Text editing in chemistry instruction

In two experiments, differential performance onchemistry problems was obtained for twotraining strategies: text editing andconventional problem solving. Text editingrequires students to scan the text of problemstatements and specify whether it providessufficient, missing or irrelevant informationfor solution. It was hypothesized that textediting, which emphasizes gaining familiaritywith schematic knowledge, would lead to higherachievement than conventional problem solving.Experiment one indicated that text editing wassuperior to conventional problem solving inlearning to solve molarity and dilutionproblems. In particular, students who weretrained in text editing skipped someintermediate steps while solving molarityproblems. In contrast, using stoichiometryproblems, experiment two showed that students whowere trained in text editing performed worsethan students given conventional problems tosolve. An error analysis suggested that becauseof its failure to direct students' attention tothe coherent problem structure in the firstinstance, text editing has no advantage overconventional problem solving in the domain ofstoichiometry problems. It was concluded thatthe suitability of a text editing trainingstrategy depends on the learning materials.     

A study of Korean middle school students’ interests in biology and their implications for biology education

This study analyses middle school students’ interests in biology to provide information on instructional strategies and curriculum development in Korea. An instrument that measures interests was developed based on the middle school biology curriculum. It consists of 64 three‐point Likert‐type items (scores range from 0 to 2). The two components, ‘topic’ and ‘activity’, are composed of 64 items. The topic component and the activity component contain 11 domains and six domains respectively. Data were collected from 267 middle school students in Seoul (male: 169, female: 107). The levels of interest in topic and activity were almost the same and not high. The highest interest domains were ‘genetics’ in topics and ‘observing through a microscope’ in activities. The interest levels in the domain ‘plant morphology’ and ‘plant‐related activity’ were the lowest in each component. The interest level of the eighth graders was the highest found among students. Interest levels of females were lower than those of males in ‘environment and ecosystem’, ‘animal reproduction’ and ‘animal morphology’, but higher in ‘plant morphology’ and ‘plant related activity’ (p < 0.05). Among the topics, the ‘human biology’ domain correlated positively with the domains ‘genetics’, ‘environment and ecosystem’ and ‘respiration of animal and plant’. The correlation between the domains of ‘plant reproduction and nutrition’ and ‘plant development’ was significant in ‘activity’ (r > 0.50, p < 0.001). Consistencies in interests were suggested with respect to instructional strategy and curriculum design.     

Parenting Style as a Moderator for Students’ Academic Achievement

Parenting styles have always been a crucial factor in influencing all aspects of a person??s development. The purpose of this study is to test the structural equation model of academic achievement among the students using parenting styles as a moderator. The sample comprised 493 students from eight schools. Parenting styles are determined using the Parental Authority Questionnaire (Buri in J Pers Assess 57:110?C119, 1991). Academic achievement is measured based on the students?? performance in the Lower Secondary Assessment. Data were analyzed using structural equation modelling. Results demonstrated that model of authoritative and model of authoritarian fit the data of this study well. Both authoritative and authoritarian parenting styles are the most common practice of the parents. Parenting styles have been found to be a moderator of this study. The results indicated that parenting styles moderated the effect of academic self-concept on academic achievement. The impact of academic self-concept on academic achievement is found to be greater for the authoritative than the authoritarian parenting style.     

‘Unconscious’ inclusion of students with learning disabilities in a Malaysian mainstream primary school: teachers' perspectives

The inclusion of children with special needs in mainstream regular schools has been seen as the best practice in special education provision, most markedly since the 90s. International research has provided amassing evidence towards the advantages of inclusive model over a segregation model of special education provision. However, nearly two decades after the signing of the international pledge, namely the Salamanca Statement (UNESCO) towards accepting inclusive education, Malaysia has not yet fully gained the momentum to implement inclusive education for children with special needs, especially for children identified within the category of learning disabilities. Because of the delay in policy implementation, inclusive education remains sparingly practiced in some schools without formal support. This study aims to investigate a scenario of this practice in a mainstream primary school via interviewing the regular teachers. The ultimate aim of this investigation is to identify ways to move forward from the current practice of ‘unconscious inclusion’.     

