When Sociocognitive Transaction among Peers Fails: The Case of Misconceptions in Science

The effect ofsociocognitive transaction among peers on cognitive change was analyzed. Transaction concerned the concept of speed applied to 2 problems: a Piagetian problem and a parallel problem evoking a misconception. The effect of transaction, intended to evoke inter- and intrapersonal conflicts, was compared to two other treatments: taking a multiple choice test aimed to raise intrapersonal conflict and no intervention. A total of 360 sixth, eighth, and tenth graders participated. Following treatments, subjects mainly progressed on the Piagetian problem and mainly regressed on the problem evoking the misconception. Transaction had a beneficial effect on the former problem, encouraging progress and discouraging regression relatively to other treatments. It had a bidirectional effect on the latter problem, encouraging both progress and regression. Cognitive change following transaction was related to level of reasoning on speed during transaction. Inter- and intrapersonal conflicts evoked by transaction resulted in different changes in the 2 problems: Interpersonal conflict increased intrapersonal conflict on both, but the degree of intrapersonal conflict was related to change on the latter problem only, with greater conflict evoking greater change, mainly regressive. Results cast doubt on Piagetian assumptions concerning the role of conflict in cognitive development.     

Learning from Worked-Out Examples: The Effects of Example Variability and Elicited Self-Explanations

It was investigated to what extent example variability and the elicitation of sophisticated self-explanations foster the acquisition of transferable knowledge by learning from worked-out examples. In addition, it was asked whether the effects of these factors are moderated by the learners' levels of prior topic knowledge. To this end, we had 56 apprentices from a bank learn calculation of compound interest and real interest. They were randomly assigned to the four conditions of a 2 × 2-factorial design (factor 1: uniform vs. multiple examples; factor 2: spontaneous vs. elicited self-explanations). The learning results were measured by a post-test comprising near-transfer problems and far-transfer problems. It was found that the acquisition of transferable knowledge can be supported by eliciting self-explanations. In the case of near transfer, especially learners with low levels of prior topic knowledge profited from the elicitation procedure. On the whole, the findings underline the “causal” relevance of the quality of self-explanations for knowledge acquisition by learning from worked-out examples. The assumption that multiple examples foster transfer performance, at least when sophisticated self-explanations are elicited, was not supported.     

An Understanding of (Mis)Understanders: Exploring the Underlying Mechanisms of Concept Learning Using Functional Magnetic Resonance Imaging

Obtaining adequate understanding of scientific concepts is considered challenging due to learners' misconceptions about natural phenomena. Misconceptions may coexist with scientific knowledge in the brain. Therefore, misconceptions must be cognitively inhibited in order to select the scientific knowledge. There is, however, lack of substantial neuroscientific evidence supporting this hypothesis. In this study, we sought for this evidence by investigating medical students who solved a cardiovascular conceptual problem in a magnetic resonance imaging scanner. Brain activation was compared between understanders who had the scientific knowledge, and misunderstanders who held a misconception. No significant activation was found in brain areas related to cognitive inhibition in understanders compared with misunderstanders. Therefore, we could not confirm the idea that cognitive inhibition is involved in overcoming a misconception. Instead, we found that the putamen was significantly activated in misunderstanders compared with understanders, suggesting a role for episodic memory in learners holding a misconception.     

Conceptual Resources in Self‐developed Explanatory Models: The importance of integrating conscious and intuitive knowledge

This study explores the spontaneous explanatory models children construct, critique, and revise in the context of tasks in which children need to predict, observe, and explain phenomena involving magnetism. It further investigates what conceptual resources students use, and in what ways they use them, to construct explanatory models, and the obstacles preventing them from constructing a useful explanatory model. Our findings indicate that several of the children were able to construct explanatory models. However, of the six children interviewed multiple times (three third‐graders and three sixth‐graders), only one was consistently able to critique and revise her models to arrive at a consistent, coherent, and sophisticated explanatory model. Connecting intuitive knowledge and abstract knowledge was important in her construction of a coherent and sophisticated explanatory model. Students who relied only on intuitive knowledge constructed tentative and non‐sophisticated explanatory models. Students who relied only on verbal‐symbolic knowledge at an abstract level without connection with their intuition also did not construct coherent and sophisticated models. These results indicate that instruction should help students to become meta‐conceptually aware and connect their verbal‐symbolic knowledge and intuition in order to construct explanatory models to make sense of abstract scientific knowledge.     

