Who Needs What: Recommendations for Designing Effective Online Professional Development for Computer Science Teachers

The new Advanced Placement (AP) Computer Science (CS) Principles course increases the need for quality CS teachers and thus the need for professional development (PD). This article presents the results of a 2-year study investigating how teachers teaching the AP CS Principles course for the first time used online PD material. Our results showed that the teaching and computing background of teachers had a significant impact on the teachers' need for and use of online PD material. More specifically, novice CS teachers needed and used PD for developing their pedagogical content knowledge (PCK). Non-CS teachers needed and used PD materials emphasizing content knowledge. Experienced CS teachers believed they had little need for PD even though they were teaching a new course. Our study makes three recommendations for designing effective online PD for CS teachers: match PD to teachers' background, align PD with the course curriculum, and use effective motivational design to enhance teacher engagement.

The Relationship Between Objectified Body Consciousness and Wellness in a Group of College Women

Objectified body consciousness theory provides a framework for understanding young women's negative body experiences and their impact on well‐being. This study examined the impact of body surveillance, body shame, and appearance control beliefs, the 3 components of objectified body consciousness, on wellness in college women. Data indicated a negative relationship between body surveillance and body shame and several components of wellness and a positive relationship between appearance control beliefs and aspects of wellness. Implications are examined.     

A participatory approach to the evaluation of participatory museum research projects

ABSTRACT

In this paper, we will describe, justify and critique a participatory approach that we have developed in order to evaluate the success of a participatory research project that was exploring ways of making museum learning experiences more inclusive for adults who have a diverse range of access preferences. Because we were researching in a unique space at the intersection of inclusive museum education, inclusive technologies and participatory research, we have needed to develop an original evaluation approach, informed by methods and frameworks derived from other fields. We present examples of the kind of evaluation information that the framework elicited and use this as a basis to critique the strengths and weaknesses of the framework. Our experience of using creative methods for eliciting evaluation data suggest that useful information about participation can be revealed but that further improvements can be made in order to make the research experience more participatory.     

Understanding number sequences leads to understanding mathematics concepts

Ninety-six first grade students in an urban school system were tested in October and May on reading, mathematics, and their understanding of sequences of letters and numbers. A time lag analysis was subsequently conducted. In such analyses, cross-correlations between the first measurement of one variable and the second measurement of another are compared. The larger of the correlations indicates the direction of the relationship; i.e., which variable is most likely to be causal. Correlations of the fall scores on the number sequences with spring scores on the mathematics concepts scale were significant, while correlations of the fall mathematics concepts scores with spring number sequence scores were negligible. This indicates that understanding such complex sequences has a directional effect on understanding mathematics concepts. Fall–spring cross-correlations for the letter sequences and reading test, although significant, did not differ, and hence provided no indication of the direction of the relationship. Potential explanations were discussed.     

Online Physics Lab Exercises—a Binational Study on the Transfer of Teaching Resources

In this paper, we present the design and the results of a comparative study that evaluated the success of a transfer of an online-teaching resource between two universities, one in Germany and one in the USA. The teaching resource is an online physics lab that has been used in the physics education of medical students in Germany since 2003. The online lab covers geometrical optics and the optics of the human eye using interactive screen experiments. It was translated and transferred to a university in the USA where it was used and evaluated with a group of pre-health students. In a cross-national study, students’ backgrounds (demographic data, selected cognitive abilities, previous knowledge, and self-concept in physics), students’ attitudes towards the online lab, and their learning gain were compared. The results show significant differences between the German and the US cohorts with regard to students’ backgrounds. Despite these differences, the outcomes are similar, with slightly higher leaning gains for the US students. Students’ attitudes towards the online lab are similar in both countries but tend to be more positive among the US students. The results indicate that the transfer of the online lab to another educational system was successful.     

Experiences of the Relation between Teaching and Research: What do academics value?

Many attempts have been made to account for the relation between teaching and research. In general, studies have assumed the nature of this relation and characterised it as one that exists between externally defined indicators such as teaching effectiveness and research productivity . Most frequently used indicators are quantitative measures such as students' evaluations of teaching and publication counts. In contrast, few studies have explored how academics experience teaching and research and their inter-relation. The results of this small, qualitative study, consisting of interviews with a sample of academic staff who expressed strong views of the teaching/research relationship, show that there is substantial variation in academics' experiences of the meaning of this relation. The results suggest that such variation requires further exploration using methods that differ from those that have been associated with past research in this area.     

Linking Science and Statistics: Curriculum Expectations in Three Countries

This paper focuses on the curriculum links between statistics and science that teachers need to understand and apply in order to be effective teachers of the two fields of study. Meaningful statistics does not exist without context and science is the context for this paper. Although curriculum documents differ from country to country, this paper uses extracts from three countries: Australia, New Zealand and the USA. The statistical ideas from the Australian Curriculum: Mathematics, the New Zealand Mathematics and Statistics Curriculum and the US Common Core State Standards for Mathematics are linked to the relevant parts of the Australian Curriculum: Science, the New Zealand Science Curriculum and the US Next Generation Science Standards for States, by States. Teachers of mathematics need to be aware of the potential of science to provide meaningful contexts within which to set statistical investigations. Similarly, teachers of science, who are developing methods for implementing investigations and experiments in their classrooms, need to be aware of the close ties to statistical tools for decision-making.     

Standards and assessment: coherence from the teacher’s perspective

We sought to understand how teachers’ perspectives on standards-based instructional practices, classroom assessment, and external testing do or do not show coherence and alignment. Based on survey methods (n?=?155) and interviews with a sample of secondary school teachers (n?=?9) in a large urban district in the USA, we explored general trends and individual teachers’ viewpoints. Our results suggest that the teachers’ instructional use of standards, classroom assessment preferences, and beliefs about the test-driven system are moderately correlated. Interview data provide insight into reasons teachers hold beliefs that do or do not fit well into a coherent assessment system.     

Out of the toolbox: toddlers differentiate wobbly and wooden handrails

This study examined whether 16-month-old walking infants take the material composition of a handrail into account when assessing its effectiveness as a tool to augment balance. Infants were encouraged to cross from one platform to another via bridges of various widths (10, 20, 40 cm) with either a "wobbly" (foam or latex) or a wooden handrail available for assistance. Infants attempted to walk over wider bridges more often than narrow ones, and attempts were more frequent when the sturdy wooden handrail was available. Infants tailored their exploratory behaviors, bridge-crossing strategies, and handrail-use strategies to the material properties of the rail.
