Effects of learner control,advisement, and prior knowledge on young students' learning in a hypertext environment

This study was an investigation of the effects of learner control and of advisement in a hypertext learning environment with second-grade students who had different levels of prior knowledge about the content. Four treatment conditions crossing two variables, learner control (free access representing network structuring of hypertext vs. limited access representing hierarchical structuring of hypertext), and advisement (advisement vs. no-advisement), were established. From the quantitative and qualitative data, results indicated that: (a) for low prior knowledge (PK) students, the limited-access condition was more effective than the free-access condition, whereas high-PK students were able to function equally well in both conditions; (b) the free-access group reported a higher positive attitude for advisement than for no advisement, but the limited-access group showed no such difference in preference; (c) the low-PK group completed the lesson more quickly without advisement than with advisement, whereas the high-PK group's completion times did not vary across advisement conditions; and (d) analysis of the path data indicated that advisement was helpful in preventing disorientation in the free-access condition.     

Effect of adaptive advisement on perception in learner-controlled,computer-based instruction using a rule-learning task

The proposition that learner control of instruction can be facilitated by directly affecting the student’s perception of learning need was investigated. Students in one experimental condition were continuously advised during instruction of their learning performance and needs (amount and sequence of content) in relationship to the desired acquisition of rules at a given mastery criterion and were allowed to make instructional decisions. It was hypothesized that this condition would prove more effective on posttest performance than conditions without advisement — either partial learner control or conventional learner control. Results are discussed in reference to an information-processing approach to the design of computer-based instruction.     

Control of feedback in computer-assisted instruction

Although considerable research has been conducted on both learner control and feedback, very little research has addressed the effect of giving learners control over the feedback that they receive. The purpose of this study was to examine the effect of learner control over feedback in a CAI lesson. Subjects used one of four CAI programs which provided either program control or learner control over verification or elaboration feedback. Results indicated that subjects who received elaboration feedback during instruction performed better than students who received verification feedback. Type of control did not have a significant influence on performance. However, when subjects selected feedback for items answered incorrectly during instruction, subjects under learner control/elaboration performed better on the posttest than subjects under learner control/verification. Implications for the design of CAI are discussed.     

Accuracy of metacognitive judgments as a moderator of learner control effectiveness in problem-solving tasks

A possible explanation for why students do not benefit from learner-controlled instruction is that they are not able to accurately monitor their own performance. The purpose of this study was to investigate whether and how the accuracy of metacognitive judgments made during training moderates the effect of learner control on performance when solving genetics tasks. Eighty-six undergraduate students solved self-selected genetics tasks using either a full learner control or a restricted learner control. Results indicated that learner control effectiveness was moderated by the absolute accuracy (i.e., absolute bias) of metacognitive judgments, and this accuracy was a better predictor of learning performance for full learner control than for restricted learner control. Furthermore, students’ prior knowledge predicted absolute accuracy of both ease-of-learning judgments (EOLs) and retrospective confidence judgments (RCJs) during training, with higher prior knowledge resulting in a better absolute accuracy. Overall, monitoring guided control, that is, EOLs predicted time-on-task and invested mental effort regardless of the degree of learner control, whereas RCJs predicted the total training time, but not the number of tasks selected during training. These results suggest that monitoring accuracy plays an important role in effective regulation of learning from problem-solving tasks, and provide further evidence that metacognitive judgments affect study time allocation in problem solving context.     

The effect of competition and contextualized advisement on the transfer of mathematics skills a computer-based instructional simulation game

This study was designed to determine the effect of contextualized advisement and competition on transfer of mathematics skills in a computer-based simulation game in which participants helped their “aunt and uncle” fix up a house. Contextualized advisement referred to whether the participant had access to video-based advisement delivered by the aunt and uncle about how to solve the problem, and competition referred to whether or not the participant was playing against a computer character. A total of 123 seventh-and eighth-grade students were randomly assigned to one of five conditions formed by crossing the two independent variables and adding a control group. Results indicated an interaction between competition and contextualized advisement. Participants in the noncompetitive condition had higher transfer scores when they had access to contextualized advisement, while participants in the competitive condition had higher transfer scores when they had no access to contextualized advisement.     

