The effect of causal diagrams on text learning

We examined the effect of studying a causal diagram on comprehension of causal relationships from an expository science text. A causal diagram is a type of visual display that explicitly represents cause-effect relationships. In Experiment 1, readers between conditions did not differ with respect to memory for main ideas, but the readers who studied the causal diagram while reading the text understood better the five causal sequences in the text even when study time was controlled. Participants in Experiment 2 studied only the causal diagram or only the text. There were no differences in memory for main ideas or the causal sequences between these groups. Results indicate that causal diagrams are not merely redundant with text and that causal diagrams affect understanding of causal relationships in the absence of a text. These findings supported the causal explication hypothesis, which states that causal diagrams improve comprehension by explicitly representing the implicit causal structure of the text in a visual format.     

Worked examples with errors: when self-explanation prompts hinder learning of teachers diagnostic competences on problem-based learning

To diagnose classroom situations is crucial for teachers’ everyday practice. The approach of worked examples with errors seems promising to support the diagnosis of classroom situations in student teachers (Stark et al. in Learn Instr 21(1):22–33, 2011). To enhance that approach, error-explanation prompts and an adaptable feedback method to help the learner realize why an error happened and how to prevent a recurrence might be beneficial. In this empirical study, we investigated whether error-explanation prompts and adaptable feedback can facilitate diagnostic competences. N = 108 student teachers took part in a 2 × 2 factorial design (with and without error-explanation prompts as well as with and without adaptable feedback). Error-explanation prompts had a positive effect on declarative-conceptual knowledge if combined with adaptable feedback. Student teachers might have realized a lack of basic concepts and focused their attention on the declarative-conceptual knowledge in the feedback. Contrary to our expectations, however, error-explanation prompts hindered rather than facilitated learning of practical diagnostic knowledge.     

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.     

Emotional factors of causal coherence in text comprehension

The current study tested the effects of positive and negative emotion at the beginning and end of texts, as well as the consistency in valence throughout a text on readers’ response choice to items on a multiple-choice reading comprehension assessment. Multinomial logistic regressions were performed on 1,161 college participants’ assessment responses to test whether emotion in narrative and informational text items significantly predicted which distractor response options readers chose in comparison to the correct response option. Overall, consistent emotion throughout text and positive and negative emotion at the beginning and end of text were significant predictors of readers’ response choices. The results are discussed in terms of emotion being an indicator of readers’ causal processing. Specifically, findings provide a better understanding of how emotional features in narrative and informational texts may influence how readers develop causal coherence and comprehension during reading. This understanding could also help inform the development of instructional tools that encourage readers to focus on aspects of text (i.e., emotion) which could, in turn, help improve comprehension for readers who struggle.     

The impact of media multitasking on learning

While multitasking is not a new concept, it has received increasing attention in recent years with the development of new media and technologies. Recent trends appear to suggest that multitasking is on the rise among the younger generation. The purpose of the study is to determine if students obtain more or less information in multitasking conditions. We examined the relationships of multitasking to attention, cognitive load and media with 130 college student participants. In this study, participants were given a timed (16 minutes) reading comprehension test in three conditions: Silence (only reading), Background multitasking (reading with a non-tested video shown simultaneously), and Test multitasking (reading with a tested video shown simultaneously) conditions. Our findings indicated that: (1) participants in the Background condition performed as well as those in the Silence condition, and (2) when participants were tested on their video comprehension, the group in the Test condition performed significantly better than the group in the Background condition. The results of this study suggest that cognitive load plays an important role in determining how much information is retained when students perform more than one task at a time.     

The introduction of text conventions and its impact on teaching literacy

The introduction of text conventions, such as word separation, the separation of letter and background and the lower‐case letter are appraised with respect to their contribution to literacy instruction. The change in the visual appearance of the graphic word over time led to the assignment of secondary status to spelling and low appreciation of the role of phonology, due to the disappearance of audible speech in skilled reading. Since the two major literacy programmes, whole language and phonics, are based on two different stages of reading, both programmes complement each other. Whole language represents the skilled stage of reading, given its reliance on the graphic word, whereas phonics represents the unskilled stage, owing to its emphasis on the intermediatory role of phonological processing in word recognition. Neither literacy programme offers instruction in the integration of letters in a verbally recoded form with the explicit goal of the creation of word gestalts in the course of literacy acquisition.     

