Investigating the testing effect: Retrieval as a characteristic of effective study strategies

Presently, the most common approach to examining the testing effect is using a free recall form of retrieval practice. In this experiment, we compared free recall to other retrieval-based study strategies including practice quizzing, test-generation, and keyword. We also examined the possible benefit of coupling these retrieval-based strategies with free recall. A total of 338 undergraduates were randomly assigned to one of the nine conditions: a repeated retrieval (study-test) learning condition paired with one of the four retrieval-based strategies, a single retrieval (study-study) learning condition paired with a retrieval-based strategy, or a rehearsal (study-study-study) condition. Following a 7-day delay, students completed a test assessing retention of information learned. There was a significant interaction between learning condition (repeated vs. single retrieval practice) and type of retrieval-based strategy. Free recall and practice quizzing were the most effective types of retrieval practice, and coupling testgeneration and practice quizzing with free recall led to significant benefits in performance.     

Localizing the development of ability differences in organized memory

Although it is well know that learning disabled children tend to perform more poorly than normally achieving children on most memory tasks, the basis of this poor performance remains unclear. Recently, evidence has been accumulating which suggests that disabled children have difficulty with the basic processes of storage and retrieval. The purpose of the present research was to investigate this hypothesis using a recently developed model of memory that provides a factoring procedure for measuring storage and retrieval processes. In particular, we were interested in localizing the source of the development of ability differences in organized recall in early (grade 2) and later (grade 6) elementary school. All of the 600 children who participated had measured IQs in the 97–107 range; however, the disabled students were at least 1 year behind in either reading or arithmetic but not both. All of the children learned a 16-item list that was either unrelated or categorized using either a free or cued recall procedure. The results indicated that while ability differences were present at storage and retrieval, differences tended to be larger at retrieval than at storage, on categorized rather than on uncategorized lists, and in the cued rather than in the free recall conditions. These results illustrate that the ability to execute purposive components of retrieval develops more slowly in disabled than in nondisabled children. Consequently, it is these processes that should be the primary target in remedial memory programs.     

Memory for everyday information in students with learning disabilities

This study compared students with and without learning disabilities (LD) on their recall of academic information and information encountered in the students' everyday lives. The academic recall measures included a sentence listening span test, a rhyming words working memory test, and a visual matrix working memory task. Students' cued recall of all the tasks was also measured. The everyday working memory tasks included a dance episode event recall test; a library procedure recall test; and recall tests of commonly found objects, such as a coin, a telephone, and a McDonald's sign. Compared to students without LD, students with LD performed poorly on both the academic recall tasks and the everyday recall tasks. These results support the notion that some students with LD may have working memory problems that affect their performance on tasks other than reading. The results of the cued recall showed that the availability of cues significantly decreased the ability group differences on many of the academic and everyday tasks. This result replicates prior research findings that students with LD do not use retrieval strategies effectively and that some students with LD may have a production deficiency that affects their retrieval of previously encoded information.     

The Effects of Text Familiarity and Cohesion on Retrieval of Information Learned from Text

This study examined the effects of familiarity of passage concepts and passage cohesion on retrieval of text information. In order to distinguish between comprehension and retrieval processes, subjects were equated on comprehension; therefore, any differences found could be attributed to differences in retrieval processes. The passages used varied on familiarity and cohesion, but syntax was held constant. Middle school students learned information in passages to an 85% correct criterion using a study-test procedure. The subjects were not told that they would be tested on the material. Two weeks later, they took a free recall test and reported their rehearsal of the passage information during the intervening time period. The results showed that although the original amount learned was equated, recall of propositions from passages with more familiar concepts was about 35% greater than the recall from passages with less familiar concepts. There were no significant differences due to cohesion or the interaction of cohesion and familiarity. The explanation presented is that familiarity stimulates elaboration of passage material and elaborations provide alternate retrieval pathways at recall. Educational implications are discussed.     

The effect of field dependence and outline condition on learning high- and low-structure information from a lecture

Sixty-eight college students participated in the current research investigating the effects of an outline on field-dependent and field-independent students' learning of structurally important and less important information from a lecture. The lecture involved a 20-minute videotaped presentation on bird migration. Learning was assessed using a free recall task 10 minutes after the lecture (immediate recall) and both free recall and probed recall tasks one week after the lecture (delayed recall). Data were analyzed using mixed factorial ANOVAs. Results indicated that the outline assisted the field-dependent students in recall of high structure information and field-independent students in recall of low structure information. Performance of field-dependent and field-independent students was equivalent on probed recall of low-structure information, but significant differences were found on the free recall of low-structure information. It is proposed that these differences are attributable to superior organizational abilities of the field-independent students and to use of the outline as a guide for retrieval.     