Effects on children's achievement and curiosity of variations in learner control over an interactive video lesson

The purpose of this study was to evaluate the effectiveness of variations in learner control on children's level of curiosity and learning from computer-based interactive video (CBIV). The content was presented as a videodisc visit to an art museum and contained both facts and concepts. A posttest-only control group design was employed with 101 first-and second-grade subjects randomly assigned to one of three experimental conditions—Program Control, Learner Control, Learner Control with Advisement—or a control group. The dependent variables were achievement and three measures of curiosity. Children in the Learner Control with Advisement group scored significantly higher on the achievement posttest than the Learner Control subjects or control group. No differences were found between the Program Control and either of the Learner Control groups. For the curiosity measures, the Learner Control with Advisement subjects scored significantly higher than the control group on Content Exploration, and the subjects in the control group scored significantly higher than those in the Program Control group on Persistence.     

Developing a thirst for knowledge: How uncertainty in the classroom influences curiosity,affect, learning,and transfer

Uncertainty is a key variable in fostering curiosity, which, in turn, is associated with learning. Yet, research in educational contexts rarely takes uncertainty into account, and rarely explores uncertainty and curiosity in the context of complex instructional activities. One concern with uncertainty is that it can provoke negative affect. Providing learners with expectations of future uncertainty may attenuate their feelings of negative affect. In a study with 138 middle school students learning physics concepts, we examined the relationship between uncertainty, curiosity, learning, transfer, and affect. Some students were given an inherently uncertain form of instruction, called Invention, in which information on how to solve the problem was initially withheld, while others were given direct instruction with all the necessary information to solve similar problems beforehand (No Uncertainty condition). Some of the students receiving uncertain instruction were given expectations about feeling uncertain (Expected Uncertainty condition), and some were not (Unexpected Uncertainty condition). Students in the unexpected uncertainty condition were the most curious, while students in the no uncertainty condition were the least curious. However, giving expectations of uncertainty reduced students’ negative affect. All groups learned the content equally well, but the expected and unexpected uncertainty groups exhibited greater transfer. Further, positive affect predicted learning, above and beyond condition, and curiosity predicted transfer, but not above and beyond condition. This study extends existing research on uncertainty and curiosity by studying these constructs in real classrooms, in the context of an exploratory learning paradigm, and by considering curiosity’s effect on transfer, rather than just learning. This work also demonstrates a practical approach for educators to foster students’ curiosity and transfer.     

Continuity of individual adaptation from infancy to kindergarten: a predictive study of ego-resiliency and curiosity in preschoolers

In this longitudinal study, individual differences in security of attachment at 18 months and effective autonomous functioning at age 2 years were related to the dimensions of ego-control and ego-resiliency at age 4--5 years. The kindergarten or nursery school teachers of 26 children completed California Child Q-Sorts. The children were also given a short form of the Block's laboratory battery (Banta's curiosity box, level of aspiration, motor impulse control delay of gratification, the Shure and Spivack Preschool Interpersonal Problem-solving Test, and the Lowenfeld mosaics). Following the Blocks, composited ego-resiliency and ego-control scores were derived from each data set. Children earlier classified as securely attached were, as predicted, significantly higher on ego-resiliency on both laboratory and Q-sort composites. They were also higher than anxiously attached infants on 3 independent measures of curiosity. An independently composited index of competence from 2-year tool-using measures also correlated significantly with later resiliency, as did 2-year measures of mothers' support and quality of assistance. The data provide initial links between the infant's quality of attachment, the toddler's effectiveness in a problem-solving situation, and competence during the preschool years.     

