Facilitating Learning in an Interactive Science Simulation: The Effects of Task Segmentation Guidance on Adults’ Inquiry-Based Learning and Cognitive Load

The current study investigated how a guidance method that segments a complex task into simpler subtasks affects adults’ inquiry-based learning in a science simulation environment. In a multivariate inquiry task, participants were asked to investigate the effects of all variables in one round of inquiry. In another group, participants were guided to investigate the effect of one variable at a time. The results indicate that the guided participants conducted more systematic and comprehensive investigations and reported a lower level of cognitive load compared with the unguided participants. The current findings provide implications for designing simulation-based learning environments to facilitate learning.

An Exploration of Indonesian Postgraduate Students’ Conceptions of Learning

Abstract

This study sets out to explore and model selected aspects of the approaches to, and conceptions of, learning by Indonesian postgraduate students. Meyer's Experiences of Learning Inventory was administered to 105 postgraduate students at the University of Indonesia in 1995. In 1996, Meyer and Boulton‐Lewis's Reflections on Learning Inventory was administered to a separate group of 94 postgraduate students studying at the same University. An initial finding is that, for a Javanese subgroup of responses, some established operationalised constructs collectively associated with a broader ‘meaning orientation’ to learning, in particular a ‘deep approach’, exhibit low values of internal consistency (alphas between 0.18 and 0.51; ‘deep approach'= 0.28). In contrast, non‐Javanese responses exhibit acceptably higher values of internal consistency (alphas between 0.54 and 0.76; ‘deep approach’ = 0.60). Further contrasts between these two subgroups emerge in terms of exploratory factor structures (of conceptions of learning and related effects). It is argued that an understanding of variation in students’ conceptions of learning, and the influence of these conceptions on the experiences of postgraduate students, can assist supervisors and support staff to better assist them during their candidature. Such assistance, while being important for local postgraduate students, takes on an added dimension when students and supervisors are working within a cross‐cultural setting.     

Investigating Turkish Primary School Students’ Interest in Science by Using Their Self-Generated Questions

This paper reports on an attempt to investigate Turkish primary school students’ interest in science by using their self-generated questions. We investigated students’ interest in science by analyzing 1704 self-generated science-related questions. Among them, 826 questions were submitted to a popular science magazine called Science and Children. Such a self-selected sample may represent a group of students who have a higher level of motivation to seek sources of information outside their formal education and have more access to resources than the students of low social classes. To overcome this problem, 739 students were asked to write a question that they wanted to learn from a scientist and as a result 878 questions were gathered. Those students were selected from 13 different schools at 9 cities in Turkey. These schools were selected to represent a mixture of socioeconomic areas and also to cover different students’ profile. Students’ questions were classified into two main categories: the field of interest and the cognitive level of the question. The results point to the popularity of biology, astrophysics, nature of scientific inquiry, technology and physics over other science areas, as well as indicating a difference in interest according to gender, grade level and the setting in which the questions were asked. However, our study suggests that only considering questions submitted to informal learning environments, such as popular science magazines or Ask-A-Scientist Internet sites has limitations and deficiencies. Other methodologies of data collection also need to be considered in designing teaching and school science curriculum to meet students’ needs and interest. The findings from our study tend to challenge existing thinking from other studies. Our results show that self-generated questions asked in an informal and a formal setting have different patterns. Some aspects of students’ self-generated questions and their implications for policy, science curriculum reform and teaching are discussed in this paper.     

Do Science Teachers Distinguish Between Their own Learning and the Learning of Their Students?

