Hu and Nation's (2000) study, which stipulated that second language (L2) readers need to be familiar with 98% of lexical items for adequate text comprehension, has become highly influential in L2 vocabulary research and pedagogy. However, the 98% critical threshold figure is based on findings from a research project in which a regression analysis…

Lexical ability, an umbrella term to cover various knowledge and skills pertaining to words in print, is a key component in reading comprehension. Little is known how different facets of lexical ability jointly contribute to L2 reading comprehension and how the contributions may differ between higher- and lower-proficiency L2 learners. This study,…

Underdeveloped reading comprehension skills can limit academic success; a particular challenge for English language learners (ELLs). The current study investigated whether a web-based text structure strategy, delivered via the Intelligent Tutoring of Structure Strategy (ITSS) program to adult Chinese ELLs, improved students' use of reading…

A common goal of Intelligent Tutoring Systems (ITS) is to provide learning environments that adapt to the varying abilities and characteristics of users. This type of adaptivity is possible only if the ITS has information that characterizes the learning behaviors of its users and can adjust its pedagogy accordingly. This study investigated an…

Twenty adult ESL students at a community college participated in a semester reading intervention. Participants received a modified extensive reading treatment, and some participants received an additional repeated reading direct instruction reading intervention. The author examined the impact of the reading interventions on ESL students' reading…

This paper describes a new automated disengagement tracking system (DTS) that detects learners' maladaptive behaviors, e.g. mind-wandering and impetuous responding, in an intelligent tutoring system (ITS), called AutoTutor. AutoTutor is a conversation-based intelligent tutoring system designed to help adult literacy learners improve their reading…

Many students with reading difficulties and disabilities (RD) also have Attention Deficit/Hyperactivity Disorder (ADHD). This randomized clinical trial compared the effects of ADHD treatment alone (medication, parent training), intensive reading intervention alone, and their combination on the reading fluency and comprehension of students with…

Providing glosses that explain the meanings of unknown words is a common method of promoting learners' learning of new words. Numerous studies have shown that compared with no-gloss condition, glosses benefit the learning of the meaning of new words. This study combines both online (i.e., eye-tracking) and offline (i.e., immediate vocabulary…

Inferencing skills uniquely contribute to the reading comprehension skills of older grade-school and college students. Evidence also suggests that children's reading component skills, such as decoding and language comprehension, differentially contribute to various reading comprehension assessments. However, additional research is needed to…

This research compared the contributions of lexical inferencing, decoding, and listening comprehension to reading comprehension in Chinese-speaking learners of English as a second language (ESL) enrolled in university bridging programs in the U.S. and Chinese-speaking university learners of English as a foreign language (EFL) in mainland China.…

Selecting assessments for adults who struggle with reading can be difficult because few literacy measures used by reading researchers have been normed on this population, leaving uncertainty regarding the validity of these tests for adult learners. This study focused on the performance of 116 adults reading between the 3rd and 8th grade levels on…

In recent years attention has been accorded to language learners' affective factors and learning styles. Two of the significant learning styles are impulsivity and reflectivity which have not been studied as much as other styles such as introversion and extroversion. This study endeavored to find out whether or not impulsivity and reflectivity…

The purpose of this study was to evaluate the efficacy of the Home Instruction for Parents of Preschool Youngsters program when implemented within Head Start programs by measuring children's language proficiency scores. Participants were kindergarteners concurrently enrolled in both a Head Start program and the Home Instruction for Parents of…

The current study was conducted to investigate the effect of task-based and topic-based speaking activities on improving the speaking ability among Iranian EFL learners. The study used quasi-experimental design. The subjects consisted of 60 male and female students who were selected from among 90 EFL learners by applying the nelson proficiency…

Besides work-oriented training, most Dutch adult learning courses of formal and non-formal education focus on three basic skills: literacy, numeracy and problem solving in technology-rich environments. In the Netherlands, the Ministry of Education, Culture and Science recently initiated the development of a new adult education framework concerning…
