Title: TAXONOMIC IDENTIFICATION AND DETECTION OF TRYPTAMINE AND AMATOXIN OF EDIBLE AND NON-EDIBLE MUSHROOMS AND OTHER SPECIES OF PHYLUM BASIDIOMYCOTA FOUND IN CABAGAN, ISABELA (A PRELIMINARY STUDY)
Name: JANE G. CABAUATAN AND YOLANDA M. BUMARLONG
Abstract:

A preliminary study was conducted to present the taxonomy as well as toxins which are most deadly associated with edible and non-edible mushrooms and other species of Phylum Basidiomycota. Standard procedure was utilized in the detection of specific toxins: tryptamine and amtoxin- the Meixner Test. In terms of taxonomic classification, standard format was used based on Botanical Nomenclature.

Thirty (30) fungal organisms were identified with a total of nineteen (19) species of mushroom and eleven (11) other species of fungal organisms were collected, identified and tested for toxins. All species collected belong to Kingdom fungi. Phylum Basidiomycota and Division Eumycota. Seventeen (17) belong to Class Hymenomycota and thirteen (13) from Class Gasteromycota. All these identified fungal organisms belong to seven (70 different orders, namely: Order Polyporales(13), Order Aphyllophorales (3), Order Auricurales (1), Order Polyporales(8), Order Lycoperdales (1), Order Schlerodermatales and one (1) from Order tremellales. Nineteen (19) of the species under this phylum grow during rainy/wet season, and the rest of the identified fungi grow or survive all throughout the year specifically on areas where decomposition process is high. There were eight (8) species of edible and three (3) species of non-edible mushrooms were detected to have no toxin of either tryptamine or amatoxin. These are the following: Edible-Collybia reineckeana, Schizophyllum commune, Volvariella volvaceae, Lentinus sajor-caju, Auricularia polytricha,, Chanterellus cibarius, Pleurotus ulmarius and Agaricus campestris, while Non-edible- Ganoderma lucidum, Ganoderma applanatum and Ganoderma tsugae.. Nineteen (19) other species were detected to be positive in both tryptamine and amatoxin. Tryptamine were detected on species of Lepiota cepaestipes, Fomes spp., Chanterellus spp., Meripillus gigantus., Psylocibe mexicana, Paneolus spp., Lenzites betulina, Armillaria spp., Tremella spp. and Phellinus spp. while amatoxins were revealed by the following fungal organisms: Amanita muscaria,, Amanita phalloides, Amanita virosa, Polysporus brumalis, Scleroderma spp., Lycoperdon ericetorum and Fomes spp.

As simple as the methodology used, mushroom can immediately be identified in terms of the presence of toxic substances but not much with its edibility. Since not all mushroom and other species of these phylum which look good are edible. Therefore, it is recommended that similar study could be conducted using more sophisticated tools for screening and testing of toxins for more reliable information and to prove the claim. And a follow up study should also be done to review or test the best substrate composition of identified edible mushrooms for spawning and food production.

Title: PLANT DIVERSITY AND STATUS OF THE ISU WILDLIFE SANCTUARY
Name: MA. VISITACION D. GUINGAB
Abstract:

A study was conducted to generate knowledge on the flora resources of the Isabela State University Wildlife Sanctuary.

The study revealed a total of 165 plant taxa from the floristic survey area. Of this, 68 or 41.21% were indigenous while 97 or 58.79 % were introduced species to the wildlife sanctuary. Of the 97 introduced species, 20 are native to the Philippines and 77 are exotic. Eleven (11) species were identified as endemic, that is, they are only found in the Philippine archipelago.

An assessment of the status of the different plant species was carried out to establish a foundation for their protection, conservation and monitoring. Assessment of the status of each species revealed ten (10) threatened species both locally and nationally. Among these three (3) are critically endangered or facing an extremely high risk of extinction in the wild. These species belong to the family Dipterocarpaceae as follows: Shorea astylosa (yakal); Shorea contorta (white lauan) and Hopea cagayanensis (narek). All three species are endemic to the Philippine archipelago. Hopea cagayanensis is endemic only to Cagayan province. On the other hand, two (2) are endangered species or facing a very high risk of extinction in the wild: Diospyros philippinensis (kamagong) and Podocarpus costalis (igem-dagat) while five (5) are vulnerable or facing a high risk of extinction in the wild as follows: Afzelia rhomboidea (tindalo), Pterocarpus indicus (narra), Vitex parviflora (molave), Instia bijuga (ipil), and Ficus ulmifolia (tibig).

Title: MOUNT PINATUBO LAHAR AS PHYSICAL BARRIER TO PREVENT TUNNELING AND SOIL PENETRATION OF PHILIPPINE MILK TERMITE (COPTOTERMES VASTATOR LIGHT)
Name: HEHERSON B. ONG
Abstract:

Philippine subterranean termite Coptotermes vastator Light, was tested for its ability to penetrate lahar barrier consisting of uniform or mixed particles ranging in size from 0.71 - 2.36 mm in diameter. Laboratory bioassay showed that lahar particle in the range of 1.0 – 2.36 mm, 1.18 – 2.36 mm and 2.0 – 2.36 mm in diameter prevented penetration of C. vastator. Mixed sized particles with equal proportion of each effective size range were also effective in preventing penetration of the termite.

Title: THE TEACHER ON THE INTERNET: SELF-EFFICACY BELIEFS, USAGE, AND ATTITUDES
Name: AUDREY B. SIMON
Abstract:

This study examined the relationship between and among teachers’ self-efficacy beliefs, usage, and attitude towards the Internet with their personal characteristics such as age, number of years in teaching, computer literacy level, and trainings attended.

