Teacher Clarifying Behaviors

High school social studies students (N = 448) were each assigned to one of 16 groups defined by possible combinations of two teacher uncertainty conditions (uncertainty vs. no uncertainty), two teacher “bluffing” conditions (bluffing vs. no bluffing), two lesson discontinuity conditions (discontinuity vs. no discontinuity), and two lecture notes conditions (notes handouts vs. no notes handouts). Each group was presented a lesson about the geography, politics, history, and economy of Botswana. The lessons were the same except for variations in the four conditions stated above. After the lesson, each group was tested on comprehension of the material, and then each group completed a lesson evaluation. Teacher uncertainty negatively affected achievement, and notes handouts positively affected achievement. Both teacher bluffing and lesson discontinuity negatively affected student evaluation of the lesson. Several significant interactions were obtained. These findings are discussed in relation to previous research on low-inference behaviors related to teacher clarity.     

Actual and perceived teacher clarity - relations to student achievement in science

College students (N = 41) were randomly assigned to one of two groups defined by the teacher's clarity in the lesson, i.e., high-clarity versus low-clarity presentation on genetics. After the lesson the subjects completed a test on the contents of the lesson and then rated the lesson presentation. Students in the high-clarity group achieved more (although not significantly) than students in the low-clarity group. Students perceived the high-clarity lesson as significantly clearer than the low-clarity lesson. These findings are discussed in relation to previous research on teacher clarity.     

Student ability in identifying reasons for different points of view: A learning activity conducted with a group of Japanese High School Students

Problem solving as a skill is emphasized within the revised Japanese Course of Study for schools. This experimental study, conducted among Japanese high school students, evaluates an effort to develop student ability to identify reasons fordifferent points of view, not just personally favored views. First, the ability of all students was tested using a reading literacy question from the 2000 PISA test, which measures the reading skills of evaluation and reflection. The experimental group then participated in a developmental learning activity. After the activity, all students were retested using the same PISA question. Nothing conclusive was found regarding the general effectiveness of the lesson activity, but two insights were gained. It was found that student self-awareness of the importance of the learning task and interactive learning are important to consider.     

Teacher, self and peer evaluation of lesson plans written by preservice teachers

The study investigated the effects of three types of evaluation on preservice teachers’ performance, knowledge and attitudes related to writing lesson plans that incorporate technology. Subjects were randomly assigned to one of the three treatment conditions: teacher-evaluation, self-evaluation or peer-evaluation. All groups completed three class periods of instruction on writing lesson plans, then each subject submitted his/her draft lesson plan. The drafts were evaluated by assigned evaluators (teacher, self or peer), who provided scores and written feedback on a 15-item rubric. Students then revised their lesson plans into final form. All three treatment groups improved their lesson plans significantly from draft version to final version, with the teacher-evaluation group showing significantly greater improvement and writing significantly better final lesson plans than each of the other two groups. Teacher-evaluation and self-evaluation groups had significantly higher scores on a knowledge-based posttest than the peer-evaluation group. Several suggestions are discussed for making further improvements in the self-evaluation and peer-evaluation processes.     

High-structure versus low-structure cooperative learning in introductory psychology classes for student teachers: Effects on conceptual knowledge,self-perceived competence,and subjective task values

Using group presentation classes as a control condition, in nine introductory psychology classes we examined the impact of high-structure versus low-structure cooperative learning on N = 259 student teachers' conceptual knowledge, on their self-perceived competence, and on their appraisals of task values. To vary the structure, we first created a lesson plan built upon core principles of cooperative learning, and then eliminated from this plan critical elements structuring students' shared learning. Two-level analyses revealed that students in the two cooperative conditions (a) did better on three knowledge tests administered throughout the course of this one-semester project, (b) developed a more favorable view of their subject-specific competence, and (c) appraised the utility and intrinsic value of task assignments more positively than did the control students. In each of the three knowledge tests, students in high-structure groups outperformed students in low-structure groups. These findings support the hypothesis that structuring procedures enhance the efficaciousness of cooperative learning methods in college classes.     

The effects of a short-term professional development program on physical education teachers’ behaviour and students’ engagement in learning

This study examined the effect of a short-term training programme οn in-service physical education teachers’ behaviour and students’ engagement in learning. Teachers (n = 32) were randomly divided into an experimental and a control group. Each teacher’s behaviour was observed in six lessons; two for each measurement (pre, post and retention) and analysed with qualitative dimensions of lesson introduction, task presentations and lesson closure. Student engagement was analysed with the time analysis form. The total and successful attempts of selected students were also recorded. The experimental group attended a two-hour lecture followed by a two-hour practicum, and showed significant improvement and learning of all the examined behaviours as well as significantly higher performance than the control group. Also, students of the experimental teacher group presented significantly greater activity time, more practice attempts and more successful ones than their peers in the control group. The results establish the effect of the training programme on teacher behaviour and student engagement in learning.     

