Construction and validation of a questionnaire to assess student satisfaction with mathematics learning materials

Sixth Edition Technological Ecosystems for Enhancing MulticulturalityMathematics is an essential branch for the scientific development and its study is mandatory in most university degrees. However, currently the level of academic performance and motivation of students to learn this science is not the desired one. The students can use different learning tools inside and outside the math classroom, enhancing the quality of the learning materials that are designed essentially to facilitate the learning of mathematics. The present research project aims to determine the validity and reliability of a measurement instrument that allows theassessment of the satisfaction of the students with the availablelearning materials. To fulfill the objectives of this research, the method of survey was used. A study with a quantitative approach was developed, which led to the design and validation of a questionnaire by a group of 7 experts. The validation closed after applying a pilot study with 728 students. It concluded positively, obtaining nine factors that coincide with the revision of the literature: technological quality, quality of content, visual quality, didactic significance, adequacy of content, relationship between theory and practice, involvement, contribution to learning, relevance and interaction between educational actors. The results of this questionnaire provide to the international scientific community with relevant information for the design, selection, and use of study materials in the classrooms, which will contribute to raising the levels of student engagement, and their academic performance in mathematics, secondaril

Immortality Through Mind Uploading and Resurrection

Technology in the last century has flourished exponentially. Previous fantasies are becoming cutting-edge discoveries like global communications, encyclopedic knowledge at the average person’s fingertips, and even medical advances used to improve and extend one’s quality of life and life expectancy. As technology pushes the boundaries of what is possible, ambitious visionaries look to solve the arguably greatest problem known to humanity: death. Transhumanists aiming to use technology to overcome this great human limitation, mortality, present the newest proposed solutions to life’s oldest challenge. One of these solutions, mind uploading, is perhaps the most ambitious, but it is not without its own philosophical hindrances. In contrast, Christian resurrection claims to not only solve the problem of death, it claims to already have a historical model in the person of Jesus Christ

The influence of defects of the fatigue resistance of butt and girth welds in A106B steel

This three-phase study was directed at developing a fitness for service defect acceptance criteria for welds with defect indications. The study focussed on A106 Gr. B steel pipe. The first phase involved a literature search and critical review to develop the preliminary acceptance criteria to the extent permitted by the data. The second phase developed data for flat plate, wall segment, and vessel specimens containing artificial or natural planar or volumetric defects. The final phase developed acceptance criteria from the test data

Tissue location of resistance in apple to the rosy apple aphid established by electrical penetration graphs

A study of the constitutive resistance of the apple cultivar Florina, Malus domestica Borkh. (Rosaceae), to the rosy apple aphid, Dysaphis plantaginea (Passerini) (Homoptera Aphididae), was performed for the first time by the electrical penetration graph (DC-EPG) system, using the susceptible apple cultivar Smoothe as control. All experiments were conducted with apterous adult virginoparae. The results showed a constitutive resistance in Florina due to a much longer period before the first probe reflecting surface factors. Some weak indications were found for pre-phloem resistance and initiating phloem access was not affected as inferred from equal time to show phloem salivation. However, the complete absence of phloem ingestion indicates a major resistance factor in the phloem sieve elements, most likely in the sieve element sap. Surface factors could have affected tissue related variables and this should be studied further. Anyhow, the strong constitutive resistance in Florina, either on the surface alone or in the phloem as well, effectively prevented reliable experiments on induced resistance, previously detected by molecular methods

Introduction to the proceedings of the symposium Fish Larvae and Systematics: Ontogeny and relationships

The International Larval Fish Conference was held in Sydney, Australia (26- 30 June 1995) as part of the 19th Annual Meeting of the Early Life History Section of the American Fisheries Society. At the conference, we convened a symposium ( Fish Larvae and Systematics: Ontogeny and Relationships ) that was intended to stimulate the application of ontogenetic data to solve problems in fish systematics. The brief we gave the contributors to the symposium was this: The theme of this symposium will be the use of information gained from egg and larval ontogeny in solving problems in systematics and phylogeny. Thus, we are seeking, not papers that just described larval development of various taxa (although we anticipate many papers will include this), but papers which go beyond description and use the larval characters, developmental patterns, etc. to attack problems in fish systematics. For example, we would welcome papers on how larval morphology solved problems of cryptic species amongst adults, or papers that made use of ontogenetic information to assess relationships at species, genus, family or higher level. Twenty-one papers by authors from 10 countries were presented at this successful symposium

