Determining the level of inquiry in teachers' questions     

George T. Ladd  Hans O. Andersen 《科学教学研究杂志》1970,7(4):395-400

The purpose of this investigation was to determine if an instrument, originally designed to classify levels of teachers' questions on the basis of logical operations, could be utilized to measure the level of inquiry present in a classroom discussion and to determine if the inquiry questioning behavior of the teacher influenced student achievement. The results of the study show that the modified classification scheme could accurately and reliably measure the inquiry level of teachers' classroom questions. The data also indicated that teachers who ask a greater proportion of high inquiry questions cause a greater change in students as measured by an achievement examination.  相似文献   

Child abuse: adolescent records vs. adult recall   总被引：4，自引：1，他引：4  

D Della Femina  C A Yeager  D O Lewis 《Child abuse & neglect》1990,14(2):227-231

In a follow-up study of incarcerated Connecticut youth, 69 subjects were interviewed during young adulthood. On follow-up, 26 gave histories of abuse discrepant with histories obtained from records and interviews conducted in adolescence. Eleven subjects agreed to an additional clarification interview, at which time they were apprised of the discrepancies. Of these, eight had adolescent records indicating that abuse had occurred but denied abuse during the adult follow-up interview. The remaining three had adolescent records indicating no abuse had ever occurred, but, on follow-up, reported having been abused. The additional clarification interviews revealed that all 11 subjects with discrepant histories had, in fact, been abused. Reasons for these discrepant data and strategies to enhance the investigator's ability to obtain accurate data regarding abuse are discussed.  相似文献

The recursive practice of research and teaching: reframing teacher education     

Rebecca Miles  Narelle Lemon  Donna Mathewson Mitchell  Jo-Anne Reid 《Asia-Pacific Journal of Teacher Education》2016,44(4):401-414

As a field, Teacher Education has lived with continued criticism from governmental and research bodies on the quality of professional preparation and the lack of a strong research base. We respond to such criticisms by considering possibilities for further exploration of the research of practice and the practice of research in both initial and continuing teacher education. As both a theoretical and methodological challenge, this is tied recursively with research and practice in teacher education, for teacher educators, about teacher education. We draw on the theoretical resources of practice theories, to argue that teacher education practice must be informed by the study of the practice of teaching as well as research addressing the teaching of practice. In conclusion, we make a methodological case for reframing the roles of teacher and researcher within a “thirdspace” to consider the practice of researching teaching as recursive and always regenerative.  相似文献   

The effect of concept mapping on students' anxiety and achievement in biology     

Olugbemiro J. Jegede  Folusho F. Alaiyemola  Peter A. O. Okebukola 《科学教学研究杂志》1990,27(10):951-960

The results of recent studies into the use of the concept mapping heuristic seem to demonstrate that meaningful learning results through its use in science classrooms. While this underscores the need to use more effective instructional strategies in science teaching, the issue of the intervening variable of anxiety in learning and science achievement, and the possible use of a metacognitive strategy in anxiety reduction have not been addressed. This study, therefore, sought to find out if the metacognitive strategy of concept mapping reduces anxiety and thereby enhances achievement in biology. A total of 51 (30 boys, 21 girls) senior secondary one (grade 10) students participated in this experiment. Two instruments—the Zuckerman Affect Adjective Checklist and the Biology Achievement Test—were used in pre- and posttest administrations to measure the treatment effect on anxiety and achievement, respectively. Findings support the stand that concept mapping is significantly more effective than the traditional/expository teaching strategy in enhancing learning in biology. In addition, it apparently reduces students' anxiety towards the learning of biology. A significant reduction of anxiety was noticed for male subjects.  相似文献   

Curriculum Design of a Flipped Classroom to Enhance Haematology Learning

A common trend in higher education is the “flipped” classroom, which facilitates active learning during class. The flipped approach to teaching was instituted in a haematology ‘major’ class and the students’ attitudes and preferences for the teaching materials were surveyed. The curriculum design was explicit and involved four major components (1) the preparation of the students; (2) the weekly pre-class work; (3) the in-class active learning strategies and (4) closing the learning loop using formative quizzes. Each of these components is discussed in detail and was informed by sound pedagogical strategies. Several different sources of information and several freely available software tools to engage the students are discussed. Two iterations are reported here, with improved pass rate for the final examination from 47 to 48 % in the traditional class to 56–65 % in the flipped classroom approach. The majority of students (93 and 89 %) came to the class prepared, after viewing the screencasts and engaged fully with the activities within the face-to-face time. The students perceived that solving case studies (93 %) was the most beneficial activity for their learning and this was closely followed by the production of essay plans (71 %). The majority of students recommended that this approach be repeated the following year (69 and 75 %).  相似文献   

A Methylome‐Wide Association Study of Trajectories of Oppositional Defiant Behaviors and Biological Overlap With Attention Deficit Hyperactivity Disorder          下载免费PDF全文

In 671 mother–child (49% male) pairs from an epidemiological birth cohort, we investigated (a) prospective associations between DNA methylation (at birth) and trajectories (ages 7–13) of oppositional defiant disorder (ODD), and the ODD subdimensions of irritable and headstrong; (b) common biological pathways, indexed by DNA methylation, between ODD trajectories and attention deficit hyperactivity disorder (ADHD); (c) genetic influence on DNA methylation; and (d) prenatal risk exposure associations. Methylome‐wide significant associations were identified for the ODD and headstrong, but not for irritable. Overlap analysis indicated biological correlates between ODD, headstrong, and ADHD. DNA methylation in ODD and headstrong was (to a degree) genetically influenced. DNA methylation associated with prenatal risk exposures of maternal anxiety (headstrong) and cigarette smoking (ODD and headstrong).  相似文献

Pre-service physical education teachers’ Indigenous knowledge,cultural competency and pedagogy: a service learning intervention     

Louisa R. Peralta  Donna O’Connor  Wayne G. Cotton  Andrew Bennie 《Teaching Education》2016,27(3):248-266

In this paper, we investigate the effects of a community- and school-based service learning experience (SLE) on pre-service physical education teachers’ Indigenous knowledge, cultural competency and pedagogy. Informed by the theoretical tenets of Indigenous research methodologies, experiential learning and critical reflection, we examine 55 final-year pre-service physical education teachers’ (age: 21.9 [8.3]; 10.7% low SES; 68% females) cultural learning and competency in a core unit of study with a six-week SLE. Measures of their experiences included reflective journals, multicultural teaching competency scales and focus group interviews. Findings support the design of the SLE, with statistically significant changes in pre-service teachers’ perceptions of their cultural competency (p < 0.001). Pre-service teachers were able to challenge their assumptions about Indigenous students, plan and implement student-centred and culturally relevant pedagogies. Attention is drawn to the design of this SLE and demonstrates the importance of using Indigenous community members and teachers as mentors, which has not been explored in previous SLE studies.  相似文献   

Improving the learning of Boolean queries by means of a multiobjective IQBE evolutionary algorithm     

O. Cordón  E. Herrera-Viedma  M. Luque 《Information processing & management》2006

The Inductive Query By Example (IQBE) paradigm allows a system to automatically derive queries for a specific Information Retrieval System (IRS). Classic IRSs based on this paradigm [Smith, M., & Smith, M. (1997). The use of genetic programming to build Boolean queries for text retrieval through relevance feedback. Journal of Information Science, 23(6), 423–431] generate a single solution (Boolean query) in each run, that with the best fitness value, which is usually based on a weighted combination of the basic performance criteria, precision and recall.  相似文献
