Spacing extinction trials alleviates renewal and spontaneous recovery

Studies of extinction in classical conditioning situations can reveal techniques that maximize the effectiveness of exposure-based behavior therapies. In three experiments, we investigated the effect of varying the intertrial interval during an extinction treatment in a fear-conditioning preparation with rats as subjects. In Experiment 1, we found less fear at test (i.e., more effective extinction) when extinction trials were widely spaced, relative to intermediate or massed extinction trials. In Experiment 2, we used an ABA renewal procedure and observed that spaced trials attenuated renewal of conditioned fear relative to massed trials. In Experiment 3, we used a similar design, but instead of changing the physical context at the time of testing, we interposed a retention interval after the extinction treatment to produce a change in the temporal context. The results showed less spontaneous recovery of fear after spaced than after massed extinction trials. These results suggest that extinction is more enduring when the extinction trials are spaced rather than massed. Although the benefits of spacing trials are small when there is no contextual change from extinction to testing, a change in either physical or temporal context following massed extinction trials leads to a recovery from extinction, which is reduced when the trials are spaced.     

EXAMINING THE USE OF SPACING EFFECT TO INCREASE THE EFFICIENCY OF INCREMENTAL REHEARSAL

Incremental rehearsal (IR) is a highly effective intervention that uses high repetition and a high ratio of known to unknown items with linearly spaced known items between the new items. It has been hypothesized that narrowly spaced practice would result in quick learning, whereas items that are widely spaced would result in longer‐term retention. The current study examined the effect of spacing by teaching vocabulary words to 36 fourth‐grade students. Each student was randomly assigned to a widely spaced IR condition (i.e., one unknown item, one known item, one unknown item, two known items, one unknown item, three known items, and an increase in the number of known items presented each time by one) or an IR condition in which spacing increased exponentially (IR‐Exp; i.e., one unknown item, one known item, one unknown item, two known items, one unknown item, four known items, and one unknown item, eight known items). The results indicated that the students in the study retained twice as much information with the widely spaced IR than with the IR‐Exp condition, but the latter required half as much time. IR and IR‐Exp were equally efficient, but IR continues to be superior to all other flashcard approaches in improving retention.     

The Vocabulary Reality from Elementary School to High School in China

The purpose of this research is to examine how large English language vocabulary is used in elementary,middle and high schools in China in order to plan for teaching how much English vocabulary college students learn in the first two years to develop general English ability.One corpus is used to examine how many high-frequency words are included in elementary,middle and high school English vocabulary and Vocabprofile and Text Lex Compare of on-line tool-http://www.lextutor.ca/are used to.There are three interesting points arising from the analysis of the three word lists.First,most of the words consisted of basic-level words.Second,from analysis of the degrees of word repetition,students only learn 2208 new words and there are1812 repeated words in the three stages.Third,from analysis of how much coverage of the three vocabulary families each of the three base lists provide,99.9%of the running words are in base word list one,two and three.Based on these viewpoints,basic words should be identified scientifically and educationally for Chinese learners of English.     

Using Spacing to Enhance Diverse Forms of Learning: Review of Recent Research and Implications for Instruction

Every day, students and instructors are faced with the decision of when to study information. The timing of study, and how it affects memory retention, has been explored for many years in research on human learning. This research has shown that performance on final tests of learning is improved if multiple study sessions are separated—i.e., “spaced” apart—in time rather than massed in immediate succession. In this article, we review research findings of the types of learning that benefit from spaced study, demonstrations of these benefits in educational settings, and recent research on the time intervals during which spaced study should occur in order to maximize memory retention. We conclude with a list of recommendations on how spacing might be incorporated into everyday instruction.     