Construction and Validation of a Chinese Value of Learning Scale (CVLS)

The Chinese Value of Learning Scale (CVLS) is a 5-item instrument for assessing the value of learning in Chinese culture. The psychometric properties of CVLS were investigated in a convenient sample of 583 Chinese soon-to-be-aged adults in Hong Kong. CVLS possesses high internal consistency and exhibited satisfactory short-term test-retest reliability. CVLS also exhibited high face validity and mild convergent validity with other 48-item openness-to-experience scale (OTES) from Revised NEO Personality Inventory, and is significantly related to the past and actual learning experience. In view of its brevity and easy administration, CVLS offers a useful instrument to further investigate the value of learning in Chinese culture and its possible relationship with adults' learning behaviour.     

Applying the communication theory of Diffusion of Innovations to economic sciences: a response to the ‘Using gossips to spread information’ experiments conducted by the 2019 Nobel Laureates

ABSTRACT

Drs Abhijit Banergee, Esther Duflo, and Michael Kremer won the 2019 Nobel Prize in Economic Sciences for their remarkable series of large-scale field experiments to lessen global poverty. The main theoretical framework that they employed was the diffusion of innovations research and practice paradigm (DOI) which has had a long presence in communication research dating back to the 1940s. Here, we reviewed the Nobel laureates’ article, ‘Using gossips to spread information: Theory and evidence from two randomized controlled trials,’ that is illustrative of how economists applied the communication theory of diffusion of innovations to their projects of social change. The present article poses questions and makes recommendations for similar future projects from a communication perspective.     

Early event‐related potentials differences in orthographic processing of native and non‐native Chinese readers

Efficient Chinese character reading requires rapid access to orthographic representations of radical form and position. This study identified the temporal sequence of radical form, radical position and lexicality processing in adult first language (L1) and intermediate second language (L2) Chinese readers. Event‐related potential responses in a one‐back repetition detection task were submitted to linear mixed‐effects models. Violation of radical position produced P100 effects that were left‐lateralized for L1 readers and right‐lateralized for L2 readers. When controlling for P100 activation, radical position produced a left‐lateralized effect at the N170 for L2 readers but no additional activities for L1 readers. Radical form effects were found at the N270 for L1 readers, where radical form violation produced larger N270. Results suggested that radical representations are position‐specific in initial orthographic processing for both groups. However, different temporal dynamics and topographic distributions suggested divergent radical processing for native versus non‐native readers from the beginning.     

The motivation to study: an analysis of undergraduate engineering students at a Caribbean university

The link between motivation and success is well documented; however, there is still room to problematise motivation in regards to the individual and contextual levels. This study looks at motivation in relation to students studying undergraduate engineering courses at a Caribbean university and seeks to discover the factors that motivate them to study and the factors that keep them motivated. An online questionnaire was constructed using 19 Likert-type questions and 5 questions that allowed for open-ended qualitative responses. The findings reveal that participants tended to be motivated by the increased possibility of desired future careers and tended to stay motivated by a combination of goal-orientation and family support. It is recommended that departments, faculties and institutions deliberate on shared and contextually constructed understandings of why students choose to enrol in particular university courses.     

Interest change and continuity from early adolescence to middle adulthood

The present paper discusses the continuity and change of individuals’ vocational interests by reviewing recent research on interest development across the life course. Five forms of change and continuity were proposed to adequately describe interest development. The developmental trajectory of interests based on a recent meta-analysis by Low, Yoon, Roberts, and Rounds (2005) was presented. Mechanisms resulting in change and continuity are discussed within a biopsychosocial context. Implications for understanding the way interests can simultaneously change and become stable were presented.
