A model for optimizing step size of learning tasks in competency-based multimedia practicals

Learners are often overwhelmed by the complexity of realistic learning tasks, but reducing this complexity through traditional Instructional Design (ID) methods jeopardizes the authenticity of the learning experience. To solve this apparent paradox, a two-phase ID model is presented. Phase 1 consists of cognitive task analysis, where a systematic approach to problem solving (SAP) is identified in conjunction with skill decomposition and determination of task complexity. In the subsequent design phase, inductive micro-level sequencing based on the four-component ID model (van Merriënboer, 1997) is applied where worked-out examples and problems accompanied by process worksheets assure the necessary variability of practice. Step size in a multiple-step whole-task approach—needed for the process worksheets—is determined on the basis of estimated part-task complexity. A developmental study of the model is illustrated with examples from the domain of law.     

An Examination of the Promise of the NumberShire Level 1 Gaming Intervention for Improving Student Mathematics Outcomes

ABSTRACT

The purpose of this study was to test the promise of the NumberShire Level 1 Gaming Intervention (NS1) to accelerate math learning for first-grade students with or at risk for math difficulties. The NS1 intervention was developed through the Institute of Education Sciences, Small Business Innovation Research Program (Gause, Fien, Baker, & Clarke, 2011 Gause, M., Fien, H., Baker, S. K., & Clarke, B. (2011). Project NumberShire I: A game-based integrated learning and assessment system to target whole number concepts. (Subcontract with Thought Cycle, U.S. Department of Education, Institute of Education Sciences, Small Business Innovation Research Program, 2011–2013, Funding Number: EDIES11C0026, $1,049,954). [Google Scholar]) as a digitally based technology tool to allow educators to intervene early and strategically with students struggling to learn mathematics. This study used a randomized controlled trial design to test the promise of the NS1 intervention. In total, 250 first-grade students were randomly assigned within classrooms to the treatment condition or a control condition. Results indicate significant effects favoring the treatment group on proximal measures of whole-number concepts and skills. Intervention effects were not statistically significant for distal outcome measures. Treatment effects were not moderated by special education or English learner status; however, the condition by initial skill level interaction approached significance. Additionally, there was no relationship between dosage variables and students' response to the intervention. Limitations and future directions for research are discussed.     

The impact of L1 writing system on ESL knowledge of vowel and consonant spellings

Orthographic knowledge, the general ability to learn, store, and use information about the orthographic form of words (Stanovich & West, 1989), is a crucial skill for supporting literacy. Although the development of first language (L1) orthographic awareness is impacted by the characteristics of a learner’s L1 writing system, relatively little is known about what impact the L1 may have on second language (L2) orthographic awareness. In this study, English language learners from three L1s (French, Hebrew, Mandarin Chinese), plus L1 English speakers, were tested on their English spelling knowledge using a word-pseudohomophone discrimination task. In addition to allowing for the cross-linguistic comparisons, items were designed to examine whether learners had differing performance on pseudohomophones (misspellings) that targeted vowels versus consonants. Consistent with previous research (e.g., McBride-Chang, Bialystok, Cong, & Li, 2004), the L1 Chinese speakers had the highest (L2) accuracy, followed by the L1 Hebrew and the L1 French speakers. The participants from non-alphabetic languages (Hebrew and Chinese) had significantly lower accuracy on items with misspellings involving vowels compared to consonants, and the size of the vowel-consonant accuracy difference varied substantially across L1 groups. The results demonstrate that the characteristics of a learner’s L1 writing system, particularly the existence of vowel and consonant graphemes, impact the development of L2 orthographic knowledge and sensitivity to different types of word misspellings.     

