Vocabulary knowledge is one of the most important elements of reading comprehension. Text coverage is the proportion of known words in a given text. We hypothesize that text comprehension increases exponentially with text coverage due to network effects and activation of prior knowledge. In addition, the lexical threshold hypothesis states that…

This study aims to scrutinize the effects of gamified Turkish vocabulary teaching on vocabulary development, and motivation on learning words. A nested mixed-method experimental design (gamification-based vocabulary learning for the experimental group instructor-led vocabulary learning for the control group) and was conducted with 34 fourth-grade…

A solid understanding of fractions is the cornerstone for acquiring proficiency with rational numbers and paves the way for learning advanced mathematical concepts, such as algebra. Fraction difficulties limit not only students' educational and vocational opportunities but also their ability to solve everyday problems. Students who exit 6th grade…

This research aims to improve the vocabulary knowledge of Thai EFL students by using audio-visual aids as instructional tools. Hopefully, this study serves as an initial foundation to develop students' vocabulary knowledge and benefit the pedagogical development in Thailand. Consequently, this research aimed to explore the effectiveness of…

The number of English Learners (EL) enrolled in general education classroom environments in Illinois is increasing. State assessment data demonstrates that EL students are academically behind in reading. Since general education teachers in Illinois are not required to have an ESL endorsement and teacher preparation programs do not consistently…

District leaders in a large urban school district in central Florida wanted to test the efficacy of a new curriculum designed to enhance the word knowledge of grade 5 students so as to improve reading achievement. The new curriculum, called Word Knowledge Instruction (WKI), consists of 15-minute lessons taught 4 days a week for 20 weeks. The…

This is the appendix for the report, "The Impact of Word Knowledge Instruction on Literacy Outcomes in Grade 5." District leaders in a large urban school district in central Florida wanted to examine the efficacy of a new curriculum designed to enhance the word knowledge of grade 5 students so as to improve reading achievement. The new…

Reading and writing have an essential place in the social life of individuals as well as in school learning. In this study, bidirectional relationships between reading and writing skills have been examined after gender and socio-economic level of students have been controlled. The participants in this study were 240 fifth-grade students from 10…

Background: Reading comprehension is a complex process influenced by many factors. However, the abilities that are known to influence reading comprehension may not contribute equally for children with different levels of oral language. Aims: Here we examined the relationship of two factors known to influence reading comprehension (morphology and…

This study seeks to contribute to the small, but growing area of research regarding technology potential in the field of vocabulary research. The study aims to determine the usefulness of augmented reality (AR) technology in EFL vocabulary learning. An experiment was conducted to examine young learners' motivation and vocabulary retention. The…

The purposes of this study were to: (1) build an appropriate model for predicting primary schoolchildren's English vocabulary knowledge; (2) examine whether the developed model applies to new data; and (3) discuss how to apply the model to L2 vocabulary instruction. More specifically, the study asked third- and fourth-grade public primary school…

This experimental study examines the role of oral and written repetition strategies in consolidating new vocabulary in the classroom context. The participants in this study were divided into three treatment groups: oral, written and oral+written. A pretest and three delayed post-tests given at one day, one week and six weeks intervals were…

Purpose: Elementary-age dual language learners (DLLs) from Spanish-speaking homes in the United States are often characterized as at risk for low vocabulary in both Spanish and English. This longitudinal study examined conceptually scored receptive and expressive vocabulary development among DLLs from Spanish-speaking, low-income homes and…

We show how the novel use of a semantic representation based on Osgood's semantic differential scales can lead to effective features in predicting short- and long-term learning in students using a vocabulary learning system. Previous studies in students' intermediate knowledge states during vocabulary acquisition did not provide much information…

As the foundation of English, the vocabulary difficulty should be removed first with effective instructions to develop learners' English ability in order to meet the request of Thailand's national curriculum. In addition, because English is used as a medium of intercultural communication and one component of language learning, diverse cultural…