Transforming text for distance learning

This article is intended to help those who wish to transform existing text into good teaching material for use in distance learning. It contains a number of checklists to help transformers in their work and a number of examples of transformed materials to illustrate some of the possibilities.
The extent to which existing materials might need to be changed in order to produce good teaching materials will depend on the quality of the materials provided. However, although major changes may be considered desirable, they may not always be acceptable to all those concerned with the development of the materials. The article discusses factors that need to be taken into account in determining both the desirability and feasibility of possible changes.     

The impact of computer-mediated interaction on distance learning

Distance‐learning courses were classified with regard to their use of computer‐mediated interaction and the degree to which such interaction was integrated into the curriculum and the assessment regime. This produced four groups of courses varying according to their use of interaction and integration. The impact of interaction and integration was investigated in terms of their effects on students' performance, their perceptions of academic quality and their approaches to studying. In all three respects, variations within the groups of courses proved to be more important than variations between the groups. Interpretation of these results suggests that the adoption of interactive environments within computer‐mediated learning may not be enough in itself to lead to positive learning outcomes. We found no evidence for this assumption in terms of students' completion rates, pass rates, grades, perceptions of the quality of their courses or approaches to studying. Large variations in the measured indicators were found between courses, and these appeared to be largely independent of the effects of interaction and integration. Courses may differ markedly with regard to how they make use of computer‐mediated interaction and how this is integrated into the curriculum and the assessment regime. A case study approach is suggested as being more likely to identify the impact of specific designs based on computer‐mediated interaction and to bring together the diverse student responses arising from the use of such interaction in their studies.

The impact of higher education on lifelong learning

The UK’s National Adult Learning Survey has emphasised that graduates are more likely than other groups of people to engage in further learning and to be motivated by the intrinsic nature of the subject matter. However, beyond this we know relatively little about the learning of graduates as a specific group. In particular, we know very little about how experiences of higher education affect attitudes towards learning in the years after graduation. To start to redress this gap, this paper draws on in‐depth interviews with 90 graduates from six different UK higher education institutions, five years after they completed their first degree. It argues that, in the case of many of these young adults, the influence of higher education on further learning was exerted at three levels in relation to: the process of learning; the construction of learner identities; and understandings of the relationship between learning and the wider world.     

The impact of elaborated feedback on text comprehension within a computer-based assessment

We investigated what impact elaborated feedback has on sixth graders' deep-level comprehension of texts within a computer-based assessment. Experiment 1 (N = 566) focused on the contents of computer-provided elaborated feedback (i.e. inference-prompts, error explanations, or monitoring-prompt) using a control-group design. Results showed that none of the feedback treatments had an effect on performance. This appeared to result from participants' low commitment to processing the feedback. Experiment 2 (N = 251) focused on the feedback presentation type by varying computer-mediated and person-mediated inference-prompts within a control-group design. Results showed that only the person-mediated inference-prompts had significant effects on performance with respect to the correction of initially false answers to comprehension questions and the performance on subsequent test questions. Findings of both experiments indicate the impact of inference-prompts on text comprehension within performance assessments, highlighting the need to explicitly account for motivational issues in feedback interventions on higher-order reading processes.     

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.     

Space matters: The impact of formal learning environments on student learning

The objective of this research is to identify the relationship between formal learning spaces and student learning outcomes. Using a quasi‐experimental design, researchers partnered with an instructor who taught identical sections of the same course in two radically different formal learning environments to isolate the impact of the physical environment on student learning. The results of the study reveal that, holding all factors excepting the learning spaces constant, students taking the course in a technologically enhanced environment conducive to active learning techniques outperformed their peers who were taking the same course in a more traditional classroom setting. The evidence suggests strongly that technologically enhanced learning environments, independent of all other factors, have a significant and positive impact on student learning.     

