Examining the Tasks of Teaching When Using Students' Mathematical Thinking

Recent research suggests that the examination of students' work may lead to changes in teaching practice that are more effective in terms of students' mathematical learning. However, the link between the examination of students' work and the teachers' actions in the classroom is largely unexamined, particularly at the secondary level. In this paper, I present the results of a study in which teachers had extensive opportunities to examine the development of students' conceptual models of exponential growth in the context of their own classrooms. I describe two related aspects of the practice of one teacher: (a) how she listened to students' alternative solution strategies and (b) how she responded to these strategies in her practice. The results of the analysis suggest that as the teacher listened to her students, she developed a sophisticated schema for understanding the diversity of student thinking. The actions of the teacher supported extensive student engagement with the task and led the students to revise and refine their own mathematical thinking. This latter action reflects a significant shift in classroom practice from the role of the teacher as evaluator of student ideas to the role of students as self-evaluators of their emerging ideas.     

Interpersonal behaviour in senior high school biology classes

This article describes the first use of the Questionnaire on Teacher Interaction in senior biology classes and describes students' perceptions of their interpersonal relationships with their teachers in the classroom environment. The article also describes associations between students' perceptions of interpersonal relationships with their teachers and student outcomes. The study confirmed the reliability and validity of the QTI when used in senior secondary biology classes. Generally, the dimensions of the QTI were found to be significantly associated with student attitude scores. In particular, students' attitude scores were higher in classrooms in which students perceived greater leadership, helpful/friendly, and understanding behaviours in their teachers.

Different approaches to classroom environments based on teacher experience and effectiveness

The purpose of this qualitative instrumental case study was to continue looking at the differences in classroom environments for different levels of teachers. Specifically, we wanted to focus on teacher perspectives of classroom management, relationships with students, motivating students, student risk-taking within the classroom, and student self-regulation. The three levels we looked at for this study included highly effective teachers, proficient teachers who have taught for more than 3 years, and new/developing teachers. The results found three major themes with differences in how teachers at each level approached classroom management, relationships with students, and student behaviors within the classroom. The student behaviors within the classroom included self-regulation and risk-taking. The results of this study provide researchers more information regarding the different stages of teaching, information to schools on ways to mentor teachers at each level of teaching, and information to teacher preparation programs on ways to help preservice teachers prepare for the classroom.     

Disconnections Between Teacher Expectations and Student Confidence in Bioethics

This study examines how student practice of scientific argumentation using socioscientific bioethics issues affects both teacher expectations of students’ general performance and student confidence in their own work. When teachers use bioethical issues in the classroom students can gain not only biology content knowledge but also important decision-making skills. Learning bioethics through scientific argumentation gives students opportunities to express their ideas, formulate educated opinions and value others’ viewpoints. Research has shown that science teachers’ expectations of student success and knowledge directly influence student achievement and confidence levels. Our study analyzes pre-course and post-course surveys completed by students enrolled in a university level bioethics course (n = 111) and by faculty in the College of Biology and Agriculture faculty (n = 34) based on their perceptions of student confidence. Additionally, student data were collected from classroom observations and interviews. Data analysis showed a disconnect between faculty and students perceptions of confidence for both knowledge and the use of science argumentation. Student reports of their confidence levels regarding various bioethical issues were higher than faculty reports. A further disconnect showed up between students’ preferred learning styles and the general faculty’s common teaching methods; students learned more by practicing scientific argumentation than listening to traditional lectures. Students who completed a bioethics course that included practice in scientific argumentation, significantly increased their confidence levels. This study suggests that professors’ expectations and teaching styles influence student confidence levels in both knowledge and scientific argumentation.     

Flipping Quantitative Classes: A Triple Win

In the “flipped” class, students use online materials to learn what is traditionally learned by attending lectures, and class time is used for interactive group learning. A required quantitative business class was taught as a flipped classroom in an attempt to improve student satisfaction in the course and reduce the “transactional distance” (perceived barriers to engaging with the instructor, other students, technology, and course content) and increase satisfaction. Analysis indicated improvements to both transactional distance and student satisfaction in the flipped classroom. Multiple regression analysis quantified the extent of which each transactional distance was a predictor of student satisfaction. The improved satisfaction in the flipped classroom was predicted by the improvement in transactional distances between students, students and the instructor, and students and the instructional technology used in the class. The conclusions from this study suggest that the flipped classroom is a particularly good pedagogical strategy for quantitative classes. It allows the instructor to increase student satisfaction (a win for the students) in a course in which it is usually low without compromising academic standards (a win for the teachers). Finally, increased satisfaction leads to increased retention and hence increased revenues for the institution, which is a win for the administration.     