Levels of phonological awareness and learning to read

The paper reports studies of segmentation performance by a Nursery group of children, who had not yet started to learn to read, and by Primary 1 and 2 groups, who were in the early stages of learning by a standard method of whole word acquisition combined with letter-sound learning. Rhyme and alliteration production tasks were applied, together with segmentation tasks requiring division of monosyllabic words or non-words of simple or complex structure into two parts, three parts, or as many parts as possible. Performance was related to the hierarchical model of the syllable which distinguishes a two-dimensional (2D) level (onset/rime), a three-dimensional (3D) level (initial consonants, vowel, terminal consonants) and many-dimensional (nD) level (phonemes). The hypothesis that phonological awareness (PA) normally develops down the hierarchy, from larger to smaller units, predicts that segmentation ability should emerge in the sequence 2D 3D nD. In practice, the reverse of this order was found. The results are discussed in relation to theories of the relationship between literacy development and the different levels of PA.     

Cognitive Load Theory: A Broader View on the Role of Memory in Learning and Education

According to cognitive load theory (CLT), the limitations of working memory (WM) in the learning of new tasks together with its ability to cooperate with an unlimited long-term memory (LTM) for familiar tasks enable human beings to deal effectively with complex problems and acquire highly complex knowledge and skills. With regard to WM, CLT has focused to a large extent on learning task characteristics, and to a lesser extent on learner characteristics to manage WM load and optimize learning through instructional design. With regard to LTM, explanations of human learning and cognition have mainly focused on domain-general skills, instead of domain-specific knowledge held in LTM. The contributions to this special issue provide a broader cognitive load view on the role of memory in learning and education by presenting the historical roots and conceptual development of the concept of WM, as well as the theoretical and practical implications of current debates about WM mechanisms (Cowan 2014), by presenting an updated model of cognitive load in which the physical learning environment is considered a distinct causal factor for WM load (Choi et al. 2014), by an experimental demonstration of the effects of persistent pain on the available WM resources for learning (Smith and Ayres 2014), and by using aspects of evolutionary educational psychology to argue for the primacy of domain-specific knowledge in human cognition (Tricot and Sweller 2014).     

Effects of disfluency and test expectancy on learning with text

Do students learn better with texts that are Open image in new window (i.e., disfluent)? Previous research yielded discrepant findings concerning this question. To clarify these discrepancies, the present study aimed at identifying a boundary condition that determines when disfluent text is, and is not, beneficial to learning. This boundary condition is knowledge about whether a test will follow (high test expectancy) versus not (low test expectancy). Participants with high test expectancy may already engage in effortful processing, so that making text harder-to-read (disfluent) might not change their processing mode any further. Thus, particularly when no test is expected, disfluency is supposed to exert its beneficial effect. This assumption was tested in a 2?×?2 design (N?=?97) with text legibility (fluent vs. disfluent) and test expectancy (low vs. high) as factors, and learning outcomes (retention, transfer) and learning times as main dependent variables. Results revealed that high test expectancy led to better learning outcomes (for retention and transfer), but disfluent text did not. Unlike expected, there was no interaction between the two factors. Moreover, both high test expectancy and disfluency led to longer learning times, resulting in a lower efficiency when learning with disfluent compared to fluent text. Hence, the present results further question the stability and generalizability of a positive disfluency effect on learning, because only high test expectancy – but not disfluency - stimulated better learning through more effortful processing the way it was supposed to.     

Removing but not adding elements of a context affects generalization of instrumental responses

Three experiments with rats investigated whether adding or removing elements of a context affects generalization of instrumental behavior. Each of the experiments used a free operant procedure. In Experiments 1 and 2, rats were trained to press a lever for food in a distinctive context. Then, transfer of lever pressing was tested in a context created either by adding an element to the context of initial acquisition or by removing one of the acquisition context’s elements. In Experiment 3, a similar generalization test was conducted after rats received acquisition and extinction within the same context. For Experiments 1 and 2, we observed that removing elements from the acquisition context disrupted acquisition performance, whereas the addition of elements to the context did not. Experiment 3 revealed that removing elements from but not adding elements to the original context improved extinction performance. Our results are consistent with an elemental view of context representation.     

Practical Skills Training in Agricultural Education—A Comparison between Traditional and Blended Approaches

Purpose: In this article the use of blended learning multimedia materials as an education tool was compared with the traditional approach for skills training.

