Pre-service teachers' use of problem-solving in primary science

The use of problem-solving in science instruction implies a change in the teacher's role from dispensing content information to encouraging critical reflective thinking in the student. For problem-solving to become an integral part of the science curriculum, teachers must make it the focus of their instruction. This study investigated the extent to which pre-service primary teachers used the problem-solving approach in their science instruction. It also identified the factors affecting their efforts to teach science using this approach. The issues considered are important in whether problem-solving becomes part of the science curriculum, as teaching behaviour influences student learning outcomes.

Transformation for adults in an Internet‐based learning environment—is it necessary to be self‐directed?

This research explores the relationships between self‐directed learning readiness and transformative learning theory (TLT) reflected by the Constructivist Internet‐based Learning Environment Scale (CILES). A questionnaire survey about adult learner's perceptions of Internet‐based learning was administered to adults enrolled in classes in community colleges in Taiwan. A total of 593 valid questionnaires were used for the structural equation modeling analysis. The findings confirmed a second‐order hierarchical factor relationship of TLT (technical, dialectical and emancipatory learning interests) from CILES. Moreover, the three domains of learning interests of transformative learning were proved to have a developmental relationship, moderated by the readiness of self‐directed learning for adult learners in Internet‐based learning.     

Identification of dysfunctional cooperative learning teams and troubled individuals

In cooperative learning, students work together as a team to maximize the academic success of all the team members. The failure of even a single member can compromise the success of the entire team. Thus, to evaluate the functioning of the team reliably, it is necessary to consider both the performance of the individual team members and the interactions among them. In this study, a method was developed for identifying dysfunctional teams and troubled individuals by examining the correlation between the team scores obtained in sequential tests and the correlation between the scores obtained by the different team members. The effectiveness of the proposed method was evaluated via field experiments. Forty‐eight students were randomly assigned to cooperative learning teams and their learning performance assessed by four‐unit tests. The results indicated that the proposed method can identify the most troubled individuals in a team even when the team performance/grouping information is not taken explicitly into account. Furthermore, when the team information is considered, the method can identify both the dysfunctional teams and the troubled individuals within the teams. Therefore, the proposed method provides a useful basis for the development of computer‐assisted solutions for assessing the performance of cooperative learning teams.     

Knowledge sharing among Malaysian universities’ students: do personality traits,class room and technological factors matter?

Active and voluntarily sharing of knowledge is an essential element of effective and meaningful learning at university level. Recognising the role and importance of Big Five personality traits (extraversion, conscientiousness, agreeableness, emotional stability and openness) in encouraging knowledge-sharing behaviour, this paper adds the classroom (instructor support and degree of competition) and technological factors (technology availability and support) to model general knowledge-sharing patterns. Survey instrument was used to collect from six private and six public universities in Malaysia. Out of 700 surveys distributed, 474 data were used for analysis representing the response rate of 67.71%. Extraversion, conscientiousness, instructor support, degree of competition and technology support are found to have positive relationship with knowledge-sharing patterns. However, emotional stability is found to have negative relationship. A practical implication of these results is that instructors could advance knowledge sharing via personnel screening in forming assignment groups in their class as well as providing sufficient support and technology support to promote knowledge sharing among students.     

Perspectives on learning to teach science: insights and dilemmas from a collaborative practicum project

In this article we discuss the theoretical and practical rationale for establishing a collaborative science practicum project and report on the findings of the first two years. The project was designed to strengthen the communication links among the school‐based educators, the pre‐service teachers, and the university‐based educators, in order to address the seemingly intractable problems associated with initiating new science teachers into the varied social practices of the teaching profession. Our findings are organized and discussed in the form of three dilemmas (Cuban 1992). These dilemmas are associated with the difficulties the pre‐service teachers had in connecting the propositional knowledge presented in the university setting with the procedural knowledge required in the school setting, and the lack of familiarity by the university and school‐based educators of each other's practice setting. We describe results that resonate with similar issues reported in other collaborative projects, and propose an alternative approach for preparing science teachers. This approach is based on conceptualizing learning to teach as a cognitive apprenticeship (Hennessy 1993) which prepares pre‐service teachers to enter the ‘community of practice’ called teaching. We argue that the success of such an approach requires the development of a collaborative community in which all participants engage in meaningful and supportive discourse concerning what, when and how science is taught in the classroom.

Vertical stream curricula integration of problem-based learning using an autonomous vacuum robot in a mechatronics course

Difficulties in teaching a multi-disciplinary subject such as the mechatronics system design module in Departments of Mechatronics Engineering at Temasek Polytechnic arise from the gap in experience and skill among staff and students who have different backgrounds in mechanical, computer and electrical engineering within the Mechatronics Department. The departments piloted a new vertical stream curricula model (VSCAM) to enhance student learning in mechatronics system design through integration of educational activities from the first to the second year of the course. In this case study, a problem-based learning (PBL) method on an autonomous vacuum robot in the mechatronics systems design module was proposed to allow the students to have hands-on experience in the mechatronics system design. The proposed works included in PBL consist of seminar sessions, weekly works and project presentation to provide holistic assessment on teamwork and individual contributions. At the end of VSCAM, an integrative evaluation was conducted using confidence logs, attitude surveys and questionnaires. It was found that the activities were quite appreciated by the participating staff and students. Hence, PBL has served as an effective pedagogical framework for teaching multidisciplinary subjects in mechatronics engineering education if adequate guidance and support are given to staff and students.     

Roles of position, stress, and proficiency in L2 children’s spelling: A developmental perspective

This study investigated the roles of phoneme position, stress, and proficiency in L2 spelling development by Taiwanese students learning English as a Foreign Language (EFL), an alphabetic writing system typologically different from the learners’ L1 logographic system. Structured nonword spelling tests were administered to EFL sixth-graders with lower and higher English proficiency level. The results showed that overall, final phonemes were spelled more poorly than their initial and medial counterparts; however, phoneme position effect decreased as learners’ English proficiency improved. Secondly, spelling of the stressed syllable was significantly better than that of the unstressed syllable. However, when phonemes were held constant, stress effect was significant only in the first, but not in the second syllable. Thirdly, higher proficient EFL children spelled significantly better than their lower proficient counterparts, and spelling errors were more systematic in the former. The findings of the study are discussed from linguistic, psychological, and developmental perspectives.