Exploring the feasibility of a classroom‐based vocabulary intervention for mainstream secondary school students with language disorder

Vocabulary knowledge has been shown to be a predictor of academic success, posing a challenge for children and young people with language disorder. Language disorder can persist into adolescence and yet there is limited evidence on how to support the vocabulary skills of adolescents with language disorder in a mainstream setting. This article describes an experimental study aimed at investigating the feasibility of a whole‐class approach to increase the understanding and use of curriculum vocabulary in adolescents with language disorder. Ten curriculum words were taught by the science teacher using a phonological‐semantic approach, and 10 matched same‐topic words were taught using routine teaching practice. Progress was made post‐intervention in word knowledge of both low‐frequency experimental and control words, with significantly greater change in knowledge of the experimental words. Most students, and the teacher, viewed the phonological‐semantic word‐learning approach favourably.     

Effects of a Supplemental Vocabulary Intervention on the Word Knowledge of Kindergarten Students At Risk for Language and Literacy Difficulties

The purpose of this study was to examine the effectiveness of a vocabulary intervention designed to supplement research‐based classroom vocabulary instruction, implemented with students who may be at risk for language and learning difficulties. Participants included 43 kindergarten students who received research‐based classroom vocabulary instruction. Students with the 20 lowest scores on the Peabody Picture Vocabulary Test‐III administered at pretest received additional small‐group supplemental vocabulary intervention. Results of within‐subjects comparisons indicated that, overall, at‐risk students made greater gains in word knowledge on target words that received the supplemental intervention as compared to words that received only classroom‐based instruction. In addition, at‐risk students who received the supplemental intervention demonstrated word‐learning gains that approached those of their peers who received classroom instruction alone. Implications along with limitations of the current study and directions for future research are discussed.     

Extending Cognitive Load Theory to Incorporate Working Memory Resource Depletion: Evidence from the Spacing Effect

Depletion of limited working memory resources may occur following extensive mental effort resulting in decreased performance compared to conditions requiring less extensive mental effort. This “depletion effect” can be incorporated into cognitive load theory that is concerned with using the properties of human cognitive architecture, especially working memory, when designing instruction. Two experiments were carried out on the spacing effect that occurs when learning that is spaced by temporal gaps between learning episodes is superior to identical, massed learning with no gaps between learning episodes. Using primary school students learning mathematics, it was found that students obtained lower scores on a working memory capacity test (Experiments 1 and 2) and higher ratings of cognitive load (Experiment 2) after massed than after spaced practice. The reduction in working memory capacity may be attributed to working memory resource depletion following the relatively prolonged mental effort associated with massed compared to spaced practice. An expansion of cognitive load theory to incorporate working memory resource depletion along with instructional design implications, including the spacing effect, is discussed.     

Effects of a Supplemental Vocabulary Program on Word Knowledge and Passage Comprehension

Abstract

A cluster randomized trial estimated the effects of a supplemental vocabulary program, Elements of Reading®: vocabulary on student vocabulary and passage comprehension in moderate- to high-poverty elementary schools. Forty-four schools participated over a period spanning 2 consecutive school years. At baseline, 1,057 teachers and 16,471 students from kindergarten, first, third, and fourth grade participated. The schools were randomly assigned to either the primary or intermediate grade treatment group. In each group, the nontreatment classrooms provided the control condition. Treatment classrooms used the intervention to supplement their core reading program, whereas control classrooms taught vocabulary business-as-usual. The intervention includes structured, weekly lesson plans for 6 to 8 literary words and aural/oral and written language activities providing multiple exposures and opportunity for use. Hierarchical linear modeling was used to estimate both proximal (Year 1) and distal (Year 2) effects on vocabulary and passage comprehension. The intervention had positive and statistically significant proximal effects but no statistically significant distal effects. The results indicate that the intervention can improve targeted vocabulary and local passage comprehension, but expecting global effects may be overly optimistic.     

Effects of GO FASTER on Morpheme Definition Fluency for High School Students with High‐Incidence Disabilities

Although vocabulary plays an important role in literacy and content instruction, there is a paucity of research identifying effective methods for teaching vocabulary. One promising strategy is morphemic analysis, which involves breaking words into morphemes, the smallest meaningful parts of words, and teaching students the meanings of those parts. The current study used a multiple probe across morphemes experimental design to determine the effects of an intervention package, GO FASTER (G raphic O rganizers; F lashcards A dded up and S elf‐graphed to T rack progress; E rrors R eviewed). Findings showed that with three to four instructional sessions, three high school students with high‐incidence disabilities successfully defined morphemes at a predetermined fluency rate and generalized these definitions to untaught words. Implications for practice and future research are discussed.     