Design/Methodology/Approach: This study was conducted in Ireland using a pre-test, post-test experimental design. All students were instructed on how to complete two skills using either a traditional or blended methodology. They were subsequently assessed to determine their ability to perform the practical skills.

Findings: The findings stressed the suitability of blended learning not only when it was found that there was no significant difference between method of teaching and skill acquisition but also when it was revealed that student demographics had no major influence on skill acquisition.

Practical Implications: It can be concluded that blended learning can be used effectively for the instruction of a diverse range of practical skills in agricultural college and benefit in the successful knowledge transfer to a growing and diverse student population with more emphasis placed on the students taking charge of their own learning environment.

Originality/Value: The article demonstrates the value of blended learning as a successful medium for practical skill attainment within the agricultural college environment.

Appropriation des proprietes ordinales du nombre par l'eleve du cours preparatoire

The aim of this research is the clarification of the process whereby the learner, in the first year of compulsory education (Cours Préparatoire) constructs and internalizes the concept of natural number. The research is based on a close and rigorous analysis of learners' behaviour when confronted with problem situations designed according to a priori established priorities. This analysis is based on one-to-one interviews, a method which enables the dynamics of the processes involved for each learner, and thus the evolution of his cognitive system with respect to the task in hand, to be apprehended.In this paper, in a problem situation called The Race, we examine the functioning of ordinal properties of natural numbers, the acquisition of which plays an important role, both at the level of the construction of the concept of number and at the operational level. We show, in particular, that while the majority of learners at the end of the Cours Préparatoire are capable of supplying the preceeding and following numbers in the numerical field [1, 30], and that while they can count starting from a number other than one within this field, they nevertheless experience many difficulties with respect to the functioning of properties, such as, for example, cardinal-ordinal relations, or the property of rank invariance.Furthermore, even when one of the properties under consideration functions in a given situation, this, in itself, does not mean that the learner has acquired it. The learner may, at a later date, no longer be able to use it, or, alternatively, when the situation is slightly modified he may overgeneralize, as the functioning of these properties depends both on the learner's current mathematical competence and on the tasks which confront him.     

Hypothetico-deductive reasoning skill and concept acquisition: Testing a constructivist hypothesis

This study tested the constructivist hypothesis that the acquisition of domain-specific conceptual knowledge (declarative knowledge) requires use of general procedural knowledge. More specifically, it was hypothesized that use of a general pattern of hypothetico-deductive reasoning is necessary for the acquisition of novel domain-specific concepts. To test this hypothesis 314 high school biology and chemistry students were first tested to determine whether or not they were skilled in the use of hypothetico-deductive reasoning. Based on this test, students were classified as reflective, transitional, or intuitive thinkers. All students were then presented with a series of four concept-acquisition tasks. It was predicted that reflective (hypothetico-deductive) thinkers would acquire the concepts while intuitive (empirico-inductive) thinkers would not. Transitional thinkers were expected to be partially successful. These predictions were confirmed as skill in hypothetico-deductive reasoning (developmental level), but not age, was highly correlated with performance on the concept acquisition tasks (X² = 71.14, p < 0.00001). This result was interpreted to be supportive of the constructivist hypothesis.     

Vicarious learning from dialogue and discourse

This study examined learning in the domain of sentence parsing and syntax treediagram construction. The aim of the study was to assess whether subjects could learn vicariously from recordings of interactions between a previous student and a tutor.Four intervention conditions and a control condition were compared. Subjects in a dialogue group (DL) read printed tutorial notes and subsequently vicariously viewed dynamic (animated) recordings of tree diagrams being constructed by a previous student in the presence of a tutor.The discourse (DI) condition was similar except that subjects viewed recordings of tree diagrams being constructed by a tutor who concurrently verbalised instructional discourse.In a third condition (DO), subjects viewed tree-diagram construction animation clips which were not annotated with either dialogue or discourse. In a linear text (LT) condition, subjects were given only printed tutorial notes. A control (CO) condition involved pre and post testing without any intervention.Results indicated that the dialogue condition was as effective as the discourse condition. This provides support for contention that re-usable dialogue is a useful resource for the vicarious learner. Another finding was that un-annotated animated diagrams were surprisingly effective. Several reasons for their effectiveness are suggested from the literature on instructional animations.     