Learning beliefs influence learning and teaching. For this reason, teachers and teacher educators need to be aware of them. To support students’ knowledge construction, teachers must develop appropriate learning and teaching beliefs. Teachers appear to have difficulties when analysing students’ learning. This seems to be due to the inability to differentiate the beliefs about their students’ learning from those about their own learning. Both types of beliefs seem to be intertwined. This study focuses on whether pre-service teachers’ beliefs about their own learning are identical to those about their students’ learning. Using a sample of pre-service teachers, we measured general beliefs about “constructivist” and “transmissive” learning and science-specific beliefs about “connectivity” and “taking pre-concepts into account”. We also analysed the development of these four beliefs during teacher professionalisation by comparing beginning and advanced pre-service teachers. Our results show that although pre-service teachers make the distinction between their own learning and the learning of their students for the general tenets of constructivist and transmissive learning, there is no significant difference for science-specific beliefs. The beliefs pre-service teachers hold about their students’ science learning remain closely tied to their own.     

An Exploration of Secondary Students’ Mental States When Learning About Acids and Bases

This study explored factors of students’ mental states, including emotion, intention, internal mental representation, and external mental representation, which can affect their learning performance. In evaluating students’ mental states during the science learning process and the relationship between mental states and learning achievement, valid, reliable, and scalable measures of students’ mental states and learning achievement are needed. This paper presents the development of the Mental State Conceptual Learning Inventory (MSCLI) to identify students’ mental states before and after learning about acids and bases. This instrument is time efficient and convenient and can be administered to large student samples so that teachers and researchers can gain profound insights into their students’ learning of acids and bases in science class. The results of this study indicate that students’ mental states are highly correlated with their achievement. As a whole, low-achieving students tended to have negative emotions and low intentions, were not good at internal visualization, and were unable to interpret graphics and draw pictures. In contrast, high-achieving students had positive emotions and intentions when learning life-related topics about acids and bases, and were good at internal visualization and drawing and interpreting graphics.     

Effects of a Collaborative Science Intervention on High Achieving Students’ Learning Anxiety and Attitudes toward Science

This study investigated the effects of a collaborative science intervention on high achieving students’ learning anxiety and attitudes toward science. Thirty‐seven eighth‐grade high achieving students (16 boys and 21 girls) were selected as an experimental group who joined a 20‐week collaborative science intervention, which integrated and utilized an innovative teaching strategy. Fifty‐eight eighth‐grade high achieving students were selected as the comparison group. The Secondary School Student Questionnaire was conducted to measure all participants’ learning anxiety and attitudes toward science. In addition, 12 target students from the experimental group (i.e., six active and six passive students) were recruited for weekly classroom observations and follow‐up interviews during the intervention. Both quantitative and qualitative findings revealed that experimental group students experienced significant impact as seen through increased attitudes and decreased anxiety of learning science. Implications for practice and research are provided.     

The Impact of Teachers and Their Science Teaching on Students’ ‘Science Interest’: A four-year study

There is a crisis in school science in Australia and this may be related to insufficient students developing an interest in science. This extended study looked at changes in 14 students’ interest in science as they moved through junior secondary school into Year 10. Although the majority of these students still had an interest in science in Year 10, it had fluctuated for most students from year to year. The presence or absence of simple, but effective, teaching practices, identified by these students, seems to suggest one way to retain or improve situational and, it would appear, in several cases, personal interest.     

Uncovering Students’ Environmental Identity: An Exploration of Activities in an Environmental Science Course

This study at a public high school in the Northeastern United States explores how students’ environmental identities are affected by various activities in an Environmental Science course. Data was collected as part of an ethnographic study involving an Environmental Science teacher and her tenth–twelfth grade students. The results focus on interviews with 10 students and the teacher, conducted at three points during the semester-long course. The findings illuminate ways in which students’ identities (environmental and consumer-materialist) are affirmed or disconfirmed during classroom activities, the importance of establishing personal connections with environmental issues, and challenges related to the teaching of controversial environmental issues.     

Using Technology-Enhanced Inquiry-Based Instruction to Foster the Development of Elementary Students’ Views on the Nature of Science

The Next Generation Science Standards support understanding of the nature of science as it is practiced and experienced in the real world through interconnected concepts to be imbedded within scientific practices and crosscutting concepts. This study explored how fourth and fifth grade elementary students’ views of nature of science change when they engage in a technology-enhanced, scientific inquiry-oriented curriculum that takes place across formal and informal settings. Results suggest that student engagement in technology-enhanced inquiry activities that occur in informal and formal settings when supported through explicit instruction focused on metacognitive and social knowledge construction can improve elementary students’ understanding of nature of science.