A descriptive method of research was used in finding answers to the problems of this study while random sampling method was applied to select the 124 teacher participants from nine campuses of the Isabela State University. This study used a four-part questionnaire and a five-point Likert-type scale in gathering and in interpreting the data. The first part was used to collect the teachers’ personal characteristics. The second part measured the teachers’ Internet self-efficacy. The third part gathered data on the Internet usage of the teachers, and the fourth part measured their attitude towards the Internet. Negatively stated attitude questions were scored in reverse order.

Teacher participants were given one week to complete the questionnaire before the researcher personally retrieved them. The responses were tallied and presented using frequency distribution, weighted mean and percentage distribution. The Pearson Product Moment correlation was used to determine the significant relationships and correlations between and among the variables.

It has been found that: 1) the older the age and the longer a teacher had been in the teaching profession, the less comfortable he or she was in using the Internet; 2) a high computer literacy level and in-service trainings influenced the teachers’ frequency of Internet use, high self-efficacy, and positive attitude towards the Internet; 3) teachers frequency of Internet use increased their self-efficacy and attitude, while a highly positive attitude motivated teachers to frequently use the Internet and increased their self-efficacy; and 4) the more problems the teachers encountered the lesser their usage, the lower their self-efficacy, and the more negative their attitudes were

Title: RADICAL AND SOCIAL CONSTRUCTIVISM AND THE PERFORMANCE OF STUDENTS IN MATHEMATICS
Name: AMBROSE HANS G. AGGABAO
Abstract:

This study compared the effectiveness of three teaching approaches on achievement as well as retention of learning of students. It focused on comparing new teaching approaches that were designed based on constructivist learning philosophies (social and radical constructivism) to current tradition of teaching. Social constructivism used the interactive small-group learning while Radical constructivism used the individualized self-engagement approach. Both were supported with instructional materials and instructional protocol consistent with constructivist philosophies.

The study followed the Equivalent-Groups-Pretest-Posttest Experimental Design. The experiment was conducted using 92 freshmen math students of the Teachers College in 2005 now College of Teacher Education. Results of the study showed significant differences among mean gain scores on both achievement and retention measures. Radical constructivist approach showed significant advantage over the other two approaches, while the social constructivist approach showed better gain scores than the current, traditional teaching approach

Title: ENVIRONMENTAL ATTITUDES AND BEHAVIOR OF STUDENTS IN SELECTED HIGHER EDUCATION INSTITUTIONS IN REGION 02
Name: EILEEN C. BERNARDO
Abstract:

This study sought to determine the attitudes and behavior of students in Higher Education Institutions in Region 2 on some environmental issues and concerns. The study showed that majority of the students (91.6%) are concerned about the environment and considered themselves as environmentalists. Majority perceived that the Philippine government is concerned enough about the environment. Likewise, most of the respondents thought that the Filipino public and businesses and industries in the Philippines were in general, worried enough about the current state of the environment. The students were most concerned with the decrease in the quality of drinking water, air pollution, damage to the ozone layer, garbage disposal and pollution of rivers and they were least concerned with global climate change and radioactive contamination. The main activities performed by the respondents and their families to improve the quality of the environment were volunteering for an environmental group, recycling, and cutting down the household’s use of energy. There is a need to continuously recognize the attitudes and behavior of college students on the environment. To enrich environmental education in the Philippines, global environmental issues and concerns, could be integrated in courses at the tertiary level.

Title: DEVELOPMENT AND EVALUATION OF COMPUTER AIDED TESTING AND INFORMATION (CATI) FOR THE GUIDANCE OFFICE AT ISABELA STATE UNIVERSITY, CABAGAN, ISABELA
Name: ROSALINDA B. GUIYAB
Abstract:

The study Development and Evaluation of Computer Aided Testing and Information (CATI) for the Guidance Office at Isabela State University, Cabagan, Isabela aimed to develop and evaluate a Computer Aided Testing and Information (CATI) for the Guidance Office at Isabela State University, Cabagan, Isabela. The development phase of this study included the design of the CATI, used the Waterfall Model, together with Unified Modeling Language or UML. Specifically, the Use Case Diagram (UCD) to model the interaction between the system and its users. On the other hand, the evaluation phase utilized two methods: technical evaluation with system testing and humanistic evaluation with acceptability of the system. A stratified random sample of ninety two (92) ISUC – CDCAS students and twelve (12) IT experts including the guidance counselor served as respondents of the study. The respondents highly accepted the accuracy, efficiency, reliability and security features of the CATI system. Across all features, the CATI system was consistently adjudged as “highly acceptable”. This information confirmed the need to automate the process used to administer, check and score the university entrance examination as well as keeping the students record. It is recommended that the developed system will be implemented to improve the quality of the present admission system of the university and eventually, managing its students record.

Title: DEVELOPMENT OF A SOURCE MATERIAL FOR TEACHING STUDY AND CRITICAL THINKING SKILLS FOR ESL LEARNERS
Name: BOYET L. BATANG
Abstract:

This paper attempted to present a source material for the teaching of study and critical thinking skills for ESL (English as a second Language) Learners. Specifically, it aimed to determine the critical thinking skills which need to be developed among the ESL Learners and develop a sample source material for the teaching of study and critical thinking skills. The study made use of the descriptive method of research. The task was divided into three stages following Johnson’s model of materials preparation (Johnson, 1972, Guilot, 2000) which included the design, development, and dissemination stages. Results of the study showed that college students obviously have difficulties in reading the disciplines as reported by English Teachers and the Content Area Teachers, and that the developed prototype materials based on ERICA (Effective Reading in the Content Areas) strategies were promising instruments for attaining reading-to-learn objectives. The material appears suitable, acceptable and effective as viewed and perceived by English teachers and the Content Area teachers. It is recommended that teachers of both language and content subjects are enjoined to use the material so that students will be used to using strategies to develop critical thinking skills.
