The purpose of this study was to investigate the effect of motivation promotion on task performance. Unlike most previous studies that have used survey methods, this study examined the effects of motivation promotion on arithmetic and linguistic task performances under experimental conditions. Effort-inducing instructions and positive feedbacks were used to promote participants' motivation. Experiments 1 and 2 examined the effect of effort-inducing instructions and positive feedback on participants' autonomous selection of task difficulty when performing arithmetic and linguistic tasks. The results of the both experiments showed that the experimental group which received effort-inducing instructions and positive feedback chose more difficult task than the control group did. Experiment 3 examined whether motivation promotion enhances task performance and task persistence. The experimental group was more accurate and persistent than the control group. The results of the current study offer experimental evidence suggesting that activating intrinsic motivation through motivation promotion improves attitudes toward tasks and task performance.

Approximate number sense(hereafter, ANS) is the ability to compare and operate upon numerosity information. The numerosity comparison task is used to measure ANS. However, there is considerable variance among previous reports of ANS acuity which may be related to different task formats used. Here, we aim to investigate whether the format of the numerosity comparison task influences measurements of ANS acuity. We compared two task formats; 1) an intermixed format presenting two intermixed arrays of black and white dots, and 2) a side-by-side format showing two arrays of dots side by side. The intermixed format likely makes additional demands on general cognitive resources for inhibitory control, selective attention, or visuospatial working memory. The performance on the intermixed format was significantly lower than that of the side-by-side format resulting in an underestimation of ANS acuity compared to the expected trajectory of ANS development. In addition, the ANS acuity measured from only the side-by-side format was correlated with children's mathematical achievement and age. Our results demonstrate that measurement of ANS from the side-by-side format has higher construct and predictive validity compared to that of the intermixed format.

As policy support for the modular construction method and measures to expand the market are being prepared, it is time to present and analyze clear tasks for activation. Therefore, this study aims to present core tasks for activating the modular construction method. The tasks were reviewed through analysis of existing research and supplemented through expert interviews to derive 30 core tasks. Following this, a questionnaire survey was conducted to analyze the important and urgent of these core tasks and to determine their priorities. The results of this study can contribute to a strategic approach for solving the core tasks necessary for revitalizing modular construction.

This paper investigates the teaching and learning of Linear function relating functional contexts and suggests the improved methods of representation-shift through this analysis. The methods emphasize the link between students' preacquired knowledge of mathematical representations and the way of using those. This methods are explanatory teaching, teaching and teaming based on modelling perspectives or tasks (interpretation, prediction, translation and scaling). We categorize the 8th grade middle school students' errors on the linear function relating real contexts and make a comparative study of the error-remedial effects and the teaching and teaming methods. We present the results of a study in which representation-shift methods based on modelling perspectives and tasks are more effective in terms of flexible connection of representations and error remediation. Also, We describe how students used modelling perspective-taking to explain and justify their conceptual models, to assess the quality of their models and to make connection to other mathematical representation during the problem solving focusing on the students' self-diagnosis.

The purpose of the study is to analyze the levels of cognitive demands and components of the reasoning process presented in the mathematical sequence section of three high school mathematics textbooks in order to provide implications for the development of reasoning tasks in the future mathematics textbooks. The results of the study have revealed that most of the reasoning tasks presented in the mathematical sequence section of the three high school mathematics textbooks seemed to require low-level cognitive demands and that low-level cognitive demands reasoning tasks required only a component of one reasoning process. On the other hand, only a portion of the reasoning tasks appeared to require high-level of cognitive demands, and high-level cognitive demands reasoning tasks required various components of reasoning process. Considering the results of the study, it seems to suggest that we need more high-level cognitive demands reasoning tasks to develop high-level cognitive reasoning that would provide students with learning opportunities for various processes of reasoning, and that would provide a deeper understanding of the nature of reasoning.

This study aims to propose task areas which have to be discussed for reforming of the Public Records and Archives Act in Korea. For drawing the task areas, it analysed the pending issues mainly presented in the policy forums co-hosted by Korean Society of Archival Studies and Korean Association of Records Managers and Archivists, and examined researches providing tasks of revising of the law or rebuilding public records policies related in digital records management. The 4 task areas were identified, which were the exhaustive documentation of the public agencies' activities, the reexamination of the appraisal systems for public records and archives, the transition into the 2nd generation-digital records management, and the redefinition of roles and responsibilities of the records/archival institutions. Then it placed the issues into the 4 areas, and proposed some suggestions for further discussions in each tasks. Reminding that the task areas proposed in this study are not comprehensive, further suggestions and arguments will be expected for reforming the Public Records and Archives Act.

Prior research on attribution has paid much attention to cognitive processes through which people infer causes. However, surprising omission from this research stream is the role of unconscious priming of different causes in task satisfaction and re-performance intention. This research is conducted to examine how attributing to different causes (chance vs. effort) via priming procedure affects task satisfaction and re-performance intention. To do this, participants were assigned to either chance-priming or effort-priming attribution condition and asked to answer O/X quiz (Exp 1) or multiple choice questions (Exp 2). Then, we provided 'Good' or 'Bad' feedback to participants randomly regardless of their actual task results. Finally, we measured their task satisfaction and re-performance intention. Results indicate that task satisfaction is affected by the valence of feedback they received but re-performance intention is influenced by interaction between attribution priming and the valence of feedback. Specifically, when receiving 'Good' feedback, participants in effort-priming condition have higher re-performance intention than those in chance-priming condition, whereas when receiving 'Bad' feedback, participants in effort-priming condition have lower re-performance intention than those in chance-priming condition. Implications of the findings are discussed in relation to the research for induction and decision making as well as psychology of addiction.

The purpose of this study is to investigate the effects of research project activities using the science writing heuristic on science inquiry abilities and attitudes toward science in high school students. For this purpose, we conducted the research project activities using the science writing heuristic consisting of questioning, experimental design, observation, argument and evidence, reading, and reflection steps for 73 students of the second year of science core course in high school in Jeonnam. In order to analyze the effects of the program, we surveyed the scientific inquiry ability and attitude toward science, investigated the perception of the research project class applying science writing heuristic, and conducted interviews when there was difficulty in interpreting the results. And the results of this study are as follows. First, among the science inquiry abilities, the score of Reasoning, Hypothesis setting, Finding variables, Operational definition, Experimental design, Graphing and data interpretation, Generalization was significantly improved statistically (p<.05), but the score of Expectation was not statistically significant (p>.05). Second, among the attitudes toward science, the score of 'Leisure interest in science', 'Enjoyment of science lessons', 'Career interest in science' was significantly improved statistically (p<.05). And the score of 'Attitude to scientific inquiry' decreased but it's not significant statistically. The high school research project applying science writing heuristic had a positive effect on scientific inquiry ability and scientific attitude but it could be burden to students because it is led by students in a form different from general science class for a long time. And so continuous study on research project that minimize these disadvantages and maximize their merits is needed.
