Interactions and Academic Language Use with English Learners

Academic language is critical for English learners (ELs) to succeed in the science classroom. This study analyzed the instructional practices centered around academic language taking place in eight, fifth-grade classrooms during a grant-funded project. Observational data collected through a classroom observation instrument were analyzed to describe and compare the instructional practices occurring in treatment and control classrooms when teachers and students used academic language. Our findings show both treatment and control classrooms using academic language during the course of the intervention study, but the instruction looked markedly different in each setting. These differences provide valuable insight for practitioners and researchers concerned with the academic language development of ELs in science classrooms.     

Speech perception and speech production as indicators of reading difficulty

In order to investigate the relation between reading accuracy and speech processing, 20 children from grades 2 and 3 who were skilled in reading were compared with 20 less skilled readers on a speech perception and production task. The two groups of readers were indistinguishable in their production of the two-syllable words dippy, deepy, tippy, and teepy and in their perception of the stop consonants /d/ versus /t/. Less skilled readers were significantly less accurate than the skilled readers in a vowel identification task involving the lax and tense high vowels /i/ and /i/. The error pattern for vowel identification was similar across groups, with both groups making fewer errors when short and longer segments were alternated. The results imply that vowel phonemes are less securely represented in the perceptual system of less skilled readers than are consonant phonemes. In addition, the results raise the possibility that a selective perceptual impairment underlies at least some of the phonemic awareness problems that have been associated with poor reading.     

Early intervention for reading disabilities: teaching the alphabet principle in a connectionist framework

Forty-eight children referred by teachers at the end of first grade for difficulty in reading were randomly assigned to three treatments, all of which modeled connections between written and spoken words but did not teach phonics rules, for eight half-hour individual tutoring sessions. The children were taught 48 words of varying orders of spelling-sound predictability (Venezky, 1995) using a whole-word method, for making connections between a word's name and its constituent letters; a subword method, for making connections between each color-coded spelling unit and its corresponding phonemes; or a combined whole-word and subword method. Regardless of the method used, children improved reliably on standardized reading measures and the taught words, showing that they could make connections between written and spoken words at the whole word and subword levels, even when rules were not taught. By posttest, the subword method showed a reliable advantage on a standardized test of real word reading. Knowledge of sounds associated with both multiletter and single-letter spelling units predicted reading achievement. Order of spelling-sound predictability (easy, moderate, difficult) was correlated with standardized measures of reading at pretest and posttest, and the magnitude of the relationship increased as a result of the intervention. Individual differences in verbal intelligence, rapid automatized naming, and phonological and orthographic skills predicted response to the intervention. Instructional implications of the results are discussed.     

Establishing a Quality Literature Base: Barriers that African Americans Face in Becoming Teachers

Researchers have long documented the need for increased representation of African American teachers in the United States teacher workforce. However, much of the resulting literature has been unsuccessful in eliciting change, as it does not explain why this need for increased representation persists. To address this gap, various researchers have turned to documenting the barriers which exist for African Americans at multiple stages of the process of becoming a teacher. This paper reviews, summarizes, and critiques this literature in order to document and describe the current depiction of the context of becoming a teacher for African Americans. Limitations in the literature are described based on Padilla (Handb Res Multicult Educ 2:127–145, 2004), and future steps to accommodate for and surpass the weaknesses of the current literature are provided.
