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.     

The effects of a combination of text structure awareness and graphic postorganizers on recall and retention of science knowledge

The purpose of this study was to determine the effectiveness of a self-regulated strategy on immediate recall and retention of science knowledge in community-college anatomy and physiology students who participated in a 14-hour (8 weeks) study skills class. The class emphasized the recognition of five common science textbook text structures (cause and effect, classification, enumeration, generalization, and sequence) and the construction of graphic postorganizers of the text structures. A pretest, two immediate posttests, and a retention posttest were used to measure recall and retention. Results indicated that on immediate posttests students who actively constructed graphic postorganizers of the test structure recalled significantly more content than did the control students who simply underlined, reread, or highlighted. On a 3-week retention posttest, those students in the study skills class retained significantly more of the material studied than did the control group of students.     

The effect of knowledge of correct results per item on verbal learning and retention

A report of an experiment to measure the effects of both overt and covert responses to educational stimuli with KCR (knowledge of correct results) feedback provided. In most studies of feedback, KCR (or KR) is given as a consequence of an overt response: Stimulus-Response-Feedback. In the case of a covert response, the student constructs his answer but does not react overtly to the presentation of a stimulus item. Forty Ss were randomly assigned to 1 of 4 groups further divided into 1 control group receiving no feedback and 3 groups receiving information (KCR) according to either overt or covert response patterns. A 25-item multiple-choice test was administered 5 times by means of a terminal consisting of a screen and a teletype. Results showed that the covert paradigm was the most effective. The experiment did not demonstrate that the covert process leads to better performance on a test administered later to measure retention. A tentative explanation for this negative result was that the time interval between the provision of feedback and presentation of the next item was of some relevance. A multiple comparison test revealed that the 3 treatment groups performed better than the control group.     

Redesigning problem-based learning in the knowledge creation paradigm for school science learning

The introduction of problem-based learning into K-12 science classrooms faces the challenge of achieving the dual goal of learning science content and developing problem-solving skills. To overcome this content-process tension in science classrooms, we employed the knowledge-creation approach as a boundary object between the two seemingly contradicting activities: learning of science content and developing problem-solving skills. As part of a design research, we studied a group of Grade 9 students who were solving a problem related to the Law of Conservation of Energy. Through the lens of the activity theory, we found that students’ understanding of the intended science knowledge deepened as they made sense of the disciplinary-content knowledge in the context of the problem and concurrently, the students successfully developed solutions for the problem. This study shows that developing problem-solving competencies and content learning need not be disparate activities. On the contrary, we can harness the interdependency of these two activities to achieve dual goals in learning.     

The effects of computer-supported self-regulation in science inquiry on learning outcomes,learning processes,and self-efficacy

Recently, researchers have demonstrated the benefits of technology-enhanced science inquiry activities. To improve students’ self-regulation and assist them in controlling their own learning pace through inquiry activities, in this study, a self-regulated science inquiry approach was developed to assist them in organizing information from their real-world exploration. A quasi-experimental design was conducted in an elementary school natural science course to evaluate the students’ performance using the proposed learning approach. One class assigned as the treatment group learned with the self-regulated science inquiry approach, while the other class assigned as the control group learned with the conventional science inquiry approach. The students’ learning achievement, tendency of information help seeking, tendency of self-regulation, and self-efficacy were evaluated. The results of the study revealed that the self-regulated science inquiry approach improved the students’ learning achievement, especially for those students with higher self-regulation. In addition, the students who conducted inquiry with the self-regulated learning strategy increased their tendency of information help seeking, self-efficacy, and several aspects of self-regulation, including time management, help seeking, and self-evaluation. Accordingly, this study demonstrated the effectiveness of the self-regulated learning strategy, an approach with high learner control, in terms of improving students’ learning achievement and their self-regulation.     

The effects of cross-modality and level of self-regulated learning on knowledge acquisition with smartpads

Recently, there has been a transition from traditional paper or computer-based learning environments to smartpad-based learning environments, which are based on touch and involve various cognitive strategies such as touch operation and note taking. Accordingly, the use of smartpads can provide an effective learning environment through cross-modality, which simultaneously integrates information using two or more sensory modalities. Based on this rationale, this study investigated the effects of cross-modality (vision and tactility) on knowledge acquisition in a smartpad-based learning environment. Interaction between different modalities and learners’ self-regulated learning (SRL) skills was also tested. Ninety-nine college students were randomly assigned to three different learning environments: paper-based, smartpad-based unimodal, and smartpad-based cross-modal environments. Students were differentiated according to high and low SRL skill levels. The findings suggest that the participants in the smartpad-based cross-modal environment significantly outperformed the participants in the smartpad-based unimodal environment pertinent to identification and comprehension knowledge acquisition. Furthermore, the participants in the smartpad-based cross-modal environment performed equally with the participants in the paper-based environment.     

