学习方式的变革:提取促进学习

提取练习效应是指在学习与最终测验之间,等长时间的提取练习与重复学习相比,前者更能促进长时记忆的保持,也称为测试效应。大量研究表明提取测试是一种高效的学习策略,师生却对此认识不足,认为测试只是检测学习效果的评估工具,并不能改变或促进学习。本文主要从提取练习促进学习的认知神经加工机制、提取练习在实践应用中的特点、提高提取练习效应的方法及其在教学实践中的局限四方面梳理了相关研究,为提取练习广泛应用于教学实践提供支持,同时也为师生正确高效利用这一策略提供了参考,使学生获得更高效和持久的学习。     

Is expanding retrieval a superior method for learning text materials?

Expanding retrieval practice refers to the idea that gradually increasing the spacing interval between repeated tests ought to promote optimal long-term retention. Belief in the superiority of this technique is widespread, but empirical support is scarce. In addition, virtually all research on expanding retrieval has examined the learning of word pairs in paired-associate tasks. We report two experiments in which we examined the learning of text materials with expanding and equally spaced retrieval practice schedules. Subjects studied brief texts and recalled them in an initial learning phase. We manipulated the spacing of the repeated recall tests and examined final recall 1 week later. Overall we found that (1) repeated testing enhanced retention more than did taking a single test, (2) testing with feedback (restudying the passages) produced better retention than testing without feedback, but most importantly (3) there were no differences between expanding and equally spaced schedules of retrieval practice. Repeated retrieval enhanced long-term retention, but how the repeated tests were spaced did not matter.     

Classroom-based programs of retrieval practice reduce middle school and high school students’ test anxiety

When retrieval practice is applied in classroom settings, do K-12 students experience changes in test anxiety? To answer this question frequently asked by educators, we surveyed 1408 middle school and high school students about their study strategy preferences and their reactions to a classroom-based program of retrieval practice. For classes in which retrieval practice occurred, 92% of students reported that retrieval practice helped them learn and 72% reported that retrieval practice made them less nervous for unit tests and exams. This study is the first to examine the relationship between retrieval practice and classroom test anxiety, and self-reported study strategy use in pre-college students. In light of our results, we encourage K-12 teachers to use retrieval practice in their classrooms to reduce test anxiety and improve learning.     

The learning benefits of teaching: A retrieval practice hypothesis

Teaching educational materials to others enhances the teacher's own learning of those to‐be‐taught materials, although the underlying mechanisms remain largely unknown. Here, we show that the learning‐by‐teaching benefit is possibly a retrieval benefit. Learners (a) solved arithmetic problems (i.e., they neither taught nor retrieved; control group), (b) taught without relying on teaching notes (i.e., they had to retrieve the materials while teaching; teaching group), (c) taught with teaching notes (i.e., they did not retrieve the materials while teaching; teaching without retrieval practice [TnRP] group), or (d) retrieved (i.e., they did not teach but only practised retrieving; retrieval practice group). In a final comprehension test 1 week later, learners in the teaching group, as did those in the retrieval practice group, outperformed learners in the TnRP and control groups. Retrieval practice possibly causes the learning benefits of teaching.     

Expanding retrieval practice: An effective aid to preschool children's learning

The benefits of expanding retrieval practice for preschool children were explored in two experiments. In Experiment 1, three groups learned names for six plush toy pigs using expanding retrieval practice, a reward incentive, or a control condition. Reward did not significantly improve learning but retrieval practice doubled recall. In Experiment 2, three groups learned names to soft toys, comparing recall following massed elaborative study with either expanding retrieval practice or expanding re-presentation. Recall was tested after 1 minute, 1 day, and 2 days. A very large effect size (d = 1.9) indicated the very considerable benefit from expanding retrieval practice over the elaboration condition. Comparison with the re-presentation condition suggested that half of the benefit of expanding retrieval practice came from spaced scheduling and half from retrieval practice. Expanding retrieval practice provides an effective method to improve learning by young children.     

Benefits from retrieval practice are greater for students with lower working memory capacity

We examined the effects of retrieval practice for students who varied in working memory capacity as a function of the lag between study of material and its initial test, whether or not feedback was given after the test, and the retention interval of the final test. We sought to determine whether a blend of these conditions exists that maximises benefits from retrieval practice for lower and higher working memory capacity students. College students learned general knowledge facts and then restudied the facts or were tested on them (with or without feedback) at lags of 0–9 intervening items. Final cued recall performance was better for tested items than for restudied items after both 10 minutes and 2 days, particularly for longer study–test lags. Furthermore, on the 2-day delayed test the benefits from retrieval practice with feedback were significantly greater for students with lower working memory capacity than for students with higher working memory capacity (r?=??.42). Retrieval practice may be an especially effective learning strategy for lower ability students.     

