The combined effects of pH and temperature on red pigment production and fungal morphology were evaluated in a submerged culture
of Penicillium purpurogenum GH2, using Czapek-Dox media with d-xylose as a carbon source. An experimental design with a factorial fix was used: three pH values (5, 7, and 9) and two temperature
levels (24 and 34 °C) were evaluated. The highest production of red pigment (2.46 g/L) was reached with a pH value of 5 and
a temperature of 24 °C. Biomass and red pigment production were not directly associated. This study demonstrates that P. purpurogenum GH2 produces a pigment of potential interest to the food industry. It also shows the feasibility of producing and obtaining
natural water-soluble pigments for potential use in food industries. A strong combined effect (p<0.05) of pH and temperature was associated with maximal red pigment production (2.46 g/L). 相似文献

The ARCS Model of Motivational Design has been used myriad times to design motivational instructions that focus on attention, relevance, confidence and satisfaction in order to motivate students. The Instructional Materials Motivation Survey (IMMS) is a 36‐item situational measure of people's reactions to instructional materials in the light of the ARCS model. Although the IMMS has been used often, both as a pretest and a posttest tool serving as either a motivational needs assessment prior to instruction or a measure of people's reactions to instructional materials afterward, the IMMS so far has not been validated extensively, taking statistical and theoretical aspects of the survey into account. This paper describes such an extensive validation study, for which the IMMS was used in a self‐directed instructional setting aimed at working with technology (a cellular telephone). Results of structural equation modeling show that the IMMS can be reduced to 12 items. This Reduced Instructional Materials Motivation Survey IMMS (RIMMS) is preferred over the original IMMS. The parsimonious RIMMS measures the four constructs attention, relevance, confidence and satisfaction of the ARCS model well, and reflects its conditional nature. 相似文献

In which areas and domains do individual teacher educators prefer to work on their professional development? What kind of learning activities do they want to take on and with whom? Are there significant differences in these preferences between teacher educators? This article reports on a recent survey (N = 268) about the professional development of teacher educators and differences in learning preferences between less and more experienced teacher educators and between university-based and school-based teacher educators. Findings show, for example, that while most university-based teacher educators were mainly interested in improving their teaching, less experienced school-based teacher educators were more focussed on aspects such as coaching skills. In this study, ‘learning profiles’ have been developed for four categories of teacher educators. These profiles may help to create more meaningful arrangements for teacher educators’ initial education and further professional development in a context where teacher education is required to have a more school-based as well as a more research-based orientation. 相似文献

The University of Helsinki established a Teachers’ Academy to reward excellence in teaching. This study focuses on teachers’ significant networks and their meaningful conversations about teaching and learning before the establishment of the Teachers’ Academy. The research data consisted of answers to open-ended questions, and were examined using social network analysis. The teachers’ network consisted of significant relations with (1) colleagues and other teachers, (2) peers in pedagogical courses and pedagogical experts, (3) students, and (4) family members and friends. The conversations with different parties varied in nature, content and the level of confidentiality. 相似文献

Changes in the classification of autism and Asperger's syndrome led to changes in social perception of ASD. Since last criteria, studies indicate higher levels of stigma towards ASD than towards Asperger's. These prejudices are barriers to inclusive education. Thus, it is relevant (1) to evaluate pre-service teachers' self-efficacy towards the label of ASD; (2) to evaluate pre-service teachers' self-efficacy towards the label of Asperger's and (3) to compare those results to analyse whether the use of different diagnostic labels brings about different levels of self-efficacy. One hundred and eighty-six primary education pre-service teachers participated in the current study. Two adaptations of the Autism Self-Efficacy Scale for Teachers (ASSET) were used: a version with the label of ‘ASD’ (n = 96) and another for ‘Asperger's’ (n = 90). The scores obtained by the group asked about ASD were high according to the ASSET score range, while the scores obtained by the group asked about Asperger's were medium. After comparing the results, participants asked about the label ASD showed higher levels of self-efficacy than participants asked about Asperger's. These results could be a consequence of the consolidation of the ASD diagnosis among society and the higher presence of children with ASD in schools and cultural products, among other factors. 相似文献

The implementation of inclusive practices in mainstream education remains particularly difficult in the French context and is influenced by various factors including the types of disability labels, and the type of assessment practices that are used. Indeed, how student disability is labelled could impact teacher attitudes by notably disfavouring students labelled with autism. Moreover, normative assessment is strongly linked with selection at schools—a function that works against teacher attitudes towards inclusive education. This article reports on a study in which we examined teacher intentions to use materials accommodated to special educational needs students, as a function of special needs labelling. Specifically, this refers to the use of labels for either a disability or special educational need, in connection to tasks associated with learning or assessment. The results of our study revealed that, for both types of labels, the intentions to use accommodated materials are lower when teachers are asked to assess student competence than when prompted to teach this competence. These findings are discussed with consideration to the incompatibility between selection in schools—which is aligned with the principle of meritocracy—and efforts to promote inclusive education practices. 相似文献
