Coordinating principles and examples through analogy and self-explanation

Research on expertise suggests that a critical aspect of expert understanding is knowledge of the relations between domain principles and problem features. We investigated two instructional pathways hypothesized to facilitate students’ learning of these relations when studying worked examples. The first path is through self-explaining how worked examples instantiate domain principles and the second is through analogical comparison of worked examples. We compared both of these pathways to a third instructional path where students read worked examples and solved practice problems. Students in an introductory physics class were randomly assigned to one of three worked example conditions (reading, self-explanation, or analogy) when learning about rotational kinematics and then completed a set of problem solving and conceptual tests that measured near, intermediate, and far transfer. Students in the reading and self-explanation groups performed better than the analogy group on near transfer problems solved during the learning activities. However, this problem solving advantage was short lived as all three groups performed similarly on two intermediate transfer problems given at test. On the far transfer test, the self-explanation and analogy groups performed better than the reading group. These results are consistent with the idea that self-explanation and analogical comparison can facilitate conceptual learning without decrements to problem solving skills relative to a more traditional type of instruction in a classroom setting.     

Testing the instructional fit hypothesis: the case of self-explanation prompts

Cognitive science principles should have implications for the design of effective learning environments. The self-explanation principle was chosen for the current work because it has developed significantly over the last 20 years. Early formulations hypothesized that self-explanation facilitated inference generation to supply missing information about a concept or target skill, whereas later work hypothesized that self-explanation facilitated mental-model revision (Chi, Handbook of research on conceptual change, 2000). To better understand the complex relationship between prior knowledge, cognitive processing, and changes to a learner’s representation, two classes of self-explanation prompts (gap-filling and mental-model revision) were tested in the domain of physics problem solving. Prompts designed to focus the learner on gap-filling led to greater learning and a reduction in the amount of tutoring assistance required to solve physics problems. The results are interpreted as support for the instructional fit hypothesis—the idea that the efficacy of instruction is contingent on the match between the cognitive processing that the instruction elicits, how those processes modify the underlying knowledge representations for the task, and the utility of those representations for the task or problem.     

Finding the Best Types of Guidance for Constructing Self-Explanations of Subgoals in Programming

Subgoal learning, a technique used to break down problem solving into manageable pieces, has been used to promote retention and transfer in procedural domains, such as programming. The primary method of learning subgoals has been passive, and passive learning methods are typically less effective than constructive methods. To promote constructive methods of learning subgoals, we prompted learners to self-explain the subgoals of a problem-solving procedure. Self-explanation asks learners to make sense of new information based on prior knowledge and logical reasoning. Novices’ self-explanation is typically more effective when they receive guidance, because it helps them to focus on relevant information. In the present experimental study, the types of guidance that students received while self-explaining determined whether the constructive learning method was more effective than the passive method. Participants assigned to the constructive learning method performed best when they either received hints about the subgoals or received correct explanations as feedback, but not when they received both. These findings suggest that constructive learning of subgoals can further improve the benefits of subgoal learning when students receive only guidance that complements their construction of knowledge. This nuance is important for educators who engage their students in constructive learning and self-explanation.     

Examining the effects of combining self-explanation principles with an educational game on learning science concepts

Educational researchers have indicated that although computer games have the potential to promote students’ motivation and engagement, the work on how to design effective games that fulfil educational purposes is still in its infancy. This study aimed to examine how integration of self-explanation into a computer game affected primary schoolers’ acquisition of light and shadow concepts. The participants were randomly assigned to either an experimental group or a control group and played a computer game with or without self-explanation prompts individually as a treatment. Students’ conceptual understanding was evaluated through a pretest and a posttest administered right after the treatment. The results revealed that by controlling the pretest scores, students who played the game with self-explanation features did not outperform those who played the game without any prompts in the posttest. Further analyses of the experimental group students’ responses to the self-explanation prompts also indicated that the students with more correct responses to the prompts did not perform better than those with lower accuracy rates. The deficits in the use of self-explanation prompts are identified, and possible improvements to enhance the function of self-explanation in educational games are proposed.     