CURRICULUM RESEARCH IN SWEDEN IV‐‐THE GYMNASIUM AND PRE‐UNIVERSITY EDUCATION

Fifty‐six children between the ages of two years four months and four years ten months were given tests relating to the acquisition of both ‘specific’ and ‘generic’ concepts. Several tests of concept acquisition (HAPCAT) ^{1 1}The tests may be obtained from the NFER (Guidance and Assessment Service) to whom inquiries should be addressed. were devised by the authors utilizing pictures drawn on card. A number of the children (N=29) were also given some ‘Piagetian questions’ concerning class inclusion.

The results conflict with the widely held view (following the writing of Jean Piaget) that preschool children cannot form generic concepts. Nearly all the children were able to identify the specific concepts as presented in the HAPCAT items and about half the group responded appropriately to the HAPCAT items involving an understanding of generic concepts. There was a clear and statistically significant relationship between the number of correct answers given to the HAPCAT items and the age and ability levels of the children. This was not the case, however, with the Piagetian test questions which showed no discriminatory power in these respects. It is argued that the Piagetian questions do not represent a sensitive or meaningful measure of concept acquisition at this age level whereas the HAPCAT items do appear to present pre‐school children with intelligible tasks which allow many of them to demonstrate an understanding of generic concepts involving class inclusion.

     

Vicarious learning from dialogue and discourse -- A controlled comparison

Why don’t guiding cues always guide in behavior chains?

This research focused on the changes in stimulus control that influence an animal’s ability to master a behavioral skill. We assessed stimulus control by (a) predictive environmental cues (panel lights) and (b) practice cues resulting from the subject’s own behavior, as rats learned to complete a left–right lever-press sequence. Following a demonstration of overshadowing by Reid, Nill, and Getz (Behavioural Processes 84: 511–515, 2010), in which stimulus control by the panel lights overshadowed control by practice cues, four additional experiments replicated and assessed this overshadowing effect. In Experiment 1, we discovered a powerful asymmetry: Rats failed to adapt to a lights → reversed-lights transition, but adapted immediately to a reversed-lights → lights transition. Experiment 2 was designed to measure the interactions between these stimulus conditions and practice cues. In Experiment 3, we measured the effect of these stimulus conditions on acquisition rates. Finally, in Experiment 4 an ABA design was used to assess the effects of prior exposure to condition A on B → A transitions, and we found that prior exposure generally reversed the effects observed in B → A transitions presented first or in isolation. We discuss feature-positive bias and spatial S–R compatibility as potential explanations of the observed insensitivity to cues that should be, at face value, highly predictive of food during the acquisition of a behavioral skill. Perfectly predictive cues in behavior chains do not always guide behavior.     

Calling Iranian learners of L2 English: effect of gloss type on lexical retention and reading performance under different learning conditions

This study sought to compare how three different gloss types (text–picture, text–audio and text–picture–audio) affected English as a foreign language (EFL) learners' reading comprehension and vocabulary acquisition. The study also compared how results on comprehension and vocabulary acquisition differed across three learning conditions (i.e., incidental, intentional and explicit instruction). A between‐groups design was employed with four groups (N = 135) of Iranian university learners of L2 English. The participants (with upper‐intermediate proficiency level) read English texts. Written recall and multiple‐choice questions were used to measure reading comprehension; vocabulary knowledge scale (VKS) and contextualized vocabulary knowledge test (CVKT) were used to assess vocabulary acquisition. Results of statistical analyses revealed that while the text–picture–audio gloss type consistently resulted in better vocabulary learning and reading comprehension, the learning conditions varied in terms of their immediate and delayed effect on vocabulary and reading scores. This study suggests that learner performances across gloss types are condition specific and provides both pedagogical and theoretical implications. What is already known about this topic

• Electronic glosses foster reading comprehension and vocabulary acquisition.
• There are different positions about the effectiveness of form focused instruction in grammar, with the focus on forms approach having a higher acceptable rate in SLA. But, this issue has been rarely researched in vocabulary acquisition.