A SELECTED LIST OF TEXTBOOKS AVAILABLE FOR USE IN THE GRADED SUNDAY SCHOOL

This study investigates Suhrawardi's epistemological and philosophical point of view in order to analyze and elicit its educational outcomes. His philosophy, which can be called eclectic philosophy (involving intellect and intuition), regularly proposes a different philosophical system with intuitionist outlook. It is the combination of two philosophical and mystical views, namely Aristotle's logical reasoning and Plato's mysticism. Suhrawardi has rather suggested this belief in the field of acquiring knowledge by humans that depends on three levels of knowledge, namely intuitive knowledge (using senses), knowledge via observation (mystical intuition), and illuminated knowledge. The third level of knowledge leads a human to the verity of knowledge. Therefore, this view about knowledge, and process of this knowledge acquisition, will have educational implications such as aims, principles, and teaching–learning methodology.     

Misconceptions About Human Rights and Women’s Rights in Islam

This paper aims to clarify three current misconceptions about the Islamic faith and issues of human rights and women’s rights in the West. The first misconception is that Muslims are terrorists because they believe in Jihad. It is factually the case that Islamic teachings stress the value of peace and prosperity for all human beings. The second misconception is that Muslims prohibit scientific knowledge and only aim to seek religious knowledge. To the contrary, Qur’an emphasizes that the opportunity to seek all forms of knowledge is a human right and responsibility of all Muslims. The third misconception and perhaps, the most controversial, is that Islam oppresses women. In reality, Islam offers women the right to make their own choices in the areas of education, business, and property, to name a few. By sharing my own experiential narrative as a Muslim born woman and that of a Canadian women who converted to Islam, I can actually see the similarities between human rights in Islam and the United Nation’s Universal Declaration of Human Rights (1948).     

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.     

Knowledge Integration in Science Learning: Tracking Students' Knowledge Development and Skill Acquisition with Cognitive Diagnosis Models

In scientific literacy, knowledge integration (KI) is a scaffolding-based theory to assist students' scientific inquiry learning. To drive students to be self-directed, many courses have been developed based on KI framework. However, few efforts have been made to evaluate the outcome of students' learning under KI instruction. Moreover, finer-grained information has been pursued to better understand students' learning and how it progresses over time. In this article, a normative procedure of building and choosing cognitive diagnosis models (CDMs) and attribute hierarchies was formulated under KI theory. We examined the utility of CDMs for evaluating students' knowledge status in KI learning. The results of the data analysis confirmed an intuitive assumption of the hierarchical structure of KI components. Furthermore, analysis of pre- and posttests using a higher-order, hidden Markov model tracked students' skill acquisition while integrating knowledge. Results showed that students make significant progress after using the web-based inquiry science environment (WISE) platform.

Spontaneous recovery evoked by a nonreinforced stimulus

Pigeons (nine groups of seven) were given one acquisition session of 20 trials. The following day their responding was extinguished, and after a 30-min rest period they were tested for residual response strength. The groups differed with respect to (1) whether a distinctive stimulus was presented during acquisition on the first trial, the 15th trial, or not at all, (2) whether or not responses to the distinctive stimulus were reinforced, and (3) whether a distinctive stimulus, a standard stimulus, or a completely novel stimulus was presented on the test trial. Results supported the position that a stimulus associated with the onset of an acquisition session, but not with the extinction session, evokes greater response strength on a spontaneous recovery test trial than do other stimuli in the acquisition session. This holds true even if responses to this stimulus are never reinforced. In addition, it was found that, unlike a previous study that invoked five daily acquisition sessions, pigeons did not demonstrate increased responding to a novel stimulus.     