Headsprout® Early Reading for children with severe intellectual disabilities: a single blind randomised controlled trial

Research evaluating phonics reading programs for children with severe intellectual disabilities (ID) is limited. The current study investigated whether using an online reading program (Headsprout^® Early Reading; HER) as supplementary reading instruction for children with a severe ID leads to improvements in reading skills as compared to children not receiving this additional instruction. Fifty-five children from a special school were randomly allocated into the HER group or a waiting list control group. For six months, children in the intervention group received HER as supplementary instruction, whereas children in the control group received only ‘reading as usual’ teaching. Pre- and post-intervention tests on standardised reading measures were conducted. Analysis of data from outcome measures indicated that the HER group made improvements at post-intervention in comparison with the control group, with medium effect sizes on two domains from the main outcome measure. These results support the case for a larger research trial of HER for children with severe ID.     

Sequential effects of high and low instructional guidance on children’s acquisition of experimentation skills: Is it all in the timing?

We report the effect of different sequences of high vs low levels of instructional guidance on children’s immediate learning and long-term transfer of simple experimental design procedures and concepts, often called “CVS” (Control of Variables Strategy). Third-grade children (N = 57) received instruction in CVS via one of four possible orderings of high or low instructional guidance: high followed by high (HH), high followed by low (HL), low followed by high (LH), and low followed by low (LL). High guidance instruction consisted of a combination of direct instruction and inquiry questions, and low guidance included only inquiry questions. Contrary to the frequent claim that a high degree of instructional guidance leads to shallow learning and transfer, across a number of assessments—including a 5-month post-test—the HH group demonstrated a stronger understanding of CVS than the LL group. Moreover, we found no advantage for preceding high guidance with low guidance. We discuss our findings in relation to perspectives advocating “invention as preparation for future learning”, and the efficacy of “productive failure”.     

Embellishing Problem-Solving Examples with Deep Structure Information Facilitates Transfer

Appreciation of problem structure is critical to successful learning. Two experiments investigated effective ways of communicating problem structure in a computer-based learning environment and tested whether verbal instruction is necessary to specify solution steps, when deep structure is already embellished by instructional examples. Participants learned to solve algebra-like problems and then solved transfer problems that required adjustment of learned procedures. Experiment 1 demonstrated that verbal instruction helped learning by reducing learners' floundering, but its positive effect disappeared in the transfer. More importantly, students transferred better when they studied with examples that emphasized problem structure rather than solution procedure. Experiment 2 showed that verbal instruction was not necessarily more effective than nonverbal scaffolding to convey problem structure. Final understanding was determined by transparency of problem structure regardless of presence of verbal instruction. However, verbal instruction had a positive impact on learners by having them persist through the task, and optimal instructional choices were likely to differ depending on populations of learners.     

Assisting self-explanation prompts are more effective than open prompts when learning with multiple representations

Learning with multiple representations is usually employed in order to foster understanding. However, it also imposes high demands on the learners and often does not lead to the expected results, especially because the learners do not integrate the different representations. Thus, it is necessary to support the learners’ self-explanation activity, which concerns the integration and understanding of multiple representations. In the present experiment, we employed multi-representational worked-out examples and tested the effects of two types of self-explanation prompts as help procedures for integrating and understanding multiple representations. The participants (N = 62) learned about probability theory under three conditions: (a) open self-explanation prompts, (b) self-explanation prompts in an assistance-giving-assistance-withholding procedure (assisting self-explanation prompts), or (c) no prompts (control group). Both types of self-explanation prompts fostered procedural knowledge. This effect was mediated by self-explanations directed to domain principles. Conceptual knowledge was particularly fostered by assisting self-explanation prompts which was mediated by self-explanations on the rationale of a principle. Thus, for enhancing high-quality self-explanations and both procedural knowledge and conceptual understanding, we conclude that assisting self-explanation prompts should be provided. We call this the assisting self-explanation prompt effect which refers to the elicitation of high-quality self-explanations and the acquisition of deep understanding.     

