Penelitian ini bertujuan menganalisis kebutuhan petunjuk praktikum berbasis Keterampilan Proses Sains (KPS) untuk mencapai kemampuan merancang eksperimen pada materi kalor reaksi kalorimetri. Penelitian dilakukan terhadap peserta didik kelas XI SMA Negeri 2 Kota Tanjungpinang. Variabel penelitian mencakup analisis kebutuhan bahan ajar dan analisis kesesuaian Kompetensi Inti (KI) dan Kompetensi Dasar (KD). Jenis penelitian yang dilakukan adalah penelitian deskriptif kualitatif. Tahapan pertama dalam penelitian ini adalah menganalisis kebutuhan bahan ajar dengan cara membandingkan dua petunjuk praktikum yang selama ini telah digunakan di sekolah tersebut, ditinjau dari aspek struktur format penulisan, aspek kreativitas, dan aspek keterampilan proses sains yang terdapat dalam petunjuk praktikum. Sehingga didapatkan kesimpulan bahwa petunjuk praktikum yang selama ini digunakan tidak memberikan kesempatan kepada peserta didiknya untuk merancang eksperimen yang telah ditentukan. Tahapan kedua yaitu menganalisis kesesuaian kompetensi inti dan kompetensi dasar, yang bertujuan untuk menentukan indikator pencapaian kompetensi (IPK) yang akan menjadi acuan dalam mengembangkan petunjuk praktikum berbasis keterampilan proses sains. Dari kedua tahapan yang telah dilakukan maka dapat disimpulkan bahwa peserta didik memerlukan petunjuk praktikum yang mampu mengonstruksi pikiran dan mengaktifkan kinerja mereka, sehingga pendekatan Keterampilan Proses Sains menjadi pilihan dalam mengembangkan petunjuk praktikum yang sesuai dengan karakteristik kurikulum 2013.   This research aims to analyze the needs of Science Process Skills based Practical Instruction to achieve the ability to design experiments on the calor of reaction. This research was done to the students of class XI SMA Negeri 2 Tanjungpinang City. Research Variable includes the analysis of the needs of the learning materials and analysis of the suitability of the Core Competence (KI) and Basic Competence (KD). The type of research conducted is descriptive qualitative research. The first stages in this research is to analyze the needs of learning materials by comparing two practical instructions that had been implementing in the school, from the aspects of the structure of writing format, creativity, and science process skills embedded in practical instructions. The conclusion of this research that current practical instructions does not give an opportunity to the participants to design determined experiments. The second stage, namely analyzing the suitability of core competence and basic competence, which aims to determine the indicators of achievement of the competencies (GPA) which will be a reference in developing process skills-based teaching instructions science. Of the two stages that has been done then it can be concluded that learners need practical instructions to construct  thinking and and their performance, so the Science Process Skills approach is an option in developing practical instruction suitable for the characteristics of the curriculum of 2013.

In an attempt to bridge the gap between architectural/interior design practice and education, ‘atmosphere’ as a prolific contemporary architectural debate in practice and theory is covered by the experiment of ‘Staging Poe’ carried out as a first year Design Studio through the study of Edgar Allen Poe’s selected poems. Poe’s 1846 text of ‘The Philosophy of Composition’, unfolding his analytical method of writing and emphasis on “effect” in poetry, provides a ground for experimenting with facets of materiality and structuring the studio. Aiming to cultivate intuitive design experiments of students into informed processes in hybridizing conceptual/textual and material/sensual aspects, studio is structured in two phases. In the first phase, “materialization”, idiosyncratic interpretations of students from words to materials with a focus on tectonic experiments and haptic experiences are sought in between materializing and dematerializing processes. In the second phase, the “atmospheric”, emphasis on dematerialization of the perception of materials through tools, such as light, color and sound is exercised to transform the object into a performance stage. Outcomes of the studio on aspects pertaining to material and materialities in creation of the immaterial that is the atmosphere is followed and evaluated through responses of students’ weekly reports.

Design Experiments

Reflection is an important aspect of learning in groups. In collective moments of reflection, learners can share and compare their ideas with others, and by doing so can reach an articulated and personal understanding of a learning task and domain. In the research presented here, e-mail is examined as a means for reflection in the context of group learning. In two design experiments, an e-mail tool is developed that seeks to (1) support collective reflection, and (2) overcome practical problems related to e-mail use in primary classrooms. Two prototypes of the tool are presented and tested in five primary classrooms. We conclude that e-mail supports collective reflection on a learning task after adding the following supportive measures to the regular e-mail program: (1) a fixed partnership, (2) fixed timing, (3) an exercise of individual freewriting, and (4) collective use of a paper worksheet.