Behavioral ontogeny in larvae and early juveniles of the giant trevally (Caranx ignobilis) (Pisces: Carangidae)

Behavior of young (8−18 mm SL) giant trevally (Caranx ignobilis), a large coral-reef−associated predator, was observed in the laboratory and the ocean. Size was a better predictor of swimming speed and endurance than was age. Critical speed increased with size from 12 to 40 cm/s at 2.7 cm/s for each mm increase in size. Mean scaled critical speed was 19 body lengths/s and was not size related. Swimming speed in the ocean was 4 to 20 cm/s (about half of critical speed) and varied among areas, but within each area, it increased at 2 cm/s for each mm increase in size. Swimming endurance in the laboratory increased from 5 to 40 km at 5 km for each mm increase in size. Vertical distribution changed ontogenetically: larvae swam shallower, but more variably, and then deeper with growth. Two-thirds of individuals swam directionally with no ontogenetic increase in orientation precision. Larvae swam offshore off open coasts, but not in a bay. In situ observations of C. ignobilis feeding, interacting with pelagic animals, and reacting to reefs are reported. Manus

Desarrollo de la morfología y la natación en las larvas de un pez de arrecifes de coral, grama real, Gramma loreto (Grammatidae: Teleostei)

We used reared larvae of Gramma loreto sized 5.5 to 10.5 mm to study ontogeny of morphology and swim- ming. The larvae are slender to moderate in depth, with laterally compressed bodies, about 28 myomeres, a coiled gut that is not compact, extending to 50% to 60% of body length, an inconspicuous gas bladder, head spination limited to tiny preopercular spines, no pectoral-girdle spination, more spines than soft rays in the dorsal fin, and fins without elongate or early-forming elements. The limited pigment is most prominent along the base of the dorsal and anal fins. The development of critical speed (Ucrit) in G. loreto larvae was similar to that of other warm-water species, but speed ranged from 0.2 to 13.5 cm s-1 (mean 7.3, SE 0.7, body lengths s-1), which is relatively slow. Increase in speed with size was linear at 2.7 cm s-1 per mm increase in size. The actual and relative Ucrit of G. loreto were low, and only the four largest, fastest larvae would have been swimming in an inertial hydrodynamic environment. Therefore, for most of their pelagic larval duration the ability of G. loreto larvae to influence their dispersal by horizontal swimming is likely to be low compared with that of many other warm-water fish species.Hemos utilizado larvas cultivadas de Gramma loreto, 5.5-10.5 mm, para estudiar el desarrollo ontogénico en morfología y natación. Las larvas son delgadas o moderamente gruesas, con cuerpos comprimidos lateralmente, con 28 miómeros, un tubo digestivo en espiral, no compacto y que se extiende hasta el 50-60% de la longitud del cuerpo, con una vejiga natatoria inconspicua, espinas en la cabeza limitadas a diminutas espinas preoperculares, sin espinas en la pectoral, mayor número de espinas que de radios blandos en la aleta dorsal, y aletas sin elementos alargados. La pigmentación es limitada, siendo más prominente a lo largo de la base de las aletas dorsal y anal. El desarrollo de la velocidad crítica (Ucrit) en las larvas de G. loreto fue similar al de otras especies de aguas cálidas, sin embargo la velocidad varió de 0.2 a 13.5 cm s-1 (promedio 7.3, ES 0.7, longitud del cuerpo s-1), lo que es relativamente lento. El incremento de velocidad con la talla fue lineal a 2.7 cm s-1 por mm de incremento en talla. La Ucrit real y la relativa de G. loreto fue baja, y solamente las cuatro larvas más grandes y más rápidas , hubieran nadado en un ambiente hidrodinámico inercial. Por tanto, durante la mayor parte de su periodo larvario pelágico la capacidad de las larvas de G. loreto para influir en su dispersión por la natación horizontal es probablemente baja en comparación con muchas otras especies de peces de aguas cálidas
