Effects of incorporating retrieval into learning tasks: The complexity of the tasks matters

In an experiment with N = 192 university students, we examined whether the effects of incorporating retrieval into learning tasks depend on the learning tasks' complexity. The learning tasks consisted of adjunct questions that were provided together with expository texts relating to the domain of chemistry. We varied (a) whether the adjunct questions required the learners to summarize (low complexity) or generate inferences on the basis of provided information (high complexity) and (b) whether the adjunct questions were implemented in a closed-book style that required learners to engage in retrieval or in an open-book style that did not require learners to engage in retrieval while responding to the questions. Afterwards, all learners took either an immediate or a delayed criterion test. We found that the effect of incorporating retrieval depended on the complexity of the adjunct questions; the net benefit of incorporating retrieval was higher for the low complexity ones.     

Selecting learning tasks: Effects of adaptation and shared control on learning efficiency and task involvement

Complex skill acquisition by performing authentic learning tasks is constrained by limited working memory capacity [Baddeley, A. D. (1992). Working memory. Science, 255, 556–559]. To prevent cognitive overload, task difficulty and support of each newly selected learning task can be adapted to the learner’s competence level and perceived task load, either by some external agent, the learner herself, or both. Health sciences students (N = 55) participated in a study using a 2 × 2 factorial design with the factors adaptation (present or absent) and control over task-selection (program control or shared control). As hypothesized, adaptation led to more efficient learning; that is, higher learning outcomes combined with less effort invested in performing the learning tasks. Shared control over task-selection led to higher task involvement, that is, higher learning outcomes combined with more effort directly invested in learning. Adaptation also produced greater task involvement.     

Cultivating student skills in self-regulated learning through evaluation of task complexity

In order to self-regulate, students need to honestly reflect on their learning and to take appropriate corrective action. A simple procedure to cultivate student skills in self-regulated learning, known as the Task Evaluation and Reflection Instrument for Student Self-Assessment (TERISSA) is discussed in this paper. TERISSA guides students through two evaluations of the complexity of a task: the first is undertaken just before solving the task and the second straight after completing the task. This study involved 63 undergraduate students and observed a statistically significant difference (p = 0.007) in performance between the students who did (6.1/10) and did not (4.1/10) use TERISSA during tutorials leading up to an assessment task.     

Resource interdependence,student interactions and performance in cooperative learning

Two studies were carried out during university workshops, and analyzed the effects of resource interdependence on student‐student interactions, and the impact of these interactions on performance. Students worked cooperatively, either on complementary information (positive resource interdependence) or on identical information (resource independence). In Study 1, analysis of videotaped interactions revealed that working on complementary information produced more positive interactions; however this was not sufficient to prevent students who had no direct access to the information from being disadvantaged, because of informational dependence. In Study 2, with simpler texts allowing better information transmission, performance was favored when students worked on complementary information. Moreover, working on identical information not only enhanced confrontations of point of views, it also elicited competence threat. Further analysis revealed that competence threat mediated resource interdependence effect on performance. Discussion provides insights into the conditions in which different cooperative methods can benefit learning.     

Rats' performance on an interval time-place task: Increasing sequence complexity

Rats were trained on an interval time-place learning (TPL) task in which the location of food availability depended on the time since the start of the session. Each of four levers (numbered 1, 2, 3, 4) provided food on an intermittent schedule for two nonconsecutive 3-min periods. The order in which the levers provided food was 1, 2, 4, 3, 2, 3, 1, 4. This order was consistent across sessions. Previous research conducted in our lab has shown that when only four “places” are used, rather than the eight in the present study, rats use a timing strategy to track the location of food. Pizzo and Crystal (2004) recently trained rats on an interval TPL in which each of eight arms of a radial arm maze provided food. They found evidence suggesting that rats used both spatial and temporal information. In the present study, in which a revisiting strategy was used (i.e., each lever provided food on more than one occasion), the rats tracked both the spatial and the temporal availability of food for the first half of the session. Interestingly, in the second half of the sessions, the rats appeared to be timing the availability of food even though they did not know where it would occur. That is, the rats knew the temporal, but not the spatial, contingencies for the second half of the session. It appears that the requirement of revisiting a previously reinforced lever resulted in rats' no longer being able to solve the spatial aspect of the task.     