Informal learning: Student achievement and motivation in science through museum-based learning

This study examined changes in student motivation and achievement in science during a visit to a university children’s science museum. The study was based on the pretest–posttest control comparison group design with four treatment groups: control, exhibit, lesson and exhibit/lesson. The sample consisted of 228 sixth-grade students from a Louisiana public school who were randomly assigned to one of the four experimental groups. Pretest, posttest and delayed posttest measures of intrinsic motivation and achievement in science were obtained using the Children’s Academic Intrinsic Motivation Inventory and an achievement test written to measure areas of science incorporated in the museum exhibits. The data were analysed using a one-way ANOVA, dependent t tests and Pearson r. Significant differences were found within groups for (1) the lesson group in motivation and (2) the exhibit group in achievement from pretest to posttest and from posttest to delayed posttest. A significant relationship between level of motivation and science achievement was revealed for the exhibit group on the delayed posttest. There were no other significant findings to support that the treatment led to any long-term effects on motivation or achievement within any of the four experimental groups.     

Proximal Versus Distal Validity Coefficients for Teacher Observational Instruments

This study examined the use of measures of student learning computed using end-of-year assessments (distal measures) versus measures of student learning associated with a single lesson (proximal measures) as criterion scores for the validity of observations of teachers' pedagogical skills. The validity coefficients computed using distal measures were significantly lower than the validity coefficient computed using proximal measures. Assumptions underlying the current emphasis on distal measures were challenged. Possible ways to generate more proximal measures were explored.     

Learning molecular behaviour may improve student explanatory models of the greenhouse effect

We assessed undergraduates’ representations of the greenhouse effect, based on student-generated concept sketches, before and after a 30-min constructivist lesson. Principal component analysis of features in student sketches revealed seven distinct and coherent explanatory models including a new Molecular Details model. After the lesson, which described the invisible molecular behaviour of gases, this group (n = 164) produced significantly more expert-like representations of the greenhouse effect, and included fewer novice ideas. The key behaviour that greenhouse gases emit radiation in random directions is new to most students and directly counters common explanations involving reflection and ‘trapping’ of radiation in the atmosphere. Thus, learning molecular behaviour of greenhouse gases may help students replace non-expert explanatory models. This Molecular Details model has not been previously identified, and is unlikely to have emerged from human evaluation of student sketches alone. When teaching the greenhouse effect, we propose that interventions explicitly incorporate greenhouse gas behaviour.     

Students' engagement in a science classroom: Does knowledge diversity matter?

Knowledge diversity describes group members' differences in terms of prior knowledge in a domain. The purpose of the study was to investigate whether knowledge diversity would impact students' engagement in small-group learning in a science classroom. A total of 45 seventh-grade students were recruited to participate in the study in which two experimental conditions were compared: low-prior-knowledge groups (all low-prior-knowledge students) versus mixed knowledge groups (low-prior-knowledge students with one knowledgeable student). Participates were randomly assigned into six low-prior-knowledge groups (24 individuals in total) and five mixed knowledge groups (21 individuals in total). Engagement, as well as group performance, was measured. The results of a series of independent-samples t test demonstrated that the mixed knowledge groups had significantly higher behavioral, emotional, and social engagement and better group performance than did the low-prior-knowledge groups. This implies that even having one knowledgeable student could enhance students' engagement in a science classroom.     

小学数学课堂教学评价的质性研究

Through the qualitative interviews of five implementers of primary school mathematics curriculum, this study addresses the ways in which mathematics lessons are evaluated. Results show that each evaluator recognizes different aspects of a “good lesson,” however, among all criteria, the design of the lesson plan, realization of the lesson goals, active student participation, and mathematical thinking are seen as key indicators in lesson evaluation. The study also shows that student performance is a major point of concern in lesson evaluation, and some extreme teaching practice has drawn attention and being reflected by some implementers of the New Mathematics Curriculum.     

Student teachers' reasoning while making pedagogical decisions

SUMMARY This study examines student teachers' reasoning when making pedagogical decisions at two stages of the teaching process: the pre-active stage of lesson planning and the post-active stage of analysis of the lesson taught. The sample consisted of 21 student teachers, all with a BA degree but no teaching certificate, already teaching various subjects in secondary schools. The student teachers took a course in pedagogy, during which they gained experience in planning lessons and teaching them by means of peer teaching. Qualitative and quantitative findings were gathered from the student teachers' reflective journals. Findings relate to: (1) the topics figuring in their pedagogical decisions; (2) the arguments used to explain the decisionss; and (3) the range of arguments given for each decision. The importance of the study lies in identifying student teachers' reasoning when planning and teaching lessons, highlighting specific shortcomings, in view of the complexity of teaching situations. The study yielded insights relevant to the educational process.     

Guided work-based learning: Sharing practical teaching knowledge with student teachers

Building quality work-based learning opportunities for student teachers is a challenge for schools in school-university partnerships. This study focused on the guidance of student teachers by means of a mentoring approach aimed at sharing practical knowledge, with student teachers’ learning needs as an emphasis. The approach was built on collaborative lesson planning, enactment, and evaluation.The study followed three triads (student teacher, mentor, school-based teacher educator) and examined participants’ appreciation of the effectiveness of the approach and their perception of relevant conditions. The approach was considered effective: deeper conversations appeared and new issues emerged earlier than in regular mentoring conversations.     