Cognitive conflict and intuitive rules

This paper is a part of an extensive project on the role of intuitive rules in science and mathematics education. First, we described the effects of two intuitive rules ‐‐ ‘Everything comes to an end’ and ‘Everything can be divided’ ‐‐ on seventh to twelfth grade students’ responses to successive division tasks related to mathematical and physical objects. Then, we studied the effect of an intervention, which provided students with two contradictory statements, one in line with students’ intuitive response, the other contradicting it, on their responses to various successive division tasks. It was found that this conflict‐based intervention did not improve students’ ability to differentiate between successive division processes related to mathematical objects and those related to material ones. These results reconfirmed that intuitive rules are stable and resistant to change. Finally, this paper raised the need for additional research related to the relationship between intuitive rules and formal knowledge.     

Summation of undetected excitation following extinction of the CER

The effects of compounding two conditioned stimuli (CSs), each of which had been extinguished to varying degrees in different groups of rats given identical acquisition training, was examined within the conditioned emotional response paradigm. Greater suppression to the compound than to the individual CSs was observed following 6, 12, 48, 72, and 96 stimulus extinction trials, although after only 12 extinction trials suppression to the individual stimuli was no longer observed. The amount of compound suppression decreased progressively as the number of extinction trials increased until, after 120 extinction trials on each stimulus, the compound no longer elicited observable suppression. Control group data indicated that the observed summation effect could not be attributed to disinhibition. The possible role of the summation of undetected excitation in studies examining configurai conditioning, avoidance conditioning and reinstatement is discussed briefly.     

Representing and Meaning in History and in Classrooms: Developing Symbols and Conceptual Organizations of Free-Fall Motion

This study offers a psychological role that external representations can play in theprocess of refining intuitive ideas into scientific knowledge. An argument for thisrole is presented first through historical analysis of Galileo's ramp experiments andthen through documentation of an innovative sixth-grade classroom activity. In bothof these cases, engagement with and refinement of external representations of motionwere central supports to conceptual and empirical meaning making. An instructionalapproach that uses representation activities to support student development of theirown conceptual and empirical approaches to a phenomenon stands in contrast to theprevailing trend in science curricula, which focuses exclusively on content acquisition.     

A fading procedure facilitates the maintenance of observing responses when the more valued stimulus is not produced

Pigeons served in two experiments in which responding on an observing key converted a two-component mixed schedule to the corresponding multiple schedule of reinforcement. Presentation of the stimulus correlated with the more valued component was faded out (probabilistically) over sessions, so that ultimately an observing response produced only the stimulus correlated with the less valued component. Observing was well maintained after a fading procedure when a stimulus was produced by a single response, regardless of whether the less valued stimulus was associated with food or with extinction (Experiment 1). However, observing was not well maintained after a fading procedure when a stimulus was produced according to an intermittent schedule (Experiment 2). Taken together, the results of the two experiments suggest that the absence of an exteroceptive stimulus change after a single response may become discriminative in its own right for the more valued component, and that the fading procedure is an effective means of promoting this discrimination. However, if observing responses produce a stimulus change according to an intermittent schedule, then the absence of a stimulus change after a response is correlated with both components. Under these conditions, the absence of stimulus change is not discriminative for either component, even with fading, and observing is not maintained.     

A Comparison of the Effects of Fluency Training and Accuracy Training on Application and Retention

The effects of fluency training on the acquisition and retention of a composite skill were compared with those of training to accuracy only. Participants were 30 college students, and the task was a stimulus equivalence task, similar to the one used by Binder (1995) in earlier assessments. Participants learned associations between Hebrew symbols and nonsense syllables and between nonsense syllables and Arabic numerals. Immediately after training and every 2 or 4 weeks for 16 weeks, they were tested on a composite task that required both associations. Retention of the original component associations was also assessed after 4 months. With respect to the composite skill, fluency training resulted in: a) higher response rates immediately after training and across the 16 weeks; b) better accuracy 4 and 16 weeks after training; and c) less deterioration of accuracy after 16 weeks. Effects on the component skills were similar. The results document that for skilled adult learners, fluency training can aid the acquisition of a higher level skill and increase the retention of accuracy for both the component and composite skills.     

