A validity study of two paper-pencil tests of concrete and formal operations

Two group paper-pencil batteries, the Longeot (consisting of three subtests) and three puzzles (KLR) from Science Teaching and the Development of Reasoning, were administered to 607 students from ninth and tenth grade mathematics and science classes. A subsample of 69 students was then administered three Inhelder tasks (chemicals, rods, and shadows). In general, the expected developmental trends were confirmed, with formal status being most difficult to attain on the Inhelder tasks and easiest to attain on the Longeot. The correlations between the KLR and Inhelder (0.61, p < 0.01) and the Longeot and Inhelder (0.55, p < 0.05) were moderately high. According to the method of Shayer (Note 2), it was found that each of five paper-pencil subtests discriminates at or between the 2B (late concrete) and 3A (early formal) levels while the sixth subtest, the mealworm puzzle, was found to discriminate at the 3A level. This study indicates that either group battery may be useful in identifying transitional subjects. However, if a more stringent criterion of “formal” is needed, a “success” rate of four or five out of the six subtests may be required. Both group batteries are relatively easy to administer and score with a minimum of guidance, although the KLR scoring might need to be simplified for use by the practitioner. Sex differences found on the KLR and the Longeot are suggestive of the potential differential use of these tests by researchers investigating sex differences in achievement or aptitude.     

Determinants of sales and price at auction for three Australian Indigenous artists: to pool or not to pool?

Albert Namatjira (1902–1959), Emily Kame Kngwarreye (c1910–1996) and Rover (Julama) Thomas (c1926–1998) are three of Australia’s best-known Indigenous artists. Each is known for one style of painting—Namatjira for watercolor on paper, Kngwarreye for acrylic (synthetic polymer) on canvas and Thomas for natural earth pigments on canvas. We estimate a sample selectivity model using data from the Australian Art Sales Digest to study the determinants of sales and the hammer price of artworks offered at auction from these artists. The results show that pre-sale information on the artwork and auction effects are significant and that the three artists studied are very different from each other. Thus, data should not be pooled when estimating these models.     

Video game discourses and implications for game-based education

Increasingly prevalent educational discourses promote the use of video games in schools and universities. At the same time, populist discourses persist, particularly in print media, which condemn video games because of putative negative effects on behaviour and socialisation. These contested discourses, we suggest, influence the acceptability of games and limit critical analysis of their effectiveness as pedagogic tools. This article focuses on the representation of video games in media discourse. We present insights from a small-scale study of the construction of video game discourses in the UK print media in 2013, and discuss three areas that emerged. First, the assumptions inherent in the representation of the ‘video game’; second, the implied lack of agency in the behaviour of ‘the gamer’; and third, the way in which blame is manipulated. Finally, we consider the implications for game-based education.     

Examining the Relationship Between Technological Pedagogical Content Knowledge (TPACK) and Student Achievement Utilizing the Florida Value-Added Model

Utilizing a correlational research design, we sought to examine the relationship between the technological pedagogical content knowledge (TPACK) of in-service teachers and student achievement measured with each individual teacher's Value-Added Model (VAM) score. The TPACK survey results and a teacher's VAM score were also examined, separately, with respect to teacher attributes. Upon examination of VAM scores and teacher attributes, the subject area, the percentage of economically disadvantaged students at the teacher's school, and the grade level of the teacher were all significantly related to VAM scores. In addition, the TPACK survey results overall and its constructs were examined with teacher attributes. The significant relationships were gender, subject area, the number of certifications, highest degree held by the teacher, years teaching, and teaching in/out of area. The analysis showed no significant relationship between a teacher's VAM score and the TPACK survey overall or its individual constructs.     

From discrete intervention to engage marginalised students to whole-school initiative to engage all students

An enduring educational dilemma is that young people from economically disadvantaged backgrounds do not have their needs met in conventional schooling. As a result, many have left school by Year 11. To counter this trend, some schools in disadvantaged areas introduce targeted in-school interventions before Year 11 to meet the needs of their students. Many of these interventions, which are highly successful in engaging students and supporting them to achieve, have insights to offer schools, but they remain on the margins as programmes for particular young people. However, a government secondary school in Victoria, Australia has been an exception. It was inspired to apply aspects of a successful intervention, Hands On Learning, to a whole-school initiative to enhance the engagement of all of its students. I used a case-study approach to investigate the initiative’s first year of implementation. Findings revealed that the majority of students did report engagement. However, economically disadvantaged students faced barriers to full participation that negatively impacted their learning experiences. The inequitable distribution of educational benefits demonstrated that whole-school adaptation of an intervention is not straightforward and unless the needs of disadvantaged students are targeted in the whole-school initiative, they are likely to experience educational disadvantage.
