Dopamine Receptor D2 Polymorphism Moderates the Effect of Parental Education on Adolescents' School Performance

ABSTRACT— High parental socioeconomic status is known to have a positive effect on students' academic achievement. We examined whether variation in the dopamine receptor gene (DRD2 polymorphism, rs 1800497) modifies the association between parental educational level and school performance in adolescence. The participants were a randomly selected subsample of individuals participating in the Cardiovascular Risk in Young Finns study (921 girls and 742 boys) aged 12–15 years at the time school performance was assessed. The genotyping was performed using TaqMan 5'-nuclease assay. A significant interaction was found between childhood parental educational level and students' DRD2 polymorphism on academic achievement after adjustment for age, gender, household income, parental occupation, maternal nurturance, hyperactivity, and sociability. Parental educational level was significantly positively associated with school achievement in the A2/A2 ( n  = 1,061) and the A1/A2 ( n  = 529) genotype groups, but was negative and statistically insignificant in participants carrying the A1/A1 ( n  = 73) genotype. It is concluded that the extent to which parental education status affects an individual's academic achievement may be dependent on the individual's genetic constitution. The findings may increase an acceptance of genetic influence in education, and, consequently, may increase accurateness of educational interventions.     

The association between mathematical word problems and reading comprehension

This study aimed to investigate the interplay between mathematical word problem skills and reading comprehension. The participants were 225 children aged 9–10 (Grade 4). The children’s text comprehension and mathematical word problem‐solving performance was tested. Technical reading skills were investigated in order to categorise participants as good or poor readers. The results showed that performance on maths word problems was strongly related to performance in reading comprehension. Fluent technical reading abilities increased the aforementioned skills. However, even after controlling for the level of technical reading involved, performance in maths word problems was still related to reading comprehension, suggesting that both of these skills require overall reasoning abilities. There were no gender differences in maths word problem‐solving performance, but the girls were better in technical reading and in reading comprehension. Parental levels of education positively predicted children’s maths word problem‐solving performance and reading comprehension skills.     

Pre-service teachers’ experiences of scaffolded learning in science through a computer supported collaborative inquiry

Scaffolding helps the novice to accomplish a task goal or solve a problem that otherwise would be beyond unassisted efforts. Scaffolding firstly aims to support the learner in accomplishing the task and secondly in learning from the task and improving future performance. This study has examined pre-service teachers’ experiences of technologyenhanced/computer-supported collaborative inquiry learning when studying the anatomy of fish. The study investigated pre-service teachers’ experiences of scaffolded use of a Wiki in structuring a dissection inquiry activity combined with scaffolded use of digital imaging to support problematizing during the sense making process. Quantitative data on the benefits experienced by the pre-service teachers in using the Wiki and in digital imaging were collected through responses to questions posted through an online questionnaire. Structure equation modeling was used to investigate the relationship between scaffolding with the Wiki and the experienced benefits of using technology. The use of structural scaffolding with the Wiki was not seen to be directly related to the experienced benefits. In encouraging knowledge acquisition and supporting deeper thinking on the topic, digital imaging had the strongest positive relationship to the experienced benefits of the technology, but there was no direct relationship with the use of the Wiki. However, scaffolding by structuring the activity with the Wiki had meditational, indirect, effects through visualizations and peer support to intentional and active participation and thus the scaffolds were working during the inquiry synergistically. For teacher education this means that pre-service teachers may recognize the benefits of using technology only through a significant experience and thus under value the role of the technology itself.

Designing a user‐friendly microcomputer‐based laboratory package through the factor analysis of teacher evaluations

In this study we analyse how the experiences of chemistry teachers on the use of a Microcomputer‐Based Laboratory (MBL), gathered by a Likert‐scale instrument, can be utilized to develop the new package Empirica 2000. We used exploratory factor analysis to identify the essential features in a large set of questionnaire data to see how our previous MBL package, Empirica for Windows 4.0, looks from the point of view of experienced chemistry teachers. Together, a six‐factor solution explained 50.1% of the common variance and indicated the teachers' perspective on the use of a MBL package in chemical education. The factors were: ‘Versatility of the tool’, ‘User interface’, ‘Data presentation’, ‘Data acquisition’, ‘Set up’, and ‘Usability’. Based on the data, some conclusions concerning the software development and desired new features in the prototype software are discussed in the framework of each factor.     

TEACHER’S REFLECTION OF INQUIRY TEACHING IN FINLAND BEFORE AND DURING AN IN-SERVICE PROGRAM: EXAMINATION BY A PROGRESS MODEL OF COLLABORATIVE REFLECTION

In inquiry-based science education, there have been gradual shifts in research interests: the nature of scientific method, the debates on the effects of inquiry learning, and, recently, inquiry teaching. However, many in-service programs for inquiry teaching have reported inconsistent results due to the static view of classroom inquiries and due to the partial perspective between individual and collaborative reflections. Thus, by means of a theoretical progress model of collaborative reflection, this qualitative research aims to investigate reflections of four participant teachers before and during a half-year in-service teacher program. The model captures the following four interactions for each individual teacher and among the teacher cohort: belief to practice, practice to belief, stimulation, and reinforcement. The audio–video data and their quantification allowed identification of the teachers’ consistent prior beliefs and practices as a multiplicity of inquiry teaching and their interwoven progress during the program. The findings are further discussed in terms of the implicit development and the richer repertoire.     

Supporting collaborative inquiry during a biology field trip with mobile peer-to-peer tools for learning: a case study with K-12 learners

This study explores how collaborative inquiry learning can be supported with multiple scaffolding agents in a real-life field trip context. In practice, a mobile peer-to-peer messaging tool provided meta-cognitive and procedural support, while tutors and a nature guide provided more dynamic scaffolding in order to support argumentative discussions between groups of students during the co-creation of knowledge claims. The aim of the analysis was to identify and compare top- and low-performing dyads/triads in order to reveal the differences regarding their co-construction of arguments while creating knowledge claims. Although the results revealed several shortcomings in the types of argumentation, it could be established that differences between the top performers and low performers were statistically significant in terms of social modes of argumentation, the use of warrants in the mobile tool and in overall participation. In general, the use of the mobile tool likely promoted important interaction during inquiry learning, but led to superficial epistemological quality in the knowledge claim messages.

Questions asked by primary student teachers about observations of a science demonstration

Teacher questioning has a central role in guiding pupils to learn to make scientific observations and inferences. We asked 110 primary student teachers to write down what kind of questions they would ask their pupils about a demonstration. Almost half of the student teachers posed questions that were either inappropriate or presupposed that the pupils would know the answer. For example, they directly asked for an explanation of the phenomenon instead of asking what inferences the pupils could make on the basis of their observations. There was a lack of questions that would draw the pupils’ attention to the variables that may cause the phenomenon to happen. Only about 15% of the student teachers formed questions such as ‘What is happening?’ or ‘How is it happening?’. All in all, primary student teachers seem to need extra practice in forming questions based on scientific observation.
