Content Knowledge for Teaching: What Makes It Special?

Pedagosko i psiholosko testiranje i procjenjivanje spadaju među najvažnije doprinose znanosti o ponasanju nasem drustvu i pružaju temeljna i znacajna poboljsanja u odnosu na ranije postupke. Iako se ne može ustvrditi da su svi testovi dovoljno usavrseni niti da su sva testiranja razborita i korisna, postoji velika kolicina informacija koje ukazuju na ucinkovitost kvalitetnih instrumenata u onim situacijama u kojima je njihovo koristenje potkrijepljeno validacijskim podacima. Pravilna upotreba testova može dovesti do boljih odluka o pojedincima i programima nego sto bi to bio slucaj bez njihovog koristenja, a također i ukazati na put za siri i pravedniji pristup obrazovanju i zaposljavanju. Međutim, losa upotreba testova može dovesti do zamjetne stete nanesene ispitanicima i drugim sudionicima u procesu donosenja odluka na temelju testovnih podataka. Cilj Standarda je promoviranje kvalitetne i eticne upotrebe testova te uspostavljanje osnovice za ocjenu kvalitete postupaka testiranja. Svrha objavljivanja Standarda je uspostavljanje kriterija za evaluaciju testova, provedbe testiranja i posljedica upotrebe testova. Iako bi evaluacija prikladnosti testa ili njegove primjene trebala ovisiti prvenstveno o strucnim misljenjima, Standardi pružaju okvir koji osigurava obuhvacanje svih relevantnih pitanja. Bilo bi poželjno da svi autori, sponzori, nakladnici i korisnici profesionalnih testova usvoje Standarde te da poticu druge da ih također prihvate.

Standards for educational and psychological testing

The author suggests that we apply recent research knowledge to improve our conceptualization, measures, and methodology for studying the effects of teachers’ professional development on teachers and students. She makes the case that there is a research consensus to support the use of a set of core features and a common conceptual framework in professional development impact studies. She urges us to move away from automatic biases either for or against observation, interviews, or surveys in such studies. She argues that the use of a common conceptual framework would elevate the quality of professional development studies and subsequently the general understanding of how best to shape and implement teacher learning opportunities for the maximum benefit of both teachers and students.

Improving Impact Studies of Teachers’ Professional Development: Toward Better Conceptualizations and Measures

The development of adequate student conceptions of the nature of science has been a perennial objective of science instruction regardless of the currently advocated pedagogical or curricular emphases. Consequently, it has been an area of prolific research characterized by several parallel, but distinct, lines of investigation. Although research related to students' and teachers' conceptions of the nature of science has been conducted for approximately 40 years, a comprehensive review of the empirical literature (both quantitative and qualitative) has yet to be presented. The overall purpose of this review is to help clarify what has been learned and to elucidate the basic assumptions and logic which have guided earlier research efforts. Ultimately, recommendations related to both methodology and the focus of future research are offered.

Students' and teachers' conceptions of the nature of science: A review of the research

This paper aimed to review, and assess the 'effectiveness' of the attempts undertaken to improve prospective and practising science teachers' conceptions of nature of science (NOS). The reviewed attempts could be categorized into two general approches: implicit and explicit. Implicit attempts utilized science process-skills instruction or engagement in science-based inquiry activities to improve science teachers' conceptions of NOS. To achieve the same goal, explicit attempts used instruction geared towards various aspects of NOS and/or instruction that utilized elements from history and philosophy of science. To the extent that teachers' NOS conceptions were faithfully assessed by the instruments used in the reviewed studies, the explicit approach was relatively more effective in enhancing teachers' views. The relative ineffectiveness of the implicit approach could be attributed to two inherent assumptions. The first is that developing an understanding of NOS is an 'affective', as compared to a 'cognitiv...

Improving Science Teachers' Conceptions of Nature of Science: A Critical Review of the Literature.

The purpose of this study was to delineate the factors that mediate the translation of preservice teachers' conceptions of the nature of science (NOS) into instructional planning and classroom practice. Fourteen preservice secondary science teachers participated in the study. Prior to their student teaching, participants responded to an open-ended questionnaire designed to assess their conceptions of the NOS. Analysis of the questionnaires was postponed until after the completion of student teaching to avoid biasing the collection and/or analysis of other data sources. Throughout student teaching, participants' daily lesson plans, classroom videotapes, and portfolios, and supervisors' weekly clinical observation notes were collated. These data were searched for explicit references to the NOS. Following student teaching, participants were individually interviewed to validate their responses to the open-ended questionnaire and to identify the factors or constraints that mediate the translation of their conceptions of the NOS into their classroom teaching. Participants were found to possess adequate understandings of several important aspects of the NOS including the empirical and tentative nature of science, the distinction between observation and inference, and the role of subjectivity and creativity in science. Many claimed to have taught the NOS through science-based activities. However, data analyses revealed that explicit references to the NOS were rare in their planning and instruction. Participants articulated several factors for this lack of attention to the NOS. These included viewing the NOS as less significant than other instructional outcomes, preoccupation with classroom management and routine chores, discomfort with their own understandings of the NOS, the lack of resources and experience for teaching the NOS, cooperating teachers' imposed restraints, and the lack of planning time. In addition to these volunteered constraints, the data revealed others related to an intricate interaction between participants' perspectives on the NOS, pedagogy, and instructional outcomes. © 1998 John Wiley & Sons, Inc.

The nature of science and instructional practice: Making the unnatural natural

The construct “nature of science” (NOS) has been advocated as an important goal
for students studying science for approximately 100 years (Central Association of
Science and Mathematics Teachers, 1907). Most recently, NOS has been advocated
as a critical educational outcome by various science education reform documents
worldwide (e.g., Australia, Canada, South Africa, United Kingdom, United States).
To be blunt, when it comes to NOS, one is hard pressed to find rhetoric arguing
against its importance as a prized educational outcome. Still, detractors do exist
(Winchester, 1993). The observation that NOS has been a perennial goal of science
education, and is now receiving increased emphasis, can be construed to mean that
high school graduates, and the general citizenry, do not possess (and never have
possessed) adequate views of NOS. The research reviewed later in this chapter provides clear support for such a notion. That said, has anything been lost? Is it really
important for students and the general citizenry to understand NOS? What have
we not accomplished because our students do not have good understandings of
NOS? What can we make of the obsession with NOS?

Nature of Science: Past, Present, and Future

Reform efforts emphasize teaching science to promote contemporary views of the nature of science (NOS) and scientific inquiry. Within the framework of situated cognition, the assertion is that engagement in inquiry activities similar to those of sci- entists provides a learning context conducive to developing knowledge about the meth- ods and activities through which science progresses, and, in turn, to developing desired views of NOS. The inclusion of a scientific inquiry context to teach about NOS has in- tuitive appeal. Yet, whether the learners are students, teachers, or scientists, the empirical research does not generally support the claim that engaging in scientific inquiry alone enhances conceptions of NOS. We studied developments in NOS conceptions during a