Research Schools: Grounding Research in Educational Practice

ABSTRACT— Education lacks a strong infrastructure for connecting research with educational practice and policy. The need for this linkage grows as findings in cognitive science and biology become ever more relevant to education. Teachers often lack the background knowledge needed to interpret scientific results, whereas scientists often lack an understanding of pedagogical goals. We need to build an infrastructure that supports sustainable collaboration between researchers and teachers and creates a strong research foundation for education. A primary agent of the lasting collaboration between researchers and practitioners in medicine is the teaching hospital, where researchers and practitioners work together on research that is relevant to practice and the training of young professionals. Education needs analogous institutions—research schools—that join researchers and teachers in living, community‐based schools. In these schools, practice shapes research as much as research informs practice. Research schools will provide a fundamental infrastructure for linking transdisciplinary research on learning with educational policy and practice.     

Assessment must lead to action

Abstract

A new theory of the learning of reading, the Knowledge Sources Theory, has appeared in the research literature in the past ten years, and with an increasingly wide range of supporting evidence. A feature of the theory is the recognition of two ways of learning the relationships between letters and sounds within words. While both ways offer some facilitation of the learning of reading vocabulary, only one, lexicalised phonological recoding, is attuned to the total reading vocabulary of the child. The theory has prompted a revised understanding of some aspects of reading difficulties, including reading speed. For teaching practice, the theory has directed attention to the significance of the beginning reader's experience of both consistencies and inconsistencies of letter‐sound relationships in words, and to the ways in which the child's reading vocabulary knowledge is fostered and used in teaching letter‐sound relationships.     

Metacognition and the spacing effect: the role of repetition, feedback, and instruction on judgments of learning for massed and spaced rehearsal

Although memory performance benefits from the spacing of information at encoding, judgments of learning (JOLs) are often not sensitive to the benefits of spacing. The present research examines how practice, feedback, and instruction influence JOLs for spaced and massed items. In Experiment 1, in which JOLs were made after the presentation of each item and participants were given multiple study-test cycles, JOLs were strongly influenced by the repetition of the items, but there was little difference in JOLs for massed versus spaced items. A similar effect was shown in Experiments 2 and 3, in which participants scored their own recall performance and were given feedback, although participants did learn to assign higher JOLs to spaced items with task experience. In Experiment 4, after participants were given direct instruction about the benefits of spacing, they showed a greater difference for JOLs of spaced vs massed items, but their JOLs still underestimated their recall for spaced items. Although spacing effects are very robust and have important implications for memory and education, people often underestimate the benefits of spaced repetition when learning, possibly due to the reliance on processing fluency during study and attending to repetition, and not taking into account the beneficial aspects of study schedule.     

Effects of Contextual versus Definitional Computer‐assisted Vocabulary Instruction on Immediate and Long‐term Vocabulary Retention of Advanced ESL Students

This paper investigates the role of definitional information versus contextual information in computer‐assisted vocabulary instruction. A group of 58 advanced ESL students participated in the main data‐collection phase. The results revealed that context‐embedded vocabulary exercises facilitate better long‐term retention of words that exist in context. This finding is noteworthy in that the context‐embedded condition is the natural vocabulary condition commonly observed in reading. Students seldom encounter direct definitions or a series of related synonyms in the natural passage condition. Definitional knowledge, however, appears to be important in developing a basic concept of a given word in the initial phases of vocabulary development.     

