Student outcomes and perceptions of instructors' demands and support in online and traditional classrooms 总被引:1,自引:0,他引:1
In this study, seven graduate students were interviewed and 187 (91 online; 96 traditional) graduate students were surveyed about perceptions of differences in instructors' demands and support and student' motivation, self-regulation, satisfaction, and perceptions of learning in these environments. Results indicated significant differences in students' perceptions on all variables except self-efficacy. Results indicated a strong effect for differences between perceived instructor affective support in online and traditional classrooms. Although students in traditional classrooms ranked instructors' affective support higher, the variable had a stronger relationship with online students' satisfaction. Differences between online and traditional students' reports of instructors' academic support, instructors' demands, and students' satisfaction were significant with medium effect sizes. Results are important because they provide information about students' perceptions of the differences in environments created by instructors that relate to students' affective outcomes. 相似文献

Scientific argumentation is an important learning objective in science education. It is also an effective instructional approach to constructivist science learning. The implementation of argumentation in school settings requires science teachers, who are pivotal agents of transforming classroom practices, to develop sophisticated knowledge of argumentation. However, there is a lack of understanding about science teachers’ knowledge of argumentation, especially the dialogic meaning of argumentation. In this case study, we closely examine a high school physics teacher’s argumentation-related pedagogic content knowledge (PCK) in the context of dialogic argumentation. We synthesize the teacher’s performed PCK from his argumentation practices and narrated PCK from his reflection on the argumentation practices, from which we summarize his PCK of argumentation from the perspectives of orientation, instructional strategies, students, curriculum, and assessment. Finally, we describe the teacher’s perception and adaption of argumentation in his class. We also identity the barriers to argumentation implementation in this particular case and suggest solutions to overcome these barriers. 相似文献

The purpose of this study was to provide an opportunity for science teachers to listen to adolescent girls discuss their ideas and feelings about the contemporary structure of middle-level science education. The reflections of these teachers were then analyzed to capture how the teachers interpreted what adolescent girls had to say and the action that they will take in the classroom as a result of those interpretations. This qualitative study investigated 11 teachers and 51 Grade 7 and 8 girls from various states across the continental USA. The girls discussed such things as their favorite science topics, comfort level in science classrooms, and curiosities about the physical world. The study revealed that adolescent girls strive to make a connection to science. They can see how science can help them to understand better themselves and their world, but they seldom find such understandings in contemporary science classrooms. In addition, adolescent girls not only need to have choices in their studies, but they understand that need. The study revealed that the teachers interpreted the girls' request from an assimilative perspective by seeking ways to help the girls fit into the existing structure of science education. The implications of the study suggest that science education will need to change in response to the voices of the others, but that change will only happen if we prepare teachers better to be prepared to listen and change practice in light of what they hear. 相似文献

Though research has shown that students do not have adequate understandings of nature of science (NOS) by the time they exit
high school, there is also evidence that they have not received NOS instruction that would enable them to develop such understandings.
How early is “too early” to teach and learn NOS? Are students, particularly young students, not capable of learning NOS due
to developmental unreadiness? Or would young children be capable of learning about NOS through appropriate instruction? Young
children (Kindergarten through third grade) were interviewed and taught about NOS in a variety of contexts (informal, suburban,
and urban) using similar teaching strategies that have been found effective at teaching about NOS with older students. These
teaching strategies included explicit decontextualized and contextualized NOS instruction, through the use of children’s literature,
debriefings of science lessons, embedded written NOS assessments, and guided inquiries. In each context the researchers interviewed
students prior to and after instruction, videotaped science instruction and maintained researcher logs and field notes, collected
lesson plans, and copies of student work. The researchers found that in each setting young children did improve their understandings
of NOS. Across contexts there were similar understandings of NOS aspects prior to instruction, as well as after instruction.
There were also several differences evident across contexts, and across grade levels. However, it is clear that students as
young as kindergarten are developmentally capable of conceptualizing NOS when it is taught to them. The authors make recommendations
for teaching NOS to young children, and for future studies that explore learning progressions of NOS aspects as students proceed
through school. 相似文献

The dramatic growth in the number of children learning English as a second language in our country has led to a corresponding
increase in the need to understand how teachers and schools can effectively teach children who are learning English as a second
language. Many teachers report not feeling prepared to meet the needs of these children (National Center for Education Statistics,
Teacher preparation and professional development: 2000. , 2002). The current study used focus group interviews to examine how Head Start teachers in one program addressed the special learning
needs of children learning English in their classrooms. Key challenges involved communicating with children and their families
in their home language. Teachers used other staff, parents, and children in the classroom to interpret. Strategies involved
visual aids, pictures, gestures, and a welcoming classroom environment. Resources used by teachers were professional development
and language skills of other staff. However, available resources were often underutilized and limited for teachers to use
in meeting the challenges the teachers faced in the classroom. Suggestions are presented for overcoming the challenges and
limited resources encountered by teachers, such as changes in preservice and inservice training opportunities, and second
language learning opportunities for teachers. Further implications for training and research are discussed. 相似文献

The purpose of this study was to examine the extent to which three teachers’ professional experience and existing orientations
toward teaching and learning mathematics and science influenced their implementation of a project-based curriculum (i.e. project-based
learning (PBL)). Data sources included interviews, videotapes of classroom activity, and a teaching philosophy questionnaire.
Data analysis was conducted using an iterative coding technique. We found coherency between the teachers’ perceived orientations
and their emergent ideas about PBL, their sense of PBL as being compatible with their goals, and the specific challenges with
which they struggled. All the teachers wanted their students to be successful; however, different definitions of success led
to quite different approaches toward teaching, and for the most part, these differences appeared to have occurred because
of existing orientations the teachers held for teaching their discipline. Implications for professional development taking
into account teachers’ orientations and thus their professional experience are discussed, as well as disciplinary challenges
to using PBL. 相似文献

Prenatal depression, violence, substance use, and perception of support in pregnant middle-class women 下载免费PDF全文
The purpose of this study was to explore the vulnerability for postpartum depression among financially, educationally, and socially advantaged middle-class women (n = 31). Twenty-nine percent reported prenatal depression, 13% reported intimate partner violence, and 22% reported concerns with partner relationships and support expectations after delivery. No illegal substances were reported; however, a past history of smoking and excessive use of caffeine was disclosed. Implications for practice focus on the need to screen and implement intervention programs for these social problems and to adopt measures as a universal standard of care for all women, regardless of demographic advantages. 相似文献

Gamification is the use of game mechanics to drive game-like engagements and actions. It applies game mechanics, dynamics and frameworks to promote desired learning behaviours. Positive and effective gamification could enhance learning and engage learners in more social and context-rich decision-making for problem-solving in learning tasks. Effective gamification design should understand the game personalities of learners, social engagement styles, and intrinsic- and extrinsic-motivated user styles initially and evaluate and select appropriate game mechanics, game dynamics, to create ideal gamification instructions. The research question this study investigated is: How will four types of gaming personalities (i.e. Explorer, Socialiser, Killer and Achiever) predict the level of game dynamics in online discussion environments? This study concluded that examining how gaming personalities relate to game dynamics in a gamified online discussion instruction is not sufficient to design effective gamification. It suggests future studies in game instructions should focus on the relationships between game dynamics, gamification contexts, gaming personalities or preferences, dynamic gaming engagement styles, etc. 相似文献