Classroom environments and student empowerment: An analysis of elementary and secondary teacher beliefs

This project explored a classroom model of motivation in which the source of student motivation is based on internal mechanisms or structures and classroom student/instructor interactions. It also extended earlier research in which beliefs of veteran, entry level, and preservice teachers have been explored. For this project, 117 elementary teachers (Grades K–5) with at least 3 years of experience and 126 secondary teachers (Grades 6–12) with similar teaching experiences completed a 40-item Likert-type questionnaire that focused on the four classroom dimensions of Affirmation, Rejection, Student Empowerment, and Teacher Control. The results suggested that elementary teachers and secondary teachers varied in their reported desire for teacher empowerment versus student empowerment in the classroom, and for providing a positive classroom environment as opposed to one that encourages a classroom atmosphere of rejection. Implications for future research and the need for creating affirming, empowering, motivational classroom environments are discussed.     

Student Perceptions of Chemistry Laboratory Learning Environments, Student–Teacher Interactions and Attitudes in Secondary School Gifted Education Classes in Singapore

This study investigated the chemistry laboratory classroom environment, teacher–student interactions and student attitudes towards chemistry among 497 gifted and non-gifted secondary-school students in Singapore. The data were collected using the 35-item Chemistry Laboratory Environment Inventory (CLEI), the 48-item Questionnaire on Teacher Interaction (QTI) and the 30-item Questionnaire on Chemistry-Related Attitudes (QOCRA). Results supported the validity and reliability of the CLEI and QTI for this sample. Stream (gifted versus non-gifted) and gender differences were found in actual and preferred chemistry laboratory classroom environments and teacher–student interactions. Some statistically significant associations of modest magnitude were found between students' attitudes towards chemistry and both the laboratory classroom environment and the interpersonal behaviour of chemistry teachers. Suggestions for improving chemistry laboratory classroom environments and the teacher–student interactions for gifted students are provided.

Activating learning in engineering education using ICT and the concept of ‘Flipping the classroom’

ABSTRACT

This case study trialled the introduction of a student-response system (Top Hat) in a third-year engineering Fluid Mechanics course (n?=?44) to improve student engagement, motivation and cognition. It was recognised that for the potential benefits of student-response systems (SRSs) to be fully realised, more time must be allocated for student engagement and the active learning components of the course. In order to allow sufficient time to fully engage with the SRSs and other classroom activities, traditional lectures were revised and the classroom format was flipped. This paper presents the initial case study results focusing on the use of SRSs. Overall, the new flipped lecture and SRS teaching format demonstrated a substantial increase in the level of student engagement, motivation, active learning and attendance compared to previous cohorts. However, the increased levels of engagement did not appear to reflect on any large increase in students’ individual grades.     

Beginning literacy: links among teacher knowledge, teacher practice, and student learning

Although the importance of phonological awareness has been discussed widely in the research literature, the concept is not well understood by many classroom teachers. In the study described here, we worked with groups of kindergarten and first-grade teachers (the experimental group) during a 2-week summer institute and throughout the school year. We shared with them research about learning disabilities and effective instruction, stressing the importance of explicit instruction in phonological and orthographic awareness. We followed the experimental group and a control group into their classrooms for a year, assessing teachers' classroom practices and their students' (n = 779) learning. The study yielded three major findings: We can deepen teachers' own knowledge of the role of phonological and orthographic information in literacy instruction; teachers can use that knowledge to change classroom practice; and changes in teacher knowledge and classroom practice can improve student learning.     