Self-appraisal of Curiosity

Abstract

A 41-item self-rating inventory was developed for the purpose of determining whether such an instrument could be used to identify groups of children differing in curiosity as effectively as could combined teacher and peer rating. An estimated reliability of .91 had been obtained for the instrument by using the split-half method. The instrument was administered to groups of children differing in curiosity level who had been selected from 577 fifth-grade pupils attending suburban middle class schools. The groups were controlled for intelligence and had been subdivided by sex. In all cases, the differences between the means of high-curiosity children and the means of low-curiosity children were significant at the .05 level or better.

Sex-related differences in response to practice on a visual-spatial test and generalization to a related test

93 first graders (mean age 6.5 years) were given a pretest and posttest on half of the items from the Children's Embedded Figures Test. Half of the children were randomly assigned to a training condition and received a brief training procedure on visual-spatial disembedding prior to the administration of the posttest. Children in the control condition received no training. The performance of girls improved significantly more from pretest to posttest than the performance of boys. Boys and girls showed similar beneficial effects of training in addition to the benefit of direct practice. The tendency that was observed for boys to perform higher than girls on the pretest, p less than .10, was not evident on the posttest. Scores on the pretest predicted scores on a different measure of visual-spatial ability only for children in the control group. The results are interpreted in terms of current theories of sex differences in visual-spatial perception.     

Exploration of a Blended Learning Approach to Reading Instruction for Low SES Students in Early Elementary Grades

This study investigated the potential benefits of a blended learning approach on the reading skills of low socioeconomic status students in Grades 1 and 2. Treatment students received English language arts instruction that was both teacher-led and technology-based. Comparisons were made with control students who received the same English language arts instruction without the blended learning component. Results showed significantly greater pretest/posttest gains on a standardized reading assessment for the treatment students compared to the control students. The greatest discrepancy occurred in reading comprehension. A sub-analysis of low-performing English language learner students in the treatment group revealed the largest reading gains. At posttest, these students performed at the level of non-English language learner students in the control group. Results indicated a blended learning approach can be effective in enhancing the reading skills of low socioeconomic students.     

Convergent and Divergent Thinking,Test-Anxiety,and Curiosity

Interrelationships between two motivational variables, test-anxiety and curiosity, and two cognitive variables, convergent and divergent thinking were tested using the measures of convergent and divergent thinking of J. P. Guilford and two self-report true-false scales of test-anxiety and curiosity. Ss were 212 undergraduates, 175 female and thirty-seven male. Based on findings and implications from earlier research, negative relationships of convergent and divergent thinking with test-anxiety, and positive relationships with curiosity were predicted. All correlations for the total group were found to be significant at the .05 level, those with anxiety higher than those with curiosity. Thus, there was support for the view that test-anxiety is negatively related and curiosity positively related to both convergent and divergent thinking. The results were discussed in terms of previous research, and educational implications.     

Effects of a Teacher Training Workshop on Creativity,Cognition, and School Achievement in Gifted and Non-gifted Second-grade Students in Lima,Peru

Enrichment for the gifted in the regular classroom was studied with a teacher training workshop developed for the purposes of this study. Participants were 231 second-graders of Lima public schools (in Peru). The instruments used, TCT-DP and the CogAt test, were first culturally adapted to the Lima context. Results reveal a significant ability 2 time interaction in figural-creative performance and a condition 2 time significant interaction effect. Also, analysis of school achievement showed an ability 2 time interaction effect. These findings argue for the further development and use of teacher training programs in educating the gifted within the regular classroom in Lima public schools.     