What this paper adds

• This study supports the complementary nature of dual annotations in vocabulary learning and reading comprehension.
• This study extends the issue of form focused instruction to vocabulary learning by comparing the incidental, intentional and incidental–intentional learning orientations.
• This study evaluates the interaction between the multiple gloss types and the learning orientations.

Implications for theory, policy or practice

• This study provides both pedagogical and theoretical implications.

     

Mr. Collins: A collaboratively constructed,inspectable student model for intelligent computer assisted language learning

This paper describes Mr. Collins, a student model for intelligent computer assisted language learning (ICALL), which is based on the results of empirical studies conducted in the target domain. Mr.Collins is constructed and updated through student/system collaboration. This collaborative approach to learner modelling aims both to promote student reflection through discussion of the student-model, and to provide more detailed and accurate information for the model. Due to his own contributions the student is less likely to regard the model with suspicion. Because the student model is the focus of the system, it must contain more information than is typically found in learner models. Therefore, in addition to domain knowledge and misconceptions, Mr. Collins also models learner confidence, background languages and learning strategies. The typical acquisition sequence for the target rules is explicitly modelled to provide an additional perspective from which the system may assess learner input.This is an extended version of a paper presented at PEG93.     

Contributions of Academic Language,Perspective Taking,and Complex Reasoning to Deep Reading Comprehension

ABSTRACT

Deep reading comprehension refers to the process required to succeed at tasks defined by the Common Core State Literacy Standards, as well as to achieve proficiency on the more challenging reading tasks in the Program for International Student Assessment (PISA) framework. The purpose of this study was to test the hypothesis that three skill domains not frequently attended to in instruction or in theories of reading comprehension—academic language, perspective taking, and complex reasoning—predict outcomes on an assessment of deep reading comprehension. The Global Integrated Scenario-based Assessment (GISA; O'Reilly, Weeks, Sabatini, Halderman, & Steinberg, 2014 O'Reilly T., Weeks, J., Sabatini, J., Halderman, L., & Steinberg, J. (2014). Designing reading comprehension assessments for reading interventions: How a theoretically motivated assessment can serve as an outcome measure. Educational Psychology Review, 26, 403–424. doi:10.1007/s10648-014-9269-z[Crossref], [Web of Science ®] , [Google Scholar]) is designed to reflect students' abilities to evaluate texts, integrate information from an array of texts, and use textual evidence to formulate a position, all features of deep reading comprehension. We tested the role of academic language, perspective taking, and complex reasoning in explaining variance in end-of-year GISA scores, controlling for beginning-of-year scores and student demographics. All three predictors explained small, but significant, amounts of additional variance. We suggest that these three skill domains deserve greater attention in theories of reading comprehension and in instruction.     

Episodic and individual effects of elementary students' optimal experience: An HLM study

The authors defined optimal experience as a functional state of a relatively high level of concentration, time distortion, satisfaction, and enjoyment (Csikszentmihalyi, 1992 Csikszentmihalyi, M. (1992). The flow experience and its significance for human psychology. In M. C. I. S. Csikszentmihalyi (Ed.), Optimal experience: Psychological studies of flow in consciousness. London, England: Cambridge University Press. [Google Scholar]) and collected data through the Day Reconstruction Method. In three random days, 147 fifth-grade students answered questionnaires for each school event in the previous day resulting repeated data from 2,288 episodes. Several hierarchical linear models were conducted. The authors found that elementary students perceived better quality of optimal experience during break time versus classes taught by activity, seatwork or lecture methods. Unexpectedly, more optimal experience was reported in the events when students perceived themselves as having high skill but low challenge, contradictory to the original expectation of skill–challenge balance. Four additional flow conditions were more effective than primary flow condition and instructional methods in predicting optimal experience. Finally, optimal experience varied much more across event-episodes than among individuals meaning that teachers have rooms to improve students' optimal experience in elementary school days.
