  • The experimental evidence evaluation of the 11th grade students(N:91) was investigated. Specially, the influence of students' ideas about optical phenomena and presented evidence types on their evidence evaluation, and the influence of students' ideas on their causal inference modes were investigated. After eliciting the students' ideas about shadow phenomena and conformity of their idea, the experimental results with a binary outcome were presented as the evidence. Then the students were asked to evaluate the evidence. Again students' ideas were elicited. Most of students had causal ideas such that the shape of object(96%) and the inclination of screen(75%) were causes of shadow shape, not the shape(70%) and color(92%) of light source. In the case of the shape of object and the color of light source, most students(70%) believed strongly their ideas. Most responses(80%) in the evidence were evidence-based, and 12% of them were theory-based. There was no significant difference of reponses types between students with causal ideas(81%) and students with non-causal ideas(78%), between covariable and non-covariable evidence. But in the case of non-causal ideas, covariable evidence was more likely to yield evidence-based reponses than non-covariable evidence. If students had preconcepts inconsistent(84%) with the evidence, they were more likely to make evidence-based responses than the students with consistent ideas (75%) with the evidence. Especially in the case perceptually biased evidence, this tendency was marked. In the case of covariable evidence, many students made inclusion inferences(40%) rather than uncertainty inferences(32%). In the case of uncertainty inferences(94%), students more likely to make evidence-based reponses than inclusion inferences(83%) and exclusion infernces(88%). In the case of inclusion inferences and exclusion infernces, students tended to make idea-based responses and distort the evidences. In conclusion, when the students evaluate the experimental evidences, their ideas influence the causal inference modes. Especially, according to the conformity of the preconcepts and logical relation of evidences, the inference modes are more strongly depended upon the preconcepts rather than evidences.

  • This study focuses on student engagement in Chinese middle school mathematics classrooms. By the recording and quantitative analysis on video case, this study explored the main acts and time of student engagement. The data showed that among the student engagements: (1) Students' responses to teacher's question occurred most frequently; (2) Collective responses were much more than the individual responses; (3) Students' responses and classroom practice spent the longest time; (4) The most frequent student engagements occurred in the aspects of classroom practice; and (5) Students rarely asked a question to teachers. The study also suggested that teacher's effective guidance could improve the level of student engagement and the content of classroom practice is very important to the quality of student engagement.

  • In this study, we investigated students' responses to a discrepant event and an alternative hypothesis which had been presented in the conceptual change processes from the phlogiston theory to the oxygen theory, and compared them with scientists' responses. The data concerning scientists' responses to the discrepant event and the alternative hypothesis were gathered from the relevant literature on the history of science. Subjects were 148 eighth graders who possessed the target misconception about combustion through a preconception test. After having been presented with the discrepant event and the alternative hypothesis, students were asked to respond to the test of response to discrepant event. Although similar types of responses were obtained from both scientists and students, there was also a clear difference. Scientists tended to focus on explaining the problems of the discrepant event, whereas students tended to ignore and/or exclude the discrepant event in order to maintain their previous beliefs. Only a few students were also found to change their beliefs after having been presented with the alternative hypothesis.

  • In this study, elementary school students' responses toward a discrepant event about a float-or-sink problem were investigated through semi-structured interviews. Initial participants were 61 fifth-grade students from two elementary schools. After excluding the students who did not possess the target misconception from the results of a preconception test and who were not willing to participate in an interview, 31 students (14 males and 17 females) were finally interviewed by two teacher-interviewers. During the interviews, students were first provided with a hands-on experiment which was the same as the situation in the preconception test, and then they were asked about believability of the discrepant event, inconsistency between the discrepant event and their existing conceptions, and belief change after experiencing the discrepant event. Interviews were audio- and video-taped, and then were transcribed by two interviewers. After analyzing the interview transcriptions, we found four types of students' responses; rejection, uncertainty, peripheral belief change, and belief change. We also found that belief change response type should be classified into three distinctive subtypes; belief decrease, ad-hoc belief change, and analytical-abductive belief change.