Development and Validation of an Instrument to Measure Students’ Motivation and Self‐Regulation in Science Learning

Students’ motivational beliefs and self‐regulatory practices have been identified as instrumental in influencing the engagement of students in the learning process. An important aim of science education is to empower students by nurturing the belief that they can succeed in science learning and to cultivate the adaptive learning strategies required to help to bring about that success. This article reports the development and validation of an instrument to measure salient factors related to the motivation and self‐regulation of students in lower secondary science classrooms. The development of the instrument involved identifying key determinants of students’ motivation and self‐regulation in science learning based on theoretical and research underpinnings. Once the instrument was developed, a pilot study involving 52 students from two Grade 8 science classes was undertaken. Quantitative data were collected from 1,360 students in 78 classes across Grades 8, 9, and 10, in addition to in‐depth qualitative information gathered from 10 experienced science teachers and 12 Grade 8 students. Analyses of the data suggest that the survey has strong construct validity when used with lower secondary students. This survey could be practically valuable as a tool for gathering information that may guide classroom teachers in refocusing their teaching practices and help to evaluate the effectiveness of intervention programmes.     

Students’ and Teachers’ Perceptions of Using Video Games to Enhance Science Instruction

Science education video game research points toward promising, but inconclusive results in both student learning outcomes and attitudes. However, student-level variables other than gender have been largely absent from this research. This study examined how students’ reading ability level and disability status are related to their video game-playing behaviors outside of school and their perceptions about the use of science video games during school. Thirty-four teachers and 876 sixth- through ninth-grade students from 14 states participated in the study. All student groups reported that they would prefer to learn science from a video game rather than from traditional text, laboratory-based, or Internet environments. Chi-square analyses indicated a significant association between reading ability level, disability status, and key areas of interest including students’ use of video games outside of school, their perceptions of their scientific abilities, and whether they would pursue a career in the sciences. Implications of these findings and areas for future research are identified.     

Construction and Validation of an Instrument to Measure Taiwanese Elementary Students’ Attitudes toward Their Science Class

The main purpose of this study is to develop a valid and reliable instrument for measuring the attitudes toward science class of fourth‐ and fifth‐grade students in an Asian school culture. Specifically, the development focused on three science attitude constructs—science enjoyment, science confidence, and importance of science as related to science class experiences. A total of 265 elementary school students in Taiwan responded to the instrument developed. Data analysis indicated that the instrument exhibited satisfactory validity and reliability with the Taiwan population used. The Cronbach’s alpha coefficient was 0.93 for the entire instrument indicating a satisfactory level of internal consistency. However, both principal component analysis and parallel analysis showed that the three attitude scales were not unique and should be combined and used as a general “attitudes toward science class” scale. The analysis also showed that there were no gender or grade‐level differences in students’ overall attitudes toward science class.     

The Effect of Student-Centered Approaches on Students’ Interest and Achievement in Science: Relevant Topic-Based,Open and Guided Inquiry-Based,and Discussion-Based Approaches

Since students have lost their interest in school science, several student-centered approaches, such as using topics that are relevant for students, inquiry-based learning, and discussion-based learning have been implemented to attract pupils into science. However, the effect of these approaches was usually measured in small-scale research, and thus, the large-scale evidence supporting student-centered approaches in general use is insufficient. Accordingly, this study aimed to investigate the effect of student-centered approaches on students’ interest and achievement by analyzing a large-scale data set derived from Program for International Student Assessment (PISA) 2006, to add evidence for advocating these approaches in school science, and to generalize the effects on a large population. We used Finnish PISA 2006 data, which is the most recent data that measures science literacy and that contains relevant variables for the constructs of this study. As a consequence of the factor analyses, four teaching methods were grouped as student-centered approaches (relevant topic-based, open and guided inquiry-based, and discussion-based approaches in school science) from the Finnish PISA 2006 sample. The structural equation modeling result indicated that using topics relevant for students positively affected students’ interest and achievement in science. Guided inquiry-based learning was also indicated as a strong positive predictor for students’ achievement, and its effect was also positively associated with students’ interest. On the other hand, open inquiry-based learning was indicated as a strong negative predictor for students’ achievement, as was using discussion in school science. Implications and limitations of the study were discussed.     

