Revising Strategy Instruction in Inclusive Settings: Effects for English Learners and Novice Writers

Twenty‐three students with varying academic and linguistic profiles were taught a strategy for revising expository essays, using the Self‐Regulated Strategy Development model for instruction. Students learned basic revising tactics and to consider text structure as they managed decisions on how to improve their essays. Instructional effects were assessed using a multiple baseline with multiple probes in baseline design. Positive results were found for English learners, including those who were identified as having learning disabilities, or who were low‐, average‐ and high‐achieving writers; moreover, results were equally positive for students who were not English learners. After instruction and 4 weeks later, students revised more, produced more revisions that improved text, and revised longer text segments, which resulted in an improvement in overall quality.     

Language Use in a Multilingual Class: a Study of the Relation Between Bilingual Students’ Languages and Their Meaning-Making in Science

In this study, we examine how bilingual students in elementary school use their languages and what this means for their meaning-making in science. The class was multilingual with students bilingual in different minority languages and the teacher monolingual in Swedish. The analysis is based on a pragmatic approach and the theory of translanguaging. The science content was electricity, and the teaching involved class instruction and hands-on activities in small groups. The findings of the study are divided into two categories, students’ conversations with the teacher and student’s conversations with each other. Since the class was multilingual, the class instruction was carried out in Swedish. Generally, when the conversations were characterised by an initiation, response and evaluation pattern, the students made meaning of the activities without any language limitations. However, when the students, during whole class instruction, were engaged in conversations where they had to argue, discuss and explain their ideas, their language repertoire in Swedish limited their possibilities to express themselves. During hands-on activities, students with the same minority language worked together and used both of their languages as resources. In some situations, the activities proceeded without any visible language limitations. In other situations, students’ language repertoire limited their possibilities to make meaning of the activities despite being able to use both their languages. What the results mean for designing and conducting science lessons in a multilingual class is discussed.     

A reciprocal peer review system to support college students' writing

As students' problem‐solving processes in writing are rarely observed in face‐to‐face instruction, they have few opportunities to participate collaboratively in peer review to improve their texts. This study reports the design of a reciprocal peer review system for students to observe and learn from each other when writing. A sample of 95 undergraduate students was recruited to construct texts with the support of web‐based reciprocal peer review in the processes of modelling, coaching, scaffolding, articulation, reflection and exploration. The results of the study revealed that these six processes helped students externalise and visualise their internal writing processes so that they could observe and learn from peers in writing as well as support peers in making text revisions. During their extensive and reciprocal interactions with various peers, students addressed mutual concerns in each other's text revisions. They constructed collaborative language knowledge for text improvement as local revisions (grammatical corrections) and global revisions (corrections on the development, organization or style of a text) were made in their final texts. The students' perceptions towards text improvement in this web‐based peer review of modelling, coaching, scaffolding, articulation, reflection and exploration are also discussed in this study.     

Testing and ideology: policy debates about literacy assessments for Colorado’s bilingual students

ABSTRACT

The Colorado Reading to Ensure Academic Development Act requires grade-level attainment in literacy in English for students in grades K-3. Its practical outcome, however, has been to pressure schools with bilingual programs to shift their instructional language allocations towards more English in the early grades. Proposed rule revisions debated by the state Board of Education sought to facilitate testing in students’ language of instruction for those in bilingual programs. Analysis of written and verbal opposition to the proposed rule revisions demonstrates the persistence of insidious ethnoculturalist discourses opposing bilingual education as well as the cooptation of liberal multiculturalist discourses that, while framing bilingualism as an asset, argue that it is underdeveloped in bilingual programs that do not include English instruction from the outset. Given that bilingual instruction has demonstrated time and again that it benefits students acquiring English in schools, such new discursive turns pose a threat that must be recognized to fend off further legislative and regulatory attempts against bilingual education.     

Charting the routes to revision: An interplay of writing goals,peer comments,and self-reflections from peer reviews

Building upon self-regulated learning theories, we examined the nature of student writing goals and the relationship of these writing goals to revision alone and in combination with two other important sources of students’ self-regulated revision—peer comments on their writing, and reflections for their own writing obtained from reviewing others’ writing. Data were obtained from a large introductory undergraduate class in the context of two 1000-word writing assignments involving online peer review and a required revision. We began with an investigation of students’ free response learning goals and a follow-up quantitative survey about the nature and structure of these writing goals. We found that: (a) students tended to create high-level substantive goals more often, (b) students change their writing goals across papers even for a very similar assignment, and (c) their writing goals divide into three dimensions: general writing goals, genre writing goals, and assignment goals. We then closely coded and analyzed the relative levels of association of revision changes with writing goals, peer comments, reflections from peer review, and combinations of these sources. Findings suggest that high-level revisions are commonly associated with writing goals, are especially likely to occur for combinations of the three sources, and peer comments alone appeared to make the largest contributions to revision.     