Exploring the relationship between homework task difficulty,student engagement and performance

This article considers the relationship between differential homework task difficulty, student engagement and performance across four Irish post-primary school sites. A total of 236 participants completed all elements of this study. All participants were junior cycle students, aged between 12 and 16 years. The study employed a standardised test–retest approach, with a one week interval between tests. Between testing, participants were randomly subdivided into three cohorts. Each cohort received homework questions of different difficulty levels to complete for one week. The results of this study found that Cohort A, who received the least difficult homework tasks, completed the most non-compulsory questions. Although Cohort A demonstrated higher levels of engagement, no statistically significant difference was found in the change in performance scores of the three cohorts. The results highlight the negative impact of increased task difficulty on student engagement with independent homework tasks. The findings suggest that in order to support student engagement it is important that teachers afford ample opportunity for student success when designing self-directed tasks such as homework.     

The effect of task alternatives on vocabulary knowledge: a comparison of students with and without learning disabilities

This study used a two-part task format to (a) describe the vocabulary knowledge of 10- and 12-year-old students with learning disabilities and (b) assess the effect of task alternatives on their vocabulary knowledge. We addressed these research objectives by comparing the performance of 24 students with learning disabilities to an equal number of their normally achieving peers. Vocabulary knowledge was first assessed through a production task. In the even the student's response was inaccurate or incomplete, an identification task assessing the same vocabulary term was presented. Results revealed that, compared to normally achieving students, students with learning disabilities are (a) significantly less able to construct fully specified responses to production tasks, (b) comparable in their ability to use pictorial responses to demonstrate vocabulary knowledge not accessible in production tasks, and, (c) when equated in reading achievement, only 10-year-olds are significantly poorer in composite vocabulary knowledge.     

Comparative performance in discrimination learning tasks in two New World primates (Saimiri sciureus andCallicebus moloch)

Squirrel monkeys (Saimiri sciureus) and titi monkeys (Callicebus moloch) were tested in three two-choice visual discrimination experiments. Although, on average, squirrel monkeys performed more accurately than titis, the range of response accuracies in the two species overlapped considerably in all three experiments and changes in response accuracy over test sessions and across experiments were similar in the two species. Thus, the species shared several behavioral characteristics expected of New World primates in this setting. Squirrel monkeys’ performance appeared to be more affected than titis’ by task difficulty, and squirrel monkeys were individually less consistent than titis. These differences were associated with higher activity levels and briefer overt attentiveness to the repetitive task in squirrel monkeys and, conversely, with lower activity levels, slower working speeds, and sustained interest in the task in titis. The associated differences are discussed in relation to each species performance in other laboratory settings and the characteristic patterns of foraging and use of space in nature.     

Vocabulary learning from reading: examining interactions between task and learner related variables

In the field of second and foreign language learning, how various task characteristics affect language learning has been the focus of many recent studies. Much of this research examined the relationship between task characteristics and task performance without fully taking into account learner related variables. The present study aimed to assess task complexity and sequence in relation to the learner related variables drawn from the social cognitive perspective of self-regulated learning, i.e. self-efficacy beliefs and frequency of learning strategy use, as they were applied to two versions of vocabulary learning from reading tasks. The tasks designed for the present study were based on the componential framework for second language task design. With tasks and task sequence counterbalanced, 146 first-year university students (mean age?=?18.59 years) were randomly assigned to one of four groups. Results reveal a significant effect of task sequence on vocabulary learning self-efficacy beliefs, frequency of learning strategy use and task performance, and a significant interaction effect of sequence with task complexity. Findings are discussed in terms of complex interactions between task and learner factors.     

Example-based learning: Effects of different types of examples on student performance,cognitive load and self-efficacy in a statistical learning task

Previous research has indicated the disconnect between example-based research focusing on worked examples (WEs) and that focusing on modeling examples. The purpose of this study was to examine and compare the effect of four different types of examples from the two separate lines of research, including standard WEs, erroneous WEs, expert (masterly) modeling examples, and peer (coping) modeling examples, on student performance (knowledge retention, near transfer, and far transfer), cognitive load, and self-efficacy. One hundred and sixteen students participated in the study by undergoing computer-based instruction in one of the four versions differing in how examples were provided. The results showed that, overall, expert modeling examples were most effective in promoting knowledge retention, near transfer, and far transfer, while peer modeling examples were shown to be superior in fostering self-efficacy among the four different types of examples.     

Grades degrade group coordination: deteriorated interactions and performance in a cooperative motor task

At school, pupils often cooperate on common projects and must coordinate their different individual actions. However, grades are pervasively used even in cooperative situations, which make the pupils’ differences in achievement and their relative rank salient and may reduce their inclination to work constructively with others. Thus, we hypothesized that grades would elicit disruptive interactions and reduce performance in a cooperative cognitive-motor task necessitating inter-individual coordination of members. In a study with 5th graders, grades (vs. a neutral concept) were primed at the onset of a cooperative group interaction. Results showed that, although pupils were set to work cooperatively, priming grades (vs. neutral concepts) harmed inter-individual coordination by eliciting more negative dominant behaviours among pupils during interactions, which decreased group performance.     