Interactive pedagogy and subsequent effects on learning in science classrooms

Observations of pupils‐in‐action whilst carrying out investigations indicated that there was plenty of social and cooperative exchange. There was, however, infrequent discussion regarding the planning of experimental approaches, predicting outcomes, consideration of the meaning of evidence and evaluation of task solutions. These observations informed the nature of interactive in‐service programmes developed in Keele University Education Department. Professional development was designed to purposely illustrate a wide repertoire of pedagogic strategies that focused around these issues to support cognitive development of pupils. The interactive nature of the in‐service training was shown to affect widespread ‘change in teachers’ practice. These teachers, involved in experiential in‐service, reflected that they intervened more regularly in children's learning. Their engagement in in‐service training as learners in problem‐solving situations resulted in conceptual shifts in understanding the learning processes their pedagogical transformations could affect. The impact of this changed praxis on pupils' learning in investigational situations was studied after in‐service intervention. These findings were compared with the performance of pupils of the same year group carrying out the same investigations before in‐service intervention. The more interactive nature of the teachers' changed pedagogy appeared to affect change in the way pupils themselves interacted and learnt from and with each other. Explicitly sharing subjective views through exploratory talk was found to be important to affect learning through social interaction.     

Effect of instruction using students' prior knowledge and conceptual change strategies on science learning

One of the factors affecting students' learning in science is their existing knowledge prior to instruction. The students' prior knowledge provides an indication of the alternative conceptions as well as the scientific conceptions possessed by the students. This study is concerned primarily with students' alternative conceptions and with instructional strategies to effect the learning of scientific conceptions; i.e., to effect conceptual change from alternative to scientific conceptions. The conceptual change model used here suggests conditions under which alternative conceptions can be replaced by or differentiated into scientific conceptions and new conceptions can be integrated with existing conceptions. The instructional strategy and materials were developed for a particular student population, namely, black high school students in South Africa, using their previously identified prior knowledge (conceptions and alternative conceptions) and incorporate the principles for conceptual change. The conceptions involved were mass, volume, and density. An experimental group of students was taught these concepts using the special instructional strategy and materials. A control group was taught the same concepts using a traditional strategy and materials. Pre- and posttests were used to assess the conceptual change that occurred in the experimental and control groups. The results showed a significantly larger improvement in the acquisition of scientific conceptions as a result of the instructional strategy and materials which explicitly dealt with student alternative conceptions.     

Management of science classroom tasks and effects on students' learning opportunities

This study examined the work that students completed during six or seven week units of instruction in four different science classes. The purpose of the study was to assess the kinds of learning opportunities students had as they dealt with science content and the problems teachers faced in managing different kinds of assignments, particularly assignments that required students to use higher level cognitive operations. Management strategies associated with these assignments are described and the effects of these strategies are considered.     

Does the presentation style of questions inserted into text influence understanding and retention of science concepts?

The purpose of this research was to determine the relative effects of the presentation style of questions inserted into text materials for students in university introductory biology. The sample was randomly assigned to seven treatment groups of approximately equal size and read a 2,354-word passage on bacterial adaptations taken from a popular university general biology textbook. Experimental treatment groups read the same passage with (1) questions placed at the beginning of selected paragraphs and with the questions presented with (2) underlining, (3) in uppercase, (4) set above the paragraph, (5) underlined and set above, and (6) set above in uppercase respectively. The criterion variable was a 20-item multiple-choice exam with five possible answers per question given once to all students immediately after they read the passage and again exactly four weeks later. Presentation strategy groups were contrasted against the reading without questions groups. Four of the six groups reading with questions at the beginning of the paragraph scored significantly higher on the test given immediately after the reading than the group reading without questions. There were no significant differences between any of the group scores for the test given four weeks after reading. Other differences in results between these strategies and implications for text writers are discussed.

The use of self‐learning modules to facilitate learning of basic science concepts in an integrated medical curriculum

This study used qualitative and quantitative approaches to evaluate the effectiveness of self‐learning modules (SLMs) developed to facilitate and individualize students' learning of basic medical sciences. Twenty physiology and nineteen microanatomy SLMs were designed with interactive images, animations, narrations, and self‐assessments. Of 41 medical students, 40 students voluntarily completed a questionnaire with open‐ended and closed‐ended items to evaluate students' attitudes and perspectives on the learning value of SLMs. Closed‐ended items were assessed on a five‐point Likert scale (5 = high score) and the data were expressed as mean ± standard deviation. Open‐ended questions further evaluated students' perspectives on the effectiveness of SLMs; student responses to open‐ended questions were analyzed to identify shared patterns or themes in their experience using SLMs. The results of the midterm examination were also analyzed to compare student performance on items related to SLMs and traditional sessions. Students positively evaluated their experience using the SLMs with an overall mean score of 4.25 (SD ± 0.84). Most students (97%) indicated that the SLMs improved understanding and facilitated learning basic science concepts. SLMs were reported to allow learner control, to help in preparation for subsequent in‐class discussion, and to improve understanding and retention. A significant difference in students' performance was observed when comparing SLM‐related items with non‐SLM items in the midterm examination (P < 0.05). In conclusion, the use of SLMs in an integrated basic science curriculum has the potential to individualize the teaching and improve the learning of basic sciences.

The concepts of science in Japanese and Western education

Using structural linguistics, the present article offers an impartial frame of reference to analyze science education in the non-Western world. In Japan, science education has been free from epistemological reflection because Japan regards science only as effective technology for modernization. By not taking account of the world-view aspect of science, Japan can treat science as not self-referential. Issues of science education are then rather simple; they are only concerned with the question of how to, and answers to this question are judged according to the efficiency achieved for modernization.Science, however, is a way of seeing nature. This word is generally translated into Japanese as shizen which has a totally different connotation and therefore does not lead to an understanding of the Western scientific spirit. Saussure's approach to language is used to expose the consequences of the misinterpretations that spring from this situation. In order to minimize or prevent these misinterpretations, it is emphasized that science education should be identified with foreign language education in the non-Western world.