The Cognitive and Academic Benefits of Music to Children: Facts and fiction

There is considerable interest in the potential non‐musical cognitive and academic benefits of music listening and instruction to children. This report describes three lines of research relevant to this issue, namely, the effects of: (1) focused music listening on subsequent task performance (the Mozart effect); (2) music instruction; and (3) background music listening. Research suggests that while Mozart effect studies have attracted considerable media attention, the effect cannot be reliably demonstrated in children. In contrast, music instruction confers consistent benefits for spatiotemporal reasoning skills; however, improvements in associated academic domains, such as arithmetic, have not been reliably shown. Finally, background music may calm and focus children with special education needs, thereby enhancing learning. Additional research is required to determine whether this effect is evident in normal populations. Overall, evidence for the non‐musical benefits of music listening and instruction is limited. The inherent value of music and music education should not be overlooked by narrowly focusing on cognitive and academic outcomes.     

Instruction-first and problem-solving-first approaches: alternative pathways to learning complex tasks

According to cognitive load theory, using worked examples is an effective and efficient instructional strategy for initial cognitive skill acquisition for novice learners, as it reduces cognitive load and frees up cognitive resources to build task competence. Contrary to this, productive failure (as well as invention learning, desirable difficulties and other problem-solving-first) frameworks suggest that scaffolded problem-solving activities (a generation phase) preceding explicit instruction enhance learners’ performance. The reported experimental study investigated the effectiveness of different levels of instructional guidance provided to students during the learning phase preceding explicit instruction in standard solution procedures in enhancing students’ engagement and transfer problem-solving skills. Specifically, the study compared partially-guided or unguided attempts at generating problem solutions as opposed to comprehensive guidance, in the form of a worked example. Levels of experienced cognitive load and learner motivation were evaluated in addition to delayed post-test performance scores. There were no differences between the three groups on the transfer post-test outcomes, even though the condition with fully-guided worked examples prior to the explicit instruction expectedly reduced cognitive load relative to the conditions without such guidance. There were also differences between the conditions on some sub-dimensions of the motivation scale. In general, the findings indicate that similar overall outcomes (delayed transfer performance) could be achieved by different sequences of instructional tasks aimed at achieving different sets of specific goals.     

Comparing Effects of Instruction on Word Meaning and Word Form on Early Literacy Abilities in Kindergarten

Research Findings: The present study compared effects of explicit instruction on and practice with the phonological form of words (form-focused instruction) versus explicit instruction on and practice with the meaning of words (meaning-focused instruction). Instruction was given via interactive storybook reading in the kindergarten classroom of children learning Dutch. We asked whether the 2 types of instruction had different effects on vocabulary development and 2 precursors of reading ability—phonological awareness and letter knowledge—and we examined effects on these measures of the ability to learn new words with minimal acoustic-phonetic differences. Learners showed similar receptive target-word vocabulary gain after both types of instruction, but learners who received form-focused vocabulary instruction showed more gain in semantic knowledge of target vocabulary, phonological awareness, and letter knowledge than learners who received meaning-focused vocabulary instruction. Level of ability to learn pairs of words with minimal acoustic-phonetic differences predicted gain in semantic knowledge of target vocabulary and in letter knowledge in the form-focused instruction group only. Practice or Policy: A focus on the form of words during instruction appears to have benefits for young children learning vocabulary.     