Exploring the relationship among learning patterns,personality traits,and academic performance in freshmen

Providing information about how 1st-year students learn may help colleges plan actions aimed at increasing students' persistence in higher education programs. This research aims to assess 1st-year students' academic performance, using a path analysis to establish inter-correlations among students' personality traits, learning patterns, high school achievement, and objectively measured outcomes. Participants included 509 freshmen from different academic disciplines. Results show a causality relations model in which Conscientiousness positively influences Sequential and Precise learning patterns as well as academic performance. The path model also confirms Extraversion as a negative antecedent of the Technical learning pattern. It is argued that knowing students is a primary step to putting them in a position to become an active part of the learning process.

Exploring the role of flow experience,learning performance and potential behavior clusters in elementary students' game-based learning

Well-designed game-based learning can provide students with an innovative environment that may enhance students' motivation and engagement in learning and thus improve their learning performance. The purpose of this study was to examine the relationships among elementary school students' flow experience and learning performances. We also investigated the gender and grade differences as well as the types of potential clusters of flow experiences and performance. Thirty-four elementary school students participated in this study. This study conducted correction analysis, difference analysis and a two-stage cluster analysis. The findings suggested that the students with higher flow experiences tended to have higher learning performances. The results of gender differences showed that female students had high performance scores and great flow experiences in the mini-educational game in this study. Moreover, the results revealed that the students of higher grade had significantly higher scores in both performance and flow experience than the students of lower grade. The result of cluster analysis fell into three categories: low performance/low flow experience students, high flow experience students and high performance/high flow experience students. On the basis of our findings, we also proposed suggestions for future game-based learning research.     

Orthographic analogies and early reading: Explorations of performance and variation in two transfer tasks

Two experiments investigated the use of orthographic analogies in 6 year olds. In Experiment 1, 26 children were shown CVC clue and target word pairs sharing either rimes (`fork' – `pork'), heads (`fork' – `ford') or were controls (`fork' – `hurl'). A modest advantage for rime-clued over head-cluedtargets was unreliable over by-subject and by-item analyses. Improvements in target word reading were correlated with pretest scaffolding errors (e.g. `pork' misread as `park'). In Experiment 2, 50 children were pretaught three clue words for each target word before being shown words that shared either rimes (`leak' – `peak'), or medial vowel digraphs (`leak') – `bean'), or were controls (`leak' – `herd'). A modest advantage for rime-clued over vowel digraph-clued targets was again unreliable over by-subject and by-item analyses. Neither rime nor phoneme awareness measures were correlated with rime inference use. Vowel, but not rime inference, was correlated with scaffolding errors. Rime detection was the strongest predictor of reading ability, whereas phoneme segmentation was the strongest predictor of the use of scaffolding errors.     

Perception of boys’ mother-son social interactions: Disruptive boys’ behaviors and involvement in learning tasks

This study focused on the relationship between social perception and children’s involvement in learning tasks. The interaction between disruptive boys’ (n=32) perception of the competence attributed to them by their mother, the mother’s behavior (verbal and physical intrusion) and the child’s involvement in learning tasks was observed in a laboratory setting. Boys were asked to solve easy and difficult tasks on a personnal computer under the supervision of their mother. Observations of mother-child interactions showed that disruptive boys with a negative perception of the competence attributed to them by their mother, were less involved in the difficult task than boys who had a positive perception. Mothers of the boys with a negative perception showed more verbal intrusions in the easy task and more physical intrusions in the difficult task than the mothers of boys with a positive perception. Mothers’ verbal intrusion, physical intrusion and boys’ involvement in the task discriminated 75% of the boys with a negative social perception. These results seem to indicate that disruptive boys do not constitute an homogeneous group and that a significant variation in their involvement in a learning task is related to their perception of the competence attributed to them by their mother.

The relationship of estimated learning potential to performance on a learning task and achievement

The Estimated Learning Potential (ELP), a score obtained through the System of Multicultural Pluralistic Assessment (SOMPA), is purported to be a more appropriate index of potential for socioculturally different children. Prior studies have suggested a lower correlation with academic achievement than that of the traditional IQ score. The validity of the ELP has, therefore, been questioned. This study attempted to determine whether the ELP or IQ score would be the better predictor of performance on a learning task for 31 black and 32 white EMR children. The learning task was presented in a test-teach-test paradigm. Results suggest that the ELP did not correlate more highly with learning task performance than did the IQ score. However, the ELP may be more differentially sensitive to declassifying black children as retarded. The validity and the social consequences of the use of the IQ, ELP, and performance, after teaching, on the learning task for classification decisions also are discussed.