High-School Students’ Epistemic Knowledge of Science and Its Relation to Learner Factors in Science Learning

The purpose of this study was to develop and validate an online contextualized test for assessing students’ understanding of epistemic knowledge of science. In addition, how students’ understanding of epistemic knowledge of science interacts with learner factors, including time spent on science learning, interest, self-efficacy, and gender, was also explored. The participants were 489 senior high school students (244 males and 245 females) from eight different schools in Taiwan. Based on the result of an extensive literature review, we first identified six factors of epistemic knowledge of science, such as status of scientific knowledge, the nature of scientific enterprise, measurement in science, and so on. An online test was then created for assessing students’ understanding of the epistemic knowledge of science. Also, a learner-factor survey was developed by adopting previous PISA survey items to measure the abovementioned learner factors. The results of this study show that; (1) by factor analysis, the six factors of epistemic knowledge of science could be grouped into two dimensions which reflect the nature of scientific knowledge and knowing in science, respectively; (2) there was a gender difference in the participants’ understanding of the epistemic knowledge of science; and (3) students’ interest in science learning and the time spent on science learning were positively correlated to their understanding of the epistemic knowledge of science.     

Promoting Students’ Interest and Motivation Towards Science Learning: the Role of Personal Needs and Motivation Orientations

This study aimed to design a teaching sequence for science education that enabled lower secondary school students to enhance their motivation towards science. Further, it looked to examine the way the designed teaching sequence affected students with different motivational profiles. Industry site visits, with embodied theory-based motivational features were included as part of the designed teaching sequence. The sequence was implemented in Finland and Greece with 54 participants, 27 from each country. Quantitative data was collected using the Evaluation of Science Inquiry Activities Questionnaire, based on the Intrinsic Motivation Inventory but did not map the expected outcomes. Interviews, however, showed that students with different motivational profiles found aspects within the module that met their psychological needs as explained by Self-Determination Theory. The results offer a perspective to adolescents’ psychological needs along with some insights into how students mediate the way they value an activity in the context of science education.

Teaching Gene Technology in an Outreach Lab: Students’ Assigned Cognitive Load Clusters and the Clusters’ Relationships to Learner Characteristics, Laboratory Variables, and Cognitive Achievement

This study classified students into different cognitive load (CL) groups by means of cluster analysis based on their experienced CL in a gene technology outreach lab which has instructionally been designed with regard to CL theory. The relationships of the identified student CL clusters to learner characteristics, laboratory variables, and cognitive achievement were examined using a pre-post-follow-up design. Participants of our day-long module Genetic Fingerprinting were 409 twelfth-graders. During the module instructional phases (pre-lab, theoretical, experimental, and interpretation phases), we measured the students’ mental effort (ME) as an index of CL. By clustering the students’ module-phase-specific ME pattern, we found three student CL clusters which were independent of the module instructional phases, labeled as low-level, average-level, and high-level loaded clusters. Additionally, we found two student CL clusters that were each particular to a specific module phase. Their members reported especially high ME invested in one phase each: within the pre-lab phase and within the interpretation phase. Differentiating the clusters, we identified uncertainty tolerance, prior experience in experimentation, epistemic interest, and prior knowledge as relevant learner characteristics. We found relationships to cognitive achievement, but no relationships to the examined laboratory variables. Our results underscore the importance of pre-lab and interpretation phases in hands-on teaching in science education and the need for teachers to pay attention to these phases, both inside and outside of outreach laboratory learning settings.