Technological process of microwave-assisted leaching of vanadium with sulfate solution has been defined on the base of phase and chemical constituents of stone coal. The influence factors such as content of sulfuric acid, microwave power, and leaching time were studied on leaching rate of vanadium from the stone coal. One element experiments and orthogonal design experiments are carried out to achieve optimized parameters. The experimental results showed that the leaching rate of vanadium was improved by the change of influence factors at some range. The single leaching rate of vanadium reached 80.9% under the optimal conditions of sulfuric acid content of 12%, microwave power 539w,leaching time of 2h.

Undergraduate students may be attracted to science and retained in science by engaging in laboratory research. Experience as an apprentice in a scientist's laboratory can be effective in this regard, but the pool of willing scientists is sometimes limited and sustained contact between students and faculty is sometimes minimal. We report outcomes from two different models of a summer neuroscience research program: an Apprenticeship Model (AM) in which individual students joined established research laboratories, and a Collaborative Learning Model (CLM) in which teams of students worked through a guided curriculum and then conducted independent experimentation. Assessed outcomes included attitudes toward science, attitudes toward neuroscience, confidence with neuroscience concepts, and confidence with science skills, measured via pre-, mid-, and postprogram surveys. Both models elevated attitudes toward neuroscience, confidence with neuroscience concepts, and confidence with science skills, but neither model altered attitudes toward science. Consistent with the CLM design emphasizing independent experimentation, only CLM participants reported elevated ability to design experiments. The present data comprise the first of five yearly analyses on this cohort of participants; long-term follow-up will determine whether the two program models are equally effective routes to research or other science-related careers for novice undergraduate neuroscientists.

BACKGROUND Physician burnout was first identified in 1974, and it has been particularly prevalent during the first year of the pandemic. OBJECTIVE To objectively analyze the literature over the last five years for empirical evidence of burnout incident to the EHR and to identify barriers, facilitators, associated patient satisfaction to using the EHR to improve symptoms of burnout. METHODS No human subjects were used in this review, however 100% of participants in studies analyzed were adult physicians. Four research databases and one targeted journal were queried for studies commensurate with the objective statement from January 1, 2016 through January 31st 2021 (n=25). RESULTS The hours spent in documentation and workflow are responsible for the sense of loss of autonomy, lack of work-life balance, lack of control of one’s schedule, cognitive fatigue, a general loss of autonomy and poor relationships with colleagues. Researchers have identified training, local customization of templates and workflow, and the use of scribes to alleviate the administrative burden of the EHR and decreased symptoms of burnout. CONCLUSIONS The solutions provided in the literature only addressed two of the three factors, workflow and documentation time, but not the third, usability. Practitioners and administrators should focus on the former two factors because they are within their sphere of control. EHR vendors should focus on empirical evidence to identify usability features with the greatest impact to improve. Researchers should design experiments to explore solutions that address all three factors of the EHR that contribute to burnout. INTERNATIONAL REGISTERED REPORT RR2-10.2196/15490

Este texto apresenta um recorte de uma pesquisa que objetiva desenvolver, aplicar e analisar uma sequência de atividades caracterizada como ecologia de aprendizagem orientada para o Ensino e Aprendizagem de Probabilidade nos anos finais do Ensino Fundamental. Para isto foram selecionados estudantes dos 7o e 8o anos do Ensino Fundamental de uma escola pública no estado de Pernambuco. Baseado na teoria do Design Experiments, a pesquisa foi realizada por meio de três ciclos investigativos envolvendo respectivamente os conceitos de aleatoriedade, espaço amostral e quantificação e comparação de probabilidades. No desenvolvimento do design, percebemos que as principais dificuldades apresentadas pelos estudantes estão centradas no mapeamento das possibilidades, o que se deve à falta de repertório de estratégias utilizadas para combinações, ou porque os estudantes não as conhecem, ou porque não sabiam aplicá-las nas atividades. Os resultados apontam que os recursos e atividades vivenciados junto aos estudantes possibilitaram a aprendizagem do conhecimento probabilístico deste grupo. Dentre os resultados, afirmamos a construção conceitual das noções de probabilidade perpassando pela compreensão das diferentes situações de natureza aleatória e por situações envolvendo as concepções frequentista e clássica de probabilidade.
