Inquiry and Astronomy: Preservice Teachers’ Investigations of Celestial Motion

This study investigated the impact of an open inquiry experience on elementary science methods students’ understanding of celestial motion as well as the methods developed by students to answer their own research questions. Pre/post interviews and assessments were used to measure change in participants’ understanding (N = 18). A qualitative approach was used to describe the nature of each participant’s investigation through an analysis of their science journal and poster presentations. A comparison of participants’ inquiry projects with the change in their understanding revealed that while most participants improved in both their area of inquiry and beyond, elementary science methods students may need more guidance to reach a full scientific understanding across all aspects of celestial motion.     

Writing week-journals to improve the writing quality of fourth-graders’ compositions

Students’ writing problems are a global educational concern and is in need of particular attention. This study aims to examine the impact of providing extra writing opportunities (i.e., writing journals) on the quality of writing compositions. A longitudinal cluster-randomized controlled design using a multilevel modeling analysis with 182 fourth grade students was conducted. We examined whether students’ writing quality differed when writing journals on a weekly basis for 12 weeks, compared with a control group. Three covariates were analyzed, namely: (i) the students’ attitudes towards writing; (ii) their self-efficacy in writing; (iii) and their use of self-regulation (SRL) strategies while writing. Findings have shown that students who wrote week-journals significantly improved the writing quality of their compositions and reported a higher use of SRL strategies in writing. Nevertheless, self-efficacy and attitude towards writing were found to not be related to the quality of the compositions. Moreover, data indicated that the writing quality of compositions improved along with the writing quality of the week-journals. Findings suggest the use of week-journals in class to promote writing.     

‘Learning Experience’ Provided by Science Teaching Practice in a Classroom and the Development of Students’ Competences

According to the literature, there is a very important corpus of knowledge that allows for the investigation of some dimensions of ‘learning experience’ provided to students, in relation to epistemic, pedagogical and meta-cognitive practices. However, in the literature, there is little investigation into the invariance (or not) of the characteristics of students’ learning experience while being taught a scientific subject by the same teacher. This paper suggests that the relationship between the learning experience provided and the competences developed is not properly highlighted. This paper analyses the learning experience provided to students in epistemic, pedagogical and meta-cognitive terms. The students were taught the proprieties and applications of light by one teacher, in three classes, over 7 weeks. We analysed the data in each referred learning experience, using a pre-defined category system. The students’ competences were evaluated by a competence test. The epistemic demand of each item and the students’ performances were also analysed. Our findings point to the non invariance of learning experiences provided to students and the influence of some dimensions of learning experiences provided in the development of certain competences. These findings and their implications are contextualized and discussed.     

‘The constant rejections hurt’: Skills and personal attributes needed to successfully complete a thesis by publication

The thesis by publication (TBP) is an increasingly popular approach to doctoral education that sees candidates publishing their research during their candidature, and including these outputs in their final thesis submission. Responsive to the realities of modern academia, a TBP provides doctoral candidates with opportunities to engage in the scholarly publication process, and to build their research portfolio. As the TBP gains further traction in many fields and countries, there is a need to better understand the skills and attributes needed to complete a TBP successfully. This paper draws on the views of 246 recent doctoral graduates of Australian universities to identify the skills and attributes they felt supported their success. Their responses have implications for the development and refinement of institutional policies and programs that are sensitive to the needs and experiences of doctoral candidates seeking to publish during candidature and create a TBP. As editors, peer‐reviewers, and publishers see a growing influx of papers sole‐ or co‐authored by doctoral candidates in response to the trend toward TBP, they may find themselves involved in supporting students to develop the skills and attributes needed to successfully publish during candidature.     

儒家环境伦理学：与自然共鸣

确实在儒家道德哲学中没有一个充分发展的环境伦理学系统,但儒家思想与当代环境伦理学争论的中心问题直接相关,而不是过去的乌托邦幻想或灵魂的残余。中国儒家传统道德在丰富我们对人与自然关系的理解上能够提供有价值的智力资源。儒家道德理想中有关人与自然和谐相处的思想,可以为我们选择一种新的解决环境问题的方法提供支持。     

A Behind‐the‐Scenes Guide to School‐Based Research

Schools are an important context for both basic and applied scientific research. Unlike the laboratory, however, the physical and social conditions of schools are not under the exclusive control of scientists. In this article, we liken collecting data in schools to putting on a theatrical production. We begin by describing the large cast of characters whose collaborative efforts make school‐based research possible. Next, we address the critics, including the university Institutional Review Board (IRB) and school administrators, whose feedback often improves the final study design. We then turn our attention to set building, stage directions, and rehearsals—key steps in the iterative process of refining study procedures. We end with a discussion of the day of data collection itself and activities that take place after the curtain drops. Throughout, we make recommendations based on our recent experience collecting data at several high schools.     

Influence of using challenging tasks in biology classrooms on students’ cognitive knowledge structure: an empirical video study

Empirical analysis of secondary biology classrooms revealed that, on average, 68% of teaching time in Germany revolved around processing tasks. Quality of instruction can thus be assessed by analyzing the quality of tasks used in classroom discourse. This quasi-experimental study analyzed how teachers used tasks in 38 videotaped biology lessons pertaining to the topic ‘blood and circulatory system’. Two fundamental characteristics used to analyze tasks include: (1) required cognitive level of processing (e.g. low level information processing: repetiition, summary, define, classify and high level information processing: interpret-analyze data, formulate hypothesis, etc.) and (2) complexity of task content (e.g. if tasks require use of factual, linking or concept level content). Additionally, students’ cognitive knowledge structure about the topic ‘blood and circulatory system’ was measured using student-drawn concept maps (N?=?970 students). Finally, linear multilevel models were created with high-level cognitive processing tasks and higher content complexity tasks as class-level predictors and students’ prior knowledge, students’ interest in biology, and students’ interest in biology activities as control covariates. Results showed a positive influence of high-level cognitive processing tasks (β?=?0.07; p?.01) on students’ cognitive knowledge structure. However, there was no observed effect of higher content complexity tasks on students’ cognitive knowledge structure. Presented findings encourage the use of high-level cognitive processing tasks in biology instruction.