  • Thirty six EFL freshman students at the College of Languages and Translation, King Saud University, Riyadh, Saudi Arabia were given a dictation, a listening comprehension test and a decoding test. The purpose of the study was to find out whether EFL freshmen students' spelling ability correlates with their listening comprehension and decoding skills. Data analysis showed that the typical EFL freshman student misspelled 41.5% of the words on the dictation, gave 49.5% correct responses on the listening comprehension test, and 52% correct responses on the decoding test. The median and mean scores showed that the subjects' spelling, listening and decoding achievement is low, which implied that the subjects were having spelling, listening comprehension and decoding difficulties. The students' spelling errors and correct listening comprehension and decoding responses revealed strong correlations between spelling ability, listening comprehension and decoding skills. This means that good spelling ability in EFL is related to good listening comprehension and good decoding skills. The better the listening comprehension and decoding abilities, the fewer the spelling errors. When listening comprehension and decoding skills are poor, spelling ability is also poor. Recommendations for spelling, listening and decoding instruction are given.

  • This study describes a sixth-grade teacher's professional development journey through action research for improving students' responses in a mathematics class. In the action research, the influence a teacher's questioning tactics would have on students' ability to determine answer reasonability to mathematics problems was investigated. Drawing on qualitative analysis of the teacher's lessons, reflection journal and interviews as well as the classroom students' questionnaires and interviews, this study examines how action research can affect the teacher and the classroom students. The results suggest the popularization of action research among teachers by teacher training and development programs showing the positive changes in the teacher's performance leading to improved student responses.

  • This study primary aim is to investigate students' responses to experimental results which conflict with their preconceptions regarding electrical circuits. Eighty-eight students of both sexes were randomly selected from a science high school in Korea. They were questioned about their preconceptions regarding an electric circuit, and sixty-eight students with relevant misconceptions were selected. These students were presented with experimental results obtained by some other experimenter, and asked to interpret these results. The second aim of this study is to explore how students' responses vary according to the type of inquiry-skills required to obtain the result. To do this, two type of experimental results were developed: one obtained by observation and the other obtained by controlling variables. We found that many students doubted results for the simple reason that they conflicted with their preconceptions. They rejected results by mentioning other factors which could have affected the result, or simply by reiterating their preconceptions. This behaviour varied considerably by inquiry-skill type. 41% of students rejected conflictual result obtained by observation, but only 6% of students rejected results obtained by controlling variables.

  • The purposes of this study were to investigate students' perception on importance and performance of service quality of university foodservice, and to examine Importance-Performance Analysis(IPA) of foodservice quality for male and female students. A total of 500 university students in Daejeon were surveyed and 432 responses were returned. Excluding responses with significant missing data, 412 responses were used for data analysis. In terms of importance of service quality attributes, 'sanitation(4.74)' category received the highest score, followed by 'food(4.36)', 'service(4.22)', 'convenience(4.01)', 'menu(3.90)' and 'atmosphere(3.73)'. In terms of performance, the highest service quality attribute was associated with 'convenience(3.30)', followed by 'service(3.06)', 'sanitation(2.95)', 'food(2.88)', 'atmosphere(2.79)' and 'menu(2.68)'. As the results of IPA, 'staff's kindness', 'overall quality of service', 'taste of the food', 'freshness of the food', 'overall quality of the food', and 'cleanliness of the facility' fell into the Quadrant IV(Focus here) for female students. On the other hand, male students' IPA grid illustrated that 'taste of the food', 'freshness of the food', 'nutrition of the food', 'sanitation of the food', and 'sanitation of the utensils' fell into Quadrant IV(Focus here).

  • The purpose and content of Chonnam National University Center for Science Talented Education program and students' responses were described. The program was developed with the purpose of providing various learning opportunities for science talented students according to the level of their learning abilities. Students are given a variety of activities based on their potentials and interest. The program was developed in four subjects, such as mathematics, information science, science Ⅰ (physics and earth science), and science Ⅱ (biology and chemistry). Each subject consisted of simple inquiry, advanced one, and project, even though it had its own distinctions. Students were selected for each subject based on two criteria, that is, achievements in school science or mathematics (the upper 3 percent of the 8th grade students) and examination scores. Means and standard deviations for each subject were as follows: 51.8 and 13.3 for Science Ⅰ, 53.1 and 13.9 for Science Ⅱ, 36.7 and 10.7 for mathematics and 36.4 and 12.5 for information science. Thirty hours of summer classes were performed, and a survey was administered to obtain students' responses concerning difficulty, interest, teaching and content of the program. They gave relatively favourable responses in most area, but lack of time for studying was revealed in mathematics and information science. Further study in needed to get detailed and more accurate results of our program.