Effects of individualized word retrieval in kindergarten vocabulary intervention

We examined the effects of adaptive word retrieval intervention on a classroom vocabulary program on children’s vocabulary acquisition in kindergarten. In the experimental condition, word retrieval was provided in a classroom vocabulary program, combining implicit and explicit vocabulary instructions. Children performed extra word retrieval activities and received semantic feedback for words they did not learn during the classroom vocabulary program. Eighty-seven children were in the experimental condition, and 115 children were in the classroom vocabulary control condition. Results showed the adaptive word retrieval intervention to stimulate higher learning gains than the classroom vocabulary program on the learning of the target words. Children in the experimental condition also showed transfer effects; they described more words on a standardized expressive vocabulary test than children in the control condition. The research findings suggest additional value of word retrieval with feedback for classroom vocabulary learning.

A Root Awakening: Vocabulary Instruction for Older Students with Reading Difficulties

There is reliable evidence that new vocabulary is primarily acquired through wide independent reading. However, struggling readers tend to avoid reading, resulting in limited word encounters and inadequate vocabulary growth, and they often have difficulties inferring the meanings of new words from context. While there are no clear solutions to the problem of vocabulary acquisition for older students with reading difficulties, there are instructional approaches that have some evidence of effectiveness for this population. We describe the research base and promising practices related to three aspects of vocabulary instruction: (1) creating a verbal learning environment that fosters word consciousness, (2) selecting and teaching specific words, and (3) teaching an independent word learning strategy through a combination of contextual and morphemic analysis. These instructional approaches are grounded in overarching principles recognized by researchers as being characteristic of effective instruction for students with learning difficulties, including explicit instruction, promoting cognitive and collaborative engagement, and providing many opportunities for practice, including distributed practice, with teacher feedback. Finally, we discuss the possibilities inherent in a cross‐content schoolwide approach to vocabulary instruction at the secondary level. We conclude with a call for additional research examining the effectiveness of instructional approaches to vocabulary development for secondary school students with reading difficulties, including a schoolwide collaborative model.

Enhancing Basal Vocabulary Instruction in Kindergarten

To enhance the basal vocabulary instruction for kindergarten students at risk for reading difficulties, lessons provided in typical curricular materials can be supplemented with instructional elements derived from research. This article addresses how teachers can add 15 minutes of higher order instructional activities to daily reading lessons to deepen students’ understanding of target vocabulary and offer multiple exposures to the words in different contexts. This enhanced basal vocabulary instruction model was field tested in two configurations of the kindergarten reading block to refine the procedures. These experiences provide insights into how the model can feasibly be implemented in small‐ or whole‐group formats to improve students’ learning and engagement.     

Distributed retrieval practice promotes superior recall of anatomy information

Effortful retrieval produces greater long‐term recall of information when compared to studying (i.e., reading), as do learning sessions that are distributed (i.e., spaced apart) when compared to those that are massed together. Although the retrieval and distributed practice effects are well‐established in the cognitive science literature, no studies have examined their additive effect with regard to learning anatomy information. The aim of this study was to determine how the benefits of retrieval practice vary with massed versus distributed learning. Participants used the following strategies to learn sets of skeletal muscle anatomy: (1) studying on three different days over a seven day period (SSSS_7,2,0), (2) studying and retrieving on three different days over a seven day period (SRSR_7,2,0), (3) studying on two different days over a two day period (SSSSSS_2,0), (4) studying and retrieving on two separate days over a two day period (SRSRSR_2,0), and (5) studying and retrieving on one day (SRx6₀). All strategies consisted of 12 learning phases and lasted exactly 24 minutes. Muscle information retention was assessed via free recall and using repeated measures ANOVAs. A week after learning, the recall scores were 24.72 ± 3.12, 33.88 ± 3.48, 15.51 ± 2.48, 20.72 ± 2.94, and 12.86 ± 2.05 for the SSSS_7,2,0, SRSR_7,2,0, SSSSSS_2,0, STSTST_2,0, and SRx6₀ strategies, respectively. In conclusion, the distributed strategies produced significantly better recall than the massed strategies, the retrieval‐based strategies produced significantly better recall than the studying strategies, and the combination of distributed and retrieval practice generated the greatest recall of anatomy information.