Intervention in the motor domain: A training study with first- and second-grade slow readers

A burgeoning interest in learning disabilities during the past five years has aroused educational interest in the hypothesized sequence of motor, perceptual, and symbolic development. The present research was undertaken to test the effectiveness of beginning training at the motor level for children having difficulty with the symbolic system of reading. First- and second grade children were screened on the Gates Primary Reading Test and all motor subtests of the Purdue Perceptual-Motor Survey. The final sample comprised 35 children randomly assigned to one of three treatment groups: Motor Training, Physical Education, and Reading Control. Variables of teacher differences, adult-child ratio, amount of physical activity, and Hawthorne effect were controlled for in the design. Kruskal-Wallis analysis of variance and an analysis of covariance on a parallel form of standardized reading test showed a consistent pattern of greater gains following motor training and reading activities, and minimal progress after the physical education treatment. It was hypothesized that this may reflect effects of structured experiences and more equal distribution of teacher-child interaction. Reading gains of the first-grade children were significantly greater than those of the second-graders beyond the 0.01 level, a result not explainable by ceiling effects. Implications of the slower progress of the older children were explored in terms of a need for focus on particular reading subskills across perceptual-motor-symbolic systems.     

Improving second language skills of immigrant students: A field trial study evaluating the effects of a summer learning program

Immigrant students’ school success is often hampered by limited second language (L2) proficiency, yet the effectiveness of different approaches to L2 support is unclear. Using a summer camp setting, we tested effects of (1) implicit support focusing on meaning of language by engaging students in language-intensive activities without drawing their attention to rules (operationalization: theatre program) and (2) combined implicit and explicit support focusing students’ attention on both meaning and form of language (operationalization: theatre program and instruction in German as L2). A baseline group received no support. N = 149 third-graders with German as L2 participated. There was no effect for the implicit condition on L2, yet children in the combined condition performed significantly better in grammar and reading after the treatment than the baseline group. The difference for vocabulary did not reach significance. Three months later, a significant effect for the combined condition was only found for reading.     

Strategic aspects of simple addition and subtraction: the influence of mathematical ability

This study investigated ability-related differences in strategy use and development in the domain of simple arithmetic, in terms of the model of strategic change, using the choice/no-choice method and the chronological-age/ability-level-match design. Twenty-six second-graders with strong mathematical abilities (MA), 25 second-graders with weak MA, and 20 third-graders matched on MA with the strong second-graders solved 36 additions and subtractions with the bridge over 10 in 4 conditions. In the choice condition, children could choose between retrieval, decomposition to 10, and counting on. In the three no-choice conditions, they had to solve all problems with retrieval, decomposition to 10, or counting on. Results revealed differences in strategy use between strong and weak second-graders, but not between strong second-graders and matched third-graders, which indicates that the strategy development of children with weaker MA is marked by a delay. The theoretical, methodological, and practical implications of the study are discussed in detail.     

Instructional Design of Web-based Simulations for Learners with Different Levels of Spatial Ability

This study, the purpose of which is to determine an efficient instructional design for different levels of spatial abilities, investigates: (1) the main effects of visual treatments in simulation environments on comprehension and the transfer of chemistry knowledge and (2) the interaction effects of the visual treatments and the learners’ spatial abilities. Two hundred and fifty-seven middle school students were randomly assigned to two experimental conditions. The results indicated: (1) a significant main effect of the treatment condition for both comprehension (p < 0.001) and transfer (p < 0.005) tests, where the treatment group performed better than the control group and (2) a significant interaction effect (p < 0.05) between the instructional treatment conditions and level of spatial ability for the comprehension test: Low spatial ability learners performed better in the treatment group than in the control group, whereas high spatial ability learners performed similarly regardless of the instructional conditions.     

Evidence for different parent–child strategies while reading

This study examined the strategies parents use naturally to help early readers at difficult points of text or pronunciation. Forty‐two children were videotaped reading to a parent. Results suggest parents are not likely to provide specific instructional feedback when listening to their children read. When given, parental feedback tends to be well tuned to the child's reading ability, with parents of less skilled readers providing richer and more varied feedback than parents of more skilled readers. A tree clustering analysis placed parents in one of three groups: 1) ‘Learner centred’ parents use a variety of feedback strategies; 2) ‘Inactive’ parents allow their children to continue uncorrected; 3) ‘Direct’ parents supply the miscued word. The children of ‘learner centred’ parents did not perform as well as children of ‘inactive’ parents on measures of reading ability, possibly because parents of better readers no longer need to be ‘learner centred’.