The Quality and Impact of Relationships between Elementary School Students and Teachers

The purpose of the present study was to begin to examine, from the expectancy-value framework, several cognitive and motivational variables believed to affect the development of the student/teacher relationship and, in turn, classroom success. Guided by the expectancy-value framework, three student variables are viewed as essential in guiding the success of the student/teacher relationship: (1) their social self-concept beliefs, (2) the value they place on developing a positive relationship with their primary teacher, and (3) their nonverbal communication skills. Eighty-two fourth- and fifth-grade students participated in the study. Variation in the students' perceptions of the quality of their relationship with their primary teacher and their classroom achievement were examined. In general, results suggest students develop schemas, their social self-concept beliefs, about their relationships with teachers that are consistent with their nonverbal communication skills. Furthermore, results suggest that for both positive perceptions of the relationship and academic achievement, valuing the relationship with the primary teacher may compensate for nonverbal difficulties.     

Toward a constructivist perspective: The impact of a mathematics teacher inservice program on students

A constructivist-oriented inservice program provided teachers of mathematics (K-12) with intensive two-week summer institutes and weekly classroom follow-up. Pre- and post-program data on student outcomes indicate that, along with transformations in the nature and quality of mathematics activity in the classroom, students' beliefs about learning mathematics changed and elementary students' attitudes toward mathematics improved. Although the instruction they now received focused more on conceptual understanding and less on computational skill, students' scores on standardized tests assessing routine knowledge were maintained.An earlier version of this paper appeared in R. Underhill (ed.),Proceedings of the Thirteenth Annual Meeting of the North American Chapter of the International Group for the Psychology of Mathematics Education 1, 43–49, Backsburg, VI.     

The effect of sharing health information on teachers' production of classroom accommodations

Ninety elementary‐school teachers read information about a hypothetical student experiencing school‐related problems due to Type 1 diabetes mellitus (T1DM), generated classroom accommodations to assist the student, and rated their confidence in these accommodations. Each teacher was provided one of three levels of information about T1DM: (a) no disease information, (b) basic disease information, and (c) basic disease information + classroom implications. Providing teachers with more information about T1DM increased their ability to accommodate a student's learning needs. Similarly, a lower proportion of disease‐specific accommodations were generated by teachers receiving no disease information (37%) than by teachers receiving basic disease information or basic disease information + classroom implications, and the later two groups were equivalent (47% for each). This study and future work concerning the effect of chronic illness on classroom performance and adjustment have implications for medical professionals, teachers, and school psychologists. © 2006 Wiley Periodicals, Inc.

Teacher and student usage of science textbooks

This study examines the differences between teachers' and students' perceptions of textbook usage in the science classroom. Four categories of use were identified: teacher directed student activities; teaching/studying guidance; as a source of information for the user and as preparation for assessment. The results of the study show that differences do occur between teachers and students with respect to their perceptions of the extent to which textbooks are used in the classroom and the purposes for which they are used, namely as a teaching/studying guide and as preparation for assessment. The findings of the study should be important to all those who use, write and publish high school science textbooks. Specializations: science education.     

Teacher–student talk in Singapore Chinese language classrooms: a case study of initiation/response/follow-up (IRF)

In this article, I analyse the initiation/response/follow-up (IRF) exchanges between teachers and students in teacher-fronted instruction by using transcribed classroom data. Adopting a social constructivist position, I examine ways in which teachers construct or reduce students' learning opportunities in these communications. Furthermore, I demonstrate how language is used to serve the functions of mediation and to provide learning opportunities. Although teachers talk most of the time and control most of the turns, I argue that teachers can improve their talk and control in their fronted instruction to optimise student contributions and to facilitate students' learning.     

A Self-Study of a Thai Teacher Educator Developing a Better Understanding of PCK for Teaching about Teaching Science

In this study, I, the first author as a Thai teacher educator employed self-study as a research methodology to investigate my own understandings, questions, and curiosities about pedagogical content knowledge (PCK) for teaching science student teachers and the ways I engaged student teachers in a field-based science methods course designed to help them to develop their PCK. Qualitative data gathered included: the syllabi, handouts, work submitted by student teachers, student teachers’ journal entries, my journal entries, and video recordings of my classroom teaching. Data were analysed using an inductive process to identify ways in which I attempted to enhance student teachers’ PCK. The contributions of this study are insights generated to help teacher educators think about how to support and develop student teachers’ PCK. Some of these contributions are enhancing teacher educators’ PCK for teaching science teachers, developing PCK for teaching science, and designing a science methods course in science teacher preparation programmes.