Some reflections on mathematics classroom notebooks and their relationship to the public and private nature of student practices

This article considers students' classroom notebooks, their character and their role in learning. The results presented were found within the frame work of a broader international project, the Learners Perspective Study, whose goal is to identify classroom practice from the students' point of view. Two 8^thgrade classrooms were studied. In each,every lesson over the course of three weeks was videotaped. After each lesson, two students were interviewed and their notebooks entrees for that lesson were photocopied; once a week, the teacher was interviewed as well. From the analysis of the data it became apparent that the notebook in the classroom is a publicobject; it is ever open for inspection and contains only finished work. That it is not a private object in which the student may freely record preliminary ideas, musings, and reflections may affect student learning negatively. The categorization of public and private as a categorization of learning activities is discussed. The relationship between the findings on notebooks and research on writing and classroom journals is discussed; in particular, a connection is made between public and private domains and transactional and expressive writing,respectively. This revised version was published online in July 2006 with corrections to the Cover Date.     

Teacher Talk During Whole‐Class Lessons: Engagement Strategies to Support the Verbal Participation of Students with Learning Disabilities

The analysis identified discursive strategies used by general education teachers in inclusion classrooms to orchestrate and scaffold the verbal participation of all students, including students with learning disabilities (LD). The context was writing instruction. A whole‐class lesson involving teacher–student collaboration to write a text was analyzed for each of two teachers in two urban elementary inclusion classrooms totaling 67 students; 23 students had LD. Analysis of teacher talk focused on procedural strategies (help the lesson run smoothly and make it easier to follow) and involvement strategies (elicit students' attention to and participation in the lesson). Results indicated that both teachers used a variety of similar strategies to provide spaces for student contributions and, at the same time, move the lessons along. However, they also used contrasting strategies unique to their contrasting pedagogical frames of reference (structural vs. interactional).     

Enhancing in-service teachers’ professional learning through a school-based professional development programme in Hong Kong

ABSTRACT

Lesson study is a collaborative model of professional development that provides teachers with the opportunity to learn from the planning, conduction and reflection of a specifically designed research lesson. Lesson study is increasingly incorporated in initial teacher education (ITE) and calls have been made to further detail the lesson study structures that support student teacher learning. In this paper the core organisational elements of incorporating lesson study in ITE are investigated as a comparative case study situated in two distinct educational and cultural settings: one in Ireland (post-primary) and the other in Norway (primary). Qualitative data, including student teachers’ planning notes, research lesson designs, and observation notes from live research lessons, were analysed and findings reveal three structural factors for the incorporation of lesson study in ITE. First, defined roles of mentor and university teachers as knowledgeable others; second, the engagement of student teachers at each phase of lesson study, with the inclusion of case pupils; and third, the conduction of the lesson study cycle on both university campus and in the classroom. These findings contribute to the growing literature of lesson study in ITE and may support the inclusion of lesson study in ITE programmes.     

Using educational technology to develop early literacy skills in Sub-Saharan Africa

The research explores the impact of interactive, multimedia literacy software (ABRA) on the reading skills of early elementary students in Kenya. Twelve grade two English teachers and their students from six schools were randomly divided in half: an experimental group (N?=?180) where ABRA was part of their English Language instruction and a control group (N?=?174) where regular instruction was used. After the pre-test student data were collected, a three-day initial training and planning session were held for the experimental teachers on how to use ABRA to teach literacy. Every week each experimental class was bussed to a computer lab with full access to ABRA for one 90-min lesson. Teacher support included the alignment of ABRA lesson plans with the Kenyan English Language norms, weekly web conferences with the trainer, as well as technical and pedagogical help from staff at the lab site. After the 13-week intervention, significant and substantial gains in reading comprehension were found for ABRA students as measured by GRADE, a standardized test of literacy. In addition, ABRA students outperformed their peers in control classes on the core end-of-year subject exams including English, Mathematics, Science and Social Studies.     

Effects of teacher clarity and student anxiety on student outcomes

A laboratory experiment was carried out with 120 undergraduate students to examine a possible aptitude–treatment interaction between teacher clarity and student test anxiety in relation to two outcome measures, namely student achievement and student motivation, with student intelligence statistically controlled. Students completed measures of intelligence and test anxiety and were randomly assigned to high teacher clarity or low teacher clarity conditions, defined by the presence or absence of specific teaching behaviours in a videotaped lecture with content held constant across conditions. Measures of motivation and self-efficacy for learning the material were completed immediately post-treatment, then one week later participants completed an achievement test based on the material contained in the lecture and assigned homework. Results revealed significant beneficial main effects for high vs. low teacher clarity for both achievement and motivation measures, but no aptitude–treatment interaction between teacher clarity and student test anxiety.