Preventing retention: First grade classroom instruction and student characteristics

Retention is a frequently used strategy to support children who are struggling academically. However, the strategy is costly, and research findings with regard to positive outcomes are mixed. This study examined whether efficacious reading instruction might reduce rates of retention in first grade. We also evaluated the reading instruction the students received compared with children with similar reading and vocabulary skills who were not retained. Additionally, we examined the impact students' self‐regulation may have on grade retention. Findings reveal that it was significantly less likely for students to be retained at the end of first grade if their teacher was implementing more efficacious reading instruction. Moreover, there were substantial differences in the literacy instruction provided for children who were and were not retained. Finally, students in the efficacious reading condition who were retained exhibited significantly weaker self‐regulation skills than did their matched‐promoted peers. © 2012 Wiley Periodicals, Inc.     

Interactive Example-Based Learning Environments: Using Interactive Elements to Encourage Effective Processing of Worked Examples

This review describes parts of our research program on example-based learning that relates to recent efforts to incorporate interactive elements into learning environments designed to support learning from worked-out examples. Since most learners spontaneously study or process examples in a very passive or superficial manner, this review focuses on how a variety of specific interactive elements in example-based leaning environments are capable of encouraging learners to actively process the examples. The review begins with an overview of the literature on worked examples and the associated self-explanation, which is important given that the quality of self-explanation is a major factor in determining whether learners benefit from studying examples. The review notes that example-based learning environments tend to be effective but often promote passive processing. It then highlights the strengths and limitations of three types interactivity introduced to example-based learning environments. The review concludes with a discussion of the role that these interactive elements play in these learning environments.     

A combined approach to strengthen children’s scientific thinking: direct instruction on scientific reasoning and training of teacher’s verbal support

Inquiry-based lessons have been demonstrated to improve children’s scientific thinking (i.e. reasoning abilities and domain-specific knowledge). Although empirical evidence shows that inquiry-based learning requires instruction, research comes from two approaches that have not been bridged yet: direct instruction of scientific reasoning and teacher training of verbal support. We investigated how these two types of instruction separately or combined strengthened children’s scientific thinking by comparing four conditions: baseline, direct instruction, verbal support, and a combined approach. Effectiveness of an inquiry-based lesson series on scientific reasoning abilities, vocabulary, and domain-specific knowledge (near and far transfer) were studied among 301 fourth graders. Results showed that both approaches strengthened different components of scientific reasoning abilities, and that a combination of instructions was most effective for scientific reasoning abilities, vocabulary, and domain-specific knowledge. Domain-specific knowledge acquisition was strengthened only when both instructions were provided. It can thus be concluded that each type of instruction has unique contributions to children’s science learning and that these instructions complement each other. Our study thus showed that inquiry-based lesson series when preceded by direct instruction of scientific reasoning and scaffolded with verbal support are most effective.     

Some observations on beginning reading instruction

In this article, I review findings from 25 years of my own reading research that bear on the issue of skill-oriented versus holistic approaches to beginning reading. Several studies suggested that successful beginning readers demonstrate early development of word-recognition skills. These studies also indicated that both more and less successful readers make extensive use of contextual information when reading. Two experimental studies suggested that increased instructional and curriculum support for word recognition result in improvements in reading skill compared to whole-language instruction. In conclusion, I suggest that it is a mistake to treat systematic instruction of word-recognition skills as an alternative to instruction that emphasizes reading "authentic" texts and building language comprehension. Both word-recognition skills and building comprehension should be part of a reading program aimed at creating effective independent readers.     

Intensive remedial instruction for children with severe reading disabilities: immediate and long-term outcomes from two instructional approaches

Sixty children with severe reading disabilities were randomly assigned to two instructional programs that incorporated principles of effective instruction but differed in depth and extent of instruction in phonemic awareness and phonemic decoding skills. All children received 67.5 hours of one-to-one instruction in two 50-minute sessions per day for 8 weeks. Both instructional programs produced very large improvements in generalized reading skills that were stable over a 2-year follow-up period. When compared to the growth in broad reading ability that the participants made during their previous 16 months in learning disabilities resource rooms, their growth during the intervention produced effect sizes of 4.4 for one of the interventions and 3.9 for the other. Although the children's average scores on reading accuracy and comprehension were in the average range at the end of the follow-up period, measures of reading rate showed continued severe impairment for most of the children. Within 1 year following the intervention, 40% of the children were found to be no longer in need of special education services. The two methods of instruction were not differentially effective for children who entered the study with different levels of phonological ability, and the best overall predictors of long-term growth were resource room teacher ratings of attention/behavior, general verbal ability, and prior levels of component reading skills.     