The effects of strategy training on high school students’ learning from science texts

This research examines the effects of a reciprocal teaching intervention aimed at providing high school students. with a repertoire of strategies to integrate text and visual aid information (graphs, diagrams) while learning in science. Experimental subjects received an hour of instruction each week for 7 weeks using SLIC (Summarise, Link, Image, Check) strategies to integrate the written word with the visual aid while Controls were taught under normal class teaching methods using the same materials. Post test ANOVA’s with Treatment (Experimental, Control) and Reading Ability (Average, Below average) as the factors showed superior recall of details by average ability students in the Experimental group but no significant differences in main idea recall nor on comprehension questions. All Experimental students included a graph in their recalls and they also significantly included more linking information in their texts on the graphs. The quality of their recall graphs was superior to those of the Control group. The results of a far transfer test showed no effects of training on transfer. Implications for future research and for teaching are discussed.     

In search of the keyword method/vocabulary comprehension link

Previous research has indicated that the keyword method of vocabulary learning facilitates students' performance not just on simple tests of definition recall, but on comprehension-demanding tasks as well. The present study was conducted to determine whether the “comprehension” finding could be accounted for by keyword subjects' superior definition recall per se. The results generally supported that conclusion: When conditions and subjects within conditions were equated with respect to their initial levels of definition recall, the comprehension advantage of keyword subjects disappeared.     

Teaching abstract vocabulary with the keyword method: effects on recall and comprehension

Twenty-five adolescents with learning disabilities were randomly assigned to either a keyword mnemonic condition or an experimenter-directed rehearsal condition and were individually taught 16 difficult vocabulary words, including 8 concrete and 8 abstract words. After an instructional period, students were given a test of literal recall as well as a comprehension test of their ability to apply newly acquired vocabulary words in a different context. Results indicated that mnemonically trained students outperformed control students on both abstract and concrete words, and on recall tests as well as on comprehension tests. Implications for vocabulary instruction as well as theories of learning disabilities are discussed.     

The Cognitive Process of Chinese Abacus Arithmetic

Based on the literature review about abacus arithmetic, this study proposes a model of the cognitive process of Chinese abacus arithmetic. This model describes three methods for solving abacus arithmetic problems: retrieval method, procedure method, and mental arithmetic method and three external factors that affect the choice of those methods: level of expertise, level of difficulty, and type of operation. The experiment in the study invited 36 participants including 12 vocational high-school students as junior experts, 12 ordinary high-school students as novices, and 12 bank clerks as senior experts to validate the 3 × 3 × 2 experiment. The results of this study indicate that (1) the retrieval method, procedure method, and mental arithmetic method are the three main calculation methods of abacus arithmetic, each of them having some variations; (2) experts tend to use the retrieval method, while novices tend to use the mental arithmetic method; (3) the retrieval method and mental arithmetic method are applied more for simple operations and addition problems, while the procedure method is applied more for complicated operations and subtraction problems.     

Retrieval Cues On Tests: A Strategy for Helping Students Overcome Retrieval Failure

Students often struggle to recall information on tests, frequently claiming to experience a “retrieval failure” of learned information. Thus, the retrieval of information from memory may be a roadblock to student success. I propose a relatively simple adjustment to the wording of test items to help eliminate this potential barrier. Specifically, I examined whether embedding salient information from class lectures in test items as retrieval cues enhanced student performance on tests. In two studies, including both an upper- and lower-division course, student performance on identical test items with and without retrievals was compared. Student performance varied significantly depending on whether retrieval cues were embedded in the items, and in both courses the difference was at least a half letter grade (study 2) or more (study 1). These results suggest that the selective use of retrieval cues on tests may be an effective strategy for helping students overcome retrieval failure on tests.     

A Study of the Influence of Some Factors in Style of Composition on the Interest,Comprehension, and Rate of Reading of Fourth-Grade Pupils

The research hypothesis was that memory strategy deficits can occur because of students' failure to understand the task and to evaluate their own performance. The effect of performance feedback on memory strategy use, performance evaluation, and recall was assessed with students with and without mild mental retardation with a mental age of approximately 8.5 years. For students with retardation, feedback resulted in more accurate performance evaluation and recall, but memory strategy use did not increase. By contrast, for students without retardation, feedback resulted in more accurate performance evaluation and greater recall accuracy and memory strategy use. We concluded that students with retardation may not have the appropriate memory strategies in their repertoire and, therefore, feedback does not result in strategy use. It seems likely that memory strategy use in this population would be increased by a training package that includes strategy instruction as well as feedback.

MENTAL STATUS AS A PREDICTOR OF RESPONSE TO MEMORY TRAINING IN OLDER ADULTS

The present study assessed the association between rated mental status and response to a memory‐training program. A commonly used general measure of cognitive impairment, the Mini‐Mental State Exam (MMSE), was administered to 102 elderly participants enrolled in a 2‐week memory‐training program. The program used two visual‐imagery mnemonics (name‐face recall and list learning by the “method of loci"). The MMSE scores were positively related to improvement in recall performance. Individuals with relatively mild deficits (those scoring below 29) showed less improvement than those scoring 29 and 30. Differences in ability to benefit from training were also noted between the two mnemonic devices, suggesting a more rapid fall off in ability to benefit from training with a more complex mnemonic, the method of loci.     