Multimedia learning trumps retrieval practice in psychology teaching

It is well established that studying with (vs. without) visual illustrations as well as taking tests (vs. restudying) is beneficial for learning, but on which strategy should one put the efforts, or should they be combined for best learning? Eighty‐eight upper secondary school students were given a brief lecture presented verbally (6 classes) or with the aid of a visual illustration (visuoverbal, 6 classes). The information was processed again by taking a memory test or by restudying. Recall and transfer tests were conducted after some few minutes and again after one week. The visuoverbal lecture resulted in better learning than verbal presentation only. A significant study strategy by retention interval interaction was found. However, this interaction was not qualified by a testing effect. Hence, taking tests (retrieval practice) did not lead to better learning than restudying. It was concluded that it is worthwhile to use visual illustrations in teaching. However, the present study did not reveal any synergistic effects from the combination of visuoverbal presentation and retrieval practice.     

The Effect of Retrieval Practice in Primary School Vocabulary Learning

The testing effect refers to the finding that retrieval practice leads to better long‐term retention than additional study of course material. In the present study, we examined whether this finding generalizes to primary school vocabulary learning. We also manipulated the word learning context. Children were introduced to 20 words by listening to a story in which novel words were embedded (story condition) or by listening to isolated words (word pairs condition). The children practised the meaning of 10 words by retrieval practice and 10 words by restudy. After 1 week, they completed a cued recall test and a multiple choice test. Words learned by retrieval practice were recalled better than words learned by additional study, but there was no difference in recognition. Furthermore, the children in the word pairs condition outperformed the children in the story condition. These results show that retrieval practice may improve vocabulary learning in children.

Strengthening concept learning by repeated testing

The aim of this study was to examine whether repeated testing with feedback benefits learning compared to rereading of introductory psychology key‐concepts in an educational context. The testing effect was examined immediately after practice, after 18 days, and at a five‐week delay in a sample of undergraduate students (n = 83). The results revealed that repeated testing with feedback significantly enhanced learning compared to rereading at all delays, demonstrating that repeated retrieval enhances retention compared to repeated encoding in the short‐ and the long‐term. In addition, the effect of repeated testing was beneficial for students irrespectively of working memory capacity. It is argued that teaching methods involving repeated retrieval are important to consider by the educational system.     

The benefit of retrieval practice over elaborative restudy in primary school vocabulary learning

The testing effect is the phenomenon that retrieval practice of learning material after studying enhances long-term retention more than restudying. We examined retrieval practice in primary school vocabulary learning in two experiments. Nine-year-old children studied word definitions and completed exercises according to three learning conditions: pure restudy, elaborative restudy or retrieval practice. Children in the pure restudy condition reread and partly copied the definitions. In the elaborative restudy condition children reread the definitions and connected semantically related words to the target words. Children in the retrieval practice condition recalled the words based on their definitions. Overall, on the fill-in-the-blank test after one week children in the retrieval practice condition outperformed children in the other conditions, but on the multiple-choice test there were no differences. Retrieval practice may be effective for primary school vocabulary learning, but there is uncertainty about the practical value and the magnitude of the retrieval practice effect.     

Does Providing Prompts During Retrieval Practice Improve Learning?

The purpose of this investigation was to identify ways to prompt retrieval practice to make recall even more effective at producing meaningful learning. In two experiments, subjects read educational texts and practiced retrieval across two periods. During prompted retrieval, subjects were cued to explain and describe concepts from the text, whereas during free recall, subjects recalled as much of the material from the text as they could. A reading control condition was also included. Learning was assessed using both verbatim and higher‐order questions 1 week later. Practicing retrieval improved learning relative to the control on both types of questions; however, whether subjects practiced free or prompted retrieval did not matter for learning. Subjects rated prompted retrieval as less enjoyable and interesting than the other retrieval conditions. Results demonstrate practicing retrieval promoted meaningful learning, and that subjects' initial retrieval success was highest when they used their own retrieval strategies during recall.

Retrieval-based learning: The need for guided retrieval in elementary school children

Three experiments were aimed at adapting retrieval practice techniques that are effective with college students to work with elementary school children. Children participated in their classrooms and completed activities with educational texts selected from the school curriculum. In Experiment 1, when children were asked to freely recall the texts, they recalled very little of the material (about 10%) and showed almost no improvement after rereading. In another condition that involved creating concept maps, the children produced only about 20% of the ideas on their maps, even though they viewed the texts during the entire activity. Experiments 2 and 3 explored ways to provide support during retrieval activities. In Experiment 2, children were very successful at retrieving knowledge on concept maps that were partially completed. In Experiment 3, a question map activity, where questions were displayed in a relational map format, was effective for guiding retrieval practice and improving learning relative to repeated studying. The results demonstrate the importance of examining strategies that work with college students with young children in educational settings using authentic materials. The results also highlight the need for guided retrieval practice in young children.

Does testing with feedback help grade-school children learn key concepts in science?

