The development of science process skills in authentic contexts

Instructional strategies and curriculum sequences aimed at teaching process skills have received considerable attention in science education. On the other hand, the teaching of domain-independent, context-free skills has been subject to criticism on the ground that important aspects of cognitive activities are functions of meaningful contexts. The intent of this study was to examine the development of integrated process skills in the context of open-inquiry laboratory sessions. The data-collection approach was qualitative and included videotapes of laboratory sessions, laboratory reports of students, and the reflective journals kept by the two teachers involved in the study. Forty-eight students from the Grade 11 introductory physics course, 29 students from the Grade 12 physics course, and 60 students from the Grade 8 general science course from an all-boys private school participated in the study. An interpretive research methodology was adopted for construction of meaning from the data. Students worked in collaborative groups during all of the open-inquiry laboratory sessions. Findings from the study indicate that students develop higher-order process skills through nontraditional laboratory experiences that provided the students with freedom to perform experiments of personal relevance in authentic contexts. Students learned to (a) identify and define pertinent variables, (b) interpret, transform, and analyze data, (c) plan and design an experiment, and (d) formulate hypotheses. Findings of this study suggest that process skills need not be taught separately. Integrated process skills develop gradually and reach a high level of sophistication when experiments are performed in meaningful context.     

Higher education marketing – does inducing anxiety facilitate critical thinking or more consumerism?

Consumerism acts to maintain the emotional reversal of work and family. Exposed to a continual bombardment of advertisements through a daily average of three hours of television (half of all their leisure time), workers are persuaded to ‘need’ more things. To buy what they now need, they need money. To earn money, they work longer hours. Being away from home so many hours, they make up for their absence at home with gifts that cost money. They materialize love. And so the cycle continues [Baumann, Z. (2007). Collateral casualties of consumerism. Journal of Consumer Culture, 7, 1].     

Should contentment be a key aim in higher education?

Higher education institutions are major concentrations of political, social, economic, intellectual and communicative resources. They reach freely across populations and cultures and connect to government, professions, industry and the arts. The neoliberal logic of markets has entered the realm of (higher) education. This leads to discourse on the benefits of education being positioned almost exclusively in terms of their effect on income. The perspective taken in the paper is the development of a happiness motive that asks education to challenge what it is to be a member of society: What moral and ontological stance one will seek to take in developing one’s future? The satisfied student perpetuates the current lifeworld in which they find themselves, seeking to improve the quality of the services provided. It is proposed that an overly emphasised desire satisfaction culture inhibits the edifying mission of universities. This is not to argue against high-quality service provision but to differentiate it from the edifying role of personal challenge, determination and social responsibility, conceptualised here as profound happiness or contentment, and the university’s role in its development. It calls for a different and more refreshing approach to higher education.     

Students' Learning of a Generalized Theory of Sound Transmission from a Teaching–Learning Sequence about Sound,Hearing and Health

Learning abstract concepts such as sound often involves an ontological shift because to conceptualize sound transmission as a process of motion demands abandoning sound transmission as a transfer of matter. Thus, for students to be able to grasp and use a generalized model of sound transmission poses great challenges for them. This study involved 199 students aged 10–14. Their views about sound transmission were investigated before and after teaching by comparing their written answers about sound transfer in different media. The teaching was built on a research-based teaching–learning sequence (TLS), which was developed within a framework of design research. The analysis involved interpreting students' underlying theories of sound transmission, including the different conceptual categories that were found in their answers. The results indicated a shift in students' understandings from the use of a theory of matter before the intervention to embracing a theory of process afterwards. The described pattern was found in all groups of students irrespective of age. Thus, teaching about sound and sound transmission is fruitful already at the ages of 10–11. However, the older the students, the more advanced is their understanding of the process of motion. In conclusion, the use of a TLS about sound, hearing and auditory health promotes students' conceptualization of sound transmission as a process in all grades. The results also imply some crucial points in teaching and learning about the scientific content of sound.
