This study aimed to explore preschool teachers’ actions in order to support children’s learning processes in a context where an interactive whiteboard (IWB) is used. Five preschool teachers and 22 children aged 4–6 were video observed in 2017 and early spring 2018 over a period of 5 months. The findings of the study revealed 21 scaffolding actions which preschool teachers used including: Concretizing, Questioning, Instructing, Providing space, Affirming, Providing feedback, Inviting, Watching, Laughing together, Approaching, Standing/sitting beside, Simplifying, Filling in the blanks, Confirming, Participating, Challenging perception, Challenging thought, Explaining facts, Displaying, Explaining solutions, and Referring back. By characterizing teachers’ actions in relation to different scaffolding functions, the relationship between action and scaffolding function was particularly clarified. Six of the functions, including recruitment, direction maintenance, marking critical features, reduction in degrees of freedom, frustration control and demonstration were aligned with Wood et al.’s (Child Psychol Psychiatry 17:88–100, 1976) theoretical framework. By identifying two additional functions, i.e., mutual enjoyment and participation in the activity, more importantly the study contributed to the development of Wood et al.’s (Child Psychol Psychiatry 17:88–100, 1976) theoretical framework. It can be said that the findings of the study expanded and deepened our understanding regarding scaffolding processes and the ways they can be implemented in teaching practices.

A proof is a connected sequence of assertions that includes a set of accepted statements, forms of reasoning and modes of representing arguments. Assuming reasoning to be central to proving and aiming to develop knowledge about how teacher actions may promote students' mathematical reasoning, we conduct design research where whole-class mathematical discussions triggered by exploratory tasks play a key role. We take mathematical reasoning as making justified inferences and we consider generalizing and justifying central reasoning processes. Regarding teacher actions, we consider inviting, informing/suggesting, supporting/guiding and challenging actions can be identified in whole-class discussions. This paper presents design principles for an intervention geared to tackle such reasoning processes and focuses on a whole-class discussion on a grade 7 lesson about linear equations and functions. Data analysis concerns teacher actions in relation to design principles and to the sought mathematical reasoning processes. The conclusions highlight teacher actions that lead students to generalize and justify. Generalizations may arise from a central challenging action or from several guiding actions. Regarding justifications, a main challenging action seems to be essential, while follow-up guiding actions may promote a further development of this reasoning process. Thus, this paper provides a set of design principles and a characterization of teacher actions which enhance students' mathematical reasoning processes such as generalization and justification.

The video camera is essential for reliable activity monitoring, and a robust analysis helps in efficient interpretation. The systematic assessment of classroom activity through videos can help understand engagement levels from the perspective of both students and teachers. This practice can also help in robot-assistive classroom monitoring in the context of human–robot interaction. Therefore, we propose a novel algorithm for student–teacher activity recognition using 3D CNN (STAR-3D). The experiment is carried out using India’s indigenously developed supercomputer PARAM Shivay by the Centre for Development of Advanced Computing (C-DAC), Pune, India, under the National Supercomputing Mission (NSM), with a peak performance of 837 TeraFlops. The EduNet dataset (registered under the trademark of the DRSTATM dataset), a self-developed video dataset for classroom activities with 20 action classes, is used to train the model. Due to the unavailability of similar datasets containing both students’ and teachers’ actions, training, testing, and validation are only carried out on the EduNet dataset with 83.5% accuracy. To the best of our knowledge, this is the first attempt to develop an end-to-end algorithm that recognises both the students’ and teachers’ activities in the classroom environment, and it mainly focuses on school levels (K-12). In addition, a comparison with other approaches in the same domain shows our work’s novelty. This novel algorithm will also influence the researcher in exploring research on the “Convergence of High-Performance Computing and Artificial Intelligence”. We also present future research directions to integrate the STAR-3D algorithm with robots for classroom monitoring.

This study aims to increase understanding of the values and outcomes of teacher action research in conservatoire education. Teacher action research has been found to stimulate both professional development and improvement of teaching practice. A multiple-case study design was employed to examine teachers’ activities and their perceptions of the value of action research. Findings from the cross-case analysis include teachers’ perceptions of action research as a way to stimulate the advancement of both their teaching practice and their professional development. Constructive collaborations and self-reflections related to teacher action research were found to reinforce their learning and teaching.

The study focuses on using collaborative action research projects to promote reflective practice of pre-service teachers during the internship. Research groups were composed by school tutors and pre-service teachers, assisted by the teacher educator. Twelve pre-service teachers and six school tutors were organized in three groups, two tutors and four pre-service teachers per group. Each group worked with a topic coming from problems found in the internship experience. Pre-service teachers conducted classroom observation of their tutors and classmates as well as classroom teaching by themselves. They also wrote reflective diaries of these observations and their own teaching, and participated in a learning community which was a nurturing collaborative atmosphere that provided time, space and collegial peers to share experiences and solve problems. By examining the research experience, there are some important results: a) Collaborative action research helped pre-service teachers to study and develop reflective practice abilities while participating in a learning community which somewhat filled the gaps left by the lack of some tutors’ good role modeling; b) The role of the teacher educator for improving relationships between school tutors and pre-service teachers seemed crucial in both the preventive role and remedial role; c) There is still room for improvement, especially concerning tutors’ modeling and scaffolding high quality reflective teaching practices; d) Therefore, the training of competent internship tutors is significant, and relevant incentive policies should be formulated to motivate middle school teachers to act as internship tutors.