The keyword method compared to alternative vocabulary-learning strategies

Imagery and sentence versions of the keyword method of vocabulary learning were contrasted with three nonkeyword verbal-contextual alternatives. Subjects' definition learning in the imagery keyword condition was substantially higher than when subjects were presented the vocabulary in sentence contexts, when they generated sentence contexts for the words, when they made decisions about whether the words were used correctly in sentences, or when they were left to their own devices to learn the words. The learning benefits associated with the sentence keyword version were not as dramatic as in the imagery keyword condition. They were more evident when recall of any part of the definition was considered correct than when recall of the entire definition was necessary. These results indicate that the keyword method is a potent alternative to vocabulary-learning techniques that are regarded as effective by curriculum experts in reading.     

The effects of teaching notetaking strategies on elementary students’ science learning

The research examined effects of notetaking instruction on elementary-aged students’ abilities to recall science information and their notetaking behaviors. Classes of eight to nine years old third grade students were randomly assigned to three treatment conditions: strategic notetaking, partial strategic notetaking, and control, for four training sessions. The effects of the notetaking instruction were measured by their performances on a test about science information, a long-term free recall of the information, and the number of information units recalled with or without cues. Students’ prior science achievement was used to group students into two levels (high vs. low) and functioned as another independent variable in analysis. Results indicated significant treatment effect in favor of the strategy notetaking instruction groups on cued and non-cued recall of the information units. Students with higher prior achievement in science performed better on cued recall and long-term free recall of information. The results suggest that students as young as those in third grade classes can be instructed to develop notetaking ability that promotes their learning.     

The relationship between syntactic awareness and reading performance

This study was designed to examine the relationship between syntactic awareness and reading performance. A major concern was to provide an estimate of the effect of syntactic training that was not confounded with training that focused on semantic features of words. The training exercises used in the study focused on all levels of syntactic awareness in order that the effect of such training could be assessed on students’ performance on tasks that tapped each of the levels. Results of this study showed that syntactic awareness could be improved through training. The effect was stable, being apparent at the two post-test times. However, no evidence was found for a systematic effect of improved syntactic awareness on reading ability. Moreover, syntactic training did not show any greater effect than no treatment or semantic training on children’s grammatic comprehension, their ability to use fix-up strategies, or on their general reading ability score. Training had a different impact on the accuracy of oral reading for the syntactic and semantic training groups. Thus, in terms of the developmental sequence of syntactic awareness proposed by Gombert (1992), children trained in the cloze procedure improved at the two highest levels, whilst showing neither a corresponding change in the lower levels of awareness, nor improved functional reading performance.     

The seductive details effect in technology‐delivered instruction

Seductive details are highly interesting information tangential to course objectives. The inclusion of seductive details generally harms performance on recall tests, but few studies have used multimedia training or investigated effects on performance on recognition tests or transfer tasks. We conducted two studies using computer‐based training, instructing college students to use either Excel or Word mail merge. Contrary to most prior results, we found no negative effect for seductive details on recognition tests, and we found a facilitative effect on transfer performance. We discuss implications for theories of learning and transfer, and practical implications for instructional design and delivery.     

Ego depletion negatively affects knowledge retrieval in secondary school students

In the present study, we tested the assumption that performance in a knowledge retrieval test would be lower in secondary school students with temporarily depleted self-control strength (n = 53) compared to secondary school students with temporarily available self-control strength (n = 56). After manipulating self-control strength, students were instructed to memorise the names and the functions of the human eye and to recall as many names and functions as possible following a one-min distraction task. The results supported our assumptions, as students with depleted self-control strength performed significantly worse in the knowledge retrieval task compared to students whose self-control strength had not been temporarily depleted. The results suggest that depleted self-control strength may negatively affect academic performance and hinder a successful academic career. The theoretical and practical implications of these findings are discussed.     

Fostering learners’ metacognitive skills of keyword reformulation in image seeking by location-based hierarchical navigation

It is critical that students learn how to retrieve useful information in hypermedia environments, a task that is often especially difficult when it comes to image retrieval, as little text feedback is given that allows them to reformulate keywords they need to use. This situation may make students feel disorientated while attempting image searching. This study thus designed an image navigation tool, location-based hierarchical navigation support (LHINS), which can dynamically construct a compact WordNet-based hierarchy augmented by location. Using this tool, learners can assimilate new information based on their existing knowledge structure, thus avoiding cognitive overload so as to scaffold their metacognitive skills. Sixty-four high school students were invited to take part in an experiment to test the efficacy of the proposed tool compared to a normal keyword-based search (NKBS) system. The experiment evaluated not only the students’ task completion time in the NKBS and LHINS groups, but also their keyword reformulation process, in order to determine the differences in their metacognitive skills. The results revealed that the LHINS group tended to complete the tasks faster and develop better metacognitive skills related to keyword reformulation as compared to the NKBS group. This finding suggests that an image search engine, enhanced by a compact hierarchical navigation tool, can help learners develop better search strategies. When examining how learners with different cognitive styles used the tool, the results showed that learner performance depends on cognitive style, as well as the image retrieval system used, and thus a more detailed investigation of the interaction between the tool and cognitive styles was conducted. Based on these results, several suggestions are derived for designing a more powerful image navigation tool.
