  • We explore the structure and usefulness of the 3-D residual plot as a basic tool for dealing with interaction in generalized linear models. If predictors have an interaction effect, the shape obtained by rotating the 3-D residual plot will show its presence. To illustrate the use of this plot as an aid to exploring the interaction, we present an example of a binomial regression model using simulated data.

  • This study aimed at Evaluate Students' Interaction and Happiness in Distance Learning Among Students with Learning-Difficulties, by identifying the level of students' interaction in distance education and differences between them, as well as its impact on their happiness to learn. To achieve the aim of the study, two scales were designed for this purpose and were applied to a sample consisting of (310) individuals. The results showed that the level of students' interaction through the e-learning platform was at a high level. The results also showed that there was no statistically significant difference between the mean scores of males and females in the scale of students' interaction through the e-learning platform. There was no statistically significant difference between them in their happiness for distance learning via the online platform. There were also no statistically significant differences related to the grade variable in the level of interaction through the electronic platform and in the happiness to learn, while there was a positive statistically significant effect of interaction through the electronic platform on students' happiness to learn.

  • The current study investigates how student-teacher interaction can be developed through task-based teaching in undergraduate students' Saudi teaching and learning context. An experiment was conducted for five weeks on 85 male undergraduate students at a Saudi public university based in Jeddah, Saudi Arabia. The study investigated different types of student-teacher interaction through task-based teaching (speaking activities). The results revealed that the experimental group (43 students) evinced much more enthusiasm, willingness, engagement and readiness in their inclass participation than their peers in the control group (42 students). The student-teacher interaction also helped students to be more responsive to general and specific topics in speaking activities. The study recommends that decision-makers in education make student-teacher interaction part of the student's monthly assessment. It also recommends that more efforts be made to foster the awareness of students, teachers, and parents awareness of the academic and non-academic importance of interaction. One final recommendation of the research is that student-teacher interaction should be more emphasized and integrated into the school curriculum and adopted as a critical teaching strategy.

  • GST pull-down assays were used to characterize the SARS-CoV membrane (M) and nucleocapsid (N) interaction, and it was found that the amino acids 211-254 of N protein were essential for this interaction. When tetrad glutamines (Q) were replaced with glutamic acids (E) at positions of 240-243 of the N protein, the interaction was disrupted.

  • The purpose of this study was to investigate interaction patterns and characteristics of small group discussions during elementary school science classes. Four heterogeneous groups were formed according to preferences and non-preferences, consisting of male and female students. Verbal interactions during small group discussions were audio and videotaped, transcribed and analyzed. The interaction frequency of each group was compared in terms of their cognitive and affective aspects. The results in terms of the cognitive aspect showed that there were no significant differences in the frequency of interaction between preference and non-preference groups' verbal behaviors. However, the quality of interaction was superior and the number of high level types of interaction were more frequent in the preference group. From the affective perspective, both groups of students exhibited a positive attitude in the preference group and a negative attitude in the non-preference group. The differences of interaction between the male and female student's groups were that in the case of the female group, the frequency and the quality of interaction was higher. Moreover, in contrast to male students, female students revealed satisfaction and favorable attitudes in their non-preference group because they felt more a acceptable atmosphere and attitude in that group. These results suggest that the interactions of the preference group are more interactive and elaborate in nature than those of the non-preference group.

  • The hydrodynamic interaction forces and moments induced by the vicinity of bank on a passing vessel are known as wall effects. In this paper, the characteristics of interaction acting on a passing vessel in the proximity of a semi-circle bank wall are described and illustrated, and the effects of ship velocity, water depth and the lateral distance between vessel and semi-circle bank wall are discussed. For spacing between ship and semi-circle bank wall (SP) less than about 0.2 L and depth to ship's draft ratio (h/d) less than around 2.0, the ship-bank interaction effects increase steeply as h/d decreases. However, for spacing between ship and semi-circle bank wall (SP) more than about 0.3 L, the ship-bank interaction effects increase slowly as h/d decreases, regardless of the water depth. Also, for spacing between ship and semi-circle bank wall (SP) less than about 0.2 L, the hydrodynamic interaction effects acting on large vessel increase largely as ship velocity increases. In the meantime, for spacing between ship and semi-circle bank wall ($S_P$) more than 0.3 L, the interaction effects increase slowly as ship velocity increases.

  • According to social constructivism, group interaction is very important when students construct their knowledge. Many researchers have developed methods of teaching on the basis of group interaction because they recognized the importance of group interaction. There are a large variety of issues related to group interaction including group size, the gender and ability composition of groups, seating arrangements, textbook use, gestures, and role assignments. However, research on group interaction in science learning is still insufficient. In this study, we focused upon the emerging role of the primary leader. We investigated the primary leader's diverse role when students are solving mechanics problems. The participants were one group composed of three students in an upper-level mechanics class. To analyze these students' group interactions, their verbal interactions during meetings were videotaped and audiotaped during one-semester period. We also conducted interviews with the three students and analyzed their reports. As a result, we could find a special student who had the role of primary leader. We could also find the leader's three different leadership roles in different problem situations by inductively; explainer, facilitator and evaluator. Group interaction had different aspect according to the different role of leaders. The group interactions were the most active when the leader played the role of facilitator.

  • This paper presents a method for generating an autonomous activity-based diary in the environment including a personal computer (PC). In order to record a user's various tasks in front of a PC, we consider the contextual information such as current time, opened programs, and user interactions. As one modality for the user interaction, a motion sensor was applied to recognize a user's hand gestures in case that the activity is conducted without interaction between the user and the PC. Moreover, we propose a temporal clustering method to recapitulate the sequential and meaningful activity in the stream of extracted PC usage logs. By combining those two processes, we summarize the user activities in the PC environment.

  • 본 연구는 과학 실천 수업을 위한 교사학습공동체 중학교 과학교사들의 PCK 요소 간 상호작용 탐색을 목적으로 한다. 이를 위해 교사학습공동체에 참여하는 5명의 교사를 대상으로 사전·사후 설문과 면담, 교사학습공동체 논의 녹음, 수업계획안, 수업 영상, 수업 일기 등의 자료를 수집하여 질적 분석을 하였다. 교사학습공동체 교사들의 과학 실천 수업 PCK 요소 간 상호작용은 일방적으로 영향을 미치는 단방향 상호작용과 서로 영향을 주기도 하고 받기도 하는 양방향 상호작용의 두 가지 유형으로 나타났다. 상호작용이 일회성으로 그치거나 연쇄적으로 일어나기도 했으며, 양방향 상호작용의 경우에는 교사학습공동체 한 모임에서 동시적으로 상호작용이 이루어지거나, 교사학습공동체 여러 모임을 거쳐 연속적으로 양방향 상호작용이 이루어지기도 했다. 본 연구는 교사학습공동체의 협력적 학습 맥락이 다양한 PCK 요소 및 하위요소 간 여러 가지 상호작용을 복합적으로 촉진하는 환경을 조성할 수 있다는 시사점을 제공한다.