In argumentation-based science teaching, teachers play an important role and are the main party responsible for the introduction of argumentation in classrooms. In this study, we discuss how actions that contribute to science teaching involving argumentation are expressed by a teacher on leading different types of didactic sequences, and how such actions relate to teachers’ knowledge with regard to argumentation and teachers’ pedagogical content knowledge (PCK). For this reason, we have constructed an instrumental case study, based on the observation of four didactic sequences led by an experienced teacher, and through interviews with her. From their analysis, we conclude that the goals set by the teacher in the didactic sequences have had an influence upon the actions that contribute to science teaching involving argumentation shown by the teacher, suggesting a strong link between the elements of PCK and those of the Knowledge for Teachers’ Actions through Argumentation. As possible consequences, we draw attention to the need to add value to a hybrid method for teaching argumentation, involving implicit and explicit teaching, as well as the proposal of the set of actions that contribute to science teaching involving argumentation. This can contribute towards the investigations into the role of teachers within argumentation-based science teaching, and to teacher education.

In mathematics, there are four basic operations that students must master from the elementary school level, namely addition, subtraction, multiplication, and division. However, some students experience difficulties or misunderstandings in interpreting multiplication as repeated addition. This research aims to improve the learning outcomes of second-grade students on multiplication material in elementary schools. This research used the teacher action research approach with 20 second-grade students at Kepuhan Sewon Public Elementary School as participants. Apart from that, this research used two data collection methods, namely providing mathematical worksheets and observations carried out by special observers. Data analysis was carried out by looking at the students’ average scores, reflecting through focus group discussions with observers, and filling in observation sheets by the teacher. Furthermore, the results of this research are presented in the form of teacher observation sheet scores and mathematical worksheets work results. The score results on the observation sheet show an increase in scores from learning in cycle 1 to cycle 2. In addition, the average score of students’ mathematical worksheets after intervention in the form of smart suitcase media and mathematical worksheets always increases with pre-cycle details (82), cycle I (93), and cycle II (94). Thus, the use of smart suitcase media assisted by mathematical worksheets has direct implications for improving the learning outcomes of second-grade students in the material of multiplication of integers.

The aim of this article was to determine the factors in teachers’ actions that could explain differences in the emotional atmosphere of primary school classrooms. Based on pupils’ drawings about their mathematics lessons, we analyzed both the pupils’ and their teachers’ actions, including pupils requesting help, sitting alone, and talking about mathematics, as well as the teacher helping, praising and criticizing. We could conclude that the teacher has a central role in the formation of the emotional atmosphere in mathematics lessons. The emotional atmosphere can be built up to be positive when the teacher encourages the pupils to talk about mathematics and their own understanding with each other. The emotional atmosphere is then open and tolerant. The emotional atmosphere can turn to be negative when the pupils are working by themselves and are afraid of criticism and embarrassment.

Many studies in mathematics education have emphasized the importance of attending to students’ interactions, particularly, their mathematical reasoning when collaborating on solving problems. However, the question of how teachers can facilitate students’ productive interactions for learning mathematics, is still a challenging one. This case study aims to provide detailed insights into opportunities and limitations related to teachers’ actions for the productivity of students’ interactional patterns solving a linear function problem together. Four student-pairs in the first year of upper secondary school (11th grade) serve as a background on students’ interactional patterns, which in this study focused on three interactional aspects: collaborative processes, mathematical reasoning, and exercised agency. The student-pairs’ three teachers provide insights on teacher actions observed as different funneling and focusing actions, which elucidated opportunities and limitations in several situations influencing the productivity of students’ interactional patterns. The study used purposive sampling in selecting the particular school and three teachers, which were chosen based on acquaintances and willingness to participate in the study. The students’ interaction when solving the mathematical problem and the teachers’ interaction with the pairs were video recorded and observed by the researchers. The analysis method was a deductive analytical strategy, where specific events of interactions were identified, based on the three interactional aspects combined with teacher actions. Coding schemes on students’ interactions were used, as well as on teacher actions. The findings indicate that teachers’ actions and questions influenced students’ interactions, but mainly their reasoning, and particularly the primary agent’s reasoning. Moreover, students who were engaged in interactional patterns called bi-directional and one-directional did not change their ways of interacting after a teacher interaction. Thus, the teachers’ actions did not impact students’ collaborative processes and agencies in the same way as their reasoning. This study adds to the field of mathematics education by illuminating the importance of teachers being aware of students’ roles when they work together, for facilitating a productive interaction for both students in dyads. The study highlights the importance of further research on teacher actions and teacher awareness for facilitating collaborative situations of bi-directional interactions for students’ shared understanding of mathematical concepts and ideas.

This article focuses on the use of conversation analysis (CA) to help teaching interactional competence in English to adult second language learners from lower to intermediate levels. To set the context, this article gives a brief overview on the use of CA in second language research as well as considering the construct of interactional competence in second language teaching. Based on classroom research, the article demonstrates how CA applied in the second language classroom was effective initially in raising students' awareness of both the mechanisms and norms of spoken interaction, and also eventually in helping them to become analysts of conversation and more effective conversationalists. To better understand what CA concepts needed to be taught a conversation analysis of the students' undirected conversations was undertaken revealing interactional problems not noticed through traditional methods of investigation. It is therefore suggested that a CA-informed pedagogical approach can help to teach interactional competence or competencies, by using materials designed for that purpose. (Verlag).