Influence of text structure on learning counterintuitive physics concepts

The purpose of this study was to explore the influences of text structure on students' conceptual change. Case studies were conducted of three sections of physics (Physical World, Physics, and Honors Physics) for 8 months of an academic year. Qualitative data (including observation field notes, interviews, videotapes, audiotapes, and questionnaires) were analyzed from the perspective of grounded theory by constant comparison through the framework of social constructivism. Results showed that individuals used refutational text to change their alternative conceptions, find support for their scientific preconceptions, gain the language necessary to discuss their ideas, and acquire new concepts. We also found instances, however, when students ignored the text and persisted with their alternative conception, or when students found support for their nonscientific ideas from refutational text. In these cases, we found that either the refutation was not direct enough to be effective, or students' reading strategies were insufficient to facilitate conceptual change. In investigating the power of refutational text, we found that refutational text does cause cognitive conflict. We also discovered that while cognitive conflict may be necessary for conceptual change to occur, it is not sufficient. Although refutational text is effective on the average for groups of students, it will need to be supplemented by discussion for individuals. J Res Sci Teach 34: 701–719, 1997.     

Evaluating the effects of analogy enriched text on the learning of science: The importance of learning indexes

Research has shown that differences in the prior knowledge of the participants and in the learning indexes adopted can explain why some studies show positive learning effects of analogy enriched text while others do not. In the present studies, these two factors were combined into one through the construction of a learning index that measured incremental positive changes in the participants' prior knowledge after reading an analogy enriched or no analogy text. A second learning index was also used to evaluate whether the participants created well-formed conceptual models after reading the science text. These learning indexes were used in two studies in which the effects of analogy enriched versus no analogy text were compared on the learning of the scientific explanations of the day/night cycle and of the seasons. The participants were 3rd and 5th graders in the first study and 6th graders and college students in the other. Although only few of the participants learned the correct scientific explanation, those who read the analogy enriched text produced more incremental positive changes in their pretest explanations at posttest and delayed test and created more well-formed conceptual models close to the scientific one than those who read the no analogy text. They also recalled more information and created fewer invalid inferences in their recalls. The results indicate that analogies can be used without reservation to facilitate the learning of science and have broader implications about how to evaluate the learning of science in general.     

The impact of action learning on analysis of occupation

Technology and millennials have created a shift in the world and how it operates. This impact has been experienced in the field of occupational therapy education. As a result of this paradigm shift, an analysis of effective teaching methodologies was carried out to assess the most effective way to engage the millennials in an analysis of occupation process, which is a critical foundation for effective critical thinking and clinical practice for occupational therapists. An action learning assignment was utilized to bridge this gap. The action learning assignment immersed the students in a safe learning environment that recreated many types of domains that needed to be analyzed. As a result, the students experienced first-hand the outcomes of effective and ineffective analysis and problem-solving during their action learning project. Therefore, the students were able to reflect and critically think through alternatives and hear about other students' projects. Overall, the action learning project yielded positive learning and engaging outcomes.     

The effects of self-explanation training on students' problem solving in high-school mathematics

The performance of a group of grade 9 mathematics students trained to use a self-explanation procedure during study of a new theorem in geometry was compared with that of students who used their usual study procedures. The processing activities used by the students during the study session and those used in a subsequent problem-solving test were observed. The focus of analysis on both occasions was on the knowledge access, knowledge generation, management and elaboration activities used by students. The self-explanation group showed more frequent use of each type of activity and also obtained higher scores on the problem-solving test. The difference in post-test performance of the groups was greatest on a set of far-transfer items. These items required the students to extend their use of the newly learned theorem to problem types that were substantially different from those presented in the original study material. Of particular note was the carryover effect of self-explanation training to students' processing in the subsequent problem-solving session. The relationships among the processing activities, students' beliefs, prior knowledge and post-test performance were examined using a partial least-squares path analysis procedure. Use of the self-explanation method had an indirect effect on performance, this effect being mediated by associated knowledge access and knowledge generation activity. There was no direct effect of method on performance. The strongest predictor of performance was the level of knowledge generation activity during which students showed evidence of making novel connections, either within the newly presented study material or between parts of that material and their existing geometry knowledge. In the final path model derived from the analysis of student performance, the students' prior knowledge measure had both a weak direct on their problem-solving performance and an effect on that performance that was mediated by relationships with the knowledge access and knowledge generation variables in the model.
