A case study of a contemporary secondary school English teacher is presented and compared with prior research about teacher planning. Drawing on his rich content knowledge, this teacher's long-range pre-active planning is his major form of planning when he develops interconnected themes for the course, selects literature, and develops curriculum materials for it employing technology. Because this case differs substantially from prior research, a call is made for more studies of teacher planning. 相似文献

Librarians who teach one-shot library instruction classes (one-time, one- to three-hour classes to students who are assumed to be novice researchers) are often torn between two pedagogic approaches: a “critical mass” pedagogy emphasizing a minimum amount of databases that must be introduced with little time for student searching, and a “use-oriented” pedagogy emphasizing the introduction of one or two databases, with the instructor providing adequate time for the student to hone their search skills through in class work time that provides for interaction with the librarian. Drawing from the learning theory of Brian Cambourne, we compare the two pedagogic approaches and argue that a use-oriented approach is a better match to Cambourne's Conditions of Learning, but that without certain preparations of and expectations from the student, librarians will struggle with both approaches in these one-shot library instruction sessions. 相似文献

The purpose of this study was to identify and test the influences that lead individuals to actively manage the meaning of a company Mission Statement. Communication about a company Mission Statement was hypothesized to be a function of an individual's information environment, level of work unit commitment, trust in management, and organizational role. The Management of Meaning Scale (MMS) was developed to assess specific meaning management behaviors. The MMS was cast as the chief dependent variable in a path analysis using LISREL. The general model was well supported. Implications for practices associated with Mission Statement implementation are discussed. 相似文献

A bidimensional acculturation framework cannot account for multiple destination cultures within contemporary settlement societies. A tridimensional model is proposed and tested among Jamaican adolescent–mother dyads in the United States compared to Jamaican Islander, European American, African American, and other Black and non‐Black U.S. immigrant dyads (473 dyads, M adolescent age = 14 years). Jamaican immigrants evidence tridimensional acculturation, orienting toward Jamaican, African American, and European American cultures. Integration is favored (70%), particularly tricultural integration; moreover, Jamaican and other Black U.S. immigrants are more oriented toward African American than European American culture. Jamaican immigrant youth adapt at least as well as nonimmigrant peers in Jamaica and the United States. However, assimilated adolescents, particularly first generation immigrants, have worse sociocultural adaptation than integrated and separated adolescents. 相似文献

Professional Learning Communities (PLCs) are frequently being used as a vehicle to transform science education. This study explored elementary teachers' perceptions about the impact of participating in a science PLC on their own professional development. With the use of The Science Professional Learning Communities Survey and a semi-structured interview protocol, elementary teachers' perceptions of the goals of science PLCs, the constraints and benefits of participation in PLCs, and reported differences in the impact of PLC participation on novice and experienced teachers were examined. Sixty-five elementary teachers who participated in a science PLC were surveyed about their experiences, and a subsample of 16 teachers was interviewed. Results showed that most of the teachers reported their science PLC emphasized sharing ideas with other teachers as well as working to improve students' science standardized test scores. Teachers noted that the PLCs had impacted their science assessment practices as well as their lesson planning. However, a majority of the participants reported a differential impact of PLCs depending on a teacher's level of experience. PLCs were reported as being more beneficial to new teachers than experienced teachers. The interview results demonstrated that there were often competing goals and in some cases a loss of autonomy in planning science lessons. A significant concern was the impact of problematic interpersonal relationships and communication styles on the group functioning. The role of the PLC in addressing issues related to obtaining science resources and enhancing science content knowledge for elementary science teachers is discussed. 相似文献

ABSTRACTCrosscutting concepts such as scale, proportion, and quantity are recognised by U.S. science standards as a potential vehicle for students to integrate their scientific and mathematical knowledge; yet, U.S. students and adults trail their international peers in scale and measurement estimation. Culturally based knowledge of scale such as measurement units may be built on evolutionarily-based systems of number such as the approximate number system (ANS), which processes approximate representations of numerical magnitude. ANS is related to mathematical achievement in pre-school and early elementary students, but there is little research on ANS among older students or in science-related areas such as scale. Here, we investigate the relationship between ANS precision in public school U.S. seventh graders and their accuracy estimating the length of standard units of measurement in SI and U.S. customary units. We also explored the relationship between ANS and science and mathematics achievement. Accuracy estimating the metre was positively and significantly related to ANS precision. Mathematics achievement, science achievement, and accuracy estimating other units were not significantly related to ANS. We thus suggest that ANS precision may be related to mathematics understanding beyond arithmetic, beyond the early school years, and to the crosscutting concepts of scale, proportion, and quantity. 相似文献

Graduate teaching assistants (GTAs) are gaining increasing responsibility for the instruction of undergraduate science students, yet little is known about their beliefs about science pedagogy or subsequent classroom practices. This study looked at six GTAs who were primary instructors in an introductory biology laboratory course. Teaching assistants taught a lesson about the potential social, health, and environmental impacts of genetically modified crops. Through classroom observations and in‐depth interviews, the researchers examined how instructors chose to frame their lessons and what GTAs perceived as important for students to know about this particular socioscientific issue (SSI). Results showed a disconnect between the relatively mature conceptualizations of effective SSI instruction that emerged during interviews and classroom practice. 相似文献