Improving critical thinking: Effects of dispositions and instructions on economics students' reasoning skills

This experiment investigated the impact of critical thinking dispositions and instructions on economics students' performance on reasoning skills. Participants (N = 183) were exposed to one of four conditions: critical thinking instruction, critical thinking instruction with self-explanation prompts during subsequent practice, critical thinking instruction with activation prompts during subsequent practice, or no critical thinking instruction or prompts (control). In all conditions, practice was a within-subjects factor, some task categories present in the test were practiced on a business case, others were not. Participants in the instruction conditions significantly outperformed participants in the control condition on the immediate and delayed post-test, but only on the practiced task categories – with the exception of the self-explanations condition, which also showed a better performance than the control condition on not-practiced categories, though only on the immediate post-test. Dispositions (i.e., Actively Open-minded Thinking and Need for Cognition) predicted reasoning skills at pre-test but did not interact with instructions on post-tests performances.     

Critical Elements of Classroom and Small-Group Instruction Promote Reading Success in All Children

The components of effective reading instruction are the same whether the focus is prevention or intervention: phonemic awareness and phonemic decoding skills, fluency in word recognition and text processing, construction of meaning, vocabulary, spelling, and writing. Findings from evidence-based research show dramatic reductions in the incidence of reading failure when explicit instruction in these components is provided by the classroom teacher. To address the needs of children most at risk of reading failure, the same instructional components are relevant but they need to be made more explicit and comprehensive, more intensive, and more supportive in small-group or one-on-one formats. The argument is made that by coordinating research evidence from effective classroom reading instruction with effective small-group and one-on-one reading instruction we can meet the literacy needs of all children.     

Learning from direct instruction: Best prepared by several self-regulated or guided invention activities?

Learning from direct instruction can be enhanced by preparatory invention tasks: students invent an index that allows to differentiate a set of cases regarding important aspects (self-regulated). However, contradictory results have been found. As self-regulated activities often need practice, we tested whether the contradictory findings persist when students can practice inventing. We randomly assigned 99 eighth-grade students to two conditions (independent variable): they either invented twice (self-regulated; n = 49) or worked through worked solutions of the two tasks (guided; n = 50) before learning about ratios in physics from a lecture. Extraneous load, deep-structure recall, knowledge-gap perception, and self-efficacy were potential mediators. Transfer was the dependent measure. Guidance led to less extraneous load. However, self-regulation led to higher transfer because the students devoted more attention to the deep structure of the preparation tasks. Our findings suggest that—given some practice—self-regulated outperforms guided preparation for learning from direct instruction.     

Assessing more than you teach: the difficult case of transfer

We conducted two case studies to evaluate the effectiveness of individualized remedial reading instruction linked to direct measures of student learning and transfer. The participants were two first grade children at serious risk of reading failure. The instruction targeted decoding of one syllable short vowel words and first emphasized onset-rimes and then phoneme manipulation. Forty words organized into 10 rime patterns were targeted for instruction. Probes consisting of all the instructional words were administered before each instructional session to monitor student progress. We also administered transfer probes to determine if the children could apply their knowledge more broadly. Instruction with onset-rime units yielded excellent maintenance and near transfer (novel words containing instructed rimes) but not far transfer (novel words derived from uninstructed rimes). The instructional change to phoneme manipulation yielded better far transfer for one of the two children. We consider the importance of administering measures that assess more than what is taught to get an accurate portrait of children’s responsiveness to instruction.
