Pedagogical content knowledge (PCK) is a type of teacher knowledge to be developed by a teacher. PCK is said to contribute to effective teaching. Most studies investigated the development of PCK and its influence on students’ learning from the teachers’ perspectives. Only a limited number of studies have investigated the components of science teachers’ PCK that helped students’ learning from the perspective of students. Thus, it is the aim of this study to investigate the level of science teachers’ PCK from students’ perspective, in particular whether or not students of different achieving ability had different views of teachers’ PCK in assisting their learning and understanding. Based on the PCK research literature, six components of PCK have been identified, which were as follows: (1) subject matter knowledge, (2) knowledge of teaching strategies, (3) knowledge of concept representation, (4) knowledge of teaching context, (5) knowledge of students, and (6) knowledge of assessment in learning science. A questionnaire consisting of 56 items on a five-point Likert-type scale were used for data collection from 316 Form Four students (16 years old). One-way analysis of variance revealed that the differences in science teachers’ PCK identified by students of different achieving abilities were statistically significant. Overall, students of various academic achieving abilities considered all the components of PCK as important. The low-achieving students viewed all the components of PCK as being less important compared to the high and moderate achievers. In particular, low-achieving students do not view ‘knowledge of concept representation’ as important for effective teaching. They valued the fact that teachers should be alert to their needs, such as being sensitive to students’ reactions and preparing additional learning materials. This study has revealed that PCK of science teachers should be different for high and low-achieving students and knowledge of students’ understanding plays a critical role in shaping teachers PCK. 相似文献

This paper is a report of a survey conducted to determine teachers’ perception of the science laboratory learning environment and the relationship between different aspects of this environment and satisfaction from teaching and learning. Teachers’ perceptions of psychosocial aspects were measured by use of the Science Laboratory Environment Inventory (SLEI), whereas perceptions of physical aspects were measured by use of the Physical Science Laboratory Environment Inventory. The level of satisfaction was measured by use of a satisfaction scale (SC). Data were collected from 800 science teachers in secondary schools in Malaysia. Analysis of findings revealed that teachers have positive attitudes on all SLEI scales, with the exception of the open-ended scale. In terms of physical aspects, teachers regard lighting and technology as highly important but furniture and equipment, space, air quality and safety as of moderate importance only. Results also showed that teachers’ satisfaction from teaching in the laboratory was positive. Subsequent analysis revealed a significant predictive relationship between teachers’ perception of science laboratory learning environments and their teaching and learning satisfaction. 相似文献

Intelligent learning systems (ILSs) have evolved in the last few years basically because of influences received from multi-agent architectures (MAs). Conflict resolution among agents has been a very important problem for multi-agent systems, with specific features in the case of ILSs. The literature shows that ILSs with cognitive or pedagogical agents are prone to arbitration methods, where as ILSs with reactive agents are much in favor of control mechanisms. For these kind of systems, different control types are proposed based on the different stimuli that these agents will receive. These stimuli are aspects to be evaluated during the teaching/learning process such as: (1) error analysis, (2) learning styles, (3) analogies, (4) social aspects, etc. The paper reviews several ILSs, related to our work; different control mechanisms are proposed to solve the agents' intervention conflicts. Finally, the use of several mechanisms is exemplified by the results of a specific ILS. 相似文献

This study investigated the understanding of science process skills (SPS) of 329 science teachers from 52 primary schools selected by random sampling. The understanding of SPS was measured in terms of conceptual and operational aspects of SPS using an instrument called the Science Process Skills Questionnaire (SPSQ) with a Cronbach’s alpha reliability of 0.88. The findings showed that the teachers’ conceptual understanding of SPS was much weaker than their practical application of SPS. The teachers’ understanding of SPS differed by their teaching qualifications but not so much by their teaching experience. Emphasis needs to be given to both conceptual and operational understanding of SPS during pre-service and in-service teacher education to enable science teachers to use the skills and implement inquiry-based lessons in schools. 相似文献