Knowledge transfer in the context of refutation texts

In this study, we examined the conditions under which readers are able to transfer revised knowledge as a result of reading refutation texts (i.e. texts that explicitly state and refute a misconception). Across three experiments, participants read refutation texts that addressed socioscientific and nonsocioscientific issues as well as transfer texts that were designed to reactivate the misconceptions addressed in refutation texts. In Experiments 1 and 2, the results indicate that reading a refutation text reduces interference from the misconception as participants read the transfer texts in close temporal distance, even when the misconception is reactivated. In Experiment 3, the results indicate that participants reading refutation texts could not transfer revised knowledge when the temporal distance between refutation texts and transfer texts increased. Students’ performance on pretest and posttest questionnaires also suggest that reading the refutation texts facilitated knowledge revision prior to transfer. We discuss the findings in the context of the Knowledge Revision Components Framework.     

Integration of cardiac responses to serial stimuli after Pavlovian conditioning in rats

The expression of cardiac responses to sequences of two sounds was studied in restrained rats following discriminative trace or delay conditioning. Stimuli paired with a tail shock 10 sec later (CS1) elicited conditioned bradycardia. Unpaired or neutral stimuli (CS0) elicited mostly tachycardia. Rats did not learn to suppress responding to nonreinforced sequences with an interval of 6 sec between sounds. Responses to the second stimulus were significantly augmented following a CS1 stimulus, but not following a CS0 stimulus. Real-time summation of simple responses provided a more complete and quantitative prediction of dual responses than did resetting or facilitation. These results extend the time range over which summation may be observed from less than 2 sec to at least 16 sec. They appear to be inconsistent with models involving competition between unitary representations of stimuli in short-term memory and suggest the existence of multiple stimulus traces with independent time courses.     

A Longitudinal Study of Physics Students’ Conceptions of Force in Pre-service Training for High School Teachers

Do physics students in pre-service training to be high-school teachers hold the accepted scientific views that will eventually allow them to plan and implement instructional strategies, which, in turn, will lead their future students to achieve a scientific concept of feree? The results of a longitudinal study dealing with this issue will be discussed in this paper. The most important findings of this study can be summarised as follows. Physics students in pre-service training for high school teachers: (1) mostly do not succeed in abandoning their Aristotelian ‘impetus’ misconception; (2) have difficulties in recognising reaction as a force; (3) are rather ambivalent when referring to the necessity of the forces to be balanced in static situations; (4) hold, to a great extent, the concept that an initial force exerted on an object keeps it going and gradually lessens--the ‘fading-away’ concept; (5) hold, to a great extent, the concept that a force (inertia), resisting a push, acts on moving objects; (6) tend to return in 4th year in college to intuitive views of force, rather than holding the accepted scientific concept.     

Refutation texts: Implying the refutation of a scientific misconception can facilitate knowledge revision

Refutation texts facilitate knowledge revision by placing science misconceptions in the foreground. However, in some situations, repeating incorrect information can work against the desired goal of correcting misconceptions, or can spread misinformation to new audiences. Thus, our goal was to examine whether merely implying the existence of a misconception, without explicitly stating the incorrect information, is sufficient to facilitate knowledge revision from a text. Undergraduate participants who expressed a common physics misconception read one of three passages about the issue, including a correct explanation of the situation. The passages differed in whether the refutation of the misconception was explicitly stated, implied by a warning phrase, or not referred to at all. We found that participants were less likely to express the misconception when they were questioned about the topic after reading the passage with the explicit refutation or with the warning phrase. Furthermore, the current results indicate that refutations of misconceptions can influence knowledge revision in ways that extended beyond the details of the original learning episode, even when they are only implied by a warning phrase. However, it remains unclear whether implied refutations of misconceptions can endure across a delay in time. These findings have potential implications for optimizing science texts to effectively address misconceptions.