Testing effects have been well-established across a variety of studies involving school-age children. Specifically, children's test performance improves when they are given the opportunity to practice retrieval prior to the final test as compared to when practice involves only study. The current investigation focused on the influence of testing with feedback on fifth graders’ learning of science concepts. Across two experiments, 65 students studied twenty key concept definitions. After study, the definitions were randomly assigned to one of four conditions: control, test only, study only, and test plus feedback. Concepts assigned to the latter three conditions were presented again (either for test only, study only, or test plus feedback) during two separate sessions, and a final test was administered during a separate session. At the final test, students were asked to provide the definition for each of the twenty key concepts. Final test performance was best for definitions that had been tested with feedback, followed by recall for those that had only been tested or only restudied, with lowest performance for those that did not receive additional practice. Despite multiple sessions spaced across several days, however, performance for all conditions was low, which may have resulted from the ineffective use of feedback. In summary, testing followed by feedback can boost younger students learning of science concepts, but mastery will require the use of other strategies as well.     

Expanding retrieval practice promotes short-term retention, but equally spaced retrieval enhances long-term retention

Expanding retrieval practice (T. K. Landauer & R. A. Bjork, 1978) is regarded as a superior technique for promoting long-term retention relative to equally spaced retrieval practice. In Experiments 1 and 2, the authors found that expanding retrieval practice of vocabulary word pairs produced short-term benefits 10 min after learning, conceptually replicating Landauer and Bjork's results. However, equally spaced retrieval produced superior retention 2 days later. This pattern occurred both with and without feedback after test trials. In Experiment 3, the 1st test occurred immediately or after a brief delay, and repeated tests were expanding or equally spaced. Delaying the first test improved long-term retention, regardless of how the repeated tests were spaced. The important factor for promoting long-term retention is delaying initial retrieval to make it more difficult, as is done in equally spaced retrieval but not in expanding retrieval. Expanding the interval between repeated tests had little effect on long-term retention in 3 experiments.     

Using principles of cognitive science to improve science learning in middle school: What works when and for whom?

Four principles of cognitive science were used to make systematic revisions in middle school science instructional modules from two kinds of curriculum: one popular textbook series and one popular hands‐on series (two modules each). Schools were randomly assigned to 1 of the 3 arms (cognitive science modifications with professional development, active control with professional development, or business‐as‐usual). Two cohorts of students were followed in each arm for each setting. There were significant benefits of the cognitive science intervention, but the nature of effects varied for the two settings and curricula. For the text‐based curriculum, positive effects of cognitive science modifications were concentrated in classrooms with lower proportions of underrepresented minority students. For the hands‐on curriculum, there were positive effects that were not linked to school composition. Participation in the active control did not significantly improve student learning. Implications for policy and research are discussed.     

线索强度:检验提取练习效应内部机制的重要变量

研究采用提取练习效应研究的经典范式,通过比较学习材料的线索强度对不同学习策略效果的影响来探讨提取练习效应的内部机制。结果发现：（1）当最终测试为线索回忆时,线索强度与学习策略交互作用显著,强线索条件下两组成绩差异不显著,弱线索条件下提取练习组显著高于精细加工组;（2）当最终测试为再认测验时,线索强度与学习策略在虚报率和目标词再认反应时上交互作用显著,精细加工组在弱线索条件下的虚报率显著高于强线索条件,在强弱线索条件下的目标词再认反应时差异不显著;提取练习条件组在强弱线索条件下的虚报率差异不显著,在强弱线索条件下的目标词再认反应时差异边缘显著,弱线索条件下反应时要比强线索条件下更长。上述结果表明材料的线索强度是区分提取练习与精细加工的重要变量,揭示了提取练习的内部加工机制不同于精细加工,反驳了精细提取假设,支持情景语境假设。     

Assessing students' use of optional online lecture reviews

Online practice quizzes can be used to supplement instruction in the classroom. Such quizzes can engage retrieval practice, thereby improving learning and retention. However, despite their potential benefits, recent work suggests that students typically underutilize online practice quizzes. This article reports an observational classroom study, in which students were provided optional online reviews throughout the semester. The reviews could be accessed in test format, in which students were given multiple-choice questions and provided correct answer feedback, or in read format in which students were given the same questions and were shown the correct answers. Students who used the test format performed better on exams than students who used the read format or did not use the reviews. Nevertheless, the massive majority of the online reviews (approximately 88%) were not completed, highlighting the tendency for students to underutilize optional online reviews.     

Divided attention: An undesirable difficulty in memory retention

How can we improve memory retention? A large body of research has suggested that difficulty encountered during learning, such as when practice sessions are distributed rather than massed, can enhance later memory performance (see R. A. Bjork & E. L. Bjork, 1992). Here, we investigated whether divided attention during retrieval practice can also constitute a desirable difficulty. Following two initial study phases and one test phase with Swahili–English word pairs (e.g., vuvi–snake), we manipulated whether items were tested again under full or divided attention. Two days later, participants were brought back for a final cued-recall test (e.g., vuvi–?). Across three experiments (combined N = 122), we found no evidence that dividing attention while practicing retrieval enhances memory retention. This finding raises the question of why many types of difficulty during practice do improve long-term retention, but dividing attention does not.