College students experience great stress due to many factors, such as an uncertain future, academic responsibilities, and pressures imposed by social communication. Many institutions of higher education are focusing on how to mediate stressful situations and increase the subjective well-being (SWB) of students to sustain a lifestyle focused on wellness. The online survey used for this study focused on testing an exploratory SWB model by implementing partial least squares structural equation modeling (PLS-SEM) techniques. The participants were 470 college-aged students enrolled in seven different institutions in six cities across China. Findings yielded a good model fit (the Standardized Root Mean Squared Residual [SRMR] = .054) with the validity of manifest variables, reliability of the latent variables (LVs), and overall SWB model indicating moderate predictiveness (GoF R2 = .476) by the LVs. Additionally, all of the direct path coefficients and indirect path coefficients that consisted of four partial mediators and one full mediator yielded statistically significant results via bootstrapping. Furthermore, path coefficients for utilization of emotion to life satisfaction for the cognitive exercise group were significantly higher than for the non-cognitive exercise group. The findings illustrated a good model fit for an exploratory SWB model that can predict an individual’s SWB, and cognitive and non-cognitive exercises had different effects on the individuals’ SWB. 相似文献

One hundred thirty-two graduates with learning disabilities (LD) of a large, public, competitive postsecondary institution were surveyed to determine if they had self-disclosed their LD to their current employer and to provide the reasons for choosing to self-disclose or not to self-disclose. Based on a response rate of 67.4% (n = 89), the results indicated that 86.5% of the respondents were employed full time. Although nearly 90% of the respondents stated that their LD affected their work in some way, only 30.3% self-disclosed to their employer. Of those who had not self-disclosed, the majority reported that there was no reason or need to self-disclose. However, 46.1% reported not self-disclosing due to fear of a potentially negative impact in the workplace or due to a concern for job security. Specific rationales for disclosure and information related to the use of self-reported accommodations and strategies are presented. 相似文献

The complexity of science teaching requires science teachers to encounter a range of tasks. Some tasks are perceived as stressful while others are not. This study aims to investigate the extent to which different teaching situations lead to different stress levels. It also aims to identify the easiest and most difficult conditions to be regarded as stressful conditions by science teachers. An occupational stress inventory of 25 items developed by Okebukola (1988) validation of the occupational stress inventory for science teachers. Science Teacher, was used to measure the science teachers’ stress level in science teaching. A four point Likert scale ranging from 1 – ‘no stress at all’ to 4 – ‘extreme stress’ was used. Fifty-eight Malaysian secondary science teachers participated in the survey in which six volunteered to participate in the interview study. The data was then analyzed using the Rasch model to measure the level of stress caused by different kinds of stressful conditions. Even though ‘overloaded science syllabus’ was identified to be the basis of multiple stressful conditions, it was, however, difficult for the respondents to regard it as a stressful condition. On the other hand, the respondents found that ‘having to teach difficult science topics’ is easiest to be regarded as a stressful condition. It was shown that even though ‘overloaded science syllabus’ is the starting point for stress caused by multiple conditions, due to the availability of coping strategies which can be employed by the respondents, the stressor is minor in causing stress among teachers. On the other hand, when teachers lack the availability of coping strategies dealing with teaching difficult science topics, they easily feel stressful. One of the main recommendations to overcome stressful conditions is to provide the science teachers ‘topic specific pedagogy’ during in-service training. 相似文献

How can universities ensure that strategic aims to integrate research and teaching through engaging students in research-based experiences be effectively realised within institutions? This paper reports on the findings of a qualitative study exploring academics’ perceptions of the challenges and barriers to implementing undergraduate research. Academics were asked about perceived constraints and enablements, how they defined undergraduate research, the forms of undergraduate research used, and they were encouraged to provide examples. Perceived constraints included particular institutional policies and structures, academics’ mindsets and lack of skills and questions of time and money. It was found that different definitions of undergraduate research lead to different practices and varying opportunities for further development. This paper presents different forms of engagement in undergraduate research allied to these different definitions and it draws on interviewees’ ideas about what has been enabling in their context to suggest possible strategies for institutions to move forward. 相似文献
