Making Connections: Learning and Teaching Chemistry in Context

Even though several studies have reported positive attitudinal outcomes from context-based chemistry programs, methodological obstacles have prevented researchers from comparing satisfactorily the chemistry-learning outcomes between students who experience a context-based program with those who experience a content-driven program. In this narrative inquiry we are able to address the question: how do the recalled experiences of a student and her teacher in context-based and concept-based chemistry programs compare? From the student’s unique perspective of experiencing both programs with the same teacher, we have constructed our collective account around four themes; namely, the extent to which the student makes connections between chemistry concepts and real-world contexts, developing research independence through engaging in extended experimental investigations related to contexts, learning chemistry concepts through contexts, and conceptual sequencing in a context-based program. The student reported real-world connections between chemistry concepts and contexts, found her engagement in the context-driven tasks interesting and productive, and identified connected sequences of concepts across the contexts studied. Despite difficulties for teachers who are required to shift pedagogies, the student’s lived experiences and outcomes from a context-based program provide some encouragement in working through these issues.     

Portrait of Filipino teachers’ classroom practices: traditional or constructivist?

The intent of this qualitative study is to narrate (Brodkey, (1987a). Education Quarterly, 18, 67–76; Written communication, 4, 25–70; Qualitative communication research methods. (1987b). Lindlof, (1995). (pp. 172–174): London Sage Publications) the master teachers as aggregate sample subjects’ pedagogical understanding and classroom practices. A qualitative analysis of the classroom activities and journal entries of 13 teacher-participants in the Basic Education Curriculum core learning areas is included. Findings reveal that the subject participants’ pedagogical practices still verging toward the formal suggest a traditional inclination. However, the importance of change should be realized. Various concepts of teaching and learning, today, are imperative. Teachers must be resocialized on their new roles and make their students have a more active role in the teaching-learning process.     

What shapes the self-esteem of elderly Filipinos working beyond the retirement age? A structural equation model (SEM)

Previous studies have indicated that major transitions in life such as retirement or exit from working life may contribute to the normative decline in self-esteem. A growing trend on elderly’s labor force beyond retirement invites the conduct of more empirical studies on the dynamics of self-esteem among the elderly group. Anchored on the Self-Determination Theory, this study is an attempt to test a model that examines the impact of social support, health promotion, activities of daily living and anxiety on the self-esteem of a select group of Filipino elderly working beyond the retirement age. Two-hundred eighteen (218) working elderly from the capital of the Philippines participated in this exploratory study. Data gathered from a multi-aspect questionnaire were analyzed using SPSS version 19 and AMOS version 19. Results of structural equation model (SEM) indicated that social support; activities of daily living and health promotion have direct effects on self-esteem, thus supporting the hypotheses. A direct relationship exists between elderly activities of daily living and their social support and anxiety. Notably, an inverse relationship exists between elderly anxiety and factors such as health promotion and self-esteem. The emerged model in this study could serve as valuable tool for nurses in enhancing nursing care aimed at promoting the psychological-well-being and occupational health among the elderly.     

The Impact of Globalization on Teacher Education: The Philippine Perspective

This qualitative study is an attempt to describe how administrators, teachers and researchers in a select group of teacher education institutions (TEIs) in the capital of the Philippines collectively view globalization. Specifically, concepts of a globalized teacher education, impact of globalization in teacher education, and problems of teacher education in the context of globalization were the delineated factors investigated in this study. A total of 23 respondents comprising 13 university teachers, 6 deans and 4 educational researchers were asked to participate in an audio-taped interview and written responses. Data yielded by the interview were transcribed and categorized based on saliency, meaning and homogeneity. Clearly, this study has disclosed efforts initiated at both pre-service and in-service education levels in response to the challenges of globalization consistent with the collective view of the various sectors. This research segment is part of a research project submitted to the Asia-Pacific Education Policy Research Initiative/KEDI (AP-EPRI/KEDI) and funded by the World Bank/GDN.     

Emotional climate of a pre-service science teacher education class in Bhutan

This study explored pre-service secondary science teachers’ perceptions of classroom emotional climate in the context of the Bhutanese macro-social policy of Gross National Happiness. Drawing upon sociological perspectives of human emotions and using Interaction Ritual Theory this study investigated how pre-service science teachers may be supported in their professional development. It was a multi-method study involving video and audio recordings of teaching episodes supported by interviews and the researcher’s diary. Students also registered their perceptions of the emotional climate of their classroom at 3-minute intervals using audience response technology. In this way, emotional events were identified for video analysis. The findings of this study highlighted that the activities pre-service teachers engaged in matter to them. Positive emotional climate was identified in activities involving students’ presentations using video clips and models, coteaching, and interactive whole class discussions. Decreases in emotional climate were identified during formal lectures and when unprepared presenters led presentations. Emotions such as frustration and disappointment characterized classes with negative emotional climate. The enabling conditions to sustain a positive emotional climate are identified. Implications for sustaining macro-social policy about Gross National Happiness are considered in light of the climate that develops in science teacher education classes.

What predicts the malnutrition among a select group of Filipino older persons in institutionalized setting? A partial least square study

The overall intent of this study is to examine the relationship among several factors that influence the malnutrition of a select group of Filipino elderly in institutionalized setting. A total of 102 residents were purposively recruited from three different institutionalized care settings at the national capital region of the Philippines. A multi-aspect questionnaire was used to characterize the demographic and nutrition profiles of the participants. Data were treated statistically using the partial least square design. Notably, the study showed that 48.0% of the elderly residents in institutions were at risk of malnutrition, 36.3% were malnourished, and 15.7% have normal nutritional status. Malnutrition was found to be prevalent among the female group, aged >70 years old, functional impairment (p = <0.01), poor eating habits (p = 0.01), lower dietary intake (p = 0.01), and eating difficulties (p = 0.04). However, statistically significant relationships between eating habits (p = 0.08) and dietary intake and comorbidities (p = 0.32) and malnutrition were not established. Impliedly, administrators of homecare institutions are invited to pay greater attention to the nutritional status of the elderly by institutionalizing nutrition assessment and evaluation practices and nutrition care planning that respond to the identified nutritional needs and concern of the elderly.     

The construct validity of Institutional Commitment: A confirmatory factor analysis

The present study examined the underlying structure of the variable Institutional Commitment by testing for the convergence, or lack thereof, among different indicators of the construct as represented by three theoretical frameworks (Tinto, 1975, 1987; Bean, 1985; Huselid and Day, 1991). Confirmatory factor analyses revealed that Institutional Commitment could be decomposed into two multiple indicators of the same latent construct: a general factor that groups items related to institutional quality, practical value of an education, utility of an education, fit between student and institution, and loyalty to the institution and another factor represented by items indicating similarity of values (Affinity of Values). Moreover, the study established the predictive validity of each subcomponent on different outcomes related to student persistence. While Institutional Commitment was found to have a significant direct effect on both students' intents to persist and actual persistence behavior, Affinity of Values was not as equally predictive of measures of student retention.Paper presented before the 1991 ASHE Annual Meeting.