‘They might know a lot of things that I don’t know’: investigating differences in preservice teachers’ ideas about contextualizing science instruction in multilingual classrooms

This paper describes the results from a qualitative study of 72 preservice teachers’ initial ideas about contextualizing science instruction with language minority students. Participants drew primarily on local ecological and multicultural contexts as resources for contextualizing instruction. However, preservice teachers enrolled in the bilingual certification program articulated more asset-oriented and less stereotypical ideas than those not seeking bilingual certification. Results can inform teacher education programs that aim to prepare graduates for teaching science in multilingual classrooms.

Students’ Perceptions of Code-Switching in Natural Sciences Classrooms: A South African Perspective

Although South Africa is a multilingual country with 11 official languages, English dominates as the language of teaching and instruction in almost all schools. In addition to this, the Natural Sciences teachers at the school of study were cautioned not to use code-switching because the school policy states that the medium of instruction should be exclusively English. Recently, students at this school complained about teachers who had been code-switching between one or more indigenous languages and English. The objectives of this investigation, therefore, were to explore the perceptions of Grade 8 students regarding code-switching in Natural Sciences classrooms, their perceptions of the effect of code-switching on their academic achievement and also how the use of this teaching strategy influenced their respect for their teacher. Data were collected by means of a questionnaire and the findings revealed that students believed that the use of code-switching confused many students, resulting in underachievement in Natural Sciences and that they respected teachers more when they taught in English only.     

English-Plus Multilingualism as the New Linguistic Capital? Implications of University Students’ Attitudes Towards Languages of Instruction in a Multilingual Environment

This article investigates university students’ attitudes and perceptions about language in a multilingual country where most instruction is in English and annual national literacy results have been declining for at least 15 years. Despite this decline, English seems to be entrenched as the language of instruction, and at university it seems a foregone conclusion that instruction will occur in English. Bourdieu’s concept of linguistic capital is offered as an explanation for the preponderance of English, but the question is posed: Is the dominance of English as simple as desiring linguistic capital? Do students really regard English as critical to success, and if so, is it to the exclusion of their home languages? The results show that students invest considerable effort in learning English, but not to the exclusion of their home language and with little desire to assimilate with the English culture. The results also provide interesting and sometimes contrasting insights into students’ desired language of instruction.

Peer-feedback and revision process in a wiki mediated collaborative writing

This study investigated the use of a wiki for collaborative writing among primary levels five (P5) and six (P6) students (n = 119) in a Chinese primary school in Hong Kong where English is taught as a second language (L2). Three classes of students and their English subject teachers participated in a three-month English language writing programme using a wiki. Quantitative and qualitative data were analyzed from activities recorded in the wiki system, including posted edits and comments, students’ group writings and student and teacher interviews. The wiki page history revealed information on the types of revisions that occurred, showing that different types of feedback elicited actual revisions, which may have resulted in better group writing. Findings from the study may shed light on how wikis can help provide support for students’ collaborative writing process with wikis, and how peer-feedback can influence this process.     

Spelling and grammar checkers: are they intrusive?

Spelling and grammar checkers help to make surface errors more apparent; do they influence the way in which people revise the content of their writing? We investigated whether the presence of checkers distracts students from making content revisions. Twenty‐five freshmen, 20 English majors and 20 graduate students revised two essays on a computer, one with the spelling and grammar checkers, and the other with a dictionary. These essays were unfamiliar to the students and rigged with content and surface errors. The checkers helped the participants to revise text for surface features but did not affect the students’ other revisions. Our findings suggest that checkers are helpful yet do not inhibit students’ ability to make content revisions.     

Tutoring the end-of-studies dissertation: helping psychology students find their academic voice when revising academic texts

This intervention study aimed at helping undergraduate students of psychology learn to use the discursive resources useful to make academic voice visible in their texts and to improve their writing practices. The intervention involved tutorial meetings and collaborative revisions in two different learning environments, on-line and face-to face. The final text quality, the students’ knowledge and the amount and the quality of revisions were assessed in both conditions. Results show that the quality of the texts improved for both intervention groups in contrast with for control group, and better texts were related with higher rates of revision and more students’ satisfaction with the intervention.     

Facilitating conceptual change in ninth grade students’ understanding of human circulatory system concepts

The purpose of this study was to investigate the effectiveness of the conceptual change text oriented instruction over traditionally designed instruction on ninth grade students’ understanding of the human circulatory system concepts, and their retention of this understanding. The subjects of this study consist of 73 ninth grade female students from two classes of a basic school in Jordan. One of the classes was randomly assigned as an experimental group in which conceptual change text oriented instruction was implemented, and the other class was randomly assigned as a control group in which students were instructed by traditionally designed biology instruction. Results showed that students exposed to conceptual change oriented instruction had better understanding of the human circulatory system concepts than those exposed to traditional instruction. The results also showed that the conceptual change text oriented instruction was significantly better than the traditional instruction in retention of this understanding.     

L1-assisted reciprocal teaching to improve ESL students’ comprehension of English expository text

A multiple-baseline design across three schools was used to investigate the effects of L1-assisted reciprocal teaching on 12 Year 7 and Year 8 (Grades 6 and 7) Taiwanese ESL students’ comprehension of English expository text. The intervention comprised the alternate use of L1 (Mandarin) and L2 (English) reciprocal teaching procedures. Through 15–20 days of instruction, students learned how to foster and monitor their comprehension by using the cognitive and metacognitive strategies of questioning, summarising, clarifying, and predicting. Students made gains on both researcher-developed and standardised tests of reading comprehension and showed evidence of qualitative changes in their comprehension processes when reading L1 and L2 texts.     

Effect of screen size on multimedia vocabulary learning

The objective of this study was to investigate the effects of three different screen sizes (small, medium and large) and two types of multimedia instruction (text only and text with pictorial annotation) on vocabulary learning. One hundred thirty‐five Korean middle school students learning English as a foreign language were randomly distributed into six groups and were given a pretest, a self‐study multimedia instruction, a posttest and a retention test online. The pretest, posttest and retention test were identical and included 30 vocabulary questions. Results show that the large screen multimedia instruction helped the students to learn English vocabulary more effectively than the small screen instruction as demonstrated on both the posttest and retention test. However, there was little difference in vocabulary learning between the text‐only and text‐with‐pictorial annotation instructions. Although visual perception can be influenced by each learner's expectations and knowledge, using a smaller screen for instruction causes more challenges for learners to perceive and comprehend vocabulary learning.     

Effectiveness of Explicit Phonological‐Awareness Instruction for At‐Risk English Learners

This article examines the effects of intensive phonological‐awareness (PA) instruction for kindergarten English learners. One intact kindergarten class was provided 300 minutes of intensive instruction in PA. Results indicate that students who received intervention made significant growth in word reading when compared to a cohort of kindergarten students who received general kindergarten instruction. The article also discusses ability‐group differences in performance among high‐, middle‐, and low‐performing students and the implications of these findings for instructional practice.     

Investigating the impact of automated feedback on students’ scientific argumentation

ABSTRACT

This study investigates the role of automated scoring and feedback in supporting students’ construction of written scientific arguments while learning about factors that affect climate change in the classroom. The automated scoring and feedback technology was integrated into an online module. Students’ written scientific argumentation occurred when they responded to structured argumentation prompts. After submitting the open-ended responses, students received scores generated by a scoring engine and written feedback associated with the scores in real-time. Using the log data that recorded argumentation scores as well as argument submission and revisions activities, we answer three research questions. First, how students behaved after receiving the feedback; second, whether and how students’ revisions improved their argumentation scores; and third, did item difficulties shift with the availability of the automated feedback. Results showed that the majority of students (77%) made revisions after receiving the feedback, and students with higher initial scores were more likely to revise their responses. Students who revised had significantly higher final scores than those who did not, and each revision was associated with an average increase of 0.55 on the final scores. Analysis on item difficulty shifts showed that written scientific argumentation became easier after students used the automated feedback.     

The influence of concept mapping on achievement,self-regulation,and self-efficacy in students of English as a second language

This study investigated the effectiveness of concept mapping used as a learning strategy with students in English as a Second Language classrooms. Seventy-nine ESL students participated in the study. Variables of interest were students’ achievement when learning from English-language text, students’ reported use of self-regulation strategies (self-monitoring and knowledge acquisition strategies), and students’ self-efficacy for learning from English-language text. A randomized pre-test–post-test control group design was employed. The findings showed a statistically significant interaction of time, method of instruction, and level of English proficiency for self-monitoring, self-efficacy, and achievement. For all four outcome variables, the concept mapping group showed significantly greater gains from pre-test to post-test than the individual study group. The findings have implications for both practice and research.
